I am surprised that this topic didn't get more discussion. This is essentially about the survival of osteopathic medicine as a profession.
To clarify, there is going to be MOC in the AOA Board certification. It is called OCC (Osteopathic Continued Certification). From that stand point, AOA BC offers no advantage in avoiding MOC.
What AOA is giving up is its "osteopathic identity" in the AOA Board Certification. What is the point of even having an entire osteopathic profession, when to AOA itself, OMM is now a mere optional "add-on". AOA has pretty much de-legitimize its own existence.
From another point of view.. with the ACGME merger, 95%+ of the DO will take the ABMS board. Why would you take AOA Board when you can take ABMS? There is no more DO Residencies! With no one to take AOA Board, the entire Board Certification System within AOA is going to be unsustainable financially. Furthermore, if there is not enough people to take these test, how can the Board write psychometrically valid tests?
I think the logic of AOA is this. If we have 2000 DOs taking Board Exam, we are likely pick up only the 5% of DOs who failed ABMS board who will take AOA board as a back up plan. 2000 x 5% = 100 people to take the test. AOA Board will not survive with only 100 people taking the test each year.
So AOA is probably thinking.. let us separate out the osteopathic component for the "elite DO" who want special osteopathic recognition. Then we will create another test with NO osteopathic components. This way both MDs and DOs who failed ABMS exam can take ours as a back up board. (see FAQ in the original post.. this is clearly stated by the AOA for MD to take the modified exam). we are now looking at 10000 MDs and DOs taking the ABMS test, 5% of failure is 10000 x 0.5 = 500. With 500 people or more taking the AOA test instead of 100, AOA board may just survive. Of course, AOA can't say their tests are "easier" The buzz word they will use will be the test is more "clinically relevant" or more "applicable to practicing physicians". They hope to pick up diplomats from bigger pool of people who failed ABMS.
I personally know DO graduating residents who signed up for both ABMS and AOA board exam after they come out of the newly minted, initially accredited, ex-DO, ACGME Program. After he find out he passed the ABMS, he simply skipped out taking the AOA board. Who can blame him? why would you need 2 board certification with 2 MOC/OCC requirement to sustain? With the ACGME merger, AOA is accelerating its own destruction.
I do not believe the AOA strategy will work. I think most people will simply try to retake ABMS next year then to settle for AOA board certification. The outcome of AOA decision remains to be seen.
I think it is possible for AOA to lose its total relevance or even cease to exist within 10 years time. I know this is a bold statement, but heck, just look at 10 years ago, I would never have imagined that I am now an ACGME residency program faculty. But here we are. We may all be MDs in 10 years time. AOA is taking away our reason to exist as a profession and made OMM simply an "add-on" to allopathic training.
