Goals of care: a clinical framework for limitation of medical treatment

The development of clear, effective and consistent clinical processes for decision making relating to limitations of medical treatment and documentation of the decisions is an ongoing challenge for all health care systems.

We propose a clinical framework called “goals of care” (GOC). This approach has been introduced and audited in two Australian health services (Royal Hobart Hospital, Tasmanian Health Organisation — South, and Northern Health, Melbourne, Victoria) and is being considered elsewhere. It is influenced by the Physician Orders for Life Sustaining Treatment approach (http://www.polst.org), which is widely used in the United States, coupled with the innovation of assigning each patient episode to one of three treatment categories based on the overall medical treatment goals for that patient at that time.

The three-phase model

Medical decision making is based on determining the GOC for the patient. The patient's situation is assigned to one of three phases of care according to a realistic assessment of the probable outcomes of medical treatment. These phases are clinically defined intentional categories that take heed of, but are quite distinct from, personal goals expressed by patients. Patients can move from one category to another during their illness trajectory. The phases are curative or restorative, palliative, and terminal;1 they are based on phases that were first described in 1990.2 The distinguishing features of each phase are shown in the Box.

The patient assessment is shared with the patient or substitute decisionmaker (SDM) and, if agreed, a GOC plan form is completed and placed in the alerts section of the patient's medical record. A GOC plan is a medical order that clarifies limitations of medical treatment for a present condition; it is not the same as an advance directive, which is usually made by a person, in his or her own “voice”, to inform medical decision making for future episodes of impaired capacity. Goals are revised in the light of changes in medical condition, and appropriate limitations are then documented on a new form. A GOC plan replaces institutional or community-based not-for-resuscitation (NFR) orders.

We documented GOC plans using an original form (Appendix 1), which has been used at Royal Hobart Hospital for the past 3 years. A second, revised form (Appendix 2) is now being introduced more widely in Tasmania, after extensive experience and feedback from clinicians, medical records staff and others. It is simpler and has been modified for use in all settings, including homes and nursing homes.

The original developmental work was done in Hobart after the Royal Hobart Hospital completed a Respecting Patient Choices pilot site project in 2008. This project put a sharp focus on decision making at the end of life across the whole hospital community.

In 2010, a project officer position was created to enable the development of GOC as part of a statewide Healthy Dying Initiative. Based on the principles of health-promoting palliative care, this initiative aimed to empower the whole community, including the health sector, to deal with death in a more direct, open and therefore “healthy” way. Clinical decision making at the end of life was identified as a priority for policy and procedural reform. There were three initial components of the Healthy Dying Initiative: GOC, advance directive redesign and promotion, and encouragement of health-promoting activities relating to death and dying.

The project officer, a non-clinician with extensive experience in community development, helped design the GOC form, develop the policy protocol for its implementation and use, launch the new form, and facilitate initial training in individual hospital units. GOC education was then done jointly with the advance directive work in the wider community in collaboration with a designated officer in the Office of the Chief Health Officer, Department of Health and Human Services, Tasmania.

Audit results

On 1 March 2011, the GOC form and protocol came into effect at Royal Hobart Hospital; it replaced the NFR procedure and form, which were withdrawn with effect from that date.

A retrospective audit of admissions to the Assessment and Planning Unit during August 2011 was undertaken. It showed that GOC forms had been completed for 75% of admitted patients (135/181). A retrospective audit of admissions to the Assessment and Planning Unit during August 2009, before introduction of GOC, showed that NFR forms had been completed for 34% of admitted patients (55/162). (These data were compiled on 28 September 2009 and 26 September 2011, respectively.)

On 6 September 2012, a 1-day point prevalence audit of GOC form completion was undertaken throughout Royal Hobart Hospital, excluding paediatric and day-stay patients. Patient records were reviewed for the presence of a GOC form and/or other relevant documents, such as an advance directive. GOC forms had been completed for 52% of inpatients (148/283) and for 85% of medical inpatients (124/146) who had been admitted that day. For non-medical admissions, a GOC form was completed for 21% of patients (24/112). All 18 patients who subsequently died had dying recognised (GOC category D), and half of them received input from the palliative care service.

A GOC form was implemented at Northern Health on 12 August 2013. It was adapted from the version used at Royal Hobart Hospital, using input from Northern Health clinicians. It was mandated for all adult medical inpatients and for selected surgical patients. A 1-day point prevalence audit of medical patients on 17 November 2013 showed that treatment goals were completed for 81% of patients (82/101).7

Discussion

The purpose of GOC is to ensure that patients who are unlikely to benefit from medical treatment aimed at cure receive care appropriate to their condition and are not subjected to burdensome or futile treatments, particularly cardiopulmonary resuscitation and medical emergency team calls, especially when these are, or may be, contrary to their wishes.

