摘　　要：目的分析患者入院时间对平均住院日的影响。方法检索某三甲医院2011年出院患者的首页信息,利用描述性统计、两独立样本t检验、单因素方差分析和卡方检验方法,对不同时间入院患者的平均住院日进行比较分析。结果不同星期日序(周一至周日),工作日分类(工作日、周末、法定假日),具体时间段(上午、下午、晚上)入院的平均住院日存在显著性统计差异(P<0.05)。周四和周五入院者的平均住院日最长,周一和周日最短;上午、下午和晚上入院者的平均住院日分别为8.13±6.23天、9.45±6.86天、7.28±5.55天;工作日、周末和法定假日的平均住院日分别为8.14天、8.75天、8.86天。结论患者入院时间是影响平均住院日的重要因素。Objective To analyze the influence of the admission time on the average length of stay （ALOS）. Method Through retrieval of the inpatient medical record system in a general hospital in 2011, the ALOS of different admission inpatients were compared using descriptive statistics, two independent sample t - test, one - way ANOVA and chi - square test. Result The ALOS among admissions on different week （ Monday to Sunday ） , workday classification （ workdays, weekends, legal holiday ） and work time （ morning, afternoon, evening） had significant statistical difference （ P 〈 0.05 }. Inpatients with admission on Monday and Sunday had the longest ALOS, while those on Thursday and Friday had the shortest ALOS. The ALOS of inpatients with admission in the morning, afternoon and evening were 8.13 ± 6.23, 9.45 ± 6.86, and 7.28 ± 5.55 daysI respectively ; and those on the workdays, weekends and legal holiday were 8.14, 8.75, and 8.86 days, respectively. Conclusion Admission time is an important factor for ALOS.
