Interesting article. My personal opinion is that in desirable areas with good reimbursement md only practices can work very well. Especially if everybody has a reasonable expectation of what their income should be. By everybody, I mean both doctors and administrators. If either party decides to "maximize profits" or "increase efficiency" or any of the other doublespeak for making more money then that md only practice is going to be in trouble. In areas with poor reimbursement, care team models or the dreaded supervision models will reign. There is really no other choice. In those poor reimbursement areas anesthesia services are seen are a black hole that just sucks in money even if the or as a whole accounts for most of the hospital's profits(which or's usually do).
I think another issue is the fact that there are a lot of areas that just can't recruit enough md's to staff their or's at sustainable salaries. Take my practice for example. I live in one of the worst states for reimbursement. Our payer mix overall is not that great. We still make around mgma average simply because of volume. The hospital pays the crna's and it is strictly a medical direction type of place. We also staff a few surgery centers. Between all of our places we start around 30 or's a day. There is no way we could get 30 md's here to staff those rooms. Both from a salary standpoint and from a recruitment standpoint (its just not that nice of a place to live).
From my standpoint, I miss doing my own cases, I have gotten tired of being 1 to 4 every waking moment of the day , the other day I was doing an interscalene block which was difficult because I also live in one of the fattest states and I got no less than five calls for inductions or preops or whatever else in just a few minutes. It's nuts and I am leaving. I can't wait.
