Injuries associated with snowmobiles, Alaska, 1993-1994

Objective. To characterize the nature and burden of snowmobile injuries in Alaska by examining injury deaths and hospitalizations associated with snowmobiles and comparing these with injury deaths and hospitalizations associated with on-road motor vehicles, Methods, The authors used vital statistics, medical examiner, Department of Public Safety, and Department of Transportation records to identify snowmobile injury deaths, and used vital statistics mortality files to identify on-road motor vehicle injury deaths. The Alaska Trauma Registry provided data on hospitalizations, The number of vehicles in use in 1993-1994 was estimated from snowmobile sales and on-road motor vehicle registrations, Results. For 1993-1994, injury death and hospitalization rates were greater for snowmobiles than for on-road motor vehicles. In northern Alaska, snowmobile injuries outnumbered on-road motor vehicle injuries, A total of 26 snowmobile injury deaths were reported; 7 decedents drowned after breaking through ice and 8 were ejected from vehicles. More than half (58%) of the snowmobile injury deaths involved a natural object such as a boulder, ravine, or river, Of the 17 decedents for whom blood alcohol concentrations were available, 11 (65%) had blood alcohol concentrations greater than or equal to 100 mg/dL. Conclusions. Natural obstacles and alcohol intoxication contribute to the high risk of injury death associated with snowmobile use. injury control strategies, including trail development and improvement, should be evaluated.
