The series looks at professions discussed by the California Future Health Workforce Commission and its subcommittees and workgroups during spring and summer of 2018. Each brief begins by describing the profession, including its legally permissible scope of work, and educational requirements. The brief then outlines how California’s permissible scope of practice compares with that of other states and provides a summary of research studies on the impact of the profession’s scope of practice on access to care, care quality, and costs. Finally, it summarizes demographic characteristics, practice settings, and geographic distribution. Visit www.futurehealthworkforce.org to learn more. California Health Care Foundation Note: This report was updated in July 2019 to provide more detail about physician oversight requirements, particularly in states in which there is a transitional oversight period. 2 C alifornia is 1 of 22 states that restricts nurse practitioners (NPs) by requiring that they practice and prescribe with physician oversight, and it is the only western state with this requirement. A large body of research has linked such restrictions to lower supply of NPs, poorer access to care for state residents, lower use of primary care services, and greater rates of hospitalizations and emergency department visits. Although proponents of scope of practice restrictions argue that physician oversight is necessary to ensure quality of care, dozens of studies demonstrate both that the quality of NP care is comparable to that of physician care, and that there is no difference in the quality of care when there are no physician oversight requirements. Finally, several studies have found that full practice authority for NPs is associated with lower costs of care. This paper describes the regulations that govern the scope of practice for NPs in California and in other states, and summarizes recent research on how these laws impact care. Overview of the Profession Nurse practitioners (NPs) are registered nurses (RNs) who have completed additional education to prepare them to deliver a broad range of services including the diagnosis and treatment of acute and chronic illnesses.1 Nurse practitioners trace their history to the late 1950s, when RNs with clinical experience began to collaborate with physicians in the delivery of primary care, particularly in rural areas. Nurse practitioners are one of four categories of advanced practice registered nurses (APRNs): NPs, certified nurse-midwives (CNMs), nurse anesthetists, and clinical nurse specialists. NPs provide a broad array of health services, including taking health histories and performing physical exams, diagnosing and treating acute and chronic illnesses, providing immunizations, performing procedures, ordering and interpreting lab tests and x-rays, coordinating patient care across multiple providers, providing health A large body of research has linked restrictions on scope of practice to lower supply of NPs, poorer access to care for state residents, lower use of primary care services, and greater rates of hospitalizations and emergency department visits. How Scope of Practice Is Modified in California Scope of practice laws establish the legal framework that controls the delivery of medical services. The reach of these laws encompasses the full range of licensed health professionals — ranging from physicians and physical therapists to podiatrists and dental hygienists. Scope of practice laws govern which services each category of licensed health professional is allowed to provide and the settings in which they may do so. With few exceptions, scope of practice statutes are set by state governments. State legislatures consider and pass the statutes that govern health care practices. Regulatory agencies, such as medical and other health professions boards, implement the statutes through the writing and enforcement of rules and regulations. Such laws and regulations vary widely from state to state. Some states allow individual professions broad latitude in the services they may provide, while others employ strict limits. The nature of the limitations can either facilitate or hinder patients’ ability to see a particular type of provider, which in turn influences health care costs, access, and quality.

