Assault in children admitted to trauma centers: Injury patterns and outcomes from a 5-year review of the national trauma data bank

Abstract

Importance: While assault is commonly reported or suspected in children with traumatic wounds, a recent overview of these injuries, especially those requiring trauma surgery consultation is lacking in the literature.

Objectives: Explore the incidence, demographics and injury patterns of children presenting to trauma centers following an assault.

Design: Retrospective review of the National Trauma Data Bank 2007 to 2011.

Setting and participants: Subjects up to 18 years old with "assault" reported as the intent of injury. Patients were divided into infants (<2 years), young children (2-5 years), children (6-11 years), and adolescents (12-18 years).

Main outcomes and measures: Mechanism of injury, injury severity and mortality based on age groups and race.

Results: Of 609,207 children, 58,299 (9.6%) were victims of an assault. The median age was 16 years and 81% were male, with a median injury severity score (ISS) of 8. The majority of patients were adolescents (76%), followed by infants (17%) and young children (4%). There was a stepwise increase in the proportion of assaulted Black children with increasing age (23.2% for infants and up to 46.7% for adolescents, trend p < 0.01, effect size: 0.175) while the opposite applied for White children (46.0% for infants and down to 19.5% for adolescents, trend p < 0.01, effect size: -0.230). With increasing age, White subjects had the highest trend of being assaulted during an unarmed fight or brawl (p < 0.01, effect size: 0.393), while for Black victims the highest trend was noted for assault with a firearm (p < 0.01, effect size: 0.323). Almost 2 out of 3 infants sustained severe head trauma (59%). The overall mortality was 8%, highest among young children, where it reached 16% (p < 0.01).

Conclusions: Up to 10% of children admitted following trauma are victims of assault with traumatic brain injuries predominant in infants and firearm injuries predominant in adolescents. Injury patterns largely correlate to age and race. Assault in children is associated with a high mortality risk. These data highlight the magnitude of the problem and calls for further involvement of trauma surgeons to improve outcomes, bring awareness and promote preventative strategies to eliminate assault in children.
