In 1973 my late husbands grandma had to go into a nursing home as she had developed Dementia, she was 85 years of age. Her daughter my husband's mum was caring for her at home and had POA but she developed cancer and could no longer take care of her mum. She had to sell her mum's house to pay for her care.
When we used to visit her in the nursing home, she was always wearing someone else's clothes and the problems we had with the staff were terrible. Because my husband's mum was now dying of cancer my husband took over POA and reported the nursing home. The person that ran the home and some of the staff were sacked and another person took over the running of it. Everything was then perfect, because the new manager knew that my husband and I were keeping checks on everything, they looked after his grandma and she was happy. She lived three years after being admitted to the nursing home.
After all these years, things have not improved and unless you are watching out for your loved ones, then the people without relatives have to fend for themselves in many cases (not all I may add). That is why some relatives are hiding secret cameras so they can keep a check on their loved ones.
As long as I am able to look after myself I am happy but if the time ever comes that I need extra help, I will pay for at home care. But I dread going into a nursing home. I am in my mid 80's now.
