Background: Informal carers are essential in enabling discharge home from hospital at end of life and supporting palliative patients at home, but are often ill-prepared for the role. Carers' support needs are rarely considered at discharge. If carers are less able to cope with home care, patient care may suffer and readmission may become more likely. Aim: To investigate the implementation of an evidence-based Carer Support Needs Assessment Tool (CSNAT) intervention to support carers during hospital discharge at end of life.
