Demographic and medical characteristics of adult head injuries in a Canadian setting.

This study provides demographic and medical information about patients admitted with head injuries to Sunnybrook Medical Centre, Toronto, Ont., in 1978 and in 1982. Data are presented about patient age and sex, type and cause of accident, length of stay, extracranial complications, severity of head injury, frequency of use of various neurodiagnostic techniques and type of discharge placement. The costs of hospitalization for such patients, both in the Sunnybrook Medical Centre and for Canada as a whole, are estimated.
