I haven't worked in an ED in 6 years.
This definitely is a part of it. But that's also a very misguided resentment. In the days before full time EPs (not that long ago, 1960's, 1970's) those docs that now b**tch about getting called for an admission, not only still had to do those admissions, they had to pull shifts in the ED at night, regardless of specialty. Many of you millenials have forgotten this, or are not aware, but prior to when board certified EPs were the norm and common, every doc on staff, whether surgeon, dermatologist, GP or psychiatrist, had to cover the ED shifts at night.
So, in reality, the existence of full time, residency-trained, board certified EPs, which didn't exist prior to 1970 (Univ Cincinnati, 1st EM residency, 1970) greatly, greatly, reduce the workload of those physicians who now resent the false impression that Emergency Physicians increase their workload. So, in reality, doctors who resent "emergency physicians increasing their workload" are actually ignorant of (or have forgotten) the fact that those full time, board certified ER docs, greatly reduce their workload. In fact, prior to this era, the norm, regardless of what specialty, was to work a busy clinic at least 40 hrs per week (+/- OR time), and share group and ER call after hours, AND rotate through the ER to cover actual ED night shifts, regardless of specialty and regardless of havnig any competence to do so. Peds, psych, derm, path, it didn't matter. If you were on staff, you had to share in the coverage, because "ER doctors" as we know them today, didn't exist. Imagine how much it would suck, to have to go back to that. I'm thankful everyday, for those dedicated enough to cover any and all ED shifts, so that I don't have to, on nights weekends or holidays. It wasn't long ago, prior to the EM speciality, that all of you non-emergency physicians would have had to.
