On the face of it the 'new thinking', (the opt-out system), has a great deal going for it and may well represent a great leap forward.
I presume that in a life support switch off scenario the attending relatives would be consulted whether or not the individual had opted-in or opted-out of organ donation.* [I have been faced with the formality of signing a 'release/permission' for a dangerous procedure to be performed on an adult loved-one, "we don't need to ask you...we could go and just do it" I'm still not entirely sure why they did this, but everything worked out in the end.]
Although I have no personal experience of a sudden death as a result of an accident, at work or on the road, coming to the situation some time after the event, it might be some comfort that some good had come of it. Certainly coming too late for the donation option one might feel the waste of a stranger's chance of a new lease of life added to one's own loss. There is also the other side of the coin; you, or someone you know, may be the one that is waiting.
While there always has been an element of trust, even with our NHS, now that the profit motive is flooding into health provision, the water is muddying-up. Would the grieving relatives be faced with the dilemma of cashing-in themselves** and the dread that money is influencing the call that useful life is all but extinct? Speaking for myself, I am very much a, "Where there is life there is hope!" kind of guy.
*Do we wish to thrash out the nature of this assumed contract or is this taken care of with the necessary 'talking it over' within the family?
**I don't quite mean that the relatives will take part in a Dutch Auction:switch-off now for £X, switch-off tomorrow for £x, just underlining the trust issue.
