As millions of Americans gain coverage for medical care in the coming years and as the need for primary care in patient-centered medical home (PCMH) models increases, our medical homes will need to provide more access to care. One such method is through advanced physician extenders which include physician assistants and nurse practitioners. Many entities are talking about allowing Advanced Registered Nurse Practitioners (ARNPs) work more independently without physician involvement. However, the vast difference in clinical training between family physicians and ARNPs is significant. Also, an effective provider in a PCMH is expected to manage without consultation a broad spectrum of disease. Therefore, practices without physician counterparts could lead to a tier of primary care that is limited in its effectiveness. ARNPs are a tremendous asset in providing some primary care services, ideally partnered with physicians in group settings, but have significant limitations when independently evaluating and managing undifferentiated patients due to the superficial coverage of medical topics during their training. The skill sets are complementary to each other, but not equal.
ARNP schools exhibit a wide variation of training standards from school to school and from state to state. There is no national accreditation body like the Accreditation Counsel for Graduate Medical Education (ACGME) that monitors advanced nursing profession schools or creates national standards for clinical experiences. Without a similar structure to the ACGME, it is impossible to assess the quality of the education across these various schools.
The diagnostic challenges primary care physicians face on a daily basis require they have extensive clinical exposure in order to perform efficiently. The depth of knowledge required to filter undifferentiated patients’ complaints and to understand the subtleties of management is vast. The average family medicine physician has 21,000 total hours of training, most of it with clear patient management responsibilities and decreasing levels of supervision. The total hours of training a nurse practitioner receives is 2,300 to 5,300 hours depending on the advanced nursing program, and much of the clinical training is observational. Many states only require a 30-day observation period of a licensed active physician before an ARNP can deliver care unsupervised. Grandfathering people into independent practice would be like grandfathering a family physician into a subspecialty after doing a month of observation in that specialty.
In the end, to practice independently, one should be judged by those who have the experience and background to make that assessment. Family physicians are the experts of primary care in this country and our understanding of what it takes to practice competently and independently is quite thorough. Family physician faculty that teach residents are skilled at making such assessments.
We believe there are excellent roles for physician extenders who work in collaborative settings with physicians, enabling more independence for the physician extenders. The medical team in the PCMH has key roles for Physician Assistants and ARNPs within its structure. Just as physicians gain greater skill with experience, these practitioners will gain great skill in many aspects of primary care as their experience develops over time. However, the underlying knowledge base and formative clinical experience cannot be shortcut. Not knowing what one doesn’t know can be dangerous to the public. On the physician side, we would never allow a 2nd- or 3rd-year medical student (who would have the equivalent amount of training as an ARNP), to evaluate and manage patients independently. Though states may pass laws that allow other providers with less training to practice independently, it doesn’t change the reality that without competent physician supervision, we are lowering the standard of acceptable primary care and creating a 2-tiered system of access for our community.
