I recently got the good news that I passed the board recertification exam for the American Board of Internal Medicine (ABIM). As a bit of background, ABIM is a national physician evaluation organization that certifies physicians practicing internal medicine and its subspecialties (every other specialty has its own board certification body like ABOG for OB/GYNs and ABS for surgeons). Doctors practicing in most clinical environments need to be board-certified to be credentialed and eligible to work. Board certification can be accomplished by taking a test every 10 years or by participating in a continuing education process known as LKA (Longitudinal Knowledge Assessment). I decided to take the big 10-year test rather than pursue the LKA approach. For my fellow ABIM-certified docs out there who are wondering why I did the 10-year vs. the LKA, I’m happy to have a side discussion, but it was largely a career timing issue.

Of note, board certification is different from the USMLE (United States Medical Licensing Examination) which is the first in a series of licensing hurdles that doctors face in medical school and residency, involving 3 separate tests (USMLE Step 1, 2 and 3). After completing the USMLE steps, acquiring a medical license is a separate state-mediated process (I’m active in NY and inactive in PA) and has its own set of requirements that one needs to meet in order to practice in any one state. If you want to be able to prescribe controlled substances (opioids, benzos, stimulants, etc.), you will need a separate license from the DEA (the Drug Enforcement Administration, which is a federal entity). Simply put, you need to complete a lot of training, score highly on many standardized tests, and acquire a bunch of certifications (that cost a lot of money, BTW) to be able to practice medicine in the USofA.

What I learned in preparing for the ABIM recertification exam:

1.) There’s SO MUCH TO KNOW to be a doctor!

To prepare for the exam I used the New England Journal of Medicine (NEJM) review course which included roughly 2,000 detailed case studies that covered all the subspecialty areas of internal medicine. If you figure that each case involves mastery of dozens of pieces of medical knowledge, the exam requires a physician to remember tens of thousands of distinct pieces of information just for one specialty (remember that the medical vocabulary alone consists of tens of thousands of words). In addition, the individual facts mean nothing without a mastery of the basic underlying concepts, models, and frameworks of biology, biochemistry, human anatomy, physiology, pathophysiology, public health, etc. etc. Then there’s all the stuff you need to know for your specific speciality: medications, diagnostic frameworks, treatment guidelines, etc. It’s a lot. There’s a reason it takes the better part of a decade to gain any competency as a physician. So whenever I hear a non-doc saying that they’ve been reading up on XYZ and “I think I know almost as much as my doctor!”, my answer is always “No you don’t. Not at all. Not even a little bit. Stop it.”

2.) There is so much that we DON’T KNOW as doctors!

What was particularly striking to me as I did my review was how often I encountered a case or a presentation where:

• It’s unclear what causes a disease,
• The natural history of the disease is unclear,
• We don’t know how to treat the disease,
• We know how to treat the disease but we don’t how the treatment works,
• We don’t know what treatment is most effective, or
• We don’t know what diagnostic test is best.
• And on, and on, and on…

It’s estimated that there are more than 50,000 (!!) active journals in the field of biomedical sciences publishing more than 3 million (!!!!) articles per year. Despite all this knowledge generation there’s still so much we don’t know about the human body and how it works. I think some people find doctors arrogant, but anyone who really knows doctors and physician culture can tell you that doctors possess a deep sense of humility that comes out of knowing that you actually know very little.

3.) Someday soon the computer doctor will FOR SURE be smarter than the human doctor.

The whole time I was preparing for the test, I kept telling myself that there was nothing I was doing that a sufficiently advanced computer couldn’t accomplish.
