Microbiologic profile and clinical practices in urinary tract infections in a tertiary care center in Southern India

Studies reported differences in clinical profiles of urinary tract infections (UTIs) in patients with and without type 2 diabetes mellitus (T2DM). Studies on the impact of the pattern of antibiotic resistance of organisms causing UTI on actual clinical practice are lacking.

1. To study the clinical and microbiologic profiles of UTIs. 2. To compare treatment given with the prevailing antimicrobial sensitivity.

This is a cross-sectional study conducted in a tertiary care hospital.

Retrospective chart review of inpatients with UTI (N = 200, 100 each of patients with and without T2DM), aged >18 years with a positive urine culture.

We used the statistical package SPSS version 17. The categorical variables were analyzed by the Chi-square test. Data were considered significant if P value was less than 0.05.

Similar to previous Indian studies, T2DM patients with UTI had significantly more asymptomatic bacteriuria, asymptomatic bacteriuria (32% vs. 6%), previous history of UTI (25% vs. 2%), and prior catheterization (16% vs. 1%). Escherichia coli (E. coli) was the most common organism isolated and showed sensitivity pattern of meropenem > netilmicin > amikacin > nitrofurantoin. Ceftriaxone was the most common empirical therapy given in spite the prevailing low sensitivity of E. coli to it. All ASB cases were treated unlike recommendations.
