Investigation and analysis on prevalence rate of nosocomial infection in Shenyang Cityfrom 2010 to 2012

目的了解沈阳市某医院医院感染发生情况和趋势，为针对性地预防医院感染提供依据。方法采用横断面调查的方法，于2010-2012年对该院某日0-24时所有住院患者进行调查。结果该院3年医院感染现患率为4．59％-6．05％，显著高于当月医院感染发病率（1．50％-2．10％）。医院感染感染部位以呼吸道为主，其次为泌尿道等。抗菌药物使用率为51．63％-58．91％，治疗性使用抗菌药物病原学送检率为20．37％-23．07％。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。同时应加强重点部门、重点部位的目标性监测与管理，加强抗菌药物的监控与管理，提高病原学送检率，正确、合理地使用抗菌药物。

[ Objective ] To understand the prevalence rate and trends of nosocomial infection （ NI ） in a hospital of Shenyang City, so as to provide the basis for targeted prevention of NI. [ Methods] The cross-sectional survey was adopted to investigate all inpatients in a hospital at one day in three consecutive years（ from 2010 to 2012 ）. [ Results] The prevalence rate of NI was 4.59% - 6.05% in three consecutive years, which was obviously higher than NI of that month（ 1.50% - 2.10% ）. The main infection site was respir- atory tract, followed by urinary tract. The usage rate of antimicrobial agents was 51.63%-58.91%, sample detection rate was 20. 37%- 23.07%. [ Conclusion] Prevalence survey is beneficial to realize the current status of NI, and improve routine surveil- lance quality. Targeted surveillance and management of key department and key sites should be strengthened, the monitoring and management of antimicrobial agents should be stressed, detection rate of samples should be improved, and antimicrobial agents should be used correctly and rationally.
