From 1982 through 1988, data on 127, 536 patients were submitted to the American College of Surgeons Major Trauma Outcome Study (MTOS) by 164 institutions, most North American Level I or II trauma centers. Motorcycle injuries had high mortality rate (9.0%) and average lengths of stay in hospital (13.1 days) and ICU (5.3 days) when compared with other causes of injury. Helmet use was recorded for less than 15% of patients.
