Background: Among the Health care associated infections, Urinary tract infections are the most common, accounting for up to 40% of infections reported by acute care hospitals. Also, 70 - 80% of urinary tract infections are associated with the presence of an indwelling urinary catheter. So, a periodical surveillance system is essential to establish effective infection control and prevention program.

Aims

1. To determine the rate of Catheter Associated Urinary Tract Infection (CAUTI),
2. To isolate and identify the antibiotic sensitivity pattern of the isolates.

Setting: This study was undertaken in patients admitted in the Intensive Medical Care Unit (IMCU) for ≥48 hrs and on Foley’s catheter.

Methodology: In a catheterized patient, urine sample were collected aseptically. Total 168 catheterized patients were included for a period of six months. Standard proforma was used to collect all the demographic details. Colony count of 10⁵ was taken as significant. p value of <0.05 is considered significant.

Results: The mean age of patients was 37 ± 19 years. A total number of 41(24.40%) patients were culture positive. Bacterial cause was identified in 17 (41 %) and in 24 (59 %) patients Candida species were isolated. The most common bacteria isolated was Escherichia coli. The rate of Extended-spectrum β-Lactamase production was 78%. In the present study, the rate of development of CAUTI was higher with longer duration of catheterization. p value 0.033946.

Conclusions: In an IMCU setting, the catheterized patients are highly susceptible to infection. As the rate of development of CAUTI is significantly associated with the duration of catheterization emphasis should be made on reducing the duration of catheterization.
