IT Enhanced Peer Integrated Collaborative Care for US Trauma Care Systems

The investigators will use the Medical Outcomes Study Short Form healthy survey (MOS Short Form-12/36) physical components summary to assess physical function. The minimum and maximum scores are 0-100 with higher scores representing a better outcome.

Time frame: Baseline injury admission and 1-, 3-, 6-, 9- and 12-months post-injury follow-up

Population: For the physical functional status outcome, self-report data was collected from individual patients at each time point. Patient self-report interview follow-up completion varied at each time point across the intervention and control conditions. This accounts for samples less than 225 at the 1-, 3-, 6- , 9- and 12-month time points. Mixed-model regression analyses will be incorporated into the data analytic approach.

The severity of patient described post-injury concerns as rated by patients on a 1 through 5 scale; 1 being not at all concerning and 5 being extremely concerning. Higher scores are indicative of a worse outcome. The concern outcome can either be represented as a mean severity score or as a percentage of patients with one or more severe concerns.

Time frame: Baseline injury admission and 1-, 3-, 6-, 9- and 12-months post-injury follow-up

Population: For the severity of patient described post-injury concerns outcome, self-report data was collected from individual patients at each time point. Patient self-report interview follow-up completion varied at each time point across the intervention and control conditions. This accounts for samples less than 225 at the 1-, 3-, 6- , 9- and 12-month time points. Mixed-model regression analyses will be incorporated into the data analytic approach.

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.

Time frame: Baseline injury admission and 1-, 3-, 6-, 9- and 12-months post-injury follow-up

Population: For the posttraumatic stress symptom outcome, self-report data was collected from individual patients at each time point. Patient self-report interview follow-up completion varied at each time point across the intervention and control conditions. This accounts for samples less than 225 at the 1-, 3-, 6- , 9- and 12-month time points. Mixed-model regression analyses will be incorporated into the data analytic approach.

Number of emergency visits will be assessed using the Emergency Department Information Exchange (EDIE). More emergency visits are indicative of a worse outcome.

Time frame: Baseline injury admission to 12-months post-injury follow-up

Population: For the number of emergency department visits outcome, electronic health record data accrued on the entire intent-to-treat sample (N = 450) over the course of the 12-months after injury hospitalization. Mixed-model regression analyses will be incorporated into the data analytic approach.
