目的调查医院感染现状及抗菌药物使用情况,分析院感高危因素。方法 2012年8月采用病例调查与床旁调查相结合的方法,对在院患者进行调查,统计数据并分析研究。结果本次实查1 309人,现患率为2.9%,感染例次率为3.3%。抗生素使用率为41.5%,治疗性用药病原微生物送检率为40.9%。多因素分析显示:高龄、进行动静脉插管操作及手术是高危因素。结论加强对高危因素、高风险科室、易感人群的监测及管理,提高病原菌送检率,合理使用抗菌药物,是控制医院感染发生的必要措施。
Objective To investigate the current status of nosocomial infection and the use of antibacterials and to analyze the risk factors of nosocomial infection. Methods In August 2012, a combination of case and bedside surveys was used to investigate the patients in hospital and analyze the data. Results This survey of 1 309 people, the prevalence rate of 2.9%, the infection rate was 3.3%. The antibiotic use rate was 41.5%, and the therapeutic drug pathogenic microorganism delivery rate was 40.9%. Multivariate analysis showed that: elderly, arteriovenous catheterization and surgery are risk factors. Conclusion To strengthen the monitoring and management of high-risk factors, high-risk departments and susceptible populations, improve the rate of pathogenic bacteria and rational use of antimicrobial agents are necessary measures to control nosocomial infections.
