People with intellectual disabilities (ID) experience marked health inequalities. This is attributable, at least in part, to suboptimal healthcare communication with health care practitioners (HCPs) whereby patients with ID and HCPs struggle to understand each other. Companions who attend healthcare appointments with patients with ID can support the communicative exchange between patient and HCP, but their involvement can have unintended consequences. This article uses Conversation Analysis (CA) to analyse video-recorded data from primary care health checks involving 24 patients with ID. This method shows that companions use their linguistic and experiential resources to intervene as ‘brokers’ to address real or potential threats to mutual understanding between patients with ID and HCPs. Their interventions can fill in the gaps in knowledge and understanding of the other parties, but also run the risk of deskilling the others in the interaction, by relieving them of the obligation to address communication breakdown directly themselves.
