Nurse practitioners helped fill a shortage in primary care, but they're increasingly headed to specialties

From CBS (link: https://www.cbsnews.com/news/nurse-practitioners-specialty-medicine-workforce-trend/):

For many patients, seeing a nurse practitioner has become a routine part of primary care, in which these "NPs" often perform the same tasks that patients have relied on doctors for.

But NPs in specialty care? That's not routine, at least not yet. Increasingly, though, nurse practitioners and physician assistants are joining cardiology, dermatology and other specialty practices, broadening their skills and increasing their income.

This development worries some people who track the health workforce, because current trends suggest primary care, which has counted on nurse practitioners to backstop physician shortages, soon might not be able to rely on them to the same extent.

"They're succumbing to the same challenges that we have with physicians," said Atul Grover, executive director of the Research and Action Institute at the Association of American Medical Colleges. The rates NPs can command in a specialty practice "are quite a bit higher" than practice salaries in primary care, he said.
