Gunshot wounds sustained during legal intervention versus those inflicted by civilians: A comparative analysis.

ABSTRACT

BACKGROUND: Existing data demonstrate that injuries sustained during legal intervention (LI) differ from those incurred during civilian interpersonal violence (CIV), but gunshot wounds (GSWs) have not yet been specifically examined. This study was undertaken to provide an in-depth analysis of patients shot during LI versus CIV. METHODS: Patients injured by GSW and captured by the National Trauma Data Bank (2007-2017) were included. Exclusions were transfer from outside hospital or self-inflicted, accidental, or undetermined injury intent GSWs. Study groups were defined by injury circumstances GSWs sustained during LI versus CIV. Univariable analysis compared demographics, clinical/injury data, and outcomes. RESULTS: In total, 248,726 patients met inclusion/exclusion criteria 98% (n = 243,150) CIV versus 2% (n = 5,576) LI. Race varied significantly between study groups (p < 0.001). White patients were the most commonly injured race after LI (n = 2,176, 39%). Black patients were the most commonly injured race after CIV (n = 139,067, 57%). Psychiatric disease (9% vs. 2%, p < 0.001) was more common among LI GSWs. The LI patients were more frequently tachycardic (18% vs. 13%, p < 0.001), hypotensive (26% vs. 14%, p < 0.001), and comatose (34% vs. 15%, p < 0.001). The LI patients had higher Injury Severity Scores (13 vs. 9, p < 0.001), required emergent surgical intervention (39% vs. 28%, p < 0.001) and intensive care unit admission (47% vs. 32%, p < 0.001) more often, and had longer hospital stay (4 vs. 3 days, p < 0.001). Mortality was higher after LI (27% vs. 14%, p < 0.001). CONCLUSION: Significant racial and injury severity differences exist between patients shot during LI and CIV. White patients were the most commonly injured race after LI, while Black patients were the most commonly injured race during CIV. In addition, Black patients were overrepresented in both groups when compared with their proportion in the US population. LI patients were more significantly injured, as quantified by clinical, injury, and outcomes variables including increased mortality. Further study of patients shot during LI is needed to better understand this increased burden of injury. LEVEL OF EVIDENCE Prognostic and epidemiological, level IV.
