As it is right now, it's ultimately the trusts themselves (as is my understanding), but what safeguards will there (or could there) be in place to keep this data safe.
And what about that data? Do we force any new staff-written applications to create their own MPI etc. or do we let them access the main systems through some kind of API? In which case, that would need creating - and interfacing to a variety of different software is never simple. If it's all to stay on the internal network, then who hosts these apps - and where does that budget come from?
There are a lot of big questions and potential risks here and I'd be very interested to see what these eye-catching initiatives turn out to be. Until I see evidence to the contrary, I remain pessimistic about these being anything but trivial and largely pointless.
If this was a serious effort, why ask the doctors, nurses and other clinical staff to learn to code - and not reach out to the open-source development community and ask them for their help. I'm sure a great many developers have, or know someone, who has used the NHS and would love to have a part in making things better.
