Epidemiology of nonpowdered firearm injury in high-income countries: a scoping review
摘要
Nonpowdered firearms discharge projectiles at forces capable of inflicting serious harm. Regulations governing access and use of non-powdered firearms vary by jurisdiction, and the injury burden resulting from these weapons is not well described and may also vary by region. Measurement and comparison of nonpowdered firearm injury rates is important to inform injury prevention strategies. We aimed to describe published rates of nonpowdered firearm injuries across Organization for Economic Co-Operation and Development (OECD) countries.
MethodsWe searched MEDLINE, EMBASE, the Cochrane Library, Web of Science, Scopus, and Criminal Justice Abstracts databases from inception to April 7, 2023 for sources reporting population-level rates of nonpowdered firearm injuries (ball bearing, airsoft, or pellet guns). We excluded case reports, case series, and experimental studies. We identified grey literature through targeted webpages and Google search engine. We extracted population and injury characteristics, rates of injury, and intent and severity data.
ResultsWe identified 31 sources from five countries (United States, Canada, United Kingdom, Finland, and Sweden) that reported rates of nonpowdered firearm injury. Data were heterogenous in terms of population, year (range: 1970–2021), injury type (ocular, head/neck, all injuries). Most data sources reported high unintentional injury burden, however, a substantial number of injuries reported were due to assaults. Younger age groups (5- to 9- and 10- to 14-year-olds) were disproportionately impacted.
ConclusionsNonpowdered firearms are an important cause of injury. Gaps in reporting and lack of uniformity exist in defining these injuries and must be addressed to inform injury prevention strategies.
