医院感染中日常监测与现患率调查研究结果分析

Daily monitoring and prevalence rate of nosocomial infection

目的探讨医院感染的现患率与日常检测情况，分析医院感染的相关因素，即监测系统的效果。方法统计既往两年我院日常检测到的医院感染病例，与2012年4月29日我院医院感染现患率的调查结果进行比较分析。结果医院感染的现患率调查中，感染的人次率和例次率较日常监测值高，感染部位以上呼吸道、下呼吸道、泌尿道和皮肤软组织所占比例最高，但排序略有差异；现患率调查中标本送检率高于日常监测。结论作为评价医院感染监测系统，现患率调查较真实可靠。

Objective To investigate the prevalence rate of nosocomial infection and daily inspection, and to analyze the related factors for hospital-acquired infections or the effect of the monitoring system. Methods The cases of hospital-acquired infections detected in the past two years were reviewed, and then were compared with the survey results of the prevalence rate until April 29,2012. Results In the survey of prevalence rate for nosocomial infection, the rates of number and cases were higher than the values of daily monitoring. The upper and lower respiratory tract, urinary tract, and skin soft tissue were the most common sites for nosocomial infections, with a slight difference in order. The rate of specimen detection was higher in the prevalence survey than in the routine monitoring. Conclusions Prevalence survey is more reliable as a tool for assessing the monitoring system for nosocomial infection.
