摘　　要：目的了解重症监护病房老年患者医院感染的危险因素,为采取干预措施、降低医院感染的发生率提供科学依据。方法采用整群抽样方法对在山东省某省级医院重症监护病房(ICU)2004—2010年监护的439例医院感染和713例非医院感染老年患者进行调查。结果感染组与非感染组老年患者比较,性别、年龄、病情分级、基础疾病数量、住院时间、使用免疫制剂、动静脉插管、泌尿道插管、使用呼吸机、气管插管、气管切开、原有糖尿病、原有高血压、原有肺部感染、褥疮、呼吸疾病、脑血管疾病、多发伤、休克情况间差异均有统计学意义(P<0.05);多因素logistic回归分析结果表明,住院时间≥5 d、基础疾病数量≥1种、动静脉插管、气管插管、气管切开和原有肺部感染是ICU老年患者医院感染的危险因素。结论住院时间、基础疾病数量、动静脉插管、气管插管、气管切开和原有肺部感染是ICU老年患者医院感染的危险因素。Objective To investigate the influencing factors of nosocomial infection among elderly patients in intensive care unit（ICU） and to supply scientific evidences for intervention measures to reduce incidence of nosocomial infection in ICU.Methods With cluster sampling method,439 elderly patients with nosocomial infections and 713 elderly patients without nosocomial infections in ICU in a provincial hospital of Shandong province from 2004 to 2010 were investigated.ResultsThere were significant differences in gender,age,disease grading,the number of underlying diseases,hospitalization time,immunosuppressant,vascular catheter,urinary catheter,ventilator,tracheal intubations,tracheotomy,previous diabetes,original hypertension,previous pulmonary infection,pressure ulcers,respiratory disease,cerebrovascular disease,multiple injuries,and the occurrence of shock between infection group and non-infection group（P0.05 for all）.The results of multivariate analysis showed that hospitalization time,the number of underlying diseases,vascular catheter,tracheal intubations,tracheotomy,and previous pulmonary infection were risk factors of nosocomial infection among the elderly patients.Conclusion Hospitalization time,the number of underlying diseases,vascular catheter,tracheal intubations,tracheotomy,and previous pulmonary infection were influencing factors of nosocomial infection among elderly patients in ICU.Relevant control measures should be taken for the influencing factors to reduce the incidence of nosocomial infection.
