The same rules apply to anyone who makes health care decisions on your behalf—a health care agent, a surrogate whose name you gave to your doctor, or a person appointed by a court to make decisions for you. All are required to follow your Health Care Instructions or, if none, your general wishes about treatment, including stopping treatment. If your treatment wishes are not known, the surrogate must try to determine what is in your best interest.

The people providing your health care must follow the decisions of your agent or surrogate unless a requested treatment would be bad medical practice or ineffective in helping you. If this causes disagreement that cannot be worked out, the provider must make a reasonable effort to find another health care provider to take over your treatment.
