(1) A person found to be gravely disabled or to present a likelihood of serious harm as a result of a behavioral health disorder has a right to refuse antipsychotic medication unless it is determined that the failure to medicate may result in a likelihood of serious harm or substantial deterioration or substantially prolong the length of involuntary commitment and there is no less intrusive course of treatment than medication in the best interest of that person.
(2) The authority shall adopt rules to carry out the purposes of this chapter. These rules shall include:
(a) An attempt to obtain the informed consent of the person prior to administration of antipsychotic medication.
(b) For short-term treatment up to thirty days, the right to refuse antipsychotic medications unless there is an additional concurring medical opinion approving medication by a psychiatrist, physician assistant working with a psychiatrist who is acting as a participating physician as defined in RCW 18.71A.010, psychiatric advanced registered nurse practitioner, or physician or physician assistant in consultation with a mental health professional with prescriptive authority.
(c) For continued treatment beyond thirty days through the hearing on any petition filed under RCW 71.05.217, the right to periodic review of the decision to medicate by the medical director or designee.
(d) Administration of antipsychotic medication in an emergency and review of this decision within twenty-four hours. An emergency exists if the person presents an imminent likelihood of serious harm, and medically acceptable alternatives to administration of antipsychotic medications are not available or are unlikely to be successful; and in the opinion of the physician, physician assistant, or psychiatric advanced registered nurse practitioner, the person's condition constitutes an emergency requiring the treatment be instituted prior to obtaining a second medical opinion.
(e) Documentation in the medical record of the attempt by the physician, physician assistant, or psychiatric advanced registered nurse practitioner to obtain informed consent and the reasons why antipsychotic medication is being administered over the person's objection or lack of consent.
