Informed Consent adalah Persetujuan yang diberikan oleh klien atau keluarganya atas dasar informasi dan penjelasan mengenai tindakan medis yang akan dilakukan terhadap klien tersebut.
Informed consent is a doctrine that anyone who participates in human research must do so voluntarily and must know enough about the study to make an intelligent decision about whether to take part. A health care provider may ask a patient to consent to receive therapy before providing it, or a clinical researcher may ask a research participant before enrolling that person into a clinical trial. Informed consent is collected according to guidelines from the fields of medical ethics and research ethics. This term was first used in a 1957 medical malpractice case by Paul G. Gebhard.
