National Trends and Cost Burden of Surgically Treated Gunshot Wounds in the US

BACKGROUND: Gun violence remains a major burden on the US healthcare system, with annual cost exceeding $170 billion. Literature on the national trends in cost and survival of gun violence victims requiring operative interventions is lacking. STUDY DESIGN: All adults admitted with a diagnosis of gunshot wound requiring operative intervention were identified using the 2005-2016 National Inpatient Sample. The ICD Injury Severity Score, a validated prediction tool, was used to quantify the extent of traumatic injuries. Survey-weighted methodology was used to provide national estimates. Hospitalizations exceeding the 66th percentile of annual cost were considered as high-cost tertile. Multivariable logistic regressions with stepwise forward selection were used to identify factors associated with mortality and high-cost tertile. RESULTS: During the study period, 262,098 admissions met inclusion criteria with a significant increase in annual frequency and decrease in ICD Injury Severity Scores. A decline in mortality (8.6% to 7.6%; parametric test of trend = 0.03) was accompanied by increasing mean cost ($25,900 to $33,000; nonparametric test of trend < 0.001). After adjusting for patient and hospital characteristics, head and neck (adjusted odds ratio 31.2; 95% CI, 11.0 to 88.4; p < 0.001), vascular operations (adjusted odds ratio 24.5; 95% CI, 19.2 to 31.1; p < 0.001), and gastrointestinal (adjusted odds ratio 27.8; 95% CI, 17.2 to 44.8; p < 0.001) were independently associated with high-cost tertile designation compared with patients who did not undergo these operations. CONCLUSIONS: During the past decade, the increase in gun violence and severity has resulted in higher cost. Operations involving selected surgical treatments incurred higher in-hospital cost. Given the profound economic and social impact of surgically treated gunshot wounds, policy and public health efforts to reduce gun violence are imperative.
