Risk factors for community-onset urinary tract infections caused by extended-spectrum β-lactamase-producing Escherichia coli

The increasing prevalence ofESBL-producing E. coli makes it difficult to decide the empirical therapy in UTIs, especially in patients with two or more of the risk factors. A better understanding of the epidemiology and risk factors associated with community-onset UTIs due to ESBL-producing E. coli may have significant implications in decision-making for empirical antimicrobial treatment.
