I only came across one who wasnt getting enough and I think that was probably cause she refused to go into the old folks home. where she certainly needed to be (she was left on her toilet all day after being put there with her breakfst in the morning, and stuck there till someone could help her back to bed at night, she couldnt move around at all).
I have sometimes been shocked by the treatment of the elderly even in hospital. A woman who had just been admitted to the bed next to mine couldn't find her walking stick. It had got lost or mislaid during admission. She couldn't get the nurses to help, and one said that it was there next to her bed. I had a good look, and it wasn't. I had to help her to the loo as there seemed to be no other help available.
Then when I was in an isolation room I heard someone calling for help from the loo next door. I found an elderly woman sitting on the loo, having somehow managed to get the door open, gasping that she couldn't breathe. I called out to the nurses who were sitting at their station down the corridor, but I think I ended up having to walk down the corridor (I was supposed to stay in my room!) to get someone. Eventually a young nurse came up and said to the woman in a chiding, patronising voice "What have you done?"
She gave her oxygen (it was after all a
respiratory ward) and put her back to bed - without her underwear or incontinence pad, which were left in the corner of the toilet for half an hour, an hour, perhaps more, despite my drawing attention to them (again having to walk down the corridor), but the nurses just sat there and muttered to each other. Numerous people used the loo in the meantime.
I vowed then to avoid hospital at all costs when I was old, and soon decided to avoid them altogether - at least as an inpatient - whenever possible.
That said, there WERE good staff in that hospital. Most of the nurses were very good. But that particular group - goodness knows what was wrong with them.
