Since 1994, 3 days per week, trauma patients are transported by emergency medical services (EMS) to hospital A. The other 4 days they are transported to hospital B. Trauma registry data from 1994 to 2008 were analyzed. Cost data were also examined.
The joint system admitted 28,338 trauma patients. On each center's nontrauma days, trauma team activation was required infrequently. The 2 centers share costs; they perform joint outreach, educational training, and quality control. The joint trauma system has been sustained since 1994.
Two hospitals functioning as a single trauma center system is a viable model of care for injured patients in a moderate-sized city with mostly blunt trauma.
