Using data on all inpatients in 16 Michigan hospitals from 1980 through 1985, the clinical effects of a mandatory child restraint law were examined. Time-series analytic techniques revealed a 36% decline in hospitalization for all injuries, with a 25% decline for head injuries, and a 20% decline for extremity injuries for children younger than 4 years. In addition, length of stay declined for children hospitalized secondary to motor vehicle crashes. This study confirms the effectiveness of the child restraint law in Michigan, previously demonstrated by analyses of police records. Current hospital databases may be able to serve as one component for the implementation of comprehensive injury surveillance systems.
利用1980年至1985年密歇根州16家医院所有住院患者的数据，对一项强制性儿童约束法的临床效果进行了研究。时间序列分析技术显示，4岁以下儿童因各种伤害住院的人数下降了36%，头部受伤住院人数下降了25%，四肢受伤住院人数下降了20%。此外，因机动车撞车事故住院的儿童住院时间缩短。这项研究证实了密歇根州儿童约束法的有效性，此前警方记录分析已证明这一点。当前的医院数据库或许能够作为实施全面伤害监测系统的一个组成部分。
