[Guidelines for preparing informative material for obtaining informed consent from individuals undergoing diagnostic and therapeutic procedures].

The authors describe the ethical principles and legal basis of obtaining informed consent for diagnostic and therapeutic procedures. They also quote a text of proposed guidelines directed at rationalizing activities, behaviours and modalities of obtaining informed consent in a hospital setting. In line with the general objectives of guidelines, such as improvement of results through behaviour changes, including reduction of the variability of behaviour, a standard form is proposed for obtaining a valid informed consent.
