Risk factors and outcomes for the acquisition of carbapenem-resistant Gram-negative bacillus bacteremia: A retrospective propensity-matched case control study

Risk factors for acquisition of CR GNB bacteremia identified in this study each may serve as a reminder alerting clinicians to hospitalized patients at risk for CR GNB bacteremia requiring appropriate antibiotic coverage, and in these circumstances, combined antibiotics may be used until antimicrobial de-escalation/adjustment is clearly indicated by the subsequently identified pathogenic GNB and its susceptibility profile.
