There is an implemented full blood tracking in Germany for somewhat more than a decade, and it is realized by forms that have to be filled for every single unit by the physicians on the wards, emergency departments, OR and so on. These forms get sent back to the blood bank, where the usage gets documented electronically. Through the recent years we got a coverage of 98 to 100% of all units. Though laborious for the transfusing staff, this really helps to reduce wastage. Best regards, Norbert
