Gender-diverse teens face barriers to physical activity
WASHINGTON – in a poster presented at the Pediatric Academic Societies annual meeting. Other barriers included body dissatisfaction and discomfort or pain from binding or tucking, based on data from 160 individuals.
Previous studies suggest that gender-diverse teens have lower levels of physical activity than cisgender teens, but data on the specific barriers to physical activity reported by gender-diverse adolescents are lacking, according to Karishma Desai, BA, a medical student at Northwestern University, Chicago, and colleagues.
The researchers reviewed data from adolescents aged 13-18 years who identified as transgender or nonbinary and lived in the United States. Participants were recruited through flyers, wallet cards, email, and social media. They completed an online survey that included questions on preferred types of physical activity and potential barriers to physical activity. Major barriers were defined as items that “almost always” or “always” got in the way of physical activity.
Overall, 51% of the participants identified as female/transfeminine, 31% as male/transmasculine, 9% as genderqueer or agender, 8% as nonbinary, and 1% as unsure. A total of 86 participants were assigned male at birth, 73 were assigned female, and 1 was assigned intersex or other. Nearly all of the participants (96%) had begun social transition; approximately half (48%) reported using a chest binder, and 75% had been or were currently taking gender-affirming hormones.
Potential negative judgment from others was the top barrier to physical activity (cited by 39% of participants), followed by body dissatisfaction from gender dysphoria (38%) and discomfort with the available options for locker rooms or changing rooms (38%). Approximately one-third (36%) of respondents reported physical discomfort or pain from binding or tucking as a barrier to physical activity, and 34% cited discomfort with requirements for a physical activity uniform or athletic clothing at school. Other gender-diverse specific barriers to physical activity included bullying related to being transgender (31%) and the inability to participate in a group of choice because of gender identity (24%).
In addition, participants cited general barriers to physical activity including bullying related to weight (33%), dissatisfaction with weight or size (31%), and bullying in general or for reasons other than gender status (29%).
However, more than 50% of respondents said they were comfortable or very comfortable (4 or 5 on a 5-point Likert Scale) with physical activity in the settings of coed or all-gender teams (61%) or engaging in individual activities (71%). By contrast, 36% were comfortable or very comfortable with a team, group, or class that aligned with sex assignment at birth.
The majority of participants (81%) were comfortable or very comfortable with their homes or a private location as a setting for physical activity, 54% with a public space such as a park, and 43% with a school setting.
Increasing gender congruence was the biggest facilitator of physical activity, reported by 53% of participants, the researchers noted. Other facilitators of physical activity included increasing body satisfaction (43%), staying healthy to avoid long-term health problems in the future (43%), and staying healthy to prepare for gender-related surgery in the future (18%).
The study findings were limited by the use of self-reports and the use of a convenience sample, as well as the lack of data on race, the researchers noted. However, the results suggest that access to all-gender teams, standardizing physical activity clothing, and increasing inclusive facilities may promote greater physical activity participation by gender-diverse adolescents, and offering private or individual options may increase comfort with physical activity, they concluded.
Study provides teens’ perspectives
The current study is especially timely given the recent passage by the U.S. House of Representatives of the anti-trans sports bill preventing transgender women and girls from playing on sports teams “consistent with their gender identity,” said Margaret Thew, DNP, medical director of adolescent medicine at Children’s Wisconsin in Milwaukee, in an interview. Ms. Thew was not involved in the current study.
“The House bill seeks to amend federal law to require that sex shall be recognized based solely on a person’s reproductive biology and genetics at birth, for the purpose of determining compliance with Title IX in athletics,” Ms. Thew said.
“Despite political responses to sports participation for transgender adolescents, we have not heard the perspective of the teens themselves,” she emphasized. “It is imperative for parents, coaches, and clinicians to hear the adolescents’ concerns so they can advocate for the students and provide the needed support.” In addition, Ms. Thew noted, “these concerns may also provide overdue changes to the required uniforms described for specific sports.”
Ms. Thew said she was surprised by the finding of transgender teens’ comfort with coed teams and individual activities, both of which may be opportunities to promote physical activity for transgender adolescents.
However, she added that she was not surprised by some of the results. “Many transgender adolescents experience the discomfort and further body dysmorphia of being put into gender-conforming attire such as swimwear, spandex shorts for female volleyball players, or field hockey skirts, for example.”
Although many schools are establishing safe, comfortable places for all adolescents to change clothing prior to physical education and sports participation, “resources are limited, and students and parents need to advocate within the school system,” Ms. Thew noted.
“We as a society, including athletic clothing makers, need to hear the testimony of transgender adolescents on the discomfort from body modifications to better support and innovate attire to meet their needs,” she added.
“The take-home message for clinicians is twofold,” said Ms. Thew. “Clinicians need to advocate for transgender patients to have the same opportunities as all teens when it comes to sports participation and physical activity. Also, clinicians need to ask all adolescents about their comfort in participating in physical activity both on club/school teams and independently,” she said. “If barriers are identified, clinicians need to work to support the adolescent with alternative activities/attire that will promote healthy physical activities for overall health.”
The current study also suggests that transgender adolescents who may have interest in, but discomfort with, physical activity should be redirected to coed or individual sports available in their communities, Ms. Thew added.
More research is needed on innovative sports attire that would improve comfort for transgender adolescents and thereby encourage physical activity, Ms. Thew told this news organization. More data also are needed on which sports transgender adolescents participate in and why, and how these activities might be promoted, she said.
Finally, more research will be needed to examine the impact of the recent House bills on physical activity for transgender youth, Ms. Thew said.
The study was supported by the Potocsnak Family Division of Adolescent and Young Adult Medicine at Ann and Robert H. Lurie’s Children’s Hospital of Chicago. The researchers had no financial conflicts to disclose. Ms. Thew had no financial conflicts to disclose, but she serves on the Editorial Advisory Board of Pediatric News.

Why is buprenorphine use flatlining?
Opioid overdose deaths are at a record high in the United States, and many of these deaths can be prevented with medications such as buprenorphine, said lead author Kao-Ping Chua, MD, of the University of Michigan, Ann Arbor, in an interview. “However, buprenorphine cannot prevent opioid overdose deaths if patients are never started on the medication or only stay on the medication for a short time. For that reason, rates of buprenorphine initiation and retention are critical metrics for measuring how well the U.S. health care system is responding to the opioid epidemic,” he said.
“At the time we started our study, several other research groups had evaluated U.S. rates of buprenorphine initiation and retention using data through 2020. However, more recent national data were lacking,” Dr. Chua told this news organization. “We felt that this was an important knowledge gap given the many changes in society that have occurred since 2020,” he noted. “For example, it was possible that the relaxation of social distancing measures during 2021 and 2022 might have reduced barriers to health care visits, thereby increasing opportunities to initiate treatment for opioid addiction with buprenorphine,” he said.
Dr. Chua and colleagues used data from the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed from retail pharmacies in the United States. “Buprenorphine products included immediate-release and extended-release formulations approved for opioid use disorder but not formulations primarily used to treat pain,” they write.
Monthly buprenorphine initiation was defined as the number of patients initiating therapy per 100,000 individuals. For retention, the researchers used a National Quality Forum-endorsed quality measure that defined retention as continuous use of buprenorphine for at least 180 days.
A total of 3,006,629 patients began buprenorphine therapy during the study period; approximately 43% were female.
