Mixed Topics

Vancomycin is a widely used IV antibiotic due to its broad-spectrum of activity, bactericidal nature, and low rates of resistance; however, adverse effects (AEs), including nephrotoxicity, are commonly associated with its use.¹ The vancomycin therapeutic monitoring guidelines recognize the incidence of nephrotoxicity and suggest strategies for reducing the risk, including area under the curve/mean inhibitory concentration (AUC/MIC) monitoring rather than trough-only monitoring. Vancomycin-associated acute kidney injury (AKI) has been defined as an increase in serum creatinine (SCr) over a 48-hour period of ≥ 0.3 mg/dL or a percentage increase of ≥ 50%, which is consistent with the Acute Kidney Injury Network (AKIN) guidelines.^2,3 Vancomycin-associated AKI is a common AE, with its incidence reported in previous studies ranging from 10 to 20%.^4,5

The most common crystalloid fluid administered to patients in the United States is 0.9% sodium chloride (NaCl), also known as normal saline (NS), and recent trials have explored its potential to cause AEs.^6-8 Balanced crystalloid solutions, such as Plasma-Lyte and lactated Ringer’s solution (LR), contain buffering agents and lower concentrations of sodium and chloride compared with that of NS. Trials in the intensive care unit (ICU) and emergency department, such as the SMART-MED, SMART-SURG, and SALT-ED have reported a significantly lower rate of AKI when using balanced crystalloids compared with NS due to the concentration of sodium and chloride in NS being supraphysiologic to normal serum concentrations.^6,7 Alternatively, the SPLIT trial evaluated the use of NS compared with Plasma-Lyte for ICU fluid therapy and did not find a statistically significant difference in AKI.⁸ Furthermore, some studies have reported increased risk for hyperchloremia when using NS compared with dextrose 5% in water (D5W) or balanced crystalloids, which can result in metabolic acidosis.^6,7,9,10 These studies have shown how the choice of fluid can have a large effect on the incidence of AEs; bringing into question whether these effects could be additive when combined with the nephrotoxicity associated with vancomycin.^6-9

Vancomycin is physically and chemically stable if diluted in D5W, NS, 5% dextrose in NS, LR, or 5% dextrose in LR.¹ It is not known whether the selection of diluent has an effect on nephrotoxicity or other AEs of vancomycin therapy. Furthermore, clinicians may be unaware or unable to specify which diluent to use. There are currently no practice guidelines that favor one diluent over another for vancomycin; however, trials showing higher rates of AKI and hyperchloremia using NS for fluid resuscitation may indicate an increased potential for vancomycin-associated AKI when using NS as a diluent.^6,7,9 This study was performed to evaluate whether the type of crystalloid used (D5W vs NS) can influence adverse outcomes for patients. While many factors may contribute to these AEs, the potential to reduce the risk of negative adverse outcomes for hospitalized patients is a significant area of exploration.

The primary outcome of this study was the incidence of AKI, defined using AKIN guidelines where the increase in SCr occurred at least 24 hours after starting vancomycin and within 36 hours of receiving the last vancomycin dose.³ AKI was staged using the AKIN guidelines (stage 1: increase in SCr of ≥ 0.3 mg/dL or by 50 to 99%; stage 2: increase in SCr by 100 to 199%; stage 3: increase in SCr by > 200%) based on changes in SCr from baseline during vancomycin therapy or within 36 hours of stopping vancomycin therapy.³ Secondary outcomes included the incidence of hyperglycemia, hyperchloremia, metabolic acidosis, hypernatremia, mortality in hospital, and mortality within 30 days from hospital discharge.

Methods

This single-center, retrospective study of veterans who received IV vancomycin within the North Florida/South Georgia Veterans Health System (NF/SGVHS) in Gainesville, Florida, from July 1, 2015 to June 30, 2020, compared veterans who received vancomycin diluted in NS with those who received vancomycin diluted in D5W to assess for differences in AEs, including AKI, metabolic acidosis (serum bicarbonate level < 23 mmol/L), hyperchloremia (serum chloride levels > 108 mmol/L), hypernatremia (serum sodium > 145 mmol/L), and hyperglycemia (blood glucose > 180 mg/dL). The endpoint values were defined using the reference ranges determined by the local laboratory. At NF/SGVHS, vancomycin is diluted in D5W or NS based primarily on factors such as product availability and cost.

Study Criteria

Veterans were included if they received IV vancomycin between July 1, 2015 and June 30, 2020. The cohorts were grouped into those receiving vancomycin doses diluted in NS and those receiving vancomycin doses diluted in D5W. Veterans were excluded if they received < 80% of vancomycin doses diluted in their respective fluid, if they were on vancomycin for < 48 hours, or if they did not have laboratory results collected both before and after vancomycin therapy to assess a change. There were more patients receiving vancomycin in D5W, so a random sample was selected to have an equal size comparison group with those receiving NS. A sample size calculation was performed with an anticipated AKI incidence of 14%.⁵ To detect a 10% difference in the primary outcome with an α of 0.05 and 75% power, 226 patients (113 in each cohort) were needed for inclusion.

Data were collected using the Data Access Request Tracker tool through the US Department of Veterans Affairs (VA) Informatics and Computing Infrastructure. Data collected included demographics, laboratory data at baseline and during vancomycin therapy, characteristics of antibiotic therapy, and mortality data. Of note, all laboratory values assessed in this study were obtained while the veteran was receiving vancomycin or within 36 hours of receiving the last vancomycin dose to appropriately assess any changes.

Statistical analysis of categorical data were analyzed using a χ² test on the GraphPad online program. This study received institutional review board approval from the University of Florida and was conducted in accordance with protections for human subjects.

Results

A total of 792 veterans received IV vancomycin NF/SGVHS in the defined study period. Of these, 381 veterans were excluded, including having < 80% of doses in a single solution (213 veterans), receiving IV vancomycin for < 48 hours (149 veterans), and not having necessary laboratory data available to assess a change in kidney function (19 veterans). An additional 165 veterans were randomly excluded from the D5W cohort in order to have an equal comparison group to the NS cohort; therefore, a total of 246 veterans were included in the final assessment (123 veterans in each cohort). The median patient age was 73 years (IQR, 68.0, 80.5) in the D5W group and 66 years (IQR, 60.0, 74.0) in the NS group; 83.7% of veterans in the D5W group and 74% veterans in the NS group were white; 94.3% of the D5W group and 100% of the NS group were male (Table 1).

Adverse Effects by Solution

The percentage of AKI in the D5W group was 22.8% compared with 14.6% in the NS group (P = .14), and all cases were classified as stage 1 AKI. Baseline cases of hyperglycemia, hypernatremia, hyperchloremia, or metabolic acidosis were not included in the reported rates of each in order to determine a change during vancomycin therapy (Table 2).

The percentage of patients with hyperglycemia in the D5W group was 32.5% compared with 39.8% in the NS group (P = .29). The percentage of patients with hypernatremia in the D5W group was 15.4% compared with 10.6% in the NS group (P = .34). The percentage of patients with hyperchloremia in the D5W group was 22.8% compared with 17.9% in the NS group (P = .43). The percentage of patients with metabolic acidosis in the D5W group was 48.0% compared with 49.6% in the NS group (P = .90).

Discussion

This retrospective cohort study comparing the AEs of vancomycin diluted in NS and vancomycin diluted with D5W showed no statistically significant differences in the incidence of AKI or any metabolic AEs. Although these results did not show an association between the incidence of AEs and the dilution fluid for vancomycin, other factors may contribute to the overall incidence of AEs. Factors such as cumulative vancomycin dose, duration of therapy, and presence of concomitant nephrotoxins have been known to increase the incidence of AKI and may have a greater impact on this incidence than the fluid used in administering the vancomycin.

These results specifically the incidence of AKI were not consistent with previous trials evaluating the AEs of NS. Based on previous trials, we expected the vancomycin in the NS cohort to have a significantly higher incidence of hypernatremia, hyperchloremia, and AKI. Our results may indicate that the volume of crystalloid received played a greater role on the incidence of AEs. Our study assessed the effect of a diluent for one IV medication that may have been only a few hundred milliliters of fluid per day. The total volume of IV fluid received from vancomycin was not assessed; thus, it is not known how the volume of fluid may have impacted the results.

One consideration with this study is the method used for monitoring vancomycin levels. Most of the patients included in this study were admitted prior to the release of the updated vancomycin guidelines, which advocated for the transition from traditional trough-only monitoring to AUC/MIC. In September 2019, NF/SGVHS ICUs made the transition to this new method of monitoring with a hospital-wide transition following the study end date. The D5W group had a slightly higher percentage of patients admitted to the ICU, thus were more likely to be monitored using AUC/MIC during this period. Literature has shown the AUC/MIC method of monitoring can result in a decreased daily dose, decreased trough levels, and decreased incidence of nephrotoxicity.^11-14 Although the method for monitoring vancomycin has the potential to affect the incidence of AKI, the majority of patients were monitored using the traditional trough-only method with similar trough levels reported in both groups.

Limitations

This study is limited by its retrospective nature, the potential introduction of biases, and the inability to control for confounders that may have influenced the incidence of AEs. Potential confounders present in this study included the use of concomitant nephrotoxic medications, vancomycin dose, and underlying conditions, as these could have impacted the overall incidence of AEs.

The combination of piperacillin/tazobactam plus vancomycin has commonly been associated with an increased risk of nephrotoxicity. Previous studies have identified this nephrotoxic combination to have a significantly increased risk of AKI compared with vancomycin alone or when used in combination with alternative antibiotics such as cefepime or meropenem.^15,16 In our study, there was a higher percentage of patients in the NS group with concomitant piperacillin/tazobactam, so this difference between the groups may have influenced the incidence of AKI. Nephrotoxic medications other than antibiotics were not assessed in this study; however, these also could have impacted our results significantly. While the vancomycin duration of therapy and highest trough levels were similar between groups, the NS group had a larger average daily dose and overall cumulative dose. Studies have identified the risk of nephrotoxicity increases with a vancomycin daily dose of 4 g, troughs > 15 mg/mL, and a duration of therapy > 7 days.^15,16 In our study, the daily doses in both groups were < 4 g, so it is likely the average daily vancomycin dose had little impact on the incidence of AKI.

Another potential confounder identified was assessment of underlying conditions in the patients. Due to the limitations associated with the data extraction method, we could not assess for underlying conditions that may have impacted the results. Notably, the potential nephrotoxicity of NS has mostly been shown in critically ill patients. Therefore, the mixed acutely ill patient sample in this study may have been less likely to develop AKI from NS compared with an exclusively critically ill patient sample.

Selection bias and information bias are common with observational studies. In our study, selection bias may have been present since prospective randomization of patient samples was not possible. Since all data were extracted from the medical health record, information bias may have been present with the potential to impact the results. Due to the single-center nature of this study with a predominantly older, white male veteran patient sample, generalizability to other patient populations may be limited. We would expect the results of this study to be similar among other patient populations of a similar age and demographic; however, the external validity of this study may be weak among other populations. Although this study included enough patients based on sample size estimate, a larger sample size could have allowed for detection of smaller differences between groups and decreased the chance for type II error.

Conclusions

Overall, the results of this study do not suggest that the crystalloid used to dilute IV vancomycin is associated with differences in nephrotoxicity or other relevant AEs. Future studies evaluating the potential for AEs from medication diluent are warranted and would benefit from a prospective, randomized design. Further studies are both necessary and crucial for enhancing the quality of care to minimize the rates of AEs of commonly used medications.

Baseline cases of hyperglycemia, hypernatremia, hyperchloremia, or metabolic acidosis were not included in the reported rates of each in order to determine a change during vancomycin therapy (Table 2).

The percentage of patients with hyperglycemia in the D5W group was 32.5% compared with 39.8% in the NS group (P = .29). The percentage of patients with hypernatremia in the D5W group was 15.4% compared with 10.6% in the NS group (P = .34). The percentage of patients with hyperchloremia in the D5W group was 22.8% compared with 17.9% in the NS group (P = .43). The percentage of patients with metabolic acidosis in the D5W group was 48.0% compared with 49.6% in the NS group (P = .90).

Discussion

This retrospective cohort study comparing the AEs of vancomycin diluted in NS and vancomycin diluted with D5W showed no statistically significant differences in the incidence of AKI or any metabolic AEs. Although these results did not show an association between the incidence of AEs and the dilution fluid for vancomycin, other factors may contribute to the overall incidence of AEs. Factors such as cumulative vancomycin dose, duration of therapy, and presence of concomitant nephrotoxins have been known to increase the incidence of AKI and may have a greater impact on this incidence than the fluid used in administering the vancomycin.

These results specifically the incidence of AKI were not consistent with previous trials evaluating the AEs of NS. Based on previous trials, we expected the vancomycin in the NS cohort to have a significantly higher incidence of hypernatremia, hyperchloremia, and AKI. Our results may indicate that the volume of crystalloid received played a greater role on the incidence of AEs. Our study assessed the effect of a diluent for one IV medication that may have been only a few hundred milliliters of fluid per day. The total volume of IV fluid received from vancomycin was not assessed; thus, it is not known how the volume of fluid may have impacted the results.

One consideration with this study is the method used for monitoring vancomycin levels. Most of the patients included in this study were admitted prior to the release of the updated vancomycin guidelines, which advocated for the transition from traditional trough-only monitoring to AUC/MIC. In September 2019, NF/SGVHS ICUs made the transition to this new method of monitoring with a hospital-wide transition following the study end date. The D5W group had a slightly higher percentage of patients admitted to the ICU, thus were more likely to be monitored using AUC/MIC during this period. Literature has shown the AUC/MIC method of monitoring can result in a decreased daily dose, decreased trough levels, and decreased incidence of nephrotoxicity.^11-14 Although the method for monitoring vancomycin has the potential to affect the incidence of AKI, the majority of patients were monitored using the traditional trough-only method with similar trough levels reported in both groups.

Limitations

This study is limited by its retrospective nature, the potential introduction of biases, and the inability to control for confounders that may have influenced the incidence of AEs. Potential confounders present in this study included the use of concomitant nephrotoxic medications, vancomycin dose, and underlying conditions, as these could have impacted the overall incidence of AEs.

The combination of piperacillin/tazobactam plus vancomycin has commonly been associated with an increased risk of nephrotoxicity. Previous studies have identified this nephrotoxic combination to have a significantly increased risk of AKI compared with vancomycin alone or when used in combination with alternative antibiotics such as cefepime or meropenem.^15,16 In our study, there was a higher percentage of patients in the NS group with concomitant piperacillin/tazobactam, so this difference between the groups may have influenced the incidence of AKI. Nephrotoxic medications other than antibiotics were not assessed in this study; however, these also could have impacted our results significantly. While the vancomycin duration of therapy and highest trough levels were similar between groups, the NS group had a larger average daily dose and overall cumulative dose. Studies have identified the risk of nephrotoxicity increases with a vancomycin daily dose of 4 g, troughs > 15 mg/mL, and a duration of therapy > 7 days.^15,16 In our study, the daily doses in both groups were < 4 g, so it is likely the average daily vancomycin dose had little impact on the incidence of AKI.

Another potential confounder identified was assessment of underlying conditions in the patients. Due to the limitations associated with the data extraction method, we could not assess for underlying conditions that may have impacted the results. Notably, the potential nephrotoxicity of NS has mostly been shown in critically ill patients. Therefore, the mixed acutely ill patient sample in this study may have been less likely to develop AKI from NS compared with an exclusively critically ill patient sample.

Selection bias and information bias are common with observational studies. In our study, selection bias may have been present since prospective randomization of patient samples was not possible. Since all data were extracted from the medical health record, information bias may have been present with the potential to impact the results. Due to the single-center nature of this study with a predominantly older, white male veteran patient sample, generalizability to other patient populations may be limited. We would expect the results of this study to be similar among other patient populations of a similar age and demographic; however, the external validity of this study may be weak among other populations. Although this study included enough patients based on sample size estimate, a larger sample size could have allowed for detection of smaller differences between groups and decreased the chance for type II error.

Conclusions

Overall, the results of this study do not suggest that the crystalloid used to dilute IV vancomycin is associated with differences in nephrotoxicity or other relevant AEs. Future studies evaluating the potential for AEs from medication diluent are warranted and would benefit from a prospective, randomized design. Further studies are both necessary and crucial for enhancing the quality of care to minimize the rates of AEs of commonly used medications.

Yoga is an effective clinical intervention for cancer survivors. Studies indicate a wide range of benefits, including improvements in physical functioning, emotional well-being and overall quality of life.^1-7 Two-thirds of National Cancer Institute designated comprehensive cancer centers offer yoga on-site.⁸ Yoga is endorsed by the National Comprehensive Cancer Network and American Society of Clinical Oncology for managing symptoms, such as cancer-related anxiety and depression and for improving overall quality of life.^9,10

Although the positive effects of yoga on cancer patients are well studied, most published research in this area reports on predominantly middle-aged women with breast cancer.^11,12 Less is known about the use of yoga in other groups of cancer patients, such as older adults, veterans, and those from diverse racial or ethnic backgrounds. This gap in the literature is concerning considering that the majority of cancer survivors are aged 60 years or older, and veterans face unique risk factors for cancer associated with herbicide exposure (eg, Agent Orange) and other military-related noxious exposures.^13,14 Older cancer survivors may have more difficulty recovering from treatment-related adverse effects, making it especially important to target recovery efforts to older adults.¹⁵ Yoga can be adapted for older cancer survivors with age-related comorbidities, similar to adaptations made for older adults who are not cancer survivors but require accommodations for physical limitations.^16-20 Similarly, yoga programs targeted to racially diverse cancer survivors are associated with improved mood and well-being in racially diverse cancer survivors, but studies suggest community engagement and cultural adaptation may be important to address the needs of culturally diverse cancer survivors.^21-23

Yoga has been increasingly studied within the Veterans Health Administration (VHA) for treatment of posttraumatic stress disorder (PTSD) and has been found effective in reducing symptoms through the use of trauma-informed and military-relevant instruction as well as a military veteran yoga teacher.^24-26 This work has not targeted older veterans or cancer survivors who may be more difficult to recruit into such programs, but who would nevertheless benefit.

Clinically, the VHA whole health model is providing increased opportunities for veterans to engage in holistic care including yoga.²⁷ Resources include in-person yoga classes (varies by facility), videos, and handouts with practices uniquely designed for veterans or wounded warriors. As clinicians increasingly refer veterans to these programs, it will be important to develop strategies to engage older veterans in these services.

One important strategy to enhancing access to yoga for older veterans is to consider beliefs about yoga. Beliefs about yoga or general expectations about the outcomes of yoga may be critical to consider in expanding access to yoga in underrepresented groups. Beliefs about yoga may include beliefs about yoga improving health, yoga being difficult or producing discomfort, and yoga involving specific social norms.²⁸ For example, confidence in one’s ability to perform yoga despite discomfort predicted class attendance and practice in a sample of 32 breast cancer survivors.²⁹ Relatedly, positive beliefs about the impact of yoga on health were associated with improvements in mood and quality of life in a sample of 66 cancer survivors.³⁰

The aim of this study was to examine avenues to enhance access to yoga for older veterans, including those from diverse backgrounds, with a focus on the role of beliefs. In the first study we investigate the association between beliefs about and barriers to yoga in a group of older cancer survivors, and we consider the role of demographic and clinical variables in such beliefs and how education may alter beliefs. In alignment with the whole health model of holistic health, we posit that yoga educational materials and resources may contribute to yoga beliefs and work to decrease these barriers. We apply these findings in a second study that enrolled older veterans in yoga and examining the impact of program participation on beliefs and the role of beliefs in program outcomes. In the discussion we return to consider how to increase access to yoga to older veterans based on these findings.

Methods

Study 1 participants were identified from VHA tumor registries. Eligible patients had head and neck, esophageal, gastric, or colorectal cancers and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed a face-to-face semistructured interview at 6, 12, and 18 months after their cancer diagnosis with a trained interviewer. Complete protocol methods, including nonresponder information, are described elsewhere.³¹

Questions about yoga were asked at the 12 month postdiagnosis interview. Participants were read the following: “Here is a list of services some patients use to recover from cancer. Please tell me if you have used any of these.” The list included yoga, physical therapy, occupational therapy, exercise, meditation, or massage therapy. Next participants were provided education about yoga via the following description: “Yoga is a practice of stress reduction and exercise with stretching, holding positions and deep breathing. For some, it may improve your sleep, energy, flexibility, anxiety, and pain. The postures are done standing, sitting, or lying down. If needed, it can be done all from a chair.” We then asked whether they would attend if yoga was offered at the VHA hospital (yes, no, maybe). Participants provided brief responses to 2 open-ended questions: (“If I came to a yoga class, I …”; and “Is there anything that might make you more likely to come to a yoga class?”) Responses were transcribed verbatim and entered into a database for qualitative analysis. Subsequently, participants completed standardized measures of health-related quality of life and beliefs about yoga as described below.

Study 2 participants were identified from VHA tumor registries and a cancer support group. Eligible patients had a diagnosis of cancer (any type except basil cell carcinoma) within the previous 3 years and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed face-to-face semistructured interviews with a trained interviewer before and after participation in an 8-week yoga group that met twice per week. Complete protocol methods are described elsewhere.¹⁶ This paper focuses on 28 of the 37 enrolled patients for whom we have complete pre- and postclass interview data. We previously reported on adaptations made to yoga in our pilot group of 14 individuals, who in this small sample did not show statistically significant changes in their quality of life from before to after the class.¹⁶ This analysis includes those 14 individuals and 14 who participated in additional classes, focusing on beliefs, which were not previously reported.

Measures

Participants reported their age, gender, ethnicity (Hispanic/Latino or not), race, and level of education. Information about the cancer diagnosis, American Joint Committee on Cancer (AJCC) cancer stage, and treatments was obtained from the medical record. The Physical Function and Anxiety Subscales from the Patient-Reported Outcomes Measurement Information System were used to measure health-related quality of life (HRQoL).^32-34 Items are rated on a Likert scale from 1 (not at all) to 5 (very much).

The Beliefs About Yoga Scale (BAYS) was used to measure beliefs about the outcomes of engaging in yoga.²⁸ The 11-item scale has 3 factors: expected health benefits (5 items), expected discomfort (3 items), and expected social norms (3 items). Items from the expected discomfort and expected social norms are reverse scored so that a higher score indicates more positive beliefs. To reduce participant burden, in study 1 we selected 1 item from each factor with high factor loadings in the original cross-validation sample.²⁸ It would improve my overall health (Benefit, factor loading = .89); I would have to be more flexible to take a class (Discomfort, factor loading = .67); I would be embarrassed in a class (Social norms, factor loading = .75). Participants in study 2 completed the entire 11-item scale. Items were summed to create subscales and total scales.

Analysis

Descriptive statistics were used in study 1 to characterize participants’ yoga experience and interest. Changes in interest pre- and posteducation were evaluated with χ² comparison of distribution. The association of beliefs about yoga with 3 levels of interest (yes, no, maybe) was evaluated through analysis of variance (ANOVA) comparing the mean score on the summed BAYS items among the 3 groups. The association of demographic (age, education, race) and clinical factors (AJCC stage, physical function) with BAYS was determined through multivariate linear regression.

For analytic purposes, due to small subgroup sample sizes we compared those who identified as non-Hispanic White adults to those who identified as African American/Hispanic/other persons. To further evaluate the relationship of age to yoga beliefs, we examined beliefs about yoga in 3 age groups (40-59 years [n = 24]; 60-69 years [n = 58]; 70-89 years [n = 28]) using ANOVA comparing the mean score on the summed BAYS items among the 3 groups. In study 2, changes in interest before and after the yoga program were evaluated with paired t tests and repeated ANOVA, with beliefs about yoga prior to class as a covariate. The association of demographic and clinical factors with BAYS was determined as in the first sample through multivariate linear regression, except the variable of race was not included due to small sample size (ie, only 3 individuals identified as persons of color).

Thematic analysis in which content-related codes were developed and subsequently grouped together was applied to the data of 110 participants who responded to the open-ended survey questions in study 1 to further illuminate responses to closed-ended questions.³⁵ Transcribed responses to the open-ended questions were transferred to a spreadsheet. An initial code book with code names, definitions, and examples was developed based on an inductive method by one team member (EA).³⁵ Initially, coding and tabulation were conducted separately for each question but it was noted that content extended across response prompts (eg, responses to question 2 “What might make you more likely to come?” were spontaneously provided when answering question 1), thus coding was collapsed across questions. Next, 2 team members (EA, KD) coded the same responses, meeting weekly to discuss discrepancies. The code book was revised following each meeting to reflect refinements in code names and definitions, adding newly generated codes as needed. The process continued until consensus and data saturation was obtained, with 90% intercoder agreement. Next, these codes were subjected to thematic analysis by 2 team members (EA, KD) combining codes into 6 overarching themes. The entire team reviewed the codes and identified 2 supra themes: positive beliefs or facilitators and negative beliefs or barriers.

Consistent with the concept of reflexivity in qualitative research, we acknowledge the influence of the research team members on the qualitative process.³⁶ The primary coding team (EA, KD) are both researchers and employees of Veterans Affairs Boston Healthcare System who have participated in other research projects involving veterans and qualitative analyses but are not yoga instructors or yoga researchers.

Results

Study 1

The sample of 110 military veterans was mostly male (99.1%) with a mean (SD) age of 64.9 (9.4) years (range, 41-88)(Table 1). The majority (70.9%) described their race/ethnicity as White, non-Hispanic followed by Black/African American (18.2%) and Hispanic (8.2%) persons; 50.0% had no more than a high school education. The most common cancer diagnoses were colorectal (50.9%), head and neck (39.1%), and esophageal and gastric (10.0%) and ranged from AJCC stages I to IV.

When first asked, the majority of participants (78.2%) reported that they were not interested in yoga, 16.4% reported they might be interested, and 5.5% reported they had tried a yoga class since their cancer diagnosis. In contrast, 40.9% used exercise, 32.7% used meditation, 14.5% used physical or occupational therapy, and 11.8% used massage therapy since their cancer diagnosis.

Study 2 Intervention Sample

This sample of 28 veterans was mostly male (96.4%) with a mean (SD) age of 69.2 (10.9) years (range, 57-87). The majority (89.3%) described their race as White, followed by Black/African American (10.7%); no participants self-identified in other categories for race/ethnicity. Twelve veterans (42.9%) had no more than a high school education. The most common cancer diagnosis was genitourinary (35.7%) and the AJCC stage ranged from I to IV.

We employed information learned in study 1 to enhance access in study 2. We mailed letters to 278 veterans diagnosed with cancer in the previous 3 years that provided education about yoga based on study 1 findings. Of 207 veterans reached by phone, 133 (64%) stated they were not interested in coming to a yoga class; 74 (36%) were interested, but 30 felt they were unable to attend due to obstacles such as illness or travel. Ultimately 37 (18%) veterans agreed and consented to the class, and 28 (14%) completed postclass surveys.

In multivariate regression, higher expected health benefits of yoga were associated with higher physical function, lower concern about expected discomfort was also associated with higher physical function as well as higher education; similarly, lower concern about expected social norms was associated with higher physical function. Age was not associated with any of the BAYS factors.

Beliefs about yoga improved from before to after class for all 3 domains with greater expected benefit and lower concerns about discomfort or social norms: expected benefit (mean difference, 5.3; t = 4.44, P < .001), expected discomfort (mean difference, 3.0; t = 4.92, P < .001), expected social norms (mean difference, 3.5; t = 4.38, P < .001). Physical function improved from before the class to afterwards (mean difference, 7.5; t = 3.97, P < .001) but there were no changes in anxiety (mean difference, 0.6; t = 0.76, P = .46). Beliefs about yoga moderated changes in physical function, such that those with higher beliefs experienced a greater improvement in physical function (F = 15.24, P < .001).

Discussion

Yoga is an effective clinical intervention for addressing some long-term adverse effects in cancer survivors, although the body of research focuses predominantly on middle aged, female, White, college-educated breast cancer survivors. There is no evidence to suggest yoga would be less effective in other groups, but it has not been extensively studied in survivors from diverse subgroups. Beliefs about yoga are a factor that may enhance interest in yoga interventions and research, and measures aimed at addressing potential beliefs and fears may capture information that can be used to support older cancer survivors in holistic health. The aims of this study were to examine beliefs about yoga in 2 samples of older cancer survivors who received VHA care. The main findings are (1) interest in yoga was initially low and lower than that of other complementary or exercise-based interventions, but increased when participants were provided brief education about yoga; (2) interest in yoga was associated with beliefs about yoga with qualitative comments illuminating these beliefs; (3) demographic characteristics (education, race) and physical function were associated with beliefs about yoga; and (4) positive beliefs about yoga increased following a brief yoga intervention and was associated with improvements in physical function.

Willingness to consider a class appeared to shift for some older veterans when they were presented brief information about yoga that explained what is involved, how it might help, and that it could be done from a chair if needed. These findings clearly indicated that when trying to enhance participation in yoga in clinical or research programs, it will be important that recruitment materials provide such information. This finding is consistent with the qualitative findings that reflected a lack of knowledge or skepticism about benefits of yoga among some participants. Given the finding that physical function was associated with beliefs about yoga and was also a prominent theme in qualitative analyses, when referring older veterans to yoga it may be useful to explicitly state that yoga may enhance some aspects of physical function and can be adapted for level of physical function or pain limitations. The finding that beliefs about yoga were associated with education also suggests that materials should be presented at all levels of education.

Age was not associated with beliefs about yoga in either study. Importantly, in a more detailed study 1 follow-up analysis, beliefs about yoga were equivalent for aged > 70 years compared with those aged 40 to 69 years. It is not entirely clear why older adults have been underrepresented in studies of yoga in cancer survivors. However, older adults are vastly underrepresented in clinical trials for many health conditions, even though they are more likely to experience many diseases, including cancer.³⁷ A new National Institutes of Health policy requires that individuals of all ages, including older adults, must be included in all human subjects research unless there are scientific reasons not to include them.³⁸ It is therefore imperative to consider strategies to address underrepresentation of older adults.

Limitations

These findings have several limitations. First, participants were homogeneous in age, gender, race/ethnicity and veteran status, which provides a window into this understudied population but limits generalizability and our ability to control across populations. Second, the sample size limited the ability to conduct subgroup and interaction analyses, such as examining potential differential effects of cancer type, treatment, and PTSD on yoga beliefs or to consider the relationship of yoga beliefs with changes in quality of life before and after the yoga intervention in study 2. Additionally, age was not associated with beliefs about yoga in these samples that of mostly older adults. We were able to compare middle-aged and older adults but could not compare beliefs about yoga to adults aged in their 20s and 30s. Last, our study excluded people with dementia and psychotic disorders. Further research is needed to examine yoga for older cancer survivors who have these conditions.

Conclusions

Education that specifically informs potential participants about yoga practice, potential modifications, and potential benefits, as well as adaptations to programs that address physical and logistical barriers may be useful in increasing access to and participation in yoga for older Veterans who are cancer survivors.

Results

Study 1

The sample of 110 military veterans was mostly male (99.1%) with a mean (SD) age of 64.9 (9.4) years (range, 41-88)(Table 1). The majority (70.9%) described their race/ethnicity as White, non-Hispanic followed by Black/African American (18.2%) and Hispanic (8.2%) persons; 50.0% had no more than a high school education. The most common cancer diagnoses were colorectal (50.9%), head and neck (39.1%), and esophageal and gastric (10.0%) and ranged from AJCC stages I to IV.

When first asked, the majority of participants (78.2%) reported that they were not interested in yoga, 16.4% reported they might be interested, and 5.5% reported they had tried a yoga class since their cancer diagnosis. In contrast, 40.9% used exercise, 32.7% used meditation, 14.5% used physical or occupational therapy, and 11.8% used massage therapy since their cancer diagnosis.

