慢性阻塞性肺疾病患者医院感染的特征及危险因素分析

Analysis on Characteristics and Risk Factors of Nosocomial Infections in Patients with COPD

目的:分析降低慢性阻塞性肺疾病(COPD)医院感染的发生率,研究和探讨医院感染的特征以及危险因素。方法:按照随机原则选取2015年1月—2016年1月间收治的COPD患者50例临床资料,采用Logistic回归分析方法统计患者的住院资料及其危险因素。结果:经过统计发现,入组患者中发现了45例病原菌,其中以大肠埃希菌所占比例最高66.67%,其次为肺炎克雷伯菌、粪肠球菌和变形菌属的发生率分别为6.67%,6.67%和4.447%;用Logistic回归分析发现,高龄、长时间住院、伴有其他慢性疾病、放置导管、化放疗和抗菌药物大量使用的患者为医院感染的危险因素。结论:COPD患者具有较高的医院感染发生率,而且诱发因素很多,医务人员必须时刻警惕常见的危险因素,以减少COPD医院感染的发生率。

Objective： To analyze the characteristics and risk factors of thc nosocomial infection, and to reduce the incidence rate of pulmonary infection in chronic obstructive pulmonary disease（COPD）. Methods： 50 patients with COPD, who were admitted in our hospital during January 2015 and January 2016. were selected as the research object. Regression analysis was used to analyze the data of hospitalized patients, and the risk factors were analyzed by Logistic regression analysis. Results： Statistics found that patients with a total of 45 cases of pathogenic bacteria, including Escherichia coli accounted for the highest proportion of 66.67%, followed by tbe pneumonia gram Reber fungus, Enterococ- cus faecalis and Proteobacteria species, and the occurrence rate was 6.67%, 6.67% and 4.447%. Logistic regression anal- ysis showed that age, long time hospitalization, suffering other chronic diseases, the catheter, radiotherapy and applica- tion of antibacterial drugs were the risk factors of hospital infection. Conclusion： Patients with COPD have a high inci- dence of nosocomial infection, and a lot of predisposing factors, so medical personnel must always be vigilant of common risk factors, reducing the incidence of chronic lungs disease nosocomial infection.
