Advance Care Planning is a process through which a person considers, discusses and records preferences about future healthcare and decision-making, particularly for circumstances in which they may later be unable to communicate or make decisions. It can include conversations about values, treatment priorities, acceptable burdens, preferred care settings and people the individual wants involved in decisions. Advance Care Planning is broader than completing a single document because it is an ongoing communication process that can be revisited as circumstances change. It is particularly relevant to serious illness, progressive disease and situations in which future loss of decision-making capacity is possible, but it can be considered by adults more generally.
The development of Advance Care Planning reflects increasing emphasis on patient autonomy, shared decision-making and preparation for periods of incapacity. Earlier healthcare systems often relied heavily on decisions made during acute illness, sometimes when patients could no longer express their preferences. Formal planning approaches developed to allow people to communicate wishes in advance and to provide clinicians and families with information about what matters to the person. Contemporary approaches recognise that preferences can change and that documents alone cannot anticipate every clinical scenario. Regular review is therefore important, especially after major changes in health, diagnosis, prognosis, personal circumstances or treatment options.
Advance Care Planning can address general values as well as specific treatments. A person might express preferences concerning priorities such as maintaining independence, remaining at home when feasible, avoiding particular burdens or prioritising comfort under certain circumstances. More specific instructions can address particular future clinical situations where applicable. The usefulness of specificity depends on how foreseeable the situation is and whether the instruction remains consistent with the circumstances at the time. Overly rigid statements can be difficult to apply if the actual situation differs significantly from the scenario imagined when the plan was written. Good planning therefore combines specific preferences where appropriate with broader information about values and goals.
Decision-making capacity is important to Advance Care Planning because the ability to make and communicate decisions can change over time. A person who has capacity can make decisions about current and future care within the limits of applicable law. If capacity is later lost, healthcare professionals may need to consider valid advance decisions, previously expressed preferences and the relevant legal framework. The terminology and legal effect of different documents vary by jurisdiction, so a statement of wishes should not automatically be assumed to have the same legal status as a formally recognised advance decision or appointment of a decision-maker. Clear documentation and professional review can reduce ambiguity.
Conversations with healthcare professionals and family members can make Advance Care Planning more useful because written preferences may not capture the reasoning behind them. Discussing what outcomes the person considers unacceptable or particularly valuable can help others interpret preferences if an unexpected situation arises. Family members should understand that their role is not necessarily to substitute their own preferences for those of the person. Where a legally authorised decision-maker exists, their responsibilities are governed by the applicable legal framework. Advance planning can therefore support rather than replace communication among the person, family and healthcare professionals.
Advance Care Planning is especially relevant to people living with serious or progressive illness because treatment choices can become more complex as disease advances. Discussions may address possible deterioration, emergency treatment, hospital admission, symptom management and preferred care environments. Planning does not mean that deterioration is inevitable within a particular timeframe, nor does it require a person to decline future treatment. A person can state that they would want active treatment under some circumstances while prioritising comfort under others. The process is intended to clarify preferences so that future decisions can better reflect the individual's goals when circumstances become difficult or communication becomes impossible.
Practical implementation requires reliable recording and accessibility of the person's preferences. A plan known only to the individual or stored somewhere clinicians cannot access may have limited value during an emergency. Healthcare systems therefore use various mechanisms to document and communicate relevant decisions, although the exact mechanisms differ by jurisdiction and healthcare setting. Plans should be reviewed after major changes and when the person wishes to alter them. Clinicians must also distinguish between an outdated statement and a current preference, particularly when treatment options or circumstances have changed. Privacy and appropriate information governance remain important because Advance Care Planning contains sensitive personal and healthcare information.
Advance Care Planning should be distinguished from End-of-Life Care because planning can occur long before the final phase of life. It is also distinct from Medical Consent because consent normally concerns a proposed healthcare intervention under current circumstances, whereas Advance Care Planning addresses preferences and decisions concerning possible future circumstances. Advance Care Planning cannot guarantee that every future event will unfold according to the plan, because clinical situations are unpredictable and legal frameworks impose their own requirements. Its principal function is to improve preparedness, preserve the person's voice when possible, support shared understanding and reduce uncertainty about future healthcare choices while respecting the fact that preferences may legitimately change over time.
