Advance Medical Directive (AMD)
An Advance Medical Directive (AMD) is a legal document you sign in advance to inform your doctor that you do not want any life-sustaining treatment to be used to prolong your life in the event that you become terminally ill, unconscious or when where death is imminent.
The AMD can be made by any person, aged 21 years and above, and of sound mind. The AMD form is a legal document which must be completed and signed in the presence of two witnesses before it is returned to the Registrar of AMDs. The patient’s doctor must be one of the two witnesses, while the other witness must be at least 21 years old. In addition, both witnesses must not have any vested interests in the patient’s death.
