Abstract

Catheter associated urinary tract infection is one of the common hospital-acquired infections which leads to the risk of sepsis, increasing the duration and cost of treatment. Determining the rate of catheter associated urinary tract infection, the clinical characteristics as well as microbiological characteristics in patients with urinary catheters at the Viet - Oxford - Department of Hospital for Tropical Diseases in Ho Chi Minh city from August 2022 to December 2023. Among 192 patients with urinary catheters, there were 111 males (58.0%) and 81 females (42.0%), the mean age was 55.3 ± 18.5 years old, with patients ≥ 60 years old accounting for 45.3%. The rate of catheter associated urinary tract infection was 24% and 22.3/1,000 catheter - days. Patients hospitalized for longer than 23 days have a 3.5 times higher risk of urinary tract infections related to catheterization. Two or more catheterizations increase the risk of catheter-related urinary tract infections by more than 4 times. Prolonged urinary catheterization time (longer than 7 days) increases the risk of catheter-related urinary tract infections by nearly 3 times. Gram-negative bacteria accounted for 60.0% of cases, with Escherichia coli (23.6%) and Klebsiella pneumoniae (18.2%) being the most prevalent. Gram-positive bacteria accounted for 23.6%, with Enterococcus faecium (7.3%) and Enterococcus faecali (9.1%). Among the bacteria, the carbapenem resistance of K. pneumoniae (70%) is noteworthy.
