老年患者留置尿管致院内泌尿系感染的相关因素分析

Analysis on the related factors of nosocomial urinary tract infection in elderly inpatients with indwelling catheter

目的分析老年患者住院期间留置尿管发生泌尿系感染的相关因素，了解留置尿管老年患者泌尿系感染状况，为预防和控制泌尿系感染提供依据。方法通过查阅病历、护理记录、尿常规和尿培养等化验报告与科室院内感染小组成员填写的医院获得性感染资料相结合的方法，对某院老年科2008年2月至2010年2月留置尿管老年患者（年龄≥60岁）的泌尿系感染状况进行分析。结果本组224例留置尿管患者中发生泌尿系感染者82例，占36．5％。留置尿管的老年患者发生泌尿系感染情况与其年龄、性别、留置尿管的时间、尿管的护理措施等因素有关。结论严格掌握老年患者留置尿管指征，尽量减少老年患者的置管率，缩短置管时间，积极治疗原发病，针对不同感染情况加强管道护理是降低院内泌尿系感染的有效措施。

Objective To explore the current status and related factors of nosocomial urinary tract infection in elderly inpatients with indwelling catheter so as to provide basis for prevention and control of urinary tract infection. Methods Medical records, nursing records, urine routine and urine culture of elderly patients aged 60 or above in a geriatric department from February 2008 to February 2010 were combined with data recorded by nosocomial infection supervisors to analyze the status of urinary tract infection caused by indwelling catheter. Results The rate of urinary tract infection in the 224 objects was 36.5% （82 cases）. Factors related to urinary tract infection in elderly inpatients with indwelling catheter were age, gender, days of indwelling catheter use and its nursing care methods. Conclusions Nosocomial urinary tract infection rate can be effectively decreased by restvictedly controlling the use indication of indwelling catheter among elderly patients to minimize their use of such catheter, shortening the days of urinary catheter use, focusing on the control of primary diseases and intensifying the nursing care of the urinary catheter according to their infection status.