During the first years of the study period, from January 2016 through September 2018, the monthly buprenorphine initiation rate increased from 12.5 per 100,000 to 15.9 per 100,000, with a statistically significant monthly percentage change of 0.62% (P < .001).
However, from October 2018 through October 2022, the monthly percentage remained essentially the same (P = .62) with a monthly percentage change of −0.03%.
From March 2020 through December 2020, the median monthly buprenorphine initiation rate was 14.4 per 100,000, only slightly lower than the rates from January 2019 through February 2020 and from January 2021 through October 2022 (15.5 per 100,000 and 15.0 per 100,000, respectively).
Over the entire study period from January 2016 through October 2022, the median monthly retention rate for buprenorphine use was 22.2%. This rate increased minimally, with no significant changes in slope and a monthly percentage change of 0.08% (P = .04).
The study findings were limited by several factors, including a lack of data on race and ethnicity, in-clinic administration of buprenorphine, and buprenorphine dispensing through methadone outpatient programs, the researchers note. Also, data did not indicate whether some patients began buprenorphine to treat pain, they say. The timing of the flattening of buprenorphine use also suggests the influence of factors beyond the COVID-19 pandemic, they write.
However, the results were strengthened by the large sample size and suggest that efforts to date to increase buprenorphine use have been unsuccessful, the researchers write. “A comprehensive approach is needed to eliminate barriers to buprenorphine initiation and retention, such as stigma and uneven access to prescribers,” they conclude.
Study highlights underuse of buprenorphine option
“Our study shows that buprenorphine initiation rates have been flat since the end of 2018 and that rates of 180-day retention in buprenorphine therapy have remained low throughout 2016-2022,” Dr. Chua told this news organization. “Neither of these findings are particularly surprising, but they are disappointing,” he said. “There were a lot of policy and clinical efforts to maintain and expand access to buprenorphine during the COVID-19 pandemic, such as allowing buprenorphine to be prescribed via telehealth without an in-person visit and eliminating training requirements for the waiver that previously was required to prescribe buprenorphine.
“The fact that buprenorphine initiation and retention did not rise after these efforts were implemented suggests that they were insufficient to meet the rising need for this medication,” he said.
The current study “adds to a growing body of research suggesting that clinicians are not maximizing opportunities to initiate buprenorphine treatment among patients with opioid addiction,” Dr. Chua said. He cited another of his recent studies in which 1 in 12 patients were prescribed buprenorphine within 30 days of an emergency department visit for opioid overdose from August 2019 to April 2021, but half of patients with emergency department visits with anaphylaxis were prescribed anepinephrine auto-injector.
“My hope is that our new study will further underscore to clinicians how much the health care system is underusing a critical tool to prevent opioid overdose deaths,” he said.
The federal government’s recent elimination of the waiver needed to prescribe buprenorphine may move the needle, but to what degree remains to be seen, Dr. Chua added. “It is possible this intervention will be insufficient to overcome the many other barriers to buprenorphine initiation and retention, such as stigma about the drug among clinicians, patients, and pharmacists,” he said.
Lack of education remains a barrier to buprenorphine use
The current study is important to determine whether attempts to increase buprenorphine initiation and treatment retention are working, said Reuben J. Strayer, MD, director of addiction medicine in the emergency medicine department at Maimonides Medical Center, New York, in an interview.
Dr. Strayer was not involved in the current study, but said he was surprised that initiation of buprenorphine didn’t decrease more dramatically during the pandemic, given the significant barriers to accessing care during that time.
However, “efforts to increase buprenorphine initiation and retention have not been sufficiently effective,” Dr. Strayer said. “The rise of fentanyl as a primary street opioid, replacing heroin, has dissuaded both patients and providers from initiating buprenorphine for fear of precipitated withdrawal.”
The elimination of the DATA 2000 (X) waiver was the removal of a potential barrier to increased buprenorphine use, said Dr. Strayer. “Now that the DATA 2000 (X) waiver has been eliminated, the focus of buprenorphine access is educating primary care and inpatient providers on its use, so that patients with OUD [opioid use disorder] can be treated, regardless of the venue at which they seek care,” he said.
Looking ahead, “The priority in buprenorphine research is determining the most effective way to initiate buprenorphine without the risk of precipitated withdrawal,” Dr. Strayer added.
The study was supported in part by the Benter Foundation, the Michigan Department of Health and Human Services, and the Susan B. Meister Child Health Evaluation and Research Center in the department of pediatrics at the University of Michigan. Dr. Chua was supported by the National Institute on Drug Abuse. Dr. Strayer has disclosed no relevant financial relationships.

Opioid overdose deaths are at a record high in the United States, and many of these deaths can be prevented with medications such as buprenorphine, said lead author Kao-Ping Chua, MD, of the University of Michigan, Ann Arbor, in an interview. “However, buprenorphine cannot prevent opioid overdose deaths if patients are never started on the medication or only stay on the medication for a short time. For that reason, rates of buprenorphine initiation and retention are critical metrics for measuring how well the U.S. health care system is responding to the opioid epidemic,” he said.
“At the time we started our study, several other research groups had evaluated U.S. rates of buprenorphine initiation and retention using data through 2020. However, more recent national data were lacking,” Dr. Chua told this news organization. “We felt that this was an important knowledge gap given the many changes in society that have occurred since 2020,” he noted. “For example, it was possible that the relaxation of social distancing measures during 2021 and 2022 might have reduced barriers to health care visits, thereby increasing opportunities to initiate treatment for opioid addiction with buprenorphine,” he said.
Dr. Chua and colleagues used data from the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed from retail pharmacies in the United States. “Buprenorphine products included immediate-release and extended-release formulations approved for opioid use disorder but not formulations primarily used to treat pain,” they write.
Monthly buprenorphine initiation was defined as the number of patients initiating therapy per 100,000 individuals. For retention, the researchers used a National Quality Forum-endorsed quality measure that defined retention as continuous use of buprenorphine for at least 180 days.
A total of 3,006,629 patients began buprenorphine therapy during the study period; approximately 43% were female.
During the first years of the study period, from January 2016 through September 2018, the monthly buprenorphine initiation rate increased from 12.5 per 100,000 to 15.9 per 100,000, with a statistically significant monthly percentage change of 0.62% (P < .001).
However, from October 2018 through October 2022, the monthly percentage remained essentially the same (P = .62) with a monthly percentage change of −0.03%.
From March 2020 through December 2020, the median monthly buprenorphine initiation rate was 14.4 per 100,000, only slightly lower than the rates from January 2019 through February 2020 and from January 2021 through October 2022 (15.5 per 100,000 and 15.0 per 100,000, respectively).
Over the entire study period from January 2016 through October 2022, the median monthly retention rate for buprenorphine use was 22.2%. This rate increased minimally, with no significant changes in slope and a monthly percentage change of 0.08% (P = .04).
The study findings were limited by several factors, including a lack of data on race and ethnicity, in-clinic administration of buprenorphine, and buprenorphine dispensing through methadone outpatient programs, the researchers note. Also, data did not indicate whether some patients began buprenorphine to treat pain, they say. The timing of the flattening of buprenorphine use also suggests the influence of factors beyond the COVID-19 pandemic, they write.
However, the results were strengthened by the large sample size and suggest that efforts to date to increase buprenorphine use have been unsuccessful, the researchers write. “A comprehensive approach is needed to eliminate barriers to buprenorphine initiation and retention, such as stigma and uneven access to prescribers,” they conclude.
