The project will be led by Association for Children's Hospices in partnership with Association for Children's Palliative Care, Help the Hospices, National Council for Palliative Care and University of York. The UK wide research will determine the requirements for ensuring that young people with life-limiting and life-threatening conditions have a smooth transition from child to adult palliative, that these transitions are achievable for all, and they are based on good practice embedded within the services.
