I was pretty excited to rotate through EM last month, only to get slammed on my first day eval when a senior said, "you are okay.. sometimes you know who should be an EM doc and who shouldn't. you'd be a great doctor, but not a natural EM doctor." I've gotten almost all A's on my rotations, all my attendings and patients loved me, and I like to think myself of a little above avg on medical knowledge. During my month on EM, i saw pts, developed plans, followed up on them, volunteered for procedures, was first to see lab results, and didn't leave until my last patient checked out. What ran through my mind is, who are you, senior resident, to tell others who is made for a specialty or not? My bad, didn't know there had to be a prototype student. Sorry about the venting, but I just feel like a kid who was told by a punk that he wasn't "cool enough" to hang out with a group. So my question is, what characteristics make a student "not fit" for the ED?
