摘　　要：目的基于Log(Logistic)回归分析构建医院获得性军团菌(LP)感染的预测模型及防治策略。方法回顾性分析2019年1月至2020年1月本院收治的细菌性肺炎患者资料,根据患者致病菌种将入选患者分为NLP组103例,LP组49例。对比两组临床资料分析LP感染的相关因素,将相关因素代入Log回归分析,明确LP感染的危险因素。结果两组患者性别构成、年龄结构均未见统计学差异(P>0.05);有吸烟史、有中央空调使用史、有人工水循环系统接触史、既往有糖尿病史、免疫功能异常史为医院获得性军团菌肺炎的相关因素(P<0.05);有吸烟史、有中央空调使用史、有人工水循环系统接触史、有糖尿病、有免疫功能异常为医院获得性军团菌肺炎的独立危险因素(OR>1,P<0.05)。结论经Log回归分析有中央空调使用史,有人工水循环系统接触史,合并糖尿病、免疫功能异常,有吸烟史为医院获得性军团菌感染肺炎的危险因素,通过对症干预、阻断军团菌感染原等方法可有效预防医院获得性军团菌感染。Objective To establish a predictive model and prevention strategy for hospital-acquired Legionella(LP)infection based on Log(Logistic)regression analysis.Methods The data of patients with bacterial pneumonia admitted to our hospital from January 2019 to January 2020 were retrospectively analyzed.The patients were divided into NLP group(n=103)and LP group(n=49)according to their pathogenic bacteria species.The clinical data of the two groups were compared to analyze the related factors of LP infection,and the related factors were substituted into Log regression analysis to identify the risk factors of LP infection.Results There was no significant difference in gender composition and age structure between the two groups(P>0.05).History of smoking,use of central air conditioning,exposure to artificial water circulation system,history of diabetes,and history of immune dysfunction were related factors of hospital-acquired Legionella pneumonia(P<0.05).History of smoking,use of central air conditioning,exposure to artificial water circulation system,diabetes,and immune dysfunction were independent risk factors for hospital-acquired Legionella pneumonia(OR>1,P<0.05).Conclusion through the Log regression analysis in hospitalized patients with a history of central air conditioning usage,with the artificial water cycle system exposure history,diabetes mellitus,immune dysfunction,has a history of smoking for hospital acquired legionella pneumonia risk factors,through suit the intervention,blocking legionella infection such as the original method to be effective in preventing hospital acquired infection of legionella.
