[Clinical information, informed consent and medical deontology. A recent relationship]

In Spain, the right to clinical information and informed consent as a practical expression of the principle of autonomy, are legal conquests achieved in the late twentieth century. From the law they have been transferred to the codes of medical deontology. The aim of this work is to study the pace of this transfer. Historical review of the different codes of medical deontology in Spain since the Civil War, seeking the presence of these ideas in them. Until code of medical deontology of 1979, the idea of clinical information did not appear in the contemporary deontological norm, and the rules on consent did so in very restricted cases. As of that date, their appearance is progressive in the successive codes. Currently, both concepts are fully developed in Spanish deontological regulations. Medical Deontology has take on the ideas of patient information and informed consent. This has been a long process which have brought considerable changes the deontological orientations of the traditional form of doctor-patient relationship. In these aspects, medical deontology has drifted, from emphasizing the prudence of the doctor, to emphasize the duty to inform and give ample space to the patient's decisions, which he recognizes as an autonomous and reflective moral agent, capable of taking his own decisions about your health.
