The Hippocratic ethic, or medical ethics, has guided medical practitioners for 2,500 years. More recently it has been displaced by bioethics. Traditional medicalethics is a covenant between a competent physician and a sick patient, the purpose of which is to effect healing. Bioethics is a civil consensual ethic regulating health-care delivery. It is not personal by nature.Medical ethics is a deontological, virtue-based ethic. Bioethics, particularly as expressed in principlism, its most prominent school in the United States, isa liberal utilitarian ethic that emphasizes individual autonomy.Bioethics and principlism both play a role in guiding health-care delivery in a pluralistic society. However, traditional medical ethics, and not bioethics, bestaddresses the moral issues arising in the personal relationships between a treating physician and a suffering patient.
