The goal of an advanced directive is to allow you to tell your doctors and health care providers exactly what kind of care you want should you not be able to communicate your wishes. They can, for example, instruct your doctor about both the kind of care you want and the kind of care you don't want. Obviously, the decision to create an advanced directive requires a great deal of thought. Talking your wishes over with your doctor and family members is extremely important. You also need to be aware that the laws governing advanced directives vary from state to state. The National Institute of Health has web page of resources about advanced directives. Many of your questions will be answered there.
