Organ donation and pre-emptive kidney transplantation: ethical issues

There is considerable evidence that pre-emptive transplants have several clinical advantages. However, pre-emptive transplants raise a number of ethical issues. Pre-emptive transplants from living donors offer distinctly greater benefits than those from deceased donors and some pre-emptive transplantation programmes actively encourage living organ donations. Moreover, the offer of a pre-emptive transplant to a patient who is not yet on dialysis unquestionably penalises patients already on dialysis who may have been on the waiting list for a long time. Therefore pre-emptive transplants give rise to conflicts between justice and utility. Several factors should be considered: health conditions, clinical urgency, probability of imminent worsening of a patient's clinical condition, the future chances of finding a matching organ, and others. From the various values at stake, ethical issues are analysed in search of an acceptable synthesis.
