【摘要】：目的探讨门诊老年患者呼吸道感染的病原菌类型及耐药性,分析呼吸道感染相关危险因素,为降低门诊老年患者呼吸道感染提供参考依据。方法回顾性分析医院2012年1月-2014年12月650例老年患者的临床资料,分析其感染病原菌类型、主要病原菌耐药性,并对呼吸道感染危险因素进行单因素和多因素方差分析,采用SPSS19.0软件对数据进行统计分析。结果 650例门诊老年患者发生呼吸道感染30例,感染率为4.62%,共检出病原菌42株,其中革兰阳性菌28株占66.67%,革兰阴性菌13株占30.95%,真菌1株占2.38%;革兰阴性菌以大肠埃希菌及铜绿假单胞菌为主,对亚胺培南、万古霉素耐药率较低,革兰阳性菌以表皮葡萄球菌及金黄色葡萄球菌为主,对万古霉素的耐药率较低;经单因素和logistic回归分析发现,年龄70岁、未服保健品、合并糖尿病等因素是老年患者发生呼吸道感染的独立危险因素(P0.05)。结论门诊老年患者呼吸道感染相关危险因素较多,应针对危险因素采取相应的措施进行干预。
[Abstract]:Objective to investigate the types of pathogens and drug resistance of respiratory tract infection in elderly outpatients, and to analyze the risk factors of respiratory tract infection in order to provide reference for reducing respiratory tract infection in elderly outpatients. Methods the clinical data of 650 elderly patients from January 2012 to December 2014 were analyzed retrospectively. The types of pathogenic bacteria, the main pathogens resistance and the risk factors of respiratory tract infection were analyzed by univariate and multivariate analysis of variance. The data were analyzed by SPSS 19.0 software. Results there were 30 cases of respiratory tract infection in 650 outpatients, the infection rate was 4.62%, 42 strains of pathogenic bacteria were detected. Among them, 28 strains of Gram-positive bacteria accounted for 66.67%, 13 strains of Gram-negative bacteria accounted for 30.95%, and one strain of fungi accounted for 2.38%, Gram-negative bacteria were mainly Escherichia coli and Pseudomonas aeruginosa, and the resistance rate to imipenem and vancomycin was low. Gram-positive bacteria were mainly Staphylococcus epidermidis and Staphylococcus aureus with low resistance to vancomycin. Univariate and logistic regression analysis showed that the age of 70 years old was not treated with health products. Diabetes mellitus and other factors were independent risk factors of respiratory tract infection in elderly patients (P0.05). Conclusion there are many risk factors related to respiratory tract infection in elderly outpatients.
