Research presented at the American Enterprise Institute focused on shortages in primary care and the effect of nurse practitioners scope of practice restrictions. The study findings, presented by Dr. Peter Buerhaus, healthcare economist and professor of nursing at Montana State University, show projected growth in the NP workforce, with primary care nurse practitioners more likely than physicians to practice in rural areas. However, the research shows that access to PCNPs is significantly less in states with laws restricting NP's scope of practice. The research also shows that "beneficiaries who received their primary care from NPs consistently received significantly higher-quality care than physicians’ patients in several respects." Regarding the claim that scope of practice restrictions are necessary to protect the public from low-quality providers, "Analysis of different classifications of state-level scope-of -practice restrictions provided no evidence that Medicare beneficiaries living in states that imposed restrictions received better-quality care."
