Frequency of Catheter induced urinary tract infection in patients undergoing major gynecological and obstetrical surgeries at a local tertiary care hospital.

Abstract

Objective: The aim of this study was to determine the frequency of catheter associated urinary tract infections in patients undergoing major gynecological & obstetrical surgeries.Methodology: This cross-sectional study was conducted in the Department of Obstetrics & Gynecology, Liaquat National Hospital & Medical College, Karachi. Duration of this study was six months from 1st December 2018 till 31st May 2019. A total of 246 patients were included in the study. Sample collection was done using non probability consecutive sampling technique. Patients who had routine catheter insertion for duration of 1-2 days during major gynecological and obstetrical surgeries were included in this study. Results: A total of 246 patients who met the inclusion and exclusion criteria were included in the study. Patients were divided according to the duration of post-operative catheter exposure days (1 & 2). Sixty five patients were reported to have catheter induced urinary tract infection (UTI) with an overall infection rate of 26.4%.The highest rate of urinary tract infection (47.5%) was reported in patients who had their catheters removed on post-operative day 2. Most prevalent organism causing catheter induced UTI was reported to be E coli (22.4%). Chi Square test showed statistical significant association with p value 0.001 with the duration of catheterization removal and catheter induced UTI. Conclusion: Prolonged duration of indwelling Foley catheter in post-operative Gynecology patients was associated with an increased incidence of Urinary Tract Infection. Multiparous women are more prone to get CAUTI as compared to nulliparous women.
