Medical ethics
Applied ethics analyzing clinical medicine and scientific research.
Medical ethics is a practical branch of ethics that examines how clinical medicine and scientific research should be conducted. It rests on four core values: respect for autonomy, non-maleficence, beneficence, and justice. These principles help doctors, caregivers, and families agree on treatment plans and shared goals, though no single value is always more important than another. Conflicts can arise, however, forcing a temporary hierarchy to apply the best moral judgment in difficult situations. This field is especially relevant when decisions involve involuntary treatment or commitment.
Several codes of conduct guide the profession. The Hippocratic Oath, dating to the fifth century BCE, outlines basic principles for medical professionals. Two other respected documents are the Nuremberg Code (1947) and the Declaration of Helsinki (1964). Key historical events also shaped medical ethics. The development of hemodialysis in the 1960s raised ethical questions about prioritizing scarce equipment, which later evolved into dilemmas about whether to continue treatment for patients who lack decision-making capacity or exhibit behavioral issues. The 1973 U.S. Supreme Court decision Roe v. Wade, which legalized abortion under the Constitution, was overturned in 2022, returning power to states to regulate access. This reversal creates moral conflict when a doctor might face legal punishment for providing an abortion to save a patient’s life.
As the field evolves, it remains focused on fair, balanced, and moral thinking across all cultural and religious backgrounds. Medical ethics applies both in clinical practice and in scholarly work within philosophy, history, and sociology. It addresses conflicts involving euthanasia, patient confidentiality, informed consent, and conflicts of interest. Culture also plays a role: different societies may emphasize family values over individual autonomy, increasing the need for culturally sensitive physicians and hospital ethics committees.
Medical ethics defines relationships in three directions: between a medical worker and a patient, between a medical worker and a healthy person (such as relatives), and between medical workers themselves. It covers medical confidentiality, medical errors, iatrogenesis, and the duties of both doctor and patient.

Lore & Background
The term medical ethics first dates back to 1803, when English author and physician Thomas Percival published a document describing the requirements and expectations of medical professionals within medical facilities. The Code of Ethics was then adapted by the American Medical Association in 1847, relying heavily on Percival's words. Over the years in 1903, 1912, and 1947, revisions have been made to the original document. Historically, Western medical ethics may be traced to guidelines on the duty of physicians in antiquity, such as the Hippocratic Oath, and early Christian teachings. A document sometimes cited in discussions of early medical regulation is the Formula Comitis Archiatrorum, though its dating is uncertain—often placed in the 9th century or later—and it is not considered the first code of medical ethics, as the Hippocratic Oath predates it by centuries.
Reader's Guide
Medical ethics is particularly relevant in decisions regarding involuntary treatment and involuntary commitment. The four core values—autonomy, non-maleficence, beneficence, and justice—are not ranked in order of importance, but conflicts may arise leading to the need for hierarchy in an ethical system. Well-known documents include the Hippocratic Oath (5th century BCE), the Nuremberg Code (1947), and the Declaration of Helsinki (1964). Historical milestones that impacted medical ethics include the development of hemodialysis in the 1960s, which raised concerns about prioritizing patients due to scarcity of equipment, and the overturning of Roe v. Wade by the Supreme Court in 2022, which created conflicts regarding moral judgment if a doctor should be legally punished for providing an abortion to save a patient's life. The field continues to develop, focusing on fair, balanced, and moral thinking across cultural and religious backgrounds. Medical ethics is closely related to bioethics and the law, but ethics often implies a higher standard of behavior than the law dictates.
