A. If the declarant appoints an agent in an advance directive, that agent shall have (i) the authority to make health care decisions for the declarant as specified in the advance directive if the declarant is determined to be incapable of making an informed decision and (ii) decision-making priority over any person identified in § 54.1-2986. In no case shall the agent refuse or fail to honor the declarant’s wishes in relation to anatomical gifts or organ, tissue or eye donation. Decisions to restrict visitation of the patient may be made by an agent only if the declarant has expressly included provisions for visitation in his advance directive; such visitation decisions shall be subject to physician orders and policies of the institution to which the declarant is admitted. No person authorized to make decisions for a patient under § 54.1-2986 shall have authority to restrict visitation of the patient, unless such visitation was restricted by a guardian pursuant to the procedures prescribed by § 64.2-2019.1.
B. Any agent or person authorized to make health care decisions pursuant to this article shall (i) undertake a good faith effort to ascertain the risks and benefits of, and alternatives to any proposed health care, (ii) make a good faith effort to ascertain the religious values, basic values, and previously expressed preferences of the patient, and (iii) to the extent possible, base his decisions on the beliefs, values, and preferences of the patient, or if they are unknown, on the patient’s best interests.
