Notes: Carbapenem-resistant isolates are defined as Enterobacterales, which were resistant to any of the resistant to meropenem, imipenem, and ertapenem; A. baumannii and P. aeruginosa which as any of the resistant to meropenem and imipenem.
Abbreviations: BSIs, bloodstream infections; IAIs, intra-abdominal infections; RIs, respiratory infections; UTIs, urinary tract infections; CR, carbapenem resistant; ESBL, extended-spectrum beta-lactamases.
