Assess longitudinal trends in relative isolation frequency and antimicrobial resistance patterns among major bloodstream pathogens across general wards and intensive care units.
Analyzed routine susceptibility surveillance data for 50,488 blood culture isolates collected from hospitalized patients across 25 tertiary hospitals between January 2010 and December 2017.
Evaluated only the first isolate per bacterial species per patient, stratifying analyses separately for hospital wards and intensive care units.
Acinetobacter baumannii isolation frequency rose in wards, accompanied by increasing multi-drug non-susceptibility across both wards and intensive care units.
Klebsiella pneumoniae isolation frequency decreased while resistance to carbapenems and gentamicin increased; concurrently, Escherichia coli showed rising isolation frequency and resistance to third-generation cephalosporins, carbapenems, and fluoroquinolones.
Meticillin-resistant Staphylococcus aureus proportions declined in intensive care units, Pseudomonas aeruginosa non-susceptibility decreased for all agents except imipenem, and vancomycin-resistant Enterococcus faecium remained stable.
