Trial name or title	Enhancing the population impact of collaborative care interventions: mixed method development and implementation of stepped care targeting post‐traumatic stress disorder and related comorbidities after acute trauma
Methods	Randomised controlled trial
Participants	English‐speaking women and men 18 years and older who presented to Harborview with injuries so severe that they required inpatient surgical admissions. Patients who had suffered head, spinal cord or other severe injuries that prevented participation in the inpatient ward interview were excluded from the study. Patients who required immediate intervention (i.e. self‐inflicted injury, active psychosis) were referred for evaluation to the inpatient psychiatric consult service. Patients who were currently incarcerated or who had recent histories of severe violence were also excluded. Patients living at great distances from the trauma centre (i.e. N50–100 miles) were excluded as the investigative team anticipated difficulty in long distance care co‐ordination activities
Interventions	Intervention: Stepped collaborative care intervention. The intervention included trauma‐focused care management, and an initial choice of starting with either evidence‐based pharmacotherapy or CBT targeting PTSD and related comorbidities Control: Usual care
Outcomes	PTSD symptom reduction (PTSD checklist (PCL) and the Clinician‐Administered PTSD Scale (CAPS)). Secondary outcomes include ratings of substance use and functional outcomes
Starting date	2011