Study highlights underuse of buprenorphine option
“Our study shows that buprenorphine initiation rates have been flat since the end of 2018 and that rates of 180-day retention in buprenorphine therapy have remained low throughout 2016-2022,” Dr. Chua told this news organization. “Neither of these findings are particularly surprising, but they are disappointing,” he said. “There were a lot of policy and clinical efforts to maintain and expand access to buprenorphine during the COVID-19 pandemic, such as allowing buprenorphine to be prescribed via telehealth without an in-person visit and eliminating training requirements for the waiver that previously was required to prescribe buprenorphine.
“The fact that buprenorphine initiation and retention did not rise after these efforts were implemented suggests that they were insufficient to meet the rising need for this medication,” he said.
The current study “adds to a growing body of research suggesting that clinicians are not maximizing opportunities to initiate buprenorphine treatment among patients with opioid addiction,” Dr. Chua said. He cited another of his recent studies in which 1 in 12 patients were prescribed buprenorphine within 30 days of an emergency department visit for opioid overdose from August 2019 to April 2021, but half of patients with emergency department visits with anaphylaxis were prescribed anepinephrine auto-injector.
“My hope is that our new study will further underscore to clinicians how much the health care system is underusing a critical tool to prevent opioid overdose deaths,” he said.
The federal government’s recent elimination of the waiver needed to prescribe buprenorphine may move the needle, but to what degree remains to be seen, Dr. Chua added. “It is possible this intervention will be insufficient to overcome the many other barriers to buprenorphine initiation and retention, such as stigma about the drug among clinicians, patients, and pharmacists,” he said.
Lack of education remains a barrier to buprenorphine use
The current study is important to determine whether attempts to increase buprenorphine initiation and treatment retention are working, said Reuben J. Strayer, MD, director of addiction medicine in the emergency medicine department at Maimonides Medical Center, New York, in an interview.
Dr. Strayer was not involved in the current study, but said he was surprised that initiation of buprenorphine didn’t decrease more dramatically during the pandemic, given the significant barriers to accessing care during that time.
However, “efforts to increase buprenorphine initiation and retention have not been sufficiently effective,” Dr. Strayer said. “The rise of fentanyl as a primary street opioid, replacing heroin, has dissuaded both patients and providers from initiating buprenorphine for fear of precipitated withdrawal.”
The elimination of the DATA 2000 (X) waiver was the removal of a potential barrier to increased buprenorphine use, said Dr. Strayer. “Now that the DATA 2000 (X) waiver has been eliminated, the focus of buprenorphine access is educating primary care and inpatient providers on its use, so that patients with OUD [opioid use disorder] can be treated, regardless of the venue at which they seek care,” he said.
Looking ahead, “The priority in buprenorphine research is determining the most effective way to initiate buprenorphine without the risk of precipitated withdrawal,” Dr. Strayer added.

UTI imaging falls short in some primary care settings
WASHINGTON –
“Timely imaging is recommended after febrile UTI (fUTI) in young children to identify treatable urologic conditions,” wrote Jonathan Hatoun, MD, of Boston Children’s Hospital, and colleagues in a poster presented at the Pediatric Academic Societies annual meeting.
The American Academy of Pediatrics (AAP) currently recommends renal-bladder ultrasound (RBUS) after fUTI with voiding cystourethrogram (VCUG) after abnormal RBUS or second fUTI, but data on clinician adherence to these recommendations are limited, the researchers said.
To characterize practice patterns regarding fUTI, the researchers reviewed data from children younger than 24 months of age with fUTI who were treated at a primary care network in Massachusetts in 2019. The definition of fUTI was temperature of 38° C or higher, positive urinalysis, and more than 50,000 CFU on urine culture. The median age of the patients was 9 months; 84% were female.
In a multivariate analysis, post-UTI imaging followed the AAP guidelines in 82 cases (69.5%). The main reasons for nonadherence were lack of RBUS in 21 patients, VCUG despite normal RBUS in 9 patients, no VCUG after abnormal RBUS in 4 patients, and no VCUG after a second fUTI in 2 patients.
Overall, nonadherence was a result of not ordering a recommended study in 23% of cases (errors of omission) and ordering an unnecessary study in 8% of cases (errors of commission).
Commercial insurance, larger number of providers in practice, and younger provider age were significant independent predictors of adherence (odds ratios 2.82, 1.38, and 0.96, respectively).
The findings were limited by the use of data from a single center; however, the results suggest that targeted training may improve guideline adherence, the researchers wrote. Additional research and quality improvement studies are needed to understand and address the impact of insurance on guideline adherence for imaging after febrile UTIs, they noted.
Provider education is essential to continued quality of care
When it comes to febrile UTIs, “it is important to stay focused on the quality of care being provided, as opposed to the usual benchmark of quantity of care,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, said in an interview.
“This is a very simple but interesting study on provider compliance with practice guidelines,” said Dr. Joos, who was not involved in the study. “I was surprised that the providers did so well in ordering the correct imaging in 70% of the cases,” he said.
Of particular interest, Dr. Joos noted, was that “the authors also showed that older providers and those working in smaller practices are less likely to comply with this particular imaging guideline. This can be summed up as the ‘I didn’t know the guideline’ effect.”
To improve quality of care, “more research and effort should be directed at updating providers when strong new evidence changes previous practices and guidelines,” Dr. Joos told this news organization.
The study received no outside funding. The researchers and Dr. Joos had no financial conflicts to disclose.

Cycle timing may reduce hormonal dosage for contraception
Progesterone and estrogen are often used for contraception by preventing ovulation, but the adverse effects associated with large doses of these hormones remain a concern, wrote Brenda Lyn A. Gavina, a PhD candidate at the University of the Philippines Diliman, Quezon City, and colleagues.
In a study published in PLoS Computational Biology, the researchers examined how the timing of hormone administration during a cycle might impact the amount of hormones needed for contraception. Previous research shown that combining hormones can reduce the dosage needed, but the impact of timing on further dose reduction has not been well studied, they said.
The researchers applied optimal control theory in a mathematical model to show the contraceptive effect of estrogen and/or progesterone at different times in the menstrual cycle. The model was based on a normal menstrual cycle with pituitary and ovarian phases. The model assumed that synthesis of luteinizing hormone and follicle-stimulating hormone occurs in the pituitary, that LH and FSH are held in reserve before release into the bloodstream, and that the follicular/luteal mass goes through nine ovarian stages of development. The model also included the activity of ovarian hormones estradiol (E2), progesterone (P4), and inhibin (Inh), in a normal cycle. In the model, LH, FSH, and E2 peaked in the late follicular phase, and P4 and Inh peaked in the luteal phase.
The pituitary model predicted the synthesis, release, and clearance of LH and FSH, and the response of the pituitary to E2, P4, and Inh. The ovarian model predicted the response of E2, P4, and Inh as functions of LH and FSH.
The researchers simulated a constant dose of exogenous progesterone monotherapy and combined exogenous estrogen/progesterone. They determined that a P4 peak of 4.99 ng/mL was taken as the optimum constant dosage for progesterone monotherapy, and for combination estrogen/progesterone.
The researchers then assessed the impact of time on dosage. They found that estrogen administration starting on the first day of a normal cycle preventing FHS from reaching maximum value, and that the low level of FHS in the follicular phase and additional P4 inhibition slowed follicular growth, and use of combination estrogen/progesterone caused similar inhibition at a later follicular stage.
