Population-level health data has the potential to transform research and public health, and the UK is in a unique position thanks to the NHS and its cradle-to-grave records for a population of over 65 million people.

This was shown during the COVID-19 pandemic, where rapid, secure and efficient connection of health information from places such as hospitals, general practices and testing laboratories supported policy makers. This allowed policy decisions to be made quickly around crucial issues, such as lockdowns, shielding and vaccines.

Understanding how to maintain these positive changes and ensure that there is no reversal in the use of data to improve healthcare is at the core of the review.

Patient and public groups with an interest in health data have been consulted throughout the process, including through two public facing workshops. Public and patient voices are embedded in the governance of the review.

About the review

‘Unifying Health Data in the UK’ has been commissioned by the Chief Medical Officer for England and UK Government’s Chief Medical Adviser, Professor Sir Chris Whitty, NHS England’s National Director of Transformation, Dr Timothy Ferris and the UK’s National Statistician Professor Sir Ian Diamond, with the support of the Chief Medical Officers in the devolved nations.

It will be informed by wide consultation and guided by a panel of leading experts from organisations including NHS England, the Office for National Statistics, the UK Health Security Agency, the Department for Health and Social Care, relevant national organisations in Scotland, Wales and Northern Ireland, and others.
