36120例住院患者医院感染调查分析

Nosocomial Infections in 36120 Inpatients

目的了解医院感染现状,为提高医院感染管理水平提供科学依据,降低医院感染发生率。方法对2006-2007年各季度医院感染监测资料进行回顾性分析。结果医院感染发生率、感染例次率分别为4.66%、5.97%;医院感染发生部位以下呼吸道为最高,其次为泌尿道;危险因素以留置深静脉导管、留置导尿管、使用呼吸机为最多;对出院的医院感染病例和非医院感染病例进行比较,年龄、住院天数、死亡率、医疗费用差异均有统计学意义。结论预防深静脉导管、留置导尿管、呼吸机管道感染、保护易感宿主、开展前瞻性医院感染监测,是预防医院感染的有效措施。

OBJECTIVE To investigate the status of nosocomia infection and provide scientific reference for nosocomial infection control. METHODS Retrospective analysis based on the nosocomial infection materials of January, April, July, October,from 2006 to 2007 were conducted. RESULTS Both the infection incidence and the infection ratio were 4.66% and 5.97%, The main infection sites were lower respiratory tract, urinary tract and gastrointestinal tract. The risk factors were central venous catheters, urine catheters and mechanical ventilation. The nosocomial infection cases were compared with non-nosocomial infection control cases in age,number of days in hospital, death rate and medical treatment fee. There were significant difference between them. CONCLUSIONS It is an efficiency step in preventing infection from central venous catheters, urine cathters and mechanical ventilation,protecting sensitized hosts and developing the prospective analysis of nosocomial infection monitoring.
