Many individuals at the end of life are unable to convey their wishes regarding medical treatments. Advance directives (ADs) or living wills (LWs) allow them to crystallise their wishes in a written form so that these can be carried out if the relevant situation arises. In many countries, ADs are legally valid and enforceable; they reduce the use of life-sustaining treatments, which often merely prolong life without improving or even maintaining the quality of life. Such treatment puts a financial burden on the patient’s family, often leading to penury.
