Data mining: Digging for deeper understanding of blood components and transfusion outcomes

What is this research about?

There is no question that blood transfusions save lives. Whether some blood products lead to better patient outcomes than others, however, has been up for much discussion. For the past 15 years, the biggest question has been: Does transfusing “older” red blood cells (i.e. those that have been stored longer before transfusion) lead to worse patient outcomes? The results of more than 50 observational studies investigating this question were contradictory, but recent clinical studies show no evidence of worse outcomes when older red blood cells are transfused.
