Purpose:
To analyze the cost consequences of autologous versus allogeneic transfusions.
Methods:
Costs were determined when allogeneic transfusions were given in addition to, or instead of, autologous transfusions. Hospital charges were used to estimate costs for hip-replacement surgery. The main outcome measure was estimated incremental hospital costs per unit transfused.
Results:
Among donors of autologous blood, mean total charges were $7,200 greater for recipients of both autologous and allogeneic transfusions than for recipients of autologous transfusion only (P=0.0001). Each allogeneic transfusion was associated with additional costs of $1,480. In a second cohort of patients receiving identical amounts of either allogeneic or autologous blood (mean=2.3 units), total hospital charges were a mean of $4,800 greater (P=0.0001) for allogeneic recipients. The per unit excess costs associated with each unit of allogeneic blood cohort were $1,043.
Conclusions:
Allogeneic transfusions are associated with incremental hospital costs of about $1,000 to $1,500 per unit transfused when compared with costs for similar patients receiving no transfusions or 1 to 5 units of autologous blood.
