Many patients at the end of life receive care that is inappropriate or futile and, if given the opportunity to discuss their care preferences well ahead of death, may well have chosen to forgo such care.
Advance care planning (ACP) is a process of making decisions about future health care for patients in consultation with clinicians, family members and important others, and to safeguard such decisions if patients were to lose decisional capacity.
Although ACP has existed as an idea for decades, acceptance and operationalisation of ACP within routine practice has been slow, despite evidence of its benefits.
The chief barriers have been social and personal taboos about discussing the dying process, avoidance by medical professionals of responsibility for initiating, coordinating and documenting discussions about ACP, absence of robust and standardised procedures for recording and retrieving ACP documents across multiple care settings, and legal and ethical concerns about the validity of such documents.
For ACP to become part of mainstream patient-centred care, accountable clinicians working in primary care, hospitals and nursing homes must effectively educate colleagues and patients about the purpose and mechanics of ACP, mandate ACP for all eligible patients, document ACP in accessible formats that enable patient wishes to accurately guide clinical management, devise methods for reviewing ACP decisions when clinically appropriate, and evaluate congruence between expressed patient wishes and actual care received.
Public awareness campaigns coupled with implementation of ACP programs sponsored by collaborations between hospital and health services, Medicare locals and residential care facilities will be needed in making system-wide ACP a reality.
Modern medicine saves many people from acute illness who then live longer with chronic illnesses associated with trajectories of declining physical and mental function over months and years, often punctuated by episodes of acute illness or decompensation. Regrettably, considerable suffering as well as dissatisfaction with and overuse of health care result from a mismatch between the needs of chronically ill patients and current practice norms. Advance care planning (ACP) provides a means of ameliorating this mismatch but is yet to be embedded in routine clinical practice or public consciousness.
ACP is a process of making decisions about future health care for patients in consultation with clinicians, family members and important others. It aims to ensure patients’ wishes are respected if they lose decisional capacity. Conceptually, it comprises five sequential phases, from pre-contemplation to action and maintenance (Appendix 1),1 which include completion of a written advance care plan (or advance health directive [AHD], also termed “living will”) and the appointment of a surrogate decisionmaker. Unfortunately, in the past, ACP has often been focused on raising completion rates of AHDs, despite there being no guarantee such documents in themselves improve end-of-life care2 or correspond with future care preferences.3 A better focus is to encourage widespread use of ACP as a process for iteratively identifying and facilitating what patients consider important for a “good death” (such as managing symptoms, avoiding prolonged dying, achieving a sense of control, relieving burdens placed on the family and strengthening relationships) and for informally communicating their future wishes.4
At least 50% of all deaths in Australia each year are clinically expected because of advanced disease.5 In their last year of life, Australians with advanced disease will average eight hospital admissions and incur a 60%–70% chance of dying in hospital.5,6
More than half may be denied adequate opportunity to discuss end-of-life care wishes7 or have them fully enacted.8 Many patients at the end of life undergo futile (of no benefit at all) or inappropriate (harms outweigh potential benefits) interventions.9 Almost a quarter of intensive care beds are occupied by patients receiving potentially inappropriate care,10 while up to a quarter of health budgets are spent on inpatient care during the last 18 months of life without any real prospects of extending overall survival or impacting on quality of life.11 Most complaints received from bereaved family members about hospital treatment relate to end-of-life care, mainly perceived failures of communication and preparedness for death.12 In one study, doctors spent a median time of only 1 minute on do-not-resuscitate discussions with patients after admission.13
Randomised trials of ACP are few and report mixed results. The sentinel trial, SUPPORT (Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments), which used nurse facilitators over 2 years to undertake discussions with seriously ill hospitalised patients and families and document their preferences, showed no improvement in patient control over their treatment.14 However, a more recent trial of ACP showed improved patient and family satisfaction and alleviation of anxiety in relatives of hospitalised patients.15 Observational studies have shown similar findings.16 Other randomised trials17 and before-and-after studies18 involving nursing home residents have shown 40% to 80% reductions in rates of hospitalisation and up to threefold increases in palliative care referrals resulting from advance care directives. Experience with ACP in the aged care sector in Victoria has shown that less than 3% of residents in aged care facilities approached about ACP declined it, and 90% of those who completed ACP died in the facility while receiving palliation rather than in hospital, compared with only 50% of those who had not completed ACP.19 Use of ACP invokes earlier initiation of more appropriate palliative care, which improves patient symptoms and mood, reduces undesired use of invasive interventions and life-sustaining treatments, lowers the likelihood of inhospital death, prolongs life of higher quality and decreases costs.20-22
Regardless of potential benefits, ACP uptake in Australia has been slow, despite widespread professional and public endorsement coupled with supporting legislation in every state and territory. However, many hospitals and nursing homes are now implementing ACP programs, most along the lines of the Respecting Patient Choices program initiated at Austin Hospital in 2002.23 Factors inhibiting universal adoption of ACP are several:
Reluctance to acknowledge impending mortality: Reflecting societal norms, most individuals, including clinicians, find it difficult to think and talk about dying.