The Veterans Health Administration reports that the roles of NPs are similar to those of physicians in their system,2 and NPs are a key source of care in community health centers and nursemanaged health centers nationwide.3 For a detailed look at NP demographics and practice patterns in California, see Appendix A. Nurse Practitioner Education The first formal education program for nurse practitioners was established at the University of Colorado in 1965 with a focus on the delivery of primary care in rural communities.4 The program was codesigned by a physician and a nurse. This and other early NP education programs conferred certificates, and many of the initial graduates of these programs had received their RN education in hospital-based diploma programs. The California Board of Registered Nursing (BRN) began certifying NPs in 1985, and all states now certify or license NPs. Forty-five states and the District of Columbia require completion of a master’s, postgraduate, or doctorate degree from an accredited NP program, and then certification from a nationally recognized certifying body such as the American Academy of Nurse Practitioners or the American Nurses Credentialing Center.5 NP certification in California can be obtained by successful completion of an NP education program that meets BRN standards, or by certification through a national organization whose standards are equivalent to those of the BRN. There are 23 approved NP programs in California. Since January 2008, California requires that new NP applicants who have not been qualified or certified as an NP in California or any other state possess a master’s degree in nursing, a master’s degree in a clinical field related to nursing, or a graduate degree in nursing, and complete an NP program approved by the board. A nurse practitioner must have BRN certification to practice in California, but certification from a national professional association is not required. Nurse practitioners can be prepared and certified in many clinical areas, including family practice, pediatrics, women’s health, psychiatry, acute care, and community/ public health. NP education covers a common range of topics including physiology, various body systems, and diagnosis and treatment of illnesses and conditions. A California Health Care Foundation recent development in NP education is the establishment of the Doctor of Nursing Practice (DNP) degree, which is offered by an increasing number of nursing schools. However, the number of NPs educated in these programs is small thus far. Practice Oversight of Nurse Practitioners in California In California, NP practice is governed by the state nurse practice act.6 The Board of Registered Nursing has promulgated regulations that require the NP to work under standardized procedures for authorization to perform overlapping medical functions (CCR § 1485).7 This regulation requires that NPs work under collaboration with a physician and adhere to standardized procedures developed through collaboration among administrators and health professionals, including physicians and surgeons. California NPs must obtain additional certification from the BRN to “furnish” (prescribe or order) drugs or devices under standardized procedures developed with the supervising physician and surgeon.8 As collaborators, physicians take legal responsibility for the NP’s practice and are expected to determine the appropriate level of supervision, communicate regularly with the NP, and oversee the NP’s practice and quality of care. More than half of NPs in jobs with an NP title in California report that they are “always” (39.7%) or “almost always” (16.4%) involved in the development or revision of standardized procedures. Nearly 8% of NPs report never having a voice in the development of standardized procedures.9 There are no rules regarding proximity of the physician to the NP, and thus a physician can provide supervision remotely — even from hundreds of miles away. In 2017, 72.6% of California NPs reported that their collaborating physician practiced in the same location they did, while 9.8% of NPs indicated that their collaborating physician was at another practice or system.10 There are no data regarding the share of California physicians who formally collaborate with one or more NPs or the share who are willing to collaborate with NPs. One specific area of regulation concerns the prescribing of buprenorphine for the treatment of opioid use disorder in office settings. Since 2002, buprenorphine can be prescribed in office-based care settings by a provider 4 who has a waiver under the Drug Addiction Treatment Act (DATA) of 2000.11 This prescribing was limited to physicians until passage of the Comprehensive Addiction and Recovery Act (CARA) in 2016, which allows NPs and physician assistants (PAs) to obtain waivers.12,13 CARA stipulates that if a state requires physician oversight of NP/ PA prescribing, the physician must have a DATA waiver to prescribe buprenorphine or must meet other specific qualifications.14 These restrictions impact the percentage of NPs engaged in treatment for opioid use disorder.15 Overview of Regulations in Other States State regulations regarding NP scope of practice vary widely. In an effort to encourage greater consistency across states, the National Council of State Boards of Nursing has developed a Model Act, which provides consensus-based recommendations regarding how an ideal nurse practice act should be written.16 The Model Act explicitly defines the scope of practice of APRNs to include conducting assessments; ordering and interpreting diagnostic procedures; establishing diagnoses; prescribing, ordering, administering, dispensing, and furnishing therapeutic measures; delegating to assistive personnel; and consulting with other disciplines and providing referrals. The Model Act recommends that APRNs be licensed independent practitioners. In 14 states and the District of Columbia, NPs can practice and prescribe without physician collaboration or supervision immediately upon licensure, and in 14 additional states an NP can practice without physician oversight after a transitional period during which supervision by a physician or another NP is required. States that require physician collaboration or supervision of NPs have a variety of specific regulations related to this supervision, described below and summarized in Table 1 (see page 6).17,18 Formal agreements and chart review. Twenty-two states require that an NP be supervised or have a written collaboration agreement with a physician in order to practice and prescribe medications, regardless of how long the NP has been in practice. In some states, a physician must review a specific share of patient records, and other states specify that chart review must occur but do not specify what share. Physician proximity. Some states specify the maximum distance permitted between the NP and physician; some states specify the number of miles, such as Mississippi (75  miles), and some states require a certain proximity for a specified amount of time. For example, in Alabama, the physician must be on-site for at least 10% of the NP’s hours. Consultation frequency. Some states specify the frequency of consultation between an NP and physician, which can range from every 30 days (Tennessee) to annually (Ohio). Other states require an agreement regarding frequency of collaboration but do not specify that frequency. The frequency with which collaborative practice agreements must be reviewed is specified by some states. Supervision rules. In many states there are limits to the number of NPs a physician can supervise. Several states permit NPs to practice without supervision after a transitional period. These states can specify the number of supervised hours required, number of months required, or both. Some of these states allow the supervision to be provided by another NP.

