Microbiological Profile and Antimicrobial Susceptibility of Microorganisms Isolated From Catheter Associated Urinary Tract Infections in an Adult Intensive Care Unit of Tertiary Care Center in Jaipur

Introduction: Urinary tract infections (UTIs) account for 20 - 50% of all hospital - acquired infections occurring in the intensive care unit (ICU). Among these, more than 80% of nosocomial UTIs are catheter - associated UTI (CAUTI). As compared to patients in a non - critical area, those in the intensive care unit have more risk of acquiring CAUTI. Objective: To isolate & identify microorganisms commonly associated with catheter - associated urinary tract infection in adult ICU patients and to determine the antimicrobial susceptibility pattern of these isolates. Material and method: This observational study was carried out in the bacteriology laboratory, Department of Microbiology, SMS Medical College, Jaipur, (Rajasthan). A total of 150 urine samples were collected from catheterized patients from adult ICU from the suspected cases of UTI. A structured proforma was used to collect data on age, gender, and clinical history. Results: On laboratory testing, among 150 clinically suspected cases of UTI, only 59 (39.3%) had significant growth and 91 (60.7%) were sterile. Among all the positive cases, the majority of the uro - pathogens were gram - negative bacilli 31 (52.5%) followed by Candida spp.17 (28.9%), gram - positive cocci were 11 (18.6%). Conclusion: Appropriate training of the paramedical staff, strict infection control practices, and an appropriate antibiotic policy, strict bundle care approach for both insertion and maintenance of catheter are the required to prevent CAUTI.
