DEMOGRAPHICS OF DEATH IN AUSTRALIA
Australia’s life expectancy in the 21st century has significantly improved for both genders, with the exception of Indigenous Australians3,4. With advancements in medicine and public health (food, water and sanitation), the opportunity to live longer is created, resulting in an increasingly aged population5. The main causes of death in our adult population are related to malignancy and circulatory disorders (acute myocardial infarction, cerebrovascular accidents).6 This leads to an increased incidence of chronic illness in our aged population that will see more people dying from diseases that are chronic, and with multiple pathologies present3,4,6,7, than ever before.
WHY IS THERE A NEED FOR A PALLIATIVE CARE APPROACH?
Worldwide, the incidence and mortality from cancer and chronic disease is expected to increase significantly over the next 20 years8–10, creating more demand for palliative care than ever before5. Cognisant of this changing health pattern, the World Health Organization (WHO) now defines palliative care as
an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual9 (p. 84).
The WHO definition reflects the shifting of palliative care and explicitly identifies that the approach can now begin at the time of diagnosis or at any other point along the illness trajectory, and may be implemented in a range of health care settings10.
THE CHALLENGE FOR NURSES
The nature of the death experience now faced by nurses is significantly shaped by the changing demographics of disease morbidity and mortality, and the increasing age of the Australian population. Nurses will be caring for individuals who will commonly have more than one disease state and/or disability present at the time of death3,4. This co-morbidity of disease results in increased acuity and complexity in the management of symptoms, thus placing additional demands on the nurse’s knowledge and skill mix. The need for nurses to develop a palliative approach inclusive of core knowledge and generic skills, and to transfer this knowledge and skill across acute, community and residential aged care facilities, is paramount6. Ensuring nurses have this capacity will enable individuals and their families to be better managed during their chronic illness and palliation.
The nurse is central in the provision of symptom assessment and management for individuals and their families requiring palliation11–16. Throughout this chapter, we explore specifically those symptoms most commonly identified as having the potential to compound suffering in individuals who are dying.
THE COMMON CLUSTER OF SYMPTOMS
Individuals who experience a chronic, life-threatening illness where curative and restorative outcomes are no longer viable often share a common cluster of symptoms at the end of their life. Evidence is now emerging acknowledging that individuals dying from chronic illnesses may also experience a similar set of symptoms to those experienced by an individual who is dying from cancer6,8,17. The symptoms most commonly identified12,18 are:
This list of symptoms is not exhaustive, and you will encounter many other symptoms experienced by individuals in your nursing practice. However, the symptoms listed are representative of those shared by many people who are facing a life-limiting illness, regardless of the underlying disease, and which may be present in varying degrees. These symptoms have the greatest potential to adversely affect an individual and their family’s quality of life if not treated effectively. An understanding of the symptoms, their cause and the ongoing management will provide you with the skills to intervene appropriately to promote comfort and a quality of life for the individual and their family.
The use of pharmacology in conjunction with non-pharmacological interventions can prove to be invaluable to the individual requiring palliation. Combined, these interventions may promote an improved quality of life for not only the individual experiencing the symptom but also for the family. The important issue to remember here when implementing non-pharmacological interventions is to review their efficacy and interactions with the prescribed medications through discussion with the individual’s medical specialist and/or pharmacist5,19,20.
In case study three, Antonio’s disease process is different again; however, he too will be treated using a palliative approach because his condition is incurable and has complex needs. Antonio is experiencing pain but no longer understands why. The nurse’s aim is to provide interventions that will maintain his level of function and provide his wife and carers with the means to manage his behaviour and symptoms.
CLUSTER OF SYMPTOMS
FATIGUE
Fatigue is the first symptom that is the most frequently encountered symptom individual’s and their families who experience a chronic illness and or who are dying experience, regardless of the underlying cause21–22. No one agreed definition exists for fatigue, but it is generally accepted that it is a subjective feeling of easy tiring, reduced capacity to perform activities, generalised weakness; impaired cognitive function; and emotional lability22–25. Fatigue may also be referred to as asthenia.
In the majority of individuals experiencing a chronic or end-stage illness, fatigue will be experienced, particularly towards the terminal stages. The underlying mechanisms of why fatigue develops in these individuals are not widely understood22, but it is known that the impact of fatigue is significant on the individual’s well-being, relationships with others, and their ability to perform cognitive and physical tasks21,23. Several contributing causes have been identified:
Fatigue is both multifactorial and multidimensional, and the individual’s experience of the symptom is shaped by the degree to which biological, psychological, social and personal factors impact and affect the individual18. Several theories have been proposed to explain the underlying pathophysiology of this symptom21:
The complex and multidimensional nature of this symptom requires a comprehensive physical and mental health assessment to identify potential strategies to support the individual. Nurses have a responsibility, as with all other symptoms requiring palliation, to consider a variety of approaches for implementation and to undertake a holistic evaluation of their effectiveness23. Adoption of this approach into the nurse’s practice has the potential to improve the symptom for the individual.
The use of medications to manage this symptom is often viewed as being limited, although the following have some beneficial effects: corticosteroids, megestrol acetate, and methylphenidate21,22,23.
More commonly, it is the non-pharmacological interventions that are more frequently used as first line management, for example, balancing activity and rest, counselling, adaptation of physical activities, changing medications, education, promotion of sleep, controlling other symptoms21,22,24.
As the end of life nears, increasing fatigue and drowsiness signal a natural decline towards death. It is at this time that no active fatigue management strategies are instituted but rather, the individual and their family are supported holistically by the nurse21.
