Cognitive behavioral therapy (CBT) is supported as an effective treatment for depression by clinical practice guidelines from the US Department of Veterans Affairs (VA) and US Department of Defense.^1-3 Despite research supporting the use of evidence-based CBT for anxiety, mood, and emotional disorders, patient access to these interventions is limited.⁴ One barrier to CBT for anxiety, mood, and emotional disorders is the traditional use of single-disorder protocols (SDPs) to separately treat each disorder (eg, major depression, generalized anxiety disorder, panic disorder).

Use of SDPs places a high burden on clinicians, requiring them to learn and competently implement multiple different manualized interventions for each anxiety, mood, or emotional disorder encountered in practice.⁴ It is common for individuals who present with an anxiety, mood, or emotional disorder to experience co-occurring disorders.⁵ Traditional SDP-based CBT may require multiple SDPs to address co-occurring disorders, extending time in treatment and increasing training burden. There is evidence that even when an SDP is used, co-occurring difficulties may decrease in intensity.⁶ Thus, evidence-based CBT for 1 presenting concern may positively affect co-occurring difficulties that are not the primary treatment target.⁶

Unified Protocol (UP) is a transdiagnostic CBT intervention for anxiety and mood disorders. UP targets emotional experiences (eg, negative affect and emotional distress) that are present in multiple anxiety, depression, and emotional disorders. UP is organized into 8 modules and uses interventions present in other CBT SDPs, such as teaching objective assessment methods to clients, motivational enhancement and goal setting, emotion psychoeducation, mindful awareness, cognitive reframing, and exposure principles as mechanisms of change (Table 1).⁴ UP is an ideal intervention for addressing a number of anxiety, mood, and emotional disorders as well as addressing cooccurring disorders within the same course of treatment.

UP has been compared to SDPs; studies illustrate that UP is equivalent to SDPs at the end of treatment and at 6 months posttreatment.^4,7 Additionally, patients who received UP experienced symptom reduction for multiple co-occurring disorders.⁷ Furthermore, patients were less likely to drop out of UP when compared with SDPs.⁴

Studies have reported positive impacts on affective disorders with UP. A 2019 metaanalysis found significant reductions in depression and anxiety-related disorders.⁸ Additionally, UP has been shown to be effective when delivered in person and via telehealth.^9,10 UP has also been successfully used in veterans.¹¹ While traditional models of UP (1-2 sessions weekly) have a lower dropout rate than SDPs, UP and CBT dropout rates still leave room for improvement.^12-14 Specifically, rates of attrition from SDP CBT and transdiagnostic CBT protocols range from 9% to 35%, and dropout reduces the likelihood of attaining a full therapeutic dose of any course of CBT. Notably, accelerated delivery of CBT (ie, ≥3 sessions/wk) has been shown to reduce risk of dropout.^14,15

Veterans are at increased risk for suicide, and anxiety and mood disorders are associated with increased risk of suicide attempt and death.^16,17 Very few veterans who could benefit from high-quality CBT interventions, whether SDP or UP, are able to access them. Only 6.3% of veterans received ≥1 session of an evidence-based CBT SDP for posttraumatic stress disorder (PTSD) at 6 clinics evaluated in 2010.¹⁸

We identified 2 strategies to increase access to and completion of an evidence-based CBT course. First, the use of transdiagnostic UP instead of SDPs reduced burden on therapists and allowed them to address presenting and co-occurring disorders within the same course of care. Second, the use of an accelerated model of service delivery reduced dropout risk. Training clinicians to deliver UP is efficient and cost-effective, considering clinicians use core strategies that can be tailored and flexibly applied to a range of emotional difficulties. Thus, implementing UP may decrease barriers to receiving an optimal dose of an evidence-based CBT delivered with fidelity in a time- and cost-efficient manner.⁴ Two studies have found no evidence of differences in outcomes between UP and SDPs, suggesting that training and supervising clinicians in a single transdiagnostic UP intervention may prepare them to treat heterogeneous and co-occurring anxiety, mood, and emotional disorders with less burden than learning multiple SDPs.^7,19

Delivering UP in an accelerated or massed format (≥4 sessions/wk) instead of the traditional spaced model (1 session/wk) has empirical support but has not been widely implemented. This approach, sometimes referred to as a UP-intensive outpatient program (UP-IOP) or UP-intensive outpatient track (UP-IOT), has been shown to be feasible, acceptable, and effective, with increased completion rates compared with traditional UP delivery (1-2 sessions/wk).^20-22

Ragsdale et al describe a 2-week IOP with multiple treatment tracks, including a general track.²⁰ The general track includes massed UP and additional standard services, including case management, wellness services, family services, and a single session effective behaviors group. Additional augmentation services are available when clinically indicated (eg, repetitive transcranial magnetic stimulation, transcranial direct current stimulation, psychoeducation, motivational interviewing, relapse prevention). In other words, this was an UP-IOP.²⁰

Thompson-Brenner et al described a successful implementation of massed UP applied in intensive treatment settings, such as residential and day-hospital programs, for eating disorders. Patients reported improvements in 3 UP targets: experiential avoidance, mindfulness, and anxiety.²¹ Watkins et al evaluated a 2-week IOP using CBT for comorbid substance use and mental health disorders, including prolonged exposure, UP, and relapse prevention for substance use disorders. Participants were post-9/11 veterans and activeduty personnel. Results indicated that UP reduced PTSD and depressive symptoms following treatment. Furthermore, the retention rate (91%) was higher than retention in outpatient treatment (39%-65%), supporting the IOP model as a strategy to reduce dropout.²²

Massed psychotherapy has been extended to IOP programs for PTSD treatment within the Veterans Health Administration (VHA). Yamokoski et al found that patients who completed an IOP that included massed CBT for PTSD had high retention, high satisfaction, and significant reduction in self-reported co-occurring depression symptoms. The authors also found that this model of care could be implemented and sustained within a VHA facility using minimal staffing resources.²³

The UP-IOP models described by Ragsdale et al and Watkins et al included massed UP as the primary evidence-based practice (EBP) with adjunctive groups (eg, wellness and educational groups and access to complementary interventions such as mindfulness and yoga); they found that adding these groups increased retention and patient- reported satisfaction (ie, UP-IOP).^20,22 The addition of wellness education alongside a primary EBP aligns with the VHA focus on whole health well-being and wellness. This includes understanding factors that motivate a patient toward health and well-being, providing health education, and offering access to complementary interventions such as mindfulness.²⁴

Dryden et al described the whole health transformation within VHA as a proactive approach to addressing both employee and patient wellness. Their research found that the whole health model promoted wellbeing in patients and staff and these improvements were sustained during the COVID-19 pandemic. Dryden et al also noted that virtual technologies facilitated continued whole health implementation.²⁵

The literature illustrates that (1) massed UP can be delivered with complementary education and wellness offerings that may increase retention and satisfaction by enriching treatment (eg, delivering UP-IOP); (2) whole health, including wellness education and complementary interventions (eg, mindfulness, motivational enhancement), promotes well-being in patients and clinicians; and (3) whole health education and complementary interventions can be delivered virtually.

Health Care Need

Veterans Affairs Pacific Islands Health Care System (VAPIHCS) provides medical services to veterans in the Hawaiian Islands, American Samoa, Guam, and Saipan spanning nearly 4000 miles across the Pacific Ocean. Prior to implementation of this program, veterans who received care at VAPIHCS had little to no access to UP in outpatient settings and no access to UP in residential settings. Access to UP depended on the presence of a therapist trained in UP within a given clinic and was geographically limited to the location of the UPtrained therapist. The limited outpatient access to UP was restricted to the traditional UP delivery model (eg, about 1 session/wk); thus, there was no access to accelerated UP for veterans served at VAPIHCS. In the fiscal year prior to implementation of the massed UP program, > 1000 VAPIHCS veterans had been diagnosed with obsessive-compulsive related disorder or anxiety. A massed-UP program with weekly rolling admissions would support access to UP for more veterans over 12 months, and the virtual treatment modality would reduce barriers for diverse and underserved veterans, making care more equitable and inclusive.

