Prob. Code, § 4717

(a) Notwithstanding any other provision of law, within 24 hours of the arrival in the emergency department of a general acute care hospital of a patient who is unconscious or otherwise incapable of communication, the hospital shall make reasonable efforts to contact the patient’s agent, surrogate, or a family member or other person the hospital reasonably believes has the authority to make health care decisions on behalf of the patient. A hospital shall be deemed to have made reasonable efforts, and to have discharged its duty under this section, if it does all of the following:

(1) Examines the personal effects, if any, accompanying the patient and any medical records regarding the patient in its possession, and reviews any verbal or written report made by emergency medical technicians or the police, to identify the name of any agent, surrogate, or a family member or other person the hospital reasonably believes has the authority to make health care decisions on behalf of the patient.

(2) Contacts or attempts to contact any agent, surrogate, or a family member or other person the hospital reasonably believes has the authority to make health care decisions on behalf of the patient, as identified in paragraph (1).

(3) Contacts the Secretary of State directly or indirectly, including by voice mail or facsimile, to inquire whether the patient has registered an advance health care directive with the Advance Health Care Directive Registry, if the hospital finds evidence of the patient’s Advance Health Care Directive Registry identification card either from the patient or from the patient’s family or authorized agent.

(b) The hospital shall document in the patient’s medical record all efforts made to contact any agent, surrogate, or a family member or other person the hospital reasonably believes has the authority to make health care decisions on behalf of the patient.

(c) Application of this section shall be suspended during any period in which the hospital implements its disaster and mass casualty program, or its fire and internal disaster program.
