The NHS has a unique resource - data. David Edmonds asks whether a combination of data and Artificial Intelligence will transform the future of the NHS.

As the NHS tries to exploit its data, the programme raises the danger that data may be flogged off to the private sector at bargain basement prices. Producer Sheila Cook Editor Jasper Corbett
