626例医院感染病例调查分析

Nosocomial Infection: Investigation on 626 Cases

目的了解、掌握医院感染现状,为降低医院感染率提供依据。方法回顾性调查2004年10月-2005年9月住院患者40 554例,医院感染626例。结果2005年医院感染率为1.54%,医院易感人群中以老年患者居多,住院时间越长,发生医院感染的危险性越大,高危感染科室为老年监护室和血液科,感染高发部位为呼吸道,医院感染病种以恶性肿瘤居多,侵入性诊疗技术操作是引起医院感染的因素之一。结论医院感染率偏低,建立医院感染管理监控系统,利用先进统计软件进行辅助监控,从统计规律性的角度发现感染缺陷。

OBJECTIVE To investigate the present situation of the nosocomial infection in our hospital in order to decrease the infection rate. METHODS A total of 40 554 patients were inspected from Oct 2004 to Sept 2005. There were 626 patients with nosocomial infection. RESULTS The nosocomial infection was 1.54%. Old patients were the main components. The longer they were in hosptial,the more risk of infection they had. Elder monitoring department and hematological department were the most common infected units. Respiratory tract was the most common infected site of the body. The entity of disease for the most infection was malignant tumor. Invasive treatment was one of the causes for the infection. CONCLUSIONS The infection rate of our hospital was relatively low. We should establish the system to control the infection. Use the advanced statistical software well be to aid the control and discover the anti-infection deficiency from the statistical view-point.
