An advance directive lets someone document their own medical wishes ahead of time, so that if they can't speak for themselves, their care still reflects what they wanted — not a guess. This isn't legal advice; requirements vary by state/country.
The two components
Living will — a written statement of what kinds of treatment someone does or doesn't want in specific situations (e.g. resuscitation, ventilation, feeding tubes) if they're terminally ill or permanently unconscious. It speaks for them when they can't speak for themselves.
Healthcare proxy / healthcare power of attorney — names a specific person to make medical decisions on their behalf, for situations the living will doesn't explicitly cover. Medicine rarely fits neatly into the scenarios a form anticipates, so having a trusted decision-maker matters as much as the document itself.
Most complete advance care plans include both, often combined into a single form depending on the state/country.
Why this is worth doing before it's needed
Without an advance directive, family members are often left guessing — or disagreeing — about what their loved one would have wanted, at the worst possible time to be figuring it out. Having it in writing, discussed in advance, removes a huge amount of both uncertainty and potential conflict between family members.
Where the conversation should happen first
The document matters less than the conversation behind it. Before (or alongside) filling out a form, it's worth actually asking: what matters most to them if their health declined seriously — independence, comfort, time, being at home? Those answers make forms easier to fill out and give whoever holds healthcare proxy the context to make judgment calls the form doesn't cover.
Keep it accessible, not just signed
A directive that exists but that no one can find in an emergency doesn't function as one. Once it's signed:
- Give copies to the healthcare proxy and to primary doctors.
- Bring it (or a note of where it is) to hospital admissions.
- Store it somewhere every caregiver in the family can find it — tracked in Care Keep's legal documents section, for example, rather than only in a physical filing cabinet at one person's house.
Revisit it periodically
Wishes can change as health changes. It's worth reviewing an advance directive after any major diagnosis or significant decline, not treating it as a one-time task.
