老年患者院内泌尿系感染临床特点分析

目的：分析研究老年患者院内泌尿系感染的临床特点。方法：选取2011年12月-2013年2月在本院进行治疗的240例老年患者为研究对象,将其中的院内泌尿系感染发生率进行分析,并将其中不同性别、年龄段、伴发基础疾病、是否存在其他感染灶、是否进行侵入性操作者的感染发生率进行比较,另外将病原菌分布情况进行分析。结果：240例老年患者中共有21例发生院内泌尿系感染,发生率为8.75%,女性、≥70岁者、伴发基础疾病≥2种、存在其他感染灶及进行侵入性操作者的感染发生率均高于其他患者,而病原菌中以大肠埃希菌所占比例最高,明显高于其他菌种,差异均有统计学意义（P〈0.05）。结论：老年患者院内泌尿系感染的危险因素较多,且以大肠埃希菌检出率最高。

Analysis of the Clinical Characteristics of Urinary Tract Nosocomial Infection in Aged Patients

Objective：To analyze and study the clinical characteristics of nosocomial urinary tract infection of elderly patients.Method：240 elderly patients in our hospital from December 2011 to February 2013 were selected as research object,and the urinary tract infection rate of all the patients was analyzed,the infection rate of patients with different gender,ages,basic disease,with or without other infection and invasive operation were compared,then the pathogenic bacteria distribution were analyzed.Result：21 cases of 240 elderly patients were with nosocomial urinary tract infection,the rate was 8.75%,the infection rate of patients with female,≥70 years old,basic disease≥2 kinds,other infection and invasive operation were higher than those of other patients,and the rate of escherichia coli in all pathogenic bacteria was the highest,and it was obviously higher than those of other pathogenic bacteria,there were all significant differences（P〈0.05）.Conclusion：The more risk factors of nosocomial urinary tract infection in elderly patients,and the detection rate of escherichia coli is highest.
