Amikacin 27 (56.3) 86 (89.6) <0.001
Gentamicin 32 (68.1) 88 (93.6) <0.001
Ceftazidime 30 (63.8) 93 (96.9) <0.001
Cefepime 22 (45.8) 73 (76.0) 0.001
Piperacillin/tazobactam 25 (52.1) 77 (80.2) 0.001
Ampicillin/sulbactam 17 (36.2) 62 (65.3) 0.002
Ciprofloxacin 33 (68.8) 93 (96.9) <0.001
Imipenem 13 (27.1) 47 (49.0) 0.020
Multidrug resistancea 31 (64.6) 94 (97.9) <0.001

aDefinition: resistance to three or more of the following classes of antimicrobial agents: anti-pseudomonal cephalosporins, anti-pseudomonal carbapenems, ampicillin/sulbactam, fluoroquinolones, and aminoglycosides.
