Impact of Extended-Spectrum <i>β</i> -Lactamase–Producing <i>Escherichia coli</i> and <i>Klebsiella</i> Species on Clinical Outcomes and Hospital Costs: A Matched Cohort Study

Abstract

The cost of non-urinary tract infections caused by ESBL-EK was 1.7 times the cost of non-urinary tract infections caused by non-ESBL producers. Prompt recognition and appropriate antimicrobial selection may minimize this ESBL-related impact on hospital costs.
