In recent years, the competency of patients to refuse life-sustaining treatment has been widely discussed. Generally, competence has been recognized to be a legal concept, holding that the patient is presumed competent unless a court declares the person incompetent and designates a guardian. It has been noted, however, that clinical medical practice often diverges markedly from this standard. Some authors have suggested that in many cases the implicit medical presumption may be that many persons, particularly the aged, are presumed incompetent to refuse treatment until they demonstrate to their physician's satisfaction that they are competent. This gap between legal theory and medical practice presents numerous difficulties to both legal and medical professionals seeking to accommodate the competing values of patient self-determination and best interests.
This paper will present and discuss a case exemplifying a particular problem that can arise in the competency evaluation process.
