Nurse Practitioners (NPs) are already part of the United States healthcare system, and the demand for primary care physicians is also extra. Due to physician shortages and the demand for increased access to medical care, several states have given Full Practice Authority (FPA) to NPs just to take patient history and examination, disease condition diagnosis, ordering and interpretation of diagnostic studies, and prescribing therapy including drugs without a referral from a physician.

American Association of Nurse Practitioners (AANP) describes Full Practice Authority as independent NP practice in education and training capability. In 2024, 27 states, the District of Columbia, and two United States territories had FPA legislation in place, and NPs practice independently. This paper provides a summary of state-to-state Full Practice Authority and its impact on delivering health care, workforce distribution, and patient outcomes in consideration.

State-by-State Guide to Full Practice Authority for NPs

1. Alaska

Alaska was an NP autonomy pioneer on day one by being the first state to practice Full Practice Authority years and years ago in 1984. NPs are the only providers who treat rural villages because Alaska has such a large rural landscape and lacks primary care physicians. The NPs would be able to practice, diagnose, examine, treat, and prescribe on their own as per the state policy, which attempted to reach the Indian villages and rural community. The NPs’ clinics in Alaska provided an excellent chance of evading hospitalization and chronic disease.

2. Arizona

Full practice authority was introduced to the state of Arizona in 2001, the state and nation’s first to share the independence that NPs have to offer. Causes of augmented demand for primary care services, i.e., rural Colorado and low-income populations. Arizona FPA bill encouraged growth of NPs clinics with greater access to chronic diseases medical care and prevention health care. Arizona State Board of Nursing provides continuous practicing NPs education and manpower planning for assured quality care.

3. Colorado

Colorado began to adopt FPA in 2010, and the NPs were allowed to practice independently after completing a 1,000-hour mentorship with an NP or physician practitioner. Colorado also witnessed other primary care clinics run by NPs open under the law, reducing patient waiting times and access to rural care. Evidence has always been that patients treated for primary care by NPs in Colorado under the supervision of physicians are no worse than patients treated by physician-supervised HOs in health outcomes, making FPA’s achievement to be justified.

4. Connecticut

Connecticut granted Full Practice Authority to NPs in 2014 following 3 years (or 2,000 hours) of direct physician supervision. Wider policy gain from increased delivery of primary care, especially to medically underserved areas. Health Affairs study believes that Connecticut FPA allowed enhanced NPs’ retention in practice as more NPs remained in practice within the state and did not move to another state for better policy.

5. Hawaii

Use of the FPA in Hawaii in 2008 has extended to island rural areas, where they never find themselves short of exposure to physicians. The law supports the government’s practice of NPs’ primary care services, particularly in a scenario where there is no balanced ratio of physicians. The clinics in Hawaii under NP practitioners have succeeded in extending their preventive services to care, particularly for diseases such as diabetes and hypertension.

6. Idaho

Idaho boasted the most favorable policy climate to NPs and achieved Full Practice Authority in 1971. The state has seen a growing rural health provider capacity since then, with NPs plugging holes in family practice, urgent care, and mental health. Idaho’s FPA policy has been shown to have higher patient satisfaction rates, especially in primary care.

7. Iowa

Iowa initially legalized the independent practice of NPA back in 1994. More NP presence followed in job function within the state, particularly within primary and mental care. Termination of supervisory arrangements provided a means by which NPs could establish independent practice, bringing more extensive patient access by under-served population. 

8. Maine

Maine has been a Full Practice Authority state since 2008 and is also one of the earliest states. The bill is credited to Maine’s remarkable number of NPs, and NPs specialize mainly in gerontology and family practice. NP-led chronic care programs in Maine have been significantly helped by a Maine aging population by avoiding hospitalization.

9. Maryland

Maryland granted complete autonomy to NPs in 2015, which served to reverse physician shortage and enhance access to care. Maryland’s law on full practice authority raised NP recruitment levels, particularly among high-risk populations and community health centers. Maryland NPs provide quality care at a lower rate compared to physician-practice settings, Maryland Nurses Association finds.

10. Minnesota

Minnesota decriminalized Full Practice Authority in 2015, enhancing the state’s core primary core primary care workforce. Research indicated that Minnesota’s care by NPs enhanced patient satisfaction and reduced emergency room use, showing the value of FPA in facilitating preventive care.

11. Montana

Montana has been a strong advocate of independent NP practice since 1994. Montana is a rural state as well as a rural populous state, and clinics of NPs are the most frequent first access to health among the rural populace. FPA in Montana has made remarkable effects with improved maternal health and further enhanced chronic illness management.

12. Nebraska

Nebraska possessed Full Practice Authority in 2015 due to NP and physician organization support. NPs practice independently and the number of NPs running clinics increased, and access in underserved and rural areas improved. 

13. Nevada

Nevada implemented FPA in 2013 to address critical shortages of physicians in rural counties. Primary care clinics staffed with NPs decreased waiting times for patients and improved preventive care services, particularly for the elderly and patients with chronic disease.

14. New Mexico

New Mexico gained Full Practice Authority in 1994, being an early leader in promoting NP autonomy. Practice experience has demonstrated that New Mexico’s rural patients are better served by the clinics of NPs, and that is proof of FPA’s ability to eliminate healthcare disparities.

15. North Dakota

North Dakota’s FPA of 2011 has diversified its rural healthcare workforce with NPs serving as PCPs in the majority of its rural communities. This has enhanced the provision of healthcare and hospitalization reduction in the state.

16. Oregon

Oregon has a large NP workforce that has had a Full Practice Authority since 1979. Oregon law allows NPs to practice independently and separately, leading to improved provision of primary care as well as improved patient satisfaction.

17. South Dakota

South Dakota has, since 2017, provided Full Practice Authority to NPs, a move that has improved healthcare access in rural regions. State healthcare leaders have confirmed that NPs fill huge gaps in primary and urgent care.

18. Vermont

Vermont has provided NPs with Full Practice Authority since 2011. The legislation has significantly improved NP recruitment and retention, thus improving healthcare access in urban and rural settings.

19. Washington

Washington State acquired FPA in 2005, and this is why Washington has the nation’s highest rate of NP care. Research found NP-delivered care in Washington is no more costly than doctor-delivered care and is equivalent quality for equivalent quality.

20. Wyoming

Wyoming small towns are uniquely empowered by its 2015 law that validated FPA, which allows NPs to practice independently in Wyoming’s small towns that lack enough physicians.

Conclusion

Full Practice Authority legislation bills have totally reshaped access to healthcare in all of America, particularly in low-income and rural states. The ability of NPs to fill healthcare gaps, reduce healthcare expenditures, and achieve better outcomes will continue to expand as more states become members of the NP-independence club.
