We studied National Trauma Data Bank data to determine the effectiveness of car safety devices in reducing mortality and injury severity in 184,992 patients between 1988 and 2004. Safety device variables were seat belt used plus air bag deployed; only seat belt used; only air bag deployed; and, as explicitly coded, no device used. Overall mortality was 4.17%. Compared with the no-device group, the seat-belt-plus-air-bag group had a 67% reduction in mortality (adjusted odds ratio [AOR], 0.33; 99% confidence interval [CI], 0.28-0.39), the seatbelt- only group had a 51% mortality reduction (AOR, 0.49; 99% CI, 0.45-0.52), and the air-bag-only group had a 32% mortality reduction (AOR, 0.68, 99% CI, 0.57-0.80). Injury Severity Scores showed a similar pattern.
我们研究了国家创伤数据库的数据，以确定1988年至2004年间184992例患者中汽车安全装置在降低死亡率和损伤严重程度方面的有效性。安全装置变量包括使用安全带并展开安全气囊；仅使用安全带；仅展开安全气囊；以及明确记录的未使用任何装置。总体死亡率为4.17%。与未使用装置组相比，使用安全带并展开安全气囊组的死亡率降低了67%（调整优势比[AOR]为0.33；99%置信区间[CI]为0.28 - 0.39），仅使用安全带组的死亡率降低了51%（AOR为0.49；99% CI为0.45 - 0.52），仅展开安全气囊组的死亡率降低了32%（AOR为0.68，99% CI为0.57 - 0.80）。损伤严重程度评分显示出类似的模式。
