The problem is that the NHS needs big tech. There have been a number of issues over the years around medical devices which are known to cause issues, including early deaths because of the unanticipated failure of these devices or other issues associated with implanted medical devices.
The Paterson Inquiry, the Cumberlege Report, the issue of breast implant side effects and this week's story about the Medtronic heart pump that caused early deaths are all things that have happened but where it wasn't possible to track down everyone affected in order to carry out an intervention. Wasn't even possible to get a full picture of issues occurring because of fragmented or poor quality data. Some of the processes for recording use of these devices, and monitoring the outcomes, were poor or non-existent. Some trusts still don't have Electronic Patient Records.
Patient safety relies on timely, complete and accurate collection of data, along with the ability to integrate, monitor and interrogate that data. You can't do this on a spreadsheet; you need big systems to integrate the data coming through from NHS Trusts and other providers. And that means big tech.
The data stored on the system based on Palantir's Federated Data Platform is widely accessible but anonymised so no personal data is held. It's fed by a separate system controlled by the NHS where PII is held.
Patient safety relies on big tech, whether anyone likes it or not.
