Firearm assault in Philadelphia 2005–2014: a comparison of police and trauma registry data

摘要

BackgroundFirearm injury is a major public health burden in the USA. Absent a single, reliable data source, researchers have attempted to describe firearm injury epidemiology using trauma registry data. To understand the implications of this approach, we compared trends in firearm assault incidence and case-fatality in Philadelphia over 10 years from two sources: the Pennsylvania Trauma Outcomes Study (PTOS), Pennsylvania’s state-mandated trauma registry, and the Philadelphia Police Department database (PPD) of firearm assaults.