PAIN
Pain is consistently ranked highly in studies by individuals and their families as the symptom they most fear and find distressing5,26,27. Pain reportedly occurs in 75% of individuals with cancer and 65% of individuals dying from other causes28, and yet, relief of pain and suffering can be achieved for most individuals who are dying26. The palliation of pain is achieved through accurate and continuous assessment undertaken by health professionals initially on presentation, regularly throughout the course of treatment, when changes in the individual’s pain state occurs and by acting as the individual’s advocate27,29.
Collectively, the following two definitions convey the multidimensional nature of pain and therefore, the complexity in managing this symptom. Pain is ‘an unpleasant sensory and emotional experience associated with actual and potential tissue damage, or described in terms of such damage’30(p. 249). Importantly, ‘pain is whatever the person says it is, and existing whenever the person says it does’31(p. 95). The two definitions show how an individual has the capacity to express the impact of their pain in a number of ways: psychologically, behaviourally, psychosocially and/or spiritually27. In particular, the second definition highlights that the symptom of pain is a highly personal and subjective experience for the individual.
Pain arises for individuals who are dying from three sources:
Pain can be classified in several different ways. A brief review of the main categories of pain (acute, chronic) are described below, along with the three main physiological types (somatic, visceral and neuropathic)5,28,32. Some examples accompany the description and are related to individuals receiving palliation. A more detailed examination of pain theory and pathophysiology can be obtained from the recommended reading, listed at the conclusion of the chapter.
Acute pain is the result of recurrent or progressive tissue damage or inflammation, which serves to warn the individual of the injury and is usually a time-limited experience32,33. Pain of this nature has a rapid onset and is usually self-limiting once treatment is initiated, with a predictable outcome5. Acute pain produces the following signs reflecting a sympathetic nervous system response: tachycardia, tachypnoea, hypertension, sweating, pupillary dilatation and pallor5,28.
By contrast, chronic pain results from a chronic pathological process and from repetitive stimulation of the central nervous system28. Chronic pain has an ill-defined onset, with the individual appearing withdrawn and depressed5. This type of pain continues to occur and may increase in its intensity, becoming more severe over time5.
Somatic pain occurs as a result of the activation of nociceptors in cutaneous and deep musculoskeletal tissues that are stimulated by physical factors such as heat, pressure, distension, or chemical reactions such as injury and inflammatory processes32. This pain is often described as a constant, gnawing or aching sensation felt superficially and is mostly localised in its origin5,27,28. Examples may include bone metastases, soft tissue inflammation.
Visceral pain results from the infiltration, compression, distension, or stretching of the thoracic and abdominal viscera, and is often accompanied by other symptoms, such as nausea, vomiting and sweating32. This pain is often described as cramping, wavelike, deep, squeezing or pressure, and is often referred to cutaneous sites remote from the existing lesion5,27,28,32. An example may include liver metastases causing liver capsule distension resulting in referred shoulder tip pain.
Neuropathic pain is a consequence of an injury sustained to the peripheral and/or central nervous systems, where nerve impulses fail to be transmitted and alternate pathways established are painful32. The pain is often described as a numb, radiating, burning sensation, shock-like or electric5,27,28. Examples may include radiation-induced brachial plexopathy, spinal cord compression, cisplatin neuropathy. These descriptions support the nurse’s assessment of how the pain is being felt by the individual, and allow for an accurate determination by the nurse of the type of pain the individual is experiencing (somatic, visceral, neuropathic) and therefore assist in the selection of the most appropriate treatment strategies for the individual.
New pain in an individual dying must be investigated thoroughly, as it may be the sign of infection, fracture, or a neurological problem that may be reversible33.
The primary issue for individuals who are dying is that they are fearful of their pain and the potential impact the pain relief may have on their capacity to engage in normal activities of daily living. Unrelieved pain significantly impacts on all aspects of their quality of life and well-being – their physical, psychological, social and spiritual dimensions27,34. Unresolved pain becomes in itself a disease entity with physical changes occurring to the nervous system and leading to the exacerbation of the individual’s suffering. Furthermore, if pain is not controlled, disruption to the individual’s capacity to engage holistically within their social context potentiates the development of dysfunctional relationships35,36.
For this reason, the nurse has a responsibility to undertake a systematic and comprehensive pain assessment to evaluate the pain needs of the individual, the effect of their responses on their family and to provide advocacy in this process33. This is achieved through: collection of the person’s history; undertaking a physical assessment; utilising a pain scale; determining the level of interference to ‘normal’ function; a description of the pain and its location; an assessment of how their pain feels over a period of time; identification of any behavioural factors affecting their pain and social interaction capacity; determining the effect of pain on their mood, sleep, capacity to cope, goals and finances; and assessing the ongoing impact the suffering has had on their spirituality27,33.
Underpinning the pain management of individuals who are dying is the need for a comprehensive pain assessment that embraces The World Health Organization principles of: by the ladder; by the clock and by mouth37. The principle of by the ladder refers to a graduated step approach to the use of pharmacology, commencing with milder agents in the beginning and leading to the use of opioids when stronger pain is evident. In addition, adjuvant analgesics and non-opioids are used collectively along each step. Adjuvant analgesics are widely used in palliation and have the capacity to
See examples of adjuvant analgesics in Table 17.1. The by the clock principle operates on the premise that pharmacology is administered across a 24-hour time span and not according to an ‘as needed basis’. This is particularly significant for palliative care clients; given the incurable nature of their disease, the impetus causing the pain is not able to be removed or reversed. Utilising the by the clock principle results in a constant flow of analgesia for the individual and prevents peaks and troughs. Where possible, it is preferred that pharmacology be administered by mouth as this is the simplest and least invasive route for the individual and in many instances, the most cost effective27.
