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 can’t. 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, it’s 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 you’re incapacitated.

　　What a health care proxy doesThe primary responsibility of a health care proxy is to advocate for your medical preferences and wishes and ensure they’re 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.

　　Why you need a health care proxyThe 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, it’s 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 a health care proxy uses a living willHow does your health care proxy know your preferences? A living will is the legal document that details how to proceed with medical treatment if you’re 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.

　　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.

　　How to set up a health care proxyEstablishing a health care proxy is a relatively straightforward process:

　　Choose someone you trust. As your representative and medical power of attorney, your proxy should be familiar with your values, beliefs, and medical preferences—and confident in carrying out your wishes. It helps if the person you choose is also comfortable with your family or other loved ones, and capable of making difficult decisions under pressure.Discuss your wishes. Talk to your health care proxy about the medical interventions you would want, your values, and in the case of a more serious condition, your end-of-life wishes. If your wishes change for any reason, be sure to let them know.Create a legal document. Set up a durable power of attorney for health care with your state’s health department or local agency on aging. If you’re a veteran, your local Department of Veterans Affairs office can help. Working with a lawyer will ensure this form meets state requirements, but it’s possible to file it without one. Depending on where you live, you may need to have the document witnessed and notarized.Distribute copies. Be sure to provide copies of the health care proxy document to the person you’ve chosen as your proxy, as well as to your doctor(s), family members, and institutions involved in your medical care. Review your plans regularly and update them as needed. Life happens. Your health can change, and so might your priorities. Regularly review and update your health care proxy document, inform your health care proxy of any changes, and redistribute the revised document to everyone who needs it. If you need or want to change your health care proxy, you can do so at any time simply by filing a new advance directive.Health care proxy checklistThe American Bar Association recommends these parameters when choosing a health care proxy:

　　The bottom lineChoosing 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 you’re 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.
