title: Cyclists injured while sharing the road with motor vehicles.
abstract: OBJECTIVE
  To provide national estimates of non-fatal cyclist injuries treated in US hospital emergency departments (EDs) resulting from an encounter with a motor vehicle (MV) on the road.
  
  
  METHODS
  Non-fatal injury data for 2001-4 from the National Electronic Injury Surveillance System All Injury Program were analyzed.
  
  
  RESULTS
  An estimated 62,267 persons (21.5 per 100,000 population; 95% CI 14.3 to 28.7) were treated annually in US hospital EDs for unintentional non-fatal cyclist injuries involving an MV on the road. Among these cases, children aged 10-14 years (65.8 per 100,000) and males (35.3 per 100,000) had the highest injury rates. Many injuries involved the extremities (41.9%). The head was the primary body part affected for 38.6% of hospitalized/transferred patients, of which about 84.7% had a principal diagnosis of a concussion or internal head injury.
  
  
  CONCLUSIONS
  Effective road environmental interventions (eg, bicycle-friendly roadway design, intersections and crossings) along with efforts to promote safe personal behavior (eg, helmet use and following rules of the road) are needed to help reduce injuries among cyclists while sharing the road.
