NHS organisations across England are rejecting Palantir's patient data platform, according to freedom of information responses reviewed by The Guardian. Health bodies that serve millions of people say the US firm's £330m federated data platform (FDP) offers no clear advantage over existing systems.

Some NHS trusts acknowledge the Palantir system has helped manage waiting lists and improved surgery scheduling. But many others have declined to adopt it or halted trials and reverted to older technology.

A Suffolk trust stated other systems "supercede" the FDP's functionality. Greater Manchester's care board called the Palantir system "duplicative" and "retrograde". Health bodies rejecting the platform span from Gateshead to Truro, The Guardian reports.

The rejections undercut the rationale for the £330m investment in Palantir's data infrastructure across the NHS. The company has faced criticism over its work with immigration authorities and law enforcement, making its role in the UK health system controversial.

The FOI responses do not disclose which alternative systems trusts favour, nor how many NHS organisations have formally rejected the platform versus adopted it. The scale of uptake failure remains unclear from the available data.
