(a) The Hawaii medical board may establish standards for health care providers to follow in giving information to a patient, or to a patient's guardian or legal surrogate if the patient lacks the capacity to give an informed consent, to ensure that the patient's consent to treatment is an informed consent. The standards shall be consistent with subsection (b) and may include:

(b) The following information shall be supplied to the patient or the patient's guardian or legal surrogate prior to obtaining consent to a proposed medical or surgical treatment or a diagnostic or therapeutic procedure:

(c) On or before January 1, 1984, the Hawaii medical board shall establish standards for health care providers to follow in giving information to a patient or a patient's guardian, to ensure that the patient's consent to the performance of a mastectomy is an informed consent. The standards shall include the substantive content of the information to be given, the manner in which the information is to be given by the health care provider and the manner in which consent is to be given by the patient or the patient's guardian. The substantive content of the information to be given shall include information on the recognized alternative forms of treatment.

(d) Nothing in this section shall require informed consent from a patient or a patient's guardian or legal surrogate when emergency treatment or an emergency procedure is rendered by a health care provider and the obtaining of consent is not reasonably feasible under the circumstances without adversely affecting the condition of the patient's health.

(e) For purposes of this section, “legal surrogate” means an agent designated in a power of attorney for health care or surrogate designated or selected in accordance with chapter 327E.