Study 2 Intervention Sample

This sample of 28 veterans was mostly male (96.4%) with a mean (SD) age of 69.2 (10.9) years (range, 57-87). The majority (89.3%) described their race as White, followed by Black/African American (10.7%); no participants self-identified in other categories for race/ethnicity. Twelve veterans (42.9%) had no more than a high school education. The most common cancer diagnosis was genitourinary (35.7%) and the AJCC stage ranged from I to IV.

We employed information learned in study 1 to enhance access in study 2. We mailed letters to 278 veterans diagnosed with cancer in the previous 3 years that provided education about yoga based on study 1 findings. Of 207 veterans reached by phone, 133 (64%) stated they were not interested in coming to a yoga class; 74 (36%) were interested, but 30 felt they were unable to attend due to obstacles such as illness or travel. Ultimately 37 (18%) veterans agreed and consented to the class, and 28 (14%) completed postclass surveys.

In multivariate regression, higher expected health benefits of yoga were associated with higher physical function, lower concern about expected discomfort was also associated with higher physical function as well as higher education; similarly, lower concern about expected social norms was associated with higher physical function. Age was not associated with any of the BAYS factors.

Beliefs about yoga improved from before to after class for all 3 domains with greater expected benefit and lower concerns about discomfort or social norms: expected benefit (mean difference, 5.3; t = 4.44, P < .001), expected discomfort (mean difference, 3.0; t = 4.92, P < .001), expected social norms (mean difference, 3.5; t = 4.38, P < .001). Physical function improved from before the class to afterwards (mean difference, 7.5; t = 3.97, P < .001) but there were no changes in anxiety (mean difference, 0.6; t = 0.76, P = .46). Beliefs about yoga moderated changes in physical function, such that those with higher beliefs experienced a greater improvement in physical function (F = 15.24, P < .001).

Discussion

Yoga is an effective clinical intervention for addressing some long-term adverse effects in cancer survivors, although the body of research focuses predominantly on middle aged, female, White, college-educated breast cancer survivors. There is no evidence to suggest yoga would be less effective in other groups, but it has not been extensively studied in survivors from diverse subgroups. Beliefs about yoga are a factor that may enhance interest in yoga interventions and research, and measures aimed at addressing potential beliefs and fears may capture information that can be used to support older cancer survivors in holistic health. The aims of this study were to examine beliefs about yoga in 2 samples of older cancer survivors who received VHA care. The main findings are (1) interest in yoga was initially low and lower than that of other complementary or exercise-based interventions, but increased when participants were provided brief education about yoga; (2) interest in yoga was associated with beliefs about yoga with qualitative comments illuminating these beliefs; (3) demographic characteristics (education, race) and physical function were associated with beliefs about yoga; and (4) positive beliefs about yoga increased following a brief yoga intervention and was associated with improvements in physical function.

Willingness to consider a class appeared to shift for some older veterans when they were presented brief information about yoga that explained what is involved, how it might help, and that it could be done from a chair if needed. These findings clearly indicated that when trying to enhance participation in yoga in clinical or research programs, it will be important that recruitment materials provide such information. This finding is consistent with the qualitative findings that reflected a lack of knowledge or skepticism about benefits of yoga among some participants. Given the finding that physical function was associated with beliefs about yoga and was also a prominent theme in qualitative analyses, when referring older veterans to yoga it may be useful to explicitly state that yoga may enhance some aspects of physical function and can be adapted for level of physical function or pain limitations. The finding that beliefs about yoga were associated with education also suggests that materials should be presented at all levels of education.

Age was not associated with beliefs about yoga in either study. Importantly, in a more detailed study 1 follow-up analysis, beliefs about yoga were equivalent for aged > 70 years compared with those aged 40 to 69 years. It is not entirely clear why older adults have been underrepresented in studies of yoga in cancer survivors. However, older adults are vastly underrepresented in clinical trials for many health conditions, even though they are more likely to experience many diseases, including cancer.³⁷ A new National Institutes of Health policy requires that individuals of all ages, including older adults, must be included in all human subjects research unless there are scientific reasons not to include them.³⁸ It is therefore imperative to consider strategies to address underrepresentation of older adults.

Limitations

These findings have several limitations. First, participants were homogeneous in age, gender, race/ethnicity and veteran status, which provides a window into this understudied population but limits generalizability and our ability to control across populations. Second, the sample size limited the ability to conduct subgroup and interaction analyses, such as examining potential differential effects of cancer type, treatment, and PTSD on yoga beliefs or to consider the relationship of yoga beliefs with changes in quality of life before and after the yoga intervention in study 2. Additionally, age was not associated with beliefs about yoga in these samples that of mostly older adults. We were able to compare middle-aged and older adults but could not compare beliefs about yoga to adults aged in their 20s and 30s. Last, our study excluded people with dementia and psychotic disorders. Further research is needed to examine yoga for older cancer survivors who have these conditions.

Conclusions

Education that specifically informs potential participants about yoga practice, potential modifications, and potential benefits, as well as adaptations to programs that address physical and logistical barriers may be useful in increasing access to and participation in yoga for older Veterans who are cancer survivors.

Yoga is an effective clinical intervention for cancer survivors. Studies indicate a wide range of benefits, including improvements in physical functioning, emotional well-being and overall quality of life.^1-7 Two-thirds of National Cancer Institute designated comprehensive cancer centers offer yoga on-site.⁸ Yoga is endorsed by the National Comprehensive Cancer Network and American Society of Clinical Oncology for managing symptoms, such as cancer-related anxiety and depression and for improving overall quality of life.^9,10

Although the positive effects of yoga on cancer patients are well studied, most published research in this area reports on predominantly middle-aged women with breast cancer.^11,12 Less is known about the use of yoga in other groups of cancer patients, such as older adults, veterans, and those from diverse racial or ethnic backgrounds. This gap in the literature is concerning considering that the majority of cancer survivors are aged 60 years or older, and veterans face unique risk factors for cancer associated with herbicide exposure (eg, Agent Orange) and other military-related noxious exposures.^13,14 Older cancer survivors may have more difficulty recovering from treatment-related adverse effects, making it especially important to target recovery efforts to older adults.¹⁵ Yoga can be adapted for older cancer survivors with age-related comorbidities, similar to adaptations made for older adults who are not cancer survivors but require accommodations for physical limitations.^16-20 Similarly, yoga programs targeted to racially diverse cancer survivors are associated with improved mood and well-being in racially diverse cancer survivors, but studies suggest community engagement and cultural adaptation may be important to address the needs of culturally diverse cancer survivors.^21-23

Yoga has been increasingly studied within the Veterans Health Administration (VHA) for treatment of posttraumatic stress disorder (PTSD) and has been found effective in reducing symptoms through the use of trauma-informed and military-relevant instruction as well as a military veteran yoga teacher.^24-26 This work has not targeted older veterans or cancer survivors who may be more difficult to recruit into such programs, but who would nevertheless benefit.

Clinically, the VHA whole health model is providing increased opportunities for veterans to engage in holistic care including yoga.²⁷ Resources include in-person yoga classes (varies by facility), videos, and handouts with practices uniquely designed for veterans or wounded warriors. As clinicians increasingly refer veterans to these programs, it will be important to develop strategies to engage older veterans in these services.

One important strategy to enhancing access to yoga for older veterans is to consider beliefs about yoga. Beliefs about yoga or general expectations about the outcomes of yoga may be critical to consider in expanding access to yoga in underrepresented groups. Beliefs about yoga may include beliefs about yoga improving health, yoga being difficult or producing discomfort, and yoga involving specific social norms.²⁸ For example, confidence in one’s ability to perform yoga despite discomfort predicted class attendance and practice in a sample of 32 breast cancer survivors.²⁹ Relatedly, positive beliefs about the impact of yoga on health were associated with improvements in mood and quality of life in a sample of 66 cancer survivors.³⁰

The aim of this study was to examine avenues to enhance access to yoga for older veterans, including those from diverse backgrounds, with a focus on the role of beliefs. In the first study we investigate the association between beliefs about and barriers to yoga in a group of older cancer survivors, and we consider the role of demographic and clinical variables in such beliefs and how education may alter beliefs. In alignment with the whole health model of holistic health, we posit that yoga educational materials and resources may contribute to yoga beliefs and work to decrease these barriers. We apply these findings in a second study that enrolled older veterans in yoga and examining the impact of program participation on beliefs and the role of beliefs in program outcomes. In the discussion we return to consider how to increase access to yoga to older veterans based on these findings.

Methods

Study 1 participants were identified from VHA tumor registries. Eligible patients had head and neck, esophageal, gastric, or colorectal cancers and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed a face-to-face semistructured interview at 6, 12, and 18 months after their cancer diagnosis with a trained interviewer. Complete protocol methods, including nonresponder information, are described elsewhere.³¹

Questions about yoga were asked at the 12 month postdiagnosis interview. Participants were read the following: “Here is a list of services some patients use to recover from cancer. Please tell me if you have used any of these.” The list included yoga, physical therapy, occupational therapy, exercise, meditation, or massage therapy. Next participants were provided education about yoga via the following description: “Yoga is a practice of stress reduction and exercise with stretching, holding positions and deep breathing. For some, it may improve your sleep, energy, flexibility, anxiety, and pain. The postures are done standing, sitting, or lying down. If needed, it can be done all from a chair.” We then asked whether they would attend if yoga was offered at the VHA hospital (yes, no, maybe). Participants provided brief responses to 2 open-ended questions: (“If I came to a yoga class, I …”; and “Is there anything that might make you more likely to come to a yoga class?”) Responses were transcribed verbatim and entered into a database for qualitative analysis. Subsequently, participants completed standardized measures of health-related quality of life and beliefs about yoga as described below.

Study 2 participants were identified from VHA tumor registries and a cancer support group. Eligible patients had a diagnosis of cancer (any type except basil cell carcinoma) within the previous 3 years and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed face-to-face semistructured interviews with a trained interviewer before and after participation in an 8-week yoga group that met twice per week. Complete protocol methods are described elsewhere.¹⁶ This paper focuses on 28 of the 37 enrolled patients for whom we have complete pre- and postclass interview data. We previously reported on adaptations made to yoga in our pilot group of 14 individuals, who in this small sample did not show statistically significant changes in their quality of life from before to after the class.¹⁶ This analysis includes those 14 individuals and 14 who participated in additional classes, focusing on beliefs, which were not previously reported.

Measures

Participants reported their age, gender, ethnicity (Hispanic/Latino or not), race, and level of education. Information about the cancer diagnosis, American Joint Committee on Cancer (AJCC) cancer stage, and treatments was obtained from the medical record. The Physical Function and Anxiety Subscales from the Patient-Reported Outcomes Measurement Information System were used to measure health-related quality of life (HRQoL).^32-34 Items are rated on a Likert scale from 1 (not at all) to 5 (very much).

The Beliefs About Yoga Scale (BAYS) was used to measure beliefs about the outcomes of engaging in yoga.²⁸ The 11-item scale has 3 factors: expected health benefits (5 items), expected discomfort (3 items), and expected social norms (3 items). Items from the expected discomfort and expected social norms are reverse scored so that a higher score indicates more positive beliefs. To reduce participant burden, in study 1 we selected 1 item from each factor with high factor loadings in the original cross-validation sample.²⁸ It would improve my overall health (Benefit, factor loading = .89); I would have to be more flexible to take a class (Discomfort, factor loading = .67); I would be embarrassed in a class (Social norms, factor loading = .75). Participants in study 2 completed the entire 11-item scale. Items were summed to create subscales and total scales.

Analysis

Descriptive statistics were used in study 1 to characterize participants’ yoga experience and interest. Changes in interest pre- and posteducation were evaluated with χ² comparison of distribution. The association of beliefs about yoga with 3 levels of interest (yes, no, maybe) was evaluated through analysis of variance (ANOVA) comparing the mean score on the summed BAYS items among the 3 groups. The association of demographic (age, education, race) and clinical factors (AJCC stage, physical function) with BAYS was determined through multivariate linear regression.

For analytic purposes, due to small subgroup sample sizes we compared those who identified as non-Hispanic White adults to those who identified as African American/Hispanic/other persons. To further evaluate the relationship of age to yoga beliefs, we examined beliefs about yoga in 3 age groups (40-59 years [n = 24]; 60-69 years [n = 58]; 70-89 years [n = 28]) using ANOVA comparing the mean score on the summed BAYS items among the 3 groups. In study 2, changes in interest before and after the yoga program were evaluated with paired t tests and repeated ANOVA, with beliefs about yoga prior to class as a covariate. The association of demographic and clinical factors with BAYS was determined as in the first sample through multivariate linear regression, except the variable of race was not included due to small sample size (ie, only 3 individuals identified as persons of color).

Thematic analysis in which content-related codes were developed and subsequently grouped together was applied to the data of 110 participants who responded to the open-ended survey questions in study 1 to further illuminate responses to closed-ended questions.³⁵ Transcribed responses to the open-ended questions were transferred to a spreadsheet. An initial code book with code names, definitions, and examples was developed based on an inductive method by one team member (EA).³⁵ Initially, coding and tabulation were conducted separately for each question but it was noted that content extended across response prompts (eg, responses to question 2 “What might make you more likely to come?” were spontaneously provided when answering question 1), thus coding was collapsed across questions. Next, 2 team members (EA, KD) coded the same responses, meeting weekly to discuss discrepancies. The code book was revised following each meeting to reflect refinements in code names and definitions, adding newly generated codes as needed. The process continued until consensus and data saturation was obtained, with 90% intercoder agreement. Next, these codes were subjected to thematic analysis by 2 team members (EA, KD) combining codes into 6 overarching themes. The entire team reviewed the codes and identified 2 supra themes: positive beliefs or facilitators and negative beliefs or barriers.

Consistent with the concept of reflexivity in qualitative research, we acknowledge the influence of the research team members on the qualitative process.³⁶ The primary coding team (EA, KD) are both researchers and employees of Veterans Affairs Boston Healthcare System who have participated in other research projects involving veterans and qualitative analyses but are not yoga instructors or yoga researchers.

Results

Study 1

The sample of 110 military veterans was mostly male (99.1%) with a mean (SD) age of 64.9 (9.4) years (range, 41-88)(Table 1). The majority (70.9%) described their race/ethnicity as White, non-Hispanic followed by Black/African American (18.2%) and Hispanic (8.2%) persons; 50.0% had no more than a high school education. The most common cancer diagnoses were colorectal (50.9%), head and neck (39.1%), and esophageal and gastric (10.0%) and ranged from AJCC stages I to IV.

When first asked, the majority of participants (78.2%) reported that they were not interested in yoga, 16.4% reported they might be interested, and 5.5% reported they had tried a yoga class since their cancer diagnosis.

Health care has been dramatically transformed and influenced by medical and technological advances, insurance companies, state and federal legislation, and medical ethics. Amid these changes, including crises such as the ongoing coronavirus pandemic, earning the trust of patients to care for their mental and physical health remains a priority and a privilege.

It is troubling that federal health care agencies, in addition to hospitals, clinics, pharmacies, insurance companies, and administrators, often use the term provider when referring to clinicians on the multidisciplinary health care treatment team, which has become the predominant model for health care delivery. The word provider does not originate in the health care arena but from the world of commerce and contains no reference to professionalism or therapeutic relationships.¹ Therefore, it should be replaced with more appropriate terminology that acknowledges clinicians’ roles and expertise and values our unique relationship with patients.

Why Is Provider a Problem?

