Posttraumatic stress disorder (PTSD) is a common problem in primary care.
Although effective treatments are available, little is known about whether such
treatments are effective within the context of Federally Qualified Health
Centers (FQHCs) that serve as national “safety nets” for
providing primary care for low income and underinsured patients. The Violence
and Stress Assessment (ViStA) study is the first randomized controlled trial
(RCT) to test the impact of a care management intervention for treating PTSD in
FQHCs. To develop a PTSD management intervention appropriate for lower resource
FQHCs and the predominantly Latino patients they serve, formative work was
conducted through a collaborative effort between researchers and an FQHC
practice-based research network. This article describes how FQHC stakeholders
were convened to review, assess, and prioritize evidence-based strategies for
addressing patient, clinician, and system-level barriers to care. This
multi-component care management intervention incorporates diagnosis with
feedback, patient education and activation; navigation and linkage to community
resources; clinician education and medication guidance; and structured
cross-disciplinary communication and continuity of care, all facilitated by care
managers with FQHC experience. We also describe the evaluation design of this
five-year RCT and the characteristics of the 404 English or Spanish speaking
patients enrolled in the study and randomized to either the intervention or to
usual care. Patients are assessed at baseline, six months, and 12 months to
examine intervention effectiveness on PTSD, other mental health symptoms,
health-related quality-of-life, health care service use; and perceived barriers
to care and satisfaction with care.
