呼吸内科病人院内感染的临床分析

Clinical analysis of nosocomial infection in department of respiratory diseases

目的:研究呼吸内科病人院内感染的临床特征。方法:选取我院2011年5月至2015年5月1263例住院病人为研究对象,对病例资料进行回顾性分析,确定院内感染的诊断。经统计分析,比较感染组和非感染组的病例资料在性别、住院时间、有创操作以及病原学各方面的差异性。结果:1263例呼吸内科住院病人发生院内感染121例,院内感染发生率为9.58%。呼吸内科院内感染的部位以呼吸系统为主,其构成比为59.5%(72例)。感染组与未感染组的年龄,住院时间和有创操作比较有显著性差别(P<0.05)。121例院内感染病人共检出病原菌187株。其中革兰氏阳性菌均占22.31%,革兰氏阴性菌占77.69%。结论:呼吸内科患者院内感染发生率较高。年龄、住院时间和有创操作为院内感染的危险因素。

Objective： To study the clinical characters of nosocomial infection in department of respiratory diseases. Methods： One thousand and two hundred sixty-three patients in department of respiratory diseases from May, 2011 to May, 2015 were involved in the present study. The nosomial infection was determined with the clinical data. The clinical data including genders, length of stay, invasive operation and pathogens were analyzed. Results： There were 121 cases with nosocomial infection of the 1263 patients in de- partment of respiratory diseases. The rate of nosocomial infection was 9.58%. The primary infectious position was respiratory system （59.5%）. The age, length of stay and invasive operation of infectious group and non-infectious group were different （P〈0.05）. There were 187 strains pathogens detected including 22.32 % Gram-positive bacterium and 77.69% Gram-negative bacterium. Conclu- sion： There is high rate of nosocomial infection in department of respiratory diseases. The age, length of stay and invasive operation is the risk factors of nosocomial infection.
