Implementation plan which outlines a roadmap for delivering the commitments made in the Five Year Forward View for Mental Health to people who use services and the public in order to improve care. It prioritises objectives for delivery by 2020/21 and is intended as a blueprint for the changes that NHS staff, other organisations and other parts of the system can make. Key principles of the plan include co-production, working in partnership with local public, private and voluntary sector organisations; early interventions and delivering person-centred care. The plan also gives a clear indication to the public and people who use services what they can expect from the NHS, and when. It also outlines future funding commitments, shows how the workforce requirements will be delivered in these priority areas, and how data and payment will support transparency. Separate sections cover: children and young people’s mental health; perinatal mental health; adult mental health – including community, acute, crisis care and secure care; mental health and justice, and suicide prevention. These individual chapters set out national-level objectives, costs and planning assumptions. Chapters also describe cross-cutting work to help sustain transformation, including testing new models of care and ensuring the health and wellbeing of the NHS workforce.
