A review of serious injuries and deaths from bicycle accidents in Sweden from 1987 to 1994.
BACKGROUND
Injured cyclists are often seen in emergency departments. The aims of this study were to determine the long-term incidence of injuries, age and gender distributions, mortality rates, and geographic differences among all patients admitted to hospitals because of bicycle accidents in Sweden.


METHODS
Between 1987 and 1994, 34,606 persons (39,183 admissions) were injured in bicycle accidents in Sweden (19,978 men and 14,628 women).


RESULTS
The annual frequency of hospital admissions ranged from 4,585 to 5,212. Fifty-seven patients were admitted with bicycle-related injuries per 100,000 population each year. Children between 5 and 14 years of age, especially boys, and men older than 70 were more commonly involved. Injuries to the head and brain were very frequent (46%). The survival rate was poorest in persons of older age, male gender, and cyclists involved in collisions with motor vehicles.


CONCLUSIONS
About 4,900 cyclists have been hospitalized each year after bicycle accidents in Sweden. Young children were affected very often, with injuries of the brain and various types of fractures of the extremities being common. Significant factors for a poor survival outcome included old age, male gender, and collisions with motor vehicles.
