    A model based on common trajectories of illness and associated care needs would improve the care of people with serious illness in the last phase of life, say Sydney Dy and Joanne Lynn

    Most people believe their lives will be relatively healthy, punctuated by episodes of illness that last no more than a few weeks. On the rare occasions that we think about dying, we imagine short and overwhelming illness in old age. Healthcare systems are designed as if disability and ill health were aberrations, rather than a phase that lasts months or years near the end of our lives, despite the contrary evidence all around us. Because of improvements in sanitation, lifestyle, and medical care, only a small proportion of people in developed countries now die suddenly.1 Most serious chronic illnesses cannot be catered for adequately by traditional hospital and surgical services, and substantial restructuring is needed. The numbers of people living with serious chronic conditions in old age will double in the next two decades in the United States,2 and similar trends will be seen in many other countries.3 Finding sustainable ways to improve comfort and meaning in this last phase of life is therefore a priority.

    Summary points

    • Patients coming to the end of life tend to follow one of three trajectories, with different priorities and needs

    • These trajectories are short decline, exacerbated organ system failure, and long term dementia or frailty

    • Small scale models of care based on these trajectories have helped improve patient centred outcomes

    • Larger scale initiatives to reform care systems are being evaluated in several countries

    Although hospice programmes have been an important and instructive initial response, they do not meet the needs of most patients who are sick enough to die. A minority of people who die with chronic conditions use hospices, and then only for an average of a few weeks.4 In the US, enrolling in a hospice requires acknowledging a prognosis of “less than six months” and forgoing “curative” treatments.5 The inability of doctors to prognosticate with precision and the reticence of patients and doctors to accept these conditions restrict the use of hospice services. This has led to the conclusion, in the US67 and in the United Kingdom,8 that “end of life care” should encompass all people sick enough to die soon, even though some will live in fragile health for some years.

    Many reforms redesign care for specific diseases or within specific settings. However, these approaches do not achieve continuity or comprehensiveness for the increasing numbers of patients with multiple chronic conditions who must use multiple settings of care, with their various methods of payment, and they rarely deal with end of life problems.9 Preferences for care at the end of life are likely to vary more than those for acute injury or illness, so reformers often emphasise allowing patients to choose their course of care.10 Patients' authority to refuse interventions is an important protection for dignity and autonomy, and the ability to shape the course of care is preferable to control by others. Yet, the greatest problem is that important services, such as home support and reliable transfers, often are not readily available or are unreliable. We have found it useful to identify the common patterns of care needs over time while living with fatal illnesses (often called “trajectories”) and to design services to fit them.

    The trajectories

    The clinical course of patients with eventually fatal chronic illness seems to follow three trajectories, described in more detail elsewhere.11112 These trajectories provide a way to describe generalities about large and discernable groups of people, each with different time courses of illness, service needs, priorities for care, and current barriers to reliably high quality care.

    The first trajectory is the maintenance of good function until a short period of relatively predictable decline in the last weeks or months of life. For these patients, planning ahead, aggressive management of symptoms at home, and the concerns of care givers often prevent unnecessary admissions to hospital and other disruptive, undesired, and potentially harmful interventions. This course is typical of common solid cancers in adults, although other diagnoses can have a similar course, and not all cancers fit into this category. Indeed, cancer is becoming a more chronic disease, often presenting as one more comorbidity among the chronic conditions of advanced old age (the third trajectory). About 20% of patients over 65 years in the US follow this trajectory, and they tend to die at a younger age than patients in the other trajectories.1

    The second trajectory is chronic organ system failure, with slow decline punctuated by dramatic exacerbations that often end in sudden death. Chronic heart failure and emphysema are the prototypical illnesses, although any partially treatable serious chronic illness (such as renal failure or cirrhosis) may fall into this group. Optimal management may prevent exacerbations and some of the decline in function. Planning ahead for time limited trials of treatment, for the possibility of sudden dying, and for support of care givers and family increases the continuity and reliability of services. Such planning also makes it less likely that patients undergo unnecessary, burdensome, and costly treatments just before death. People living in this trajectory tend to be intermediate in age between the first and third patterns. Functional status is moderately but not severely limited, and cognitive failure is not prominent. About 25% of deaths in people over 65 in the US fit into this category.1

