A realist synthesis of integrated palliative care and oncology: Synopsis.

内容摘要

Existing evidence demonstrates the benefits of integrated palliative care for people with cancer and their carers, for improved symptom burden, quality of life and appropriate healthcare resource use. The integration of palliative care and oncology has the potential to improve the quality of life and is recommended by international guidelines. However, it is not yet consistent practice. There are many approaches to integration, but it is unclear what works, for whom and in what contexts to achieve the best possible outcomes for people with cancer, carers and healthcare systems. To conduct a realist synthesis to develop a programme theory of how integrated palliative care in cancer works, for whom and in what contexts to achieve improved symptom management and increased quality of life for people with cancer and their carers. To use the programme theory to coproduce, with stakeholders (e.g. patient and public involvement representatives, local, national, international content experts and multidisciplinary practitioners), guidance to inform delivery of best practice and guide future research. Realist review, conducted in accordance with Realist and Meta-narrative Evidence Synthesis: Evolving Standards. Evidence was identified through systematically searching academic databases and through stakeholder engagement. Data were extracted from included articles and were synthesised using a realist logic of analysis to develop explanations of how and why integrated palliative care in oncology works, for whom and in what contexts. One hundred and sixty-four papers from 33 countries were included in the review. Integrated palliative care and oncology could improve people with cancer's outcomes, increase the goal-concordance of care and support workforce well-being. Interventions to support integration should be tailored to the context in which they are delivered. Ensuring the timely delivery of palliative care for people with cancer requires integration that overcomes siloes between oncology, specialist palliative care and primary and community care. The motivation to prioritise the integration of palliative care relies upon all stakeholders first understanding its value. Enriched interdisciplinary collaboration involves developing confidence in their own and their colleagues' skillsets, facilitating co-ordination between care settings and supporting communication within and between teams. Supportive leadership could promote an institutional culture of acceptance of the value of integrating palliative care into oncology management. The realist approach to analysis means that findings are based on our interpretation of the data. To manage the high volume of studies, we limited inclusion to documents published since 2010, using qualitative, mixed or economic methods; therefore, we may have excluded relevant documents. The success of integration is influenced by the ways in which palliative care is understood, prioritised, operationalised and measured within oncology. Through the synthesis of international evidence, this project draws on implementation science to contribute clarity on how integrated palliative care and cancer care can be achieved in practice. Future work should use the implications and recommendations to initiate and optimise palliative care in oncology management. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme as award number NIHR152115. There are currently 3 million people living with cancer in the United Kingdom. To better meet the needs of people living with cancer and their carers, it is recommended that cancer care (oncology) is brought together with palliative care. This is described as ‘integration’. Research shows that palliative care is helpful for people with cancer, especially when they have access to it at the right time. Although there is evidence that people do better when there is integration, it is difficult to do this in practice. We aimed to understand the best ways for palliative care and cancer care to work together. We used a type of literature review called a ‘realist synthesis’ and worked with expert stakeholders. The stakeholders involved 17 people who have experience where palliative care and cancer care work together, and 4 members of the public who have been patients, or carers for patients. We explain how the success of integration is affected by the ways in which palliative care in cancer is understood, prioritised, delivered and measured. We recommend taking action to address the misunderstandings about palliative care both in health care and the wider community. Addressing community understandings of palliative care could enable openness to early integration, alleviating fears through more accurate knowledge of what it does and does not involve. The different professionals involved in making changes need to understand why integration of palliative care with cancer care is important. Teams within and across different care settings need more opportunities to talk to each other and to collaborate when they are caring for people with cancer. They need to involve the person with cancer and their carers in decision-making and assess the overall benefits of integration. Bringing palliative care and oncology together could help to provide care which integrates and supports family, community and society.
