Minimizing Blood Transfusion in Total Hip and Knee Arthroplasty Through a Multimodal Approach

Abstract

Background: We introduced a multimodal, multidisciplinary approach to perioperative blood management aimed at reducing blood transfusions in primary knee (TKA) and hip (THA) arthroplasty. The protocol included (1) preoperative hemoglobin optimization through a multidisciplinary approach, (2) minimization of perioperative blood loss, and (3) adherence to evidence-based transfusion guidelines. Methods: Evaluation of 1010 consecutive patients undergoing primary TKA (488) or THA (522) was performed. Results: A significant reduction in the overall transfusion rate (1.4% vs 17.9%, P
