Background: It is estimated that 55 million adults will be 65 years and older in the USA by 2020. These older adults are at increased risk for injury and their recovery is multi-faceted. A collaborative care model may improve psychological and functional outcomes of the non-neurologically impaired older trauma patient and reduce health care costs. Methods: This is a randomized controlled trial of 430 patients aged 50 and older who have suffered a non-neurologic injury and are admitted to a level one trauma center in Indianapolis, IN, or Madison, WI. Participants will be assigned to either the Trauma Medical Home (TMH) intervention or usual care. The TMH intervention is a collaborative care model that includes validated protocols addressing the multi-faceted needs of this population, with the help of care coordination software and a mobile office concept. The primary outcome is self-reported physical recovery at 6- and 12-month follow-up. Secondary outcomes include self-reported psychological recovery, acute health care utilization, and cost-effectiveness of the intervention at 6 and 12 months. The TMH collaborative care model will be delivered by a registered nurse care coordinator. The assessments will be completed by trained blinded research assistants. Discussion: The proposed study will evaluate a collaborative care model to help maximize psychological and functional recovery for non-neurologically injured older patients at four level one trauma centers in the Midwest.
