Hi Dawn, We use trained staff to transport our coolers for Emergency transfusions. They are not dedicated for this purpose in that it is not their only job. It is paramount that patient identification, in writing, be given to these runners for ID purposes. We have used Blood Bank staff, then Security and now ICU technicians. We do not have dumbwaiters. We do have to sort of look after our transport coolers to make sure they are returned otherwise in the past they have wound up lost in the transit following the patients care. For example ER to OR to ICU to IR back to OR etc..
