An advance directive tells your doctor what kind of care you would like to have if you become unable to make medical decisions (if you are in a coma, for example). A living will is one type of advance directive. It is a written, legal document that describes the kind of medical treatments or life-sustaining treatments you would want if you were seriously or terminally ill. Remember to bring in any existing documents including advance directives and living wills if you would like them included in your medical record.
For more information on advanced directives and living wills, please ask your nurse.
