The National Programme for IT (NPfIT) is an initiative by the National Health Service (NHS) in England to move towards an electronic care record for patients and to connect 30,000 General practitioners to 300 hospitals, providing secure and audited access to these records by authorised health professionals. The Department of Health agency NHS Connecting for Health (NHS CfH) is responsible for delivering this programme. In due course it is planned that patients will also have access to their records online through a service called HealthSpace. NPfIT is said by the NHS CfH agency to be "the world's biggest civil information technology programme.

The NPfIT is run for the Department of Health by NHS Connecting for Health and their website describes how it is developing at a local level.
There is also a very good website, NHS 23, that gives an independent view of the NPfIT.
