医源性伤害中医院感染的流行病学调查

Hospital Infection in Iatrogenic Injury:An Epidemiological Analysis

目的探讨医源性伤害中医院感染发生特征、发展趋势及其影响因素。方法对2000年1月-2007年12月某院收治的750例医院源性伤害患者的医院感染进行回顾性调查。结果医源性伤害中医院感染的发生率为33.2%;医院感染部位分布以手术部位医院感染最多见,占87.39%,其次为深部体腔感染占8.98%;医源性伤害感染病原菌中革兰阴性杆菌占57.11%。结论对于医源性伤害的医院感染控制,应尽早纳入公共卫生防控范畴,促进医疗卫生质量提高,保障患者的生命健康和安全。

OBJECTIVE To explore the features, developing trend and factors of hospital infection in patients with iatrogenic injury. METHODS Retrospective surveys of hospital infections in 750 cases with iatrogenic injury were carried out in hospital between 2000 and 2007. RESULTS The incidence of hospital infection in patients with iatrogenic injury was 87.39%. Among them, hospital wound infection was the highest （87.39%）,the second one was cavity infection （ 8. 98%）. The leading causative microorganisms were Gram-negative bacteria. CONCLUSIONS It is imperative to make effort to decvease the morbidity of hospital infections. We hope that the iatrogenic injury can be brought into the category of public health as soon as possible to enhance the medical care service and secure salty and health of the patients.
