Changes in blood product utilization in a seven-hospital system after the implementation of a patient blood management program: A 9-year follow-up

Objectives: To analyze changes in red blood cell (RBC), platelet (PLT), and plasma transfusion volumes 9 years after the implementation of a multifaceted patient blood management (PBM) program across multiple hospitals.Methods: Between fiscal years 2007 and 2015, the annual transfusion volumes for seven hospitals in a regional healthcare system were analyzed by hospital, and between 2014 and 2015, by four service lines including emergency department, intensive care unit (ICU), medical/surgical ward, and operating room at each hospital. The number of units of RBCs administered to transfused recipients on the wards and in ICUs was also enumerated.Results: For these seven hospitals combined, there was a 29.9% reduction in the number of RBCs transfused between 2007 and 2015, a 24.8% reduction in plasma units, and a 25.7% reduction in PLT units. The two largest hospitals saw some of the largest reductions in RBC transfusions (40.1, 25.1%), and plasma transfusions (26.1, 33.8%), and one of those hospitals had a...
