Abstract
Introduction
Differences in head injury severity may not be fully appreciated in child abuse victims. The purpose of this study was to determine if differential findings on initial head computed tomography (CT) scan could explain observed differential outcome by race.
Methods
We identified 164 abuse patients from our trauma registry with an Injury Severity Score (ISS) ≥ 15. Their initial head CT scan was graded from 1 to 4 (normal to severe). Statistical analysis was performed to asses the correlation between race, head CT grade, Glascow Coma Scale (GCS) score, and mortality.
Results
Overall mortality was 17%: 11% for white children, 32% for African-American children (P < .05). In review of the head CT scans there was no difference by race in types of injuries or head CT grade. Using a multivariate regression model, African-American race remained an independent risk factor for mortality with an odd ratio of 4.3 (95% confidence interval [CI] 1.6–11.5).
Conclusion
African-American children had a significantly higher mortality rate despite similar findings on initial head CT scans. Factors other than injury severity may explain these disparate outcomes.
