Health care agents are individuals who make important health care decisions on behalf of another person, such as a family member or friend who is incapable of making such decisions themselves due to age, illness, or disability. Synonyms for the term "health care agent" include health care proxy, medical proxy, health care surrogate, health care representative, and durable power of attorney for health care. These individuals play a crucial role in ensuring that the wishes and values of the person they represent are respected when it comes to medical treatment options and end-of-life decisions. It is important to have a trusted and reliable health care agent, as their decisions can have a significant impact on the well-being of the person they represent.
