The proxy.

(1) If an incapacitated or developmentally disabled patient has not executed an advance directive, or designated a surrogate to execute an advance directive, or the designated or alternate surrogate is no longer available to make health care decisions, health care decisions may be made for the patient by any of the following individuals, in the following order of priority, if no individual in a prior class is reasonably available, willing, or competent to act:

(a) The judicially appointed guardian of the patient or the guardian advocate of the person having a developmental disability as defined in s. 393.063, who has been authorized to consent to medical treatment, if such guardian has previously been appointed; however, this paragraph shall not be construed to require such appointment before a treatment decision can be made under this subsection;

(b) The patient’s spouse;

(c) An adult child of the patient, or if the patient has more than one adult child, a majority of the adult children who are reasonably available for consultation;

(d) A parent of the patient;

(e) The adult sibling of the patient or, if the patient has more than one sibling, a majority of the adult siblings who are reasonably available for consultation;

(f) An adult relative of the patient who has exhibited special care and concern for the patient and who has maintained regular contact with the patient and who is familiar with the patient’s activities, health, and religious or moral beliefs; or

(g) A close friend of the patient.

(h) A clinical social worker licensed pursuant to chapter 491, or who is a graduate of a court-approved guardianship program. Such a proxy must be selected by the provider’s bioethics committee and must not be employed by the provider. If the provider does not have a bioethics committee, then such a proxy may be chosen through an arrangement with the bioethics committee of another provider. The proxy will be notified that, upon request, the provider shall make available a second physician, not involved in the patient’s care to assist the proxy in evaluating treatment. Decisions to withhold or withdraw life-prolonging procedures will be reviewed by the facility’s bioethics committee. Documentation of efforts to locate proxies from prior classes must be recorded in the patient record.

(2) Any health care decision made under this part must be based on the proxy’s informed consent and on the decision the proxy reasonably believes the patient would have made under the circumstances. If there is no indication of what the patient would have chosen, the proxy may consider the patient’s best interest in deciding that proposed treatments are to be withheld or that treatments currently in effect are to be withdrawn.

(3) Before exercising the incapacitated patient’s rights to select or decline health care, the proxy must comply with the provisions of ss. 765.205 and 765.305, except that a proxy’s decision to withhold or withdraw life-prolonging procedures must be supported by clear and convincing evidence that the decision would have been the one the patient would have chosen had the patient been competent or, if there is no indication of what the patient would have chosen, that the decision is in the patient’s best interest.

(4) Nothing in this section shall be construed to preempt the designation of persons who may consent to the medical care or treatment of minors established pursuant to s. 743.0645.
