BACKGROUND: Risk of deer motorcycle collisions (DMC) continues to increase in Midwestern and East Coast States and is a growing regional public health issue.
METHODS: We conducted a retrospective chart review of all motorcycle collisions involving animals over a 9-year period from October 1993 to October 2002. Data collected included Injury Severity Score (ISS), injury type, outcome, use of helmets/alcohol, time of year/day.
RESULTS: Fifty-five DMC were identified, 49 drivers, and 6 passengers. ISS for helmeted patients was 6.02 ± 4.6 and 17.6 ± 14.9 for non-helmeted patients. There were 7 human fatalities (all without helmets). Of the 55 patients, 16% of those injured were intoxicated, without helmets, and had average ISS higher than those non-intoxicated. Head, chest and orthopedic extremity trauma accounted for >70% of injuries seen within the entire population. Incidence peaked in June/July, and 55% of the collisions occurred between the hours of 1800 and 2200.
CONCLUSION: DMC are a significant public health issue in mid-western states. Education about helmet and alcohol use and safety on rural roads may be the best prevention. Continued research focusing on prevention is necessary.
