Urinary Tract Infections in Patients Hospitalized in a Gastroenterology Department—Study from a Tertiary Regional Hospital in South-East Poland

Abstract

A retrospective analysis of urine culture results was conducted for adult patients treated between 1 January 2017 and 31 December 2021 at the Department of Gastroenterology in Rzeszow (southern Poland). A total of 102 patients were sampled for microbiological tests during the analyzed period, with microbial growth found in 30 samples. The purpose of our study was to determine the predominant bacterial species present in the urine of patients hospitalized in the Department of Gastroenterology, as well as their drug susceptibility. The data obtained from medical records included, for example, urine culture results and the antibiotic susceptibility of the isolated microorganisms. The material for the study was collected according to the current procedures. During the analyzed period, urine was collected from a total of 102 patients, and 30 positive samples were found. The predominant pathogen was Escherichia coli (n = 10 (33.33% of all positive results), p < 0.001); the second most common microorganism was Enterococcus faecalis (n = 5 (16.67% of all positive results), p < 0.001). In vitro susceptibility testing showed E. coli, ESBL (ESBL strain with extended-spectrum beta-lactamase) (n = 2 (6.67% of all positive results), p = 0.055) and Klebsiella pneumoniae, ESBL (n = 3 (10% of all positive results), p = 0.005). Urinary tract infection (UTI) was an extremely common problem.
