The Web site CiteHealth lets you “Give your health care providers a checkup.” From the site:
CiteHealth is a health care ratings website for consumers to evaluate their health care providers quality in an effort to enable them to make informed decisions about medical care they may be receiving. We accomplish this by providing free reports on health care providers and communities and also by providing a vehicle for patients to convey their experiences and questions to one another. The information contained on each health provider comes from numerous government and commercial sources, direct contact, and from the user base. We currently cover hospitals, nursing homes, dialysis centers, home care agencies, rehabilitation centers, pharmacies, and medical providers.
