Blood conservation techniques are underutilized in Canadian orthopedic surgery. Few eligible patients participate in autologous blood donation, leading to higher allogeneic transfusion rates.

Area of Science:

  • Orthopedic Surgery
  • Transfusion Medicine
  • Patient Blood Management

Background:

  • Blood conservation techniques minimize risks associated with allogeneic blood transfusions in elective surgery.
  • Allogeneic blood products carry risks including infection and transfusion reactions.
  • Optimizing blood management is crucial for patient safety in orthopedic procedures.

Purpose of the Study:

  • To examine transfusion practices and blood conservation strategies in elective orthopedic procedures across 19 Canadian hospitals.
  • To assess the utilization of autologous blood donation and other blood conservation methods.
  • To identify factors influencing participation in autologous blood donation programs.

Main Methods:

  • Retrospective review of 4535 medical records for total hip or knee arthroplasty patients (June 1998-January 1999).

  • Data collected included pre/postoperative hemoglobin, comorbidities, autologous donation status, and transfusion occurrences.
  • Eligibility criteria for autologous donation: weight ≥25 kg, good health, hemoglobin ≥110 g/L.

    • Main Results:

    • 57.9% of 4422 eligible patients could have donated blood autologously, but only 18.6% did.
    • Patients not predonating were older and had more comorbidities.
    • Allogeneic transfusion rates were 30.6% for non-donors vs. 14.1% for donors; other conservation techniques were used minimally (2.4%).

    Conclusions:

    • Blood conservation technique adoption in Canadian hospitals is low.
    • Autologous blood donation is underused among eligible orthopedic surgery patients.
    • Increased utilization of blood conservation strategies is needed to reduce allogeneic transfusions.
