BackgroundThe number of black trauma deaths attributable to racial disparities is unknown. The objective of this study was to quantify the excess mortality experienced by black patients given disparities in the risk of mortality.Materials And MethodsWe performed a retrospective analysis of patients aged 16-65 y with blunt and penetrating injuries, who were included in the National Trauma Data Bank from 2007-2010. Generalized linear modeling estimated the relative risk of death for black patients versus white patients, adjusting for known confounders. This analysis determined the difference in the observed number of black trauma deaths at Level I and II centers and the expected number of deaths if the risk of mortality for black patients had been equivalent to that of white patients.ResultsA total of 1.06 million patients were included. Among patients with blunt and penetrating injuries at Level I trauma centers, white males and females had a relative risk of death of 0.82 (95% confidence interval [CI], 0.80-0.85) and 0.78 (95% CI, 0.74-0.83), respectively, compared with black patients. Similarly, at Level II trauma centers, white males and females had a relative risk of death of 0.84 (95% CI, 0.80-0.88) and 0.82 (95% CI, 0.73-0.91). Overall, of the estimated 41,613 deaths that occurred at Level I and II centers, 2206 (5.3%) were excess deaths among black patients.ConclusionsOver a 4-y period, approximately 5% of trauma center deaths could be attributed to racial disparities in trauma outcomes. These data underscore the need to better understand and intervene against the mechanisms that lead to trauma outcomes disparities.Copyright © 2013 Elsevier Inc. All rights reserved.
