Dearth of cardiologists expected in next 10 years

The looming shortage of cardiologists is so severe that unless the training duration is shortened, the number of general cardiologists in practice in the year 2020 will be only two-thirds of the projected need, predicted at the annual meeting of the American College of Cardiology.

By 2038 — expected to be the peak year of the impending shortage — the number of general cardiologists on hand will be only 46.5% of the anticipated need for more than 62,400 of the physicians, leaving the nation nearly 34,000 short, added by a fellow in clinical electrophysiology at the University of Pittsburgh.

Shortening the duration of training required to be a general cardiologist — a key recommendation to address the coming workforce shortage proposed in the report of the 35th Bethesda Conference sponsored by the ACC —  will help, but not nearly enough.

The Bethesda Conference report recommended fast tracking of general cardiologists such that they would complete a 3-year cardiology fellowship after 2 years of general internal medicine residency instead of the conventional 3 years.

This would produce a greater number of general cardiologists with the same amount of funding.

But we calculated fast tracking would increase the number of general cardiologists practicing in 2020 from 22,365 to only 23,761 — still well below the projected need for 33,459, based on the accepted ratio of 6 per 100,000 population.

The Bethesda Conference didn’t address the possibility of fast-tracking fellowships in electrophysiology (EP) and interventional cardiology. This would entail 2 years of general cardiology fellowship followed by 2 years of subspecialty training.

We incorporated this concept into his modeling and concluded it would result in a further modest gain in the number of general cardiologists, because it would free up funds for close to 350 trainees who would no longer be taking a third year of general cardiology.

Doubling the number of cardiology fellows being trained and incorporating fast tracking for electrophysiology and interventional cardiology would essentially thwart the projected shortage of general cardiologists in 2020 but would produce a glut of general cardiologists by 2040.

The study shows we need to think more critically about the long-term implications of the workforce shortage.

If anything, projections as to future need for cardiologists are conservative, because they don’t fully incorporate the effects of rising rates of obesity, metabolic syndrome, and type 2 diabetes.

The notion of fast tracking electrophysiology training is tricky because the subspecialty is now reinventing itself. Electrophysiology “is really changing rapidly. It’s hard to sort out what it will look like in 10 years. Will it be a composite that includes components of heart failure? We predict that we’re likely to see multiple different tracks within EP.
