Abstract
Objective: To assess the prevalence of urinary tract infection (UTI) in the Intensive Care Unit (ICU) sector of a hospital in southern Brazil and its association with sociodemographic and health variables, including the use of a bladder catheter. Methods: Retrospective, cross-sectional study, including adult patients admitted to the ICU of the Teaching Hospital of the Federal University of Pelotas, in 2019. Data collection occurred through the review of the medical records of the Medical and Statistical Archive Service. Results: 140 patients admitted to the hospital's ICU were identified, with a 62.9% prevalence of UTI. Individuals who developed UTI remained with a bladder catheter for a longer time (mean of 18.35 days) than those who did not develop it (p <0.001). Klebsiela pneumoniae was observed in 46.6% of the exams, followed by Acinetobacter baumanii (28.4%) and Escherichia Coli (18.2%). The main antibiotics used were meropenem, piperacillin + tazobactan and polymyxin B (33.0%). Conclusion: These findings make it possible to contribute to the formulation of new intervention strategies, focusing on updating care practices and continuing education for health professionals, reducing the prevalence of this infection.
