Catheter associated urinary tract infection among patients attending some selected hospitals in Kano Metropolis

Abstract

Background: Catheter-associated urinary tract infection has become one of the major global health concerns, especially in developing countries including Nigeria. Risk factors for CAUTIs include prolongation of the catheterization and possible contamination of the indwelling catheter by normal microbial flora.

Aim: The present study aimed to evaluate catheter-associated urinary tract infection among patients attending some selected hospitals in the Kano metropolis.

Methodology: This is cross sectional prospective study among 231 consented patients, ages ≥18 years that were catheterize. Urine samples were collected and subjected to standard bacteriological procedure for culture and sensitivity test. Patient data were collected using structured questionnaire.

Result: The overall CAUTIs incidence of 163(70.6%) was obtained in this study, Escherichia coli was the highest uropathogene 62(38.0%) obtained followed by 58(35.6%) with Staphylococcus aureus. Majority of the participants are male 89(54.6%) and participants within the age group of 68 – 77 years had the highest incidence 37(22.7%) and least incidence was obtained among ages group ≥88 years 3(1.8%). Nitrofurantoin and Amoxicillin were found to be the most active antibiotics. Prolonging stay of the catheter showed the great impart in the occurrence of CAUTIs.

Conclusion: An incidence rate of 70.6% was obtained in this study. The present study revealed the presence of bacteria associated with urinary catheters in individuals with UTIs. High incidence was observed in male participant than female counterpart.
