That's a useless suggestion: people who need organ donations are generally not suitable to donate, and they know it long ahead of time.
Except in cases of injury, or where only one organ is the problem.
Well, one reason is a concern that doctors and hospitals might be less interested in saving you if that means potentially damaging donatable organs. There are many other reasons as well.
Considering that, far as I can tell anyway, virtually every medical organization on earth denies that happens, that seems an extremely unlikely and unreasonable concern. I would not be surprised if there were isolated incidents, but by that logic you should wear body armor in case someone stabs or shoots you. I think its much more reasonable to trust the opinions of major medical organizations than put stock in baseless fears pulled out the usual place.
Good point, I forgot to apply Hanlon's razor to the situation. I should have said prick or conspiracist with unreasonable fears. If there were any evidence whatsoever that organ donors die at a higher rate in emergency situation (are emergency medical staff even aware of your status in those situations?), it would be huge medical ethics news. Somehow I doubt that is the case.
I think they should be tied together. Unless you have some sort actual medical reason as to why you should not be an organ donor (HIV infection, ect.) opting out should put you on the bottom of the donation list should you need it. If you contribute to the system, you get priority if you need the system. Otherwise, you go to the back of the line. Don't expect to receive if you're not willing to give.
I just don't get the mentality of people who refuse organ donation. If you're dead, you're dead, why take other people with you? It's one last act of good that could save lives and, seeing as how you're never going to use them again, costs you absolutely nothing. How big of a prick do you have to be to look at that proposition and reject it?
