Abstract


OBJECTIVE
This study aimed to identify the characteristics of bicycle driver accidents, and investigate the factors related to the admission.
METHODS
Adult patients (≥20 years old), who visited the emergency department (ED) after a bicycle driver accident registered in the Korean ED-based Injury In-Depth Surveillance (2011-2016) database, were included. The demographic characteristics, accident-related factors, and patients'disposition after the ED treatment were collected. All included cases were categorized into two groups according to the disposition: discharge versus admission. The characteristics of the two groups were compared, and the factors associated with admission were investigated.
RESULTS
Among 25,070 ED visits, admissions were required in 5,963 patients (23.8%). The most frequent age group was the twenties (22.0%), and there were more males (74.7%) than females. Accidents occurred most in the summer (34.4%), and non-bicycle roads (73.5%) were the most common places. The most frequently injured body part was the head/neck (43.0%), followed by the upper extremities (21.5%). The odds for admission were lower in females than males (odds ratio [OR], 0.87; 95% confidence interval [CI], 0.78-0.96). The odds for admission were higher in the age group over 40 years than in their twenties. Non-bicycle roads had higher odds for admission than bicycle roads (OR, 1.60; 95% CI, 1.40-1.83). Torso (OR, 2.17; 95% CI, 1.92-2.47), upper extremities (OR, 1.20; 95% CI, 1.07-1.35), and lower extremities (OR, 1.48; 95% CI, 1.31-1.66) had higher odds for admission than the head/neck.
CONCLUSION
Male sex, old age group, accidents on non-bicycle roads, and torso/extremities injuries were associated with the admission in bicycle driver accidents.
