我院1986年8～10月院内感染率为9.06％,院内感染高危区为泌尿外科、血液病科、神经内科、神经外科、儿科。住院病人发生院内感染时的住院天数P_(95)=3.5天。院内感染病原体以绿脓杆菌多见,其耐药情况较社会感染病原体严重。住院病人抵抗力降低或具有感染倾向及各种诊疗操作手段等是院内感染的危险因素。
In our hospital from August to October 1986, the nosocomial infection rate was 9.06%. The high-risk nosocomial infections were urology, hematology, neurology, neurosurgery and pediatrics. Inpatients hospitalized with nosocomial infection days P_ (95) = 3.5 days. Nosocomial infection with Pseudomonas aeruginosa more common, its resistance to pathogens more serious than the community. Inpatients with reduced immunity or have a tendency to infection and various means of diagnosis and treatment of nosocomial infections are risk factors.
