The table represents the waste rate of donated blood products at JRCS in the preintervention and postintervention periods. As a result, the postintervention waste rate decreased from 23.4% to 17.9%, and the cost of wasted blood products was reduced by approximately 640,000 yen (4,571 USD) per year.