Successful implementation and sustainment of an EBP prompted the establishment of this UP program. In 2022, VAPIHCS launched the Intensive Virtual Evidence- Based Psychotherapy Team (iVET) for treatment of PTSD. This clinic and associated EBP project demonstrated that massed (≥3 individual sessions/wk) of prolonged exposure (PE) therapy, delivered virtually to a geographically diverse veteran population with PTSD, resulted in significant reductions in PTSD, depression, and anxiety symptoms and substance use risk factors, with very high retention rates. The iVET for PTSD program was feasible, acceptable, and effective, with veterans reporting significant improvement in quality of life and high satisfaction with their mental health services.¹⁵ Given the known benefits of transdiagnostic UP treatment (vs SDPs), the need for accelerated UP, and success with accelerated PE, our goal was to spread the EBP of massed (≥3 sessions/ wk) virtual psychotherapy to other presenting problems (eg, anxiety disorders with or without co-occurring unipolar depression) using transdiagnostic UP.

Program Description

The program implemented within outpatient mental health services at VAPIHCS was iVET for the treatment of anxiety with or without co-occurring depression. The program model consists of an accelerated course of UP and whole health education provided via VA Video Connect (VVC), the VA video telehealth platform. iVET is a 2- to 4-week program and consists of 3 parts: (1) massed individual UP for transdiagnostic treatment of anxiety and co-occurring depression, (2) group whole health and wellness classes, and (3) individual health coaching to address personal wellness goals. Programming is offered over 10-hour days to increase access across multiple time zones, especially to allow participation from Guam and Saipan.

When a patient is referred to iVET, the first contact is a video (or telephone) appointment with a registered nurse (RN) for a screening session. The screening session is designed to provide education about the program (including interventions, time commitment, and resources required for participation). Following education, the RN completes a safety screening, including screening for suicidal ideation and risk, as well as intimate partner violence risk. If urgent safety concerns are present, a licensed social worker or psychologist joins the screening to complete further risk assessment and address any safety concerns.

Following screening, patients are scheduled for a VVC telehealth intake with a licensed therapist (social worker or psychologist) to complete a diagnostic interview. Patients are sent a secure link to complete a measurement-based care (MBC) battery of self-report measures, including assessments of demographics, anxiety symptoms, depression symptoms, substance use, psychological flexibility, quality of life, and satisfaction with mental health care. The results of the diagnostic interview and self-report measures are discussed with the patient during the intake session to plan next steps and support shared decision-making. This initial VVC intake not only allows for fit assessment but also serves to troubleshoot technical difficulties with the virtual platforms.

Notably, there are minimal exclusion criteria for participation in iVET. These include active unmanaged psychosis or manic symptoms, recent suicidal crises (attempt within 8 weeks), active nonsuicidal self-injury (within 8 weeks), and moderate to severe cognitive impairment. Following intake, patients are scheduled to begin their course of care with iVET. Upon completion of intake, patients receive program materials for individual and group classes and are told they will receive email links for all VVC telehealth appointments. Patients are admitted to the iVET on a rolling basis, thereby increasing access compared with closed group and/or cohort models of care.

Patients receiving iVET attend 2 to 4 telehealth appointments daily and complete exercises between sessions. The primary iVET for Anxiety program EBP intervention is a massed or accelerated individual course of UP, which includes 8 primary components: assessment, goals and motivation, understanding emotions, mindful emotion awareness, cognitive flexibility, countering emotional behaviors, understanding and confronting physical sensations, and emotional exposures. UP is delivered in 4 to 8 individual sessions weekly (60-90 minutes each), allowing completion of the full UP protocol with fidelity in 2 to 4 weeks. In addition to primary EBP intervention, patients participate in 4 group sessions weekly (50 minutes each) of a whole health and wellness education class and have access to 1 individual health coaching session weekly (30- 60 minutes) to set wellness goals and receive coaching. During iVET, patients are invited to complete MBC batteries of self-report measures assessing anxiety symptoms, depression symptoms, substance use, psychological flexibility, quality of life, and satisfaction with mental health care at sessions 1, 5, 9, 13, and the final UP session. Following discharge from the iVET, patients are offered 1-, 3-, and 6-month individual postdischarge check-up sessions with a therapist, during which they are invited to complete MBC measures and review relapse prevention and maintenance of treatment gains. Likewise, patients are offered 1-, 3-, and 6-month individual postdischarge check-up sessions with an RN focused on maintaining wellness gains.

The iVET for Anxiety staff has 3 therapists (psychologists or social workers) and 1 RN. Additionally, the iVET for Anxiety is supported by a program manager and a program support assistant who support 2 programs total (the iVET for Anxiety plus another mental health program). The primary cost of the program is staff salary. Additional resources included computer equipment for staff and supplies (eg, printed materials for patients and office supplies). Due to the virtual environment of care, iVET staff telework and do not require physical space within VAPIHCS.

Outcomes

Veterans receiving iVET for Anxiety are invited to complete MBC multiple times, including pretreatment, during UP treatment (sessions 1, 5, 9, 13, and the final session), and posttreatment (1, 3, and 6 months). MBC measures include self-reported demographics; a 2-item measure of satisfaction with mental health services; the Acceptance and Action Questionnaire II,²⁶ the Brief Addiction Monitor-Intensive Outpatient Program, ²⁷ the Generalized Anxiety Disorder-7,²⁸ the Patient Health Questionnaire (PHQ-9),²⁹ and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form.³⁰

Forty-two veterans completed the iVET for Anxiety program, with a retention rate of 87.5% completing . 16 sessions of massed UP (Table 2). Veterans reported reduced anxiety (P < .001), depression (P < .001), and substance use risk (P < .001). Veterans experienced improved acceptance of emotional experiences (P < .001) and quality of life (P < .001), based on paired sample t tests comparing session 1 vs final session scores on the self-reported measures. Veterans also reported high satisfaction with mental health care in iVET for Anxiety.

Veterans experienced reduced thoughts of death or suicidal ideation (SI) based on responses to item 9 of PHQ-9. When SI was categorically analyzed (presence vs absence) using PHQ-9 item 9, there was an association observed between absence of SI and completion of a course of massed UP that does not appear to be due to chance, (X² [1, N = 42) = 3.94; P = .047). In addition, veterans who completed the program showed a significant decrease in SI severity measured continuously (range, 0-3) on PHQ-9 item 9 (P < .05) (Table 3).

Future Directions

The aim of this program is to see sustained patient outcomes as iVET continues to serve more veterans. Another line of inquiry is longer- term follow-up, given that long-term follow- up was not addressed in this project. We also hope that the accelerated model of care can be applied to treatment of other presenting concerns (eg, relationship difficulties, insomnia). Expansion of accelerated mental health treatment into other federal and nonfederal health care settings is another area worthy of future inquiry. Exploration of staff satisfaction and burnout related to providing accelerated UP is another important future direction. Relatedly, assessment of the staff burden to learn 1 transdiagnostic EBP vs learning multiple SDPs is another future direction. Likewise, exploration of institutional benefits of investment in transdiagnostic training, supervision, and consultation for UP vs multiple SDPs may be important. These areas could also result in insightful, beneficial evidence of the effectiveness of massed UP to add to the existing literature.

Conclusions

UP for transdiagnostic treatment of anxiety, depressive, and emotional disorders has demonstrated reduced suffering and improved functioning and is supported by multiple clinical practice guidelines.^1-4 Federal practitioners are positioned to improve access to this intervention, thereby reducing pain and improving lives. Indeed, it is crucial to envision a future state in which access to UP for a range of anxiety and depressive disorders is improved and broad, retention rates are dramatically improved, and clinicians providing UP do not experience the high burden and burnout associated with needing to learn and implement a variety of SDPs. Development of these programs, or similar tracks within existing programs, that provide massed or accelerated UP for transdiagnostic treatment of a range of anxiety and depressive disorders with virtual delivery options, is imperative to advance improved care for patients and clinicians.

