BACKGROUND: Co-research is a collaborative approach to research, promoting involvement of individuals with lived experience of a research area as experts by experience. Recently, the importance of co-research within palliative and end of life care (PEoLC) has been highlighted, yet few recommendations exist regarding best practice for involving inclusion health groups (i.e., groups that are socially excluded, typically experiencing multiple disadvantages that contribute to poor health outcomes).

AIMS: To identify and synthesise qualitative literature outlining barriers and facilitators for involving four inclusion health groups (individuals with lived experience of: homelessness, substance use disorder, incarceration or exchanging sex for money) in PEoLC research, from the perspectives of both the researchers and individuals with lived experience.

METHODS: This report is a rapid review with thematic synthesis methodology. Three electronic databases were searched (2012-30th August 2022). Thematic synthesis was used to generate themes across qualitative studies.

RESULTS: Three qualitative studies were eligible for inclusion. Two involved individuals with lived experience of incarceration, and one lived experience of homelessness. No papers outlined best-practice guidance for co-research; all offered reflections on the co-research process. Challenges for involvement included: facilitating appropriate reimbursement; overcoming stigma; fear of tokenism; pre-conceived views and the emotional burden of research. Successes and benefits included: advanced level of insight, a two-way learning opportunity and relatability of lived experience co-researchers.

CONCLUSIONS: This review did not identify any best-practice guidance for co-production of PEoLC research with inclusion health groups. There are few, good quality, qualitative studies offering insight into challenges and facilitators for lived experience co-researcher involvement. Further research and formal policy development is required to produce formal best-practice guidance to support safe, impactful inclusion in PEoLC research. It is important that researchers work together with people who have lived experience of the topic they are researching. Palliative care is specialised medical care for people living with a terminal illness. There is some collaboration between researchers and people with lived experience in palliative and end-of-life care research. However, some groups of people have been excluded. This includes people experiencing homelessness, or people with drug or alcohol addictions. This review aimed to understand what works and what doesn't work when involving four excluded groups in palliative and end-of-life research. These groups were people experiencing homelessness, those who had spent time in prison, people with drug or alcohol disorders, and people who exchanged sex for money.

This review used a shortened methodology, which allowed it to be done quickly. Three online academic databases (Medline, PubMed, PsychINFO) were searched for research projects: three papers were included in the review. No clear guidance for working with these groups was found. Analysis identified themes across papers. Challenges for collaboration included: appropriate payment methods; overcoming stigma; fear of being talked down to,; assumptions made before meeting people, and the potential of becoming upset. Successes and benefits included: better understanding of the research topic, the opportunity to learn from one another, and how research participants could relate to lived experience co-researchers. There are few, good quality papers, but more research is needed to produce guidance to support safe, impactful collaboration.
