Understanding how to make decisions about future medical care is a key part of personal planning, especially when it comes to preparing for situations where someone might no longer be able to speak for themselves. Setting out advance decisions for healthcare preferences is one way individuals in the UK can ensure their wishes are known and respected. This process, sometimes referred to as an advance decision to refuse treatment or living will, is not about predicting illness or planning for the worst; rather, it is a sensible, proactive approach to personal autonomy and responsible life management.
While it may be uncomfortable for some, having these conversations and putting preferences in writing can greatly relieve families of the burden of guessing what their loved one would want. It also ensures that medical professionals clearly understand the patient’s choices and are legally safeguarded when they act according to those instructions. In this article, we will explore the purpose, legal framework, practical steps, and emotional considerations involved in making these vital decisions.
An advance decision is a formal way of setting out which medical treatments an individual wishes to refuse in the future, should they become incapable of communicating or making decisions. It allows people to take control of their healthcare by deciding now about treatments they might not want later — such as resuscitation, mechanical ventilation, or artificial nutrition and hydration — if they are ever in a state where they cannot express their preferences.
This type of planning is especially relevant for individuals with progressive conditions such as dementia, motor neurone disease, or terminal cancer. However, it is suitable for anyone, regardless of age or health status, because accidents and sudden illnesses can strike unexpectedly. It is not only for refusing life-saving treatments; it is a declaration of the kind of care you consider consistent with your personal values, ethics, and beliefs.
Advance decisions can bring peace of mind. They enable people to shape the end chapters of their lives in accordance with their values and relieve loved ones from having to make heart-wrenching medical decisions during particularly emotional times. For healthcare practitioners, an advance decision is a clear and direct guide that helps them avoid invasive or unwanted interventions.
In England and Wales, advance decisions are legally binding under the Mental Capacity Act 2005, provided they meet certain criteria. They allow individuals over the age of 18 to refuse specified medical treatment in advance of a time when they may lack the capacity to consent or refuse that treatment.
To be valid, the person must have been mentally competent when they made the decision, must not have been pressured by others, and the decision must relate to a treatment that the person specifies. If the intention is to refuse life-sustaining treatment, the advance decision must be written and signed by the individual, witnessed, and state clearly that the decision applies even if life is at risk.
Different rules apply in Scotland and Northern Ireland. Scotland uses the concept of an advance directive, which is not covered by legislation but is generally respected under common law as long as it is clear and applicable. Northern Ireland also relies on common law, where doctors must consider any clearly expressed wishes, but advance decisions there are not governed by specific statute.
It is important to note that an advance decision can only refuse treatment — it cannot demand treatment. For positive healthcare preferences, such as a request for palliative care, individuals should also consider creating a parallel document such as an advance care plan.
Setting up an advance decision requires careful thought, open conversations, and attention to detail. It is not enough to write down a few general statements. The document needs to be specific and comprehensive to be effective in guiding medical staff. It should also be regularly reviewed and updated to ensure it continues to reflect the individual’s wishes.
The first step usually involves some reflection on the types of treatments or scenarios that are acceptable or unacceptable to the person. This is often influenced by personal values, religious beliefs, cultural views, or past experiences with illness or hospitalisation. For example, someone may feel that living in a permanently unconscious state or being dependent on a feeding tube compromises their quality of life to an unacceptable degree.
Next, it is crucial to consult with medical professionals. A general practitioner or specialist can offer insight into what certain treatments entail and how likely they are to be needed, based on the person’s current health situation or prognosis. They may also help explain medical terminology to ensure truly informed decisions.
Once the preferences are determined, the individual can begin drafting the advance decision. The document should include the person’s full name, date of birth, details of the procedures or treatments being refused, and the specific circumstances under which those refusals apply. It is not necessary to involve a solicitor, but legal advice may be helpful if the individual has complex healthcare choices or family disputes are anticipated.
Where life-sustaining treatments are refused, the law stipulates that the person must sign the document, have their signature witnessed, and include a statement explicitly saying that they understand it could result in their death. This maintains the seriousness of the instruction and protects against ambiguity.
One of the most critical — yet often overlooked — elements of effective advance care planning is ensuring that the document is accessible when needed. It is wise to provide copies to your GP, any health specialist involved in your care, and close family members or friends. Some people also give copies to care homes or keep them in personal medical records.
