Crash characteristics of helmeted motorcyclists

The preliminary results of a prospective study of motorcycle crashes are reported. Motorcyclists were recruited from three major trauma centres in Sydney and through motorcycle organisations. The main sample criteria were that the cyclist crashed, and that they hit their head while wearing a helmet. Injury and non-injury cases were collected. Case sampling occurred over a period of 18 months. The response rate through hospitals was approximately 14 per cent for those meeting the selection criteria. All motorcyclists were interviewed and the helmets were examined. Characteristics such as environment (road type), vehicle (vehicle damage and interaction) and human factors were recorded. The location of helmet impacts and patterns of helmet damage were recorded. Injuries were documented and rated according to severity. The relationships between the crash characteristics, helmet use and injury are discussed.
