Informed consent has become a standard part of medical practice over the past half-century (Berg et al., 2001). In the twentieth century, at a high point of other movements toward expansion of civil and individual rights, a series of court cases delineated the doctrine of “informed consent” for the first time. Prior to this time, consent, if it existed at all, was based on a concept of a simple consent – disclosure of information was not considered necessary; the patient just had to agree to treatment. In some situations, merely the fact that a patient sought treatment in the first place, along with the fact that they did not leave when treatment was begun, was deemed adequate consent.
