A STUDY ON CATHETER ASSOCIATED UTI IN ICU PATIENTS IN A TERTIARY CARE HOSPITAL
Dr. D. B. Shanthi MD*
Introduction: Catheter associated urinary tract infection is an important healthcare associated infection. More than 80% of nosocomial UTIs are catheter- associated. Patients in intensive care unit have more risk of acquiring catheter associate UTI. Based on this our aim is to determine the incidence rate of symptomatic catheter associated urinary tract infection in intensive care unit set-up, to isolate the organisms involved in symptomatic catheter associated UTI, to determine the antimicrobial sensitivity pattern of the isolates. Materials & Methods: A total of 200 patients admitted in medical ICU and put on Foley’s catheter were included in the study and followed up for the development of symptomatic CAUTI. The urine samples from the catheter were collected on day 1 and then on day 3,5,7 and every weekly till the patient is in hospital. The samples were processed as per standard guidelines. Results: Total 52 patients developed Symptomatic catheter associated UTI, thereby the incidence being 26 %. Pseudomonas aeruginosa was the commonest isolate followed by Klebsiella pneumoniae, Escherichia coli, Enterococcus faecalis and Candida spp. each. High degree of antibiotic resistance was observed. On the whole the bacterial isolates were more sensitive to piperacillin-tazobactam, imipenem and meropenem. Conclusion: Development of catheter associated UTI is common in critically ill patients Emphasis should be placed on good catheter management and reducing the duration of catheterization to reduce its incidence. Knowledge of resistant pattern can help in implementing proper antibiotic therapy and infection control policy.[Full Text Article]
