Background: Gypsy, Traveller and Roma communities are known to experience health inequalities. There has been little focus on palliative care in these communities despite the well-recognised inequalities of access to palliative care in other minority ethnic groups. Methods: Systematic review and thematic analysis of the current evidence concerning palliative care experiences, views and needs of Gypsy, Traveller and Roma communities. Medline, Embase, Emcare, CINAHL, PsycINFO, Web of Science, Scopus, AMED, Global Health, Psychological and Behavioural Sciences Collection and BNI were searched up to November 2020, alongside author and citation searching. NHS England, Hospice UK, National Audit Office and OpenGrey were searched as grey literature sources. Gough’s ‘Weight of Evidence’ framework was used for quality appraisal. Results: Thirteen papers from eight studies were included in the synthesis. Although there was variation between communities, three overarching and inter-related themes were identified. 1) Strong family and community values include a preference for healthcare to be provided from within the community, duty to demonstrate respect by attending the bedside and illness as a community problem with decision-making extending beyond the patient. 2) Distinct health beliefs regarding superstitions around illness, personal care, death rituals and bereavement. 3) Practical barriers to non-community healthcare provision include communication difficulties, limited awareness of and access to services, tensions between patients and healthcare professionals and lack of training in delivering culturally appropriate care. Conclusion: A wide range of factors influence Gypsy, Traveller and Roma community access to palliative care. Community diversity requires sensitive and highly individualised approaches to patient care.
