Politicians as usual
Politicians think things get done by talking about them. So "digital" looks like a logical extension - talking about doing things, but on a computer.
I am sure there are many gains to be had by applying computer power to the NHS, but not in the way politicians want to do it. Healthcare requires people and facilities, both of which are anathema to McKinseyites. Government policies have been delivering overpriced facilities and putting off the very people needed. Privatisation has often been failing where tried because medicine involves a lot of risk and investors don't like it.
Sadly, unless someone finds a way of extracting politicians from the NHS, I can't see things getting better.
