DP is in hospital every couple of months. He has always pissed himself on the way in and usually there too. He has never been either given a bed bath, nor allowed to shower (because he needs to be under supervision at all times). He has had clean sheets when they're covered with wee, but often not for many hours. Never changed for general filth or blood. He gets quite distressed about the piss a day or so in, as he regains consciousness fully - sometimes he has discharged against advice, just to wash and has been clear about his reasons.
Mind, they also often don't notice when he's having active seizures. So that concerns me more than the lack of hygiene. Last time, they missed 2 while I was shouting for help, because it took 6 people to pin down a screaming woman with dementia to stitch up her face and all the screaming meant noone heard.
It was the same with my late mother. We didn't get on, so I didn't visit very often, but I'd turn up once a week to give her a wash, as she couldn't do it herself and it wasn't done on her long stay surgical wards. I still recall the time her wound burst when I had taken her for a fag - she left a trail of blood and puss from the ground floor to her 4th floor ward, because the flow was unstoppable and huge. She had septicaemia and a variety of other fun, rare infections. And hepatitis... I let everyone know about this mess, including the cleaning team, as I was worried about it. It was still there, drying on over about half a mile of corridor, when I left 4 hours later.
ICU is clean, hygienic and good at looking after patients. Nowhere else is - even HDU was significantly worse, though better than most wards. DP wasn't ever cleaned himself on HDU in a week, but at least his bed was.
I hate hospitals.
