I have read all this and find it terrifying. It seems that if you are a patient in hospital in the UK, you need a friend or relative beside you much of the time, to protect you. It makes me think I'd top myself rather than end up old and vulnerable and in hospital.
I now live in Australia. I can't say our hospitals are better for old people, because I simply don't know. When my husband had his knee replacements in a public hospital here, in his mid 60s, most of the care was fine. Just one nurse was nasty and inefficient, so I wrote a letter of complaint. The complaint was acted upon - they'd had a few verbal complaints about this same nurse, and my letter was the final straw that gave them the right to force her into retraining.
Cleanliness is OK in our local hospital: they have been top of the cleanliness league after official inspections. I only know this because a close friend is the hospital librarian. Incidently, they get lots of Doctors from the UK here as immigrants, or here for a year or two. They usually say their working conditions are better here, which is another point of view about UK hospitals, I suppose. If the staff are unhappy, perhaps it reflects on patient care?
I don't really like to compare, and I hate it when I read bad things about my home country, which I miss dreadfully, but it looks to me that things are going to have to change or there will be a revolt.
