Objectives: Trials comparing the effects of transfusing RBC units of different storage durations have considered mortality or morbidity as outcomes. We perform the first economic evaluation alongside a full age of blood clinical trial with a large population assessing the impact of RBC storage duration on quality-of-life and costs in critically ill adults.
Design: Quality-of-life was measured at 6 months post randomization using the EuroQol 5-dimension 3-level instrument.
