‘Mistrust’ of Palantir may affect NHS research, says health minister

Public confidence in Palantir’s role within the National Health Service has become a significant concern for the UK government, with health innovation minister James Frith warning that mounting distrust of the American defense and technology company could undermine patients’ willingness to participate in NHS data-sharing initiatives. The issue has drawn attention following a notable increase in patients exercising the national data opt-out mechanism, whereby 60,000 individuals withdrew consent for their medical information to be used in research and planning purposes during a two-month period.

Palantir operates the NHS’s federated data platform under a £330 million contract spanning seven years, intended to enhance operational efficiency and care quality. The company and its supporters point to performance metrics, including a reported 110,000 additional surgical operations, a 15% reduction in discharge delays for long-stay patients, and a 6.8% improvement in cancer diagnosis timelines. However, NHS England stated it could not establish causation between these outcomes and Palantir’s technology, and the government’s statistics authority is currently reviewing the data.

Opposition to the contract has intensified among medical professionals and patient advocacy groups, who reference Palantir’s previous work with Israeli military forces and U.S. immigration enforcement agencies. The controversy has been compounded by disclosures that company staff had access to identifiable patient records. Additionally, London’s mayor blocked the Metropolitan Police from executing a £50 million contract with Palantir, citing concerns about alignment with city values, a decision that has prompted the company to pursue legal action.

Frith indicated a potential shift in policy regarding mandatory use of the Palantir-powered platform by NHS trusts, stating that adoption is not required and organizations may select alternative solutions. Members of Parliament, including health committee chair Layla Moran, have urged the government to terminate the contract and change providers rather than extend it. The Department of Health and Social Care maintains that platform adoption has never been compulsory and that trusts have consistently retained the ability to choose alternatives meeting their local requirements.
