某院连续2年医院感染现患率调查分析

Two one-day point prevalence surveys on healthcare-associated infection in a hospital

目的了解某院医院感染现患率,评价医院感染日常监测资料的可靠性和准确性。方法根据2008年全国医院感染监控网横断面调查要求,采取横断面调查方法,对调查日0∶00—24∶00的所有住院患者进行医院感染现患率调查,填写统一的个案调查表,并对调查资料进行统计分析。结果 2010年6月9日和2011年4月8日两次共调查住院患者1 196例,实查率分别为97.04%和97.58%;医院感染现患率分别为6.27%和6.11%,略高于当月医院感染发病率(5.01%、5.54%)。医院感染部位以下呼吸道(66.27%)为主,其次是泌尿道(13.25%)和上呼吸道(7.23%)等。结论开展医院感染现患率调查有利于了解医院感染现状和提高日常监测工作质量,并针对医院感染率较高的科室进行重点监测及干预,采取有效措施降低医院感染率。

Objective To investigate the prevalence rate of healthcare-associated infection（HAI） in a hospital,and evaluate the reliability and accuracy of routine HAI surveillance data.Methods HAI prevalence rate survey was conducted among all inpatients from 0∶00 to 24∶00 on investigation day with cross-sectional survey,uniform questionnaires were filled out,and data were analyzed.Results On June 9,2010 and April 8,2011,1 196 inpatients were investigated,the actual investigation rate was 97.04% and 97.58% respectively;HAI prevalence rate was 6.27% and 6.11% respectively,which was slightly higher than HAI of the respective month（5.01% and 5.54% respectively）.The main infection site was lower respiratory tract（66.27%）,followed by urinary tract（13.25%） and upper respiratory tract（7.23%）.Conclusion Prevalence survey can benefit to realize the current status of HAI,improve routine surveillance quality,and take proper measures to reduce HAI rate through the intervention in departments with high HAI.
