Abstract
Background: Each year in the USA, 1.5–2.5 million Americans are so severely injured that they require inpatient
hospitalization. Multiple conditions including posttraumatic stress disorder (PTSD), alcohol and drug use problems,
depression, and chronic medical conditions are endemic among physical trauma survivors with and without
traumatic brain injuries.
Methods/design: The trauma survivors outcomes and support (TSOS) effectiveness-implementation hybrid
trial is designed to test the delivery of high-quality screening and intervention for PTSD and comorbidities
across 24 US level I trauma center sites. The pragmatic trial aims to recruit 960 patients. The TSOS
investigation employs a stepped wedge cluster randomized design in which sites are randomized
sequentially to initiate the intervention. Patients identified by a 10-domain electronic health record screen
as high risk for PTSD are formally assessed with the PTSD Checklist for study entry. Patients randomized to the
intervention condition will receive stepped collaborative care, while patients randomized to the control condition will
receive enhanced usual care. The intervention training begins with a 1-day on-site workshop in the collaborative care
intervention core elements that include care management, medication, cognitive behavioral therapy, and motivationalinterviewing elements targeting PTSD and comorbidity. The training is followed by site supervision from the study team.
The investigation aims to determine if intervention patients demonstrate significant reductions in PTSD and depressive
symptoms, suicidal ideation, alcohol consumption, and improvements in physical function when compared to control
patients. The study uses implementation science conceptual frameworks to evaluate the uptake of the intervention
model. At the completion of the pragmatic trial, results will be presented at an American College of Surgeons’ policy
summit. Twenty-four representative US level I trauma centers have been selected for the study, and the protocol is being
rolled out nationally.

Discussion: The TSOS pragmatic trial simultaneously aims to establish the effectiveness of the collaborative care
intervention targeting PTSD and comorbidity while also addressing sustainable implementation through American
College of Surgeons’ regulatory policy. The TSOS effectiveness-implementation hybrid design highlights the importance
of partnerships with professional societies that can provide regulatory mandates targeting enhanced health care system
sustainability of pragmatic trial results.

Background
The overarching goal of the trauma survivors outcomes
and support (TSOS) effectiveness-implementation hybrid clinical trial is to develop and implement a large
scale, cluster randomized pragmatic demonstration project that directly informs national trauma care system
policy targeting injured patients with presentations of
posttraumatic stress disorder (PTSD) and related comorbidity. Physical injury occurs frequently in the USA and
constitutes both a substantial source of individual suffering and a significant public health burden. Each year in
the USA, over 30 million individuals present to acute
care medical trauma center and emergency department
settings for the treatment of traumatic physical injury
[1–5]. Injured trauma survivors present to acute care
medical settings after both intentional (e.g., gunshots,
stabbings, physical assaults) and unintentional (natural
disasters, motor vehicle crashes) injury events [6]. Annually, 1.5–2.5 million Americans are so severely injured
that they require inpatient hospitalization [1–5]. Estimates suggest that approximately 1.5 million American
youth and adults experience traumatic brain injury (TBI)
annually [7, 8]. Physical injury with and without TBI
constitutes a major public health problem for both civilian and veteran patient populations [9, 10]. Globally,
traumatic injury accounts for approximately 16 % of the
world’s burden of disease [11–13].
Multiple chronic conditions appear to be endemic
among physical trauma survivors treated in US trauma
care systems [14–16]. Recent commentary has explicated
chronic conditions as conditions that last 1 year or more
and require ongoing medical attention and/or limit activities of daily living [17–19]. Highly prevalent comorbidities
include enduring PTSD, depression, and associated suicidal
ideation, alcohol, and drug use problems, TBI, and chronic
medical conditions such as hypertension, coronary artery
disease, diabetes, and pulmonary disease [14, 20, 21].
Evidence-based, collaborative care intervention models
for PTSD and related comorbidities exist [16, 22–25]. Collaborative care treatment models however, have yet to be
broadly implemented throughout US trauma care systems;
prior investigation by members of the interdisciplinary
study team suggest that less than 10 % of US trauma centers routinely provide post-injury screening or integrated
care management treatment targeting the cluster of
PTSD and related comorbidities [26]. The enduring
challenges presented by the chronic disease cluster of
PTSD and comorbidities aft (...truncated)
