目的分析加强监护病房(ICU)病人的收治时间(工作日或周末)与住院病死率的相关关系。方法回顾1999年7月26日至2002年12月30日北京协和医院ICU收治的1840例病人临床资料,采用逻辑回归方法分析住院死亡的危险因素。结果周五(OR 1．801,95％CI 1．101- 2．945,P=0．019)、周六(OR 2．569,95％CI 1．485-4．445,P=0．001)及周日(OR 2．542,95％CI 1．377-4．691,P=0．003)收治病人的住院病死率显著多于周四收治的病人,采用APACHEⅡ诊断分类权重进行校正后住院病死率差异仍有统计学意义,但采用多因素校正后,周五(OR 1．191,95％CI 0．628-2．259,P=0．593)、周六(OR 1．107,95％CI 0．528-2．324,P:0．787)及周日(OR 0．571, 95％CI 0．240-1．360,P=0．206)收治病人病死率差异无统计学意义。结论ICU收治病人的时间与住院病死率无关。
Objective To analyze the relationship between intensive care unit (ICU) admission time (weekdays or weekends) and hospital mortality. Methods The clinical data of 1840 patients admitted to ICU of Peking Union Medical College Hospital from July 26, 1999 to December 30, 2002 were retrospectively analyzed. Logistic regression was used to analyze the risk factors of in-hospital mortality. Results Friday (OR 1.801, 95% CI 1.101- 2.945, P = 0.019), Saturday (OR 2.569, 95% CI 1.485-4.445, P = 0. 001) and on Sunday (OR 2.542, 95% CI 1.377-4.691, P = 0.003) were significantly higher than those admitted on Thursday, and adjusted using APACHE II diagnostic classification weights The difference in post-hospital mortality was still statistically significant, but after adjusted for multiple factors on Friday (OR 1.191; 95% CI 0.628-2.259, P = 0.593), on Saturday (OR 1. 107,95% CI 0.528-2.324, P: 0.787) and on Sunday (OR 0.571, 95% CI 0.240-1.360, P = 0.206) No statistical significance. Conclusion ICU admitted to the patient’s time and hospital mortality has nothing to do.
