We have Referig. in OR but thinking to get rid of it. Eventhough we have referig in OR, some time in emergency situation they take cooler directly to room and after emergency is over they tend to forget about the cooler. We use to waste lots of unit like that. We use a form to track the unit once it leaves the blood bank. OR staff needs to write the time they place unit in the referig, the time unit is taken out of referig, the time unit return to referig(if not transfused) and time unit return to blood bank. We also require date and signatures.
