Those are the basic underpinnings that will determine most of the variable compensation across disparate sites. Still, there can be other local factors (ancillary services, specialty support, EMRs, etc.) that come into play. Any practicing hospitalist can quickly discourse on what makes their job unique. And they are probably right—healthcare, like politics, is local.
I’ve run out of room to answer the second part of the question, which addresses the variable pay for physicians at the same site. Check back for that response next month.
