Lee H, et al. - The risk factors of urinary tract infection (UTI) caused by extended-spectrum β-lactamase (ESBL) E. coli in the Emergency Department (ED) were determined. The main risk factors identified were hospital-acquired infection, prior UTI within 1 year, and underlying cerebrovascular disease. Researchers recommended considering these factors when treating UTI patients in ED. The outcome of empirical treatment could be enhanced with amikacin without increasing carbapenem utilization.
