目的了解医院感染发病率变化及感染致病菌分布特征,为控制医院感染提供依据。方法通过回顾性调查,对本医院2000-2008年住院患者医院感染发病率以及病原菌变化趋势进行了调查与分析。结果该医院在2000-2008年期间住院患者中共发生医院感染患者6 203例,平均医院感染发生率为2.9%,波动在2.0%～4.1%之间。感染部位以下呼吸道为主,血液感染呈上升趋势。医院感染病原菌以白色念珠菌、大肠埃希菌和铜绿假单胞菌为主,2004年后鲍曼不动杆菌呈上升趋势。结论该医院的院内感染发生率低于国内平均水平,但血液感染呈上升趋势;感染病原菌以真菌和革兰阴性杆菌为主,应以此制定防控措施。
Objective To understand the change of nosocomial infection and the distribution of pathogenic bacteria in infection, so as to provide basis for controlling nosocomial infection. Methods A retrospective survey was conducted to investigate and analyze the prevalence of nosocomial infections and the trend of pathogenic bacteria inpatients from 2000 to 2008 in our hospital. Results A total of 6 203 hospitalized patients were hospitalized in the hospital from 2000 to 2008, with an average hospital infection rate of 2.9% and a fluctuation of 2.0% -4.1%. The main respiratory tract infection, blood infection is on the rise. Nosocomial infections with Candida albicans, Escherichia coli and Pseudomonas aeruginosa dominated the 2004 Acinetobacter baumannii upward trend. Conclusion The incidence of nosocomial infection in this hospital is lower than the national average, but the blood infection is on the rise. The main pathogens of infection are fungi and Gram-negative bacilli, and prevention and control measures should be formulated accordingly.
