While their sample size is much greater than doctor-rating websites, the methodology suffers from the same selection bias. Yet Press-Gainey insists that the methodology is rigorously tested and scientifically valid. Intuitively, I can't imagine how random phone surveys would generate equivalent data as self-directed mail-in or web-based responses for the reasons stated in the above post. As my knowledge of statistics is sorely lacking, I would welcome any scientific defense of the Press-Gainey methodology - until then, I still feel their variable survey methodology is inherently biased in favor of hospitals using random phone surveys.

It allowed me to discover that my medical diploma from McGill University in Montreal came from "une boite de cracker jack." I now have a site called IrateMds.com about scifi doctors. I worry that I may be an evil Cylon or a Sith lord. I find doctor ratings sites very useful.
