The use of epoetin alfa does not reduce the incidence of red-cell transfusion among critically ill patients, but it may reduce mortality in patients with trauma. Treatment with epoetin alfa is associated with an increase in the incidence of thrombotic events. (ClinicalTrials.gov number, NCT00091910 [ClinicalTrials.gov].).

In critically ill patients, weekly administration of 40 000 units of rHuEPO reduces allogeneic RBC transfusion and increases hemoglobin. Further study is needed to determine whether this reduction in RBC transfusion results in improved clinical outcomes.

The administration of rHuEPO to critically ill patients is effective in raising their Hct concentrations and in reducing the total number of units of RBCs they require.
