A healthcare agent is a person designated to make medical decisions on behalf of someone else, typically when that individual is unable to do so due to illness or incapacity. This role is often formalized through a legal document known as a healthcare power of attorney. The healthcare agent is responsible for ensuring that the patient's wishes regarding treatment and care are respected and followed. The healthcare agent may communicate with medical professionals, review treatment options, and make choices about procedures, medications, and end-of-life care. It is important for individuals to choose a trusted person for this role, as they will be making significant decisions during critical times.
