先前关于机动车碰撞后生存的种族和民族差异的研究仅检查了基于人群的死亡率或仅限于住院患者。在当前的研究中，我们按种族/民族检查了车祸生存率的3个组成部分：总生存率、到达医院的生存率和住院患者的生存率。从2000年到2008年，来自国家汽车抽样系统耐撞数据系统的9年数据被用于检查年龄为>= 15岁的严重受伤的白人、非西班牙裔黑人和西班牙裔司机（损伤严重程度评分为>= 9）。通过使用多变量logistic回归，我们发现司机的种族/民族与车祸中受伤后的总体生存率没有显著相关(对于黑人，优势比(OR) = 0.69, 95%置信区间（CI）： 0.36, 1.32；西班牙裔，OR = 1.00, 95% Cl: 0.59, 1.72)，与白人相比，黑人和西班牙裔在医院接受治疗的存活率相同（黑人，OR = 1.00, 95% CI: 0.52, 1.93；西班牙裔，OR = 1.13, 95% Cl: 0.71, 1.79）。然而，在医院接受治疗的患者中，黑人存活30天的可能性比白人低50% （OR = 0.50, 95% Cl: 0.33, 0.76）。黑人严重交通伤害后的生存差异似乎发生在住院后，而不是院前生存。
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% Cl: 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% Cl: 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% Cl: 0.33, 0.76). The disparity in survival after serious traffic injuries among blacks appears to occur after hospitalization, not in prehospital survival.
