If you're truly disgruntled by medicine, you're not going to solve your problems by starting a private practice---where now, Joe Q. Patient is your boss (ie you need to establish a panel, get credentialed at said small hospitals, 'compete' for the census, etc).
No doubt there's more flexibility in PP . . .but I wouldn't expect to make more money (nor avoid 'burnout') without hustling. There's no such thing as a free lunch in this business.
And your small 25 bed hospitals (which are ridiculously inefficient and costly) will very soon be swallowed up by larger conglomerates . . . rendering you back to where you started from.
You really don't know what you are talking about.
I was burned out, opened my own practice and life is good. It is a viable solution for many people.
Secondly, when you have your own IM/FM outpatient practice, you get to choose which insurance you panel with. Or simply not...
You get to decide if you have hospital privileges or not.
Whether a CCAH is owned by Big Box shop or nor doesn't matter, because they will continue to be on the lower staffing side of things and their med bylaws won't ever change to be aggressive in pushing people out.
In other words, smaller hospitals will continue to be open to independents having privileges and doing their own thing.
The costs of the hospital don't mean anything for the independent doctors who merely practice there with the privileges. Hospital finances, not their problem.
Now, if you pick up hospital privileges, they will typically require you to be paneled with medicare (+/- medicaid) which is fine, so if you get community care patients you see them in the IP, but you don't have to take them on for outpatient primary care follow up. In private practice you can restrict or simply say you are 'capped' for new medicare/medicaid patients.
Personally I made a move from a large metro to such an area. I did recon on several areas of interest and choose the better one for my personal check list. Each of these areas had wait lists for their PCPs. Each of these areas, to my surprise had 1-2 DPC practices with multiple providers! One of these areas was very rural, very middle of nowhere and had very high medicaid/medicare percentage.
Now, the one comment of yours that had truth, you still have to work, and PP takes work that is different from employed jobs, too. Sure, hustle could be the word to use.
