I am English, but I live in Scotland. The hospitals up here are SO much better than down South. I've never had an issue.
But the English hospitals I've experienced have been dire :
I was hospitalised for a miscarriage and stayed in overnight. Didn't get fed once.
When I had my babies mistakes were made - a pair of scissors swaddled in with my daughter, for eg.
My uncle had a brain haemorrhage and was temporarily blind - they would put his food next to him and not tell him it was there - so my Dad had to go in at every meal time to feed him.
My Dad is always in and out of hospital with infections (he's elderly now) - his notes say which antibiotics he is resistant to, but they never read the notes and give him the wrong meds - EVERY SINGLE TIME.
Simple, common sense things, that a non medical person (like me) can see are wrong, and could so easily be rectified.
Also the system is so clunky, with Departments not talking to each other - for example, the Discharge team are supposed to connect with the Carers when my Dad goes home (to reinstate the care) - they never remember to do it. And then when the Ambulance driver delivers him home, they see there's no care and just dump him anyway - no water or phone given - just dumped in a chair and left.
In fairness, they have brought my Dad back from the brink many times, so there is that, but that really reinforces the ageing population theory, as he would be dead by now without medical intervention. Add to that, that his quality of life is rubbish, and you have to wonder whether that's a good thing. He would say so (of course), but my sibling and I are run ragged (and have been for 5 years now), with spinning all of the plates that are required to care for a fully grown man of 22 stone, who behaves like a toddler most of the time.
