Washington Revised Code Title 70. Public Health and Safety § 70.122.060. Procedures by physician--Health care facility or personnel may refuse to participate

(1) Prior to the withholding or withdrawal of life-sustaining treatment from a qualified patient pursuant to the directive, the attending physician shall make a reasonable effort to determine that the directive complies with RCW 70.122.030 and, if the patient is capable of making health care decisions, that the directive and all steps proposed by the attending physician to be undertaken are currently in accord with the desires of the qualified patient.

(2) The attending physician or health facility shall inform a patient or patient's authorized representative of the existence of any policy or practice that would preclude the honoring of the patient's directive at the time the physician or facility becomes aware of the existence of such a directive.  If the patient, after being informed of such policy or directive, chooses to retain the physician or facility, the physician or facility with the patient or the patient's representative shall prepare a written plan to be filed with the patient's directive that sets forth the physician's or facilities' intended actions should the patient's medical status change so that the directive would become operative.  The physician or facility under this subsection has no obligation to honor the patient's directive if they have complied with the requirements of this subsection, including compliance with the written plan required under this subsection.

(3) The directive shall be conclusively presumed, unless revoked, to be the directions of the patient regarding the withholding or withdrawal of life-sustaining treatment.  No physician, health facility, or health personnel acting in good faith with the directive or in accordance with the written plan in subsection (2) of this section shall be criminally or civilly liable for failing to effectuate the directive of the qualified patient pursuant to this subsection.

(4) No nurse, physician, or other health care practitioner may be required by law or contract in any circumstances to participate in the withholding or withdrawal of life-sustaining treatment if such person objects to so doing.  No person may be discriminated against in employment or professional privileges because of the person's participation or refusal to participate in the withholding or withdrawal of life-sustaining treatment.
