Many health, education and social service initiatives aim to implement better multi-agency working between agencies and professionals. But what difference does this sort of organisational change make to those families and children on the receiving end? Making a difference? explores the process and impact of multi-agency working on disabled children with complex health care needs and the families and professionals who support them. Examining in detail the work of six multi-agency services, the report describes the process of multi-agency working, key success factors, and outcomes for professionals, as well as the impact on families in terms of their daily life, well-being, and contact with services and professionals. A concluding chapter summarises key issues and makes recommendations for policy and practice.
