The current study was carried out to find the microbiological profile along with the risk factors and antibiotic sensitivity patterns of catheter-associated urinary tract infection in a teaching hospital. All the catheterized patients satisfying the criteria of catheter-associated urinary infection (CAUTI) and catheter-associated asymptomatic bacteriuria (CA-ASB) were included in the study. Urine samples received from CAUTI patients were followed-up further. Samples were collected and inoculated on MacConkeys agar and Blood agar. Identification and antibiotic sensitivity patterns of bacterial isolates were carried out by automated system, i.e., Vitek-2, as per standard protocols. Duration of catheterization and various risk factors were also recorded in detail. Out of 247 urine samples of hospital acquired infection, 50 samples satisfied the criteria of CAUTI. The most common organism isolated was Escherichia coli (38%), followed by Pseudomonas sp. (24%) and Klebsiella sp. (24%). Maximum isolates were from the medicine ward (40%). Gram-negative isolates showed dominance over the Gram-positive isolates. Such increasing figures of CAUTI incidents pose a great challenge to the hospital management and threat to the patients with underlying illness. With strict adherence to the catheter care of patients and use of infection control practices, we can significantly decline the rate of developing CAUTI.
