Advance directives: living wills, proxies, medical orders and planning outcomes
On this page
Advance directives record healthcare wishes or designate a person to help decide when someone cannot make the relevant decisions. Advance care planning is the broader process of discussing goals and preparing for future care. A completed document is one part of that process.[1]
Documents and discussions serve different purposes
| Category | Meaning | Boundary |
|---|---|---|
| Living will | Records treatment wishes for specified future circumstances | Different from naming a decision maker[1] |
| Healthcare power of attorney | Names a proxy for healthcare decisions | Rules and activation requirements differ[1][2] |
| POLST | Portable medical orders for serious illness or advanced frailty | Completed with and signed by a clinician[4] |
| Planning conversation | Explores wishes, goals and options | Does not automatically create a valid legal document[2] |
Choosing a proxy involves communication
NIA’s proxy worksheet asks whether a person can talk comfortably with the proposed proxy about wishes and priorities. The role is not simply a name entered on a form. Discuss what matters, likely situations and how to contact the care team. The worksheet helps prepare that conversation; it does not determine legal eligibility or guarantee that a proxy will predict every future preference. Check the locally applicable appointment requirements and make sure the person understands the role.[3]
Healthcare planning differs from financial estate planning
The MedlinePlus encyclopedia distinguishes a living will from a last will and testament and explains that healthcare proxy authority does not give general financial authority. It also notes that state laws govern living wills. Different documents may be packaged together, but their purposes remain distinct. Ask which document records treatment wishes and which appoints the healthcare decision maker. This US overview is not a finding that an online form, witness arrangement or signature is valid in every jurisdiction.[2]
A portable order is not a form for everyone
National POLST describes its forms as medical orders for people with serious illness or advanced frailty. The provider should discuss diagnosis, prognosis, options and goals, then complete and sign the order. It can address resuscitation, hospitalization and intensive treatment. A healthy person ordinarily needs advance planning rather than a POLST form. Local programs use different names and signature requirements. The categories should be clarified with the care team instead of assuming every planning document gives the same emergency instructions.[4]
Review whether the recorded wishes still fit
Preferences can change. The Office of the Public Guardian’s England-and-Wales explanation advises keeping an advance refusal up to date. Conduct clearly inconsistent with an old refusal, or a later lasting power of attorney covering that treatment, can affect its validity. Discuss a changed plan with the relevant professionals rather than assuming that the oldest document always governs. This is a local framework, not a worldwide form-validity rule.[9]
Consider what happens if the chosen agent cannot act
New York’s official health-care proxy booklet allows an alternate agent when the first agent is unavailable, unable or unwilling to act. Discuss the role with the people you propose and check the applicable form and local requirements. A backup appointment is different from assuming that any relative can take over automatically.[10]
Evidence & uncertainty
Planning can improve communication and documentation, but those are different outcomes from receiving the care a person wants. A 2025 cluster trial increased recorded preferences while also increasing potentially burdensome end-of-life care in its specified decedent subgroup.[5][6]

Is a living will the same as naming a medical decision maker?
Selected-source overview · Independent review pending. Read the evidence context.
No. A living will records treatment wishes; a healthcare power of attorney names a proxy. They can complement each other but perform different roles. Ask which locally valid document serves each purpose.[1]

Does a healthcare proxy automatically manage finances?

No. The encyclopedia separates healthcare authority from general financial or legal authority. Estate and financial arrangements need their own applicable documents.[2]

Should every healthy adult fill out a POLST independently?
Selected-source overview · Independent review pending. Read the evidence context.
No. National POLST describes a clinician-completed medical order for serious illness or advanced frailty. A healthy person should distinguish advance planning from that medical-order process.[4]

What should be discussed with a proposed proxy?
Selected-source overview · Independent review pending. Read the evidence context.
Discuss wishes, priorities and whether the person is comfortable speaking about them. NIA’s worksheet supports preparing this conversation; it does not substitute for the local appointment requirements.[3]

Does more planning paperwork prove better end-of-life care?
Selected-source overview · Independent review pending. Read the evidence context.
No. Documentation and later care are different outcomes. The cluster trial improved recorded preferences but had mixed downstream findings. That does not make a form useless or determine what care any individual wants.[6]

Is completing the document enough if nobody knows where it is?
Selected-source overview · Independent review pending. Read the evidence context.
Share accessible copies with the proxy and care team, using the service’s process. NIA recommends safe storage and giving copies to relevant people. Keeping wishes available is part of planning.[7][8]

Why review an advance refusal when my wishes or arrangements change?
Selected-source overview · Independent review pending. Read the evidence context.
England-and-Wales guidance advises keeping it current. Changed wishes or a later lasting power of attorney covering the same treatment can affect the old refusal; discuss updates under the relevant local framework.[9]

A better conversation is not the same as a guaranteed endpoint
A 2022 systematic review examined 132 randomized trials published through May 2021. It found stronger evidence for proximal outcomes such as communication than for many later patient outcomes. Only twelve trials assessed end-of-life care consistent with preferences, and three reported improvement. Different interventions, settings and measurements limit a single summary. This dated review does not establish that planning lacks value; it shows why recording a form, improving discussion and achieving goal-concordant care should be evaluated separately.[5]
Later trial findings make the outcome distinction concrete
The SHARING Choices cluster trial compared a multicomponent primary-care program with usual care for adults aged sixty-five and older. New preferences were recorded for 12.0% versus 6.6% of eligible patients without baseline documentation. Potentially burdensome care in the final six months of life was assessed among Maryland residents with serious illness who died within eighteen months of entry. It occurred in 28.8% versus 20.9% (adjusted odds ratio 1.40; 95% confidence interval 1.08–1.81). Coded potentially burdensome care did not establish whether each person’s care was unwanted. These outcomes challenge the assumption that more documentation alone guarantees better care.[6]
Documents need to be available and current
NIA advises giving copies of completed living-will documents to the proxy and healthcare provider and storing them safely. Its caregiver guidance also recommends sharing the proxy’s contact details with the people providing care. A form left somewhere inaccessible may be less useful during a crisis. Discuss how the service stores and finds documents and what to do after changes. Availability supports communication; it does not guarantee a future treatment outcome or replace the clinical discussion.[7][8]
