The average daily number of WB recipients was 0.5 who received an average of four WB units per patient. LTOWB was issued in packages of five and all had to be consumed before a group A patient could be switched to GAWB.

The median (IQR) GAWB and LTOWB units transfused per month was 2 (0\u20139) and 56 (42\u201372), respectively. Fourteen percent of group A patients received any quantity of GAWB. The variations that had the most impact on GAWB usage included increasing the number of WB recipients to 2.5 per day where the median (IQR) monthly number of GAWB recipients and units transfused increased to 4 (3\u20135) recipients and 21 (12\u201329) units, respectively, and when the average WB requirements increased to eight units per patient resulting in transfusing a median (IQR) of 10
