A Comparative Evaluation of ESBL Production and Carbapenem Resistance in UTIs Before and During COVID-19

Abstract

Background: The COVID-19 pandemic has heightened the urgency to address antibiotic resistance, particularly ESBL and carbapenem-resistant UTIs. Our study seeks to assess the pandemic's effect on the prevalence of these resistances, comparing data from before and during COVID-19. By identifying trends in resistance patterns, we aim to enhance antibiotic stewardship and inform healthcare policies. Understanding the pandemic's impact on ESBL and carbapenem resistance is vital for guiding clinical practices and public health initiatives in tackling antibiotic resistance. Methods: This retrospective study, conducted at King Fahad Medical City in Riyadh, Saudi Arabia, analyzed positive urine cultures from January 2018 to December 2022 to assess the prevalence of antibiotic resistance among UTIs. Using WHO-recommended semiquantitative culturing methods on CLED and blood agar, bacterial isolates were identified via the BD Phoenix system and antimicrobial susceptibility was assessed following CLSI guidelines. ESBL detection employed the Double-Disc Synergy Test. Data analysis involved SPSS for statistical evaluation, utilizing chi-square and t-tests for categorical and continuous variables, respectively, and logistic regression to explore associations between variables and antibiotic resistance, with significance set at p
