Organ donation is a wonderful thing...however. Being a registered donor can take some end-of-life decisions out of family hands. For example, we had a person in our unit who was essentially already dead on the vent, and the family had a hard time making the decision to withdraw support. They finally reached that stage, and were going to make him comfort care. Per policy, we had to notify the donor network of the change in patient status, and they said, well, he's a donor, they can't make that decision. And the patient was kept "alive" another two days while donor tried to find matches for him, on pressors, receiving blood products, the whole shebang. Against the family's wishes.
