Here are my thoughts about this, after going through the job-hunt process a few times. This is geared toward new grads mostly:
The thing that makes a private-practice group successful or not is
how much they are paid by insurers. This is the blended unit value. (see this:
ASA Survey Results: Commercial Fees Paid for Anesthesia Services – 2021 | ASA Monitor | American Society of Anesthesiologists). (caveat, there is also the hospital stipend)
How do you think it is that some groups have great work-life balance and still get paid very well, while others work a ton and get paid so-so? It because of
how much they are paid by insurers. All this discussion about "how much you should be earning" doesn't mean much, because if you set up shop as a new solo anesthesiologist working with your surgeon buddy, and you go to UHC or BCBS and ask for $100/unit contract, they'll give you $25/unit while telling you to go f*ck yourself.
You might say-- "but locums jobs are paying $400/hr! Thats the market value!" Not really, these jobs are more highly reimbursed for a reason-- theyre short-term and involve travelling constantly. Not a fair comparison to a stable job in one location for years.
A good group has spent significant time (years) and resources battling with insurers to get paid more. They have some type of leverage that is giving them the upper hand in these negotiations. Same thing with hospital stipend. The group has a relationship with the hospital that they have leveraged in order to get paid more. This involves meetings with admin, collecting data to show value, etc etc
So in theory, at least, this is what you are buying-in to. The leveraged relationships.
Not all buy-ins are fair, of course. You have to decide for yourself. Especially in the era of the No-suprises act, and impatient hospital admins, you should do your homework to see if you think the terms of the partner position will be the same when you finally 'make it'.
Ask the group "how long have you had this contract? how often is it negotiated? what is keeping a large national group from sweeping in? what is your blended unit value from insurers not including and including hospital stipend? Have the insurers made any noise about reducing reimbursements in the face of the No suprises act? What are the groups plans to address this?"
Hope this helps