A central part of this communication strategy involves discussing the content of the advance decision with family, even when that involves potentially uncomfortable conversations. Misunderstandings can arise when relatives are unaware that such instructions exist or disagree with the contents. Being transparent ahead of time can reduce distress and help loved ones support your wishes with clarity and purpose.
To ensure that medical staff honour an advance decision, it must be both valid and applicable at the time it would come into play. That means healthcare providers must be certain that the individual has not withdrawn the decision, made a lasting power of attorney (LPA) for health and welfare that supersedes the decision, or taken any steps that contradict the clause previously made.
Storing a copy in an easily recognisable location, such as a wallet card indicating that an advance decision exists and listing key contacts, can be an additional safeguard in emergencies.
People change, and so do their feelings about what is acceptable when it comes to medical treatment. This is why it is essential to revisit advance decisions periodically. Events such as a new health diagnosis, loss of a spouse, or reaching a new stage in life can shift perspectives on what a dignified end of life looks like.
A periodic review, ideally every couple of years or after major life changes, ensures the document still matches the individual’s current values and state of health. During reviews, it is also a good time to check that the document is accessible and that designated contacts — such as GPs or next of kin — still have copies.
Amendments to an advance decision must be done carefully. If substantial changes are made, it may be safest to withdraw the previous version and write a new, signed, and witnessed document. Again, all key individuals involved should be updated with the most recent version.
Advance decisions do not exist in isolation. They often sit alongside other legal and care planning frameworks. Of particular importance is the lasting power of attorney (LPA) for health and welfare. This legal tool allows an individual to nominate someone they trust to make health-related decisions on their behalf if they lose mental capacity.
When both an advance decision and an LPA exist, precedence typically goes to the one created most recently. If the LPA holder is authorised to make the same decision about refusing treatment, and that LPA was created after the advance decision, then their authority overrides the earlier document.
Advance care planning is another key part of the puzzle. It is a broader, often non-legally binding conversation that covers personal care preferences, spiritual needs, and emotional concerns beyond medical treatment alone. Some advance care plans include preferred places of death, ideas about organ donation, and others’ roles in care.
Collectively, these documents allow individuals to create robust, multi-layered plans that guide their care while reflecting their identity and beliefs. Healthcare providers are becoming increasingly aware of the need to prompt and respect these plans as part of person-centred care.
Creating an advance decision is not only a legal and medical process but also an emotional and ethical journey. It requires individuals to confront their mortality, articulate their values, and consider deeply personal questions such as what they consider a life worth living.
These decisions can be challenging not just for the person making them but also for their family members, who might struggle to come to terms with what seems like a refusal to fight for life. This makes clear communication, explanation, and empathy vital. Professionals such as GPs, palliative care specialists, and counselling services can play an important role in helping families understand these decisions and reduce tensions.
There are also ethical considerations for clinicians. In rare cases, the need to balance the patient’s wishes with the healthcare team’s professional judgement about appropriate care can be difficult. Ethical disputes may arise, particularly when it appears the refusal of treatment conflicts with clinicians’ duty of care. However, if the advance decision is clear, valid, and applicable, the law supports respecting it.
Planning for future healthcare preferences through advance decisions may not be an easy undertaking, but it is one of the most compassionate and empowering steps a person can take. It represents the ultimate expression of autonomy and a deep respect for one’s own dignity in life and death.
While the legal structures and requirements ensure fairness and clarity, the process is, at its core, a personal one. It invites each individual to define what matters most to them in the face of vulnerability and to communicate that clearly and confidently with others.
For families and healthcare professionals alike, the existence of a well-considered advance decision offers a powerful form of guidance and reassurance. It replaces uncertainty with clarity, fear with preparedness, and guesswork with informed consent. Far from being a morbid or pessimistic act, drafting an advance decision is a proactive affirmation of one’s values — a living document that champions choice, self-determination, and peace of mind.
In a healthcare environment increasingly focused on patient-centred care, the role of advance decisions continues to grow in importance. Whether as a standalone measure or part of a broader care planning strategy, it ensures that when the time comes, care is not only clinically appropriate, but also personally meaningful.
