the intro of the lancet article:
Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We
evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring
the worst-off , maximising total benefits, and
promoting and rewarding social usefulness. No single principle is
sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined
into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points
systems, quality-adjusted life-years, and disability-adjusted life-years. We recommend an alternative system—the
complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates
prognosis, save the most lives, lottery, and instrumental value principles.
