Background: Internationally, evidence on the support needs of family carers who look after a terminally ill adult in home settings is incomplete. Aim: To illustrate the relevance of 'relevant background worries' in family carers' accounts of caring at home for a dying adult. Design: A qualitative cross-sectional observational study was conducted in England, United Kingdom, in 2011-2013 on the experiences of adult family carers (n = 59) of older dying adults (aged 50+ years) with malignant and/or non-malignant conditions.
