Abstract

Background: Urinary tract infection (UTI) caused by bladder catheterization is one of the most common infections in healthcare settings. The main determinant for the development of bacteriuria is the timing of urinary catheterization. Research objectives: Determine the prevalence of bladder catheter-related infections and find out the causes of nosocomial UTIs related to bladder catheters. Subjects and research methods: A cross-sectional descriptive study. The study subjects included 98 patients with bladder catheterization over 48 hours at the Toxicology Department, Nghe An Friendship General Hospital from January 2022 to August 2022. Results: The proportion of patients in the study group over 50 years old was the highest with 58.54%. The proportion of male patients was higher with 70.4%, female patients was 29.6%. And the frequency of urinary tract infections related to bladder catheters was 17.2 patients per 1000 days of catheterization. There were 88.89% of urine samples only cultured one type of microorganism. In which, the most common microbial causes of UTIs are fungi with the rate of 50%, Gram (-) bacteria accounting for 35% and Gram (-) bacteria accounting for 15%. Conclusion: The rate of urinary tract infection in patients with bladder catheterization was 18.37%, of which men over 50 years old accounted for a higher proportion. There were 88.89% of urine samples only cultured 1 type of microorganism, of which mainly fungi with the rate of 50%, especially Candida albicans accounting for 25%.
