Canadian critical care physicians are using lower red blood cell transfusion triggers and more single-unit transfusions. Practice has shifted significantly since 1993, influenced by clinical trials and guidelines.

Area of Science:

  • Critical Care Medicine
  • Hematology
  • Transfusion Medicine

Background:

  • Red blood cell transfusion practices in critically ill patients require characterization.
  • Understanding changes in transfusion practice over time is crucial for evidence-based care.

Purpose of the Study:

  • To characterize current red blood cell transfusion practices among Canadian critical care practitioners.
  • To examine the evolution of transfusion thresholds and strategies over time.

Main Methods:

  • A scenario-based national survey was conducted among Canadian critical care physicians.
  • Respondents evaluated transfusion triggers in four distinct clinical scenarios.

Main Results:

  • Significant differences in transfusion thresholds were observed across scenarios (p < .0001).

  • Lower transfusion thresholds (70 g/L) were more common in trauma and septic shock compared to gastrointestinal hemorrhage and myocardial infarction.
  • A notable decrease in transfusion thresholds and a substantial increase in single-unit transfusions were reported since 1993 (56% vs. 10%).

    • Conclusions:

    • Canadian physicians have adopted lower red blood cell transfusion triggers.
    • There is an increased utilization of single-unit red blood cell transfusions in critical care settings.
