You're talking about something you know precisely nothing about, and that's without your suggestions for how it could work.
NPfIT was to do with providing core fundamentals which could underpin a central record for patients, which could be contributed to and accessed by your care provider as appropriate, including providing some patient access. It was barely to do with providing specific software to any health providers at all.
It was really a gargantuan undertaking, and aside from a couple of the companies taking the **** (iSoft), the real downfall of it was underestimating the complexity and scale of the programme. It was poorly specified, poorly tendered and poorly managed, then when it started to go wrong consultants were brought in to *save* it, which ballooned the cost and if anything stunted the progress.
The deliverables that did come out of it (the spine and choose & book) are actually good steps forward, they just came with a lot of waste. The other partial one was ePrescribing, which is a real key factor in making healthcare more efficient and most importantly significantly safer, as a functional product ePrescribing forms the basis of the company I work for, we have individual trust contracts that are 10s-100s of millions. You are sadly deluded in your estimation of the figures.
