RALEIGH — While the health care debate has usually focused on questions of insurance coverage and finance, the composition and delivery of medical services have been changing significantly. Some of these changes are worrisome. Others are promising.
A good example of the promising kind of change, to my way of thinking, is the emergence of physician assistants and nurse practitioners as frontline providers of primary care. While not receiving the breadth and depth of training that physicians receive, PAs and NPs can deliver many basic services at least as well as doctors at a fraction of the cost.
Consider these findings from a recent study by Julie Spero and Evan Galloway of the Cecil G. Sheps Center for Health Services Research at the University of North Carolina at Chapel Hill. They looked at counts of physicians, PAs, and NPs in our state and how they have changed since 2000.
All three groups of medical professionals have expanded — faster, even, than the state’s overall population. In 2017, there were 24,432 physicians, 6,027 physician assistants and 6,644 nurse practitioners. In other words, the combined number of PAs and NPs was about half that of doctors. In 2000, their combined total was only 22% that of doctors.
The disproportionate growth of physician assistants and nurse practitioners was especially pronounced in rural areas. The ratio of doctors to population in those counties has gone up only modestly so far this century. But the ratio of PAs to rural residents has more than doubled. The ratio of NPs to rural residents has nearly tripled.
When it comes to primary care, doctors continue to play a key role, of course. Still, most physicians practice in fields other than primary care. Most nurse practitioners, however, are mainly in the business of providing primary care. When it comes to preserving and extending such medical services in rural North Carolina, NPs have become indispensable.
To the extent government stands in the way, policymakers should take action. A series of good first steps can be found in a bill filed by a bipartisan group of state legislators earlier this year. Known as the SAVE Act, it would have updated state regulations on advanced-practice registered nurses.
Reforming the delivery of health care is always going to be about striking a balance. Some medical practices will continue to employ a range of professionals under the supervision of physicians. Others will deploy PAs, NPs and other providers in a variety of innovative ways, such as small practices within drug stores and other retailers, mobile clinics, telehealth enterprises and home visitation services.
State regulators should focus their attention on ensuring that providers are fully transparent about their training and capabilities so patients can make informed decisions. Regulators should not attempt to devise and enforce central plans about how all of this is going to work. They’ll get it wrong more often than not. And their decisions will be unduly influenced by special-interest groups, regardless of their good intentions.
The face of health care in North Carolina is changing — for the better, in this case.
