For nursing homes, try the CMS's comparison site. The real link is extremely long, so here's a shortened version: http://tinyurl.com/24yndxl
For hospitals and some other types of facilities, try JCAHO's Quality Check site: http://www.qualitycheck.org/consumer/searchQCR.aspx
or you can also try the CMS hospital comparison site: http://www.hospitalcompare.hhs.gov/
I hope the sites are useful for you.
