I would suggest checking out your state's department of health web site. They should have information on individual nursing homes via report card and survey results.
In Minnesota we have a senior linkage line that can help consumers, other states might have a similar service.
You could try the local community help line- here we have something called the United Way line.
There is also various websites on line that might be helpful- some may be profit or not- I think of like the caregiver foundation. org or
