498例死亡病例院内感染情况调查分析

本文调查我院1986～1989年住院死亡病例498例,发生院内感染者91例,感染率18.27％。其中直接死亡率3.3％,间接死亡率25.3％。感染构成比以呼吸系统、肿瘤疾病较多,感染率以胶原结缔组织疾病最高。感染部位以下呼吸道最常见、感染细胞以革兰氏阴性杆菌为多。外科死亡病例院内感染机会相对较少,但后果较严重。住院时间越长,感染机会越多。今后必需加强对危重病人院内感染的预防和监测。

A Survey on the Nosocomial Infection in 498 Cases of Death in Hospitalization

A survey made on 498 cases of death in hospitalization for the nosocoimal infection rate is reported. Among 498 cases of death, 91 cases of nosocomial infection were found, counting for an in- fection rate of 18.27%. The direct and indirect fatal- ity rate are 3.3% and 25.3% respectively. In all cases of infection, those suffering from respiratory system diseases and tumor were found to be the top two in number of infection and collagenic connective tisseu diseases of the highest in term of infection rate. The most commonly seen infection site was observed as the lower respiratory tract and the most commonly seen bacteria responsible for infection was found to be Gram-negtive baccilus. For those died of surgical diseases, the infectien incidence appeared to be smal- ler, but once infected, the effect is much more seri- ous. It is suggested that the risk for infection grow with the time length of the hospitalization.
