目的 :报告成都市 1996年医院感染调查分析结果。方法 :回顾性调查。结果 :72 86 7例住院病人中感染病例430例 ,平均医院感染率 10 .45 % ,其中综合医院为 12 .35 % ,专科医院为 7.6 5 % ,两者有显著性差异。感染病例与住院天数有关 ,感染病人平均住院 44天 ,高于非感染病人 (15天 ) ;感染科室与部位分布以儿科及下呼吸道为高。院感平均死亡率显著高于住院病人总死亡率。感染病原体顺位分别为细菌、真菌、病毒 ;经单因素分析筛选出年龄、住院天数、免疫抑制等 8个有显著意义的危险因素。结果 :本文所得结果与全国医院感染调查基本一致 ,并提示在控制本市医院感染方面应加强医技知识行为和消毒隔离等方面的措施干预 ,以降低院感发病率 Objective: To report the results of a survey on hospital infection in Chengdu in 1996. Methods: Retrospective investigation. Results: Of the 72 867 inpatients with 430 cases, the average hospital infection rate was 10.45%, of which 12.35% were in general hospitals and 7.65% in special hospitals. There were significant differences between the two. Infected cases and hospitalization days, the average patient hospitalized 44 days, higher than non-infected patients (15 days); infection departments and parts of the pediatric and lower respiratory tract distribution is high. The average hospital mortality rate was significantly higher than the total hospital mortality. The sequence of infectious pathogens were bacteria, fungi and viruses respectively. There were 8 significant risk factors such as age, length of hospital stay, immunosuppression and so on, screened by univariate analysis. Results: The results obtained in this paper are basically consistent with the national survey of nosocomial infections and suggest that interventions should be stepped up in the control of nosocomial infections in the city in order to reduce the incidence of nosocomial infections
