A new AI model will be trained on a large set of NHS data in hopes of identifying early interventions for patient care.
The generative AI model, called Foresight, is being trained on de-identified data from 57 million people in England as part of a pilot study conducted by University College London (UCL) and King鈥檚 College London (KCL).
De-identified data is data in which personal information has been stripped away, meaning it is not possible to link back to an individual, ensuring privacy.聽Access to the data is within the NHS England Secure Data Environment (SDE), a secure data and research analysis platform.
The model is being trained on routinely collected NHS data such as hospital admissions and Covid-19 vaccination rates. The model could make predictions about health outcomes across all demographics and for rare conditions due to the size of the dataset and its coverage of England鈥檚 population.
The researchers also aim to harness the model to address health inequalities, analysing risks and outcomes at the population level.
UCL Institute of Health Informatics鈥� Dr Chris Tomlinson, who is serving as lead researcher of the study, said: 鈥淎I models are only as good as the data on which they鈥檙e trained. So, if we want a model that can benefit all patients, with all conditions, then the AI needs to have seen that during training.

Foresight comes at a time of increased focus on digital technology to level up healthcare in the UK by the government. The Health Data Research Service, a tool that simplifies access to health data to accelerate research, was launched in April 2025. Partnered with the Wellcome Trust, the government has pledged up to 拢600m to enhance the use of NHS data on a national scale.
UK Health Secretary Wes Streeting has touted the importance of harnessing NHS data since entering office in July 2024. In November, he remarked at a conference that citizens should 鈥渧iew their data in the same way they view their taxes鈥�.
In a statement following Foresight鈥檚 announcement, Streeting said: 鈥淚鈥檓 determined that we use this kind of groundbreaking technology to cut down on unnecessary hospital trips, speed up diagnosis times, and free up staff time.
鈥淎I will be central as we bring our analogue NHS into the digital age to deliver faster and smarter care across the country.鈥�
