A health care proxy, sometimes known as a health care agent or surrogate, is someone you trust to make medical decisions on your behalf when you canât. Appointing a health care proxy requires that you set up a durable power of attorney for health care.
Although many people name a health care proxy as part of their end-of-life plan, itâs possible (and maybe advisable, depending on your circumstances) to appoint this advocate at any time in your life to ensure your medical preferences, as set out in your living will, are respected and upheld if youâre incapacitated.
The primary responsibility of a health care proxy is to advocate for your medical preferences and wishes and ensure theyâre carried out to the best of their abilities. This duty includes making decisions regarding treatment options for your physical and mental health, surgeries, medications, and (when necessary) end-of-life care. Your proxy may also oversee your medical records.
In addition, a health care proxy acts as a liaison between medical professionals and the people you love, ensuring that medical decisions align with your wishes and best interests.
In other words, this role requires several skills, including the ability to convey your wishes to others; make difficult medical decisions (possibly under pressure); and discuss these choices with professionals and family members.
The need for a health care proxy transcends age, health status, and personal circumstances. Medical emergencies or grave illnesses can strike at any moment, leaving patients unable to communicate their wishes regarding their own medical care.
Appointing a health care proxy legally ensures your preferences are honored while sparing your loved ones the burden of making difficult decisions during an already stressful time. Moreover, having a health care proxy can give you a sense of control and peace of mind, knowing that your expressed values and priorities will guide your care.
Still, itâs important for you and your health care proxy to understand and acknowledge that a crisis, by definition, can be hard to predict. There are limits to how many specifics can be addressed in advance; a lot depends on the skill of the person you choose.
How does your health care proxy know your preferences? A living will is the legal document that details how to proceed with medical treatment if youâre incapacitated. Your living will expresses your preferences regarding life-sustaining and end-of-life procedures, including administering pain medication, resuscitation, tube feeding, organ donation, and more. Many people have strong beliefs or embrace traditions that may not permit certain treatments. A living will spells out those guidelines.
They may sound similar, but a living will and a living trust arenât the same thing (although both can be part of a sound estate plan). A living trust involves creating a legal entity that owns your assets, such as a house, and eliminates the need to have your will probated after you die. A living will, in contrast, is a document that outlines your decisions about health care should you become incapacitated. It provides details about your desire for resuscitation, whether you should be kept alive by artificial means such as a ventilator, and more.
A health care proxy relies on the living will and ensures that your wishes and preferences are carried out. Without a proxy to legally enforce your wishes, some decisions could be overlooked or executed in a way you might not have wanted.
Establishing a health care proxy is a relatively straightforward process:
The American Bar Association recommends these parameters when choosing a health care proxy:

Choosing a health care proxy is a fundamental component of advance care planning that enables you to maintain some control over your medical care, even if youâre injured, ill, or otherwise incapacitated. By designating a trusted agent and articulating your medical preferences, you can help your medical team and family navigate the potential complexities of your care with confidence.
Setting up a health care proxy is also an act of compassion for the people you love. It will help to answer questions that arise and ease their minds so they can focus on your well-being.
