Paternalism is against the informed consent, though informed consent is now the mainstream of the Bioethics. It is literally interpreted as a principle that thinks hightly of paternal warmth. It is derived from "Hippocratic Oath". It insists that patients believe in doctors' conscience and skill and act as doctors tells patients to do. Historically, paternalism was born as a fundamental standard that didn't allow any doctor to violate the human rights of patient on the ground of development of medical science or treatment as a result of the regret over the experiments on human against humanity.
Ironically, paternalism became the cause of producing Bioethics represented by imformed consent, which was against paternalism. However, in actual scene of medical treatment, there are still some cases where the doctors' paternalism strongly shows itself. Such doctors say, "We are doing things benefitting patients. Leave it to us." We have developed many useful devices. Above all, the Internet provides us with much infomation. They also tells us much infomation of medical treatment: therefore, we can feel medical treatment in our own backyard. Under such circumstances, the old paternalism can result in our distrust of medical treatment.
We suggest, even if one patient is already medically treated in some ways, he/she be informed of the side effects he/she is using and another medical treatment.
