I literally had to be on the ward as much as possible for my mum when she was admitted to advocate for her and provide support and care.
She had no history of dementia and had probably suffered a stroke plus had UTI but one of the doctors misread handwritten notes and read arthritis as Alzheimer’s. They were unaware that she had RA and had been seen by rheumatology in the same hospital for years. Her routine medication was stopped abruptly and she was admitted to a dementia ward where her delirium was ignored despite sudden onset of delusional beliefs and hallucinations.
Her personal care including feeding and fluid intake was shocking. I lived 250 miles away and had primary aged DC with additional needs but the staff expected me to be on the ward all day and every day to keep her calm, order her meals, make sure she ate and drank etc. If I left overnight or, god forbid, was not there at the weekend, when I went back I was made to feel guilty that I had left and would be told that she had had a fall, had been distressed etc (because I hadn’t been there to provide 1:1, only I could calm her when she was distressed).
In my absence, she was given no support to eat, drink, wash or change into clean clothes. When I returned she would have an electronic monitor clipped to her clothes so she didn’t fall out of bed (again) but the nurse call device would be deliberately placed out of her reach. They were aware of acute deterioration and she was supposed to have high calorie meals and fluid intake measured but no support to actually eat or drink was provided by anyone other than me.
It’s very distressing to watch a loved one deteriorate due to lack of basic care whilst in hospital because it exceeds the duties of health care workers but is not the duty of nurses or doctors. It is made worse when you are made to feel that it is not the failure of the health service but a personal failure because it is actually your duty to ensure personal care.
I’d prefer the health service to be honest about what will and won’t be provided so that families, additional insurance, the LA can plan to meet the gap.
OP in your case it does sound like the ‘visitor’ was sticking around waiting for discharge - there can be a wait of hours before the paperwork is completed.
