We have 11 remote refrigerators around our facility. Most wastage occurs in the operating room areas, especially the fridges in the two CVOR suites. Because of this, we decided a few months ago to pilot a new process for the OR's. They have been very motivated to reduce wastage but very frustrated with the rate at which the temp indicators turn color on their red blood cells. We acquired a bunch of small, conventional coolant gel packs and we started to sandwich each red blood cell unit between two of them and wrapping with a rubber band. We positioned the unit label, tag and temp indicator in such a way that the unit could be checked before storing it in the OR fridge. We send the blood to the OR through the pneumatic tube (which sometimes results in slight delays of someone retrieving them. After several months, we have seen significant reduction in the temp indicators changing (wastage) and it was relatively easy to train the OR staff to be compliant with this. They will sometimes take the unit out of the gel packs before putting it in the fridge (along with the get packs) so they can send the unit back to blood bank in the gel packs if they don't transfuse it. This may all sound cumbersome but it has been generally successful and much cheaper than throwing away units of fresh O Neg!
