Improvised explosive devices (IEDs) have been one of the leading causes of death and injury among U.S. troops. Those who survive an IED blast or other injuries may be left with a traumatic brain injury (TBI) and attendant or co-occurring psychological symptoms. In response to the need for specialized services for these populations, the U.S. Department of Defense (DoD) established the National Intrepid Center of Excellence (NICoE) in Bethesda, Maryland, in 2010. The NICoE's success in fulfilling its mission is impacted by its relationships with home station providers, patients, and their families. The RAND Corporation was asked to evaluate these relationships and provide recommendations for strengthening the NICoE's efforts to communicate with these groups to improve patients' TBI care. Through surveys, site visits, and interviews with NICoE staff, home station providers, service members who have received care at the NICoE, and the families of these patients, RAND's evaluation examined the interactions between the NICoE and the providers responsible for referring patients and implementing treatment plans. --
