(surrogate decision) a decision made with or on behalf of a person who lacks full legal capacity to *consent to or refuse medical treatment. See best interests; Gillick competence; parental responsibility; power of attorney; substituted judgment.
(in England and Wales under the Mental Capacity Act 2005) a legally recognized decision or statement by an adult with *capacity identifying any specific or general treatment the patient does not want in the event that he or she loses capacity. An advance directive or decision (formerly often called a living will) should be informed, made voluntarily, and must be valid and applicable to the medical situation that arises; at the extreme it can constitute an advance refusal of potentially life-saving treatment. It cannot, however, be used to demand future treatment and does not apply as long as the person retains capacity. An advance statement is a more general and less legally binding expression of the person’s values and views on the sort of treatment he or she may or may not wish to undergo. Directives and statements can raise ethical questions: for example, should life-saving treatment refused in advance nevertheless be given if it could restore the patient to a quality of life with which he or she was content before losing capacity.... advance directive, decision, or statement
a delusion in which the patient believes that another person or an animal (usually the patient’s pet) has certain physical symptoms, even though these cannot be objectively verified. The patient with the delusional belief is called the inducer; the person or pet that is allegedly affected is the proxy. Some *monodelusional disorders, such as *delusional infestation, have a prevalence of delusion by proxy of up to 5%. Treatment is usually with *antipsychotics. In some situations it may be necessary to remove the proxy to provide safety from the behaviour associated with the delusion. See also double delusion; folie à deux.... delusion by proxy
