[Autologous blood donation versus homologous blood transfusion--an analysis of cost effectiveness].

Cost-efficiency analysis for autologous transfusions begins with the calculation of the pure production costs. They amount to $35-$75 for one unit of red blood cell concentrate (RBC). One homologous RBC is billed with $80 in Germany. Following factors further increase costs of an autologous blood predeposit: Autologous blood frequently is transfused more generously. The expiration-rate of autologous blood is higher. The haemoglobin content of the second and following RBC is lower. The patient himself has lower haemoglobin on the day of surgery after an autologous blood donation. In scientific examinations it is possible to refer additional costs of autologous blood to a gained "quality adjusted life year". They amount to $40,000 to $1,800,000.
