Abstract
The demand for donor organs for transplantation in the UK far exceeds the supply. A number of improvements in the infrastructure surrounding organ donation, as well as attempts to increase public awareness, have been made over recent years, but there remains a massive shortfall. It has been proposed that a system of presumed consent for organ donation, in which all individuals are considered to be potential organ donors after death unless they have previously opted out, may serve to increase the supply of organs. Recently the Welsh Assembly passed a Bill introducing presumed consent by 2015, but the debates regarding legislative changes are still on-going in England, Scotland and Northern Ireland. The ethical implications of presumed consent legislation are at the centre of these discussions. When examined by a principlist approach, presumed consent may be deemed to be an ethically beneficial measure to increase organ donation rates. It is argued here that the system of presumed consent may actually be more respectful of the principle of autonomy than a system of explicit consent, on the basis that it goes against the wishes of the fewest number of people, and it has clear benefits in terms of beneficence and justice whilst also being compatible with the principle of nonmaleficence. Although there is some debate about the precise impact that presumed consent would have on donation rates, there is evidence to suggest that it would result in an increase in the donor organ supply, when combined with improvements in education and infrastructure.