Federal health care settings treating patients with anxiety and depression, such as those within the US Department of Defense, Indian Health Services, Bureau of Prisons, and VHA, are positioned to implement programs like iVET. Moreover, at the institutional level, investment in training and supervision in the transdiagnostic UP as opposed to multiple SDPs warrants consideration. We believe this model of care has great merit and foresee a future where all patients seeking treatment for anxiety and depression have the option to complete an accelerated or massed course of transdiagnostic care with UP if they so desire. Our experiences with iVET illustrate the feasibility, acceptability, and sustainability of such programs without requiring substantial staffing and financial resources.

We believe this model of care has great merit and foresee a future where all patients seeking treatment for anxiety and depression have the option to complete an accelerated or massed course of transdiagnostic care with UP if they so desire. Our experiences with iVET illustrate the feasibility, acceptability, and sustainability of such programs without requiring substantial staffing and financial resources.

Cognitive behavioral therapy (CBT) is supported as an effective treatment for depression by clinical practice guidelines from the US Department of Veterans Affairs (VA) and US Department of Defense.^1-3 Despite research supporting the use of evidence-based CBT for anxiety, mood, and emotional disorders, patient access to these interventions is limited.⁴ One barrier to CBT for anxiety, mood, and emotional disorders is the traditional use of single-disorder protocols (SDPs) to separately treat each disorder (eg, major depression, generalized anxiety disorder, panic disorder).

Use of SDPs places a high burden on clinicians, requiring them to learn and competently implement multiple different manualized interventions for each anxiety, mood, or emotional disorder encountered in practice.⁴ It is common for individuals who present with an anxiety, mood, or emotional disorder to experience co-occurring disorders.⁵ Traditional SDP-based CBT may require multiple SDPs to address co-occurring disorders, extending time in treatment and increasing training burden. There is evidence that even when an SDP is used, co-occurring difficulties may decrease in intensity.⁶ Thus, evidence-based CBT for 1 presenting concern may positively affect co-occurring difficulties that are not the primary treatment target.⁶

Unified Protocol (UP) is a transdiagnostic CBT intervention for anxiety and mood disorders. UP targets emotional experiences (eg, negative affect and emotional distress) that are present in multiple anxiety, depression, and emotional disorders. UP is organized into 8 modules and uses interventions present in other CBT SDPs, such as teaching objective assessment methods to clients, motivational enhancement and goal setting, emotion psychoeducation, mindful awareness, cognitive reframing, and exposure principles as mechanisms of change (Table 1).⁴ UP is an ideal intervention for addressing a number of anxiety, mood, and emotional disorders as well as addressing cooccurring disorders within the same course of treatment.

UP has been compared to SDPs; studies illustrate that UP is equivalent to SDPs at the end of treatment and at 6 months posttreatment.^4,7 Additionally, patients who received UP experienced symptom reduction for multiple co-occurring disorders.⁷ Furthermore, patients were less likely to drop out of UP when compared with SDPs.⁴

Studies have reported positive impacts on affective disorders with UP. A 2019 metaanalysis found significant reductions in depression and anxiety-related disorders.⁸ Additionally, UP has been shown to be effective when delivered in person and via telehealth.^9,10 UP has also been successfully used in veterans.¹¹ While traditional models of UP (1-2 sessions weekly) have a lower dropout rate than SDPs, UP and CBT dropout rates still leave room for improvement.^12-14 Specifically, rates of attrition from SDP CBT and transdiagnostic CBT protocols range from 9% to 35%, and dropout reduces the likelihood of attaining a full therapeutic dose of any course of CBT. Notably, accelerated delivery of CBT (ie, ≥3 sessions/wk) has been shown to reduce risk of dropout.^14,15

Veterans are at increased risk for suicide, and anxiety and mood disorders are associated with increased risk of suicide attempt and death.^16,17 Very few veterans who could benefit from high-quality CBT interventions, whether SDP or UP, are able to access them. Only 6.3% of veterans received ≥1 session of an evidence-based CBT SDP for posttraumatic stress disorder (PTSD) at 6 clinics evaluated in 2010.¹⁸

We identified 2 strategies to increase access to and completion of an evidence-based CBT course. First, the use of transdiagnostic UP instead of SDPs reduced burden on therapists and allowed them to address presenting and co-occurring disorders within the same course of care. Second, the use of an accelerated model of service delivery reduced dropout risk. Training clinicians to deliver UP is efficient and cost-effective, considering clinicians use core strategies that can be tailored and flexibly applied to a range of emotional difficulties. Thus, implementing UP may decrease barriers to receiving an optimal dose of an evidence-based CBT delivered with fidelity in a time- and cost-efficient manner.⁴ Two studies have found no evidence of differences in outcomes between UP and SDPs, suggesting that training and supervising clinicians in a single transdiagnostic UP intervention may prepare them to treat heterogeneous and co-occurring anxiety, mood, and emotional disorders with less burden than learning multiple SDPs.^7,19

Delivering UP in an accelerated or massed format (≥4 sessions/wk) instead of the traditional spaced model (1 session/wk) has empirical support but has not been widely implemented. This approach, sometimes referred to as a UP-intensive outpatient program (UP-IOP) or UP-intensive outpatient track (UP-IOT), has been shown to be feasible, acceptable, and effective, with increased completion rates compared with traditional UP delivery (1-2 sessions/wk).^20-22

Ragsdale et al describe a 2-week IOP with multiple treatment tracks, including a general track.²⁰ The general track includes massed UP and additional standard services, including case management, wellness services, family services, and a single session effective behaviors group. Additional augmentation services are available when clinically indicated (eg, repetitive transcranial magnetic stimulation, transcranial direct current stimulation, psychoeducation, motivational interviewing, relapse prevention). In other words, this was an UP-IOP.²⁰

Thompson-Brenner et al described a successful implementation of massed UP applied in intensive treatment settings, such as residential and day-hospital programs, for eating disorders. Patients reported improvements in 3 UP targets: experiential avoidance, mindfulness, and anxiety.²¹ Watkins et al evaluated a 2-week IOP using CBT for comorbid substance use and mental health disorders, including prolonged exposure, UP, and relapse prevention for substance use disorders. Participants were post-9/11 veterans and activeduty personnel. Results indicated that UP reduced PTSD and depressive symptoms following treatment. Furthermore, the retention rate (91%) was higher than retention in outpatient treatment (39%-65%), supporting the IOP model as a strategy to reduce dropout.²²

Massed psychotherapy has been extended to IOP programs for PTSD treatment within the Veterans Health Administration (VHA). Yamokoski et al found that patients who completed an IOP that included massed CBT for PTSD had high retention, high satisfaction, and significant reduction in self-reported co-occurring depression symptoms. The authors also found that this model of care could be implemented and sustained within a VHA facility using minimal staffing resources.²³

The UP-IOP models described by Ragsdale et al and Watkins et al included massed UP as the primary evidence-based practice (EBP) with adjunctive groups (eg, wellness and educational groups and access to complementary interventions such as mindfulness and yoga); they found that adding these groups increased retention and patient- reported satisfaction (ie, UP-IOP).^20,22 The addition of wellness education alongside a primary EBP aligns with the VHA focus on whole health well-being and wellness. This includes understanding factors that motivate a patient toward health and well-being, providing health education, and offering access to complementary interventions such as mindfulness.²⁴

Dryden et al described the whole health transformation within VHA as a proactive approach to addressing both employee and patient wellness. Their research found that the whole health model promoted wellbeing in patients and staff and these improvements were sustained during the COVID-19 pandemic. Dryden et al also noted that virtual technologies facilitated continued whole health implementation.²⁵

The literature illustrates that (1) massed UP can be delivered with complementary education and wellness offerings that may increase retention and satisfaction by enriching treatment (eg, delivering UP-IOP); (2) whole health, including wellness education and complementary interventions (eg, mindfulness, motivational enhancement), promotes well-being in patients and clinicians; and (3) whole health education and complementary interventions can be delivered virtually.

