Aye, and there can be some pretty nice salaries/perks out there if an FM doc is willing to relocate to the wilderness and work in the ER.By whom? I mean I dunno the ones I know refer to themselves as ER docs. Up until a couple of years ago you could even become a fellow of the ACEP if you worked in EM and had completed an FM residency.
Really interesting write up on the history of EM/FM.
The TLDR is there are a LOT of FM docs working in EM.
