神经内科ICU住院患者医院获得性肺炎危险因素的Logistic回归分析

Binary Logistic regression analysis of hospital acquired pneumonia in neurological ICU patients

目的探讨神经内科ICU住院患者获得性肺炎的危险因素,为防治肺炎提供科学依据。方法分析2007-11～2008-10神经内科ICU共194例住院患者,其中并发肺炎患者138例作为病例组,住院同期没有并发肺炎患者56例作为对照组,研究其年龄、性别、住院天数等方面共16个因素,对收集到的资料进行单因素分析与BinaryLogistic回归分析。结果单因素分析发现住院天数、留置胃管、留置尿管、动静脉插管、气管插管或气管切开、有创性机械通气、昏迷与肺炎有关。Logistic回归确定住院天数、留置胃管为获得性肺炎影响因素。结论神经内科ICU住院患者获得性肺炎是外部的医疗环境与患者本身的内环境因素综合作用的结果。

Objective To explore the risk factors of hospital acquired pneumonia in neurological ICU patients, and to provide the corresponding clinical prevention strategies. Methods The clinical data of all the 194 patients admitted to our neurological ICU from November 2007 to October 2008 were retrospectively investigated, of them 138 patients complicated whh pneumonia as the case group, 56 patients without complications of pneumonia as the eontrol group. A total 16 factors, including the age, sex, days of hospital stay ect, were collected for single-factor analysis and Binary Logistic regression analysis. Results The single-factor analysis showed that the number of hospital days, indwelhng stomach tube, indwelling urinary catheter, artery and vein cannulation, tracheal intubation or tracheostomy, invasive mechanical ventilation, and coma were related to acquired pneumonia. Logistic regression determined the number of hospital days, indwelling stomach tube were the risk factors for hospital acquired pneumonia. Conclusion The internal and external environment factors lead to acquired pneumonia of neurological ICU patients.