Health Care Need

Veterans Affairs Pacific Islands Health Care System (VAPIHCS) provides medical services to veterans in the Hawaiian Islands, American Samoa, Guam, and Saipan spanning nearly 4000 miles across the Pacific Ocean. Prior to implementation of this program, veterans who received care at VAPIHCS had little to no access to UP in outpatient settings and no access to UP in residential settings. Access to UP depended on the presence of a therapist trained in UP within a given clinic and was geographically limited to the location of the UPtrained therapist. The limited outpatient access to UP was restricted to the traditional UP delivery model (eg, about 1 session/wk); thus, there was no access to accelerated UP for veterans served at VAPIHCS. In the fiscal year prior to implementation of the massed UP program, > 1000 VAPIHCS veterans had been diagnosed with obsessive-compulsive related disorder or anxiety. A massed-UP program with weekly rolling admissions would support access to UP for more veterans over 12 months, and the virtual treatment modality would reduce barriers for diverse and underserved veterans, making care more equitable and inclusive.

Successful implementation and sustainment of an EBP prompted the establishment of this UP program. In 2022, VAPIHCS launched the Intensive Virtual Evidence- Based Psychotherapy Team (iVET) for treatment of PTSD. This clinic and associated EBP project demonstrated that massed (≥3 individual sessions/wk) of prolonged exposure (PE) therapy, delivered virtually to a geographically diverse veteran population with PTSD, resulted in significant reductions in PTSD, depression, and anxiety symptoms and substance use risk factors, with very high retention rates. The iVET for PTSD program was feasible, acceptable, and effective, with veterans reporting significant improvement in quality of life and high satisfaction with their mental health services.¹⁵ Given the known benefits of transdiagnostic UP treatment (vs SDPs), the need for accelerated UP, and success with accelerated PE, our goal was to spread the EBP of massed (≥3 sessions/ wk) virtual psychotherapy to other presenting problems (eg, anxiety disorders with or without co-occurring unipolar depression) using transdiagnostic UP.

Program Description

The program implemented within outpatient mental health services at VAPIHCS was iVET for the treatment of anxiety with or without co-occurring depression. The program model consists of an accelerated course of UP and whole health education provided via VA Video Connect (VVC), the VA video telehealth platform. iVET is a 2- to 4-week program and consists of 3 parts: (1) massed individual UP for transdiagnostic treatment of anxiety and co-occurring depression, (2) group whole health and wellness classes, and (3) individual health coaching to address personal wellness goals. Programming is offered over 10-hour days to increase access across multiple time zones, especially to allow participation from Guam and Saipan.

When a patient is referred to iVET, the first contact is a video (or telephone) appointment with a registered nurse (RN) for a screening session. The screening session is designed to provide education about the program (including interventions, time commitment, and resources required for participation). Following education, the RN completes a safety screening, including screening for suicidal ideation and risk, as well as intimate partner violence risk. If urgent safety concerns are present, a licensed social worker or psychologist joins the screening to complete further risk assessment and address any safety concerns.

Following screening, patients are scheduled for a VVC telehealth intake with a licensed therapist (social worker or psychologist) to complete a diagnostic interview. Patients are sent a secure link to complete a measurement-based care (MBC) battery of self-report measures, including assessments of demographics, anxiety symptoms, depression symptoms, substance use, psychological flexibility, quality of life, and satisfaction with mental health care. The results of the diagnostic interview and self-report measures are discussed with the patient during the intake session to plan next steps and support shared decision-making. This initial VVC intake not only allows for fit assessment but also serves to troubleshoot technical difficulties with the virtual platforms.

Notably, there are minimal exclusion criteria for participation in iVET. These include active unmanaged psychosis or manic symptoms, recent suicidal crises (attempt within 8 weeks), active nonsuicidal self-injury (within 8 weeks), and moderate to severe cognitive impairment. Following intake, patients are scheduled to begin their course of care with iVET. Upon completion of intake, patients receive program materials for individual and group classes and are told they will receive email links for all VVC telehealth appointments. Patients are admitted to the iVET on a rolling basis, thereby increasing access compared with closed group and/or cohort models of care.

Patients receiving iVET attend 2 to 4 telehealth appointments daily and complete exercises between sessions. The primary iVET for Anxiety program EBP intervention is a massed or accelerated individual course of UP, which includes 8 primary components: assessment, goals and motivation, understanding emotions, mindful emotion awareness, cognitive flexibility, countering emotional behaviors, understanding and confronting physical sensations, and emotional exposures. UP is delivered in 4 to 8 individual sessions weekly (60-90 minutes each), allowing completion of the full UP protocol with fidelity in 2 to 4 weeks. In addition to primary EBP intervention, patients participate in 4 group sessions weekly (50 minutes each) of a whole health and wellness education class and have access to 1 individual health coaching session weekly (30- 60 minutes) to set wellness goals and receive coaching. During iVET, patients are invited to complete MBC batteries of self-report measures assessing anxiety symptoms, depression symptoms, substance use, psychological flexibility, quality of life, and satisfaction with mental health care at sessions 1, 5, 9, 13, and the final UP session. Following discharge from the iVET, patients are offered 1-, 3-, and 6-month individual postdischarge check-up sessions with a therapist, during which they are invited to complete MBC measures and review relapse prevention and maintenance of treatment gains. Likewise, patients are offered 1-, 3-, and 6-month individual postdischarge check-up sessions with an RN focused on maintaining wellness gains.

The iVET for Anxiety staff has 3 therapists (psychologists or social workers) and 1 RN. Additionally, the iVET for Anxiety is supported by a program manager and a program support assistant who support 2 programs total (the iVET for Anxiety plus another mental health program). The primary cost of the program is staff salary. Additional resources included computer equipment for staff and supplies (eg, printed materials for patients and office supplies). Due to the virtual environment of care, iVET staff telework and do not require physical space within VAPIHCS.

Outcomes

Veterans receiving iVET for Anxiety are invited to complete MBC multiple times, including pretreatment, during UP treatment (sessions 1, 5, 9, 13, and the final session), and posttreatment (1, 3, and 6 months). MBC measures include self-reported demographics; a 2-item measure of satisfaction with mental health services; the Acceptance and Action Questionnaire II,²⁶ the Brief Addiction Monitor-Intensive Outpatient Program, ²⁷ the Generalized Anxiety Disorder-7,²⁸ the Patient Health Questionnaire (PHQ-9),²⁹ and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form.³⁰

Forty-two veterans completed the iVET for Anxiety program, with a retention rate of 87.5% completing . 16 sessions of massed UP (Table 2). Veterans reported reduced anxiety (P < .001), depression (P < .001), and substance use risk (P < .001). Veterans experienced improved acceptance of emotional experiences (P < .001) and quality of life (P < .001), based on paired sample t tests comparing session 1 vs final session scores on the self-reported measures. Veterans also reported high satisfaction with mental health care in iVET for Anxiety.

Veterans experienced reduced thoughts of death or suicidal ideation (SI) based on responses to item 9 of PHQ-9. When SI was categorically analyzed (presence vs absence) using PHQ-9 item 9, there was an association observed between absence of SI and completion of a course of massed UP that does not appear to be due to chance, (X² [1, N = 42) = 3.94; P = .047). In addition, veterans who completed the program showed a significant decrease in SI severity measured continuously (range, 0-3) on PHQ-9 item 9 (P < .05) (Table 3).