Perceived irrelevance: Many patients may perceive themselves as being “too healthy”, hope (often unrealistically) for medical technology to prolong healthy life, regard future events as a matter of fate, or consider their wishes are already known to doctors and family.24
Issues of timing: Intuitive prognostications of clinicians can be inaccurate, with formal prediction tools offering limited assistance.25 Consequently, “curative intent” remains the focus, with initiation of ACP often occurring too late, leading to rushed care decisions and suboptimal outcomes.
Diffusion of responsibility: The role of initiating and coordinating ACP, which must encompass all patient needs — clinical, emotional and spiritual — must be accepted by someone. Patients often wait for doctors to broach the subject, while clinicians wait for patients or family members to do so. General practitioners wait for a signal from specialists that may never come if multiple specialists are involved, with no one taking charge overall.26
Limited clinician time, skill and remuneration: The pressure of clinical work, a focus on managing acute medical problems and the absence of suitable training and remuneration discourages clinicians from dedicating time to ACP.
Limitations of surrogate decisionmakers: The views of proxies and patients are often discordant,27 or there may be conflicts between family members. Surrogate decisionmakers may not want to assume sole responsibility, and subsequent guilt, for terminating life-sustaining measures.
Ambiguous, inconstant or poorly recorded wishes: Patient preferences can change over time, are often based on wrong or insufficient information, or are documented in vague, incomplete terms on forms not easily retrieved when needed. Because of this lack of clarity at the time of decision making, doctors and surrogates may disregard or feel incapable of enacting expressed wishes, especially if legal or ethical concerns persist around patients’ decisional capacity at the time ACP documents were written or altered.
Differing perceptions of ACP: Many people feel intimidated by what they perceive as legally binding and irrevocable AHDs which arise from ACP. Others equate ACP with palliative care, which they assume indicates imminent death due to a rapidly terminal illness. Finally, some link ACP with euthanasia or assisted suicide, which has seen doctors in the United States who discuss ACP with patients being caricatured as “death panels”.28
Given these challenges, no single strategy will achieve the transition of patients and their proxies from pre-contemplation to action in ACP.29 The most effective and systematic, yet personalised, approach comprises structured, iterative conversations about values and preferences for end-of-life care led by trained, trusted and paid facilitators (who may include nurses and social workers as well as doctors). Such conversations occur over several visits, actively involve properly informed surrogates, and are supported by oral, written and videorecorded information. In these interactions, an advance care plan or a medical enduring power of attorney may serve as more versatile media for ACP than a static AHD.30
Contemplation of ACP by patients and their clinicians often starts with recent serious illness or major surgery, worsening symptoms and functional decline, or experience with ACP involving significant others.31 Lay texts32 and public engagement campaigns such as the Conversation Project in the US (www.theconversationproject.org) and Dying Matters Coalition in the United Kingdom (www.dyingmatters.org) encourage people to have “kitchen table” end-of-life care discussions with family members and then with their doctors. Furthering these conversations requires proactive intervention by clinicians who are highly knowledgeable of the clinical profile of individual patients and the burdens of disease-specific treatment options, able to identify triggers for opportunistic discussions about ACP, cognisant of both physical and non-physical domains of health, and trained in communication and shared decision-making skills.
While the timing of ACP must be sensitive to patients’ readiness to enter into such conversations, a pragmatic three-step guide for clinicians33 is to consider ACP if:
“No” is the answer to this question: “In light of all you know about this patient, would you be surprised if he/she was to die within the next 6 to 12 months?”;
the patient’s general health is poor (eg, limitations in self-care, multiple hospitalisations); and
disease-specific indicators portend a poor prognosis (eg, advanced organ failure, dementia, disabling neurological conditions, progressive malignancies).