First, the origin of the term provider is deplorable. During its ascent to power in the 1930s, the Nazi Party promoted the devaluation and exclusion of Jews in German society, including the medical community. Due to its eugenics campaign, the Nazi Party first targeted pediatrics, a specialty in which nearly half of its practitioners were Jewish.² Beginning with female pediatricians, all Jewish physicians were redesignated as Behandler (provider) instead of Arzt (doctor).² This is the first documented demeaning of physicians as providers in modern history. Jewish doctors were soon restricted to treating only Jewish patients and were further persecuted during the Holocaust. Knowing this background, what health care organization would use a term once associated with Nazi ideology?³

Second, using provider changes the treatment relationship. The nomenclature shift in the United States also seems to have originated in political and legislative circles. Although the reasons for this shift are unclear, the terminology became more pervasive after the government first used the term provider in Title XIX of the 1965 Social Security Amendments that established Medicare and Medicaid. Paydarfar and Schwartz noted it was used “in the sense of a contractor being paid for delivering any health-related products and services.”⁴ Ironically, a 1967 medical student health organization grant proposal discussed the role of a patient advocate in facilitating communication between “health care provider and patient.”⁵ A journalist for the New York Times used the word to describe a 1970 New York Senate debate surrounding the sale of Medicaid bills to collection agencies, but it is unclear whether the senators themselves used the term.⁶ Provider was later used in the National Health Planning and Resource Development Act of 1974.⁷

Ultimately, the adaptation of this terminology led to medicine being thought of only as a business, a commoditization of care, and reinforced by referring to patients as consumers, clients, or customers.³ This terminology suggests that the clinician-patient relationship is a commercial transaction based on a market concept where patients are consumers to be serviced.^1,8 Emphasis is placed on following algorithms and treating symptoms rather than patients.⁹ Despite a goal of minimizing cost, a mismatched referral to a provider may actually compromise patient safety and cost-effectiveness due to missed diagnoses or excessive diagnostic testing.¹⁰

In addition to government, other nonclinical entities (eg, insurance companies, advocacy groups) and some clinicians may prefer the generic term provider. Besides health care commoditization, reasons may include convenience, simplifying health care nomenclature, or removing distinctions among health care professionals to reduce costs and/or increase autonomy.

However, our value as health care professionals is not simply what we can “provide.”¹¹ We seek to know patients as people, putting their needs ahead of ours.¹ We serve as confidants and advocates and not merely providers of medications, tests, or procedures.¹¹ This personalized nature of health care depends on trust and professionalism rather than dispassionate delivery of commoditized services.¹ Using traditional terminology acknowledges the true nature of the treatment relationship—one that is established not on market concepts but on medical ethics of autonomy, justice, beneficence, and nonmaleficence.

Third, provider is inaccurate and potentially disrespectful and harmful. The word doctor is derived from Latin doctus or docere, meaning to teach or instruct—a valued function in our interactions with patients, families, students, and colleagues.^12,13 In contrast, provider refers to commercial transactions or the provision of shelter, food, and love within families and communities.^1,14

Although there are no studies assessing the impact of this terminology on individual clinicians, the term provider may have a negative impact on both individual clinicians and on the health care system. Health care professionals may feel they are being disrespected by being portrayed as dispensers of services rather than as individuals.^13,15 Furthermore, provider does not acknowledge the specialized training and qualifications of multidisciplinary treatment team members. The historical and theoretical foundation, degrees awarded, and scopes of practice for physicians, physician assistants, nurse practitioners, dentists, psychologists, optometrists, physical therapists, or social workers are different yet valuable, and their expertise and accomplishment should be recognized.

The use of this term has potential for causing moral injury and reduced self-worth, sense of purpose, and meaning in our daily work; this could threaten satisfaction and commitment and lead to demoralization and burnout.^1,16 It may impair effective team dynamics, as it makes no reference to professional values and may lead patients and clinicians to place lower value on professionalism and conduct.¹⁰ It may negatively impact primary care specialties by propagating the connotation that primary care is simple care and promoting low compensation, lagging recruitment, and diminished respect.¹⁰ Finally, it is detrimental to patients by changing the nature of the relationship and failing to evoke the compassion and support that sick people (that is, patients) need and deserve.³

Last, use of this term can mislead patients. By law, a health care provider is defined as “a doctor of medicine or osteopathy who is authorized to practice medicine or surgery… or any other person determined by the Secretary [of Labor] to be capable of providing health care services,” which includes podiatrists, dentists, clinical psychologists, optometrists, chiropractors, nurse practitioners, nurse-midwives, clinical social workers, and physician assistants.¹⁷

When clinicians are categorized as providers rather than by their degrees and roles/responsibilities, patients may assume that all team members have equal training, interchangeable skills, and uniform expertise and knowledge and may conclude they can receive the same level of care from anyone.^8,10 Potential for confusion is increased by the nearly ubiquitous white laboratory coat in clinical settings and doctoral degrees attainable in different health care disciplines (eg, medicine, nursing, psychology, pharmacy, physical therapy). Patients deserve to know who does what on the team of professionals who care for them and may not be fully informed when requesting or receiving treatment if they are not provided important information, such as a clinician’s title, training, and scope of practice.^8,16

Reversing the Trend 

Increasing awareness among patients, their families, health professions students, and health care colleagues and administrators of the importance of traditional nomenclature is a first step in reversing this trend or mitigating its impact. If an overarching generic term is required, then health care professional, clinician, or practitioner are preferred.^10,12 Fifteen years ago, the Southern California Permanente Medical Group prohibited the use of the word provider to describe physicians, and its editorial style deemed it cold and institutional.¹⁶ Many, but not all, state, regional, or national medical associations and journals avoid provider in their names or titles.

I am encouraged that this journal—drawing its audience from several government health care agencies—is named Federal Practitioner rather than Federal Provider. This is reasonable and accurate, as practitioner refers to the practice of a profession, usually associated with health care.

I hope other professions can resist this trend. Lawyers are not considered legal aid providers, and teachers are not called knowledge providers.³ We do not refer to airline pilots as air transportation providers or musicians as instrument-playing melody providers. Many veterans likely would be offended if they were referred to as Constitution support and defense providers rather than by the military branch-specific titles that they earned through dedication, training, and sacrifice. The individuals in these examples demonstrate commitment to representing clients, educating students, flying passengers, playing instruments, or ensuring national defense. As health care professionals, our commitment to treating patients is equally important.⁴

Language matters when it comes to people feeling respected and achieving their full potential.¹ I encourage government health care agencies to stop referring to us as providers and resume using traditional nomenclature. This will demonstrate genuine respect for us, transparency for the patients we serve, and recognition that caring for the sick is a calling, not a commodity.

Second, using provider changes the treatment relationship. The nomenclature shift in the United States also seems to have originated in political and legislative circles. Although the reasons for this shift are unclear, the terminology became more pervasive after the government first used the term provider in Title XIX of the 1965 Social Security Amendments that established Medicare and Medicaid. Paydarfar and Schwartz noted it was used “in the sense of a contractor being paid for delivering any health-related products and services.”⁴ Ironically, a 1967 medical student health organization grant proposal discussed the role of a patient advocate in facilitating communication between “health care provider and patient.”⁵ A journalist for the New York Times used the word to describe a 1970 New York Senate debate surrounding the sale of Medicaid bills to collection agencies, but it is unclear whether the senators themselves used the term.⁶ Provider was later used in the National Health Planning and Resource Development Act of 1974.⁷

Ultimately, the adaptation of this terminology led to medicine being thought of only as a business, a commoditization of care, and reinforced by referring to patients as consumers, clients, or customers.³ This terminology suggests that the clinician-patient relationship is a commercial transaction based on a market concept where patients are consumers to be serviced.^1,8 Emphasis is placed on following algorithms and treating symptoms rather than patients.⁹ Despite a goal of minimizing cost, a mismatched referral to a provider may actually compromise patient safety and cost-effectiveness due to missed diagnoses or excessive diagnostic testing.¹⁰

In addition to government, other nonclinical entities (eg, insurance companies, advocacy groups) and some clinicians may prefer the generic term provider. Besides health care commoditization, reasons may include convenience, simplifying health care nomenclature, or removing distinctions among health care professionals to reduce costs and/or increase autonomy.

However, our value as health care professionals is not simply what we can “provide.”¹¹ We seek to know patients as people, putting their needs ahead of ours.¹ We serve as confidants and advocates and not merely providers of medications, tests, or procedures.¹¹ This personalized nature of health care depends on trust and professionalism rather than dispassionate delivery of commoditized services.¹ Using traditional terminology acknowledges the true nature of the treatment relationship—one that is established not on market concepts but on medical ethics of autonomy, justice, beneficence, and nonmaleficence.

Third, provider is inaccurate and potentially disrespectful and harmful. The word doctor is derived from Latin doctus or docere, meaning to teach or instruct—a valued function in our interactions with patients, families, students, and colleagues.^12,13 In contrast, provider refers to commercial transactions or the provision of shelter, food, and love within families and communities.^1,14

Although there are no studies assessing the impact of this terminology on individual clinicians, the term provider may have a negative impact on both individual clinicians and on the health care system. Health care professionals may feel they are being disrespected by being portrayed as dispensers of services rather than as individuals.^13,15 Furthermore, provider does not acknowledge the specialized training and qualifications of multidisciplinary treatment team members. The historical and theoretical foundation, degrees awarded, and scopes of practice for physicians, physician assistants, nurse practitioners, dentists, psychologists, optometrists, physical therapists, or social workers are different yet valuable, and their expertise and accomplishment should be recognized.

The use of this term has potential for causing moral injury and reduced self-worth, sense of purpose, and meaning in our daily work; this could threaten satisfaction and commitment and lead to demoralization and burnout.^1,16 It may impair effective team dynamics, as it makes no reference to professional values and may lead patients and clinicians to place lower value on professionalism and conduct.¹⁰ It may negatively impact primary care specialties by propagating the connotation that primary care is simple care and promoting low compensation, lagging recruitment, and diminished respect.¹⁰ Finally, it is detrimental to patients by changing the nature of the relationship and failing to evoke the compassion and support that sick people (that is, patients) need and deserve.³

Last, use of this term can mislead patients. By law, a health care provider is defined as “a doctor of medicine or osteopathy who is authorized to practice medicine or surgery… or any other person determined by the Secretary [of Labor] to be capable of providing health care services,” which includes podiatrists, dentists, clinical psychologists, optometrists, chiropractors, nurse practitioners, nurse-midwives, clinical social workers, and physician assistants.¹⁷

When clinicians are categorized as providers rather than by their degrees and roles/responsibilities, patients may assume that all team members have equal training, interchangeable skills, and uniform expertise and knowledge and may conclude they can receive the same level of care from anyone.^8,10 Potential for confusion is increased by the nearly ubiquitous white laboratory coat in clinical settings and doctoral degrees attainable in different health care disciplines (eg, medicine, nursing, psychology, pharmacy, physical therapy). Patients deserve to know who does what on the team of professionals who care for them and may not be fully informed when requesting or receiving treatment if they are not provided important information, such as a clinician’s title, training, and scope of practice.^8,16

Reversing the Trend 

Increasing awareness among patients, their families, health professions students, and health care colleagues and administrators of the importance of traditional nomenclature is a first step in reversing this trend or mitigating its impact. If an overarching generic term is required, then health care professional, clinician, or practitioner are preferred.^10,12 Fifteen years ago, the Southern California Permanente Medical Group prohibited the use of the word provider to describe physicians, and its editorial style deemed it cold and institutional.¹⁶ Many, but not all, state, regional, or national medical associations and journals avoid provider in their names or titles.

I am encouraged that this journal—drawing its audience from several government health care agencies—is named Federal Practitioner rather than Federal Provider. This is reasonable and accurate, as practitioner refers to the practice of a profession, usually associated with health care.

I hope other professions can resist this trend. Lawyers are not considered legal aid providers, and teachers are not called knowledge providers.³ We do not refer to airline pilots as air transportation providers or musicians as instrument-playing melody providers. Many veterans likely would be offended if they were referred to as Constitution support and defense providers rather than by the military branch-specific titles that they earned through dedication, training, and sacrifice. The individuals in these examples demonstrate commitment to representing clients, educating students, flying passengers, playing instruments, or ensuring national defense. As health care professionals, our commitment to treating patients is equally important.⁴

Language matters when it comes to people feeling respected and achieving their full potential.¹ I encourage government health care agencies to stop referring to us as providers and resume using traditional nomenclature. This will demonstrate genuine respect for us, transparency for the patients we serve, and recognition that caring for the sick is a calling, not a commodity.

Health care has been dramatically transformed and influenced by medical and technological advances, insurance companies, state and federal legislation, and medical ethics. Amid these changes, including crises such as the ongoing coronavirus pandemic, earning the trust of patients to care for their mental and physical health remains a priority and a privilege.

It is troubling that federal health care agencies, in addition to hospitals, clinics, pharmacies, insurance companies, and administrators, often use the term provider when referring to clinicians on the multidisciplinary health care treatment team, which has become the predominant model for health care delivery. The word provider does not originate in the health care arena but from the world of commerce and contains no reference to professionalism or therapeutic relationships.¹ Therefore, it should be replaced with more appropriate terminology that acknowledges clinicians’ roles and expertise and values our unique relationship with patients.

Why Is Provider a Problem?

First, the origin of the term provider is deplorable. During its ascent to power in the 1930s, the Nazi Party promoted the devaluation and exclusion of Jews in German society, including the medical community. Due to its eugenics campaign, the Nazi Party first targeted pediatrics, a specialty in which nearly half of its practitioners were Jewish.² Beginning with female pediatricians, all Jewish physicians were redesignated as Behandler (provider) instead of Arzt (doctor).² This is the first documented demeaning of physicians as providers in modern history. Jewish doctors were soon restricted to treating only Jewish patients and were further persecuted during the Holocaust. Knowing this background, what health care organization would use a term once associated with Nazi ideology?³

It is a time of significant change as the Military Health System (MHS) transitions to the purview of the Defense Health Agency (DHA). Additionally, the landscape of combat is ever changing, and military medicine needs to evolve to ensure that the lessons learned are utilized to optimize care of the war fighters. The purpose of this review is to evaluate the available literature on existing operational medicine curriculums and make recommendations to restructure current military medicine training to produce operationally prepared clinicians who are informed in operationally focused research principles.

Operational Medicine

Before diving into the importance of creating a curriculum and investing in training for scholarly activity proficiency, operational medicine needs to be defined. It can be defined as medical care provided in an austere environment with limited resources and possibly under hostile conditions. Another way to look at operational medicine is as the evaluation of normal human physiology and pathology under abnormal conditions. The mission set of each of the services is unique. The Marines and Army may operate forward past the wire vulnerable to the environment, gunfire, and improvised explosive devices, remote from fixed medical facilities. The Navy has divers exposed to the risks of decompression sickness. The Air Force has pilots exposed to altitude changes and strains of G-forces during flight. Locations vary from cold high-altitude mountainous regions to high-temperature desolate deserts. Many times, medical practitioners may be remotely stationed, far from specialty or immediate definitive care. Patient care may consist of low-acuity management of individual patients in sick call to mass casualty events where patient numbers and morbidity may outstrip available resources, making the difficult task of triage necessary.

Despite the challenges of being a uniformed physician, the benefits of being embedded is a better understanding of the roles and capability of the unit. Military physicians need to have the unique knowledge of the type of injuries sustained in that particular theater of war, such as differentiating between the trauma pattern and care required for blast injuries vs high-velocity missiles. There are also chemical, biologic, radiologic, and nuclear threats that military physicians need to recognize. Much of what disables a military fighting force is not a direct relationship to combat-related injuries; however, entire units have been taken down by infectious diarrhea or trench foot. There is also a need for familiarity of the infections and parasitology endemic to the particular theater with the aim of implementation of prevention whenever possible.

Military medicine does not fit in any box. Military physicians need to know the job requirements of various specialties, including elements of occupational medicine, such as aircrew piloting high-performance fighters or ground troops fully loaded with body armor and 80-lb backpacks. There are musculoskeletal injuries from the stressors of various military occupations. Working around weaponry and contact with hostile forces will create scenarios requiring emergent and critical care. In addition to physical injuries, there is the mental strain of combat with the risk of imminent personal injury, the guilt of survivorship, dealing with the scars and permanent physical damage of combat, and prolonged separation from family and other support systems.

The National Defense Authorization Act 2017 mandated the establishment of a standardized process to oversee all military graduate medical education (GME) programs with the goal of ensuring medical operational readiness.¹ This is no small task with > 3000 residents in more than 70 specialties, comprising approximately 12% of US residents.^1,2 Presently, 26 to 32% of the medical corps is enrolled in full-time training compared with 12% of the total force.² With significant time and resources expended during this period, it is vital to maximize the potential of the training.

