Medical ethics is a system of moral principles that apply values and judgments to the practice of medicine. As a scholarly discipline, medical ethics encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, and sociology Historically, Western medical ethics may be traced to guidelines on the duty of physicians in antiquity, such as the Hippocratic Oath, and early rabbinic and Christian teachings. In the medieval and early modern period, the field is indebted to Muslim medicine such as Ishaq bin Al Rahawi(who wrote the Conduct of a Physician, the first book dedicated to medical ethics) and Muhammad ibn Zakariya ar-Razi (known as rhazes in the West), Jewish thinkers such as Maimonides, Roman Catholic scholastic thinkers such as Thomas Aquinas, and the case-oriented analysis(casuistry) of Catholic moral theology. These intellectual traditions continue in Catholic Islamic and Jewish medical ethics By the 18th and 19th centuries, medical ethics emerged as a more self-conscious discourse. For instance, authors such as Thomas Percival wrote about"medical jurisprudence"and reportedly coined the phrase "medical ethics. Percival's guidelines related to physician consultations ha been criticized as being excessively protective of the home physician s reputation. Jeffrey Berlant is one such critic who considers Percival's codes of physician consultations as being an early example of the anti-competitive, "guild-like nature of the physician community. In 1847. the American Medical Association adopted its first code of ethics, with this being based in large part upon Percival's work 3].

Values in medical ethics Six of the values that commonly apply to medical ethics discussions are: Autonomy - the patient has the right to refuse or choose their treatment. Beneficence - a practitioner should act in the best interest of the patient. Non-maleficence - "first, do no harm". Justice - concerns the distribution of scarce health resources, and the decision of who gets what treatment (fairness and equality). Dignity - the patient (and the person treating the patient) have the right to dignity. Truthfulness and honesty - the concept of informed consent has increased in importance since the historical events of the Doctors' Trial of the Nuremberg trials and Tuskegee Syphilis Study. Values such as these do not give answers as to how to handle a particular situation, but provide
