The Impact of Establishing a Full Scope of Practice for Nurse Practitioners in Michigan

Core Content

This report analyzes the potential impact of defining a full scope of practice (SOP) for nurse practitioners (NPs) in Michigan. It reviews existing literature on how state-level SOP regulations for NPs affect various health care delivery outcomes, including provider supply, access to care, utilization of care, costs of care, and quality of care. The study is commissioned by the Michigan Council of Nurse Practitioners to inform policymakers and stakeholders about the possible effects of allowing NPs full autonomy and prescription authority.

Key Findings

• Provider Supply: Full SOP may lead to a possible improvement in provider supply. A plurality of studies found a positive association between full NP SOP and increased provider counts, though the causal relationship remains inconclusive due to the use of cross-sectional analyses in most studies.

• Access to Care: Full SOP could improve access to care. One strong study using national data found that residents in states with full NP SOP had better access to care. However, the evidence is limited to a single study, making the conclusion tentative.

• Utilization of Care: Full SOP may lead to a possible improvement in care utilization. All three reviewed studies found some relationship between NP SOP and utilization, though the direction and magnitude of the effect are not well established.

• Costs of Care: Full SOP might result in a possible reduction in costs. Studies suggest that allowing NPs full authority could lead to more efficient care delivery, but the evidence is limited and not definitive.

• Quality of Care (Patient-Centeredness): Full SOP could improve quality of care. Several studies found that NPs in states with full SOP provided care that was more patient-centered, though the overall effect remains inconclusive.

• Health Outcomes: Full SOP may have a possible positive effect on health outcomes. Some studies suggest that NPs with full SOP contribute to better health outcomes, but the evidence is not strong enough to draw a definitive conclusion.

Main Arguments

• Autonomy and Prescription Authority: Full SOP is defined as allowing NPs to practice autonomously and prescribe medications. Currently, NPs in Michigan function under the SOP of registered nurses (RNs), which limits their ability to practice independently and prescribe.

• Impact on Productive Capacity: SOP regulations can affect the productive capacity of NPs, which refers to the number, types, and appropriateness of services they can deliver. Restrictions may reduce the efficiency and volume of services provided.

• Physician Oversight and Costs: SOP regulations may influence physician oversight of NP practice, which in turn affects the types and appropriateness of care NPs can provide. Additionally, restrictive regulations may increase both monetary and "psychic" costs for NPs, potentially reducing their supply and practice hours.

• Variation in SOP Regulation: There is variation in how states define and implement SOP regulations. Some states use binary classifications (full vs. limited SOP), while others use more nuanced approaches. The studies reviewed used different methodologies, leading to varied conclusions.

Limitations and Considerations

• Limited Evidence: The evidence base is relatively small, with only a few high-quality studies available. This limits the ability to draw strong, conclusive conclusions about the effects of full SOP on all health care outcomes.

• Practice Context: The impact of SOP regulations on outcomes depends on the practice context, such as the availability of health information technology, the number of other healthcare providers, and the relationships between NPs and physicians.

• Need for Further Research: More research is needed to fully understand the effects of full SOP on access, utilization, costs, and health outcomes, particularly in Michigan-specific settings.

Conclusion

The report concludes that while there is evidence suggesting that full SOP could improve provider supply, access to care, utilization of care, and quality of care, the findings are not definitive. The impact of full SOP in Michigan is likely to be influenced by the broader practice environment and the specific implementation of the regulations. The findings are intended to guide policymakers in making informed decisions about the potential benefits and challenges of defining a full SOP for NPs in Michigan.
