Objective The aim of this study was to identify the risk factors and common pathogens associated with catheter-associated urinary tract infection (CAUTI) in the ICUs of Assiut University Hospital, Egypt. Methods Urine samples were collected from patients suffering from CAUTI according to the case definition of Centers for Disease Control and Prevention. The samples were subjected to culture on different culture media, and all positive colonies were identified according to their biochemical profile and antibiograms. Klebsiella isolates were further tested for extended-spectrum β-lactamase production. Results The overall bacterial CAUTI incidence rate was 11% (15/136 patients). Female sex, old age (>60 years old), diabetes mellitus, and prolonged duration of catheterization (>6 days) were found to be risk factors for the development of bacterial CAUTI. Klebsiella was the commonly isolated microorganism (8/16, 50%). All Klebsiella isolates were found to be phenotypically Extended-spectrum β lactamase producers, and five of these isolates contained either blaTEM or blaSHV genes. Conclusion This study revealed the high incidence of bacterial CAUTI (11%) in ICUs of Assiut University Hospital. ESBL-producing Klebsiella spp. is responsible for about 50% of bacterial CAUTI cases. All isolated microorganisms were found to be multidrug resistant. Strict implementation of infection control procedures appears to be necessary to control the spread of multidrug resistant organisms.
