A prospective study was carried out in a medical and surgical ICU to determine the incidence of nosocomial urinary tract infection (NUTI) and to identify the most important risk factors. Over a 6 month period, 180 patients were included. All had an indwelling catheter. Six risk factors were studied: age, sex, illness (medical, surgical, trauma), hospital or extra-hospital origin, simplified acute physiology score and length of bladder catheterization. Forty three patients developed a NUTI. Length of bladder catheterization was the only significant different risk factor in infected and non-infected patients. Kaplan Meir analysis was used to determine time to development of NUTI. The risk rose from 19% for 5 day long catheterization to 50% for 14 day long catheterization.
在一家内科和外科重症监护病房进行了一项前瞻性研究，以确定医院获得性尿路感染（NUTI）的发生率，并找出最重要的风险因素。在6个月的时间里，纳入了180名患者。所有患者均留置导尿管。研究了六个风险因素：年龄、性别、疾病（内科、外科、创伤）、医院内或医院外来源、简化急性生理学评分以及膀胱导尿时间。43名患者发生了医院获得性尿路感染。膀胱导尿时间是感染患者和未感染患者中唯一有显著差异的风险因素。采用Kaplan Meir分析来确定发生医院获得性尿路感染的时间。导尿5天的风险从19%上升到导尿14天的50%。
