Decision-making capacity and alcohol abuse: clinical and ethical considerations in personal care choices

Requests for competency assessment of elderly patients are among the more common referrals that medical and surgical units make to consultation-liaison psychiatrists. Special considerations arise when impairment in cognition, judgment and function arise in the context of substance abuse. At what point during the admission should the evaluation be made? What if the person does well on the cognitive exam but has shown repeated evidence of self-neglect and need for medical care? What role should the medical profession play in mandating that patients give up harmful addictions? In this paper, we describe a case that illustrates these problems, and discuss some of the clinical and ethical considerations involved in the assessment of personal care competence of patients with alcohol abuse, and provide guidelines for these assessments.