“The combination therapy suggests that time-varying doses of estrogen and progesterone given simultaneously from the start to the end of the 28-day period, only requires a surge in estrogen dose around the 12th day of the cycle (a delayed administration compared to the estrogen monotherapy),” they noted.
With attention to timing, the maximum progesterone levels throughout a menstrual cycle were 4.43 ng/mL, 4.66 ng/mL, and 4.31 ng/mL for estrogen monotherapy, progesterone monotherapy, and combination therapy, respectively. Total doses of the optimal exogenous hormone were 77.76 pg/mL and 48.84 ng/mL for estrogen and progesterone monotherapy, respectively, and 35.58 pg/mL and 21.67 ng/mL for estrogen and progesterone in combination.
The findings were limited by the use of a standard model that does not account for variations in cycle length, the researchers noted. However, the results reflect other studies of hormonal activity, and the model can be used in future studies of the effect of hormones on cycle length, they said.
Overall, the researchers determined that timing dosage with estrogen monotherapy based on their model could provide effective contraception with about 92% of the minimum total constant dosage, while progesterone monotherapy would be effective with approximately 43% of the total constant dose.
Although more work is needed, the current study results may guide clinicians in experimenting with the optimal treatment regimen for anovulation, the researchers said.
“The results presented here give insights on construction of timed devices that give contraception at certain parts of the menstrual cycle,” they concluded.
Model aims to improve women’s control of contraception
“Aside from wanting to contribute to controlling population growth, we aim to empower women more by giving them more control on when to conceive and start motherhood,” and be in control of contraception in a safer way, said lead author Ms. Gavina, in an interview. In addition, studies are showing the noncontraceptive benefits of suppressing ovulation for managing premenstrual syndromes such as breast tenderness and irritability, and for managing diseases such as endometriosis, she said. “Anovulation also lowers the risk of ACL injuries in female athletes,” she added.
Ms. Gavina said that she was surprised primarily by the optimal control result for estrogen monotherapy. “It was surprising that, theoretically, our mathematical model, with the simplifying assumptions, showed that as low as 10% of the total dose in constant administration could achieve contraception as long as the administration of this dosage is perfectly timed, and the timing was also shown in our optimization result,” she said.
“Our model does not capture all factors in contraception, since the reproductive function in women is a very complex multiscale dynamical system highly dependent on both endogenous and exogenous hormones,” Ms. Gavina told this news organization. However, “with the emergence of more data, it can be refined to address other contraception issues. Further, although the results of this study are not directly translatable to the clinical setting, we hope that these results may aid clinicians in identifying the minimum dose and treatment schedule for contraception,” she said.
Future research directions include examining within and between women’s variabilities and adding a pharmacokinetics model to account for the effects of specific drugs, she said. “We also hope to expand or modify the current model to investigate reproductive health concerns in women, such as [polycystic ovary syndrome] and ovarian cysts,” she added.
Ms. Gavina disclosed support from the University of the Philippines Office of International Linkages, a Continuous Operational and Outcomes-based Partnership for Excellence in Research and Academic Training Enhancement grant, and a Commission on Higher Education Faculty Development Program-II scholarship.

Meditation curbs stress, depression as adjunct to CAD rehab
Regular meditation reduced depression by roughly 44% in adults with coronary artery disease who were involved in a cardiovascular rehabilitation program.
An increasing body of research supports the impact of psychological risk factors including stress, personality type, anger, and hostility on conditions such as depression and anxiety, but also social isolation and low socioeconomic status, Ana Luisa Vitorino Monteiro, MD, of the University of Lisbon said in a presentation at the annual congress of the European Association of Preventive Cardiology. In addition, “stress, anxiety, and depression deteriorate the cardiovascular (CV) system through psycho-neuro-immunoendocrinology system and behavioral pathways.”
Meditation as a tool for stress management has been gaining popularity, but its use as part of a CV rehabilitation program as a complementary therapy has not been well studied, she added.
Dr. Monteiro and colleagues recruited 80 adults with CAD who were undergoing CV rehabilitation to join a meditation program. Of these, 48 accepted (60%) and 40% declined. Those who accepted were part of an exercise-based CV rehabilitation program that met three times a week for at least 6 months. The mean age of the participants was 65 years, and 80% were male.
Participants were randomized to an intervention group with a weekly 90-minute session that included breathing and meditation for 1 month in addition to usual care, or to usual care in the rehabilitation program. Over the next 3 months, the intervention patients were encouraged to practice daily meditation for 20 minutes alone or using video support material, with a weekly follow-up phone call. Assessments of stress, anxiety, and depression took place at baseline and after 4 months using the Perceived Stress Scale, Beck Anxiety Inventory, Beck Depression Inventory, and HeartQoL questionnaire.
At 4 months, individuals in the meditation group had reduced depression levels significantly, by 44%, compared with controls (P < .001). Anxiety and stress decreased significantly, by 30% (P = .04) and 31% (P = .05), respectively. After 4 months, individuals in the control group were offered the opportunity to follow the meditation protocol.
In addition, “the emotional dimension of quality of life increased by 60% in the intervention group,” Dr. Monteiro noted. However, physical QoL did not change between groups.
The study was limited by the small sample size, and more research is needed in larger and more diverse populations, Dr. Monteiro said. However, the results support the value of meditation as an adjunct component of care for CAD patients in a long-term rehabilitation program.
Motivation makes a difference
The current study is important as an exploration of “a straightforward, simple, low-risk approach that could be an adjunct to benefit patients with serious cardiovascular disease,” Brian Olshansky, MD, a cardiologist at the University of Iowa, Iowa City, said in an interview.
“We have moved into a time of polypharmacy and multiple interventions for patients with underlying cardiovascular disease which, in many cases, have proven benefit but also potential adverse effects,” he said. “Engaging patients to participate in their health care, when there is serious underlying cardiovascular disease, has potential beneficial impact in many ways. Meditation is a low-risk, low-cost, potentially beneficial adjunct to standard medical therapy that may enhance psychological outcomes as shown here in this small study.”
However, “patients often rely on high-cost, potentially high-risk therapeutic interventions, expecting complete control of their problems without their own collaborative intervention,” he noted.
Dr. Olshansky said he was not surprised by any of the findings, and would have been surprised if meditation had failed to show any benefit for the study population.
“I am very pleased to see these results and would encourage meditation practice to be part of cardiovascular rehabilitation for motivated individuals,” he said. “What did surprise me was the adherence to the meditation protocol for those who participated. This represents a highly motivated group and it may be difficult to expect the same results in less motivated individuals.”
The current study has several strengths, including the use of controls and high rates of adherence to the protocol, said Dr. Olshansky. Other strengths include the standardized approach and the reasonable quality of the outcome measures, which showed a substantial benefit.
However, “this is a small study of motivated individuals of whom 80% were male,” and generalizability to other populations is unclear, Dr. Olshansky said. In addition, the racial mix was not described, and the severity of the underlying coronary artery disease and the therapies provided to these individuals is not detailed. A sicker population may not fare as well.”
The reasons for the benefits of meditation remain uncertain, Dr. Olshansky said. “It could be, specifically, that the meditation itself has physiological effects that ultimately translate into psychosocial benefit. However, those who enrolled and were interested may have derived a placebo effect. In any case, benefit was achieved, but the crossover benefit to the control group is unclear.
“In other words, the statistical approach to benefit is uncertain as to when it was measured, but presumably before the control group was allowed to engage in a meditation practice,” and the follow-up was short term, said Dr. Olshansky.
