Cost Analysis of Therapies for Severe Anemia

The goal of this observational study is to learn about the costs that occur when participants with severe anemia are treated with blood transfusions or with patient blood management (PBM). PBM means that the body of the participant is stimulated to produce new blood by itself rather than receiving it from a blood donor, and to reduce blood losses. The main question the study aims to answer is: Do participants treated with transfusions incur the same treatment costs than participants treated with PBM? And how much costs are this in relation to the lives saved by the therapy of severe anemia?
