Be careful if you need to spend a night in high care!

My uncle was treated in a very abusive manner by a nurse on the night staff in high care. He was tied to his bed. He rang for help several times and was ignored. When she finally came he asked for help to get to the toilet. She refused and would not even give him the bottle. He wet himself twice and she would not change the bedding. He is there because of a problem breathing. He was only given oxygen after begging. Is this the way a patient is treated at night when there is no one to watch? Thankfully his doctor arrived before the evidence was hidden and found him tied to a wet bed!
