Abstract

Background: Catheter-associated urinary tract infections (CAUTIs) are the most common nosocomial infection affecting all age groups and are a leading cause of morbidity and mortality in hospitalized patients. The etiological agents are often multidrug resistant.

Objectives: 1. To find the incidence of CAUTI in intensive care unit (ICU) patients. 2. To identify etiological agents responsible for CAUTI. 3. To determine antimicrobial susceptibility pattern for bacterial agents obtained.

Methods: Urine samples from 210 clinically suspected cases of CAUTI were obtained from patients with urinary catheters admitted in ICUs. Urine samples were subjected to wet mount, culture and sensitivity testing. Responsible pathogens and their antimicrobial susceptibility pattern were obtained based on CSLI standards.

Results: The incidence of CAUTI in the present study was 16%. Higher incidence of CAUTI (55%) was found in male sex as compared to females (45%). Incidence of CAUTI was found higher as the days of catheterisation increased. Most predominant etiological agents responsible for CAUTI were E.coli  (69.69%) followed by klebsiella species (15.15%) .25% isolates among Enterobacteriaciae were ESBL producing. Uropathogens isolated from CAUTI are more resistant to antimicrobials.

Conclusions & Prevention: It is must to implement following strategy for reducing the risk of infection due to indwelling catheters: 1. reducing the duration of catheterization 2. early removal of catheters, 3. aseptic insertion 4.  maintenance of a closed urinary drainage system.5 Strict infection control measures
