Surgeons have long recognized that a proportion of hospitalized trauma patients present with a history of a previous admission for trauma, termed by the authors as "trauma recidivism." The incidence of trauma recidivism was addressed by a review of 150 consecutive admissions to a level I Trauma Center. This study identifies this subset of trauma patients, establishes their magnitude, and analyzes mechanisms of injury and hospital courses. The implications for those who care for trauma patients is discussed.
