Racial Disparities in Diagnosis of Concussion and Minor Head Trauma and Mechanism of Injury in Pediatric Patients Visiting the Emergency Department

Abstract

To determine if racial/ethnic differences exist in the diagnosis and mechanism of injury among children and adolescents visiting the emergency department (ED) for concussion and minor head trauma (MHT). A retrospective, cross-sectional study of patient (age ≤19years) visits to the ED for concussion between 2010-2015, using the National Hospital Ambulatory Medical Care Survey, was completed. The primary study exposure was race/ethnicity. Outcome measures included ED visits that resulted in a concussion/MHT diagnosisand mechanism of injury. Mechanism categories included sport, motor vehicle collision, fall, assault, and other mechanism. A multivariable logistic regression and multinomial logistic regression were conducted to assess relationships between race/ethnicity and outcomes. Findings were weighted to reflect population estimates. In total, 1263 child/adolescent visits for concussion/MHT were identified, representing an estimated 6.6 million child/adolescent visits nationwide. Compared with non-Hispanic White pediatric patients, non-Hispanic Black patients were least likely to have an ED visit for a concussion/MHT (P<.001; OR, 0.66; 95% CI, 0.52-0.83) The odds of non-Hispanic Black children/adolescents (OR, 3.80; 95% CI, 1.68-8.55) and children/adolescents of other race/ethnicity (OR, 4.93; 95% CI, 1.09-22.23) sustaining a concussion/MHT resulting from assault vs sport was higher. Amid the emerging focus on sport-related concussion, these ethnic/racial differences in ED diagnosis of concussion/MHT demonstrate sociodemographic differences that warrant further attention. Assault may be a more common mechanism of concussion among children/adolescents of a racial minority.