Data support patient engagement
The message to clinicians and patients: “Patients should be engaged in their own health care when it comes to rehabilitation for cardiovascular disease,” said Dr. Olshansky. “Motivated individuals who are educated about a meditative practice performed in a standardized way will have improvement most likely in their quality of life, and when it comes to measurements of depression, stress and anxiety.”
Although the mechanisms behind the benefits remain unclear, “having a standardized credible prescription for which patients can become intimately engaged is beneficial,” he added.
The study received no outside funding. Neither Dr. Monteiro nor Dr. Olshansky had any financial conflicts to disclose.
Regular meditation reduced depression by roughly 44% in adults with coronary artery disease who were involved in a cardiovascular rehabilitation program.
An increasing body of research supports the impact of psychological risk factors including stress, personality type, anger, and hostility on conditions such as depression and anxiety, but also social isolation and low socioeconomic status, Ana Luisa Vitorino Monteiro, MD, of the University of Lisbon said in a presentation at the annual congress of the European Association of Preventive Cardiology. In addition, “stress, anxiety, and depression deteriorate the cardiovascular (CV) system through psycho-neuro-immunoendocrinology system and behavioral pathways.”
Meditation as a tool for stress management has been gaining popularity, but its use as part of a CV rehabilitation program as a complementary therapy has not been well studied, she added.
Dr. Monteiro and colleagues recruited 80 adults with CAD who were undergoing CV rehabilitation to join a meditation program. Of these, 48 accepted (60%) and 40% declined. Those who accepted were part of an exercise-based CV rehabilitation program that met three times a week for at least 6 months. The mean age of the participants was 65 years, and 80% were male.

Napping and AFib risk: The long and the short of it
Napping for more than half an hour during the day was associated with a 90% increased risk of atrial fibrillation (AFib), but shorter naps were linked to a reduced risk, based on data from more than 20,000 individuals.
“Short daytime napping is a common, healthy habit, especially in Mediterranean countries,” Jesus Diaz-Gutierrez, MD, of Juan Ramon Jimenez University Hospital, Huelva, Spain, said in a presentation at the annual congress of the European Association of Preventive Cardiology (EAPC).
Previous studies have shown a potential link between sleep patterns and AFib risk, but the association between specific duration of daytime naps and AFib risk has not been explored, he said.
Dr. Diaz-Gutierrez and colleagues used data from the University of Navarra Follow-up (SUN) Project, a prospective cohort of Spanish university graduates, to explore the possible link between naps and AFib. The study population included 20,348 individuals without AFib at baseline who were followed for a median of 13.8 years. The average age of participants at baseline was 38 years; 61% were women.
Daytime napping patterns were assessed at baseline, and participants were divided into nap groups of short nappers (defined as less than 30 minutes per day), and longer nappers (30 minutes or more per day), and those who reported no napping.
The researchers identified 131 incident cases of AFib during the follow-up period. Overall, the relative risk of incident AFib was significantly higher for the long nappers (adjusted hazard ratio 1.90) compared with short nappers in a multivariate analysis, while no significant risk appeared among non-nappers compared to short nappers (aHR 1.26).
The researchers then excluded the non-nappers in a secondary analysis to explore the impact of more specific daily nap duration on AFib risk. In a multivariate analysis, they found a 42% reduced risk of AF among those who napped for less than 15 minutes, and a 56% reduced risk for those who napped for 15-30 minutes, compared with those who napped for more than 30 minutes (aHR 0.56 and 0.42, respectively).
Potential explanations for the associations include the role of circadian rhythms, Dr. Diaz-Gutierrez said in a press release accompanying the presentation at the meeting. “Long daytime naps may disrupt the body’s internal clock (circadian rhythm), leading to shorter nighttime sleep, more nocturnal awakening, and reduced physical activity. In contrast, short daytime napping may improve circadian rhythm, lower blood pressure levels, and reduce stress.” More research is needed to validate the findings and the optimum nap duration, and whether a short nap is more advantageous than not napping in terms of AFib risk reduction, he said.
The study results suggest that naps of 15-30 minutes represent “a potential novel healthy lifestyle habit in the primary prevention of AFib,” Dr. Diaz-Gutierrez said in his presentation. However, the results also suggest that daily naps be limited to less than 30 minutes, he concluded.
Sleep habits may serve as red flag
“As we age, most if not all of us will develop sleep disturbances, such as insomnia, obstructive sleep apnea (OSA), and other sleep issues,” Lawrence S. Rosenthal, MD, of the University of Massachusetts, Worcester, said in an interview.
Therefore, “this study is near and dear to most people, and most would agree that poor sleeping habits affect our health.” In particular, OSA has been linked to AFib, although that was not measured in the current study, he added.
Dr. Rosenthal said he was not surprised by the current study findings. “It seems that a quick recharge of your ‘battery’ during the day is healthier than a long, deep sleep daytime nap,” he said. In addition, “Longer naps may be a marker of OSA,” he noted.
For clinicians, the take-home message of the current study is the need to consider underlying medical conditions in patients who regularly take long afternoon naps, and to consider these longer naps as a potential marker for AFib, said Dr. Rosenthal.
Looking ahead, a “deeper dive into the makeup of the populations studied” would be useful as a foundation for additional research, he said.
The SUN Project disclosed funding from the Spanish Government-Instituto de Salud Carlos III and the European Regional Development Fund (FEDER), the Navarra Regional Government, Plan Nacional Sobre Drogas, the University of Navarra, and the European Research Council. The researchers, and Dr. Rosenthal, had no financial conflicts to disclose.

Premenopausal women benefit from ovarian conservation with benign hysterectomies
Although bilateral salpingo-oophorectomy (BSO) with hysterectomy has been shown to reduce the risk for ovarian cancer in women at increased risk, current guidelines are touting ovarian conservation, especially in premenopausal women, wrote Mathilde Gottschau, MD, of the Danish Cancer Society Research Center, Copenhagen, and colleagues. However, post-hysterectomy outcomes in women with and without BSO have not been well examined.
In a study published in the Annals of Internal Medicine, the researchers reviewed data from a nationwide registry of women in Denmark aged 20 years and older who underwent benign hysterectomies with BSO (22,974 women) and without BSO (120,011 women) between 1977 and 2017. The women were divided into subgroups based on age; those younger than 45 years were defined as premenopausal, those aged 45-54 years were defined as perimenopausal, those aged 55-64 were defined as early postmenopausal, and those aged 65 and older were defined as late menopausal.
The primary outcomes were hospitalization for cardiovascular disease, cancer incidence, and all-cause mortality over a median follow-up period of 22 years.
For women younger than 45 years, the 10-year cumulative risk for all cancer was lower with BSO than without, but the risk of overall cardiovascular disease was higher with BSO, with higher levels of ischemic heart disease and stroke, compared with women without BSO. The 10-year cumulative mortality was higher with BSO than without (2.16% vs. 1.94%).
For women aged 45-54 years, the 10-year cumulative cancer risk was higher in those with BSO than those without BSO (risk difference, 0.73 percentage points) associated mainly with nonbreast cancer, and both 10-year and 20-year mortality were higher in those with BSO than those without.
For women aged 55-65 years, the 10-year cumulative cancer risk was higher in those with BSO than those without BSO. Cumulative overall mortality was higher at 10 years for those with BSO, but lower at 20 years.
