This was before the NHS.
How long has NHS had her bouncing around in the system then?
Too long, obviously.
Private medical doesn’t make that kind of mistake, if for no other reason than profit margins.
In the beginning, yes. But nobody in the NHS ever bothered to review her case in the years since. The NHS was instituted in the 1950s, I think. So there were a lot of years when she was in custody of the NHS and trying to get some help, and nobody did anything effective to help her.
