Urinary tract infections (UTIs) after catheterization are the most common infections and account for up to 40% of all health-related infections. With the catheter-associated UI (CAUTI) it was 1.41 / 1000 catheter days. It is estimated that up to 4% of patients with bacteriuria will eventually develop clinically significant bacteriuria with a death rate of 13-30%. After catheterization, the risk of acquiring bacteriuria increases over time with an average daily risk of 3% to 10% per day. This study was conducted to determine the confirmed CAUTI rate, prevalence of organisms and their susceptibility patterns. A total of 1258 Foley’s catheter cases were followed up for 24 months. Cases were confirmed according to the NABH Standards and Centers for Disease Control and Prevention guidelines. 46 cases of CAUTI (29 cases in 2018 and 17 cases in 2019) were confirmed in 1258 catheterized individuals. The most common isolate was Escherichia coli (41.86%). Isolates were found to be resistant to cotrimoxazole, 2nd and 3rd gen cephalosporins, fluoroquinolones, and decreased sensitivity to other urinary antibiotics. To reduce morbidity, length of hospital stay and patient costs, unnecessary catheter insertion should be avoided. If Foley catheter insertion is required, aseptic precautions should be taken during catheter insertion and the Foley extraction performed as soon as possible. and health worker training and surveillance by infection control teams play an important role in improving practice and reducing infection.
