About The Study: Red blood cell (RBC) transfusion was common in patients admitted to 233 intensive care units in 30 countries between 2019 and 2022, with high variability across centers in transfusion practices. Although many different clinical reasons and triggers were stated for RBC transfusion, the three most common reasons (low hemoglobin level, active bleeding, hemodynamic instability) and triggers (hypotension, tachycardia, no physiological trigger affected the decision to transfuse) were largely overlapping in all regions.
