The NHS has a wealth of data which makes conducting studies across large population groups possible. For example Dexamethasone as a treatment for COVID was identified thanks to having access to a medical history and outcome data across the NHS.
Even so there has not historically been a unified data storage solution as information is split between GPs and individual hospital trusts. Previous attempts to have a single system failed due to complexity and cost overruns. The current solution is the federated data platform (FDP): https://www.england.nhs.uk/digitaltechnology/nhs-federated-data-platform/ which attempts to interoperate with multiple primary data sources to help clinicians access patient records as well as help with resource and service planning.
I assume the Palentir system is involved with providing some sort of AI insights into that data store.



















Are you talking about Vehicle Excise Duty? All cars pay that although at various rates, the more CO2/km attracts higher rates, going far above what the EVs pay.
