RESUMO
BACKGROUND: Many studies show it is not necessary to transfuse according to a single hemoglobin level, but rather it is necessary to assess the combination of signs, symptoms, and laboratory measures. PURPOSE: The purpose of this study was to evaluate the use of red blood cell (RBC) transfusions in patients who underwent total hip or knee replacement. METHODS: The study comprised 2 retrospective medical record reviews: Phase 1 included data prior to the RBC transfusion order set and elimination of autologous blood. Phase 2 included postimplementation data. RESULTS: There were a decreased number of patients receiving blood transfusions after implementing the RBC transfusion order set and a decreased hemoglobin trigger value. The strongest predictor of receiving a blood transfusion was autologous blood donation. CONCLUSION: Use of the order set will decrease unnecessary transfusions hospital-wide.
