Modern relevance of Hippocratic Oath

Several parts of the Hippocratic oath have been removed or re-shaped over the years in various countries, schools, and societies as the social, religious, and political importance of medicine has changed. Most schools administer some form of oath, but the great majority no longer use the ancient version, which forbade general practitioners from surgery, abortion, and euthanasia.
Also missing from the ancient Oath and from many modern versions are the complex ethical issues that face the modern physician. It has been suggested that a similar oath should be undertaken by scientists, a Hippocratic Oath for Scientists.
Changed portions of the oath:
1. To teach medicine to the sons of my teacher. In the past, medical schools would give preferential consideration to the children of physicians. Some still do.
2. To practice and prescribe to the best of my ability for the good of my patients, and to try to avoid harming them. This beneficial intention is the purpose of the physician. However, this item is still invoked in the modern discussions of euthanasia.
3. Never to do deliberate harm to anyone for anyone else's interest. Physician organizations in most countries have strongly denounced physician participation in legal executions. However, in a small number of cases, a doctor can perform euthanasia, by both his and the patient's consent.
4. To avoid violating the morals of my community. Many licensing agencies will revoke a physician's license for offending the morals of the community ("moral turpitude").
5. To avoid attempting to do things that other specialists can do better. The "stones" referred to are kidney stones or bladder stones, removal of which was judged too menial for physicians, and therefore was left for barbers (the forerunners of modern surgeons). Surgery was not recognized as a specialty at that time. This sentence is now interpreted as acknowledging that it is impossible for any single physician to maintain expertise in all areas. It also highlights the different historical origins of the surgeon and the physician.
6. To keep the good of the patient as the highest priority. There may be other conflicting 'good purposes,' such as community welfare, conserving economic resources, supporting the criminal justice system, or simply making money for the physician or his employer that provide recurring challenges to physicians.

Hippocratic Oath

Hippocratic Oath is an oath taken by physicians pertaining to the ethical practice or conduct of medicine. It is believed that the Hippocratic Oath was written by the father of medicine, Hippocrates.. The Hippocratic Oath is considered to be a rite of passage for medical practitioners. I swear by Apollo the physician and AEsculapius, and Health, and All-heal, and all the gods and goddesses, that, according to my ability and judgment, I will keep this Oath and this stipulation to reckon him who taught me this Art equally dear to me as my parents, to share my substance with him, and relieve his necessities if required; to look upon his offspring in the same footing as my own brothers, and to teach them this art, if they shall wish to learn it, without fee or stipulation; and that by precept, lecture, and every other mode of instruction, I will impart a knowledge of the Art to my own sons, and those of my
teachers, and to disciples bound by a stipulation and oath according to the law of medicine, but to none others. I will follow that system of regimen which, according to my ability and
judgment, I consider for the benefit of my patients, and abstain from whatever is deleterious and mischievous. I will give no deadly medicine to any one if asked, nor suggest any such counsel; and in like manner I will not give to a woman a pessary to produce abortion. With purity and with holiness I will pass my life and practice my Art. I will not cut persons labouring under the stone, but will leave this to be done by men who are practitioners of this work. Into whatever houses I enter, I will go into them for the benefit of the sick, and will abstain from every voluntary act of mischief and corruption; and, further, from the seduction of females or males, of freemen and slaves. Whatever, in connection with my professional practice, or not in connection with it, I see or hear, in the life of men, which ought not to be spoken of abroad, I will not divulge, as reckoning that all such should be kept secret. While I continue to keep this Oath unviolated, may it be granted to me to enjoy life and the practice of the art, respected by all men, in all times. But should I trespass and violate this Oath, may the reverse be my lot

The Hippocratic Oath is an Oath that every doctor is expected to obey.
