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

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.

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.

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 49.5% reduction in PLT transfusions. Smaller-sized hospitals also had reductions in transfusion volumes, while some volumes increased at hospitals when new or expanded clinical services were introduced. The number of RBC units per transfused recipient was generally between 1.5 and 2 units on the wards and slightly higher in the ICUs.

Although the overall volume of transfusions has generally decreased at each hospital site over time, the appropriateness of the administered transfusions cannot be evaluated by these data.

The system-wide implementation of a PBM program has reduced transfusion volumes.