Literature Review

A literature review was performed, evaluating historical precedence of specialized military medical training and research as well as current operational curriculums. Literature search was conducted in the PubMed and Uniformed Services University (USU) Learning Resource databases using the terms “operational medicine curriculum,” “military medicine curriculum,” “operational medicine training,” “military medicine training,” “operational medicine research,” and “military medicine research,” and included all articles from 1997 to 2020. Inclusion criteria included studies that detailed military medicine training programs and/or outcomes. The source types used in this research project included peer-reviewed journal publications—both review articles and original research—from medical and military journals. The citations of these articles were also reviewed for additional usable publications. Secondary sources included official reports and studies by the RAND Corporation, the US Government Accountability Office, and the Institute for Defense Analysis (IDA). Due to lack of literature on the topic, other sources such as talking papers, letters, and formal presentations from subject matter experts were included to showcase the current state and gaps on this topic. Key findings from peer-reviewed publications are presented in Table 1.

Overall, the literature review showed that longitudinal deliberately mapped out curriculums can be well integrated into the existing medical curriculum.³ The military medicine course topics include environmental medicine, applied field medicine, combat casualty care, medical support planning, mass casualty incident preparation, and military-focused problem solving, decision making, and leadership.⁴

One 1997 study looked at the degree of implementation of military unique curriculum in 18 family medicine residencies. Only 30% of residents stated that their program had a specific operational medicine curriculum.5 Salerno and colleagues surveyed current residents and recently graduated internal medicine physicians at 14 facilities in the Army, Air Force, and Navy to determine confidence level with military medicine. More than half did not feel ready to practice deployment medicine; just 19% felt comfortable treating nuclear, biologic, and chemical warfare injuries; and 32% felt unfamiliar with the command and administrative duties. A subgroup analysis showed that USU graduates felt more prepared in these areas compared with civilian program graduates.6 Additional studies showed perceived smoother transition in the first active-duty tour after participation in an operational curriculum.⁷

In addition to in-program training, other options include operational rotations offsite and military courses conducted outside the GME program.¹² Some of these courses may include just-in-time training such as expeditionary medical support system training prior to scheduled deployments. Examples of experiential training are listed in Table 3.

Critical Analysis 

Current gaps were identified in the military medicine training pipeline’s operational medicine curriculum and research programs. The analysis looked at specific components that make the operational medicine curriculum and research unique as well as current readiness goals, to determine how to best align both to meet the mission requirements. Some factors considered included efficiency, cost, program portability, duplication minimization, retention, and sustainability.

Efficiency

A well-created curriculum that meets objectives will require more than an assigned rotation and a few lectures. The most successful ones in the literature review were the ones that were deliberately planned and longitudinal, such as the ones at USU that combined a mixture of classroom and field exercises over the course of 4 years.^4,8 In that way, the curriculum may not be considered time efficient, but if integrated well into the already existing medical training, the production of military physicians who are mission ready upon graduation—ready to serve as military medical leaders and deploy—will be invaluable.

Cost Comparison

Due to the associated overhead of running a training platform and the additional hours of operational training, military GME is more expensive initially compared with civilian outsourcing. In USU, for example, there is an additional 700 hours of operational curriculum alone. This cost difference more than doubles the cost of a USU education vs a Health Professional Scholarship Program (HPSP) scholarship at a civilian medical school. However, a causal analysis performed by the IDA to determine value basis noted that USU graduates deploy almost 3 times as much and serve 6 years longer on active duty.³

After graduating medical school through either accession source, physicians complete specialization training in a GME program. The IDA study noted an average $12,000 increased cost of military GME compared with civilian programs. The analysis included resident compensation and overhead costs of running the program as well as the net cost, which also accounted for resident productivity and workload by training in a military facility.³ Calculations due to mandated budget cuts estimated cost savings of closing the military medical school at < $100 million while significantly impacting the military physician pipeline and operational research output.³

Duplication of Effort

There are already established training programs such as Tactical Combat Casualty Care (TCCC) that could be incorporated into the curriculum to avoid expending additional resources to recreate the wheel. USU has a validated operational training curriculum and may be able to make opportunities available for outside trainees to participate in some of its military-unique training and leadership exercises. Other ways to decrease duplication of effort and improve cost efficiency include focusing on the creation of an academic health system (AHS) and consolidating similar programs to conserve resources. Increasing existing military program sizes will not only ensure the continuation of the military medicine pipeline, but will spread overhead costs over a larger cohort, decrease costs of civilian outsourcing, and ensure the less tangible benefits of military cultural exposure early in trainees’ careers. For example, increasing the class size of USU by 30 students actually reduces the cost per student to $239,000 per year from $253,000, while decreasing the need for HPSP accessions training in civilian programs, making the endeavor overall cost neutral.³

Program Portability

The operational medicine residency has proved that an operational curriculum can be remotely managed and reproduced at a variety of residency specialties.¹² Remote education could be developed and distributed throughout the MHS, such as the proposed USU course Military Medicine and Leadership course.3 Centralized training programs like Global Medicine and C-STARS could be scheduled TDYs during the medical training calendar.

Retention

The military medical school, USU, is the largest military medicine accession source. An IDA report notes that retention of USU graduates is 15.2 years compared with 9.2 years served by civilian trainees. Due to the longevity in service, USU graduates also make up more than 25% of military medical leadership.4 The long-term outcome study that looked at the past 40 years of USU graduates observed that over 70% of graduates served until retirement eligibility and are overrepresented in special operations units.3,13 While some of this longevity may be attributed to the longer USU service contracts, military GME graduates were still noted to be 4 times more likely to commit to a multiyear service contract.¹⁴ A RAND study on the retention of military physicians in the Army, Air Force, and Navy noted that overall retention increased throughout all the services for physicians who went through the military GME pipeline.¹⁵ Conversely, civilian GME training was associated with a 45% chance in leaving active duty.¹⁶

It is theorized that early military acculturation during training increases the likelihood of instilling a sense of mission. Being involved in military GME on the teaching side also showed increased retention rates for 63% of survey respondents.¹⁷ Reduced burnout and increased work satisfaction for those involved in military GME was noted on another faculty satisfaction survey.¹⁷

Sustainability

Programs like USU, which have been around for decades, and the newer operational residency program evolving since 2013 have shown sustainability.^4,11 Dissemination of proven curriculums as well as centralization of already validated training programs can help standardize operational medical training throughout the MHS. In order to flourish at individual programs, the faculty need to be well versed in a train the trainer model and have institutional support. The ability to engage with the line at individual locations may be a factor as well.¹⁸ In regard to research, once residents are taught the principles of scholarly activity, they will have the tools to continue operational medicine research advancements and mentoring students.

Discussion

The 2020 NDAA recommends the establishment of an AHS.3 This step will create a culture of military medical readiness from the top down as congressional mandates push reorganization of the MHS, including military GME programs. An overall restructuring of military medicine will require prioritization of resources toward operational requirements vs the historic significant division of attention to beneficiary care that has caused a lack of unity of effort and additional strain on an already heavily tasked medical force. The changes in military GME are just one aspect of that. It is vital to look at the restructuring with a comprehension of the unique challenges of combat health rather than only from an in-garrison, hospital-based aspect.¹⁹ Benefits of having a military medicine AHS include opportunities to share resources and successful business models as well as foster interdisciplinary teamwork and partnerships with civilian health care facilities and research institutions as a force multiplier.¹⁹

There has been recent discussion about budget cuts, including shutting down USU and military GME and transitioning all training to civilian programs to be cost-effective.⁴ If this were to happen, it would be a step backward from the goal of operational readiness. Maintaining US Department of Defense (DoD) control of the military medicine pipeline has innumerable benefits, including built-in mentorship from operationally-seasoned faculty, military leadership development, proficiency in MHS systems, open communication between GME programs and DoD, and curriculum control to ensure focus on readiness.²⁰ Military GME programs are also a significant production source of military-related scholarly activity. Over fiscal year 2017/2018, 63% of the publications out of the San Antonio Uniformed Services Health Education Consortium—the largest Air Force GME platform and second largest multiservice GME platform—involved military relevant medical topics.¹⁷ Much of the volume of operational research as well as the relevant skills learned and future innovations secondary to conducting this research would be lost if military GME did not exist.^17,21

Practically speaking, military GME provides the majority of the military medicine accessions. For example, a presentation by the Air Force Chief of Physician Education noted that the total military GME pipeline included 2875 students, but direct physician access averaged only 20 physicians a year.²² Even if the decision was made to defer to civilian education, capacity does not exist in civilian GME programs. This is worsened by the increased competitiveness of the GME match with the proliferation of medical schools without concurrent increase in residency spots. The 2018 National Resident Matching Program noted that there were more than 37,103 US and foreign applicants for only 33,000 residency positions, leaving many US applicants unmatched.¹⁷ It is doubtful that the civilian GME programs would be able to absorb the influx of military residents, affecting both the military and civilian medicine pipelines. As a secondary effect, the military treatment centers that house the military GME programs would have to close, with surrounding civilian medical facilities also likely unable to absorb the sudden influx of patients and residents losing the intangible benefits of caring for a military population.¹⁵ This was even recognized by the civilian president of the Accreditation Council for Graduate Medical Education:

Military physicians must be trained in the systems of care that are operative in military medicine, which is significantly unlike civilian medicine in many ways. It is often practiced in circumstances that are not seen in civilian medicine, within care structures that are not encountered in American medical practice… Military medicine has advanced research into the care of individuals suffering traumatic injury, critical care, rehabilitation medicine, prosthetics, psychiatric care of those traumatized, and closed head injury, to name a just a few. The sacrifices of our active military demand these advances, and the American Public benefit from these advances.²¹

Where deficiencies exist in military GME, it is possible to use the growing military-civilian training institution partnerships. Two prime examples are the just-in-time deployment training done with civilian trauma facilities by the Air Force Center for the Sustainment of Trauma Readiness Skills and the Air Force Special Operations Surgical Team-Special Operations Critical Care Evacuation Team being embedded in civilian facilities to maintain trauma, surgical, and emergency care skills. While military physicians can maintain competencies, at the same time, the civilian sector can benefit from the lessons learned in the military in regard to mass casualty and disaster responses. Fostering military and civilian training agreements can also enhance research opportunities.¹

Just as the realities of operational medicine frequently require the military physician to think outside the box, the most successful methods of instruction of military medicine tend to be nontraditional. Classroom education should be involved beyond lectures and can include other methods, such as case-based, role-playing, small group discussion, and computer-based teaching. Maintaining flexibility in live vs distance learning as well as synchronous vs asynchronous learning can expand the capacity of available instructors and standardize material over several sites.²³ Asking learners to consider operational concerns, such as whether certain medical conditions would be compatible with military duty in addition to the routine investigation is an easy way to incorporate military training in preexisting medical training.¹² The advancement of technology has made simulation one of the best ways to engage in hands-on learning, whether through computer simulations, animal models, standardized or moulaged patients, or mannequins that can realistically mimic medical or trauma-related conditions.²⁴ Many times, simulation can be combined with exercises in the field to create a realistic operational environment.²³

There are 3 pillars of an operational curriculum that should be integrated into the existing residency curriculum—operational medicine, leadership, and research principles (Appendix).

Conclusions

Judging by the continuing operational tempo and evolution of warfare, maintaining enhanced military medical readiness will remain a priority. Operational medicine is a unique field that requires specialized preparation. Studies have shown that longitudinal deliberately mapped out curriculums are able to be integrated well into the existing medical curriculum. The recommendation moving forward is increasing the access of existing operational training structures that have well established programs and modeling individual GME program curriculums after those that have shown proven success with a focus on the 3 pillars of operational training, leadership, and research.

Secondary sources included official reports and studies by the RAND Corporation, the US Government Accountability Office, and the Institute for Defense Analysis (IDA). Due to lack of literature on the topic, other sources such as talking papers, letters, and formal presentations from subject matter experts were included to showcase the current state and gaps on this topic. Key findings from peer-reviewed publications are presented in Table 1.

Overall, the literature review showed that longitudinal deliberately mapped out curriculums can be well integrated into the existing medical curriculum.³ The military medicine course topics include environmental medicine, applied field medicine, combat casualty care, medical support planning, mass casualty incident preparation, and military-focused problem solving, decision making, and leadership.⁴

One 1997 study looked at the degree of implementation of military unique curriculum in 18 family medicine residencies. Only 30% of residents stated that their program had a specific operational medicine curriculum.5 Salerno and colleagues surveyed current residents and recently graduated internal medicine physicians at 14 facilities in the Army, Air Force, and Navy to determine confidence level with military medicine. More than half did not feel ready to practice deployment medicine; just 19% felt comfortable treating nuclear, biologic, and chemical warfare injuries; and 32% felt unfamiliar with the command and administrative duties. A subgroup analysis showed that USU graduates felt more prepared in these areas compared with civilian program graduates.6 Additional studies showed perceived smoother transition in the first active-duty tour after participation in an operational curriculum.⁷

In addition to in-program training, other options include operational rotations offsite and military courses conducted outside the GME program.¹² Some of these courses may include just-in-time training such as expeditionary medical support system training prior to scheduled deployments. Examples of experiential training are listed in Table 3.

Critical Analysis 

Current gaps were identified in the military medicine training pipeline’s operational medicine curriculum and research programs. The analysis looked at specific components that make the operational medicine curriculum and research unique as well as current readiness goals, to determine how to best align both to meet the mission requirements. Some factors considered included efficiency, cost, program portability, duplication minimization, retention, and sustainability.

Efficiency

A well-created curriculum that meets objectives will require more than an assigned rotation and a few lectures. The most successful ones in the literature review were the ones that were deliberately planned and longitudinal, such as the ones at USU that combined a mixture of classroom and field exercises over the course of 4 years.^4,8 In that way, the curriculum may not be considered time efficient, but if integrated well into the already existing medical training, the production of military physicians who are mission ready upon graduation—ready to serve as military medical leaders and deploy—will be invaluable.

Cost Comparison

Due to the associated overhead of running a training platform and the additional hours of operational training, military GME is more expensive initially compared with civilian outsourcing. In USU, for example, there is an additional 700 hours of operational curriculum alone. This cost difference more than doubles the cost of a USU education vs a Health Professional Scholarship Program (HPSP) scholarship at a civilian medical school. However, a causal analysis performed by the IDA to determine value basis noted that USU graduates deploy almost 3 times as much and serve 6 years longer on active duty.³

After graduating medical school through either accession source, physicians complete specialization training in a GME program. The IDA study noted an average $12,000 increased cost of military GME compared with civilian programs. The analysis included resident compensation and overhead costs of running the program as well as the net cost, which also accounted for resident productivity and workload by training in a military facility.³ Calculations due to mandated budget cuts estimated cost savings of closing the military medical school at < $100 million while significantly impacting the military physician pipeline and operational research output.³

Duplication of Effort

There are already established training programs such as Tactical Combat Casualty Care (TCCC) that could be incorporated into the curriculum to avoid expending additional resources to recreate the wheel. USU has a validated operational training curriculum and may be able to make opportunities available for outside trainees to participate in some of its military-unique training and leadership exercises. Other ways to decrease duplication of effort and improve cost efficiency include focusing on the creation of an academic health system (AHS) and consolidating similar programs to conserve resources. Increasing existing military program sizes will not only ensure the continuation of the military medicine pipeline, but will spread overhead costs over a larger cohort, decrease costs of civilian outsourcing, and ensure the less tangible benefits of military cultural exposure early in trainees’ careers. For example, increasing the class size of USU by 30 students actually reduces the cost per student to $239,000 per year from $253,000, while decreasing the need for HPSP accessions training in civilian programs, making the endeavor overall cost neutral.³

Program Portability

The operational medicine residency has proved that an operational curriculum can be remotely managed and reproduced at a variety of residency specialties.¹² Remote education could be developed and distributed throughout the MHS, such as the proposed USU course Military Medicine and Leadership course.3 Centralized training programs like Global Medicine and C-STARS could be scheduled TDYs during the medical training calendar.

