我院导管相关尿路感染现状及危险因素分析

Analysis of current situation and risk factors of catheter-related urinary tract infection in our hospital

目的分析我院导管相关尿路感染现状,并进行相关危险因素分析,为预防导管相关尿路感染提供依据。方法选取2014年1月~2016年12月我院收治的968例留置导尿管患者作为研究对象,采集患者尿液送检并分离菌株。结果共检出病原菌137株,主要以革兰阴性菌和真菌为主;单因素分析显示,女性、年龄≥60岁、住院时间≥14 d、留置尿管时间≥7 d、ICU入住时间≥7 d、糖尿病是发生导管相关尿路感染的危险因素(P<0.05);Logistic回归分析显示,女性(β=0.56,OR=3.42,95%CI 1.98~3.65)、年龄≥60岁(β=0.79,OR=2.46,95%CI 1.32~4.59)、住院时间≥14 d(β=0.54,OR=2.53,95%CI 1.23~3.87)、留置尿管时间≥7 d(β=0.82,OR=2.62,95%CI 1.11~4.20)、ICU入住时间≥7 d(β=0.24,OR=1.45,95%CI 1.03~3.48)、糖尿病(β=0.58,OR=2.56,95%CI 1.44~4.03)均为导管相关尿路感染的独立危险因素(P<0.05);ICU病房感染率高于普通病房,差异有统计学意义(P<0.05)。结论我院导管相关尿路感染率较高,危险因素较多,应采取相应的干预措施加以预防。

Objective To analyze the current situation of catheter-related urinary tract infection in our hospital,and analyze the risk factors,so as to provide basis for the prevention of catheter-related urinary tract infection.Methods From January 2014 to December 2016,968 patients with indwelling catheter in our hospital were selected as the research objects,urine samples were collected and strains were isolated.Results A total of 137 pathogenic bacteria were detected,mainly Gram-negative bacteria and fungi.Univariate analysis showed that female,age≥60 years old,hospital stay≥14 days,indwelling catheter≥7 days,ICU stay≥7 days,diabetes mellitus were the risk factors of catheter-related urinary tract infection(P<0.05).Logistic regression analysis showed that women(β=0.56,OR=3.42,95%CI 1.98-3.65),age≥60 years(β=0.79,OR=2.46,95%CI 1.32-4.59),hospital stay≥14 days(β=0.54,OR=2.53,95%CI 1.23-3.87),indwelling time≥7 days(β=0.82,OR=2.62,95%CI 1.11-4.20),ICU stay≥7 days(β=0.24,OR=1.45,95%CI 1.03-3.48),diabetes(β=0.58,OR=2.56,95%CI 1.44-4.03)were independent risk factors of catheter-related urinary tract infection(P<0.05).The infection rate in ICU was higher than that in general ward,and the difference was statistically significant(P<0.05).Conclusion Catheter associated urinary tract infection rate of our hospital is higher and it has many risk factors.Therefore appropriate intervention measures should be taken to prevent it.
