Psychiatric advance directives (Ulysses Contract): the need for a specific law and a criteria proposal for its introduction.

Aim: Advance healthcare directives in the psychiatric field raise more concerns and controversies compared to their use in other medical branches. We discuss the role of advance directives in this field and suggest a criteria proposal for the settlement of a comprehensive regulation on the matter.

Methods: We analyse the existing law and discuss the ethical points in the Italian context and, in comparison, with the United Kingdom context.

Results: Numerous studies have highlighted that psychiatric patients experience advance directives as an instrument to participate in therapeutic decision-making. Regarding the usefulness of advance directives, Italy and the United Kingdom did not approve deontological rules or laws. The United Nations Commission states that, based on the principles of the Convention on the Rights of Persons with Disabilities, it is necessary to respect the spatient's will, even if it is biased by psychic disorders.

Conclusions: The Convention does not consider advance directives; instead, they just suggest using some support to have the patient regain their competence. In case this is unsuccessful, it is necessary to appoint a substitute decision-maker to express, even in the light of the advance directives, the will that the patient would have expressed if he had been competent.