For women aged 65 years and older, both 10-year and 20-year cumulative overall cancer risk was higher with BSO than without (RD, 2.54 and 4.57 percentage points, respectively). Cumulative mortality was higher in the BSO group at 10 years, but lower at 20 years.
The study findings were limited by several factors including the use of age to determine menopausal status and the lack of genetic predisposition data, and the focus only on a relatively homogeneous population that may not be generalizable to other populations, the researchers noted.
However, the results were strengthened by the use of a nationwide registry and the long-term follow-up period, they said. The current study indicates that the health risks outweigh the potential benefits of BSO with benign hysterectomy for premenopausal women and supports the current guidelines for ovarian conservation in these women with low lifetime ovarian cancer risk, they said. For postmenopausal women, the data support a cautious approach to BSO given the lack of a clear survival benefit and cancer excess, they concluded.
Delayed diagnosis of ovarian cancers favors BSO
“The question of removing ovaries at the time of benign hysterectomy to prevent ovarian cancer in low-risk women has been widely debated,” which has contributed to the variation in incidence rates of unilateral and bilateral oophorectomy over time, wrote Elizabeth Casiano Evans, MD, of the University of Texas, San Antonio, and Deslyn T.G. Hobson, MD, of Wayne State University, Detroit, in an accompanying editorial.
Ovarian cancer often goes undiagnosed until an advanced stage, and BSO can significantly reduce risk in women with BRCA1 and BRCA2 mutations, they noted.
For women without increased risk, those who are premenopausal may wish to preserve ovarian function, but women also may benefit from improvements in a range of menopause-related symptoms including vasomotor and urogenital symptoms, sexual dysfunction, and psychiatric and cognitive symptoms, they said.
“In addition, salpingectomy alone has a role in significantly reducing ovarian cancer incidence without compromising ovarian function because the fallopian tube has been found to be at the origin of many ovarian cancer cases,” they noted. In the current study, “the crude ovarian cancer risk was lower with BSO” across all age groups, the editorialists said.
The choice of whether to include BSO at the time of benign hysterectomy is complicated, with many factors to consider, the editorialists wrote, and the current study supports the need for informed, shared decision-making between clinicians and patients.
The study was supported by the Danish Cancer Society’s Scientific Committee and the Mermaid Project. The researchers had no financial conflicts to disclose. The editorial authors had no financial conflicts to disclose.

For women aged 55-65 years, the 10-year cumulative cancer risk was higher in those with BSO than those without BSO. Cumulative overall mortality was higher at 10 years for those with BSO, but lower at 20 years.
For women aged 65 years and older, both 10-year and 20-year cumulative overall cancer risk was higher with BSO than without (RD, 2.54 and 4.57 percentage points, respectively). Cumulative mortality was higher in the BSO group at 10 years, but lower at 20 years.
The study findings were limited by several factors including the use of age to determine menopausal status and the lack of genetic predisposition data, and the focus only on a relatively homogeneous population that may not be generalizable to other populations, the researchers noted.
However, the results were strengthened by the use of a nationwide registry and the long-term follow-up period, they said. The current study indicates that the health risks outweigh the potential benefits of BSO with benign hysterectomy for premenopausal women and supports the current guidelines for ovarian conservation in these women with low lifetime ovarian cancer risk, they said. For postmenopausal women, the data support a cautious approach to BSO given the lack of a clear survival benefit and cancer excess, they concluded.
Delayed diagnosis of ovarian cancers favors BSO
“The question of removing ovaries at the time of benign hysterectomy to prevent ovarian cancer in low-risk women has been widely debated,” which has contributed to the variation in incidence rates of unilateral and bilateral oophorectomy over time, wrote Elizabeth Casiano Evans, MD, of the University of Texas, San Antonio, and Deslyn T.G. Hobson, MD, of Wayne State University, Detroit, in an accompanying editorial.
Ovarian cancer often goes undiagnosed until an advanced stage, and BSO can significantly reduce risk in women with BRCA1 and BRCA2 mutations, they noted.
For women without increased risk, those who are premenopausal may wish to preserve ovarian function, but women also may benefit from improvements in a range of menopause-related symptoms including vasomotor and urogenital symptoms, sexual dysfunction, and psychiatric and cognitive symptoms, they said.
“In addition, salpingectomy alone has a role in significantly reducing ovarian cancer incidence without compromising ovarian function because the fallopian tube has been found to be at the origin of many ovarian cancer cases,” they noted. In the current study, “the crude ovarian cancer risk was lower with BSO” across all age groups, the editorialists said.
The choice of whether to include BSO at the time of benign hysterectomy is complicated, with many factors to consider, the editorialists wrote, and the current study supports the need for informed, shared decision-making between clinicians and patients.
The study was supported by the Danish Cancer Society’s Scientific Committee and the Mermaid Project. The researchers had no financial conflicts to disclose. The editorial authors had no financial conflicts to disclose.
Although bilateral salpingo-oophorectomy (BSO) with hysterectomy has been shown to reduce the risk for ovarian cancer in women at increased risk, current guidelines are touting ovarian conservation, especially in premenopausal women, wrote Mathilde Gottschau, MD, of the Danish Cancer Society Research Center, Copenhagen, and colleagues. However, post-hysterectomy outcomes in women with and without BSO have not been well examined.
In a study published in the Annals of Internal Medicine, the researchers reviewed data from a nationwide registry of women in Denmark aged 20 years and older who underwent benign hysterectomies with BSO (22,974 women) and without BSO (120,011 women) between 1977 and 2017. The women were divided into subgroups based on age; those younger than 45 years were defined as premenopausal, those aged 45-54 years were defined as perimenopausal, those aged 55-64 were defined as early postmenopausal, and those aged 65 and older were defined as late menopausal.
The primary outcomes were hospitalization for cardiovascular disease, cancer incidence, and all-cause mortality over a median follow-up period of 22 years.
For women younger than 45 years, the 10-year cumulative risk for all cancer was lower with BSO than without, but the risk of overall cardiovascular disease was higher with BSO, with higher levels of ischemic heart disease and stroke, compared with women without BSO. The 10-year cumulative mortality was higher with BSO than without (2.16% vs. 1.94%).
For women aged 45-54 years, the 10-year cumulative cancer risk was higher in those with BSO than those without BSO (risk difference, 0.73 percentage points) associated mainly with nonbreast cancer, and both 10-year and 20-year mortality were higher in those with BSO than those without.
For women aged 55-65 years, the 10-year cumulative cancer risk was higher in those with BSO than those without BSO. Cumulative overall mortality was higher at 10 years for those with BSO, but lower at 20 years.
For women aged 65 years and older, both 10-year and 20-year cumulative overall cancer risk was higher with BSO than without (RD, 2.54 and 4.57 percentage points, respectively). Cumulative mortality was higher in the BSO group at 10 years, but lower at 20 years.

Cardiovascular disease deaths rise on and after high-pollution days
Cardiovascular disease deaths were significantly more common on days of high pollution and for the following 2 days, compared with other days, based on data from nearly 88,000 deaths over a 5-year period.
Previous research has shown the harmful effect of air pollution on human health in highly polluted areas, but Eastern Poland, a region with so-called “Polish smog” has exceptionally high levels of pollution. However, the specific impact of Polish smog, caused primarily by burning coal, on cardiovascular disease (CVD) mortality has not been well studied, said Michal Swieczkowski, MD, of the Medical University of Bialystok (Poland) in a presentation at the annual congress of the European Association of Preventive Cardiology.
