ENGLISH SUMMARY
Introduction: Bicycling has become increasingly popular in Iceland.
Official registration of bicycle accidents is based on police reports. As
minor accidents are often not reported to the police, these accidents
may be underreported in police records. The aim of this study was
to examine the epidemiology of bicycle related accidents in patients
seeking medical assistance at the Emergency Department (ED) at Land-
spitali-University Hospital, Reykjavik (LUH), Iceland.
Materials and methods: This retrospective cohort study was conduc-
ted at the ED at LUH, Iceland from January 2005 to December 2010. All
medical files were reviewed and sex, age, year and month of accident/
injury, helmet wearing, ICD-10 diagnosis, severity of injury according
to the Abbreviated Injury Scale (AIS) and the Injury Severity Score (ISS)
recorded. The rate of hospital admission was examined with length of
stay, Intensive Care Unit admission, use of medical imaging and opera-
tive treatment.
Results: A total of 3472 patients presented to the ED with bicycle
related accidents , 68.3% men and 31.7% female. The average age of
patients was 22,6 years (1-95 years). Most are injured during recrea-
tional activities (72.4%) and in residence areas (45,7%). Most injuries
occurred during May-September (71.4%). Data on counterparty was
missing in 74.9% of cases. The cause of accident was in 44.0% a low
fall or jump. The upper extremity was injured in 47.1% cases. A majority
of the patients (65.6%) had a mild injury (ISS≤3points) and 29.3% had
a moderate injury (4-8 points). No fatalities were found during the study
period. Use of helmets was only recorded in 14.2% of cases. In total 124
patients were admitted during the period where the mean time of admis-
sion was 5 days.
Conclusion: The incidence of bicycle injuries increased during the study
period but appears to have increased less than the number of bicyclists.
Injuries are more frequent among males and the majority are of a young
age. The accidents usually occur during the spring and summer. Most
injuries are minor but 3.6% required admission.
