    ObjectiveThe objective of the study was to develop and implement a stepped collaborative care intervention targeting posttraumatic stress disorder (PTSD) and related comorbidities to enhance the population impact of early trauma-focused interventions.MethodWe describe the design and implementation of the Trauma Survivors Outcomes and Support study. An interdisciplinary treatment development team was composed of trauma surgical, clinical psychiatric and mental health services "change agents" who spanned the boundaries between frontline trauma center clinical care and acute care policy. Mixed method clinical epidemiologic and clinical ethnographic studies informed the development of PTSD screening and intervention procedures.ResultsTwo hundred seven acutely injured trauma survivors with high early PTSD symptom levels were randomized into the study. The stepped collaborative care model integrated care management (i.e., posttraumatic concern elicitation and amelioration, motivational interviewing and behavioral activation) with cognitive behavioral therapy and pharmacotherapy targeting PTSD. The model was feasibly implemented by frontline acute care masters in social work and nurse practioner providers.ConclusionsStepped care protocols targeting PTSD may enhance the population impact of early interventions developed for survivors of individual and mass trauma by extending the reach of collaborative care interventions to acute care medical settings and other nonspecialty posttraumatic contexts.Copyright © 2011 Elsevier Inc.
