Patient Outcomes at Urban and Suburban Level I Versus Level II Trauma Centers.

Study Objective: Regionalized systems of trauma care and level verification are promulgated by the American College of Surgeons. Whether patient outcomes differ between the 2 highest verifications, Levels I and II, is unknown. In contrast to Level II centers, Level I centers are required to care for a minimum number of severely injured patients, have immediate availability of subspecialty services and equipment, and demonstrate research, substance abuse screening, and injury prevention.