Dr. Swieczkowski and colleagues reviewed all-cause deaths from five main cities in Eastern Poland during 2016-2020 for associations with pollution levels and days when deaths occurred. Mortality data were obtained from the Central Statistical Office. Air pollution concentrations for two types of particulate matter (PM2.5, PM10) and nitrogen oxide were collected from the Voivodeship Inspectorate for Environmental Protection. The main sources of the pollutants were road traffic and household heaters using coal or wood.
The final analysis included nearly 6 million person-years of follow-up. The researchers used a time-stratified case-crossover design. For each participant, the researchers compared levels of each pollutant on the day of the week a death occurred (such as a Wednesday) with pollutant levels on the same day of the week without any deaths in the same month (the remaining Wednesdays of that month). This design eliminated the potential confounding effects of participant characteristics, including other cardiovascular risk factors such as smoking and hyperlipidemia, and time trends. Essentially, participants “served as their own controls,” Dr. Swieczkowski said. The researchers conducted similar analyses for pollution levels 1 day and 2 days before a death occurred.
Overall, 87,990 deaths were identified during the study period; of these, 34,907 were from CVD, 9,688 from acute coronary syndromes, and 3,776 from ischemic stroke.
“Exposure to PM2.5 and PM10 was associated with increased mortality on the day of exposure, the next day, and up to 2 days after exposure,” said Dr. Swieczkowski.
Overall, an increase of 10 mcg/m3 in the three pollutants was significantly associated with increase in CVD mortality on the day of exposure to the increased pollution levels, with odds ratios of 1.034, 1.033, and 1.083 for PM2.5, PM10, and NO2, respectively (all P < .001).
The risks of dying from CVD were similar 1 and 2 days after the polluted day.
An increase in PM levels, but not NO2, was significantly associated with acute coronary syndrome (ACS) on the day of exposure to increased pollutants (ORs, 1.029 for PM2.5 [P = .002] and 1.015 [P = .049] for PM10). Both ischemic stroke and ACS mortality were significantly higher at 1 day after exposure, compared with other days. Ischemic stroke was associated with increases in PM2.5 and PM10, while ACS was associated with increases in PM2.5, PM10, and NO2.
When stratified by gender, the effects were more noticeable in women, Dr. Swieczkowski said. “Exposure to both types of particulate caused increased mortality due to acute coronary syndrome as well as ischemic stroke.” Among men, only death from acute coronary syndrome was significantly associated with exposure to increased particulate matter.
In a head-to-head comparison, women were more vulnerable to air pollution by up to 2.5%, he added.
When stratified by age, the effects of all three pollutants were associated with increased risk of death from ischemic stroke and ACS in participants older than 65 years. For those aged 65 years and younger, the only significant association was between ACS-associated mortality and ischemic stroke.
The results suggest “a special need for developing calculators to estimate the risk of CVD incidence depending on the place of residence that could be used for everyday practice,” said Dr. Swieczkowski. “Systemic changes should become a priority for policy makers, and, simultaneously, we as physicians should educate and protect our patients, especially those with high risk of cardiovascular disease,” he said.
Gender differences rooted in anatomy
When asked for an explanation of the difference in the impact of pollution on mortality between men and women, Dr. Swieczkowski explained that women are likely more vulnerable because of differences in anatomy of the pharynx and larynx, and breathing patterns. Previous studies have shown that air pollution causes more oxidative stress in women. Also, in the current study, the mean age of the women was 8 to 9 years older, he said.
The study design was an “elegant way to take away the impact of other cardiovascular risk factors,” noted session moderator Maryam Kavousi, MD, of Erasmus University Medical Center, Rotterdam, the Netherlands.
The study was supported by the National Science Centre, Poland. The researchers had no financial conflicts to disclose.

Sentinel events in hospitals continue to rise, driven by increase in falls
Reporting sentinel events to The Joint Commission began in 1996 as a way to help health care organizations improve safety. The annual review is based on an aggregate database of reports analyzed each year, according to the review authors.
The Joint Commission defines a sentinel event as a patient safety event (not primarily related to the natural course of the patient’s illness or underlying condition) that reaches a patient and results in death, permanent harm (regardless of severity), or severe harm (regardless of duration).
Some of the specific events deemed sentinel include patient suicide while under care in a health care setting, unanticipated death of a full-term infant, homicide of any patient or staff member while on site at a health care organization, any intrapartum maternal death, severe maternal morbidity, sexual abuse or assault of any patient undergoing care in the health care setting, sexual abuse or assault of any staff member providing care, and physical assault of any patient or staff member in the health care setting.
Additional events considered sentinel are related to treatments and procedures. These include surgery in the wrong site; wrong patient or wrong procedure for a given patient; administration of blood or blood products incompatible with the patient that results in death, permanent harm, or severe harm; severe neonatal hyperbilirubinemia; and patient falls.
A total of 1,441 sentinel events were reported in 2022. Patient falls accounted for the majority (42%) of these events, continuing a trend in increasing rates of patient falls from previous years. Falls considered sentinel events were those resulting in any fracture, surgery, casting or traction, consultation or comfort care for neurologic or internal injury, the need for blood products, or death or permanent harm as a result of injuries sustained in the fall. The leading sentinel event types after falls included delay in treatment, unintended retention of a foreign object, and wrong surgery (6% for each). Other sentinel event types in the top 10 accounted for 5% or less of reports: suicide (5%), assault/rape/sexual assault/homicide (4%), fire/burns (3%), perinatal events (2%), self-harm (2%), and medication management (2%).
Overall, 20% of the 2022 events resulted in patient death, 6% in permanent harm or loss of function, 44% in severe temporary harm, and 13% in a need for additional care or an extended hospital stay.
The most common events that led to patient death were suicide (24%), treatment delays (21%), and patient falls (11%). Patient falls also accounted for nearly two-thirds of the events resulting in severe temporary harm (62%).
Most of the events (88%) occurred in hospital settings; of these, the most common were falls (45%), followed by the retention of foreign objects and incorrect surgeries (7% and 6%, respectively). Overall, 90% of sentinel events were reported by the health care organizations; the remaining 10% were reported by patients, families, or employees (current or former).
“Failures in communication, teamwork, and consistently following policies were leading causes for reported sentinel events,” the authors wrote. However, reporting sentinel events is voluntary; therefore “no conclusions should be drawn about the actual relative frequency of events or trends in events over time,” they noted.
Increased reporting may not reflect increased occurrence
“It is important to clarify that The Joint Commission saw an increase in reporting of sentinel events; whether this is indicative of an actual increase in occurrence of sentinel events across the country or not is difficult to say, as the reporting is voluntary,” said Haytham Kaafarani, MD, MPH, chief patient safety officer and medical director for The Joint Commission, in an interview.
“However, this is the highest number reported to The Joint Commission since the inception of the sentinel event policy: there were 547 health care organizations that reported sentinel events in 2022, compared to 500 in 2021 and 423 in 2020,” Dr. Kaafarani said. “Having said that, based on published literature, the COVID-19 pandemic stressed our health care systems in many ways including but not limited to staff shortage in times of increased needs, worsening of mental health conditions, and delay in presentation of non–COVID-related medical conditions during the pandemic,” he noted.
Dr. Kaafarani said that The Joint Commission was not surprised by the type of sentinel events reported, which has remained consistent with previous years.
