Not the PA students. The DO, OD, DPT, and DMD share a variety of 1st and 2nd year courses. The only course that the PA and DO students shared was the bogus "interprofessional education" (aka, "how not to be an A-hole like previous generation of physicians were") courses.
To be honest, I don't think so. There's a utility in having a little bit of knowledge about everything in addition to what's specifically in your specialty. You might not be able to treat everything, but to at least be able to go, "Oh, this patient has disease _____, characterized by _____, I might need to look something up just to be sure that it's not going to interfere with what I want to do."
For example, when I was on pain management we schedule a lot of epidural steroid injections for patients with back pain. The injections are done by an anesthesiologist under fluoroscopy (x-ray guided), but an NP runs the clinic and does the referrals. We had a patient who had osteogenesis imperfecta ("brittle bone disease." It's a collagen defect that drastically reduces bone strength to the point where it can be confused with child abuse). Now in my mind, "steroids + OI = Um... maybe a problem because glucocorticoids can futz with bone formation... this might be a problem."
The NP thought, "Steroids + OI = "What's OI? Oh, well, this is a local injection so it shouldn't be a problem."
I have no problem with the "local = not a problem." I have a problem with "What's OI?" especially when any 3rd year medical student knows what OI is.