California Health Care Foundation 6 Recent Changes in Other States Since 2010, 21 states have enacted regulatory changes that have provided NPs with a greater degree of practice authority, including 9 states that now allow NPs to practice without physician oversight. These changes are consistent with recommendations from leading authorities, including the National Academy of Medicine and the National Governors Association, which have stated that NPs be allowed to practice without physician oversight.19, 20 In addition, the US Federal Trade Commission (FTC) issued a policy paper in 2014, Competition and the Regulation of Advanced Practice Nurses, which advised policymakers that “APRN scope of practice limitations should be narrowly tailored to address well-founded health and safety concerns, and should not be more restrictive than patient protection requires.” The FTC policy paper also noted that the FTC has “consistently urged state legislators to avoid imposing restrictions on APRN scope of practice unless those restrictions are necessary to address well-founded patient safety concerns.”21 States have gradually granted NPs authority to practice autonomously. Between 2011 and 2019, NPs were granted full authority to practice and prescribe without physician oversight in nine states: North Dakota (2011), Vermont (2011), Nevada (2013), Rhode Island (2013), Connecticut (2014), Minnesota (2014), Maryland (2015), Nebraska (2015), South Dakota (2016), West Virginia (2017), and Virginia (2019). In addition, incremental changes were made to provide NPs with greater practice authority in Alabama, Delaware, Florida, Illinois, Kentucky, Michigan, New York, Ohio, Texas, Utah, and West Virginia.22 Nine of the states that have recently established full practice authority for NPs require a transitional period of oversight by a physician or NP; the exceptions are North Dakota and Rhode Island. Prescribing authority, one major element of NP scope of practice, has changed over the years. In 2006, Georgia became the last state to grant NPs prescriptive authority,23 and in 2016, Florida became the last state to authorize NPs to prescribe controlled substances.24 Today, NPs hold prescription privileges in all 50 states and the District of Columbia. NPs may prescribe controlled substances, including Schedule III substances in every state and Schedule II substances, such as oxycodone, methadone, and fentanyl, in all but 7 states.25 A similar trend toward expanded practice authority is visible at the federal level. In 2016, the US Department of Veterans Affairs announced new regulations permitting full practice authority for the nearly 6,000 APRNs in its workforce, allowing them “to practice to the full extent of their education, training, and certification, regardless of State restrictions that limit such full practice authority.”26 Examining the Evidence for Practice Expansion: A Summary of Research NPs and physicians both agree that it’s valuable for NPs to have some association with physicians.27 However, daily autonomy of NPs and their ability to fully use their skills is diminished when state regulations require physician oversight.28 In a 2017 survey, 60.2% of California NPs reported “always fully using their NP skills,” and an additional 21% were almost always doing so. California’s relatively restrictive scope of practice regulations may be a factor for the 19% of NPs who are not at least “almost always” fully using their skills.29 A large body of research has examined the relationship between scope of practice regulations for NPs and access to care, quality of care, and health care costs (see Tables 2, 3, and 4). Access to Care Physician supply will meet less than half of demand for primary care in 2030, but this gap can be filled by projected growth in nurse practitioner and physician assistant supply.30 Many policy leaders point to the elimination of unnecessary barriers to nurse practitioners’ practice as a means to address primary care shortfalls, particularly in rural and underserved areas.31,32 Rural and vulnerable populations. Numerous studies have found that state regulations requiring physician oversight of NPs and other restrictions on NP practice are associated with decreased access to care for patients, particularly in rural regions and for Medicaid enrollees. In 2016, a systematic review of the impact of state NP scope of practice regulations on health care delivery determined that “[s]tates granting NPs greater SOP authority tend to exhibit (a) an increase in the number and growth of NPs through higher APRN educational enrollment California’s Nurse Practitioners: How Scope of Practice Laws Impact Care 7 and migration and (b) greater provision of primary care by NPs and expanded health care utilization, especially among rural and vulnerable populations.”33 Removing barriers to mental health care. The large projected shortfall of psychiatrists in California can be lessened by the use of psychiatric/mental health NPs because both can prescribe medications.34,35 Two papers have reported that scope of practice regulations create barriers to the use of psychiatric/mental health NPs in public health systems in California, in part because public health directors find the regulations confusing and have difficulty finding psychiatrists who are willing to supervise NPs.36,37 See Table 2 for a compilation of recent research findings on access to care.

Quality of Care Some proponents of restrictive scope of practice regulations for NPs cite concerns about the quality of care that might be provided by NPs relative to physicians, since NP education is shorter and more narrowly focused on primary care and a subset of specialty fields. However, multiple systematic reviews of the literature conclude that NPs provide care of comparable quality as physicians, even when NPs practice without physician oversight.38 Findings were similar for studies that looked at primary care in general and for studies that looked at specific aspects of patient care, such as prescribing, chronic disease management, and ordering diagnostic tests. Researchers looking at long-term care settings and at rural and community health centers came up with similar findings. More tests? Two studies, published in 1999 and 2015, report that NPs order more tests and generate more specialty referrals than physicians. Both studies, however, have significant shortcomings including small sample size, possibly misattribution of who ordered tests, insignificant differences, and subanalyses with contradictory findings.39 – 41 As mentioned, other studies have found that NPs do not order more tests or produce more specialty referrals than physicians. Surveys of nurse practitioners. Nurse practitioners report that restrictive scope of practice laws negatively impact the quality of care they are able to provide. In the BRN survey of California NPs, 11.3% of those employed in NP positions say scope of practice restrictions are a major barrier to their ability to provide high-quality care, and 29.1% say scope of practice restrictions are a minor barrier. Similarly, an exploratory survey found that NPs perceived that requirements for physician oversight impacted their practice and may jeopardize patient safety.42 See Table 3 on page 10 for a detailed list of research findings on quality of care.

