Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed project will examine a promising brief therapy for posttraumatic stress Disorder (PTSD) for use in Veterans Health Administration (VHA) Primary Care and its impact on functional outcomes. This intervention will provide an alternative point of access to effective PTSD treatment and improved function that does not require referral to specialty mental health and accomplishes improved function in a short-term, brief protocol. Many Veterans prefer to receive mental health care, including PTSD service in primary care. The current protocol would allow them to access effective therapy options in addition to the medication management that is currently the standard of care for PTSD in primary care. In addition, this brief protocol may reduce the number of specialty mental health referrals as many Veterans may not require additional PTSD specific treatment after completion. Thus, if effective, this protocol will greatly increase Veteran treatment choice and improve functional outcomes and access while also increasing efficiency of allocation of specialty PTSD services.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Posttraumatic stress disorder (PTSD) is a debilitating and costly mental health issue (Greenberg, Sisitsky et al. 1999, Hoge, Terhakopian et al. 2007). PTSD has an estimated two-year cost of $4.0 to $6.2 billion US dollars for mental health issues from the current conflicts in Iraq and Afghanistan and further estimated that providing evidence-based treatments for PTSD and depression could save an estimated $86.2 million (Tanielian, et al. 2008). Even modest reductions in PTSD severity have been related to increased probability of positive function outcomes (Smith, et al. 2005). Prolonged Exposure (PE) therapy (Foa, et al. 2000, Foa, et al. 2005, Schnurr, et al. 2007) is an effective, first-line treatment for PTSD (IOM 2007, VHA/Department of Defense (DOD) 2010). While highly effective, PE is provided in specialty mental health settings typically in 8 to 15, weekly 90 minute individual sessions. Veterans with PTSD are often reluctant to seek care in specialty mental health, and, as a result, many are treated solely in primary care and do not have access to this effective intervention (Possemato, et al. 2011). While the DOD and Veterans Administration (VA) have actively integrated behavioral health providers into their primary care clinics (Maguen, et al. 2010, Seal, et al. 2011), current behavioral interventions for PTSD in primary care are often inconsistent with clinical practice guidelines and/or not effective (Possemato, et al. 2011). Since functional outcomes are critical, the investigators intend to extend beyond assessing the impact of PE-PC on clinical outcomes to function. Thus, there is a clear and urgent need to further develop, validate, and disseminate evidence-based psychotherapeutic treatments for PTSD in integrated VHA Primary Care Mental Health Integration (PC-MHI) with a focus on functional outcomes. To fill this need and gap in care the study investigators developed a Brief Prolonged Exposure for Primary Care (PE-PC) treatment protocol with 4, 30-minute sessions for use in a stepped care model. A pilot study in military treatment facilities found PE-PC resulted in reductions in PTSD that were maintained at 6- and 12-month follow-up (Cigrang, et al, 2015). Preliminary results from a randomized controlled trial (RCT; PI: Cigrang; Co-Investigator: Rauch) of PE-PC compared to minimal attention control (MAC, including continuation of any PC initiated treatment) found a significantly larger reduction in PTSD severity (measured by PCL) in PE-PC than MAC (between group d = .78, p = .01). The strength of these initial findings is limited by lack of functional outcomes and examination of impact in VHA. While Service Members and Veterans have many similarities, potential differences in motivation for treatment and other factors may influence the efficacy of the protocol especially when examining changes in function. The proposed study will randomize 120 Veterans at Ralph H. Johnson Veterans Administration Medical Center (VAMC) presenting in primary care with PTSD who meet minimal inclusion/exclusion criteria to 6 weeks of PE-PC or PC-MHI-treatment as usual (TAU). Recruitment will occur over 36 months. All Veterans will complete a baseline assessment prior to randomization and post-treatment follow-up assessments at Weeks 6, 12, and 24 post-randomization. Primary outcome will be function assessed as self-reported role function in several domains. In addition, the investigators will examine symptoms severity and effectiveness, acceptability, and utilization associated with PE-PC or PCMHI-TAU in the 6 months prior to randomization and 6 months following treatment completion. PE-PC may allow access to effective treatment and efficient allocation of PTSD specialty treatment resources in the VHA. This topic is of key relevance to Veteran mental health care and can provide a new access point for high quality PTSD care to improve function allowing many more Veterans to experience improvement.