Retention

The military medical school, USU, is the largest military medicine accession source. An IDA report notes that retention of USU graduates is 15.2 years compared with 9.2 years served by civilian trainees. Due to the longevity in service, USU graduates also make up more than 25% of military medical leadership.4 The long-term outcome study that looked at the past 40 years of USU graduates observed that over 70% of graduates served until retirement eligibility and are overrepresented in special operations units.3,13 While some of this longevity may be attributed to the longer USU service contracts, military GME graduates were still noted to be 4 times more likely to commit to a multiyear service contract.¹⁴ A RAND study on the retention of military physicians in the Army, Air Force, and Navy noted that overall retention increased throughout all the services for physicians who went through the military GME pipeline.¹⁵ Conversely, civilian GME training was associated with a 45% chance in leaving active duty.¹⁶

It is theorized that early military acculturation during training increases the likelihood of instilling a sense of mission. Being involved in military GME on the teaching side also showed increased retention rates for 63% of survey respondents.¹⁷ Reduced burnout and increased work satisfaction for those involved in military GME was noted on another faculty satisfaction survey.¹⁷

Sustainability

Programs like USU, which have been around for decades, and the newer operational residency program evolving since 2013 have shown sustainability.^4,11 Dissemination of proven curriculums as well as centralization of already validated training programs can help standardize operational medical training throughout the MHS. In order to flourish at individual programs, the faculty need to be well versed in a train the trainer model and have institutional support. The ability to engage with the line at individual locations may be a factor as well.¹⁸ In regard to research, once residents are taught the principles of scholarly activity, they will have the tools to continue operational medicine research advancements and mentoring students.

Discussion

The 2020 NDAA recommends the establishment of an AHS.3 This step will create a culture of military medical readiness from the top down as congressional mandates push reorganization of the MHS, including military GME programs. An overall restructuring of military medicine will require prioritization of resources toward operational requirements vs the historic significant division of attention to beneficiary care that has caused a lack of unity of effort and additional strain on an already heavily tasked medical force. The changes in military GME are just one aspect of that. It is vital to look at the restructuring with a comprehension of the unique challenges of combat health rather than only from an in-garrison, hospital-based aspect.¹⁹ Benefits of having a military medicine AHS include opportunities to share resources and successful business models as well as foster interdisciplinary teamwork and partnerships with civilian health care facilities and research institutions as a force multiplier.¹⁹

There has been recent discussion about budget cuts, including shutting down USU and military GME and transitioning all training to civilian programs to be cost-effective.⁴ If this were to happen, it would be a step backward from the goal of operational readiness. Maintaining US Department of Defense (DoD) control of the military medicine pipeline has innumerable benefits, including built-in mentorship from operationally-seasoned faculty, military leadership development, proficiency in MHS systems, open communication between GME programs and DoD, and curriculum control to ensure focus on readiness.²⁰ Military GME programs are also a significant production source of military-related scholarly activity. Over fiscal year 2017/2018, 63% of the publications out of the San Antonio Uniformed Services Health Education Consortium—the largest Air Force GME platform and second largest multiservice GME platform—involved military relevant medical topics.¹⁷ Much of the volume of operational research as well as the relevant skills learned and future innovations secondary to conducting this research would be lost if military GME did not exist.^17,21

Practically speaking, military GME provides the majority of the military medicine accessions. For example, a presentation by the Air Force Chief of Physician Education noted that the total military GME pipeline included 2875 students, but direct physician access averaged only 20 physicians a year.²² Even if the decision was made to defer to civilian education, capacity does not exist in civilian GME programs. This is worsened by the increased competitiveness of the GME match with the proliferation of medical schools without concurrent increase in residency spots. The 2018 National Resident Matching Program noted that there were more than 37,103 US and foreign applicants for only 33,000 residency positions, leaving many US applicants unmatched.¹⁷ It is doubtful that the civilian GME programs would be able to absorb the influx of military residents, affecting both the military and civilian medicine pipelines. As a secondary effect, the military treatment centers that house the military GME programs would have to close, with surrounding civilian medical facilities also likely unable to absorb the sudden influx of patients and residents losing the intangible benefits of caring for a military population.¹⁵ This was even recognized by the civilian president of the Accreditation Council for Graduate Medical Education:

Military physicians must be trained in the systems of care that are operative in military medicine, which is significantly unlike civilian medicine in many ways. It is often practiced in circumstances that are not seen in civilian medicine, within care structures that are not encountered in American medical practice… Military medicine has advanced research into the care of individuals suffering traumatic injury, critical care, rehabilitation medicine, prosthetics, psychiatric care of those traumatized, and closed head injury, to name a just a few. The sacrifices of our active military demand these advances, and the American Public benefit from these advances.²¹

Where deficiencies exist in military GME, it is possible to use the growing military-civilian training institution partnerships. Two prime examples are the just-in-time deployment training done with civilian trauma facilities by the Air Force Center for the Sustainment of Trauma Readiness Skills and the Air Force Special Operations Surgical Team-Special Operations Critical Care Evacuation Team being embedded in civilian facilities to maintain trauma, surgical, and emergency care skills. While military physicians can maintain competencies, at the same time, the civilian sector can benefit from the lessons learned in the military in regard to mass casualty and disaster responses. Fostering military and civilian training agreements can also enhance research opportunities.¹

Just as the realities of operational medicine frequently require the military physician to think outside the box, the most successful methods of instruction of military medicine tend to be nontraditional. Classroom education should be involved beyond lectures and can include other methods, such as case-based, role-playing, small group discussion, and computer-based teaching. Maintaining flexibility in live vs distance learning as well as synchronous vs asynchronous learning can expand the capacity of available instructors and standardize material over several sites.²³ Asking learners to consider operational concerns, such as whether certain medical conditions would be compatible with military duty in addition to the routine investigation is an easy way to incorporate military training in preexisting medical training.¹² The advancement of technology has made simulation one of the best ways to engage in hands-on learning, whether through computer simulations, animal models, standardized or moulaged patients, or mannequins that can realistically mimic medical or trauma-related conditions.²⁴ Many times, simulation can be combined with exercises in the field to create a realistic operational environment.²³

There are 3 pillars of an operational curriculum that should be integrated into the existing residency curriculum—operational medicine, leadership, and research principles (Appendix).

Conclusions

Judging by the continuing operational tempo and evolution of warfare, maintaining enhanced military medical readiness will remain a priority. Operational medicine is a unique field that requires specialized preparation. Studies have shown that longitudinal deliberately mapped out curriculums are able to be integrated well into the existing medical curriculum. The recommendation moving forward is increasing the access of existing operational training structures that have well established programs and modeling individual GME program curriculums after those that have shown proven success with a focus on the 3 pillars of operational training, leadership, and research.

It is a time of significant change as the Military Health System (MHS) transitions to the purview of the Defense Health Agency (DHA). Additionally, the landscape of combat is ever changing, and military medicine needs to evolve to ensure that the lessons learned are utilized to optimize care of the war fighters. The purpose of this review is to evaluate the available literature on existing operational medicine curriculums and make recommendations to restructure current military medicine training to produce operationally prepared clinicians who are informed in operationally focused research principles.

Operational Medicine

Before diving into the importance of creating a curriculum and investing in training for scholarly activity proficiency, operational medicine needs to be defined. It can be defined as medical care provided in an austere environment with limited resources and possibly under hostile conditions. Another way to look at operational medicine is as the evaluation of normal human physiology and pathology under abnormal conditions. The mission set of each of the services is unique. The Marines and Army may operate forward past the wire vulnerable to the environment, gunfire, and improvised explosive devices, remote from fixed medical facilities. The Navy has divers exposed to the risks of decompression sickness. The Air Force has pilots exposed to altitude changes and strains of G-forces during flight. Locations vary from cold high-altitude mountainous regions to high-temperature desolate deserts. Many times, medical practitioners may be remotely stationed, far from specialty or immediate definitive care. Patient care may consist of low-acuity management of individual patients in sick call to mass casualty events where patient numbers and morbidity may outstrip available resources, making the difficult task of triage necessary.

Despite the challenges of being a uniformed physician, the benefits of being embedded is a better understanding of the roles and capability of the unit. Military physicians need to have the unique knowledge of the type of injuries sustained in that particular theater of war, such as differentiating between the trauma pattern and care required for blast injuries vs high-velocity missiles. There are also chemical, biologic, radiologic, and nuclear threats that military physicians need to recognize. Much of what disables a military fighting force is not a direct relationship to combat-related injuries; however, entire units have been taken down by infectious diarrhea or trench foot. There is also a need for familiarity of the infections and parasitology endemic to the particular theater with the aim of implementation of prevention whenever possible.

Military medicine does not fit in any box. Military physicians need to know the job requirements of various specialties, including elements of occupational medicine, such as aircrew piloting high-performance fighters or ground troops fully loaded with body armor and 80-lb backpacks. There are musculoskeletal injuries from the stressors of various military occupations. Working around weaponry and contact with hostile forces will create scenarios requiring emergent and critical care. In addition to physical injuries, there is the mental strain of combat with the risk of imminent personal injury, the guilt of survivorship, dealing with the scars and permanent physical damage of combat, and prolonged separation from family and other support systems.

The National Defense Authorization Act 2017 mandated the establishment of a standardized process to oversee all military graduate medical education (GME) programs with the goal of ensuring medical operational readiness.¹ This is no small task with > 3000 residents in more than 70 specialties, comprising approximately 12% of US residents.^1,2 Presently, 26 to 32% of the medical corps is enrolled in full-time training compared with 12% of the total force.² With significant time and resources expended during this period, it is vital to maximize the potential of the training.

Literature Review

A literature review was performed, evaluating historical precedence of specialized military medical training and research as well as current operational curriculums. Literature search was conducted in the PubMed and Uniformed Services University (USU) Learning Resource databases using the terms “operational medicine curriculum,” “military medicine curriculum,” “operational medicine training,” “military medicine training,” “operational medicine research,” and “military medicine research,” and included all articles from 1997 to 2020. Inclusion criteria included studies that detailed military medicine training programs and/or outcomes. The source types used in this research project included peer-reviewed journal publications—both review articles and original research—from medical and military journals. The citations of these articles were also reviewed for additional usable publications. Secondary sources included official reports and studies by the RAND Corporation, the US Government Accountability Office, and the Institute for Defense Analysis (IDA). Due to lack of literature on the topic, other sources such as talking papers, letters, and formal presentations from subject matter experts were included to showcase the current state and gaps on this topic. Key findings from peer-reviewed publications are presented in Table 1.

Bayer has voluntarily recalled batches of its Lotrimin and Tinactin products because of benzene detected in some samples, according to an Oct. 1 company announcement, available on the Food and Drug Administration website. “It is important to note that Bayer’s decision to voluntarily recall these products is a precautionary measure and that the levels detected are not expected to cause adverse health consequences in consumers,” the announcement said.

Benzene is classified as a human carcinogen present in the environment from both natural sources and human activity, and it has been shown to cause cancer with long-term exposure.

The products included in the recall – all in aerosol spray cans – are unexpired Lotrimin and Tinactin sprays with lot numbers starting with TN, CV, or NAA that were distributed to consumer venues between September 2018 and September 2021. The over-the-counter products are Lotrimin Anti-Fungal Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal Jock Itch (AFJI) Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal (AF) Athlete’s Foot Deodorant Powder Spray, Lotrimin AF Athlete’s Foot Liquid Spray, Lotrimin AF Athlete’s Foot Daily Prevention Deodorant Powder Spray, Tinactin Jock Itch (JI) Powder Spray, Tinactin Athlete’s Foot Deodorant Powder Spray, Tinactin Athlete’s Foot Powder Spray, and Tinactin Athlete’s Foot Liquid Spray.

Bayer has received no reports of adverse events related to the recall. The company also reported no concerns with its antifungal creams or other products.

In addition, Coppertone has issued a voluntary recall of specific lots of five spray sunscreen products because of the presence of benzene, according to a Sept. 30th company announcement, also posted on the FDA website. The recall includes Pure&Simple spray for babies, children, and adults; Coppertone Sport Mineral Spray; and Travel-sized Coppertone Sport spray. The specific lots were manufactured between January and June 2021, and are listed on the company announcement.

“Daily exposure to benzene at the levels detected in these affected Coppertone aerosol sunscreen spray products would not be expected to cause adverse health consequences based on generally accepted exposure modeling by numerous regulatory agencies,” according to the announcement. Coppertone has received no reports of adverse events related to the recall.

In the announcement, Coppertone advised consumers to discontinue use of the impacted products, dispose of the aerosol cans properly, and contact their physician or health care provider if they experience any problems related to the sunscreen sprays.

In May 2021, online pharmacy Valisure, which routinely tests their medications, petitioned the FDA to recall specific sunscreens after detecting high benzene levels in several brands and batches of sunscreen products. The FDA evaluated the petition, but the agency itself did not issue any recalls of sunscreens.

Clinicians are advised to report any adverse events to the FDA’s MedWatch Adverse Event Reporting program either online or by regular mail or fax using this form.

Bayer has voluntarily recalled batches of its Lotrimin and Tinactin products because of benzene detected in some samples, according to an Oct. 1 company announcement, available on the Food and Drug Administration website. “It is important to note that Bayer’s decision to voluntarily recall these products is a precautionary measure and that the levels detected are not expected to cause adverse health consequences in consumers,” the announcement said.

Benzene is classified as a human carcinogen present in the environment from both natural sources and human activity, and it has been shown to cause cancer with long-term exposure.

The products included in the recall – all in aerosol spray cans – are unexpired Lotrimin and Tinactin sprays with lot numbers starting with TN, CV, or NAA that were distributed to consumer venues between September 2018 and September 2021. The over-the-counter products are Lotrimin Anti-Fungal Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal Jock Itch (AFJI) Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal (AF) Athlete’s Foot Deodorant Powder Spray, Lotrimin AF Athlete’s Foot Liquid Spray, Lotrimin AF Athlete’s Foot Daily Prevention Deodorant Powder Spray, Tinactin Jock Itch (JI) Powder Spray, Tinactin Athlete’s Foot Deodorant Powder Spray, Tinactin Athlete’s Foot Powder Spray, and Tinactin Athlete’s Foot Liquid Spray.

Bayer has received no reports of adverse events related to the recall. The company also reported no concerns with its antifungal creams or other products.

In addition, Coppertone has issued a voluntary recall of specific lots of five spray sunscreen products because of the presence of benzene, according to a Sept. 30th company announcement, also posted on the FDA website. The recall includes Pure&Simple spray for babies, children, and adults; Coppertone Sport Mineral Spray; and Travel-sized Coppertone Sport spray. The specific lots were manufactured between January and June 2021, and are listed on the company announcement.

“Daily exposure to benzene at the levels detected in these affected Coppertone aerosol sunscreen spray products would not be expected to cause adverse health consequences based on generally accepted exposure modeling by numerous regulatory agencies,” according to the announcement. Coppertone has received no reports of adverse events related to the recall.

In the announcement, Coppertone advised consumers to discontinue use of the impacted products, dispose of the aerosol cans properly, and contact their physician or health care provider if they experience any problems related to the sunscreen sprays.

In May 2021, online pharmacy Valisure, which routinely tests their medications, petitioned the FDA to recall specific sunscreens after detecting high benzene levels in several brands and batches of sunscreen products. The FDA evaluated the petition, but the agency itself did not issue any recalls of sunscreens.

Clinicians are advised to report any adverse events to the FDA’s MedWatch Adverse Event Reporting program either online or by regular mail or fax using this form.

Anthem Blue Cross, the country’s second-biggest health insurance company, is behind on billions of dollars in payments owed to hospitals and doctors because of onerous new reimbursement rules, computer problems and mishandled claims, say hospital officials in multiple states.

Anthem, like other big insurers, is using the COVID-19 crisis as cover to institute “egregious” policies that harm patients and pinch hospital finances, said Molly Smith, group vice president at the American Hospital Association. “There’s this sense of ‘Everyone’s distracted. We can get this through.’ ”

Hospitals are also dealing with a spike in retroactive claims denials by UnitedHealthcare, the biggest health insurer, for ED care, the AHA said.

