The document discusses the challenges facing healthcare in the UK, particularly obesity which costs the NHS £4.2 billion annually. It proposes developing a digital healthcare ecosystem in the West Midlands to help address these challenges in a more sustainable way. This ecosystem would provide local services through an open platform to improve health outcomes for the region's 5.5 million citizens and support the 147,000 staff delivering care. The ecosystem is based on co-creation, collaboration, and open APIs to reflect local priorities in a way that complements national services. Benefits will include supporting quality, innovation, productivity and prevention to help meet financial and demand challenges.
