Primary Aims and Hypotheses
The primary aim of the UH3 period is to conduct a pragmatic randomized effectiveness trial of a collaborative care intervention targeting PTSD and comorbid conditions after acute care injury hospitalization. The investigation aims to determine if injured patients receiving the collaborative care intervention demonstrate significant reductions in PTSD symptoms when compared to control patients receiving care as usual. The study also aims to determine if the intervention patients when compared to control patients will demonstrate significant reductions in depressive symptoms, suicidal ideation, and alcohol use problems, and improvements in physical function. The primary hypothesis is that the intervention group when compared to the control group will demonstrate significant reductions in PTSD symptoms over the course of the year after injury. Secondary hypotheses are that intervention patients when compared to control patients will demonstrate, significant reductions in depressive symptoms, significant reductions in alcohol use problems, and improved post-injury physical function.
A Priori Secondary Analyses
The study team hypothesizes that a subgroup of patients will have persistent PTSD symptoms that will not remit over the longitudinal course of the investigation, regardless of randomization to intervention or control group conditions. The study team also anticipates that readily identifiable baseline clinical, injury and demographic characteristics will be associated with persistent PTSD symptoms over time (e.g., higher PTSD symptom levels, greater pre-injury trauma exposure, intentional injury including firearm related injury mechanisms and other characteristics such as unemployment, as well as other baseline factors). Derived from previous randomized clinical trials, a cumulative burden index has been developed from these baseline characteristics and will be adapted for the current investigation. The study team proposes a series of secondary analyses that adjust for and stratify by baseline characteristics that put patients at risk for persistent symptoms. It is hypothesized that these secondary analyses will identify a subgroup of intervention patients who are not at risk for persistent symptoms and who will demonstrate clinically and statistically significant treatment responses when compared to patients with similar baseline characteristics in the control condition. The study team also hypothesizes that the treatment effects will be greatest at the 1-6 month post-injury time points that are temporally correlated with the period of active intervention.

---|---|
Experimental: Intervention
The intervention aims to prevent the development of chronic PTSD and depressive symptoms, alcohol use problems, and enduring physical disability in survivors of both traumatic brain injury(TBI) and non-TBI injuries. The intervention utilizes a computerized decision support tool to flexibly target these multiple conditions including and includes care management, motivational interviewing, cognitive behavioral therapy elements, psychotropic drugs, and psychotherapy elements.

- Change From Baseline PTSD Checklist- Civilian (PCL-C) Over the Course of the Year After Injury [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The investigators will use the PTSD Checklist - Civilian (PCL-C). The scoring of the scale ranges from a minimum of 17 to a maximum of 85, with higher scores indicating a worse outcome. The measure can also provide a rating of symptoms consistent with a diagnosis of PTSD.
- Change From Baseline Patient Health Questionnaire 9 Item Depression Scale Over the Course of the Year After Injury [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The investigators will use the Patient Health Questionnaire 9-item Depression Scale (PHQ-9). The scoring of the scale ranges from a minimum of 0 to a maximum of 27, with higher scores indicating a worse outcome.
- Change From Baseline Alcohol Use Disorders Identification Over the Course of the Year After Injury [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The investigators will use the Alcohol Use Disorders Identification Test (AUDIT) as a continuous measure. The 10-item scale score ranges from 0-40, with higher values indicating a worse outcome.
- Change From Baseline Short Form (SF)-12/36 Physical Function Over the Course of the Year After Injury [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The investigators used the Medical Outcomes Study Short Form healthy survey (MOS SF-12/36) physical components summary to assess physical function. The minimum and maximum scores are 0-100 with higher scores representing a better outcome.
- Number of Participants With Suicidal Ideation [ Time Frame: Baseline, 3-month, 6-month, 12-month ]Item 9 of the Patient Health Questionnaire 9-item (PHQ-9) scale assesses suicidal ideation. It is scored from 0 to 3, with a score of 1 or greater indicating a patient has suicidal ideation. Participants with a PHQ-9 item 9 score of greater than or equal to 1 are reported for this outcome.
- Number of Participants Endorsing a Single Item That Assesses Opioid Use [ Time Frame: Baseline, 3-month, 6-month, 12-month ]Single items that assess non-prescribed opioid use. Single item self-report dichotomized as none versus at least monthly use.
- Cognitive Impairment Scale [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The investigators will use the National Study on the Costs and Outcomes of Trauma (NSCOT) Cognitive Screen, a 4 - Item Traumatic Brain Injury / Post-concussive Symptom Screen. The scoring of the scale ranges from a minimum of 4 to a maximum of 20, with lower scores indicating a worse outcome.
- Brief Pain Inventory [ Time Frame: Baseline, 3-month, 6-month, 12-month ]A brief measure scored on a 0 to 10 scale to assess a patient's pain, with a higher score indicating more severe pain; a score of 0 indicates no pain and a score of 10 indicates very severe pain.
- SF-36 Quality of Life [ Time Frame: Baseline, 3-month, 6-month, 12-month ]The SF-36 assess quality of life domains that span emotional health, overall health status, and role function; a score of 100 indicates perfect health and a score of 0 indicates extremely poor health.
- TSOS Patient Satisfaction: Overall Health Care [ Time Frame: Baseline, 3-month, 6-month, 12-month ]Satisfaction with health care was rated on a scale of 1 to 5, with 1 indicating very dissatisfied and 5 indicating very satisfied.
- Number of Participants Endorsing a Single Item That Assesses Stimulant Use [ Time Frame: Baseline, 3-month, 6-month, 12-month ]Single items that assess non-prescribed stimulant use. Single item self-report dichotomized as none versus at least monthly use.
- Number of Participants Endorsing a Single Item That Assesses Marijuana Use [ Time Frame: Baseline, 3-month, 6-month, 12-month ]Single items that assess marijuana use. Single item self-report dichotomized as none versus at least monthly use.
- TSOS Patient Satisfaction: Mental Health Care [ Time Frame: Baseline, 3 Month, 6 Month, 12 Month ]Satisfaction with mental health care was rated on a scale of 1 to 5, with 1 indicating very dissatisfied and 5 indicating very satisfied.
