Pediatric Firearm-Related Traumatic Brain Injury in United States Trauma Centers

Abstract

Abstract INTRODUCTION Firearm injury is a leading cause of death and disability in the American youth. Epidemiology and outcomes following gunshot wound to the head (GSWH) are in need of systematic characterization. Here, we analyzed pediatric GSWH to identify predictors of prolonged hospitalization, morbidity and mortality. METHODS All patients < 18 yr with GSWH in the National Sample Program (NSP) of the National Trauma Data Bank (NTDB) from 2003 to 2012 were identified. Variables included injury intent, firearm choice, injury site, age, sex, race, health insurance, geographic region, trauma center level, isolated TBI, emergency department (ED) hypotension, Glasgow Coma Scale (GCS), and Injury Severity Score (ISS). Outcomes were hospital length of stay (HLOS), morbidity and mortality. Odds ratios (OR), mean increase/decrease (B), and 95% confidence intervals (CI) were reported. Statistical significance was assessed at a < 0.001 accounting for multiple comparisons. RESULTS In a weighted sample of 2847 pediatric GSWHs, age was 14.8 ± 3.3 yr, 79.2% were male, and 59.0% had severe traumatic brain injury (TBI; Glasgow Coma Scale [GCS] score 3-8). Assault (63.0%), handgun as firearm (45.6%), and injury in residential areas (40.6%) were most common. HLOS was 11.6 ± 14.4 d for the survivors, for which suicide injuries had longer hospitalization (B = 5.9 day increase, 95% CI [3.3-8.6], P < .001) relative to accidents. The overall mortality was 45.1%, and was greater with suicide intent (mortality = 71.5%, P < .001) and shotgun as firearm (mortality = 56.5%, P < .001). Lower GCS, higher ISS, and hypotension predicted poorer outcomes. Management at level II centers was associated with lower odds of returning home (OR = 0.3, [0.2-0.5], P < .001). CONCLUSION From 2003 to 2012, the proportion of accidental injuries decreased while suicides increased. The overall mortality was 45%, with hypotension, cranial and overall injury severity, and suicide intent being associated with poor prognosis. Patients treated at level II trauma centers had lower odds of being discharged home. Improved risk screening, parental education and standardization of critical care management are needed.
