Ethical reflections on the principle of patient autonomy.

In a world open to the movement of people, medical ethics is today associated with the area of loyal behavior of the practitioner and oriented in the patient's interest and accountability of each. The universal vision of respect for the dignity of the sick person progresses. Yet, many behaviours are sometimes illegitimate, but not in principle legally reprehensible. One of the main principles marking the observance of patient consent is based on the autonomy given to the patient to decide for himself what appears to be adapted to his or her care. The patient must be the one who makes the final decision on issues concerning them and doctors must act to respect it. Therefore, they must accept that the patient has a different value system.
