Background: Catheter-associated urinary tract infection (CAUTI) has a wide range of etiological agents, many of which are multidrug-resistant. Early, adequate antibiotic therapy based on culture sensitivity reports, as well as infection control procedures, are critical in the treatment of CAUTI.
The goal of this study was to determine the prevalence of CAUTI in critical care unit (ICU) patients.
2. To identify the etiological factors that cause CAUTI.
3. To identify the antimicrobial susceptibility pattern for the bacteria found.
Patients with urinary catheters admitted to ICUs provided urine samples from clinically suspected instances of CAUTI. Wet mount, culture, and sensitivity testing were performed on urine samples. Based on CSLI criteria, the responsible microorganisms and their antimicrobial susceptibility pattern were identified.
Results: A total of 640 patients had an indwelling urinary catheter for a total of 5199 catheter days during the course of six months. Out of 45 clinically suspected CAUTI cases, 19 had a positive culture. 3.65 cases of CAUTI per 1000 catheter days was the rate. Citrobacter species (26.3 percent), P. aeruginosa (21.1 percent), and E. coli were the most common etiological agents responsible for CAUTI (21.1 percent ). Among Enterobacteriaciae, 2 (18.2%) ESBL-producing Gram-negative bacteria were found. For Enterobacteriaceae, ceftazidime/clavulinic acid, colistin, and meropenam were the most effective antibiotics; for P. aeruginosa, piperacillin/tazobactam; and for Enterococcus species, linezolid and vancomycin were the most effective antibiotics.Author (S) Details
