e19501 Background: Cytotoxic chemotherapy for hematologic malignancies may adversely affect myelopoiesis, resulting in profound neutropenia that predisposes patients to severe infections. Patients undergoing hematopoietic stem cell transplantation (HSCT) are at particularly increased risk. Neutropenia is defined by an absolute neutrophil count (ANC) 10 hour delay to antibiotic initiation. Fortunately, there have not been any severe morbidity or mortality outcomes yet. Next steps are to deploy a quality improvement initiative to increase speed to fever identification, blood culture draw, and empiric antimicrobial delivery.
