2001年我院医院感染现况流行病学调查及分析

目的：为进一步研究医院感染发生规律及发生的危险因素。以降低医院感染发生率。方法；对我院2001年6月27日住院的695例患进行医院感染及其危险因素的横断面调查研究。结果：医院感染发生率为7.91%，其中下呼吸道感染占32.72%。上呼吸道感染占27.27%，泌尿道感染占10.91%，气管切开，使用呼吸机，动静脉置管，泌尿道插管为医院感染的高危因素。医院感染的主要病原体依次为金黄色葡萄球菌，铜绿假单胞菌；合并真菌感染8例，术后预防性使用抗生素的比例偏高。结论：对存在上述危险因素的患应加强监测。重视无菌操作技术，加强对抗生素的合理应用及管理，用于预防应严格控制。

The 2001 Clinical Epidemiologic Survey on Nosocomial Infection in Our Hospital

Objective:To control the nosocomial infection (NI) incidence and survey the NI risk factors and epidemiologic profiles. Methods:The data of 659 in-patients has been analyzed by field survey in our hospital in June 27,2001.Results:NI incidence of our hospital was 7.91%,including 32.72% of lower respiratory duct infection,27.27% of upper respiratory duct infection,and 10.91% of urinary tract infection. The result showed that the germs mainly were staphylococcus aureus and Pseudomonas aeruginosa.Urinary intubation,A-V intubation,tracheotomy and assisted ventilation were the risk factors of NI.Eight cases were complicated with fungus infection.The clinical use of preventive antibiotics in operation departments was relatively usual. Conclusions:We are to enhance our survey on those patients with risk factors of NI and attach important to aseptic techniques.It is particularly necessary to emphasize the proper medication with antibiotics and limit the overuse of preventive antibiotic therapy.
