摘　　要：目的分析医院感染信息化监测系统在多药耐药菌(MDROs)感染防控中的作用。方法选取广东药科大学附属第一医院作为研究医院,该医院自2020年1月开始采用医院感染信息化监测系统,将2020年1-12月作为研究期,将2019年1-12月作为对照期,对这两个时期内该医院的医院感染情况及MDROs感染情况进行回顾性对比分析。结果在研究期内该医院的医院感染发生率和医院感染病例漏报率分别为2.52%(1325/52624)和1.74%(23/1325),呼吸机相关性肺炎感染(VAP)、导管相关性血流感染(CRBSI)、导尿管相关性尿路感染(CAUTI)的发生率分别为4.10‰(31/7568)、2.11‰(14/6634)、2.50‰(25/9993)均低于对照期(P<0.05);在研究期内病原学检查阳性率为77.95%(1269/1628)高于对照期(P<0.05),整体MDROs检出率为15.77%(206/1306),大肠埃希菌、鲍氏不动杆菌、肺炎克雷伯菌、表皮葡萄球菌、铜绿假单胞菌、金黄色葡萄球菌的MDROs检出率均低于对照期(P<0.05)。结论利用信息化技术开发并应用医院感染监测系统,能有效降低医院感染发生率和器械相关性感染发生率,减少感染病例漏报,还可降低MDROs检出率,减少常见致病菌种中MDROs的检出比例。OBJECTIVE To analyze the role of nosocomial infection informatics surveillance system in the prevention and control of multidrug-resistant organisms(MDROs)infections.METHODS The First Affiliated Hospital of Guangdong Pharmaceutical University was selected as the study subjects,which had adopted the nosocomial infection informatics surveillance system since Jan.2020.The period of Jan.to Dec.2020 were regarded as the study period,and Jan.to Dec.2019 were regarded as the control period.The situation of nosocomial infection and MDROs infections in the two periods were retrospectively analyzed.RESULTS The incidence of nosocomial infections and underreporting of nosocomial infection cases in this hospital during the study period were 2.52%(1325/52624)and 1.74%(23/1325),respectively,and the incidences of ventilator associated pneumonia(VAP),catheter related bloodstream infection(CRBSI),catheter related urinary tract infection(CAUTI)were 4.10%(31/7568),2.11%(14/6634),and 2.50%(25/9993)respectively,which were lower than those during the control period(P<0.05).The positive rate of pathogenic examination in the hospital during the study period was 77.95%(1269/1628),which was higher than that during the control period(P<0.05),the overall detection rate of MDROs was 15.77%(206/1306),the detection rates of MDROs in Escherichia coli,Acinetobacter baumannii,Klebsiella pneumoniae,Staphylococcus epidermidis,Pseudomonas aeruginosa and Staphylococcus aureus were lower than those during the control period(P<0.05).CONCLUSION The development and application of the informatics technology-based surveillance system of nosocomial infection could effectively reduce the incidence of nosocomial infections and device related infections,decrease the under-reporting of infection cases,and also reduce the detection rate of MDROs as well as the proportion of MDROs detected in common pathogenic species.
