摘　　要：[目的]了解某院医院感染危险因素,为医院感染的控制和目标性监测提供科学依据。[方法]2008年1～12月每月下旬进行一次医院感染现患率调查的同时进行医院感染危险因素调查,并对结果进行统计分析。[结果]医院感染平均现患感染率和例次感染率分别为3.89%和4.19%;部位分布前5位为呼吸系统、泌尿系统、口腔、血液、手术切口;科室分布前5位依次为ICU、内科、外科、肿瘤科、儿科。多因素非条件Logistic回归分析显示:男性、年龄≥60岁、有基础病、及侵入性操作:动静脉插管、使用呼吸机、泌尿道插管、胃插管、气管切开会显著增加发生医院感染的风险。[结论]医院感染的高危因素为男性、年龄≥60岁、侵入性操作、基础病,医院感染目标性监测应针对这些因素而确立。[Objective] To explore the incidence of nosocomial infection（NI）and its risk factors in our hospital,and can offer the evidence of quality control and target surveillance of NI.[Methods] the prevalence of hospital infection and its risk factors were investigated every month from January to December 2008,and the result was statistic analyzed.[Results] The average prevalence rate of NI and case prevalence rate were 3.89% and 4.19%,respectively.The top five sites of NI were respiratory system,urinary system,oral cavity,blood and surgical incision.The top five departments in sequence were ICU,medical department,surgical department,department of oncology,and pediatrics department.The analysis of multivariate un-conditional logistic regression showed that male,age over 60-year,basic diseases,invasive procedures including arterio-ve-nous cannulation,ventilator,urinary catheterization,gastric intubation and tracheotomy were significantly associated with the increased risk of NI.[Conclusion] Male,age over 60-year,invasive procedures,basic diseases are risk factors of NI.Target surveillance of NI should be established for those factors.