One of the aims of GOC is to change the culture of medical decision making. GOC takes on the challenges of “prognostic paralysis” and the “no-surprises approach”,4 diagnosing dying,8 and prognostic uncertainty.9 There is evidence that many decisions to limit treatment occur in crisis situations, particularly during medical emergency team calls.10 Difficult decisions therefore tend to be made after hours, in the heat of the moment, by clinicians who do not know the patient and without patient or SDM input. GOC prompts treating teams to proactively determine treatment goals at a time when the assessment is likely to be of higher quality and discussions with the patient and family are easier to arrange.

Screening all patients on admission helps identify those who wish to decline treatments that might otherwise be given to them (particularly relevant for treatments that involve blood products). Those who are fit and otherwise well can be screened with the question “are there any treatments that you do not wish to have?”. Others, in light of their past history and current presentation, will require a more in-depth conversation that balances their hopes and expectations with what is medically achievable.

The default position for all patients is the curative or restorative phase, and all appropriate life-prolonging treatment should be deployed as indicated until it is clear that the clinical situation has changed. In other words, the default always favours preservation of life. It has become evident that there is an important subpopulation of patients for whom the goal is cure or restoration but specific limitations of medical treatment apply because of patient wishes or beliefs, and this is specifically articulated in GOC category B on the new Tasmanian form (Appendix 2).

GOC relies on high-quality clinical assessment and good communication skills. Most importantly, it requires clinicians to make a decision. While challenging and contested, differentiation between the palliative and terminal phases is essential. There is a large difference in the medical management and care of a person who has a potential prognosis of a year or two (eg, a patient who has incurable bone metastases due to prostate or breast cancer) and that for a person who may not survive a week.

There are many pertinent observations that can be used to diagnose dying, which can be divided into four principal domains: (i) disease activity; (ii) general functioning; (iii) specific clinical parameters; and (iv) evidence of “death talk” by patients and families. In combination, these observations can help to show whether death is anticipated within the next few days and allow a change of GOC to the terminal phase. Most of the evidence so far suggests that simple non-medical general function parameters are most predictive of impending death.11 For patients in the terminal phase, deployment of tools based on the Liverpool Care Pathway for the Dying Patient (LCP) may be considered. There has been positive experience of an LCP-type tool in Australia,12 despite some negative experiences associated with use of the LCP in the United Kingdom, for which the LCP has, perhaps unfairly, been blamed.13,14

If the diagnosis of dying is made too early and a patient's condition unexpectedly stabilises, he or she will live on provided that the care implemented is proportionate and matched to symptoms, according to principles presented, for example, to the Senate of Canada by the Chief Coroner of Ontario in 1997.15 There are often oscillations in patient condition as the terminal phase approaches, but, once patients are deemed to be in the terminal phase, it is unusual for them to sustainably “upgrade” back to the earlier palliative phase.

The GOC process has proved to be safe, effective and widely acceptable for addressing the limitation of medical treatment in two Australian health services that encompass large acute tertiary hospitals, with aged care and related subacute services. Feedback from clinical staff has been positive, and compliance is variable but rising. So far, there have been no reported major incidents or complaints in which GOC has been causally implicated in an adverse outcome. Comparison with the NFR era is difficult as the population denominator now consists of all admitted patients, not just those deemed unsuitable for resuscitation.

Regular review at each patient encounter is important, with changes to GOC phase and/or treatment limitations as warranted by patient wishes or condition. A clear need was identified at an early stage of the initial GOC project to ensure that limitations determined and documented during an acute admission could be continued during ambulance transfers and within homes, nursing homes and other facilities. An arbitrary 90-day endorsement validity limit was initially stipulated, but this has been removed as it was found to be unnecessary and confusing. General practitioners and community nurses were also keen to see GOC initiated in the community setting, especially for palliative care clients, and this has informed the design of the new Tasmanian form (Appendix 2).

In a recent report, the Australian Commission on Safety and Quality in Health Care acknowledged that it is necessary to attempt to reverse acute clinical deterioration but also to recognise dying and deploy appropriate palliative and terminal care.16

There were extensive discussions about patients or SDMs being required to sign the GOC form to confirm adequate consultation and agreement. The developers have resisted this, arguing that it is a medical form to direct care, and not a patient directive. The emphasis should be on a process of medical assessment and communication that ideally results in clear patient agreement, and/or consensus with the SDM and those who care for and about the person concerned, regarding any limitations of medical treatment.

A requirement for SDMs to sign a GOC form might engender guilt by conveying a false concern about the locus of responsibility for causing death. It should, however, be clear that the doctor signing the form (on behalf of the medical specialist in charge) is taking responsibility for the clinical decision and all appropriate consultation with patients or their agents, as required by ethics and law.17 Ultimately, the decision about signature requirements will lie with individual institutions and/or jurisdictions that start using GOC. Similarly, the distinction between consent and receipt of information will need to be made clear by individual institutions.

We recommend that all health care providers consider replacing their NFR procedures with the GOC approach. GOC is a solid framework for limiting medical treatment that meets the challenge for medical leadership to address the culture of death avoidance in medical decision making.17,18 It also has the potential to help address widespread professional and public concerns about bad dying. Rigorous ongoing “postmarketing” surveillance, auditing and research are, of course, necessary to ensure patient safety and transparency of process.