Specific triggers for ACP discussion might include: new diagnoses of life-limiting conditions; severe, irreversible deterioration in the patient’s health status; loss of response to, or complications from, disease-specific treatments; unrealistic expectations or requests for care by the patient or their family; or an expressed desire of the patient or their family to discuss ACP.
Initial reactions of patients and family to ACP can be negative, but responses usually improve as issues are clarified and resolved. Patient comfort in discussing end-of-life care is facilitated by a stepped approach and use of facilitative language (Appendix 2). The first step is a values discussion aimed at defining values, goals and preferences for care in general (advance statement of preferences or wishes) and only later moving to more binding decisions about specific forms of care under specific circumstances (advance decisions). A key task is ascertaining which patient wants what information at this particular time, while respecting preferences for silence. Identifying a surrogate decisionmaker and involving them in discussions around foreseeable events should also occur at an early stage. Patients and surrogates should be reassured that responsibility for terminating life-sustaining measures will be shared between clinicians (as technical medical experts) and themselves (as experts on patients’ values and preferences).
Further tips for ensuring successful ACP conversations are listed in Box 1,34 and useful resources, including ACP document templates, are available in various texts35 and from several websites: Advance Care Planning Australia (http://advancecareplanning.org.au); National Health Service Improving Quality (http://www.endoflifecare.nhs.uk/care-pathway/step-2-assessment,-care-planning-and-review/preferred-priorities-for-care.aspx); and the Conversation Project (www.theconversationproject.org). Legitimate concerns about ACP can be mitigated by instituting appropriate safeguards (Box 2).
In embedding ACP into routine practice, all health care organisations (general practices, hospitals, residential care facilities) need to become “conversation ready”; that is, committed to systematically eliciting, documenting and enacting patients’ care preferences.36 System-wide processes (Box 3) are needed that will consistently:
invite all eligible patients to consider ACP for future care relevant to their stage of illness;
provide competent assistance by trained and accountable personnel; and
ensure written plans (however documented) are
Given their longstanding, trusted relationships with patients, GPs are probably best placed for timely ACP, but they need to be supported in this task by medical specialists, senior nurses and allied health professionals. Legal clarification is required regarding the need for advance care plans or AHDs to comply with specific forms, their transferability between jurisdictions, their scope in covering all future treatment decisions, and the enforceability of oral plans or directives. In all Australian jurisdictions, competent patients or surrogate decisionmakers cannot demand treatment that clinicians believe to be futile, including enteral or intravenous nutrition and hydration. There are no reports of Australian or UK courts overturning a carefully considered decision to withhold treatment doctors deemed to be futile.37
The goals of ACP are indisputable and its benefits are becoming evident. If ACP is to become a mainstream clinical activity, health care services and professionals must effectively educate themselves and their patients about its purpose. They must take practical steps to implement auditable ACP systems in routine practice, document ACP in accessible formats that enables patient wishes to accurately guide clinical management, review ACP decisions when clinically required, and evaluate the effects of ACP on clinical outcomes and the fulfilment of patients’ wishes.

3 System-wide strategies for embedding advance care planning (ACP) into routine care
Initiate conversations about ACP when admitting frequently hospitalised patients, formulating acute resuscitation plans or care pathways for chronically ill patients and caring for patients transferred from or to residential care facilities.
Place clinicians skilled in ACP in all units with sizeable numbers of chronically ill patients (general and geriatric medicine, oncology, cardiac and respiratory), tasking them with identifying and counselling suitable patients and imparting ACP skills to other staff.
Routinely initiate ACP conversations between senior nurses and patients and their proxies following admission, after any major change in clinical status and at yearly intervals, or more frequently depending on change in clinical status.
Require facility-affiliated general practitioners and geriatricians, working with senior nurses, to undertake ACP training and information sessions and implement and audit ACP processes according to best practice.
Require hospital and health services, Medicare locals and residential care facilities to generate and use area-wide ACP document templates that are standardised, simple, patient-friendly and readily downloadable at the point of care. File copies of completed advance care plans and/or AHDs in a consistent manner, flag them on all patient records (including patient-controlled electronic health records) and ensure they are able to be rapidly retrieved, preferably via a centralised electronic registry.
Ensure all clinicians, especially doctors, case managers and social workers, undergo training in ACP and appropriate communication skills using simulation techniques, role-play, scenario analyses and computer-based decision aids.
Display brochures and texts that introduce ACP (such as Planning your future care, available at www.endoflifecareforadults.nhs.uk) in clinics and interview rooms and on noticeboards.
