http://www.kevinmd.com/blog/ is not an unbiased reliable source IMO, and the study that was mentioned conflicted with another in the blog...one said inc one said dec. Blog. Blog. Blog.
While rotating on both the cardiothoracic surgery and cardiology rotations at my ~700 bed base, the cardiologists unanimously agree that they're getting more business and taking procedures from the surgeons--valve replacement, pacemakers, aneurysms etc. They do several pacemakers per day and get $$$. Don't know the reimbursement, but that practice's daily census, not including outpatient visits, is bigger than an IM census at a 200 bed hospital.
The surgeons unanimously agree that they are losing business to the cardiologists. They do trauma cabg M/T/A valve and tumor resection. Basically it. Which, due to length of procedure and longevity of treatment, is self limiting, according to the CT surgeons.
I definitely agree that reimbursement for reading scans is decreasing, but in this day and age, you shouldn't be limiting yourself to that as a cardiologist, and you definitely shouldn't be practicing on your own. According to cards.
Tell me this is illogical because I am basing my residency selection partly on cards, and it's good to hear other views.