Future Directions

The aim of this program is to see sustained patient outcomes as iVET continues to serve more veterans. Another line of inquiry is longer- term follow-up, given that long-term follow- up was not addressed in this project. We also hope that the accelerated model of care can be applied to treatment of other presenting concerns (eg, relationship difficulties, insomnia). Expansion of accelerated mental health treatment into other federal and nonfederal health care settings is another area worthy of future inquiry. Exploration of staff satisfaction and burnout related to providing accelerated UP is another important future direction. Relatedly, assessment of the staff burden to learn 1 transdiagnostic EBP vs learning multiple SDPs is another future direction. Likewise, exploration of institutional benefits of investment in transdiagnostic training, supervision, and consultation for UP vs multiple SDPs may be important. These areas could also result in insightful, beneficial evidence of the effectiveness of massed UP to add to the existing literature.

Conclusions

UP for transdiagnostic treatment of anxiety, depressive, and emotional disorders has demonstrated reduced suffering and improved functioning and is supported by multiple clinical practice guidelines.^1-4 Federal practitioners are positioned to improve access to this intervention, thereby reducing pain and improving lives. Indeed, it is crucial to envision a future state in which access to UP for a range of anxiety and depressive disorders is improved and broad, retention rates are dramatically improved, and clinicians providing UP do not experience the high burden and burnout associated with needing to learn and implement a variety of SDPs. Development of these programs, or similar tracks within existing programs, that provide massed or accelerated UP for transdiagnostic treatment of a range of anxiety and depressive disorders with virtual delivery options, is imperative to advance improved care for patients and clinicians.

Federal health care settings treating patients with anxiety and depression, such as those within the US Department of Defense, Indian Health Services, Bureau of Prisons, and VHA, are positioned to implement programs like iVET. Moreover, at the institutional level, investment in training and supervision in the transdiagnostic UP as opposed to multiple SDPs warrants consideration. We believe this model of care has great merit and foresee a future where all patients seeking treatment for anxiety and depression have the option to complete an accelerated or massed course of transdiagnostic care with UP if they so desire. Our experiences with iVET illustrate the feasibility, acceptability, and sustainability of such programs without requiring substantial staffing and financial resources.

Evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD), such as prolonged exposure (PE), is supported by multiple clinical practice guidelines and is expected to be available to veterans served by the Veterans Health Administration (VHA).^1-5 However, traditional models of EBP delivery with 1 or 2 sessions weekly have high dropout rates.^6,7 Few veterans who could benefit from such EBPs receive them, and those who do have low completion rates.^8,9 Over a 15-year period, VHA records review of > 265,500 veterans with PTSD showed only 9.1% completed EBP treatment that included but was not limited to PE.¹⁰

One empirically supported solution that has yet to be widely implemented is delivering EBPs for PTSD in a massed or accelerated format of ≥ 3 sessions weekly.¹¹ While these massed models of EBP delivery for PTSD are promising, their implementation is limited in federal health care settings, such as the VHA.¹² PE therapy is a first-line treatment for PTSD that has been evaluated in numerous clinical trials since the early 1990s and in a wide range of trauma populations.^13,14 Massed PE is effective and PE has been found to be effective both in-person and via telehealth.^11,15,16

Another approach to accelerated PE is the inclusion of a massed PE course within a broader treatment context that includes augmentation of the massed PE with additional services, this is referred to as an intensive outpatient model (IOP).¹⁷ PE-IOP has also been shown to be feasible, acceptable, and effective with increased completion rates in comparison to the traditional (1 or 2 sessions weekly) model of PE.^12,16,18,19 Ragsdale et al describe a 2-week IOP with multiple treatment tracks, including a PTSD track. The PTSD treatment track includes massed PE and additional standard services including case management, wellness services, family services, and a single session effective behaviors group. Additional augmentation services are available when clinically indicated (eg, repetitive transcranial magnetic stimulation, transcranial direct current stimulation treatment, psychoeducation, motivational interviewing, and/or relapse prevention).¹⁷

Rauch et al studied the first 80 patients completing an IOP program that consisted of PE (5 sessions weekly) and complementary interventions (eg, mindfulness and yoga) and reported a 96% retention rate, significant reductions of self-reported PTSD symptoms, significant reduction in self-reported co-occurring depression symptoms, and significant increase in self-reported satisfaction with social functioning. ¹⁸ In another study, Sherril et al explored patient reactions to participation in massed PE (5 sessions weekly) and found that patients reported significantly more positive than negative reactions. Sherrill et al noted that according to patients, the benefits of massed PE included a structured format that limits avoidance and distraction. The resulting fast pace of progress enhanced motivation; however, drawbacks included short-term discomfort and time demands.¹⁹ Yamokoski et al explored the feasibility of massed PE in a larger study of PTSD treatment in an intensive outpatient track (IOT) in a VHA PTSD clinic with minimal staffing. The 48 patients who completed IOT PTSD treatment in 2 or 4 weeks (including 35 patients who received massed PE) had high retention rates (85%), reported high satisfaction, and had significantly reduced PTSD and depression symptoms.¹²

The massed IOT PE model implemented by Yamokoski et al included the primary EBP intervention of massed PE with adjunctive groups. The addition of these groups increased both retention and patient-reported satisfaction. The PE-IOP model implemented by Rauch et al and Sherrill et al also included wellness and educational groups, as well as access to complementary interventions such as mindfulness and yoga.^18,19 The addition of wellness education along with a primary EBP aligned with the VHA focus on whole health well-being and wellness. The whole health approach includes understanding the factors that motivate a patient toward health and well-being, provision of health education, and providing access to complementary interventions such as mindfulness.²⁰ Dryden et al describe the whole health transformation within VHA as a proactive approach to addressing employee and patient wellness and health. Their research found that the whole health model promoted well-being in patients and staff and was sustained even during the COVID-19 pandemic.²¹ Dryden et al also noted that use of virtual technologies facilitated and promoted continued whole health implementation. The literature illustrates that: (1) massed PE can be provided with complementary education and wellness offerings, and that such offerings may increase both retention and satisfaction by enriching the massed PE treatment (eg, delivering PE-IOP); (2) whole health including wellness education and complementary interventions (eg, mindfulness, motivational enhancement) promotes well-being in both patients and mental health professionals; and (3) whole health education and complementary interventions can be delivered virtually.

Health Care Need

Prior to the implementation of a massed EBP for PTSD program at US Department of Veterans Affairs (VA) Pacific Islands Health Care System (VAPIHCS), our setting included a traditional outpatient program for treatment of PTSD and a 12- bed residential program for treatment of PTSD for male-identified (self-identified and identified as male in the electronic medical record) veterans via a cohort model with an 8- or 9-week length of stay. Both programs were located on Oahu. Thus, veterans who received care at VAPIHCS had access to PE in both outpatient and residential settings and via in-person and telehealth modalities. However, their access to PE was limited to the traditional models of PE delivery (eg, 1 or 2 session per week) and very few veterans outside of the island of Oahu had accessed PE treatment for PTSD. Moreover, when looking at PE reach within VAPIHCS, in the fiscal year prior to the implementation of the massed EBP program, only 32 of the > 5000 eligible veterans with a PTSD diagnosis had received PE. VAPIHCS serves veterans in a catchment area across the Pacific Basin which includes 3 time zones: Hawaii Standard Time (HST), Chamorro Standard Time (ChST), and Samoa Standard Time (SST). ChST is 20 hours ahead of HST, making service delivery that is inclusive for patients in Guam and Saipan especially challenging when providing care from Hawaii or other US states or territories. Given all of this, implementation of a new program offering accelerated PE virtually to any veterans with PTSD within the VAPIHCS would increase access to and reduce barriers to receiving PE.

PROGRAM DESCRIPTION

The Intensive Virtual EBP Team (iVET) for PTSD consists of an accelerated course of PE therapy and whole health education provided via VA Video Connect (VVC). iVET is a 3-week program and includes 3 parts: (1) massed individual PE therapy for PTSD; (2) group whole health and wellness classes; and (3) individual health coaching to address personal wellness goals. Programming is offered over 10-hour days to increase access across multiple time zones, especially to allow for participation in Guam and Saipan.

