Improving function through primary care treatment of posttraumatic stress disorder study outcomes: A randomized controlled trial of prolonged exposure for primary care in veterans.

INTRODUCTION: Despite high cost and wide prevalence of posttraumatic stress disorder (PTSD) in veteran populations, and Veterans Health Administration (VA)-wide mental health provider training in evidence-based treatments for PTSD, most veterans with PTSD do not receive best practices interventions. This may be because virtually all evidence-based PTSD treatment is offered through specialty clinics, which require multiple steps and referrals to access. One solution is to offer PTSD treatment in VA primary care settings, which are often the first and only contact point for veterans. METHOD: The present study, Improving Function Through Primary Care Treatment of PTSD (IMPACT), used a randomized controlled design to compare an adaptation of prolonged exposure for PTSD to primary care (PE-PC) versus best practices Primary Care Mental Health Integration (PCMHI) clinic treatment as usual (TAU) in terms of both functioning and psychological symptoms in 120 veterans recruited between April 2019 and September 2021. RESULTS: Participants were mostly males (81.7%) with a mean age of 43.6 years (SD = 12.8), and more than half were non-White veterans (50.8%). Both conditions evinced significant improvement over baseline across functioning, PTSD, and depression measures, with no differences observed between groups. As observed in prior studies, PTSD symptoms continued to improve over time in both conditions, as measured by structured clinical interview. DISCUSSION: Both PE-PC and best-practices TAU are effective in improving function and reducing PTSD severity and depression severity. Although we did not observe differences between the two treatments, note that this study site and two PCMHI clinics employ primarily cognitive behavioral therapies (e.g., exposure and behavioral activation).

Treatment of posttraumatic stress disorder with prolonged exposure for primary care (PE-PC): Effectiveness and patient and therapist factors related to symptom change and retention.

Prolonged exposure (PE) is a first-line treatment for posttraumatic stress disorder (PTSD) available in specialty mental health. PE for primary care (PE-PC) is a brief version of PE adapted for primary care mental health integration, composed of four-eight, 30-min sessions. Using retrospective data of PE-PC training cases from 155 Veterans Health Administration (VHA) providers in 99 VHA clinics who participated in a 4- to 6-month PE-PC training and consultation program, we examined patients' PTSD and depression severity across sessions via mixed effects multilevel linear modeling. Additionally, hierarchical logistic regression analysis was conducted to assess predictors of treatment dropout. Among 737 veterans, medium-to-large reductions in PTSD (intent-to-treat, Cohen's d = 0.63; completers, Cohen's d = 0.79) and small-to-medium reductions in depression (intent-to-treat, Cohen's d = 0.40; completers, Cohen's d = 0.51) were observed. The modal number of PE-PC sessions was five (SD = 1.98). Providers previously trained in both PE and cognitive processing therapy (CPT) were more likely than providers who were not trained in either PE or CPT to have veterans complete PE-PC (OR = 1.54). Veterans with military sexual trauma were less likely to complete PE-PC than veterans with combat trauma (OR = 0.42). Asian American and Pacific Islander veterans were more likely than White veterans to complete treatment (OR = 2.93). Older veterans were more likely than younger veterans to complete treatment (OR = 1.11). (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Improving function through primary care treatment of PTSD: The IMPACT study protocol.

Despite the availability of effective psychological interventions for PTSD, access to and retention in these interventions remains problematic. Of note, the Veterans Health Administration (VHA) developed and implemented post-deployment health surveys that screen for PTSD in primary care (PC), but effective PC-based, psychological intervention treatment options have yet to be established. To address the literal physical gap between where the patients first present for care (i.e., primary care) and where they must go to receive first-line treatment for PTSD (i.e., specialty mental health), study investigators developed a 4-6 visit Prolonged Exposure for Primary Care (PE-PC) treatment that has shown efficacy in reduction of PTSD. To extend previous work to recovery-based mental health care, the Improving Function Through Primary Care Treatment of PTSD (IMPACT) study examined function as assessed by the World Health Organization Disability Assessment Schedule [WHODAS 2.0; (Axelsson, Lindsäter, Ljótsson, Andersson, & Hedman-Lagerlöf, 2017)]. Veterans presenting in VHA primary care mental health integration (PCMHI) clinics with PTSD or significant subsyndromal PTSD who met minimal inclusion and exclusion criteria were randomly assigned to PE-PC or treatment as usual (TAU). If proven effective in improving function, PE-PC would provide a new access point for high quality PTSD care and allow greater numbers of veterans to access effective PTSD treatment.
