Re: The root cause for the NHS is software that won't run on anything but XP.
I find that I have to remember my medical history in order to correct deficiencies in hospital/GP records during treatment. Sometimes a particular record is missing. Occasionally the consultant has merely read the last treatment notes - and made an incorrect assumption about the root cause that necessitated that treatment.
Even those records held on computers are often nothing more than effectively scans of documents - with no correlation. Doctors and consultants don't have time to read much of the relevant history.
My GP once said that the patient soon becomes a relative expert on their own particular condition.
