All adults, especially elderly adults or those with known health problems, should have medical advance directives, says the Mayo Clinic. As accidents and serious illness can occur at any time, adults should prepare advance medical directive paperwork even if they do not have any identified health conditions.
Medical directives ensure the patient receives his requested medical care if he is incapacitated by an accident or illness, states the Mayo Clinic. There are two types of medical advance directives: a living will and medical power of attorney. A living will outlines specific terms for an incapacitated person's care, while a medical power of attorney names a medical proxy who legally makes medical decisions for the person, explains WebMD.
