Problem is the care varies even from one ward to another. My father in law was admitted 13 years ago with a renal problem and left in a bed on one ward where he was neglected for weeks, no treatment, no care. As a result he developed bed ulcers on his heels. They didn't notice them until they had become infected and painful.
Then they tranferred him to a renal ward, where the nurses were basically lazy and heartless. The place was filthy: shit and pee everywhere. Visiting was strictly 2pm to 4pm. He was left there in terrible pain for five months while the doctors made no decisions about his care. In the end the infections had spread so far that he had to have both legs amputated above the knee. He spent three weeks on a third ward, for the amputations, where the nurses couldn't have been kinder. The ward was spotless. We could visit when we wanted. For him, those were three happy weeks in six months of utter misery. To his horror, they sent him back to the second ward, but they soon discharged him after that.
He never walked again, and had to spend the rest of his life in a nursing home.
