A predictive model to reduce allogenic transfusions in primary total hip arthroplasty

An efficient Blood Conservation Program (BCP) should be considered in preparation of the surgical patient transfusion requirement. BCP should account for the association between bleeding reduction and anemia during or post surgery. In this paper, our aim was to develop a predictive model of bleeding that could help direct decision making about the strategy to reduce unnecessary transfusions. Such a strategy could guarantee an adequate peri-operative hemoglobin value, to reduce the patients’ risk and rehabilitation time. Moreover, an accurate prediction of bleeding and anemia helps to plan preventive autologous transfusion or erythropoietic stimulus, to enhance a conservative transfusion approach, reducing both costs and risks.
