摘　　要：目的了解重症监护病房(ICU)患者的医院感染发生率、危险因素、预防措施,防止医院感染发生。方法采取目标性监测方法,对医院2005年11月-2009年6月ICU住院患者发生医院感染的情况进行调查,用ASA法调整医院感染发病率,并对侵入性操作相关感染进行分析。结果833例ICU住院>48 h的患者中,发生医院感染92例,医院感染发生率为11.04%,患者日感染率为5.73%,根据病情的平均严重程度经ASA法调整后的医院感染患者日感染率为4.43%。检出病原菌145株,主要为革兰阴性杆菌(56.55%),鲍氏不动杆菌占VAP致病菌的百分率逐年上升。结论ICU患者是医院感染易感人群,医院感染菌以鲍氏不动杆菌为主且有多药耐药性,目标性监测可以有效地降低ICU患者医院感染的发生。OBJECTIVE To investigate the incidence of nosocomial infection in ICU patients, risk factors, and measures to prevent infection. METHODS The nosocomial infection of ICU patients in the hospitals from Nov 2005 to Jun 2009 was investigated using the method of target monitoring. The nosocomial infection rate was regulated by the method of ASA. The invasive procedure and the associated infection rate were analyzed. RESULTS Among 833 inpatients in ICU,92 suffered from nosocomial infection, The nosocomial infection rate was 11.04%. and the nosocomial infection rate per day was 4.43% after modified by the method of ASA. The incidence of patients was 5. 37%. Totally 145 strains of bacteria were isolated, and the dominant pathogens were Gram-negative bacilli （56.55%）. CONCLUSIONS The patients in ICU are susceptible population of nosoeomial infection, A. baumannii is the dominating pathogen to cause nosocomial infection in intensive care units. Target monitoring in ICU is an effective surveillance method to reduce the prevalence of nosocomial infection.
