Helmet use patterns in urban trauma centers in New York City: A retrospective review of patients from 2013 to 2022.

Background: There has been a recent rise in micromobility device use, which can be attributed to the increase in delivery services, faster 2-wheeled vehicles, and COVID. However, the rate of helmet use is largely unknown. We aim to document the trends and identify risk factors for helmet use over the last decade in urban trauma centers in New York City to find opportunities for intervention.
