Joint surveillance and correlation analysis of antimicrobial resistance and consumption of seven targeted bacteria, 2017–2023

This study found rising resistance among major hospital-acquired pathogens, including E. coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Staphylococcus aureus, and Enterococcus spp. Resistance increased to key antibiotics such as piperacillin/tazobactam, cefepime, carbapenems, and linezolid. Importantly, the analysis showed a positive correlation between hospital antimicrobial consumption and multidrug-resistant bacterial isolation rates, underscoring the impact of antibiotic use on resistance trends.
