Of the plasma recipients, 63.5% were male, with a mean age of 61.2\u2009years (SD 16.4). Most plasma transfusions were administered in the ICU (64.1%). The number of plasma units transfused per 1000 inpatient days across centers varied from a median (IQR) of 0.2 (0.1\u20130.4) to 11.0 (10.6\u201312.0) units. There was significant variability in pre\u2010transfusion INR values across hospitals (ranging from a median (IQR) of 1.5 (1.3\u20131.9) to 2.5 (1.4\u20134.6)) and physician specialties (ranging from a median (IQR) of 1.4 (1.3\u20131.8) to 2.2 (1.8\u20133.0)).
