武汉市某医院内科医院感染危险因素病例对照研究

STUDY ON THE RISK FACTORS IN THE INTERNALMEDICINE INFECTION OF A HOSPITAL INWUHAN CITY WITH THE CARE-CONTROL

目的:探讨大型综合医院内科住院患者医院感染的一般规律,寻找主要危险因素,为制订具体的医院感染控制措施提供必要的理论依据。方法;选取2000年武汉市某院内科医院感染监测病历,病例经核实后按配对条件1:1配对,采用回顾性调查方法,统计分析采用logistic回归分析方法。结果:病例组分布排序为血液内科(39.2%),心血管内科(20.8%),内分泌科(2.4%);原发病排序为血液病(29.6%),慢性病例(慢性肝炎、肝硬化等)(23.2%),心脑血管疾病(14.4%),恶性肿瘤(8.8%)。单因素分析示:住院天数、慢性肝病、介入性治疗、使用激素。使用免疫制剂、抗生素等6种因素与医院感染相关。结论:介入治疗、使用激素、长期大量使用抗生素等3种危险因素与医院感染有显著性联系,是防治医院感染的重点。

VE:To discover the genal regularity of the hospital infection of the internal (physical) patients in the large hospital,seeking the major risk factors,providing the necessary abstract foundation for particular controling measures in the hospital. METHOD: The verified cases were observated with retrospective study and statistic logistic regression analysis, selecting from the physical infection of a hospital in 2000 years. RESULTS: The ordered case group were hema internal medicine (39.2%), cardiovascular internal medicine(20.8% ) .endocrine medicine(2.4% ) , original disease order was herma-disease(29.6%), chromic disease( chronic hepatiria, hepatocirrhasis,etc)(23.2%) cardiovascular disease (14.4%), malignancy (8.8%). Signle factor analysis indicates:there were six factors relating with the infection of hospitals, which were the days in hospital,chronie liver disease, internal therapy,hormone,immune preparation,antibiotics and so on. CONCLUSION:They were three risk factors which were the days in hospital,hormmone and antibiotics used long-ti;me and quantity,relating remarkably with the infection of hospitals,it was the em-phasis kof prevention the infection in hospital.