    The third trajectory is poor long term functional status with slow decline. Very old patients with dementia, frailty, or multiple comorbidities (or a combination of these conditions) fit into this category. Younger patients with, for example, motor neurone disease, neurological complications of AIDS, and strokes can also follow this path. Because unpredictable minor illnesses, such as pneumonia, often cause decline or death, doctors frequently cannot predict survival. Patients usually require months or years of intensive care giving, problem solving, and supportive services, and intensive medical care often does not serve them well. Around 40% of people over 65 in the US follow this path.1

    Of the 15% of deaths not readily classified into these three categories, about half appear to be sudden and the other half have patterns that have not yet been studied.1

    Designing care to match trajectories

    Some system elements are crucially important across all trajectories, including integrating care plans across settings, managing error-free transitions, problem solving, preventing complications and crises, ensuring comfort, planning ahead, and supporting loved ones in bereavement (figure).

    For other elements, patients have different priorities in different trajectories, so reform could build around typical patient situations in each trajectory (table 1). For the first trajectory, excellence requires integrating hospice or similar palliative care support with disease oriented treatment, and responding quickly to changes in symptoms. For the second trajectory, rapidly responsive disease management and mobilising services to the home can reduce exacerbations, prevent hospital admissions, and maximise the quality of the end of life. For the third trajectory, supportive services are crucial, and often need to endure for many years; interventional medical and surgical treatments are much less central to good care.

    Table 2 shows an example of a successful reform project for each of the trajectories; recent systematic reviews913 describe others. Programmes for the frail elderly in other countries, such as Canada,17 and comprehensive programmes for cancer and chronic disease (see box) also show promise for transforming care. These programmes are mostly small and experimental, and they are not yet integrated into the healthcare or payment system. They are also available only to a fraction of patients who would benefit because of restrictive eligibility criteria or unsustained funding.

    Two examples of incorporating these concepts into healthcare systems outside the US are the gold standards framework in the UK and the use of “Esther” paradigmatic patients in health planning in Sweden. The Esther project built care arrangements and prioritised reforms by testing service quality and reliability against prototypical patients, starting with a fictitious but typical complex and frail person that the team called Esther and expanding the concept to consider “Esthers” with colon cancer, with heart failure, and with dementia. This proved to be a useful construct for focusing on each of the populations needing services.

    The gold standards framework incorporates end of life tools and resources into primary care practices, and it has already been adopted by more than 2000 primary care practices (covering a quarter of the UK population).8 This programme asks doctors to identify patients using the “surprise” question, “Would you be surprised if this patient died within the next year?” Patients identified in this way then have different measures of quality than those needing routine acute and preventive care services. Good advance care planning, symptom relief, home support, and other services become priorities and targets for quality improvement for those on the framework registry, whether the patient dies next week or lives with serious illness for a few months or years.

    Customising and reorganising care to match the needs, rhythms, and situations of these three trajectories offers a promising way to improve outcomes for patients sick enough to die. If a community can build a care system that reliably serves the prototypical patient in each trajectory in their area, then almost everyone is guaranteed good care in the last phase of life. That insight simplifies what can seem an overwhelming array of details and possibilities. Such a framework would give direction to planners and managers to organise services, payments, and quality measures. It would also provide a basis for training healthcare workers and planning facilities for this population. It might also help advocacy groups that normally focus on disease specific issues to work together to identify and meet the common needs and priorities of care givers. If a region could deliberate on priorities, set goals, demand excellence, and monitor progress for each trajectory, civic and healthcare leaders and professionals might create a reliable care system for this fragmented and inefficient part of the healthcare picture.
