Exactly there might be a lot of other factors.

For example is familial consent is required and the answer is usually yes even in Spain AFAIK.

But that doesn’t mean they are all equal the time that it takes to contact a family and get consent plays a critical role so is who contacts them as in a professional that can explain to them the process and increase the likelihood of consent being given to some busy administrator asking them that as btw....

Also are all hospitals equipped for organ harvesting? Do they have free surgeons and free surgical staff and rooms for that? Can all hospitals handle transport and distribution of organs? How fast is donor decision can be made after harvesting?

These are all critical factors for organ donation in cases that do not involve a vegetable state patient where organ donation can be planned.

I don’t know about the UK but I have knowledge of another opt-out system in a different country and in the case if the family couldn’t be contacted in time for the organs to be harvested the reason for why not would be recorded as the same as the family refused and that is “consent was not given”.

So to me the % difference can be just that Spain is quicker at contacting the family and is more prepared for organ harvesting and distribution for ad-hoc cases in which time is critical.
