Epidemiology and antimicrobial resistance patterns of urinary tract infection: insights and strategies from a 5-year serial cross-sectional study in Vietnam.

Background: Urinary tract infection (UTI) is one of the most common bacterial infections in clinical practice. Given the rapid increase in antimicrobial resistance and the scarcity of new antibiotics, along with the absence of individual antibiogram testing in some countries, there is an urgent need for robust surveillance systems.

Objective: This study aimed to provide evidence for the surveillance of resistance, a crucial component in developing national UTI treatment guidelines and guiding empirical therapy decisions.
