Key takeaways
- A medical directive states your wishes; a medical POA names who decides if you can't.
- Both documents are state-specific in form and execution.
- Hospitals, primary care doctors, and family should all have copies.
- Update after diagnosis, surgery, marriage, divorce, or any change in proxy.
How Olomon thinks about this
Medical directives matter only if they can be found at 2 a.m. Olomon stores executed directives and HIPAA authorizations in your record, with permissioned access for designated proxies, so the right document reaches the right person at the right hospital.
In-depth definition
Medical directives exist so that doctors, hospitals, and your family don't have to guess about your wishes in a crisis. The directive itself is a written statement of what care you would and would not want; a medical POA (sometimes called a healthcare proxy) names the person empowered to interpret and apply your wishes in real time.
Frequently asked questions
Living will is one form of advance directive. Most states use the broader term “advance directive” to encompass living wills, healthcare proxy designations, and instructions like DNR or POLST forms.
