For thousands of years, ethics have been recognized as an essential requirement for any profession. The ancient codes of ethics have to some extent stressed this requirement.
The Western medical code of ethics have evolved from the ancient Hippocratic Oath and western principles of gentlemanly honor. Standards of professional behavior were codified in the late17th century and officially adopted by medical associations as early as the mid-19th century.

The Islamic medical ethics are primarily based on the Qur'anic ethics which stand out a perfect model for all mankind, all professions, and in all time.

The origins of medical and research ethics are examined below:

Hippocratic Oath (400 BC)
Hippocrates (Born in Greece 460 BC) is known as the Father of Medicine. He founded a medical school and developed an Oath of Medical Ethics for physicians to follow.

The Hippocratic Oath has formed the basis of more recent healthcare oaths taken by graduates as they begin their practice.

The chief tenants of this Oath are:

Honour the instructors of the medical arts.Pass on the Art only to those bound by the Oath.Practice for the benefit of patients, "do no harm".Avoid deadly medicine or substance to produce abortionEnter homes for the benefit of the patient.Abstain from mischief and corruption.Respects the Doctor-patient confidential relationship.

Thomas Percival (1740-1804)
An English physician established in 1794 a code of medical ethics for physicians that were adopted by American doctors and later by the American Medical Association (AMA). This was the first code of ethics to be adopted by a professional organization replacing the variously interpreted ethics of gentlemanly honor and thus providing a standard of behavior for medical professionals.

American Medical Association ( AMA) Code of Ethics (1846)
The (1980) version of AMA code of ethics has seven articles, while the updated version (2001) contains nine articles. The additional articles in the current version stress physician’s responsibility, and support of universal access to medical care. In addition, the latest version added all required provisions regarding a commitment to medical education and a responsibility for the improvement of public health. The AMA code has some other features like:

The respect of the law.The respect of the patient’s rights.The respect of colleague’s rights.The respect of patient’s privacy and confidentiality.The dedication, competence, and compassion.The honesty and duty to report fraud or deception.The continued education, study, and consultation with other professionals.The freedom of association and environment in the practice of the Art.The responsibility to make efforts to improve the community

Nuremberg Code (1947)
Nuremberg code is a result of the post World War II (WWII) trial of a group of Nazi doctors, for crimes against humanity committed in the name of research. This code represents the starting point in discussions about the ethical treatment of human subjects.

German doctors, performed macabre medical experiments under the disguise of scientific research in Nazi concentration camps where prisoners were used without concern for their welfare.

The Nuremberg Code is a set of ten principles outlining the ethics of medical research and ensuring the rights of human subjects.

The principles include the following:

Informed, voluntary consent.Research must be purposeful and necessary for the benefit of society. Research must be based on animal studies or other rational justification Avoidance and protection from injury, and unnecessary physical and mental suffering Risks to the subject shall not be greater than the humanitarian importance of the problem Investigators must be scientifically qualified. Subject may terminate the experiment at any time.

Declaration of Geneva (1948)
The World Medical Association adopted this oath after the atrocities committed in the name of research in Nazi concentration camps. Key features of this code are:

Service to humanity, respect and gratitude for instructors, conscience and dignity in the practice of the Art, dutiful attention to the health of the patient, colleagues and traditions of the Art , practice in accordance with the laws of humanity, respect for human life from conception , and duty takes precedence over racial, religious, political or social prejudices.

Declaration of Helsinki (1964)
The first publication of this declaration was in 1964, as a response to unethical medical experiments of the Nazis during WWII. It has been revised several time since 1964, the latest revision of the document was in 2000 and states the following principles :

The well being of the human subject should take precedence over the interest of science
and society.The doctor should only act in the patients best interest and that the health of the patient is
the first concern.

Many of declaration’s principles are incorporated in national research regulations. On the other hand the revised document 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.

Islamic medical Ethics
The Qur'anic ethics stand out as a perfect model for all mankind, all professions, and all time. It guidelines for mankind’s behaviour and attitude, both at the personal and professional levels.

This standard of moral and ethical values should guide the Muslim health care practitioners in their private life and while conducting their professional life as well.
