Involving carer advisors in evidence synthesis to improve carers' mental health during end-of-life home care: co-production during COVID-19 remote working.

Family carers are crucial in supporting people nearing the end of life, but their own mental health may often suffer as a consequence. This project summarised what is known about what makes carers' mental health better or worse. Researchers worked with a carer Review Advisory Panel to ensure that project findings were understandable and useful to carers. To report key findings on what made the teamwork between researchers and carers successful; to help improve teamwork in other projects; and to present carers' own recommendations on how to improve their mental health. Nine Review Advisory Panel meetings were held which included four to five carers, a lay Chair and three researchers. Important early preparation included getting to know each other and agreeing how to work together. Key meeting principles were: (1) bringing carer voices to the fore by having a majority of carers and an experienced carer as Chair; (2) highlighting the value placed on meetings by having several researchers attend, including the project lead; (3) flexibility to include carers' own agenda and project changes; and (4) appropriate and prompt carer payment. Meetings had to adapt to online working due to COVID-19. Carers moved from being advisors to taking more initiative and producing their own carer recommendations, which became a main project output. Written reflections by carers and researchers indicated that successful teamwork arose from a shared sense of purpose and gains, mutual commitment and respect, and bridging between researcher and carer perspectives through training, communication, negotiation and compromise. Early preparation helped the group adapt to the challenges of online working. Carer representation on other project committees could have been improved. Project principles enabled good researcher­carer teamwork and produced valuable carer recommendations, but need proper investment in time and resources. Online working can be successful, but needs good face-to-face preparation.
