At best it's an inefficient way to learn what you could learn more efficiently on Medicine, and at worst it's a never ending parade of gallbladder surgeries that add nothing of value to your education. Surgery (and OB) should be electives for students who plan have a career in the OR.
I don't know how your rotations were set up, but the things that I learned on surgery were in no way, shape, or form, things that I could have learned on medicine.
You don't learn to suture on medicine. You don't learn how to properly evaluate hernias on medicine. I saw ONE acute abdomen on medicine, as opposed to the half-dozen I saw on surgery. I never learned how to manage SBOs on medicine, either. I learned about breast cancer on OB and surgery - the medicine residents I saw barely knew how to properly do a breast exam. The list goes on and on.
As an FM resident, I use what I learned on my surgery rotationS (I had to do them as an FM resident, too) every week in clinic. Hernias, rectal bleeding, hemorrhoids, possible breast cancer, I&Ds, suturing up lacerations, wound care - all stuff I learned on surgery; these were topics that were never brought up on my medicine rotation.
Plus, at least you get to see on surgery what truly is and isn't an emergency. Medicine residents are terrible at figuring out what can be done as an outpatient and what can't, which leads to such moves such as consulting trauma surgery for a stat breast biopsy (which my resident made me call in
).
As for OB....if I have to hear one more IM trained person tell me that it's "probably HELLP" for every pregnant patient, even those who are only in their 2nd trimester....
(Hint: HELLP is seen before the 3rd trimester in case studies. It's very rare to see it that early in pregnancy.)
Finally, by your logic, it's a waste of time for people going into pathology to do ANY clinical rotations. After all, they're never going to do it again, so why make them? Why make future pediatricians do adult IM rotations, when everything they need to know about general medicine they could learn just as well on the peds floors? Why make future anesthesia residents do a psych rotation? etc.
