Goal 2: Reduce Human Disease

Blood Donor and Component Factors that Influence Clinical Outcomes of Transfusion

Are donor factors (age/sex), whole blood processing methods and/or red cell storage solutions associated with in-hospital mortality and/or other measures of transfusion efficacy or harm in patients who have received red cell transfusions?

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Compelling Question (CQ)

Details on the impact of addressing this CQ or CC

There is growing evidence that donor factors (age, race-ethnicity, and/or sex), method of whole blood processing, and/or the additive solution used for red cell storage could affect the quality of the red cell product and contribute to patient adverse events. For example, red cell rigidity and oxygen saturation varies between premenopausal women and postmenopausal women and men, suggesting that donor age and/or sex may be important factors affecting red cell quality and patient outcomes. A retrospective Canadian study suggested that older blood was associated with in-hospital mortality until 2006; however, after that time the risk of in-hospital mortality increased when fresher blood was transfused. This change coincided with introduction of the buffy coat method suggesting that whole blood processing methods may affect patient outcomes.

Feasibility and challenges of addressing this CQ or CC

The most efficient way to explore these issues is through the use of large dataset that can link donor demographics, product processing and recipient transfusion and outcome data. Recipient datasets are available and the feasibility of linking blood donor and blood product information has been demonstrated, making it possible to address the research question stated above.
