The effect of resident work-hour restriction on patient outcome remains controversial.
Demographic data, mechanism of injury, length of hospital stay length of intensive care unit (ICU) stay, ventilator days, mortality, and complication data were prospectively collected for 11 months before and 11 months after institution of a rotating night-float system. Seven attending surgeons reviewed all complications and categorized each as preventable, potentially preventable, or nonpreventable.
Both study periods were comparable with respect to demographic data, mean Injury Severity Score, mechanism of injury, and admissions. Limitation of resident work hours had no effect on length of hospital or ICU stay, ventilator days, or mortality. Work-hour restrictions did not increase or decrease the total number of complications nor did it alter the distribution of those determined to be preventable or potentially preventable.
Resident work-hour restrictions were not associated with significant improvement or deterioration in patient outcome.
住院医师工作时间限制对患者预后的影响仍存在争议。
前瞻性收集实施轮班夜间值班制度前11个月和后11个月的人口统计学数据、损伤机制、住院时间、重症监护病房（ICU）住院时间、呼吸机使用天数、死亡率及并发症数据。七位主治外科医生对所有并发症进行评估，并将其分类为可预防、可能可预防或不可预防。
两个研究时间段在人口统计学数据、平均损伤严重程度评分、损伤机制及入院情况方面具有可比性。住院医师工作时间的限制对住院时间或ICU住院时间、呼吸机使用天数或死亡率没有影响。工作时间限制并未增加或减少并发症的总数，也未改变那些被确定为可预防或可能可预防并发症的分布。
住院医师工作时间限制与患者预后的显著改善或恶化无关。
