My thoughts on all this sharing your medical data etc.
None of the NHS establishments share their medical data they have of you, with/between other NHS establishments.
Is this not the point of sharing your medical info ???
You all seem to be concerned about malpractice.
Surely if every medical establishment has access to all your medical records !!!???
I have no problems with the treatment side using my information.
I do have problems when less than trustworthy US firms are in the frame to be doing work with this data. It is very easy to deanonymise data if you have reference data.
1984 was a warning, not an instruction manual.
