Main article: Palliative care

In medicine, end-of-life care refers to medical care not only of patients in the final hours or days of their lives, but more broadly, medical care of all those with a terminal illness or terminal condition that has become advanced, progressive and incurable.

Regarding cancer care the United States National Cancer Institute writes:

When a patient's health care team determines that the cancer can no longer be controlled, medical testing and cancer treatment often stop. But the patient's care continues. The care focuses on making the patient comfortable. The patient receives medications and treatments to control pain and other symptoms, such as constipation, nausea, and shortness of breath. Some patients remain at home during this time, while others enter a hospital or other facility. Either way, services are available to help patients and their families with the medical, psychological, and spiritual issues surrounding dying. A hospice often provides such services.

The time at the end of life is different for each person. Each individual has unique needs for information and support. The patient's and family's questions and concerns about the end of life should be discussed with the health care team as they arise...

Patients and their family members often want to know how long a person is expected to live. This is a hard question to answer. Factors such as where the cancer is located and whether the patient has other illnesses can affect what will happen. Although doctors may be able to make an estimate based on what they know about the patient, they might be hesitant to do so. Doctors may be concerned about over- or under-estimating the patient's life span. They also might be fearful of instilling false hope or destroying a person's hope. [1] </blockquote> End-of-life care requires a range of decisions, including questions of palliative care, patients' right to self-determination (of treatment, life), medical experimentation, the ethics and efficacy of extraordinary or hazardous medical interventions, and the ethics and efficacy even of continued routine medical interventions. In addition, end-of-life often touches upon rationing and the allocation of resources in hospitals and national medical systems. Such decisions are informed both by technical, medical considerations, economic factors as well as bioethics. In addition, end-of-life treatments are subject to considerations of patient autonomy.

National perspectives Edit

USAEdit

Estimates show that about 27% of Medicare's annual $327 billion budget ($88 billion) goes to care for patients in their final year of life.[2][3]

UK Edit

End of life care has been identified by the UK Department of Health as an area where quality of care has previously been "very variable", and which has not had a high profile in the NHS and social care. To address this, a national end of life care programme was established in 2004 to identify and propagate best practice,[4] and a national strategy document published in 2008.[5][6] The Scottish Government]] has also been published a national strategy.[7][8][9]

In 2006 just over half a million people died in England, about 99% of them adults over the age of 18, and almost two-thirds adults over the age of 75. About three-quarters of deaths could be considered "predictable" and followed a period of chronic illness[10] – for example heart disease, cancer, stroke or dementia. In all, 58% of deaths occurred in an NHS hospital, 18% at home, 17% in residential care homes (most commonly people over the age of 85), and about 4% in hospices.[10] However a majority of people would prefer to die at home or in a hospice, and according to one survey less than 5% would rather die in hospital.[10] A key aim of the strategy therefore is to reduce the needs for dying patients to have to go to hospital and/or to have to stay there; and to improve provision for support and palliative care in the community to make this possible. One study estimated that 40% of the patients who had died in hospital had not had medical needs which required them to be there.[10][11]

In 2010 a survey by the Economist Intelligence Unit commissioned by the Lien Foundation ranked the UK top out of forty countries globally for end of life care.[12][13][14][15]

Care in the final days and hours of lifeEdit

Signs that death may be near Edit

The U.S. Government National Cancer Institute advises that the presence of some of the following signs may indicate that death is approaching:[16]

  • Drowsiness, increased sleep, and/or unresponsiveness (caused by changes in the patient's metabolism).
  • Confusion about time, place, and/or identity of loved ones; restlessness; visions of people and places that are not present; pulling at bed linens or clothing (caused in part by changes in the patient's metabolism).
  • Decreased socialization and withdrawal (caused by decreased oxygen to the brain, decreased blood flow, and mental preparation for dying).
  • Decreased need for food and fluids, and loss of appetite (caused by the body's need to conserve energy and its decreasing ability to use food and fluids properly).
  • Loss of bladder or bowel control (caused by the relaxing of muscles in the pelvic area).
  • Darkened urine or decreased amount of urine (caused by slowing of kidney function and/or decreased fluid intake).
  • Skin becoming cool to the touch, particularly the hands and feet; skin may become bluish in color, especially on the underside of the body (caused by decreased circulation to the extremities).
  • Rattling or gurgling sounds while breathing, which may be loud; breathing that is irregular and shallow; decreased number of breaths per minute; breathing that alternates between rapid and slow (caused by congestion from decreased fluid consumption, a buildup of waste products in the body, and/or a decrease in circulation to the organs).
  • Turning of the head toward a light source (caused by decreasing vision).
  • Increased difficulty controlling pain (caused by progression of the disease).
  • Involuntary movements (called myoclonus), changes in heart rate, and loss of reflexes in the legs and arms are additional signs that the end of life is near.

Symptom management Edit

The following are some of the most common potential problems which can arise in the last days and hours of a patient's life:[17]

  • Agitation
    Delirium, terminal anguish, restlessness (e.g. thrashing, plucking, or twitching). Typically controlled using midazolam,[19] or other benzodiazepines. Symptoms may also sometimes be alleviated by rehydration, which may reduce the effects of some toxic drug metabolites.[20]
  • Respiratory Tract Secretions
    Saliva and other fluids can accumulate in the oropharynx and upper airways when patients become too weak to clear their throats, leading to a characteristic gurgling or rattle-like sound ("death rattle"). Whilst apparently not painful for the patient, the association of the symptom with impending death can create fear and uncertainty for those at the bedside.[20] The secretions may be controlled using drugs such as scopolamine (hyoscine),[19] glycopyrronium,[19] or atropine.[20] Rattle may not be controllable if caused by deeper fluid accumulation in the bronchi or the lungs, such as occurs with pneumonia or some tumours.[20]

Typical care plans, such as those based on the Liverpool Care Pathway for dying patients, will pre-authorise staff to give subcutaneous injections to address such symptoms as soon as they are needed, without needing to take time to seek further authorisation. Such injections are usually the preferred means of delivery, as it may become difficult for patients to swallow or to take pills orally. If repeated medication is needed, a syringe driver (called an infusion pump in the US) is likely to be used, to deliver a steady low dose of medication.

Other symptoms which may occur, and may be mitigable to some extent, include cough, fatigue, fever, and in some cases bleed.[20]
