Background: Family caregivers are crucial in providing end-of-life care at home. Without their care, it would be difficult for many patients to die at home. In addition to providing care, family caregivers also need support for themselves. Nurses could play an important role in supporting family caregivers, but little is known about if and how they do so. The aim of this study is to explore how nurses currently approach and support family caregivers in end-of-life home care and which factors influence their support of family caregivers.
