Glossary: Health Care Directive

A health care directive is a broad term for legal documents that outline your medical care preferences if you are unable to make decisions yourself.

It typically includes documents such as a living will and a healthcare power of attorney, which together define your wishes and who can make decisions on your behalf.

What a health care directive does

A health care directive provides guidance for medical decisions when you cannot communicate your wishes.

It helps:

• ensure your treatment preferences are known
• guide healthcare professionals
• support family members in making decisions

It is often used in situations involving serious illness or incapacity.

Why you need a health care directive

A health care directive ensures that your medical care reflects your preferences.

Without one:

• decisions may be made based on default medical practices
• family members may need to guess your wishes
• disagreements can arise in stressful situations

With a directive in place:

• your wishes are clearly documented
• decisions are easier and more consistent
• your autonomy is preserved

What a health care directive includes

A health care directive often combines multiple documents, such as:

• a living will (treatment preferences)
• a healthcare power of attorney (decision-maker)
• additional instructions depending on jurisdiction

Together, these documents provide both guidance and authority.

What a health care directive does NOT do

A health care directive does not:

• cover financial or legal matters
• replace a last will and testament
• apply while you are able to make your own decisions

It only takes effect when you are unable to communicate or decide.

---

When you need a health care directive

You may need a health care directive if:

• you want control over future medical decisions
• you want to reduce uncertainty for your family
• you are planning ahead for serious illness or aging

It is relevant for adults at any stage of life.

Common mistakes

Some common issues include:

• creating only one part (e.g. living will without a proxy)
• unclear or overly general instructions
• not sharing the documents with others
• not updating them over time

A directive works best when it is complete and communicated.

Country note

The exact structure and terminology vary by country. In some regions, a health care directive is a general term, while in others specific documents (like living wills or proxies) are used separately.
