目的了解医院感染现患率,评价医院感染日常监测资料的可靠性和准确性,为医院感染预防与控制工作提供科学依据。方法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,并对调查当日处于医院感染的病例进行统计分析。结果 2009年4月21日及11月4日连续两次共调查住院患者1243例,实查率为99.68%;医院感染现患率分别为2.30%和1.86%,医院感染高发科室为神经内科;医院感染部位以上呼吸道为主,其次为下呼吸道和胃肠道。结论针对医院感染发生率较高的科室进行重点监测及干预,加强感染病例标本送检,规范手术科室抗菌药物使用,降低使用率。
Objective To understand the prevalence rate of nosocomial infection and evaluate the reliability and accuracy of nosocomial routine monitoring data to provide a scientific basis for nosocomial infection prevention and control. Methods A cross-sectional survey was conducted to investigate the prevalence of nosocomial infections among all inpatients from 0: 00-24: 00 on the survey day, fill in a single case questionnaire and conduct statistical analysis on the cases of nosocomial infections on the day of the investigation. Results A total of 1,243 in-hospital patients were investigated on April 21 and November 4, 2009 in a row. The actual investigation rate was 99.68%. The prevalence rates of nosocomial infections were 2.30% and 1.86% respectively. The high-incidence nosocomial infection department was neurology. Infections above the respiratory tract, followed by lower respiratory tract and gastrointestinal tract. Conclusions Aiming at monitoring and interveneing the departments with high incidence of nosocomial infection, it is necessary to strengthen the submission of infected specimens and standardize the use of antimicrobial agents in the departments of surgery and reduce the utilization rate.
