American Medical Association (AMA) Code of Ethics (1846) (full text - pdf)
The AMA Code of Ethics was adapted from the ethical code of conduct published in 1794 by Thomas Percival. This was the first code to be adopted by a national professional organization. The current AMA code of ethics (2001) has nine articles which is two more than the previous version (1980). These additions stress the responsibility the doctor has to the patient and the support of universal access to medical care. Provisions are also added to the revised Oath regarding a commitment to medical education and a responsibility for the betterment of public health. Other features of the Code are:

Declaration of Geneva (1948 - rev. 2002) (full text)
This oath for physicians was adopted by the newly established (1948) World Medical Association largely in response the atrocities committed in the name of research in WWII Nazi concentration camps. It was also meant to update the Hippocratic Oath to make it more applicable to the modern era.
Declaration of Helsinki (Adopted 1964; latest amendment 2000) (full text)
This document has been revised several times since its publication in 1964 as a response to unethical medical experiments of the Nazis during WWII. The latest revision of the declaration (2000) states that "the well-being of the human subject should take precedence over the interest of science and society." Other of the Helsinki principles are that the doctor should only act in the patients best interest and that the health of the patient is the first concern. Many of the principles are incorporated in national research regulations.
The revised declaration also discusses the use of placebo, recommends that ethics committees have the obligation to monitor ongoing trials, and requires that researchers disclose to subjects details of funding and possible conflicts of interest. Finally, there is a recommendation that publishers decline studies not carried out in accordance with the declaration.

Thomas Percival. Medical Ethics. (1803) (DALWKK W 50 P429 1803F)
The English physician, Thomas Percival (1740-1804) in 1803 published his Medical Ethics; or, a Code of Institutes and Precepts Adapted to the Professional Conduct of Physicians and Surgeons. This code, following in the tradition of the Hippocratic Oath was to influence the development of later codes of medical ethics. Indeed, the American Medical Association (AMA) adapted and adopted Percival's code for use by American physicians in 1847. The Percivalian code asserted the moral authority and independence of physicians in service to others, affirmed the profession's responsibility to care for the sick, and emphasized individual honor.
