Urinary tract infections are the most commonly acquired bacterial infections accounting for an estimated 25-40% of the nosocomial infections. Catheterization is a potential predisposing factor of CAUTI. Study was carried out over a period of one year included 100 urine samples obtained from catheterized patients. The urine samples obtained were immediately processed in microbiology laboratory by semi-quantitative method as per standard protocol. Following isolation and identification, all the isolates were subjected to antimicrobial susceptibility testing for commonly used antimicrobial drugs. Out of 230 urine samples from catheterised patients 43.5% of cases developed catheter associated urinary tract infection (CAUTI). The most common organism causing CAUTI was found to be E. coli in 27.2% of cases, followed by Pseudomonas (20%), Klebsiella (15.4%), Enterobacter aerogenes (9%), Enterobacter cloacae (0.09%), Proteus spp. (2.7%) and Citrobacter spp. (2.7%). Gram positive cocci accounted only in 10% of CAUTI cases and Candida spp. in 11.8% of cases. Antimicrobial susceptibility testing revealed Imipenem (66.7%-94.1%) and nitrofurantoin (73.3%-88.2%) to be the most sensitive antimicrobials for frequently isolated Gram negative bacteria like E. coli and Klebsiella spp. Pseudomonades isolated were sensitive to imipenem and gentamicin (31.8% each). Gram positive cocci were completely sensitive to linazolid and vancomycin. This study reported a high rate of CAUTI (43.5%) and resistance to commonly used antimicrobials among CAUTI isolates, hence it is necessary to reduce urinary infection in catheterized patients by limiting the use of catheter only for proper indications and remove catheters promptly when no longer required.
