The mentally incapacitated patient is frequently encountered in the general medical hospital. Incapacity is the clinical state in which a patient is unable to participate in a meaningful way in medical decisions. Mentally incapacitated patients relinquish the authority, that is the competent patient's right, to choose among professionally acceptable alternative treatments. ⋯ Questions of incapacity or the authority of surrogate decision-makers also arose with comatose, mentally retarded, mentally ill, and physically handicapped patients. While standards to determine capacity remain unclear, a practical approach is to demonstrate that a patient is able to describe the physician's view of the situation and to understand the physician's opinion as to the best intervention. When a patient is deemed to be incapacitated, the physician should turn to family members, whenever possible, to make decisions.
