I discussed this earlier in a thread where certain proponents of the "IMG = inferior" route, especially for U.S. citizens, was hotly debated.
I would say again, as I did before, that a lot of this comes down to the fact that IMGs who want to practice in the U.S. have to pass the CSA, which is a direct test of PE ability as well as ability to interact with the patient.
The CSA test has been called everything from bigoted to unfair to demeaning. It has been likened to a country-club mentality - where certain "unsavory" candidates from an "unfavorable" population have to pony-up to greater membership requirements. This study has, at least in this regard, proven that basic clinical skills of IMGs -
possibly as a direct result of having to pass this additional licensure requirement - are at least equal to if not superior than USMGs.
It should be noted, too, that the "powers that be" that control U.S. licensure requirements are planning to soon implement the CSA test for ALL physicians seeking full licensure in the U.S. - that includes USMGs.
And, as far as the argument that a clinician should or would "check serum calcium levels the way everyone else does - a blood sample" precisely argues the point. The marvels of modern technology should not override simple, good, examination-based medical diagnosis. A good clinician SHOULD order ONLY the tests he/she thinks are needed, and not carpet-bomb the lab with a slew of unnecessary and costly blood examinations. Medicine is just as much a practice of understanding signs and symptoms as it ever has been. But, with the increased emphasis on molecular diagnosis, it's no wonder that U.S. schools are focusing less time (possibly) on training in physical examination when there's so much else to cover.
Nonetheless, just because a test exists shouldn't mean you have to order it. Of course, in today's heavy malpractice themed practice environment, it's no wonder that clinicians often reach for the Vacu-tainer in lieu of relying on good clinical examination skills. And, yet we wonder why the costs of U.S. healthcare are skyrocketing...
Still, missing rebound tenderness at McBurney's point is just plain inexcusable.
