So then would you argue that any standardized testing is unnecessary? USMLE Boards? ABA boards? If all residencies are capable of "adequately" training residents, why is even specialty certification required? And is the goal of residency programs to graduate "adequate" physicians?
A few points to consider:
1) Why do you think the ACGME is better suited to create and administer these tests that the ABA?
2) The certification exam is just one piece of the subspecialty certification. To maintain the certification, you must take annual CME. Self-learning and continuous improvement is a cornerstone of Western medicine, if you believe in that. Take away certification exams, you might as well take away CME. I'd like you to consider how many physicians will actually continue to learn and stay up to date.
3) It's a bit of a stretch to consider all GME programs equal. It's also a stretch to consider each of these programs actually have resident education as their top priority. The minute you take away the board exam, you take away all resident education activities at most programs. Without an exam for which to prepare, there is no longer incentive for programs to teach residents, beyond the benevolence of teaching the future generation. Residents simply become incredibly cheap CRNAs. `
As mentioned, cost should not be a barrier. Any program demanding you pass should be paying for it. And if anyone on here really believes a one-time $1800 expense is too steep, let's reconsider how well we are paid. That's $35 per week. A fancy coffee per day. I exceed that benefit in the free lunch I get, every single day in the doctor's lounge.
So it comes down to why we should be expected to take the exam. Well, it's material that should be expected knowledge for anyone claiming to be a "Cardiac Anesthesiologist". If you call yourself a Cardiac Anesthesiologist, prove it. That doesn't mean everyone doing hearts. I sometimes do Peds. I don't consider myself a Pediatric Anesthesiologist. If you don't want to jump through the hoops, then don't. Just because we don't like it doesn't mean it's wrong.