When a patient is referred to the iVET, their first contact is a video (or telephone) appointment with a registered nurse (RN) for a screening session. The screening session is designed to educate the patient about the program, including interventions, time commitment, and resources required for participation. In addition, following the educational discussion, the RN completes screening for safety with the patient including suicidal ideation and risk, as well as intimate partner violence risk. If urgent safety concerns are present, a licensed social worker or psychologist will join the screening to complete further assessment of risk and to address any safety concerns. Following screening, patients are scheduled for a VVC intake with a licensed therapist (social worker or psychologist) to complete the Clinician-Administered PTSD Scale (CAPS-5) for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition), a clinical interview for PTSD assessment. Patients are also sent a secure link to complete a measurement-based care (MBC) battery of self-report measures including measures assessing demographics, PTSD symptoms, anxiety symptoms, depression symptoms, substance use, quality of life (QOL), and satisfaction with mental health care. The results of the CAPS-5 and self-report measures are discussed with the patient during the intake session when planning next steps and engaging in shared decision-making. This initial VVC intake not only allows for diagnostic goodness of fit but also provides the opportunity to troubleshoot any technical difficulties the patients might have with the virtual platforms.

There are minimal exclusion criteria for participation in iVET, which include active unmanaged psychosis or manic symptoms, recent suicidal crises (attempt within 8 weeks), active nonsuicidal self-injurious behaviors (within 8 weeks), and moderate-to-severe cognitive impairment. Following intake, patients are scheduled to begin their course of care with iVET. Upon completion of intake, patients are sent program materials for their individual and group classes, asked to obtain or request a recording device, and told they will receive email links for all VVC appointments. Patients are admitted to the iVET in a rolling admission fashion, thereby increasing access when compared to closed group and/or cohort models of care.

Patients receiving care in iVET attend 2 or 3 telehealth appointments daily with practice exercises daily between telehealth sessions. The primary EBP intervention in the iVET for PTSD program is a massed or accelerated course of PE, which includes 4 primary components: psychoeducation, in-vivo exposure, imaginal exposure, and breathing retraining. Specifically, PE is delivered in 4 90-minute individual sessions weekly allowing completion of the full PE protocol, to fidelity, in 3 weeks. In addition to receiving this primary intervention, patients also participate in four 50-minute group sessions per week of a whole health and wellness education class and have access to one 30- to 60-minute session weekly of individual health coaching should they wish to set wellness goals and receive coaching in support of attaining wellness goals. During iVET, patients are invited to complete MBC batteries of selfreport measures including measures assessing PTSD symptoms, anxiety symptoms, depression symptoms, substance use, QOL, and satisfaction with mental health care at sessions 1, 5, 9, and the final session of PE. Following discharge from the iVET, patients are offered 1-month, 3-month, and 6-month individual postdischarge check-up sessions with a therapist where they are invited to complete MBC measures and review relapse prevention and maintenance of treatment gains. Likewise, they are offered 1-month, 3-month, and 6-month postdischarge check-up sessions with an RN focused on maintaining wellness gains.

The iVET for PTSD staff includes 3 therapists (psychologists or social workers) and an RN. Additionally, the iVET for PTSD is supported by a program manager and a program support assistant. The primary cost of the program is salary for staff. Additional iVET for PTSD resources included computer equipment for staff and minimal supplies. Due to the virtual environment of care, iVET staff telework and do not require physical space within VAPIHCS.

OUTCOMES

All veterans receiving care in iVET for PTSD are invited to complete a MBC at multiple timepoints including pretreatment, during PE treatment, and posttreatment. The MBC measures included self-reported demographics, a 2-item measure of satisfaction with mental health services, the Brief Addiction Monitor-Intensive Outpatient Program questionnaire,²² the Generalized Anxiety Disorder-7 scale,^23, the Patient Health Questionnaire (PHQ-9),²⁴ the QOL Enjoyment and Satisfaction Questionnaire- Short Form,²⁵ and the PTSD Checklist for DSM-5 (PCL-5), both weekly and monthly versions. ^26,27

The retention rate has averaged 81% since the iVET for PTSD opened in 2022. To date, 132 veterans have completed the iVET for PTSD program, including a full course of massed PE (Table 1). Veterans experienced reduced PTSD (P < .005), depression (P < .005), anxiety (P < .005), and substance use risk (P < .005). Veterans experienced improved QOL (P < .005) and reported high satisfaction with mental health care in iVET for PTSD (Table 2). Veterans also experienced reduced thoughts of death or suicidal ideation (SI) based on PHQ-9 item 9 responses. When looking categorically at presence or absence of SI on PHQ-9 item 9, a significant relationship was found between the absence of suicidal ideation and completion of a course of massed PE: X² (1, N = 132) = 13.75, P < .001. In addition, veterans who completed the program showed a significant decrease in severity of SI as measured continuously (range, 0-3) on PHQ-9 item 9 (P < .005).

Another important aspect to consider when implementing massed models of EBP is the impact on employee well-being and job satisfaction. The impact of EBP on staff was assessed following the initial EBP project. To explore this further, all staff members in the iVET for PTSD were invited to engage in a small program evaluation. iVET staff were guided through a visualization meditation intended to recall a typical workday 1 month prior to starting their new position with iVET. After the visualization meditation, staff completed the Professional Quality of Life (ProQOL) scale, a 30-item, self-reported questionnaire for health care workers that evaluates compassion satisfaction, perceived support, burnout, secondary traumatic stress, and moral distress.²⁸ One week later, staff were asked to complete the ProQOL again to capture their state after the first 6 months into their tenure as iVET staff. iVET employees experienced significantly increased perceived support (P < .05), reduced burnout (P < .05), reduced secondary traumatic stress (P < .05), and reduced moral distress (P < .05). Team members also remarked on the rewarding nature of the work and care model.

Future Directions

Future research should aim to sustain these outcomes as the iVET program continues to serve more veterans. Another important line of inquiry is longer-term follow-up, as exploring if outcomes are maintained over time is an important question that has not been answered in this article. In addition, we hope to see the accelerated model of care applied to treatment of other presenting concerns in mental health treatment (eg, anxiety, depression, insomnia). Expansion of accelerated mental health treatment into other federal and non-federal health care settings is another worthy direction. Finally, while short term (6 months) assessment of staff satisfaction in iVET was promising, ongoing assessment staff satisfaction over a longer timeframe (1-5 years) is also important.

CONCLUSIONS

PE for PTSD has been demonstrated to be effective and improve functioning and is supported by multiple clinical practice guidelines.1-5 However, as federal practitioners, we must consider the reality that many of the individuals who could benefit are not engaging in PE and there is a high dropout rate for those that do. It is vital that we envision a future state where access to PE for PTSD is equitable and inclusive, retention rates are dramatically improved, and clinicians providing PE do not experience high rates of burnout.

We must continue exploring how we can better care for our patients and colleagues. We posit that the development of programs, or tracks within existing programs, that provide massed or accelerated PE for PTSD with virtual delivery options is an imperative step toward improved care. Federal health care settings treating trauma-exposed patients with PTSD, such as those within the US Department of Defense, Indian Health Services, Federal Bureau of Prisons, and VA, are well positioned to implement programs like iVET. We believe this model of care has great merit and foresee a future where all patients seeking PTSD treatment have the option to complete an accelerated or massed course of PE should they so desire. The experiences outlined in this article illustrate the feasibility, acceptability, and sustainability of such programs without requiring substantial staffing and financial resources.

Evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD), such as prolonged exposure (PE), is supported by multiple clinical practice guidelines and is expected to be available to veterans served by the Veterans Health Administration (VHA).^1-5 However, traditional models of EBP delivery with 1 or 2 sessions weekly have high dropout rates.^6,7 Few veterans who could benefit from such EBPs receive them, and those who do have low completion rates.^8,9 Over a 15-year period, VHA records review of > 265,500 veterans with PTSD showed only 9.1% completed EBP treatment that included but was not limited to PE.¹⁰

One empirically supported solution that has yet to be widely implemented is delivering EBPs for PTSD in a massed or accelerated format of ≥ 3 sessions weekly.¹¹ While these massed models of EBP delivery for PTSD are promising, their implementation is limited in federal health care settings, such as the VHA.¹² PE therapy is a first-line treatment for PTSD that has been evaluated in numerous clinical trials since the early 1990s and in a wide range of trauma populations.^13,14 Massed PE is effective and PE has been found to be effective both in-person and via telehealth.^11,15,16

Another approach to accelerated PE is the inclusion of a massed PE course within a broader treatment context that includes augmentation of the massed PE with additional services, this is referred to as an intensive outpatient model (IOP).¹⁷ PE-IOP has also been shown to be feasible, acceptable, and effective with increased completion rates in comparison to the traditional (1 or 2 sessions weekly) model of PE.^12,16,18,19 Ragsdale et al describe a 2-week IOP with multiple treatment tracks, including a PTSD track. The PTSD treatment track includes massed PE and additional standard services including case management, wellness services, family services, and a single session effective behaviors group. Additional augmentation services are available when clinically indicated (eg, repetitive transcranial magnetic stimulation, transcranial direct current stimulation treatment, psychoeducation, motivational interviewing, and/or relapse prevention).¹⁷

Rauch et al studied the first 80 patients completing an IOP program that consisted of PE (5 sessions weekly) and complementary interventions (eg, mindfulness and yoga) and reported a 96% retention rate, significant reductions of self-reported PTSD symptoms, significant reduction in self-reported co-occurring depression symptoms, and significant increase in self-reported satisfaction with social functioning. ¹⁸ In another study, Sherril et al explored patient reactions to participation in massed PE (5 sessions weekly) and found that patients reported significantly more positive than negative reactions. Sherrill et al noted that according to patients, the benefits of massed PE included a structured format that limits avoidance and distraction. The resulting fast pace of progress enhanced motivation; however, drawbacks included short-term discomfort and time demands.¹⁹ Yamokoski et al explored the feasibility of massed PE in a larger study of PTSD treatment in an intensive outpatient track (IOT) in a VHA PTSD clinic with minimal staffing. The 48 patients who completed IOT PTSD treatment in 2 or 4 weeks (including 35 patients who received massed PE) had high retention rates (85%), reported high satisfaction, and had significantly reduced PTSD and depression symptoms.¹²

The massed IOT PE model implemented by Yamokoski et al included the primary EBP intervention of massed PE with adjunctive groups. The addition of these groups increased both retention and patient-reported satisfaction. The PE-IOP model implemented by Rauch et al and Sherrill et al also included wellness and educational groups, as well as access to complementary interventions such as mindfulness and yoga.^18,19 The addition of wellness education along with a primary EBP aligned with the VHA focus on whole health well-being and wellness. The whole health approach includes understanding the factors that motivate a patient toward health and well-being, provision of health education, and providing access to complementary interventions such as mindfulness.²⁰ Dryden et al describe the whole health transformation within VHA as a proactive approach to addressing employee and patient wellness and health. Their research found that the whole health model promoted well-being in patients and staff and was sustained even during the COVID-19 pandemic.²¹ Dryden et al also noted that use of virtual technologies facilitated and promoted continued whole health implementation. The literature illustrates that: (1) massed PE can be provided with complementary education and wellness offerings, and that such offerings may increase both retention and satisfaction by enriching the massed PE treatment (eg, delivering PE-IOP); (2) whole health including wellness education and complementary interventions (eg, mindfulness, motivational enhancement) promotes well-being in both patients and mental health professionals; and (3) whole health education and complementary interventions can be delivered virtually.

Health Care Need

Prior to the implementation of a massed EBP for PTSD program at US Department of Veterans Affairs (VA) Pacific Islands Health Care System (VAPIHCS), our setting included a traditional outpatient program for treatment of PTSD and a 12- bed residential program for treatment of PTSD for male-identified (self-identified and identified as male in the electronic medical record) veterans via a cohort model with an 8- or 9-week length of stay. Both programs were located on Oahu. Thus, veterans who received care at VAPIHCS had access to PE in both outpatient and residential settings and via in-person and telehealth modalities. However, their access to PE was limited to the traditional models of PE delivery (eg, 1 or 2 session per week) and very few veterans outside of the island of Oahu had accessed PE treatment for PTSD. Moreover, when looking at PE reach within VAPIHCS, in the fiscal year prior to the implementation of the massed EBP program, only 32 of the > 5000 eligible veterans with a PTSD diagnosis had received PE. VAPIHCS serves veterans in a catchment area across the Pacific Basin which includes 3 time zones: Hawaii Standard Time (HST), Chamorro Standard Time (ChST), and Samoa Standard Time (SST). ChST is 20 hours ahead of HST, making service delivery that is inclusive for patients in Guam and Saipan especially challenging when providing care from Hawaii or other US states or territories. Given all of this, implementation of a new program offering accelerated PE virtually to any veterans with PTSD within the VAPIHCS would increase access to and reduce barriers to receiving PE.

PROGRAM DESCRIPTION

The Intensive Virtual EBP Team (iVET) for PTSD consists of an accelerated course of PE therapy and whole health education provided via VA Video Connect (VVC). iVET is a 3-week program and includes 3 parts: (1) massed individual PE therapy for PTSD; (2) group whole health and wellness classes; and (3) individual health coaching to address personal wellness goals. Programming is offered over 10-hour days to increase access across multiple time zones, especially to allow for participation in Guam and Saipan.

When a patient is referred to the iVET, their first contact is a video (or telephone) appointment with a registered nurse (RN) for a screening session. The screening session is designed to educate the patient about the program, including interventions, time commitment, and resources required for participation. In addition, following the educational discussion, the RN completes screening for safety with the patient including suicidal ideation and risk, as well as intimate partner violence risk. If urgent safety concerns are present, a licensed social worker or psychologist will join the screening to complete further assessment of risk and to address any safety concerns. Following screening, patients are scheduled for a VVC intake with a licensed therapist (social worker or psychologist) to complete the Clinician-Administered PTSD Scale (CAPS-5) for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition), a clinical interview for PTSD assessment. Patients are also sent a secure link to complete a measurement-based care (MBC) battery of self-report measures including measures assessing demographics, PTSD symptoms, anxiety symptoms, depression symptoms, substance use, quality of life (QOL), and satisfaction with mental health care. The results of the CAPS-5 and self-report measures are discussed with the patient during the intake session when planning next steps and engaging in shared decision-making. This initial VVC intake not only allows for diagnostic goodness of fit but also provides the opportunity to troubleshoot any technical difficulties the patients might have with the virtual platforms.

There are minimal exclusion criteria for participation in iVET, which include active unmanaged psychosis or manic symptoms, recent suicidal crises (attempt within 8 weeks), active nonsuicidal self-injurious behaviors (within 8 weeks), and moderate-to-severe cognitive impairment. Following intake, patients are scheduled to begin their course of care with iVET. Upon completion of intake, patients are sent program materials for their individual and group classes, asked to obtain or request a recording device, and told they will receive email links for all VVC appointments. Patients are admitted to the iVET in a rolling admission fashion, thereby increasing access when compared to closed group and/or cohort models of care.

