Description

Nurse practitioners (NPs) have graduate-level nursing education and must complete national board certification exams. NP scope of practice is regulated by state-level Nurse Practice Acts and Boards of Nursing and varies by state, ranging from requirements to collaborate with or be supervised by physicians to autonomy to provide care to the full scope of NP training and skills without physician oversight (e.g., independent practice and prescription authority). NPs frequently specialize in primary care, acute care, or mental health care (Xue 2016).

Expected Beneficial Outcomes

Improved quality of care
Increased patient satisfaction
Increased access to care

Evidence of Effectiveness

There is strong evidence that nurse practitioners (NPs) provide high quality routine care that is equivalent to (Stanik-Hutt 2013, Cochrane-Kuethe 2013, Newhouse 2011, Buerhaus 2015, AHRQ-O'Grady 2004, Cochrane-Laurant 2004, Horrocks 2002), and sometimes better than, comparable care provided by physicians (Martinez-Gonzalez 2014Stanik-Hutt 2013, Newhouse 2011, AHRQ-O'Grady 2004, Horrocks 2002). On average, nurse practitioners’ patient satisfaction scores are similar to (Stanik-Hutt 2013) or higher than physicians’ scores (Martinez-Gonzalez 2014Newhouse 2011, Cochrane-Laurant 2004, Horrocks 2002).

Overall, health status and outcomes for patients that receive routine care from NPs are equal to that of patients treated by physicians (Stanik-Hutt 2013, Oliver 2014, Cochrane-Kuethe 2013, AHRQ-O'Grady 2004, Cochrane-Laurant 2004, Horrocks 2002). NPs generally provide longer consults (Cochrane-Laurant 2004, Horrocks 2002), more health advice (Cochrane-Laurant 2004), and are more likely to take patient histories and discover history-related causes of health issues than physicians (AHRQ-O'Grady 2004).

Standardizing NP scope of practice laws to support full NP autonomy, within the scope of NP training, may increase the availability of primary care providers (Xue 2016, Buerhaus 2015, Barnes 2016, Spetz 2016, Naylor 2010, IOM-Nursing 2010, Graves 2016b). NPs with expanded scope of practice have been shown to improve provider availability for injured workers using worker’s compensation benefits, particularly in rural areas (Sears 2008).

States that do not require physician oversight appear to have more NPs than states that require greater oversight (Reagan 2013, Perry 2012). One study indicates higher numbers of primary care NPs in states with less oversight, particularly if NPs are paid the physician Medicaid reimbursement rate (Barnes 2016). Primary care NPs (Spetz 2016, DesRoches 2013) and family medicine NPs (Odell 2013) are more likely to practice in rural or health professional shortage areas (HPSAs) than NPs with other specialties or physicians. Primary care NPs also care for a greater portion of Medicare (DesRoches 2013) and Medicaid patients (Buerhaus 2015, Barnes 2016).

Models suggest that removing restrictions on NP scope of practice could reduce health care costs (Xue 2016). A study that compares states with full scope of practice regulations to states with more restrictions indicates that expanded NP scope of practice laws do not affect physician earnings (Pittman 2012).

Equalizing NP and physician reimbursement rates is a suggested strategy to encourage full NP autonomy, as allowed within state laws (Barnes 2016, IOM-Nursing 2010); as of 2012, Medicare reimbursed independent NPs at 85% of the physician rate (Cassidy 2013). 

Implementation

United States

As of March 2017, 22 states and Washington DC allow nurse practitioners to diagnose, treat, and prescribe medications without physician involvement (Campaign for Action). New Hampshire expanded the scope of practice of psychiatric mental health nurse practitioners (PMHNPs) in 2015, following extensive collaboration among PMHNPs, physician leaders, and policy makers focused on improving care within the state mental health system (de Nesnera 2016). 

National organizations such as Campaign for Action, the National Governors Association, and the Federal Trade Commission have efforts underway in support of expanded scope of practice for nurse practitioners (Campaign for Action, NGA-NP 2012, FTC-Gilman 2014). 

Wisconsin

As of 2017, Wisconsin requires collaborative agreements with physicians for nurse practitioners to practice and prescribe (AANP).
