Medicine is easy... until something blows up into your face. (Sometimes literally I suppose.)
My first MS III rotation, IM. Everything was pretty cut and dry. Simple cases were simple cases. The MI's looked like MI's, the cancers behaved like cancers are supposed to look like, and I was wondering why everyone was saying this medicine thing was so difficult. Sure I understood the need for medical school, and perhaps an internship, but residency? fellowship? Then a patient came in with a classic presentation of "stomach flu." I gave the normal spiel, and was ready for the resident to send them out the door. However, he said something didn't seem right and did a neuro exam. An hour later the patient was in the ICU, the next day being operated on for a cerebral aneurysm. Lets just say that after that, those cases didn't seem so simple anymore.
If you are a licensed physician, you are going to see enough cases in training to realize that a 1% chance of something still means it can happen. Even when it can't happen it can happen. I have had a patient claim their GB was removed, the records said it was removed (second hand), they had appropriate scars, and upon imaging they still had their GB. Figure that one out. And remember that one when the EM physician calls you about an appy on a patient who the records say had it already removed.
My concern is that the "mid-level" training does not provide the volume of cases to "learn fear" before they hit the streets. Until you see a patient with your own two eyes have appy-symptoms end up with an MI you really don't believe it can happen. It makes sense that if you are in an academic setting, you are going to see more of the crazy cases and begin to learn fear. It also makes sense that after a decade or two of practice, PA/NP will pick up that fear. But I do worry that the ones straight out of training who are practicing independently haven't learned that yet. And that it is based on direct experience.
