In an important article, Rodriguez-Baño et al¹ assessed risk factors for community-acquired infections caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli urinary tract infections (UTIs), since the knowledge of factors associated with this emerging clinically relevant pathogen is scarce. Nonetheless, we are concerned about 2 issues in this study.

First, health care–associated infections are a relatively novel clinical entity distinct from community-acquired infections with characteristics that resemble those of nosocomial infections.² Thus, it was surprising that patients with such infections were not excluded from the study. Even though this variable was controlled in a multivariate model, the statement that health care–associated infections and recent hospital admission are risk factors for community-acquired ESBL-producing E coli UTI is not compatible with the mean of community-acquired infection. In addition, the finding of urinary invasive procedure . . . [Full Text of this Article]
