Pathways to Independent Primary Care Clinical Practice: How Tall Is the Shortest Giant?

Area of Science:

• Healthcare policy
• Medical education
• Primary care workforce

Background:

• Physicians, nurse practitioners (NPs), and physician assistants (PAs) provide primary care despite varied training.
• Licensing requirements, not educational bodies, dictate minimum training standards.

Purpose of the Study:

• To examine the minimum education and training required for primary care practice.
• To evaluate if current training disparities necessitate a reconsideration of medical education or scope of practice.

Main Methods:

• Analysis of existing state licensing requirements for physicians, NPs, and PAs.
• Review of initial studies on patient outcomes across the three professions.
• Proposal for future rigorous studies on practice patterns and outcomes.

Main Results:

• Current minimum training: NPs (6 years, 27.5 weeks supervised clinical experience [SCE]), PAs (6 years, 45 weeks SCE), Physicians (≥8 years, 110 weeks SCE).
• Initial studies suggest equivalent patient outcomes, but require rigorous follow-up.
• Unmatched medical graduates and PAs meet or exceed NP minimums.

Conclusions:

• Rigorous studies are urgently needed to confirm or refute outcome equivalence.
• Findings will inform optimal training, scope of practice, and workforce development for primary care practitioners.
• Recommendations include reconsidering physician education, raising NP/PA minimums, or defining scopes of practice based on training.
