Public Bicycle Share Programs and Head Injuries

This article reports on a study that investigated head injuries that occur among users of North American public bicycle share programs (PBSPs), which typically do not offer helmets with the bike rentals. The authors analyzed trauma center data for bicycle-related injuries from 5 cities with PBSPs (Montreal, Washington D.C., Minneapolis, Boston, Miami Beach) and compared that data to 5 similar cities (Vancouver, New York, Milwaukee, Seattle, Los Angeles). The authors used logistic regression models to compare the odds that admission for a bicycle-related injury would involve a head injury 24 months before PBSP implementation and 12 months afterward. The study showed that, in PBSP cities, the proportion of head injuries among bicycle-related injuries increased from 42.3% before PBSP implementation to 50.1% after. This proportion in comparison cities remained similar before (38.2%) and after (35.9%) implementation. The authors conclude that steps should be taken to make helmets available with PBSPs. They offer a discussion of strategies to address some of the difficult logistics of providing helmets to PBSP riders.
