[BDSP. Notice produite par INIST-CNRS rEAlR0xq. Diffusion soumise à autorisation]. Prior studies on racial and ethnic disparities in survival after motor vehicle crashes have examined only population-based death rates or have been restricted to hospitalized patients. In the current study, we examined 3 components of crash survival by race/ethnicity : survival overall, survival to reach a hospital, and survival among those hospitalized. Nine years of data (from 2000 through 2008) from the National Automotive Sampling System Crashworthiness Data System were used to examine white non-Hispanic, black non-Hispanic, and Hispanic drivers aged>15 years with serious injuries (injury severity scores of>=9). By using multivariable logistic regression, we found that a driver's race/ethnicity was not significantly associated with overall survival after being injured in a crash (for blacks, odds ratio (OR)=0.69,95% confidence interval (CI) : 0.36,1.32 ; for Hispanics, OR=1.00,95% CI : 0.59,1.72), and blacks and Hispanics were equally likely to survive to be treated at a hospital compared with whites (for blacks, OR=1.00,95% CI : 0.52,1.93 ; for Hispanics, OR=1.13,95% CI : 0.71,1.79). However, among patients who were treated at a hospital, blacks were 50% less likely to survive 30 days compared with whites (OR=0.50,95% CI : 0.33,0.76). The disparity in survival after serious traffic injuries among blacks appears to occur after hospitalization, not in prehospital survival.
