Context: Carers' needs in advanced disease, and specifically in relation to breathlessness, are well evidenced. Publications on educational interventions for carers of patients with advanced disease that focus on symptoms are scarce and absent for breathlessness. Objectives: To establish current education provided by clinicians for carers of patients with breathlessness in advanced disease, views about educating carers about breathlessness, and relevant outcomes for a future randomized controlled trial of an educational intervention for carers.
