医院获得性肺炎发生原因分析

Cause analysis of hospital acquired pneumonia

目的：探讨医院获得性肺炎发生的诱因。方法：回顾性分析2012年9月~2015年9月我院 ICU 收治的418例获得性肺炎的临床资料。对病例采用单因素分析和多因素 Logistic 回归分析，对可能与医院获得性肺炎的相关的危险因素进行筛选。结果：418例获得性肺炎患者中，发生医院获得性肺炎的患者有45例。医院获得性肺炎的相关因素有年龄、意识状态、原有慢性肺部基础病、气管切开、纤支镜检查、机械通气、吸痰、吸氧、住院时间以及抗生素的使用时间等，对以上因素进行 Logistic 多元分析，年龄、意识状态、原有慢性肺部基础病、气管切开以及抗生素的使用时间均为发生院内获得性肺炎的危险因素。结论：医院获得性肺炎的独立危险因素包括年龄、意识状态、原有慢性肺部基础病、气管切开以及抗生素的使用时间等。对这些独立危险因素进行严格有效地把控，极大程度地降低医院内获得性肺炎的发生。

Objective：To explore the causes of hospital acquired pneumonia. Methods：Retrospectively analyzed the clinical information of 418 acquired pneumonia patients admitted in ICU of our hospital from September 2012 to September 2015. Screened relevant risk factors of hospital acquired pneumonia with univariate analysis and multivariate analysis. Results：Among the 418 acquired pneumonia patients,there were 45 hospital acquired pneumonia pa-tients. The relevant factors of hospital acquired pneumonia were age,ideology,original chronic lung basic disease,tracheotomy,fiberoptic bronchoscopy, mechanical ventilation,sputum suction,oxygen uptake,hospital stays and time of antibiotic usage,conducted Logistic multivariate analysis on the above factors ,and age,ideology,original chronic lung basic disease,tracheotomy,time of antibiotic usage were all risk factors of hospital acquired pneumonia oc-curence. Conclusion：The independent risk factors of hospital acquired pneumonia contain age,ideology,original chronic lung basic disease,tracheotomy and time of antibiotic usage and so on. Strictly and effectively controlling these risk factors can reduce the occurrence of hospital acquired pneumonia to a remarkable extent.
