Uniform Determination of Death Act

The Uniform Determination of Death Act (UDDA) is a model state law that was approved for the United States in 1981 by the National Conference of Commissioners on Uniform State Laws, in cooperation with the American Medical Association, the American Bar Association, and the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research. The act has since been adopted by most US states and is intended "to provide a comprehensive and medically sound basis for determining death in all situations". Brain death is a different condition than persistent vegetative state. Due to better seat belt use, bicycle helmets, and the general decrease in violent crime, there are lower numbers of brain deaths now than historically. Donation after cardiac death (DCD) is a new protocol applied when there is severe neurologic injury but the patient does not meet the criteria for brain death.

The three sections of the Act proposed for enactment read as follows.

Section 1
Determination of Death. An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards.

Section 2
Uniformity of Construction and Application. This Act shall be applied and construed to effectuate its general purpose to make uniform the law with respect to the subject of this Act among states enacting it.