Patients receiving care in iVET attend 2 or 3 telehealth appointments daily with practice exercises daily between telehealth sessions. The primary EBP intervention in the iVET for PTSD program is a massed or accelerated course of PE, which includes 4 primary components: psychoeducation, in-vivo exposure, imaginal exposure, and breathing retraining. Specifically, PE is delivered in 4 90-minute individual sessions weekly allowing completion of the full PE protocol, to fidelity, in 3 weeks. In addition to receiving this primary intervention, patients also participate in four 50-minute group sessions per week of a whole health and wellness education class and have access to one 30- to 60-minute session weekly of individual health coaching should they wish to set wellness goals and receive coaching in support of attaining wellness goals. During iVET, patients are invited to complete MBC batteries of selfreport measures including measures assessing PTSD symptoms, anxiety symptoms, depression symptoms, substance use, QOL, and satisfaction with mental health care at sessions 1, 5, 9, and the final session of PE. Following discharge from the iVET, patients are offered 1-month, 3-month, and 6-month individual postdischarge check-up sessions with a therapist where they are invited to complete MBC measures and review relapse prevention and maintenance of treatment gains. Likewise, they are offered 1-month, 3-month, and 6-month postdischarge check-up sessions with an RN focused on maintaining wellness gains.

The iVET for PTSD staff includes 3 therapists (psychologists or social workers) and an RN. Additionally, the iVET for PTSD is supported by a program manager and a program support assistant. The primary cost of the program is salary for staff. Additional iVET for PTSD resources included computer equipment for staff and minimal supplies. Due to the virtual environment of care, iVET staff telework and do not require physical space within VAPIHCS.

OUTCOMES

All veterans receiving care in iVET for PTSD are invited to complete a MBC at multiple timepoints including pretreatment, during PE treatment, and posttreatment. The MBC measures included self-reported demographics, a 2-item measure of satisfaction with mental health services, the Brief Addiction Monitor-Intensive Outpatient Program questionnaire,²² the Generalized Anxiety Disorder-7 scale,^23, the Patient Health Questionnaire (PHQ-9),²⁴ the QOL Enjoyment and Satisfaction Questionnaire- Short Form,²⁵ and the PTSD Checklist for DSM-5 (PCL-5), both weekly and monthly versions. ^26,27

The retention rate has averaged 81% since the iVET for PTSD opened in 2022. To date, 132 veterans have completed the iVET for PTSD program, including a full course of massed PE (Table 1). Veterans experienced reduced PTSD (P < .005), depression (P < .005), anxiety (P < .005), and substance use risk (P < .005). Veterans experienced improved QOL (P < .005) and reported high satisfaction with mental health care in iVET for PTSD (Table 2). Veterans also experienced reduced thoughts of death or suicidal ideation (SI) based on PHQ-9 item 9 responses. When looking categorically at presence or absence of SI on PHQ-9 item 9, a significant relationship was found between the absence of suicidal ideation and completion of a course of massed PE: X² (1, N = 132) = 13.75, P < .001. In addition, veterans who completed the program showed a significant decrease in severity of SI as measured continuously (range, 0-3) on PHQ-9 item 9 (P < .005).

Another important aspect to consider when implementing massed models of EBP is the impact on employee well-being and job satisfaction. The impact of EBP on staff was assessed following the initial EBP project. To explore this further, all staff members in the iVET for PTSD were invited to engage in a small program evaluation. iVET staff were guided through a visualization meditation intended to recall a typical workday 1 month prior to starting their new position with iVET. After the visualization meditation, staff completed the Professional Quality of Life (ProQOL) scale, a 30-item, self-reported questionnaire for health care workers that evaluates compassion satisfaction, perceived support, burnout, secondary traumatic stress, and moral distress.²⁸ One week later, staff were asked to complete the ProQOL again to capture their state after the first 6 months into their tenure as iVET staff. iVET employees experienced significantly increased perceived support (P < .05), reduced burnout (P < .05), reduced secondary traumatic stress (P < .05), and reduced moral distress (P < .05). Team members also remarked on the rewarding nature of the work and care model.

Future Directions

Future research should aim to sustain these outcomes as the iVET program continues to serve more veterans. Another important line of inquiry is longer-term follow-up, as exploring if outcomes are maintained over time is an important question that has not been answered in this article. In addition, we hope to see the accelerated model of care applied to treatment of other presenting concerns in mental health treatment (eg, anxiety, depression, insomnia). Expansion of accelerated mental health treatment into other federal and non-federal health care settings is another worthy direction. Finally, while short term (6 months) assessment of staff satisfaction in iVET was promising, ongoing assessment staff satisfaction over a longer timeframe (1-5 years) is also important.

CONCLUSIONS

PE for PTSD has been demonstrated to be effective and improve functioning and is supported by multiple clinical practice guidelines.1-5 However, as federal practitioners, we must consider the reality that many of the individuals who could benefit are not engaging in PE and there is a high dropout rate for those that do. It is vital that we envision a future state where access to PE for PTSD is equitable and inclusive, retention rates are dramatically improved, and clinicians providing PE do not experience high rates of burnout.

We must continue exploring how we can better care for our patients and colleagues. We posit that the development of programs, or tracks within existing programs, that provide massed or accelerated PE for PTSD with virtual delivery options is an imperative step toward improved care. Federal health care settings treating trauma-exposed patients with PTSD, such as those within the US Department of Defense, Indian Health Services, Federal Bureau of Prisons, and VA, are well positioned to implement programs like iVET. We believe this model of care has great merit and foresee a future where all patients seeking PTSD treatment have the option to complete an accelerated or massed course of PE should they so desire. The experiences outlined in this article illustrate the feasibility, acceptability, and sustainability of such programs without requiring substantial staffing and financial resources.

Evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD), such as prolonged exposure (PE), is supported by multiple clinical practice guidelines and is expected to be available to veterans served by the Veterans Health Administration (VHA).^1-5 However, traditional models of EBP delivery with 1 or 2 sessions weekly have high dropout rates.^6,7 Few veterans who could benefit from such EBPs receive them, and those who do have low completion rates.^8,9 Over a 15-year period, VHA records review of > 265,500 veterans with PTSD showed only 9.1% completed EBP treatment that included but was not limited to PE.¹⁰

One empirically supported solution that has yet to be widely implemented is delivering EBPs for PTSD in a massed or accelerated format of ≥ 3 sessions weekly.¹¹ While these massed models of EBP delivery for PTSD are promising, their implementation is limited in federal health care settings, such as the VHA.¹² PE therapy is a first-line treatment for PTSD that has been evaluated in numerous clinical trials since the early 1990s and in a wide range of trauma populations.^13,14 Massed PE is effective and PE has been found to be effective both in-person and via telehealth.^11,15,16

The 48 patients who completed IOT PTSD treatment in 2 or 4 weeks (including 35 patients who received massed PE) had high retention rates (85%), reported high satisfaction, and had significantly reduced PTSD and depression symptoms.¹²

The massed IOT PE model implemented by Yamokoski et al included the primary EBP intervention of massed PE with adjunctive groups. The addition of these groups increased both retention and patient-reported satisfaction. The PE-IOP model implemented by Rauch et al and Sherrill et al also included wellness and educational groups, as well as access to complementary interventions such as mindfulness and yoga.^18,19 The addition of wellness education along with a primary EBP aligned with the VHA focus on whole health well-being and wellness. The whole health approach includes understanding the factors that motivate a patient toward health and well-being, provision of health education, and providing access to complementary interventions such as mindfulness.²⁰ Dryden et al describe the whole health transformation within VHA as a proactive approach to addressing employee and patient wellness and health. Their research found that the whole health model promoted well-being in patients and staff and was sustained even during the COVID-19 pandemic.²¹ Dryden et al also noted that use of virtual technologies facilitated and promoted continued whole health implementation. The literature illustrates that: (1) massed PE can be provided with complementary education and wellness offerings, and that such offerings may increase both retention and satisfaction by enriching the massed PE treatment (eg, delivering PE-IOP); (2) whole health including wellness education and complementary interventions (eg, mindfulness, motivational enhancement) promotes well-being in both patients and mental health professionals; and (3) whole health education and complementary interventions can be delivered virtually.

The retention rate has averaged 81% since the iVET for PTSD opened in 2022. To date, 132 veterans have completed the iVET for PTSD program, including a full course of massed PE (Table 1). Veterans experienced reduced PTSD (P < .005), depression (P < .005), anxiety (P < .005), and substance use risk (P < .005).
