Substitute Decision-Maker (SDM)

Patients who are very ill and are unable to make treatment decisions will require a close family member or friend to be designated as the Substitute Decision-Maker (SDM), guided by the Health Care Consent Act. The SDM must make decisions based on prior expressed wishes of the patient. If the SDM does not know of a wish applicable in the situation, or it is impossible to follow the wish, the SDM must act in the patient’s best interests. Please ask a member of the health-care team for more information.
