This is a plain English summary of an original research article
In the UK, end of life care is typically put in place for people who are likely to die within the next 12 months. But predictions of the length of time remaining are difficult to make. New research suggests that these predictions are often less accurate than chance alone. The study calls for palliative and end of life care services to be made available without waiting for a prediction of approaching death.
The study pooled previous research into the accuracy of predictions of death, and the problems that arise when predictions are incorrect. The researchers also investigated the types of end of life services available through primary care and in the community.
A lack of warning that someone is dying can have devastating consequences, the study found. Services may not be put in place in time. People may die in pain and away from loved ones; families may feel robbed of time. Those left behind may experience complicated grief for years to come.
Inaccurate predictions caused problems. If someone survived much longer than expected, families could struggle to look after them at home for long periods. People told they only have months to live could lose the hope that sustains them.
The study also described 8 types of end of life services available in primary care and the community. The researchers hope this will help professionals to make the most appropriate referrals.
What’s the issue?
End of life care is generally given in someone’s final weeks or months. This care aims to help people live as well as possible in the last part of their life, and to die with dignity. It does not aim for cure, but to reduce pain and suffering and to ensure the best possible quality of life in the time remaining.
Care to manage distressing symptoms (palliative), can be provided alongside care aimed at cure (curative). It is often wrongly believed, including by health professionals, that palliative care only starts when curative treatment stops. In the UK, end of life care is not usually started until a clinician judges that someone is likely to die in the next few days, weeks, or months.
This study explored how accurate predictions of death are, and whether access to end of life care should depend on a prediction of death. The team also looked at the palliative and end of life care services available in primary care and community settings.
The study pooled evidence from 21 studies, reviews, policy reports, and discussion papers, and from another 317 abstracts. Researchers investigated the accuracy of death predictions and the consequences of inaccurate predictions. They looked at factors that influenced referrals to palliative and end of life care services, and they categorised those available in primary care and in the community.
Predictions of death
The study found that predictions of death varied broadly in their accuracy and were often worse than chance.
A lack of warning that someone is dying could have far-reaching consequences, the study showed. People could feel robbed of time to set their affairs in order, to say their goodbyes, or to arrange the care they prefer. Health and social care services could not always respond effectively in time. This could lead to poor quality care with insufficient pain control and symptom relief to increase the quality of life remaining. People were more likely to be admitted to hospital and receive inappropriate invasive treatments aimed at cure.
But inaccurate predictions could also be harmful. People who survived much longer than predicted could live for years with the constant threat of approaching death. Their family members could come under strain if they were only able to look after their loved one at home for a short time.
Once they had a prediction of death, some people chose to try new curative medicines. Few benefitted from new or experimental treatments; those who did often had small gains only. For some, however, this could mean they died without receiving good palliative care.
Referrals to end of life care services were influenced by whether someone could be looked after at home (family and carers’ needs must be considered) and what systems were available locally. Occasionally, professionals claimed that people had less time left than they believed, to allow access to a ‘better’ service. Some professionals were not aware of all available services.
Carers’ and family members’ observations about changes in a person’s condition were not always taken seriously, meaning that critical information was not included in decisions about end of life care.
Primary care and community services
As a new resource, the researchers grouped primary care and community services (delivered fully or mainly outside of hospitals or hospices) according to how or why they were expected to work.
Different services had different roles. They aimed to:
- increase availability, such as out of hours and home-based services
- address personal needs and provide holistic support, for example through social interactions, financial support, counselling, and complementary therapies
- help people move from one type of care to another (transition care), for instance to manage hospital discharge
- keep the person at the centre of their care, by ensuring their preferences are documented (using both legally binding tools and more flexible decision aids) and by supporting self-management
- provide care according to the phase of someone’s illness, for instance around the time of a diagnosis of serious illness, or in the final weeks or days of life
- take a proactive, ‘whole-system’ approach, such as through advance care planning discussions and electronic systems for recording preferences and sharing data across health services
- improve outcomes, and fulfil someone’s final wishes, through support and training for staff and volunteers, and expanding staff roles
- provide support to informal carers.
Why is this important?
Recent research and policy has a strong focus on supporting dying at home. But there has been little specific discussion about the timing of end of life care.
Palliative and end of life care services are not usually offered until people are identified as being at the end of their lives. Many people do not receive pain relief, symptom control and other support when they need it.
Findings about the inaccuracy of predictions should not discourage professionals from talking about death or timelines, the researchers say. They need to find ways of approaching uncertainty and to give people warning while not robbing them of hope.
The researchers recommend that palliative and end of life care services should not depend so heavily on expectations and conversations about death and dying. They should be offered according to people’s needs. It should not matter how long this care is needed, or whether someone wishes to continue, in parallel, with curative treatments.
Professionals also need more training and awareness of the many kinds of palliative and end of life care services that are available in the community and through primary care. This could help them make more appropriate referrals and put in place more timely care.
The researchers suggest that professionals should have discussions about palliative care far earlier, and not only when someone is dying. Palliative care now includes management of any suffering related to illness. It is needed in many healthcare settings other than in life-limiting illness, death and dying.
Discussions about palliative and end of life services should include:
- patients' physical, psychological, social, spiritual, and practical support needs
- patients' preferences for home care and home care support needs
- patients' preferences for life-saving treatments, including in future when mental capacity might be lacking
- carer needs
- the maximum level of intervention, including whether resuscitation is appropriate
- pain relief and symptom control
- data-sharing preferences which could allow or limit different health professionals’ access to people's notes.
Service providers need a new approach to palliative and end of life care. Many more people need access to holistic care to meet their physical, psychological, social, spiritual, and practical needs. Many aspects of palliative and end of life care represent good care that should be available regardless of whether someone has been judged to be approaching the end of life.
