Cold platelets matched fresh units while cod skin shortened hospital stays
Platelets stored cold for 21 days matched surgical outcomes from fresh units kept for 7 days. Burn patients receiving cod-skin dressings left hospital 12 days earlier in a matched comparison.

Cold storage did not change bleeding outcomes
Apheresis platelets stored at four degrees for up to 21 days did not differ significantly from room-temperature units kept for up to 7 days in bleeding-related outcomes after complex cardiac surgery. Complication rates, including clotting, also showed no difference. The study published in JAMA directly compared cold and room-temperature units. The result shows that longer storage delivered performance similar to units considered fresh for postoperative bleeding control.[1]
Shelf life widens the transport window
The possibility of tripling shelf life increases the time available to move a donation to regions far from collection centres. The cold-platelet finding assesses that logistical gain alongside patient outcomes: the longer shelf life showed no penalty in the study's bleeding and complication measures. The result therefore concerns both storage technique and the supply window that could broaden where donations can be used. The retained evidence provides no separate data on implementation across different health systems.[1]
Discharge came earlier in the cod-skin comparison
Among 465 adults treated at 49 burn centres from 2019 to 2025, the 93 people who received cod-skin dressings before grafting were discharged after 23 days on average, compared with 35 days in the matched synthetic-dressing group. Complications such as sepsis were 8 per cent and 16 per cent respectively; burns covered 13 per cent of the body on average. The manufacturer funded the study but did not analyse the data. The groups were not randomised, so a head-to-head trial is still needed.[2]
