In Australia we have a compulsory opt-in system as far as organ donation goes. If one wishes to donate one's organs it has to be done in writing. Of course on the majority of occasions this doesn't get done/isn't done/isn't clear and organs that could be used go to waste. There's another level of complexity in that the next of kin may override an individuals opt-in wishes on any grounds. Combined with the very restricted medical circumstances in which organs are suitable for transplantation, a severe organ shortage results. I've often been interested in the idea of an opt-out system. In such a system everyone, irrespective of who they are, is on the organ donation list. If they object there's a routine, simple, and easy method in place to opt-out. This will of course greatly increase the number of people from whom organs can be sourced if they satisfy the necessary medical criteria. So I was interested in what you guys thought. What does your country/state/community do? What do you do? What are your thoughts on organ donation and ways in which the participation rates could be greatly increased? Is organ donation such a widely acceptable charitable act that the wish to donate organs could be an assumed unless otherwise indicated?
