Developing new health technologies is complicated and often fails to lead to improved patient care. Successfully taking an idea through the necessary research studies and developing it to the point of use in the NHS requires many different areas of expertise. These include; understanding patients' and health professionals' needs, medical and healthcare environments, engineering and digital technologies, design, manufacturing, legal and ethical regulation, business development, how to obtain funding, and many other topics (in our application we refer to these areas the "Innovation Curriculum"). Our Hub covers a region of 1.4 million people in a region that is affected by high levels of disease and health inequalities. Our team includes all regional NHS organisations including GPs, adult and children's hospitals, mental health services and the recently introduced South Yorkshire "Integrated Care System", hundreds of researchers from the University of Sheffield and Sheffield Hallam University, many large and small companies, and patient and public groups. These partners between them have all the necessary expertise and experience in developing new Digital Health technologies to the point of use in the NHS. We will help researchers develop Digital Health technologies by training them in all aspects of the Innovation Curriculum, and by supporting them to work together with the NHS and patients on real ideas and projects. We will hold Citizen's Juries to understand the public and patients' views of Digital Health and to help design our research. We will produce sixty hours of training in Digital Health for researchers, clinicians, patients and the public, freely available and accredited through our partnership with YouTube's authoritative health content programme. We will hold regular "Calls for Ideas" where we support project teams and train them in Digital Health, providing the most promising ideas with initial project funding to help take these towards potential commercialisation.

The LEAP Digital Health Hub is a partnership of the South West's leading Universities, more than 20 supporting companies nationally, many NHS Trusts & Health Boards, 4 social care organisations, the region's Local Authorities, the West of England Academic Health Science Network (AHSN), the award-winning business incubator SETsquared and Health Data Research UK (HDRUK). The 50+ partners that shaped this bid ranged from the research director for a provider of residential care homes, to a chief clinical information officer working in an intensive care unit; from the founder of a femtech startup to the head of the healthcare analytics team for a multinational consulting firm. In workshops through June and July 2022 they told us that Digital Health is as much about design and user experience as health data analysis; it is motivated by patient benefit but must also consider viable business models for industry. All Hub partners will have access to dedicated physical office space in central Bristol alongside the EPSRC Centre for Doctoral Training (CDT) in Digital Health and Care. There, they will train, network and research together across disciplines and sectors. They will engage with partners across the UK- and beyond. Recognising that UK breakthroughs in Digital Health may be equally (or more) impactful abroad, the Hub's new "Global Digital Health Network" links the Hub to Digital Health expertise from the US, China, India, Nigeria and Australia (sections B1.2, B5). The Hub's unique Skills and Knowledge Programme is designed to address the professional training needs of industry, health and social care providers and academia within the two Themes of Transforming Health & Care Beyond the Hospital and Optimising Disease Prediction, Diagnosis & Intervention. This is proposed to be the world's largest Digital Health taught programme. The Hub's Fellowship programme will comprise 5 different schemes to develop future leaders, within not only academia, industry and the health/care sector, but also within the community - as patients or informal carers. The Hub's Research programme focusses on pre-competitive research within the Hub's two thematic areas of Transforming Health and Care Beyond the Hospital and Optimising Disease Prediction, Diagnosis and Intervention. The Hub will add value by surfacing health priorities from its partner health and social care organisations, working with the West of England AHSN and also with Hub members such as Chief Nursing Information Officers, with charities, social care providers, patient and community groups.
