2种医院感染现患率调查方法调查结果分析

Analysis of the survey results of two methods for nosocomial infection prevalence survey

目的比较传统人工调查和信息化调查2种医院感染现患率调查方法的调查结果,为进一步改进现患率调查方法提供参考依据。方法选取某院2018年11月28日所有住院患者为研究对象,比较2种医院感染现患率调查方法的调查结果,确定更佳的现患率调查方法。结果此次调查住院患者2239例,所得医院感染现患率分别为3.22%和2.90%。传统人工调查和信息化调查所得结果基本一致。信息化调查的特异度、总符合率、阳性预测值和阳性似然比均高于传统人工调查。结论现患率调查以信息化调查为主,通过人工调查进行质控,有利于进一步提高医院感染监测水平。

Objective To compare the survey results of two methods of nosocomial infection prevalence survey,and to provide a reference for further improving the prevalence survey method.Methods All hospitalized patients in a hospital on November 28,2018 were selected as the research subjects,and the results of two methods for nosocomial infection prevalence survey were compared to determine a better prevalence survey method.Results This survey included 2239 hospitalized patients.The prevalence rates of nosocomial infection obtained from traditional manual survey and informationbased survey were 3.22%and 2.90%,respectively.The results obtained by traditional manual survey and information-based survey were basically the same.The specificity,total coincidence rate,positive predictive value,and positive likelihood ratio of information-based survey were all higher than those of traditional manual survey.Conclusion The prevalence survey is mainly based on information-based survey,and the quality control through manual survey is helpful to further improve the level of hospital infection surveillance.
