Abstract
Background The purpose of this study was to identify the impact of motorcycle helmet use on patient outcomes and cost of hospitalization, in a state with a mandatory helmet law. Methods Patients admitted after motorcycle crashes from July 1996 to October 2000 were reviewed, including demographics, Injury Severity Score, length of stay, injuries, outcome, helmet use, hospital cost data, and insurance information. Statistical analysis was performed comparing helmeted to unhelmeted patients using analysis of variance, Student’s t test, and regression analysis. Results We admitted 216 patients: 174 wore helmets and 42 did not. Injury Severity Score correlated with both length of stay and cost of hospitalization. Mortality was not significantly different in either group. Failure to wear a helmet significantly increased incidence of head injuries (Student’s t test, p < 0.02), but not other injuries. Helmet use decreased mean cost of hospitalization by more than $6,000 per patient. Conclusion Failure to wear a helmet adds to the financial burden created by motorcycle-related injuries. Therefore, individuals who do not wear helmets should pay higher insurance premiums.
