摘　　要：目的了解综合性重症监护病房医院感染情况及发展特点,分析引起医院感染的影响因素。为采取干预措施,降低医院感染的发生率提供科学依据。方法对2004年1月～2009年12月连续6年某三级甲等教学医院综合性ICU所有住院患者的医院感染进行回顾性研究和前瞻性监测。共调查1718例住院病人,其中558例为医院感染组(nosocomial infection,NI),1160例无任何感染者为非NI组。所有数据采用SPSS11.5统计软件进行处理。两组资料进行单因素卡方检验后,用非条件logistic回归模型进行多元分析。结果多因素结果筛选出病情分级、住院时间、原有肺部感染、气管插管、气管切开是医院感染的独立影响因素。结论影响医院感染的因素较多,根据监测结果采取针对性干预措施,可降低医院感染发生率,保障患者医疗安全。Objective To investigate the actual state and the characteristics of nosocomial infections （NI） in integrated ICU,To analyse the Influencing factors of NI.To supply scientific evidences for intervening measures to reduce the incidence of NI in integrated ICU.Methods NI of all the integrated ICU inpatients in a tertiary teaching hospital during 6 years from January 2004 to December 2009 were retrospectively studied and prospectively surveyed.We investigated 1718 inpatients of which 558 suffered from NI and 1160 patients without any infection were non-NI.All the data were analyzed with SPSS （version 11.5）.After we used single-factor Chi-square test to check out the data of the two groups we multivariatly analyzed the data with non-conditional logistic regression mode.Results The analysis of selected multi-factor showed that the independent Influencing factors of NI were the grading of disease,length stay,the original lung infection,tracheal intubation and tracheotomy.Conclusion We should pay much more attention to monitor the influencing factors and take targeted intervention to reduce the incidence of infection and insure patients＇ medical safty.
