We have a Central Transport Department that picks up most of our blood from the Blood Bank, even during MTPs (MTP=Massive Transfusion Protocol). We have a pneumatic tube system, but we don't use it for blood products except when sending them to our satellite lab in the CV unit.
We don't have insulated carriers; I don't even know if that is an option, but the transport time is so short that it doesn't matter, and since it is going to another lab, we are confident that it will be taken out of the PTS station quickly and put into controlled temperature storage.
When I worked next door (large university hospital) they started using their pneumatic tube system to send blood all over the hospital. This was 'suggested' by consultants as a way to save money. They have had some challenges, but overall I think it works ok.
Our pharmacy uses the PTS, but I don't know what procedures they have in place to ensure the right drug goes to the right place. I know they have them; I just don't know what they are.
