Background: People with a learning disability face health inequality. Those from ethnic minority backgrounds with a learning disability face 'double discrimination' as members of two marginalised groups. Methods: This codesigned review consolidated the evidence on the healthcare experiences of individuals and their carers from ethnic minority backgrounds with a learning disability. Three electronic databases were searched for UK studies from January 1990 to June 2022. Qualitative data from 28 studies were analysed using thematic framework analysis. Findings: There was an overarching theme of 'culture, choice and conflicts of control', which related to the variable preferences for involvement in healthcare decisions. Cultural and individual factors impacted upon experience, with themes relating to 'misunderstanding and mistrust', 'discrimination and stigma', 'isolation', 'feelings of shame and blame', 'burdens of care' and 'carer wellbeing'. Factors associated with healthcare-seeking and care provision are described in the themes 'triangles of care', 'community networks' and 'adaptive communication'. Conclusions: People from ethnic minority backgrounds with learning disability experience complex barriers which influence their healthcare experiences. Recognising and understanding discrimination can be difficult for people with a learning disability. Carers face challenges which influence their own wellbeing. Services need to be responsive to individual cultural contexts, while addressing potential conflicts of control.
