The Reduction of Preoperative Autologous Blood Donation for Primary Total Hip or Knee Arthroplasty: The Effect on Subsequent Transfusion Rates

Abstract

We compared two transfusion policies for primary total hip or knee arthroplasties: first, a standard preoperative autologous donation with a liberal autologous transfusion policy; and second, a more restrictive indication for autologous donation that was based on patients' individual factors, with identical criteria for autologous and allogeneic transfusion. We found that this change of policy reduced autologous donation and transfusion with no increase in allogeneic transfusion.
