Prior to the acceptance of the concept of brain death under the Uniform Determination of Death Act in 1980, all organ donors fell under the protocol now called Donation after Circulatory Death. In the 2000s, the organ procurement and transplantation community returned to accepting organ donation after circulatory death as an acceptable, approved method. This allows non-brain dead patients with specific clinical profiles who have suffered non-survivable brain injuries through either traumatic or clinical brain injuries to donate their organs and help save the lives of patients awaiting transplant.
