“Researchers who tested the use of refrigerated platelets say their ‌results could more than triple the supply available to help save bleeding patients.

Platelets are a blood component that’s crucial for clotting and stemming blood loss. Donated platelets are conventionally stored at room temperature with a five-to-seven-day shelf life.

At 27 hospitals in the U.S. and Australia, 1,000 children and adults undergoing cardiac surgery received either room-temperature platelets stored ​for less than seven days or chilled platelets.

Platelets refrigerated for up to three weeks were just as effective at treating bleeding as ​the room-temperature platelets, the researchers reported in JAMA.

A significant proportion of the 2.5 million room-temperature platelet units collected each ⁠year in the U.S. are wasted due to the short shelf life, the researchers noted…

Presently, rural and community hospitals for the most part cannot justify keeping room-temperature platelets in stock because they don’t often treat severely bleeding patients, his team noted.”
