Current Trends in Nosocomial Associated UTI (NAUTI) in Urology Ward

Background: Nosocomial associated urinary tract infections are common, which not only causes morbidity and mortality but also increases cost of health related expenditure in urology patients. Such infections are more difficult to treat because of presence of risk factors e.g. stone, reduced kidney functions. Limited studies are available which focus on type of organisms involved in NAUTI and their presentation in urology departments. Objective: To determine the proportion of microorganisms involved in Nosocomial associated urinary tract infections (NAUTI) and their presentations in urology ward. Methods: This cross-sectional study was conducted in Dubai Hospital in Dubai UAE, from 2017-2018. All patients, who were admitted in urology department with negative urine cultures, were included in study. Urine cultures were sent at time of discharge and a week after discharge from hospital. Patients were followed up in outdoor at first and second week. Results: Total 475 patients were included in this study in given time period. 315(66.31%) patients were male and 160(33.68%) patients were female. On their first follow up after a week, Urine cultures, which were sent at discharge time reveals,73(15.36%) patient’s urine cultures were positive, out of them 21(28.76%) were Mixed Bacterial Growth (MBG). E.coli was most common organism 20(27.39%) in which 11(15.06%) were ESBL positive, klebsiela 9(12.32%) in which 4(5.47%) were ESBL positive. Other organisms include Psuedomonas 4(5.47%), candida 16(21.91%) and enterococcus 3(4.11%). Frequency of candida was second highest, probably because of use of antibiotics during admission. Conclusion: Prevalence of NAUTI in urology is 19.79% (94/475 patients). Enterobacterale species were main responsible organisms for NAUTI in Urology ward. E.coli was most common organism isolated and klebsiela was second most common. Key words: Nosocomial UTI, ESBL UTI, Urology ward
