Evidence-based therapies for posttraumatic stress disorder are underutilized and at times unavailable in specialty settings. We reviewed the literature on interventions to treat PTSD within primary care to make recommendations on their effectiveness as treatment modalities or ways to improve engagement in specialty care. We searched PubMed, PsychInfo, CINHAL, and Cochrane Reviews databases using search terms related to PTSD and primary care. We excluded clinical guidelines and studies of screening only or subthreshold PTSD. 524 articles were identified. Twenty-one papers on 15 interventions met review criteria. Seven interventions focus on individual therapies studied via small feasibility studies to prepare for full-scale intervention research. Eight describe treatment programs in primary care based on collaborative care that included medication management, tracking outcomes, referral services, and for some psychotherapy (versus psychotherapy referral). Ten interventions were feasibility studies which precludes meaningful comparison of effect sizes. Of the four RCTs of treatment programs, only two including some psychotherapy found improvements in PTSD symptoms. More research is needed to adapt treatment for PTSD to primary care. Collaborative care may be a promising framework for improving the reach of PTSD treatments when psychotherapy is offered within the collaborative care team.
