In trying to adopt a consenting system for posthumous organ donation, the following considerations are relevant.
6) There was no association between favoring a consenting system and age, perceived health status, education level, or knowing an organ donor or recipient.
One needs to determine the moral focus of the public since the introduction of a consenting system without public support could negatively affect donation rates.
4) A mandatory choice system was most favored and a presumed consent system was least favored, suggesting a combination of a response to the duty of easy rescue and the importance to will/intend the act of donation.
If there had been a change to a presumed consent system we might have thought that was the reason for the increase in donation but the key seems to be the infrastructure now in place.
Several authors have argued that differences in organ donation rates between consent systems prove that a presumed consent system leads to a more effective procurement of donors [ 5- 7].
(It has been estimated that if every state in the U.S. simply switched from an "explicit consent" to a "presumed consent" system several thousand lives would be saved each year).
