One of the negatives of the specialty is that we are viewed only as a commodity, as Arcan stated, that can be hired and fired easily at the whim of the CEO. I think residents and students should be aware of this prevalent negative in the community environment.
In the region I work, almost all EPs are independent contractors who are members of a group contracted to cover services for a hospital or system. Although, we are not employees of the hospital, the hospital controls the contract for the group. If the CEO does not like you for any reason, a bad outcome occurs, a political mistake occurs, or if the nursing administrators don't like you, you can be fired or pushed out in a heartbeat. The CEO just contacts the director of the group and states you either lose Dr. XYZ or we will pull your contract. The next day you notice Dr. XYZ is crossed off the schedule for all of his shifts and you never see or hear from him again.
I have seen this happen many times and generally to the older less efficient physicians or the physcians who fail to bend to the adminstration's "requests". With the abundance of new residency grads, positions in big cities are easily able to be filled. New grads are easier to be molded and indoctrinated into the desires of the CEO.
The CEO does not care what is the best practice of medicine or what benefits the patient the most. All he cares about is what the Press Gainey scores, Door-to-Doc times, patients per hour, and time-to-disposition metrics are. He doesn't care if you are good doc or not, only if you perform for the metrics.
As an EP you are not viewed as the other physicians in the hospital to the CEO. You make no money for the hospital in their eyes, bring in no prestige for the hospital, and only serve as a liability. The cardiologists, GI docs, neurosurgeons, etc, bring in money and prestige to the hospital. The ER just loses money. You are a metric, not a person, and one that can be easily fired and replaced.
With the probable future decrease in medicare reimbursement, hospital administrators will be further squeezed to milk out any profit they can. This only means more unreasonable "requests" of ED physicians and more unreasonable metrics to follow.
This is the future of EM.
