医院获得性肺炎危险因素分析

目的探讨医院获得性肺炎(HAP)发生的危险因素。方法将本院2004年1月～2005年7月确诊医院获得性肺炎的120例作观察组,与同期未发生医院获得性肺炎的120例作对照组,作单因素和logisiti回归分析。结果两组患者基础疾病、年龄>60岁,入住ICU、留置导尿>3d、留置胃管>2d、插管机械通气、联合应用2种以上抗生素情况间差别均有显著性意义(P<0.05),其中联合应用2种以上抗生素、入住ICU、留置胃管>2d、插管机械通气,基础疾病是医院获得性肺炎的独立危险因素。结论医院获得性肺炎发生是多因素共同作用的结果,必须针对重点人群、高危因素及相关环节进行防治。

Risk Factors Analysis of Hospital Acquired Pneumonia

Objective To discuss risk factors of pneumonia acquired in hospital.Methods By reviewing 120 patients with hospital acquired pneumonia and 120 patients without hospital acquired pneumonia from the same period,then comparing the two groups and analysing the risk factors of hospital acquired pneumonia used One-Way and Logistic regression analysis.Results The independent risk factors were as follows:the kinds of antibiotics more than three (OR=10.457),the therapy intensive care unit(OR=8.354),the presence of nasogastric intubation (OR=5.314),the use of a cascade humidification system(OR=5.235),underlying disease(OR=2.342).Conclusion Hospital acquired pneumonia related with multiple factors working together,so we should focused on the special group and high risk factor and find prventitive measures.
