Semi-quantitative culture of urine samples was done by calibrated loop method on 5% sheep blood agar and CLED agar (cystine–lactose–electrolyte-deficient agar and incubated in aerobic conditions at 37☌ for24-48 hours. The urine samples were subjected to wet mount for evaluating the presence of pus cells, epithelial cells, RBCs and microorganisms. This plays a significant role in initiating appropriate antibiotics which decreases complications and hospital stay and also helps the infection control team to implement proper care bundles which reduces the hospital stay of patients there by reducing the morbidity and mortality. 6 The present study was done to assess the incidence of CAUTI in a tertiary care hospital, to identify the uropathogens associated with it and to detect the antibiotic sensitivity pattern in the isolated organisms. In addition, hospital acquired CAUTIs are often due to multidrug resistant strains which require higher antibiotics. Complications associated with CAUTI cause discomfort to the patient, prolonged hospital stay, and increased cost and mortality. 5 CAUTI can lead to complications such as prostatitis, epididymitis, and orchitis in males, and cystitis, pyelonephritis, gram-negative bacteremia, endocarditis, vertebral osteomyelitis, septic arthritis, endophthalmitis, and meningitis. Bacteria can easily invade the lower urinary tract along the external surface of the catheter or by ascending route through the lumen of the catheter. The duration of catheterization is directly related to the development of infection. 3, 4 The urethral catheter is the most prevalent cause of nosocomial infections and gram-negative bacteremia. These include quality of aseptic technique, duration of catheterization, appropriate hand hygiene and care of catheter. 2 Multiple risk factors can affect the occurrence of CAUTI. 1 Catheter-associated urinary tract infections (CAUTI) according to the centers of disease control and prevention(CDC) is defined as UTI where an indwelling urinary catheter was in place for more than two calendar days on the date of event (day 1 being the day of device placement). Between 15-25% of hospitalized patients receive urinary catheters during their hospital stay leading to Catheter Associated Urinary Tract Infections (CAUTI) where care bundles are not practiced. Among hospital acquired UTIs, approximately 75% are associated with a urinary catheters. Implementation of proper care bundles and continuous education to health care workers plays a key role in reducing the CAUTI rates, thereby decreasing the morbidity and hospital stay to the patients.Ĭatheter associated Urinary tract infection (CAUTI) is the most common among the device associated infections acquired from the hospital settings. catheter days over a 2 month period.ĭiscussion and Conclusion: CAUTI remained a great burden to patient safety and a challenge to the infection control team. 2300 catheter days were obtained of 460 patients on indwelling catheter in ICU. Of 28 urine samples cultured, 4(14%) yielded growth of single organis and 24(86%) showed no evidence of growth. Results: Among 460 patients on catheter in ICU, 28(6%) patients developed clinical signs or symptoms of UTI. CAUTI rate was calculated and results were noted. Uropathogens were isolated, identified and subjected to antibiotic sensitivity test. Under aseptic conditions urine samples were collected from clinically suspected cases of CAUTI, the samples were processed in the department of Microbiology, as per standard protocols. Materials and Methods: The Patients admitted in intensive care unit (ICU), Rajarajeshwari Medical College and Hospital who were on urinary catheter insertion for >48 hours from 1 August, 2019 to 30 September, 2019 were included in the study. Objectives: Aim of the present study was to determine the etiology with antibiotic susceptibility and also to calculate CAUTI rate. This emphasizes the need to implement and monitor effective infection control programs to reduce the risk of CAUTI. Introduction: Catheter-associated urinary tract infections (CAUTI), remains the commonest hospital-acquired infection (HAI).
