Controversy in the Determination of Death: The Definition and Moment of Death

This essay reviews recent controversy in the determination of death, with particular attention to the definition and moment of death. Definitions of death have evolved from the intuitive to the pathophysiologic and the medicolegal. Many United States jurisdictions have codified the definition of death relying on guidance from the Uniform Determination of Death Act (UDDA). Flaws in the structure of the UDDA have led to misunderstanding of the physiologic nature of death and methods for the determination of death, resulting in a bifurcated concept of death as either circulatory/respiratory or neurologic. The practice of organ donation after circulatory determination of death (DCDD) raises a number of ethical questions, most prominently revolving around the moment of death and manifested as an expedited time to determination of death, a departure from the unitary concept of death, a violation of the dead donor rule, and a challenge to the standard of irreversibility. Attempts to redefine the determination of death from an irreversibility standard to a permanence standard have significant impact on the social contract upon which deceased donor organ transplantation rests, and must entail broad societal examination. The determination of death is best reached by a clear, strict, and uniform irreversibility standard. In deceased donor organ transplantation, the interests of the donor as a person are paramount, and no interest of organ recipients or of the greater society can justify negation of the rights and bodily integrity of the person who is a donor, nor conversion of the altruism of giving into the calculus of taking.
