摘要
目的探讨医院感染的临床特点,了解其易感人群、易感部位、常见病原菌及危险因素,为有效预防与控制医院感染提供理论依据。方法利用回顾性调查的方法,对医院2009年17 108例住院患者进行统计分析。结果医院感染603例,医院感染率3.52%;医院感染发生率最高的科室为重症监护病房占17.74%,最常见部位为下呼吸道219例占36.32%;最常见的危险因素为慢性基础疾病、放化疗、侵入性诊疗操作;医院感染的主要病原菌依次是铜绿假单胞菌、肺炎克雷伯菌、金黄色葡萄球菌和大肠埃希菌。结论有效预防和控制医院感染应积极治疗原发病,对重点科室定期监测,尽量减少侵入性操作,及时做病原菌和药敏检测,合理应用抗菌药物。
OBJECTIVE To discuss the characteristics of nosocomial infection,acquaintance the sensitive population,sensitive site,common pathogenic bacteria and risk factors,supply theoretical basis for the prevent and control measures of nosocomial infection.METHODS A total of 17108 patients diagnosed nosocomial infection from Jan to Dec 2009 were investigated by retrospective analysis.RESULTS Totally 603 cases-times nosocomial infections（nosocomial infection rate was 3.52%） were incestigated;The highest incidence of nosocomial infection was intensive care unit（17.74%）;the sensitive site was the lower respiratory tract（36.32%）;the most common risk factors were chronic diseases,radiotherapy and chemotherapy,invasive medical operations;the main pathogenic bacteria were Pseudomonas aeruginosa,Klebsiella pneumoniae,Staphylococcus aureus,E.coli.CONCLUSION Active cure the primary affection,regular monitoring key section offices,decreasing invasive medical operations,increasing rate of pathogenic bacteria detection can prevent and control measures of nosocomial infection.
