If my fellow angiographers prove unwilling or unable to accept or secure for their patients the clinical responsibilities attendant on transluminal angioplasty, they will become high-priced plumbers facing forfeiture of territorial rights based solely on imaging equipment others can obtain and skill still others can learn.
—Charles Dotter
American College of Surgery meeting in 1968
The above statement was discussed by the founder of VIR specialty.
I have seen much of this at training programs and in private practices and my goal in training and beyond was to develop a sustainable practice in the various conditions I wanted to treat and I realized early on it required a solid understanding of the disease that I wanted to manage and not just technical proficiency.
The key is to go to a training program where you will learn how to compete for referrals. This also requires dedicated time to see patients in the office, admit them and follow them longitudinally. If you want to learn PAD , learn the basics of vascular disease Keep HBa1c<7, high intensity statins, antiplatelet trials (CAPRIE) ; Voyager and COMPASS. Go to primary care, podiatry, nephrology and endocrinology , wound care centers and offer them your skill set. Be willing to admit the patient and start them on iv antibiotics if they develop a foot infection.
Expecting specialty referrals to come into your lap is transient and not sustainable. Need to also be able to market directly to patents and follow patients longitudinally, much of what we do needs repeat interventions (PAD vessels restenose, aneurysm repairs develop endoleaks, fibroid symptoms recur post UAE (EMMY 10 year data) , and retrospective data from BPH shows recurrence (Pisco et al).
There are certainly surgical and medical specialties who can gather interventional skills and already offer these therapies and it will be up to you to go and compete with them for these referrals. The difference is they may have already developed a natural referral service and like a new company coming into a space you will have to change referral patterns. It is no different than a new car company coming in and competing with historically well recognized brands such as Ford, GM, Toyota, Honda, BMW and Mercedes. If you are interested in building a spine practice (you will have to compete with others who provide such care (ortho; neurosurgery; pain anesthesia; PmNR, neuro IR; MSK rads etc) . You will have to garner knowledge of the differential of back pain, conservative therapy for back pain, natural history of osteoporosis, imaging interpretation , interventional treatment and follow up of these patients.
