If you are planning ahead, you can make an advance healthcare directive. This arrangement lets you set out your wishes regarding medical and healthcare treatment in case you are unable to make these decisions in the future. Importantly, it lets you write down any treatment you do not want.
You can appoint someone you know and trust as your designated healthcare representative. They will act on your behalf regarding the decisions in your advance healthcare directive. A designated healthcare representative has the power to advise on and interpret your wishes. They can agree to, or refuse treatment on your behalf, based on your advance healthcare directive.
Doctors and other healthcare professionals must consult your advance healthcare directive if you lose the ability to make a treatment decision.
