This is a non-concurrent cohort study that uses data from 301 patients admitted to the intensive care unit of two public hospitals in Belo Horizonte. It aimed at analysing epidemiological aspects of urinary tract infections amongst patients with indwelling bladder catheterization, evaluating the incidence rate of the infection in the two hospitals and identifying possible risk factors related to the infection. Sample consisted of patients that underwent indwelling catheterization for a period of six months. Of the 301 patients, 23 developed infection: 56.52% were male and aged 60 years and over. The overall incidence of urinary tract infection was 6.70 infections/1000 catheter-days. The hospital using water and soap for periurethral cleaning presented higher incidence of urinary infection than the hospital using antiseptic (14.01 and 3.05 infections/1000 catheter-days, respectively). Risk factor identified was periurethral cleaning with soap and water. The most prevalent microorganisms in urine cultures were Pseudomonas aeruginosa (17.39%), Candida sp. (13.04%), Escherichia coli (13.04%), and Proteus mirabilis (8.70%). This study results contradict the literature which demonstrates the need for primary research aimed at identifying the most effective solution for periurethral cleaning in order to reduce catheter-related urinary tract infections.
