There are also IM/EM dual residencies now (about 9 programs or so) like the ole Med-Peds folks. I'm very interested in it, too. So much of what you see in the ED, as has already been discussed, is IM related or outright IM (e.g., diabetes left untreated, routine otitis and sinusitis, onychocryptosis etc). Likewise, it's a huge help to have EM training when serving an ultra rural community or a wilderness outpost. It kind of reminds me of fusion cuisine for a career. LoL
