Epidemiology and antimicrobial resistance patterns of urinary tract infection: insights and strategies from a 5-year serial cross-sectional study in Vietnam
Abstract
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. Design: This study utilized a retrospective, serial cross-sectional design. Methods: Antimicrobial surveillance was conducted using data collected from January 1, 2017 to December 31, 2021. A total of 2595 patients with UTIs were recruited for this study. From these patients, 2004 bacterial isolates were identified and subjected to epidemiological and antibiotic resistance analyses. Results: Escherichia coli (E. coli, 42.7%), Pseudomonas aeruginosa (P. aeruginosa, 11.9%), and Klebsiella pneumoniae (K. pneumoniae, 10.9%) were identified as the predominant causes of UTIs. E. coli isolates demonstrated a high level of sensitivity (80%–90%) to carbapenems (imipenem, ertapenem, and meropenem), aminoglycosides (amikacin), piperacillin/tazobactam, cefoperazone/sulbactam, and fosfomycin. The antibiotic resistance rates of K. pneumoniae strains consistently exceeded 50%, except for amikacin, ertapenem, imipenem, meropenem, and fosfomycin. Notably, all K. pneumoniae…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 2,595 participants or records.
