It is a complex process, with many simultaneously moving parts. That's one of the reasons we need specialists in the area, and we have the support of donation coordinators, who help with much of this.
In fact, the notification to the organ procurement organization would usually go first to an organ donation coordinator, who would then contact the individuals in the different parts of the system. First we have to understand whether the potential donor has actually progressed to being declared dead or is a potential donation after cardiac death. Those are two different situations.
They may then talk with the potential recipient transplant teams, the physicians and surgeons, who will decide if the organ being offered is suitable to be transplanted. If it is, then the system has to search through the wait-list to find the person who is the best match or is at the top of the list.
From then, there is the organization of the actual recovery of the organs from the donor and the logistics for the transport of those organs to the different centres where the transplants are going to be carried out, which may be across the country.
There are many, many moving parts to be coordinated. All of them, however, are critically important, and that's why the system has to be highly functioning.
