ORDER NOW FOR AN ORIGINAL PAPER ASSIGNMENT;Discussion: Patient’s illness Trajectory Influence

Week 1 discussion There are many factors that affect chronic illness—chronic pain, stigma, social isolation, altered mobility, or fatigue. Utilizing your learning from your readings and the South University Online Library resources, respond to one the following questions: Based on the research, which of these factors have the greatest impact on a patient? Why? Contrast at least two ways the factors would affect a twelve-year-old with the way they would affect a seventy-five-year-old. Consider the twelve-year-old and the seventy-five-year-old have a chronic illness. How does the chronically ill patient’s illness trajectory influence the plan of care? Review Healthypeople.gov website. Discuss how you feel these goals will impact the health of the nation. Briefly discuss how you could incorporate these goals/objectives into your day-to-day nursing practice. Citations should conform to APA guidelines.

Discussion: Patient’s illness Trajectory Influence

When people with life threatening illnesses and their carers ask about prognosis (“How long have I got?”), they are often doing more than simply inquiring about life expectancy. Within this question is another, often unspoken, question about likely patterns of decline (“What will happen?”). One aid to answering both questions may be through the use of typical illness trajectories. Thinking in terms of these trajectories provides a broad timeframe and patterns of probable needs and interactions with health and social services that can, conceptually at least, be mapped out towards death.

Such frameworks may help clinicians plan and deliver appropriate care that integrates active and palliative management. If patients and their carers gain a better understanding by considering illness trajectories this may help them feel in greater control of their situation and empower them to cope with its demands. An important implication for service planners is that different models of care will be appropriate for people with different illness trajectories. We review the main currently described illness trajectories at the end of life and draw out key clinical implications.


We searched our own database of papers, conducted a Medline search, and approached experts for additional published references (further details available from SAM). We also re-examined primary data relating to illness trajectories from our previous studies investigating the palliative care needs of people with advanced lung cancer and heart failure.1

Different trajectories for different diseases

A century ago, death was typically quite sudden, and the leading causes were infections, accidents, and childbirth. Today sudden death is less common, particularly in Western, economically developed, societies. Towards the end of life, most people acquire a serious progressive illness—cardiovascular disease, cancer, and respiratory disorders are the three leading causes—that increasingly interferes with their usual activities until death.

Three distinct illness trajectories have been described so far for people with progressive chronic illnesses (fig 1)26: a trajectory with steady progression and usually a clear terminal phase, mostly cancer; a trajectory (for example, respiratory and heart failure) with gradual decline, punctuated by episodes of acute deterioration and some recovery, with more sudden, seemingly unexpected death; and a trajectory with prolonged gradual decline (typical of frail elderly people or people with dementia).Typical illness trajectories for people with progressive chronic illness.

Summary points

Three typical illness trajectories have been described for patients with progressive chronic illness: cancer, organ failure, and the frail elderly or dementia trajectory

Physical, social, psychological, and spiritual needs of patients and their carers are likely to vary according to the trajectory they are following

Being aware of these trajectories may help clinicians plan care to meet their patient’s multidimensional needs better, and help patients and carers cope with their situation

Different models of care may be necessary that reflect and tackle patients’ different experiences and needs

We now consider each of these three trajectories in more detail.

Trajectory 1: short period of evident decline, typically cancer

This entails a reasonably predictable decline in physical health over a period of weeks, months, or, in some cases, years. This course may be punctuated by the positive or negative effects of palliative oncological treatment. Most weight loss, reduction in performance status, and impaired ability for self care occurs in patients’ last few months. With the trend towards earlier diagnosis and greater openness about discussing prognosis, there is generally time to anticipate palliative needs and plan for end of life care. This trajectory enmeshes well with traditional specialist palliative care services, such as hospices and their associated community palliative care programmes, which concentrate on providing comprehensive services in the last weeks or months of life for people with cancer. Resource constraints on hospices and their community teams, plus their association with dying, can limit their availability and acceptability. Box 1 illustrates this trajectory.

Trajectory 2: long term limitations with intermittent serious episodes

With conditions such as heart failure and chronic obstructive pulmonary disease, patients are usually ill for many months or years with occasional acute, often severe, exacerbations. Deteriorations are generally associated with admission to hospital and intensive treatment. This clinically intuitive trajectory has sharper dips than are revealed by pooling quantitative data concerning activities of daily living.4 Each exacerbation may result in death, and although the patient usually survives many such episodes, a gradual deterioration in health and functional status is typical. The timing of death, however, remains uncertain. In one large study, most patients with advanced heart failure died when expected to live for at least a further six months.8 Many people with end stage heart failure and chronic obstructive pulmonary disease follow this trajectory, but this may not be the case for some other organ system failures. Box 2 illustrates this trajectory.

Trajectory 3: prolonged dwindling

People who escape cancer and organ system failure are likely to die at an older age of either brain failure (such as Alzheimer’s or other dementia) or generalised frailty of multiple body systems.7

This third trajectory is of progressive disability from an already low baseline of cognitive or physical functioning. Such patients may lose weight and functional capacity and then succumb to minor physical events or daily social “hassles” that may in themselves seem trivial but, occurring in combination with declining reserves, can prove fatal.9,10 This trajectory may be cut short by death after an acute event such as a fractured neck of femur or pneumonia. Box 3 illustrates this trajectory.

Clinical implications

Trajectories allow us to appreciate that “doing everything that can be done for a possible cure” may be misdirected.

Optimising quality of life before a timely, dignified, and peaceful death are the primary aims of palliative care. Understanding and considering trajectories may help professionals take on board, at an earlier stage than would otherwise be the case, that progressive deterioration and death are inevitable. Before the terminal stages of a disease, some health professionals may allow the reality of the prognosis to remain unconsidered or unspoken, unwittingly colluding with patients and relatives in fighting death to the bitter end.11 Patients often want palliative oncological treatment even if it is extremely unlikely to benefit them, and doctors usually offer it to maintain hope as well as to treat disease.12 An outlook on death and expectations that are more acquiescent to reality may moderate the “technological imperative,” preventing unnecessary admissions to hospital or aggressive treatments. A realistic dialogue about the illness trajectory between patient, family, and professionals can allow the option of supportive care, focusing on quality of life and symptom control to be grasped earlier and more frequently. Figure 2 illustrates how the idea that palliative care is relevant only to the last few weeks of life is being replaced with the concept that the palliative care approach should be offered increasingly alongside curative treatment, to support people with chronic progressive illnesses over many years.

Box 1: Example of a cancer trajectory

CC, a 51 year old male shop assistant, complained of night sweats, weight loss, and a cough. An x ray initially suggested a diagnosis of tuberculosis, but bronchoscopy and a computed tomography scan revealed an inoperable, non-small cell lung cancer. He was offered and accepted palliative chemotherapy when he had already lost considerable weight (too much to allow him to enter a trial). The chemotherapy may have helped control his breathlessness, but he was subsequently admitted owing to vomiting. Looking back, CC (like several other patients in our study)…
