Emergency department utilization by youth before and after firearm injury.

Background: Emergency department (ED) visits may serve as opportunities for firearm injury prevention and intervention efforts. Our objective was to determine ED utilization by youth before and after firearm injury.

Methods: We performed a retrospective cohort study of ED encounters by youth (0-18 years old) with firearm injury from eight states using the 2019 State ED and Inpatient Databases. Our primary outcome was an ED encounter (1) 90 days before or (2) 90 days after index injury. We used generalized estimating equations, accounting for hospital clustering, to determine associations between ED utilization and ED type (pediatric vs. general), youth age, sex, race and ethnicity, urbanicity, and insurance status.

Results: We identified 1035 ED encounters for firearm injury (median [IQR] age 17 (15-18) years, 85.3% male, 63.3% non-Hispanic Black, 68.6% publicly insured, 90.5% living in a metropolitan area, 52.8% general ED). In the 90 days before an index injury, 12.8% of youth had an ED encounter; of these, 68.2% occurred in general EDs, and 18.2% were for trauma. In the 90 days after an index injury, 22.1% of youth had an ED encounter; of these, 50.0% occurred in general EDs, and 22.6% were for trauma. We found no significant association between ED type and ED utilization patterns. Few youths changed ED type across longitudinal encounters.

Conclusions: Youth have high rates of ED utilization before and after firearm injury. Half of firearm-injured youth receive their emergency care exclusively in general EDs. Implementing firearm injury prevention and intervention efforts in all ED settings is critical.
