I think his point was that all physicians have a limited scope. Scope is limited by training. Ortho would never attempt to fix a AAA or do a fem-pop bypass and an FP doc would never attempt a TTFN. It all comes down to hospital privileging really.
While this is definitely true, it skirts a point that I personally think is ignored many times in these 'who is a physician/who should do what' discussions ...
While it's true that a FP doc wouldn't attempt bypass surgery nor would a CT surgeon treat grandma's cold, technically with an unrestricted license, unlimited funds for malpractice, and some access to a lax private surgical center/office ... they could. It "wouldn't happen," but that doesn't mean that there is some overriding restriction inherent within the "physician and surgeon" license that makes it impossible (as far as I know). Moonlighting during residency, various fields working in emergency rooms in small towns, and urgent care centers that take pretty much anyone with a DO/MD are a good example of this.
However ... the same can't be said for a DPM license. Even more realistically too, if that Ortho surgeon wants to fix a broken arm, a broken rib, replace a hip, and put some screws in the tib/fib ... he/she can. Again, the same can't be said for a DPM F/A surgeon.
I guess the point I'm trying to get at here is tres fold ...
1. Despite the fact that residency and common sense prevents DO/MDs from running wild and playing cowboy with scalpels, there are more restrictions inherent in the DPM license compared to the DO/MD license and they arise from a more complex situation than limitations based upon post-graduate training.
2. Another large difference that transcends practicing within one's specialization involves the difference between a 4th year medical student entering residency and a 4th year pod student entering residency ... if a medical student wants, he/she can become a dermatologist, a FM doc, a surgeon, an OB/GYN, an Orthopod, etc, etc, etc. A DPM student, on the other hand, knows exactly what they will be entering and is restricted (though not in a bad way as it's what they signed up for) to F/A surgery.
I've heard the argument many times that DPMs are simply physicians who specialize from the beginning of school (which many individuals think is more focused and advantageous to practice), but I think it's odd now that people are looking for some sort of bigger blanket ideal where DPMs should specialize from the beginning but also have privileges and a lack of restrictions comparable to those docs who don't specialize from the beginning, cover a larger/more vague educational experience and then enter a variety of different fields (basing this mainly off the discussed press release).
Which is it ... is it better to specialize from the beginning, enter a residency program which requires you to undergo the pre-doctoral specialized training, and limit yourself to said area? Or is it better to enter a more generalized medical model, pick a field, and really 'specialize' then? In my book, it's one or the other, but not some confusing combination of both (which is frankly something I see in the press release originally discussed in this thread).
3. As far as I know ... Podiatry is not an ACGME or AOA accredited residency program in the same vein as derm, FM, surgery, etc, etc. Because of this, I think it's kind off odd to state that the only difference between a Pod and an orthopod (for example) is that they chose different specializations. I think the difference between a dermatologist and an orthopod is that they chose different specializations, but when DPMs don't even have the option of becoming something else and DO/MDs don't have the option of becoming Pods, I simply think there are deeper differences than those usually discussed in these threads.
Having said all this ... I wanted to state that I think DPMs are great at what they do and I'll refer 10 times out of 10 to DPMs for any sort of F/A problems, no doubt in my mind. However, I do think this current issue with 'parity' is confusing and to me it seems like it boils down to DPMs wanting more recognition and reimbursement for performing the same procedures as Orthopods, which I see as completely fair, BUT I wish they would just come out and say that.
Frankly, the involvement of the LCME and support of Ortho groups makes me suspicious as to what they want to do with Podiatry as a field in CA, but this has been discussed before and I don't want to get into it again.
