Cost analysis of intraoperative blood salvage during orthotopic liver transplantation

Approximately 6,000 to 7,000 orthotopic liver transplantation (OLT) procedures are performed annually, which require the administration of large volumes of blood products. Thus liver transplantation can significantly strain local and regional blood resources at a time when transfusion practices are changing dramatically, in large part because of anxiety caused by the human immunodeficiency virus. Intraoperative autologous transfusion has been proposed as a means of both reducing transfusion demands and lessening the hazards of allogeneic transfusion. However, the cost effectiveness of intraoperative blood salvage has not been unequivocally determined. We retrospectively examined the cost of intraoperative autologous transfusion during OLT for a 2-year period at the University of Cincinnati Hospital. A direct comparison was made between the charge for autologous transfusion and the calculated cost of allogeneic transfusion. Seventy OLT procedures were performed during the years 1993-1994. The average charge for autologous transfusion was $1,048.73 per case. Cell-salvage volumes for all cases were added, and the calculated conservation of allogeneic packed red blood cells totaled 359.6 units, worth $30,026.60 or $428.95 per case. The break-even point is approximately 12.6 units, and most patient do not receive this volume of salvaged blood. In fact, cell salvage reached cost equivalence in only three cases (4.8%). Moreover, the cost deficit of autologous transfusion during this 2-year period averaged $586.56 per case.
