Medical fallibility and the autopsy in the USA

The theory of 'necessary fallibility', originated by Gorovitz & MacIntyre (1976, In Science, Ethics and Medicine, Hastings Center, NY), explains a major unfamiliar reason for unavoidable errors in medicine. A brief historical review is presented of autopsy studies assessing the accuracy of clinical diagnoses, and of changing perceptions of the public and physicians leading to the current misconception in the USA that all errors are avoidable. It is suggested that a prospective autopsy study is needed to test the theory of 'necessary fallibility'. Validation of this theory would benefit an understanding of medical fallibility by the public and physicians, and challenge current practices in the management of malpractice and patient injury.
