医院内获得性肺炎危险因素病例对照研究

A Matched Case-Controlled Study of Risk Factors of Nosocomial Pneumonia Caused by Tumor

目的 探讨医院内获得性肺炎危险因素。方法 对 77例肿瘤患者院内获得性肺炎的危险因素进行 1:1病例对照研究。结果 肿瘤患者院内获得性肺炎 (NP)感染病死率为 14 3 %。发生医院感染危险因素为免疫抑制治疗、手术、住院时间、抗生素应用时间、呼吸道插管。结论 肿瘤患者院内获得性肺炎的发生是多因素综合作用的结果 ,应引起临床重视 。

Objective To study some risk factors of acquired nosocomial pneumonia in tumor case nosocomial infection.Methods 77 tumor case with nosocomial infection were chosen as cases from the patients in hospital for 1:1 case control study.Results It was found that the fatality rate of acquired NP in tumor pattens was 14 3%.Some risk factors of acquired nosocomial infection in tumor case remained significant through logistic regression analysis showed,such as state of an immunosuppression therapy; operation,hospitalization duration,antibiotics application time and mechanical ventilation.Conclusions It was suggested that the iatrogenic pneumonia is comes from multiple risk factors and it should be paid attention. This is the most important step to control nosocomial infection of tumor case in the hospital happen.
