摘　　要：目的评估日间手术的开展对平均住院日的作用效果，为科学地缩短平均住院日提供参考。方法收集2011年11月至2016年12月中南大学湘雅医院连续开展日间手术较多的6个科室的平均住院日数据，采用间断时间序列数据的分段回归模型，分析开展日间手术前后平均住院日的变化趋势。结果开展日间手术后，平均住院日每月下降0.071天，较开展前每月降幅增加0.049天（P〈0.001）;口腔科、耳鼻喉科、普外科、肝胆肠中心的平均住院日下降最明显，较开展前每月降幅分别增加0.110天（P〈0.001）、0.049天（P＝0.008）、0.075天（P〈0.001）、0.057天（P＝0.003）。结论日间手术的开展缩短了平均住院日，有助于提高医院资源利用率。ObjectiveTo evaluate the effects of day surgery on average days of stay, and to provide scientific basis for shorter average days of stay. MethodsData of average days of stay from November 2011 to December 2016 were extracted from 6 departments, Xiangya Hospital, Central South University. Segmented regression analysis of interrupted time series was used to analyze the trend of average days of stay of pre-and post-day surgery.ResultsThanks to the application of day surgery, average days of stay decreased by 0.071 days per month, and the monthly decline increased by 0.049 days （P〈0.001） than before. Average days of stay in the department of stomatology, ear-nose-throat, general surgery and hepatobiliary ＆ enteric surgery research center were the most obvious, and the monthly decline increased by 0.110 days （P〈0.001）, 0.049 days （P=0.008） , 0.075 days （P〈0.001）, and 0.057 days （P=0.003）, respectively than before.ConclusionsDay surgery could decrease average days of stay, enhancing the utilization of hospital resources.
