Comparative Study Of Silver Coated Urinary Catheter Vs Conventional Latex Catheter In Prevention Of Catheter Associated Urinary Tract Infection

Abstract

AIMS & OBJECTIVES Comparative study of silver coated urinary catheter vs conventional latex catheter in prevention of catheter associated urinary tract infection MATERIALS AND METHODS- Out of 240, 120 patients were treated with silver oxide coated Foley’s catheter and 120 patients with conventional Foley’s after baseline urine culture was found to be sterile and between age group 18- 89 yrs were included in the study. Patients with pre-existing UTI and urogenital abnormality were excluded from the study. The urine analysis and culture for bacterial count was assessed on day 1, day 3 and day7 or more and the results were compared. RESULTS- in our study, we found that the mean age between the statistically not significant. Out of 240 study sample, 140 (59 %) were males and 99 (41 %) were females. On comparing the urine for pus cells, it was observed that there was significant decrease in the number of patients with positive urine for pus cells when there was an indwelling catheter for 7 days or more. It was also seen that the most common organism isolated was Escherichia. Coli, followed by Staphylococcus Aureus, Klebsiella Pneumonia, Pseudomonas species, and others. CONCLUSION- In our study, there was no statistical difference in distribution of patients between the study group and control group with respect to age and sex. Urine examination for evidence of pus cells was found significantly low in the study group on the Day 7 or more (up to 14 days) of urinary tract catheterization with P value – 0.027, whereas there was no difference on the incidence at the end of Day1 or Day3. Thus, we can infer from the above results that the Silver Oxide impregnated Foley’s catheter was efficacious in reducing the occurrence of Catheter related urinary tract infections.It was observed from our study that the Silver Oxide impregnation to plain Foleys catheter has the potential to prevent/reduce the incidence of catheter associated urinary tract infections in patients who need longer duration of catheterization for various reasons. It was also observed in our study that duration of study was a significant risk factor in predisposing a patient to infections.
