See: When Consumer Reports decided to rate the "Best Hospitals" based on their infection rates, while ignoring all kinds of other factors that meant some random rural clinics were awesome, while Mayo, Johns Hopkins, etc. got kicked in the teeth.
As someone working in one of "America's best hospitals" I can confirm that those consumer reports are a complete joke.
Yes that's part of the problem. But in fairness to Consumer Reports, some of the major teaching hospitals were actually terrible at adhering to EBM guidelines for preventing secondary infections. And this was simple stuff like washing hands and sterilizing treatment sites.