Disputes between insurers and hospitals are nothing new. But this fight sticks more patients in the middle, worried they’ll have to pay unresolved claims. Hospitals say it is hurting their finances as many cope with COVID surges – even after the industry has received tens of billions of dollars in emergency assistance from the federal government.

“We recognize there have been some challenges” to prompt payments caused by claims-processing changes and “a new set of dynamics” amid the pandemic, Anthem spokesperson Colin Manning said in an email. “We apologize for any delays or inconvenience this may have caused.”

Virginia law requires insurers to pay claims within 40 days. In a Sept. 24 letter to state insurance regulators, VCU Health, a system that operates a large teaching hospital in Richmond associated with Virginia Commonwealth University, said Anthem owes it $385 million. More than 40% of the claims are more than 90 days old, VCU said.

For all Virginia hospitals, Anthem’s late, unpaid claims amount to “hundreds of millions of dollars,” the Virginia Hospital and Healthcare Association said in a June 23 letter to state regulators.

Nationwide, the payment delays “are creating an untenable situation,” the American Hospital Association said in a Sept. 9 letter to Anthem CEO Gail Boudreaux. “Patients are facing greater hurdles to accessing care; clinicians are burning out on unnecessary administrative tasks; and the system is straining to finance the personnel and supplies” needed to fight Covid.

Complaints about Anthem extend “from sea to shining sea, from New Hampshire to California,” AHA CEO Rick Pollack told KHN.

Substantial payment delays can be seen on Anthem’s books. On June 30, 2019, before the pandemic, 43% of the insurer’s medical bills for that quarter were unpaid, according to regulatory filings. Two years later that figure had risen to 53% – a difference of $2.5 billion.

Anthem profits were $4.6 billion in 2020 and $3.5 billion in the first half of 2021.

Alexis Thurber, who lives near Seattle, was insured by Anthem when she got an $18,192 hospital bill in May for radiation therapy that doctors said was essential to treat her breast cancer.

The treatments were “experimental” and “not medically necessary,” Anthem said, according to Ms. Thurber. She spent much of the summer trying to get the insurer to pay up – placing two dozen phone calls, spending hours on hold, sending multiple emails and enduring unmeasurable stress and worry. It finally covered the claim months later.

“It’s so egregious. It’s a game they’re playing,” said Ms. Thurber, 51, whose cancer was diagnosed in November. “Trying to get true help was impossible.”

Privacy rules prevent Anthem from commenting on Ms. Thurber’s case, said Anthem spokesperson Colin Manning.

When insurers fail to promptly pay medical bills, patients are left in the lurch. They might first get a notice saying payment is pending or denied. A hospital might bill them for treatment they thought would be covered. Hospitals and doctors often sue patients whose insurance didn’t pay up.

Hospitals point to a variety of Anthem practices contributing to payment delays or denials, including new layers of document requirements, prior-authorization hurdles for routine procedures and requirements that doctors themselves – not support staffers – speak to insurance gatekeepers. “This requires providers to literally leave the patient[’s] bedside to get on the phone with Anthem,” AHA said in its letter.

Anthem often hinders coverage for outpatient surgery, specialty pharmacy and other services in health systems listed as in network, amounting to a “bait and switch” on Anthem members, AHA officials said.

“Demanding that patients be treated outside of the hospital setting, against the advice of the patient’s in-network treating physician, appears to be motivated by a desire to drive up Empire’s profits,” the Greater New York Hospital Association wrote in an April letter to Empire Blue Cross, which is owned by Anthem.

Anthem officials pushed back in a recent letter to the AHA, saying the insurer’s changing rules are intended partly to control excessive prices charged by hospitals for specialty drugs and nonemergency surgery, screening and diagnostic procedures.

Severe problems with Anthem’s new claims management system surfaced months ago and “persist without meaningful improvement,” AHA said in its letter.

Claims have gotten lost in Anthem’s computers, and in some cases VCU Health has had to print medical records and mail them to get paid, VCU said in its letter. The cash slowdown imposes “an unmanageable disruption that threatens to undermine our financial footing,” VCU said.

United denied $31,557 in claims for Emily Long’s care after she was struck in June by a motorcycle in New York City. She needed surgery to repair a fractured cheekbone. United said there was a lack of documentation for “medical necessity” – an “incredibly aggravating” response on top of the distress of the accident, Ms. Long said.

The Brooklyn hospital that treated Ms. Long was “paid appropriately under her plan and within the required time frame,” said United spokesperson Maria Gordon Shydlo. “The facility has the right to appeal the decision.”

United’s unpaid claims came to 54% as of June 30, about the same level as 2 years previously.

When Erin Conlisk initially had trouble gaining approval for a piece of medical equipment for her elderly father this summer, United employees told her the insurer’s entire prior-authorization database had gone down for weeks, said Ms. Conlisk, who lives in California.

“There was a brief issue with our prior-authorization process in mid-July, which was resolved quickly,” Gordon Shydlo said.

When asked by Wall Street analysts about the payment backups, Anthem executives said it partly reflects their decision to increase financial reserves amid the health crisis.

“Really a ton of uncertainty associated with this environment,” John Gallina, the company’s chief financial officer, said on a conference call in July. “We’ve tried to be extremely prudent and conservative in our approach.”

During the pandemic, hospitals have benefited from two extraordinary cash infusions. They and other medical providers have received more than $100 billion through the CARES Act of 2020 and the American Rescue Plan of 2021. Last year United, Anthem and other insurers accelerated billions in hospital reimbursements.

The federal payments enriched many of the biggest, wealthiest systems while poorer hospitals serving low-income patients and rural areas struggled.

Those are the systems most hurt now by insurer payment delays, hospital officials said. Federal relief funds “have been a lifeline, but they don’t make people whole in terms of the losses from increased expenses and lost revenue as a result of the COVID experience,” Mr. Pollack said.

Several health systems declined to comment about claims payment delays or didn’t respond to a reporter’s queries. Among individual hospitals “there is a deep fear of talking on the record about your largest business partner,” AHA’s Ms. Smith said.

Alexis Thurber worried she might have to pay her $18,192 radiation bill herself, and she’s not confident her Anthem policy will do a better job next time of covering the cost of her care.

“It makes me not want to go to the doctor anymore,” she said. “I’m scared to get another mammogram because you can’t rely on it.”

Doctors removed a 4-inch piece of cement from a man’s heart, which had leaked into his body from a spinal surgery, according to a new report published in the New England Journal of Medicine.

The 56-year-old man, who was not identified in the report, went to the emergency room after experiencing 2 days of chest pain and shortness of breath. Imaging scans showed that the chest pain was caused by a foreign object, and he was rushed to surgery.

Surgeons then located and removed a thin, sharp, cylindrical piece of cement and repaired the damage to the patient’s heart. The cement had pierced the upper right chamber of his heart and his right lung, according to the report authors from the Yale University School of Medicine.

A week before, the man had undergone a spinal surgery known as kyphoplasty. The procedure treats spine injuries by injecting a special type of medical cement into damaged vertebrae, according to USA Today. The cement had leaked into the patient’s body, hardened, and traveled to his heart.

The man has now “nearly recovered” since the heart surgery and cement removal, which occurred about a month ago, the journal report stated. He experienced no additional complications.

Cement leakage after kyphoplasty can happen but is an extremely rare complication. Less than 2% of patients who undergo the procedure for osteoporosis or brittle bones have complications, according to patient information from the American Association of Neurological Surgeons.

Music plus mushrooms equals therapy

Magic mushrooms have been used recreationally and medicinally for thousands of years, but researchers have found adding music could be a game changer in antidepressant treatment.

chrissmith12/Pixabay

The ingredient that makes these mushrooms so magical is psilocybin. It works well for the clinical treatment of mental health conditions and some forms of depression because the “trip” can be contained to one work day, making it easy to administer under supervision. With the accompaniment of music, scientists have found that psilocybin evokes emotion.

This recent study, presented at the European College of Neuropsychopharmacology Congress in Lisbon, tested participants’ emotional response to music before and after the psilocybin. Ketanserin, an antihypertensive drug, was used to test against the effects of psilocybin. The scientist played Mozart and Elgar and found that participants on psilocybin had an emotional response increase of 60%. That response was even greater, compared with ketanserin, which actually lessened the emotional response to music.

“This shows that combination of psilocybin and music has a strong emotional effect, and we believe that this will be important for the therapeutic application of psychedelics if they are approved for clinical use,” said lead researcher Dea Siggaard Stenbæk of the University of Copenhagen.

Professor David J. Nutt of Imperial College in London, who was not involved in the study, said that it supports the use of music for treatment efficacy with psychedelics and suggested that the next step is to “optimise this approach probably through individualising and personalising music tracks in therapy.”

Cue the 1960s LSD music montage.
 

Chicken ‘white striping is not a disease’

Have you ever sliced open a new pack of chicken breasts to start dinner and noticed white fatty lines running through the chicken? Maybe you thought it was just some extra fat to trim off, but the Humane League calls it “white striping disease.”

Chicken is the No. 1 meat consumed by Americans, so it’s not surprising that chickens are factory farmed and raised to be ready for slaughter quickly, according to CBSNews.com, which reported that the Humane League claims white striping is found in 70% of the chicken in popular grocery stores. The league expressed concern for the chickens’ welfare as they are bred to grow bigger quickly, which is causing the white striping and increasing the fat content of the meat by as much as 224%.

The National Chicken Council told CBS that the league’s findings were unscientific. A spokesperson said, “White striping is not a disease. It is a quality factor in chicken breast meat caused by deposits of fat in the muscle during the bird’s growth and development.” He went on to say that severe white striping happens in 3%-6% of birds, which are mostly used in further processed products, not in chicken breast packages.

Somehow, that’s not making us feel any better.
 

The itsy bitsy spider lets us all down

Most people do not like spiders. That’s too bad, because spiders are generally nothing but helpful little creatures that prey upon annoying flies and other pests. Then there’s the silk they produce. The ancient Romans used it to treat conditions such as warts and skin lesions. Spiders wrap their eggs in silk to protect them from harmful bacteria.

Simon Fruergaard

Of course, we can hardly trust the medical opinions of people from 2,000 years ago, but modern-day studies have not definitively proved whether or not spider silk has any antimicrobial properties.

To settle the matter once and for all, researchers from Denmark built a silk-harvesting machine using the most famous of Danish inventions: Legos. The contraption, sort of a paddle wheel, pulled the silk from several different species of spider pinned down by the researchers. The silk was then tested against three different bacteria species, including good old Escherichia coli.

Unfortunately for our spider friends, their silk has no antimicrobial activity. The researchers suspected that any such activity seen in previous studies was actually caused by improper control for the solvents used to extract the silk; those solvents can have antimicrobial properties on their own. As for protecting their eggs, rather than killing bacteria, the silk likely provides a physical barrier alone.

It is bad news for spiders on the benefit-to-humanity front, but look at the bright side: If their silk had antimicrobial activity, we’d have to start farming them to acquire more silk. And that’s no good. Spiders deserve to roam free, hunt as they please, and drop down on your head from the ceiling.
 

Anxiety and allergies: Cause, effect, confusion

We’re big fans of science, but as longtime, totally impartial (Science rules!) observers of science’s medical realm, we can see that the day-to-day process of practicing the scientific method occasionally gets a bit messy. And no, we’re not talking about COVID-19.

We’re talking allergies. We’re talking mental health. We’re talking allergic disease and mental health.

We’re talking about a pair of press releases we came across during our never-ending search for material to educate, entertain, and astound our fabulously wonderful and loyal readers. (We say that, of course, in the most impartial way possible.)

The first release was titled, “Allergies including asthma and hay fever not linked to mental health traits” and covered research from the University of Bristol (England). The investigators were trying to determine if “allergic diseases actually causes mental health traits including anxiety, depression, bipolar disorder, and schizophrenia, or vice versa,” according to the release.

What they found, however, was “little evidence of a causal relationship between the onset of allergic disease and mental health.” Again, this is the press release talking.

The second release seemed to suggest the exact opposite: “Study uncovers link between allergies and mental health conditions.” That got our attention. A little more reading revealed that “people with asthma, atopic dermatitis, and hay fever also had a higher likelihood of having depression, anxiety, bipolar disorder, or neuroticism.”

One of the investigators was quoted as saying, “Establishing whether allergic disease causes mental health problems, or vice versa, is important to ensure that resources and treatment strategies are targeted appropriately.”

Did you notice the “vice versa”? Did you notice that it appeared in quotes from both releases? We did, so we took a closer look at the source. The second release covered a group of investigators from the University of Bristol – the same group, and the same study, in fact, as the first one.

So there you have it. One study, two press releases, and one confused journalist. Thank you, science.

Music plus mushrooms equals therapy

Magic mushrooms have been used recreationally and medicinally for thousands of years, but researchers have found adding music could be a game changer in antidepressant treatment.

The ingredient that makes these mushrooms so magical is psilocybin. It works well for the clinical treatment of mental health conditions and some forms of depression because the “trip” can be contained to one work day, making it easy to administer under supervision. With the accompaniment of music, scientists have found that psilocybin evokes emotion.

This recent study, presented at the European College of Neuropsychopharmacology Congress in Lisbon, tested participants’ emotional response to music before and after the psilocybin. Ketanserin, an antihypertensive drug, was used to test against the effects of psilocybin. The scientist played Mozart and Elgar and found that participants on psilocybin had an emotional response increase of 60%. That response was even greater, compared with ketanserin, which actually lessened the emotional response to music.

“This shows that combination of psilocybin and music has a strong emotional effect, and we believe that this will be important for the therapeutic application of psychedelics if they are approved for clinical use,” said lead researcher Dea Siggaard Stenbæk of the University of Copenhagen.

Professor David J. Nutt of Imperial College in London, who was not involved in the study, said that it supports the use of music for treatment efficacy with psychedelics and suggested that the next step is to “optimise this approach probably through individualising and personalising music tracks in therapy.”

Cue the 1960s LSD music montage.
 

Chicken ‘white striping is not a disease’

Have you ever sliced open a new pack of chicken breasts to start dinner and noticed white fatty lines running through the chicken? Maybe you thought it was just some extra fat to trim off, but the Humane League calls it “white striping disease.”

Chicken is the No. 1 meat consumed by Americans, so it’s not surprising that chickens are factory farmed and raised to be ready for slaughter quickly, according to CBSNews.com, which reported that the Humane League claims white striping is found in 70% of the chicken in popular grocery stores. The league expressed concern for the chickens’ welfare as they are bred to grow bigger quickly, which is causing the white striping and increasing the fat content of the meat by as much as 224%.

The National Chicken Council told CBS that the league’s findings were unscientific. A spokesperson said, “White striping is not a disease. It is a quality factor in chicken breast meat caused by deposits of fat in the muscle during the bird’s growth and development.” He went on to say that severe white striping happens in 3%-6% of birds, which are mostly used in further processed products, not in chicken breast packages.

Somehow, that’s not making us feel any better.
 

The itsy bitsy spider lets us all down

Most people do not like spiders. That’s too bad, because spiders are generally nothing but helpful little creatures that prey upon annoying flies and other pests. Then there’s the silk they produce. The ancient Romans used it to treat conditions such as warts and skin lesions. Spiders wrap their eggs in silk to protect them from harmful bacteria.

Simon Fruergaard

Of course, we can hardly trust the medical opinions of people from 2,000 years ago, but modern-day studies have not definitively proved whether or not spider silk has any antimicrobial properties.

To settle the matter once and for all, researchers from Denmark built a silk-harvesting machine using the most famous of Danish inventions: Legos. The contraption, sort of a paddle wheel, pulled the silk from several different species of spider pinned down by the researchers. The silk was then tested against three different bacteria species, including good old Escherichia coli.

Unfortunately for our spider friends, their silk has no antimicrobial activity. The researchers suspected that any such activity seen in previous studies was actually caused by improper control for the solvents used to extract the silk; those solvents can have antimicrobial properties on their own. As for protecting their eggs, rather than killing bacteria, the silk likely provides a physical barrier alone.

