腹部恶性肿瘤术后医院感染危险因素Logistic回归分析

目的调查分析腹部恶性肿瘤患者术后医院感染的危险因素,以制定预防和控制医院感染的方案。方法回顾性对照分析2007年3月~2009年3月医院腹部恶性肿瘤术后感染与非感染患者病例,包括:性别、年龄、是否患有糖尿病、术前住院天数、麻醉ASA分级、手术时间、引流管数量、是否有中央静脉插管、术后住院天数等,并采用SPSS软件包进行Logistic回归方法统计。结果Logistic回归分析显示,患糖尿病、手术时间≥230 min、术前住院时间≥6 d、麻醉ASA≥Ⅲ级4个变量与术后医院感染的相关性差异有统计学意义。结论结果中的4个变量均是术后医院感染的危险因素,术后医院感染增加了患者的术后住院时间。

Risk Factors of Nosocomial Infection in Postoperative Patients with Abdominal Cancer

OBJECTIVE Nosocomial infection is a severe complication after the surgery of abdominal malignant tumor in digestive organs. Finding out independent risk factors is important for prevention of infection.METHODS In this study all the patients after the surgery of abdominal malignant tumor in digestive organs from Mar 2007 to Mar 2009 in the Beijing Shijitan Hospital were selected. The investigated variables included patients of Anesthesiologists (ASA) grade, surgery type, surgery time, number of drainage tube, central venous catheters of Anesthesi010gists(ASA)grade,surgery type,surgery time,number of drainage tube,central venous cathetersand postsurgery time in hospital. The retrospective case control analysis was summeirized and the statistical treatment was executed by SPSS10. 10 software. RESULTS Four variables were discovered in connection with postsurgery nosocomial infection,including diabetes,surgery time≥230 minutes,presurgery time in hospital≥6 days and anesthesia ASA grade≥Ⅲ.CONCLUSIONS The four variables are the risk factors for postsurgery nosocomial infection, which results in increase of duration in hospital.
