Fundamentally, I think that problem lies in the fact that no one believes in "Interventional Spine" as a bona-fide sub-specialty besides physiatrists, members of ISIS, and a handful of surgeons who want to employ them!
Most of drusso's post cut to save space...
1. Regarding Interventional Spine vs Pain Medicine: The term "Interventional Spine" implies that IS specialists have some special skill or knowledge about the spine. Those of us familiar with pioneer Interventional/Spine/MSK Physiatrists such as Slipman, Windsor, Dreyfuss, the Saul brothers, Joel Press, Stan Herring, Michael Geraci and second generation Heidi Prather, etc. likely support this view. Unfortunately, when I speak of "those familiar", it usually means Physiatrists, of which there are few. How are patients and the rest of the medical community to know if Dr. X, "Interventional Physiatrist/Spine Specialist" possesses the skills of those mentioned above, or if Dr. X did 28-30 months of inpatient work in residency followed by some weekend injection courses?
When it comes down to it, I think that the academy is responding to what most Interventional Physiatrists have in their hearts, to treat Orthopaedic patients and to supplement with interventional procedures. Whatever the reason why, I don't think it's completely financially driven as the salary a Physiatrist may earn from a surgical groups is likely to be lower than the income he could attain from a fully interventional pain practice.
To provide some historical backround for those who are med-students or those in training who may not know the whole story: During the 1980's-early 1990's, when it came to physicians who would treat spinal pain, there were surgeons, anesthesiologists (in the hospital), and opiate clinics. Stim was in its infancy, ESIs, SIJ and facet injections were done blind, disc procedures were not in wide use, etc. Physiatrists specializing in MSK/Spine were very rare, and Physiatrists and those from other specialties generally were not considered for pain fellowships. In 1993 ISIS and PASSOR formed, with many of the first Interventional Physiatrists taking great interest in both organizations. Physiatrists began to work for spine surgeons and assimilated some of their knowledge. ISIS is not a "pain medicine" organization, but is focused on the science behind the biomechanics of the spine and spinal injections. Academic pain departments and most "pain" practicioners lagged in this knowledge base, and thus, for a time, Interventional Physiatrists or Interventional Spine Specialists may very well have had what was considered special knowledge/skills/evaluative abilities pertaining to the spine. 2000-07, everyone is doing fluoro-guided everything, many private practice pain guys have refined their physical exam skills, academic pain departments are now assimilating Physiatric knowledge as well as that from Neurology, PASSOR has outgrown its special interest group frame and many of the most Interventional of Physiatrists have abandoned the AAPMR and definitely the AAP in favor of ISIS, NASS and ASIPP (organizations that support their practice models). So, today, the ball is back in the court of the Interventional/Spine/MSK Physiatrists. As with any other professions, those providing a service need to be able to justify their existence, or become extinct. Similary, the hybrid of OR Anesthesia/Part Time Pain Doc is the parallel to the Interventional Spine specialist who treats acute/subacute spine only and performs limited interventions. Can Physiatrists take it up another level and again demonstrate special knowledge/skills on a consistent basis? It's up to the ABPMR. So, is Interventional Spine/Physiatry just a watered down/limited version of Pain Medicine, or can IS/Spine Surgery be the equivalent of Primary Care Sports Med/Ortho Sports? I would say that it can, but it's up to us to demonstrate, with some consistency, the knowledge base and skill set that would justify IS as a bonafide sub-specialty.
Slipman's new book
Interventional Spine has a chapter or forward on the future of Interventional Physiatry. I'm looking forward to reading what he has to say on the matter.
2. Regarding the ability of the Pain Medicine specialist to diagnose and treat painful conditions of any etiology with all non-surgical treatments/modalities: Ideally, this would be possible. But, how many Physiatrists do any of us know who have this skill set? None? 1…2…maybe? Short of a Pain Medicine residency, a 12 month fellowship program will not be sufficient. The 12 month pain fellowships with PM&R, Neuro and Psyche rotations isn't going to cut it. Just as an example, one particular university pain fellowship is now having their fellows rotate with a Physiatrist I know personally who is not fellowship trained, knows little if anything about MSK or the Spine and has not done an EMG in the past 2 years (sounds like 3 months of time that could be spent reading films with a Neuroradiologist or in an Occ Med clinic evaluating patients).
There is a relative shortage of pain doctors in this country. Is it realistic to think we can fill that void with pain docs with a standardized skill set similar to the most highly interventional (all types of interventions)/spine/MSK trained "pain" Physiatrist? Or is this just a speed bump on the way to a pain medicine residency or the demise (a few more years of reimbursement cuts) of interventional pain management?
3. Regarding the progression of residency training and skill acquisition: It is clear that some academic PM&R departments have the necessary faculty/affiliations in place while others do not. Short or putting an MSK guy/gal in every chair position, there are going to be more than a few programs that struggle to make the necessary changes. If we are innovative, we will find ways around the problem. For those programs on the right track, Great! continue to evolve. For those programs that can't make the changes and survive, fine. We can still help those residents. Set up an ABPMR certification that can be met through residency or 6-12 months of approved ABPMR fellowship. Obviously, residents who are stuck in another 6-12 months are not going to be happy, but the bigger issue of establishing our expertise and protecting the specialty will be resolved.