It is bad news for spiders on the benefit-to-humanity front, but look at the bright side: If their silk had antimicrobial activity, we’d have to start farming them to acquire more silk. And that’s no good. Spiders deserve to roam free, hunt as they please, and drop down on your head from the ceiling.

A handheld vision screening device to test for amblyopia and strabismus has been found to have a sensitivity of 100%, a specificity of 85%, and a median acquisition time of 28 seconds, according to a study published in the Journal of American Association for Pediatric Ophthalmology and Strabismus.

The prospective study involved 300 children recruited from two Kaiser Permanente Southern California pediatric clinics. The patients, aged 24-72 months, were first screened by trained research staff for amblyopia and strabismus using the device, called the Pediatric Vision Scanner (PVS). They were subsequently screened by a pediatric ophthalmologist who was masked to the previous screening results and who then performed a comprehensive eye examination.

With the gold-standard ophthalmologist examination, six children (2%) were identified as having amblyopia and/or strabismus. Using the PVS, all six children with amblyopia and/or strabismus were identified, yielding 100% sensitivity. PVS findings were normal for 45 children (15%), yielding a specificity rate of 85%. The positive predictive value was 26.0% (95% confidence interval, 12.4%-32.4%), and the negative predictive value was 100% (95% CI, 97.1%-100%).

The findings suggest that the device could be used to screen for amblyopia, according to Shaival S. Shah, MD, the study’s first author, who is a pediatric ophthalmologist and regional section lead of pediatric ophthalmology, Southern California Permanente Medical Group.

“A strength of this device is that it is user friendly and easy to use and very quick, which is essential when working with young children,” said Dr. Shah in an interview. He noted that the device could be used for children as young as 2 years.

Dr. Shah pointed out that the children were recruited from a pediatrician’s office and reflect more of a “real-world setting” than had they been recruited from a pediatric ophthalmology clinic.

Dr. Shah added that, with a negative predictive value of 100%, the device is highly reliable at informing the clinician that amblyopia is not present. “It did have a positive predictive value of 26%, which needs to be considered when deciding one’s vision screening strategy,” he said.

A limitation of the study is that there was no head-to-head comparison with another screening device, noted Dr. Shah. “While it may have been more useful to include another vision screening device to have a head-to-head comparison, we did not do this to limit complexity and cost.”

Michael J. Wan, MD, FRCSC, pediatric ophthalmologist, Sick Kids Hospital, Toronto, and assistant professor at the University of Toronto, told this news organization that the device has multiple strengths, including quick acquisition time and excellent detection rate of amblyopia and strabismus in children as young as 2 years.

“It is highly reliable at informing the clinician that amblyopia is not present,” said Dr. Wan, who was not involved in the study. “The PVS uses an elegant mechanism to test for amblyopia directly (as opposed to other screening devices, which only detect risk factors). This study demonstrates the impressive diagnostic accuracy of this approach. With a study population of 300 children, the PVS had a sensitivity of 100% and specificity of 85% (over 90% in cooperative children). This means that the PVS would detect essentially all cases of amblyopia and strabismus while minimizing the number of unnecessary referrals and examinations.”

He added that, although the study included children as young as 2 years, only 2.5% of the children were unable to complete the PVS test. “Detecting amblyopia in children at an age when treatment is still effective has been a longstanding goal in pediatric ophthalmology,” said Dr. Wan, who described the technology as user friendly. “Based on this study, the search for an accurate and practical pediatric vision screening device appears to be over.”

Dr. Wan said it would be useful to replicate this study with a different population to confirm the findings.

Dr. Shah and Dr. Wan disclosed no relevant financial relationships.

Third-year medical student Liz Groesbeck was like other excited Las Vegas Raiders fans recently headed to the first full-capacity game in the new Allegiant Stadium since the team moved to “Sin City.” She was in an Uber on a first date just blocks from the game that would pit her Raiders against the Seattle Seahawks when she saw a man on the ground and people gathered around him.

Abandoning her keys, cellphone, and date in the Uber, Ms. Groesbeck popped out to see if she could help. The Uber had been stuck in traffic, so Ms. Groesbeck thought she’d still be able to jump back in the car if she wasn’t needed. 

Then she heard screams. “That didn’t concern me. People scream whenever anything unexpected happens,” said the 28-year-old student from the Kirk Kerkorian School of Medicine at the University of Nevada, Las Vegas (UNLV). But the screams were only a small indication of what she would discover on closer inspection. The arm of the middle-aged man lying on the ground was detached. An abandoned gold SUV remained on the curb nearby. It would turn out to be a hit-and-run of pedestrians by a driver later charged by police with DUI. 

“I was one of the first people there,” Ms. Groesbeck recounted for this news organization. “I knew this guy did not just fall. I told someone to call EMS and I got someone to take his wife somewhere else [away from the bloody scene]. She was obviously very distraught. …At a couple of points she was hysterical.” 

Next, Ms. Groesbeck, who, ironically, had finished her emergency general surgery rotation the day before, focused on the patient. Kneeling beside him, she determined that the immediate priorities were to stop the bleeding and clear his airway. “He was barely breathing,” she recounted. Another student who Ms. Groesbeck believes was pursuing a medical degree — there wasn’t time for formal introductions — offered to help, along with bystanders headed to the game. 

“The crowd was very energetic. It was a beautiful thing.” Ms. Groesbeck cited the spirit of saving lives that developed from the October 1, 2017, Las Vegas country music festival shooting. “People are very willing to try to help others in any way they can.” 

MS. Groesbeck, leading the effort, asked for belts, “and bystanders immediately provided that,” and the other student followed Ms. Groesbeck’s directions to apply tourniquets with the help of those around her. With the blood loss being stemmed, Ms. Groesbeck’s next priority was making sure the patient could breathe. 

Appealing for clothing to clear the man’s airway, “five shirts were handed in a circle to me.” She only needed one jersey to scoop the blood out of his mouth manually to free his airway. 

She overruled well-meaning suggestions to lay the man on his side — which she was concerned could paralyze him — or use a straw to help him breathe. “I did not want to stick anything down his throat.” Meanwhile, there was so much traffic that night around Allegiant Stadium that when the ambulance couldn’t get any closer the firefighters and paramedics exited the vehicle and ran to the scene. 
 

From training to practice

The decisions Ms. Groesbeck made until they could arrive called upon her years of training to be a doctor, and specifically an EMT certification course she had to pass before beginning medical school, she said.

She credits the life-saving methods she learned in that course to Douglas Fraser, MD, FACS, associate professor of surgery at UNLV and University Medical Center (UMC) trauma medical director. He happened to be the attending physician when the accident victim was admitted to the hospital that night in critical condition. The man’s wife also was injured, but not to the extent of her husband.

Dr. Fraser said he didn’t know at the time that his student had been involved in saving the man’s life until Ms. Groesbeck reached out to say thanks for teaching her what to do in an emergency. “I [first] was overly impressed that she did that. Students are so busy; they move after they graduate or finish their rotations. You don’t get to see them time and time again; your short time with them could have a lasting impact and that is my goal,” Dr. Fraser told this news organization.

“They rarely thank you or reflect back. It renewed my sense that I want to teach more, to see the positive impact it had on Elizabeth” and other students, he said.

In terms of the emergency situation she navigated, Dr. Fraser said he was very proud of his student, but was also concerned she could have gotten hurt herself in the middle of a busy intersection. “She was selfless and put herself in harm’s way to help someone.” He also noted it was the first time he knew of a student putting her skills to the test so soon after learning them. “It was a good outcome and she truly provided lifesaving care to this victim.”

He attributed her training to the Stop the Bleed program, which began after the Sandy Hook tragedy in 2012. UNLV requires new med students to complete the American College of Surgeons’ first aid program to learn how to stop the bleeding of a severely injured person by applying tourniquets and pressure. “You have to stop the bleeding right away…and look to see whether their airway is open and if it’s not, open their airway or you won’t have a patient very long. I know she did that. These are the two most important lifesaving skills that she did.” 

Medical students are often called upon as doctors by their family and friends, Dr. Fraser continued. “Everyone looks to you. It can happen on an airplane; you can be anywhere. She heard a person was in need and jumped to action and was able to use the training her school provided and was able to put it to good use.” 
 

Not her first call to action

Just the week before the incident, Ms. Groesbeck was on clinical rotations at UMC helping in the emergency and operating rooms. “She was always very engaged and mature beyond her years,” Dr. Fraser said. “She definitely had that ‘it’ factor. She was sincere with patients and their families and performed well in the operating room. …She was very comfortable around the patients; very comfortable in stressful situations.” 

He added, “I look forward to her participating in trauma surgery rotations in the near future.”

In the meantime, Ms. Groesbeck was pleased to learn that the man she saved survived and thrilled to be part of that effort. As of press time, he had not contacted her. Nor has the other student who helped save his life. 

“A lot of people stepped up and donated their time to help. He got lucky on a very unlucky day,” Ms. Groesbeck said.

She recalled a previous accident victim years ago who wasn’t as lucky. On the way to pick up her white coat for the ceremony before her first year of medical school, she came upon a car that had flipped upside down. “It sheared the roof away. I checked on the restrained passenger. He was partially scalped. The windows were broken and I climbed in next to him.” This time, she used her own shirt to hold pressure on the wound. “He, unfortunately did not make it.” There was nothing she could have done, she was told. 

“That one got me mentally. Very graphic imaging was stuck in my head,” Ms. Groesbeck said. With a masters in neuroscience, she was accustomed to seeing the brain, “but not like this. I felt sad he passed in such a violent way.” So the more recent life-saving experience was redemptive, she said. “I’ve been through hell and back.”

And she’s still on track to become the doctor she envisioned as a child, mummifying her cats with gauze wraps and covering her little sister with adhesive bandages. “It felt good knowing what I could do,” Ms. Groesbeck said. “I’m glad this [man] made it. He got lucky and he could go home to his family. I was not positive when he left in the ambulance. It was a huge relief.” 

Of her role in the episode and her future career ambitions, Ms. Groesbeck noted: “We are studying all the time. It’s not very rewarding. But this, not thinking but having sprung into action, doing the right thing and he could go home to his family a week later. It’s things like this that make the endless hours of studying worth it. I feel like I accomplished something.”

Third-year medical student Liz Groesbeck was like other excited Las Vegas Raiders fans recently headed to the first full-capacity game in the new Allegiant Stadium since the team moved to “Sin City.” She was in an Uber on a first date just blocks from the game that would pit her Raiders against the Seattle Seahawks when she saw a man on the ground and people gathered around him.

Abandoning her keys, cellphone, and date in the Uber, Ms. Groesbeck popped out to see if she could help. The Uber had been stuck in traffic, so Ms. Groesbeck thought she’d still be able to jump back in the car if she wasn’t needed. 

Then she heard screams. “That didn’t concern me. People scream whenever anything unexpected happens,” said the 28-year-old student from the Kirk Kerkorian School of Medicine at the University of Nevada, Las Vegas (UNLV). But the screams were only a small indication of what she would discover on closer inspection. The arm of the middle-aged man lying on the ground was detached. An abandoned gold SUV remained on the curb nearby. It would turn out to be a hit-and-run of pedestrians by a driver later charged by police with DUI. 

“I was one of the first people there,” Ms. Groesbeck recounted for this news organization. “I knew this guy did not just fall. I told someone to call EMS and I got someone to take his wife somewhere else [away from the bloody scene]. She was obviously very distraught. …At a couple of points she was hysterical.” 

Next, Ms. Groesbeck, who, ironically, had finished her emergency general surgery rotation the day before, focused on the patient. Kneeling beside him, she determined that the immediate priorities were to stop the bleeding and clear his airway. “He was barely breathing,” she recounted. Another student who Ms. Groesbeck believes was pursuing a medical degree — there wasn’t time for formal introductions — offered to help, along with bystanders headed to the game. 

“The crowd was very energetic. It was a beautiful thing.” Ms. Groesbeck cited the spirit of saving lives that developed from the October 1, 2017, Las Vegas country music festival shooting. “People are very willing to try to help others in any way they can.” 

MS. Groesbeck, leading the effort, asked for belts, “and bystanders immediately provided that,” and the other student followed Ms. Groesbeck’s directions to apply tourniquets with the help of those around her. With the blood loss being stemmed, Ms. Groesbeck’s next priority was making sure the patient could breathe. 

Appealing for clothing to clear the man’s airway, “five shirts were handed in a circle to me.” She only needed one jersey to scoop the blood out of his mouth manually to free his airway. 

She overruled well-meaning suggestions to lay the man on his side — which she was concerned could paralyze him — or use a straw to help him breathe. “I did not want to stick anything down his throat.” Meanwhile, there was so much traffic that night around Allegiant Stadium that when the ambulance couldn’t get any closer the firefighters and paramedics exited the vehicle and ran to the scene. 
 

From training to practice

The decisions Ms. Groesbeck made until they could arrive called upon her years of training to be a doctor, and specifically an EMT certification course she had to pass before beginning medical school, she said.

She credits the life-saving methods she learned in that course to Douglas Fraser, MD, FACS, associate professor of surgery at UNLV and University Medical Center (UMC) trauma medical director. He happened to be the attending physician when the accident victim was admitted to the hospital that night in critical condition. The man’s wife also was injured, but not to the extent of her husband.

Dr. Fraser said he didn’t know at the time that his student had been involved in saving the man’s life until Ms. Groesbeck reached out to say thanks for teaching her what to do in an emergency. “I [first] was overly impressed that she did that. Students are so busy; they move after they graduate or finish their rotations. You don’t get to see them time and time again; your short time with them could have a lasting impact and that is my goal,” Dr. Fraser told this news organization.

“They rarely thank you or reflect back. It renewed my sense that I want to teach more, to see the positive impact it had on Elizabeth” and other students, he said.

In terms of the emergency situation she navigated, Dr. Fraser said he was very proud of his student, but was also concerned she could have gotten hurt herself in the middle of a busy intersection. “She was selfless and put herself in harm’s way to help someone.” He also noted it was the first time he knew of a student putting her skills to the test so soon after learning them. “It was a good outcome and she truly provided lifesaving care to this victim.”

He attributed her training to the Stop the Bleed program, which began after the Sandy Hook tragedy in 2012. UNLV requires new med students to complete the American College of Surgeons’ first aid program to learn how to stop the bleeding of a severely injured person by applying tourniquets and pressure. “You have to stop the bleeding right away…and look to see whether their airway is open and if it’s not, open their airway or you won’t have a patient very long. I know she did that. These are the two most important lifesaving skills that she did.” 

Medical students are often called upon as doctors by their family and friends, Dr. Fraser continued. “Everyone looks to you. It can happen on an airplane; you can be anywhere. She heard a person was in need and jumped to action and was able to use the training her school provided and was able to put it to good use.” 
 

Not her first call to action

Just the week before the incident, Ms. Groesbeck was on clinical rotations at UMC helping in the emergency and operating rooms. “She was always very engaged and mature beyond her years,” Dr. Fraser said. “She definitely had that ‘it’ factor. She was sincere with patients and their families and performed well in the operating room. …She was very comfortable around the patients; very comfortable in stressful situations.” 

He added, “I look forward to her participating in trauma surgery rotations in the near future.”

In the meantime, Ms. Groesbeck was pleased to learn that the man she saved survived and thrilled to be part of that effort. As of press time, he had not contacted her. Nor has the other student who helped save his life. 

“A lot of people stepped up and donated their time to help. He got lucky on a very unlucky day,” Ms. Groesbeck said.

She recalled a previous accident victim years ago who wasn’t as lucky. On the way to pick up her white coat for the ceremony before her first year of medical school, she came upon a car that had flipped upside down. “It sheared the roof away. I checked on the restrained passenger. He was partially scalped. The windows were broken and I climbed in next to him.” This time, she used her own shirt to hold pressure on the wound. “He, unfortunately did not make it.” There was nothing she could have done, she was told. 

“That one got me mentally. Very graphic imaging was stuck in my head,” Ms. Groesbeck said. With a masters in neuroscience, she was accustomed to seeing the brain, “but not like this. I felt sad he passed in such a violent way.” So the more recent life-saving experience was redemptive, she said. “I’ve been through hell and back.”
