Objective

To characterize hospitalization costs attributable to gun-related injuries in children across the US.

Study design

The 2005-2017 National Inpatient Sample was used to identify all pediatric admissions for gunshot wounds (GSW). Patients were stratified by International Classification of Diseases procedural codes for trauma-related operations. Annual trends in GSW hospitalizations and costs were analyzed with survey-weighted estimates. Multivariable regressions were used to identify factors associated with high-cost hospitalizations.

Results

During the study period, an estimated 36 283 pediatric patients were admitted for a GSW, with 43.1% undergoing an operative intervention during hospitalization. Admissions for pediatric firearm injuries decreased from 3246 in 2005 to 3185 in 2017 (NPtrend < .001). The median inflation-adjusted cost was $12 408 (IQR $6253-$24 585). Median costs rose significantly from $10 749 in 2005 to $16 157 in 2017 (P < .001). Compared with those who did not undergo surgical interventions, operative patients incurred increased median costs ($18 576 vs $8942, P < .001). Assault and self-harm injuries as well as several operations were independently associated with classification in the highest cost tertile.

Conclusions

Admissions for pediatric firearm injuries were associated with a significant socioeconomic burden in the US, with increasing resource use over time. Pediatric gun violence is a major public health crisis that warrants further research and advocacy to reduce its prevalence and social impact.
