Abstract: Objectives: The objective was to determine whether a child's race or ethnicity as determined by the treating physician is independently associated with receiving abdominal computed tomography (CT) after blunt torso trauma. Methods: We performed a planned secondary analysis of a prospective observational cohort of children < 18 years old presenting within 24 hours of blunt torso trauma to 20 North American emergency departments (EDs) participating in a pediatric research network, 2007-2010. Treating physicians documented race/ethnicity as white non-Hispanic, black non-Hispanic, or Hispanic. Using a previously derived clinical prediction rule, we classified each child's risk for having an intra-abdominal injury undergoing acute intervention to define injury severity. We performed multivariable analyses using generalized estimating equations to control for confounding and for clustering of children within hospitals. Results: Among 12,044 enrolled patients, treating physicians documented race/ethnicity as white non-Hispanic (n = 5,847, 54.0%), black non-Hispanic (n = 3,687, 34.1%), or Hispanic of any race (n = 1,291, 11.9%). Overall, 51.8% of white non-Hispanic, 32.7% of black non-Hispanic, and 44.2% of Hispanic children underwent abdominal CT imaging. After age, sex, abdominal ultrasound use, risk for intra-abdominal injury undergoing acute intervention, and hospital clustering were adjusted for, the likelihood of receiving an abdominal CT was lower (odds ratio [OR] = 0.8, 95% confidence interval [CI] = 0.7 to 0.9) for black non-Hispanic than for white non-Hispanic children. For Hispanic children, the likelihood of receiving an abdominal CT did not differ from that observed in white non-Hispanic children (OR = 0.9, 95% CI = 0.8 to 1.1). Conclusions: After blunt torso trauma, pediatric patients identified by the treating physicians as black non-Hispanic were less likely to receive abdominal CT imaging than those identified as white non-Hispanic. This suggests that nonclinical factors influence clinician decision-making regarding use of abdominal CT in children. Further studies should focus on explaining how patient race can affect provider choices regarding ED radiographic imaging.
