What other major medical institutions, besides Johns Hopkins, salary their doctors rather than pay on a fee for service basis?

I tend to be very negative about fee for service medical care. This is part of the reason I lean towards wanting single payer medical care, but even with that it seems in the US we would stick to fee for service.

Recently, I saw a program with someone from Johns Hopkins saying that they salary their doctors. So, it made me wonder…do all the well known medical facilities do this? Mayo, Clevend, etc.?

Feel free to add your opinion about the different payment alternatives.
