多重耐药菌感染目标性监测资料分析

目的 探讨多重耐药菌感染的流行特征和相关因素,为预防控制医院感染提供依据.方法 采用目标性监测方法对2008年10月至2009年10月检测出所有MRSA、VRE、产ESBLs的细菌和多重耐药的鲍曼不动杆菌菌株进行监测.结果 共监测多重耐药菌菌株213株,占全部送检菌株的34.30%,感染部位以下呼吸道为主,耐药菌株多为产ESBLs的细菌,综合ICU感染率最高,≥60岁、患有循环系统疾病、接受侵入性诊疗操作、手术、使用抗生素等是MDRO感染的高危因素.结论 多重耐药菌感染的危险因素众多,需采取综合措施才能有效预防和控制多重耐药菌感染.

An analysis on prospective surveillance data of multidrug-resistance organism infection

Objective To provide medical support for prevention and control of nosocomial infection by exploring the prevalence and risk factors of multidrug-resistance organism (MDRO) infection.Methods Prospective surveillance was conducted from October 2008 to October 2009 to monitor MRSA,VRE,or ESBLs-producing strains and Acinetobacter Baumannwere isolated. Results A total of 213 MDRO strains were detected,which were 34.30％ of all of the isolated strains. The lower respiratory tract was the main infection site and ESBLs-producing strains were the primary germs. MDRO infection occurred most frequently in ICU. Patients aged 60 or older,coexisting circulatory system diseases,use of mechanical ventilation,surgery,and antibiotic use were identified as the risk factors for MDRO infection. Conclusions Various risk factors are attributed to MDRO infection. Comprehensive measures have to be taken incidence of MDRO infection.
