医院感染现患率调查研究进展

Research Progresses on Prevalence Rate of Nosocomial Infection

医院感染现患率调查是医院感染监测的重要手段,能够快速获得某一时点或时段所有住院患者的医院感染发病情况和危险因素分布,帮助监测医院感染发病趋势和评价感染控制效果。相较发病率调查,现患率调查具有简单、快速及相对价廉的优点,已成为医院感染监测的主要手段。随着医疗水平不断提高,医院感染会日趋复杂,在现今信息技术迅速发展的时代,现患率调查也显现出一些不足。本文就医院感染现患率调查的研究进展进行简要综述,以期了解医院感染现患率调查现状,并据此探讨现患率调查的改进。

As an important method of nosocomial infection surveillance, prevalence survey can help monitor prevalence trends and evaluate the infection control results of nosocomial infection by obtaining hospital infection incidence and risk factors distribution from inpatients quickly at a certain point or time. Compared with incidence survey, prevalence survey is simple, rapid and relatively low-priced, and has become the primary method of nosocomial infection surveillance. Along with the continuous improvement of medical treatment level, nosocomial infection will become increasingly complicated. And the prevalence survey has also showed some weaknesses in the era of rapid development of information technology. In order to understand the status of prevalence survey, the paper brief reviews of research advances in prevalence survey, and thus exploring the improvements of prevalence survey.
