重症监护室医院获得性泌尿道感染病原菌分析

Pathogens causing healthcareassociated urinary tract infection in intensive care unit patients

摘要:

目的了解重症监护室（ICU）医院获得性泌尿道感染及病原菌情况，为预防和控制ICU患者泌尿道医院感染提供科学依据。方法对2013年32所医院ICU泌尿道医院感染目标监测资料进行分析。结果共监测ICU住院患者23 680例，发生医院获得性泌尿道感染157例，医院获得性泌尿道感染率为0.66%；导尿管使用率为80.83%，导尿管相关泌尿道感染发病率为1.25‰。共检出菌株162株，其中真菌66株，占40.74%；革兰阴性(G-)菌51株，占31.48 %；革兰阳性(G+)菌45株，占27.78%。 结论ICU医院获得性泌尿道感染病原菌以真菌为主，医院应尽早采取综合干预措施，控制ICU医院获得性泌尿道感染。

Abstract:

ObjectiveTo understand healthcareassociated urinary tract infection (HAUTI) and pathogens causing HAUTI in intensive care unit (ICU) patients, so as to provide scientific basis for the prevention and control of HAUTI. MethodsTargeted surveillance data about HAUTI  in 32 hospitals in 2013 were analyzed. ResultsA total of  23 680 ICU patients were monitored, 157 cases of HAUTI occurred,  HAUTI rate was 0.66%; the usage rate of urinary tract catheter was 80.83%，catheterassociated UTI was 1.25‰.  A total of 162 pathogenic strains were detected, the percentage of fungi, gramnegative bacteria, and grampositive bacteria was 40.74% (n=66)； 31.48 % (n=51), and 27.78% (n=45) respectively. ConclusionThe main pathogens causing HAIURI are fungi, comprehensive intervention measures should be taken to control HAUTI in ICU patients.
