Bloodstream infections caused by metallo-β-lactamase/Klebsiella pneumoniae carbapenemase-producing K. pneumoniae among intensive care unit patients in Greece: risk factors for infection and impact of type of resistance on outcomes.

Objective: To determine risk factors for bloodstream infections (BSIs) caused by Klebsiella pneumoniae producing metallo-β-lactamases (MBLs) or K. pneumoniae carbapenemases (KPCs), as well as risk factors for mortality associated with carbapenem-resistant K. pneumoniae, among intensive care unit (ICU) patients.