However, The Joint Commission was surprised by the significant increase in the number of reported events, he said. “Since reporting is voluntarily, we welcome the increase in reporting of sentinel events, as it helps The Joint Commission better understand the patient safety landscape across the country, and better helps health care organizations during their difficult times.”
Based on the latest information, “The Joint Commission encourages health care organizations to create research that is focused on preventing patient falls in hospitals,” said Dr. Kaafarani. “With staff shortages reported within many health care organizations, it is now more essential than ever to establish systematic interventions to prevent patient falls and resultant harm.”

The most common events that led to patient death were suicide (24%), treatment delays (21%), and patient falls (11%). Patient falls also accounted for nearly two-thirds of the events resulting in severe temporary harm (62%).
Most of the events (88%) occurred in hospital settings; of these, the most common were falls (45%), followed by the retention of foreign objects and incorrect surgeries (7% and 6%, respectively). Overall, 90% of sentinel events were reported by the health care organizations; the remaining 10% were reported by patients, families, or employees (current or former).
“Failures in communication, teamwork, and consistently following policies were leading causes for reported sentinel events,” the authors wrote. However, reporting sentinel events is voluntary; therefore “no conclusions should be drawn about the actual relative frequency of events or trends in events over time,” they noted.
Increased reporting may not reflect increased occurrence
“It is important to clarify that The Joint Commission saw an increase in reporting of sentinel events; whether this is indicative of an actual increase in occurrence of sentinel events across the country or not is difficult to say, as the reporting is voluntary,” said Haytham Kaafarani, MD, MPH, chief patient safety officer and medical director for The Joint Commission, in an interview.
“However, this is the highest number reported to The Joint Commission since the inception of the sentinel event policy: there were 547 health care organizations that reported sentinel events in 2022, compared to 500 in 2021 and 423 in 2020,” Dr. Kaafarani said. “Having said that, based on published literature, the COVID-19 pandemic stressed our health care systems in many ways including but not limited to staff shortage in times of increased needs, worsening of mental health conditions, and delay in presentation of non–COVID-related medical conditions during the pandemic,” he noted.
Dr. Kaafarani said that The Joint Commission was not surprised by the type of sentinel events reported, which has remained consistent with previous years.
However, The Joint Commission was surprised by the significant increase in the number of reported events, he said. “Since reporting is voluntarily, we welcome the increase in reporting of sentinel events, as it helps The Joint Commission better understand the patient safety landscape across the country, and better helps health care organizations during their difficult times.”
Based on the latest information, “The Joint Commission encourages health care organizations to create research that is focused on preventing patient falls in hospitals,” said Dr. Kaafarani. “With staff shortages reported within many health care organizations, it is now more essential than ever to establish systematic interventions to prevent patient falls and resultant harm.”

Adherence to oral contraceptive protocols prevents pregnancy
Combined oral contraceptives (COCs) remain a popular method of pregnancy prevention worldwide, but efficacy and failure rates can be difficult to determine, as real-word use does not always mirror clinical trials, wrote Mitchell D. Creinin, MD, of the University of California, Davis, and colleagues. Clinical trials include perfect use or method-failure rates, but data on pregnancy risk based on reported adherence alone are lacking, they said.
To assess the effects of missed pills on COC efficacy, the researchers reviewed data from a pair of parallel phase 3 trials, focusing only on adherence to the pill dosing regimen. The findings were published in Obstetrics & Gynecology.
The study population included 1,864 individuals from the United States and Canada, and 1,553 from Europe and Russia.
The participants were healthy, sexually active adults aged 16-50 years in monogamous relationships from 2016 through 2018 who agreed to used estetrol 15 mg and drospirenone 3 mg for up to 13 28-day cycles as their only contraceptive method. Condom use was permitted for protection against sexually transmitted infections if needed. The 28-day COCs included 24 hormonal tablets and 4 placebo tablets. Participants received written instructions for what to do it they missed pills.
The primary outcome was the relationship between missed pills and pregnancies.
A total of 31 pregnancies occurred across both studies; none of these occurred during cycles in which other contraception was used. Of 22 pregnancies in participants who reported taking all pills, 21 reported daily pill use during the cycle in which pregnancy occurred. One participant reported not taking one pill and one participant reported not taking two pills; neither correctly followed the instructions for missed pills.
Pregnancies occurred in .09% of cycles in which participants reported taking all pills, and in 0.25%, 0.83%, and 1.6% of cycles in which participants reported missing one pill, two pills, or more than two pills, respectively.
“Pregnancy rates exceeded 1% only in participants who did not correctly follow missed-pill instructions,” the researchers noted.
Pregnancy rates per cycle ranged from 0% to 0.21%, and 48.4% of the pregnancies occurred during the first four cycles of COC use. Approximately one-third (32.3%) of pregnancies occurred within the first week of a new pill pack.
“Fertilization does not appear to be related to the timing of missed pills within the cycle because pregnancy did not occur more frequently earlier in the cycle (after the placebo pills),” the researchers wrote in their discussion. This finding contradicts previous research suggesting that contraceptive failure rates decrease over the first year of use, they said. In addition, the formulation of the pill used may affect pregnancy rates when pills are missed, as some hormones have longer half-lives, they noted.
The study findings were limited by several factors, including the lack of adjustment for outcomes based on reported sexual activity per cycle, and by the reliance on self-reports.
However, the results were strengthened by the use of the clinical outcomes of pregnancy as the primary outcome, rather than characteristics and predictors of participants who missed pills, the researchers said.
The cycle-based methodology used in the current study may provide insight on the relationship between COC adherence and pregnancy risk that can inform future studies, they concluded.
Findings highlight the importance of options
“With increasing restrictions on abortion care, offering more contraceptive options for people is critical,” Lauren Owens, MD, associate professor of obstetrics and gynecology at the University of Washington, Seattle, said in an interview. “That’s not to say that having another pill option makes up for the harm people are experiencing as they navigate abortion bans and legal interference in their health care, but no one pill works for all people, and having more options is helpful,” she said.
Dr. Owens noted that the rates of pregnancy in the current study were lower than she traditionally associates with COCs, “although I usually discuss annual failure rates with patients, not failure rates per cycle, and the latter will clearly be lower.” In the current study, “The authors hypothesize some of this may be due to the longer half-life that estetrol has compared to ethinyl estradiol, the estrogen form more commonly found in oral contraceptive pills,” she said.
From a clinical standpoint, “I appreciated the linkage between number of missed pills and pregnancies occurring,” Dr. Owens said. “This is a good reminder to clinicians to talk to patients ahead of time about what to do when missed pills occur and to provide resources in advance that patients can reference when needed,” she said.
“The authors published other studies on this pill in the last year and it seems to work well and have a reasonable safety profile,” Dr. Owens told this news organization. However, “We still need to broaden the methods available to patients, particularly methods that people producing sperm can use. In the face of ongoing and escalating attacks on access to contraceptive care and abortion care, it’s more important than ever to do what we can to improve options for patients,” she said.

He disclosed serving on the advisory boards for Evofem, Fuji Pharma, Gedeon Richter, GlaxoSmithKline, Mayne, Merck, OLIC, Organon, and Searchlight, and serving as a consultant for Estetra SRL (including the current study), Libbs, Mayne, and Medicines360; his university department receives contraceptive research funding from Chemo Research SL, Evofem, HRA Pharma, Medicines360, Merck, and Sebela. Dr. Owens had no relevant financial conflicts to disclose.
