Advance care planning is not just about old age. At any age, a medical crisis could leave you too ill to make your own health care decisions. Even if you are not sick now, planning for health care in the future is an important step toward making sure you get the medical care you would want, if you are unable to speak for yourself and doctors and family members are making the decisions for you.

Many Americans face questions about medical treatment but may not be capable of making those decisions, for example, in an emergency or at the end of life. This article will explain the types of decisions that may need to be made in such cases and questions you can think about now so you’re prepared later. It can help you think about who you would want to make decisions for you if you can’t make them yourself. It will also discuss ways you can share your wishes with others. Knowing who you want to make decisions on your behalf and how you would decide might take some of the burden off family and friends.

What Is Advance Care Planning?

Advance care planning involves learning about the types of decisions that might need to be made, considering those decisions ahead of time, and then letting others know—both your family and your health care providers—about your preferences. These preferences are often put into an advance directive, a legal document that goes into effect only if you are incapacitated and unable to speak for yourself. This could be the result of disease or severe injury—no matter how old you are. It helps others know what type of medical care you want.

An advance directive also allows you to express your values and desires related to end-of-life care. You might think of it as a living document—one that you can adjust as your situation changes because of new information or a change in your health.
