There has been a recent increase in the incidence of urinary tract infections (UTIs) caused by extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae, which are resistant to third-generation cephalosporins. Our goal was to compare the clinical responses of patients with ESBL UTI and non-ESBL UTI who received empiric third-generation cephalosporins. A retrospective analysis was performed on data collected between June 1, 2013, and June 30, 2017, from children aged 0 days to 19 years old who presented to NYU Langone Long Island Hospital’s pediatric ED and/or were admitted with a UTI caused by Enterobacteriaceae. There was no significant difference in median length of fever duration. However, ESBL patients had significantly longer hospital stays, higher 30-day readmission rate, and higher 7-day revisit rate. It is reasonable to maintain an empiric UTI antibiotic choice rather than selecting a broad-spectrum antibiotic, such as carbapenem for children at high risk of ESBL UTI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
