Youth and Young Adult Victims of Interpersonal Violence at LA County + USC Medical Center: A Review of Epidemiology and Recidivism

Abstract

Youth and young adult interpersonal violence (IPV) is a unique clinical challenge which merits study. This study defined the demographics and clinical outcomes of youth and young adult victims of IPV presenting to our hospital while examining violent injury recidivism. We reviewed patients aged 10 to 30 years admitted to our trauma bay as a victim of gunshot wound (GSW), stabbing wound, or blunt assault from 1998 to 2015 (n = 12,549). Logistic regression analysis was conducted to compare patient mortality across demographic characteristics, and Cox proportional hazards regression was used to determine risk factors for recidivism. Male (92%) and Hispanic patients (75%) constituted the majority of admissions. We observed differences in the mortality rate by gender (9% in males vs 5% in females, P < 0.001), race/ethnicity (5% non-Hispanic white vs 9% Hispanic, P = 0.001), insurance status (3% insured vs 10% uninsured, P < 0.001), and mechanism of injury (13% GSW, 2% stabbing wound, and 0.3% blunt assault, P < 0.001). Male gender, younger age, GSW, and amphetamine placed patients at higher risk for IPV recidivism (P < 0.05). This study demonstrates the need to better understand how demographics and economics are associated with youth and young adult IPV. In addition, future IPV prevention and intervention initiatives can be tailored to suit the unique needs of our population.
