2675. Changing Epidemiology of Bloodstream Infection During Chemotherapy for Acute Leukemia: Impact of Prophylactic Fluoroquinolone Restriction and Carbapenem Saving Strategy

摘要

BackgroundFluoroquinolone prophylaxis has been widely used in high-risk neutropenic patients with hematological malignancies, which may reduce bloodstream infection (BSI) and mortality. However, concerns about antibiotic resistance also exist. The aim of this study was to assess the impact of new institutional strategy of restricting fluoroquinolone prophylaxis and saving carbapenem, applied since October 2016. Fluoroquinolone prophylaxis was adopted only in remission induction chemotherapy, and carbapenems were saved until other antibiotics prove no effectiveness
