It depends on the individual home, some are good and some are bad. That said, if it's possible for someone to remain in their own home, an assisted-living facility that still allows them to be independent but get the in-home care they need, or with family then that's usually the best way to go. Nursing homes are depressing places, and the people who go there are very aware that the vast majority only leave when they die. Many don't do well with them at all, but they are the only option for some low-functioning, high-need individuals. The best way to prevent mistreatment of family members who are in such homes is usually to visit them regularly, pay attention to the condition of them and their environment, ask questions, and address any concerns. If someone is just "dumped" in a home then there's a much higher chance that no one will notice if they're not getting quality care.
