The study team for the Trauma Survivors Outcomes and Support (TSOS) trial recently published their study protocol in Implementation Science. TSOS, an NIH Health Care Systems Research Collaboratory Demonstration Project, is an effectiveness-implementation hybrid trial designed to test the delivery of screening and intervention for PTSD and comorbidities across 24 U.S. level I trauma center sites. The study employs a stepped-wedge, cluster-randomized design in which sites are randomized sequentially to initiate the intervention. The study aims to determine if injured patients receiving a collaborative care intervention demonstrate significant reductions in PTSD symptoms when compared with control patients receiving usual care. The study will also evaluate whether intervention patients demonstrate significant reductions in depressive symptoms and associated suicidal ideation, alcohol use problems, and improvements in physical function.
