Priority in Organ Allocation to Previously Registered Donors: Public Perceptions of the Fairness and Effectiveness of Priority Systems

A priority system is one in which previously registered donors receive a preference in the allocation of organs for transplant ahead of those who have not registered. Supporters justify these systems on the basis that they are fair and will encourage donor registration. This article reviews existing studies of public reactions to priority systems, as well as studies of the extent to which the moral principle of reciprocity affects decision making in organ donation. The role of reciprocity in the public discourse surrounding the enactment of priority systems in Singapore and Israel is described. One factor that seems to have been relevant in these countries is the existence of a religious minority that is perceived as willing to take an organ but not to donate one. Although this perception may have fueled a resentment of perceived “free-riders,” concerns were raised about the social divisiveness of priority systems. In sum, people appear to be sensitive to the principle of reciprocity in the context of organ donation, but this sensitivity does not always translate into support for priority systems. Further research into whether public messaging about organ donation could be modified to encourage registration by appeal to the golden rule would be worthwhile.
