I agree that it doesn't really matter Doc CEO or not. We've all heard of the Doc's that have been convicted of fraud, child molestation, mutilation, etc, and conversely CEO's that take great care of their company AND employees. In the end the CEO profits by a profitable company, a happy employee makes for a happy customer = revenue. That being said regardless of ?potential? changeup at the admin level, WCAS has a business that I suspect they want to keep profitable and on the uptick as they are venture capitalist - by nature they want to buy low, sell in 5-7 years for a profit. It serves them no good in any regard to bring in an admin that ruffles the feathers thus decreasing the interest of potential future suitors.
In regards to RVU-heavy, it falls apart in many regards. After being in this game for 10 years as an attending and being a part of a 100% RVU based model, and a 0% based model, I think that the area is probably a 25% RVU'ish +/-, and a PPH multiplier. There are literally a 1000 ways to skin that cat... mostly benefiting those that are making the decisions.
