Safety Factors and Patterns of Bicycle Trauma in a Tertiary Level ۱ Trauma Center in Boston, Massachusetts: A Retrospective Review and Survey Study

Objectives: Increasing bicycle ridership is accompanied by ongoing bicycle-related accidents in many urban cities. There is a need for improved understanding of patterns and risks of urban bicycle usage. We describe the injuries and outcomes of bicycle-related trauma in Boston, Massachusetts, and determine accident-related factors and behaviors associated with injury severity.Methods: We conducted a retrospective review via chart review of ۳۱۳ bicycle-related injuries presenting to a Level ۱ trauma center in Boston, Massachusetts. These patients were also surveyed regarding accident-related factors, personal safety practices, and road and environmental conditions during the accident.Results: Over half of all cyclists biked for commuting and recreational purposes (۵۴%), used a road without a bike lane (۵۸%), and a majority wore a helmet (۹۱%). The most common injury pattern involved the extremities (۴۲%) followed by head injuries (۱۳%). Bicycling for commuting rather than recreation, cycling on a road with a dedicated bicycle lane, the absence of gravel or sand, and use of bicycle lights were all factors associated with decreased injury severity (p<۰.۰۵). After any bicycle injury, the number of miles cycled decreased significantly regardless of cycling purpose.Conclusion: Our results suggest that physical separation of cyclists from motor vehicles via bicycle lanes, regular cleaning of these lanes, and usage of bicycle lights are modifiable factors protective against injury and injury severity.Safe bicycling practices and understanding of factors involved in bicycle-related trauma can reduce injury severity and guide effective public health initiatives and urban planning. Level of evidence: IV