California’s Nurse Practitioners: How Scope of Practice Laws Impact Care 11 Productivity and Cost of Care Restrictive NP scope of practice regulations could affect the cost of care in two key ways. First, by limiting the supply of NPs and access to care, patients may be more likely to use expensive services including emergency departments. Second, employed physicians’ salaries and bonuses are often based on personal productivity, and the time required to supervise an NP reduces the number of patients the physician can see. Physicians thus often expect payment to compensate for their supervisory work; market data find that practices offer physicians stipends for NP supervision ranging between $5,000 and $15,000 per year.43 This cost is passed to the payers of health care services. Cost-effective. Several research teams have examined the cost-effectiveness of NP practice, including in teambased care, and found that NP care is linked to better patient outcomes in ambulatory care, and is potentially cost saving. Lower cost of care. Other researchers focused specifically on whether health care costs are lower when NPs do not have to be overseen by physicians, and found that eliminating physician oversight is associated with lower costs for ambulatory care and well-child visits, as well as in retail clinics. Removal of scope of practice restrictions also decreases the number of malpractice payments made by physicians by as much as 31%. See Table 4 for a detailed list of research findings on productivity and cost of care. Table 4.

California Health Care Foundation 12 Appendix A. The Landscape of Nurse Practitioners In 2017, 20,337 certified NPs lived in California; the number increased 39% from 2010, when there were 14,636 certified NPs,44,45 compared to approximately 120,000 in 2007 to more than 234,000 in 2017 nationally.46 The distribution of NPs varies across California (Figure A1). Higher NP-to-population ratios are generally found in the San Francisco Bay Area, northern coast (Humboldt and Mendocino Counties), and Sierra region east of Sacramento. Lower ratios are observed in the northern Sacramento Valley and northern San Joaquin Valley. NPs can specialize in one or more fields; most focus on primary care–related fields such as family care, adult gerontological care, or pediatric care (Table A1). Psychiatric/mental health care is the focus of 7.8% of those who have NP certification and 5.5% of dual NP-CNMs, indicating that about 1,573 NPs have education in this field. Figure A1.

California’s Nurse Practitioners: How Scope of Practice Laws Impact Care 13 Demographic Characteristics The California BRN commissioned a survey of NPs and certified nurse-midwives (CNMs) in 2017.47 At the time the survey was conducted, 20,337 certified NPs were living in California, 569 of whom were dually certified as an NP and a CNM. Some of the information provided in the survey report separates those with NP-only certification from those with dual certification. The majority (53.4%) of NPs is over 45, and almost twothirds of dual-certified NP-CNMs are over 45. The largest age group for NPs in 2017 was 35 to 44 years, accounting for 32.3% of the population (Figure A2). NPs are predominantly female, with only 10.1% of NPs and 1.5% of NP-CNMs being male in 2017. As seen in Figure A3, more than 60% of NPs are non-Hispanic white, while more than 80% of NP-CNMs are non-Hispanic white. The largest non-white ethnicities for NPs are Hispanic, (8.4%), Filipino (8.3%), and other Asian/Pacific Islander (10.9%). Figure A2.

Employment rates of NPs vary somewhat between urban and rural areas. NPs with only NP certification have higher employment rates in rural areas, while those with dual NP-CNM certification have a higher employment rate in urban areas. Among those certified solely as NPs and employed in advanced practice, 94.8% reported that their job title was “nurse practitioner” in 2017. Among those dual certified, 20.1% had the job title of NP and 74.1% had the job title of CNM. Figure A3.

Rural Health Center (2.5%) California’s Nurse Practitioners: How Scope of Practice Laws Impact Care 15 Those in NP jobs were asked about the insurance coverage of their patients (Table A4); 23.4% of NPs think more than half of their patients are insured by Medicare, 28.1% report more than half of their patients are insured by Medicaid, and 14.1% believe more than half of their patients are uninsured. NPs who live in rural regions are more likely to report that more than half of their patients are uninsured, at 19.3%. NPs who provide primary care at least half of their time are more likely to report that more than half their patients are insured by Medicaid (35.2%) or Medicare (26.6%), or be uninsured (19.3%). More than three-quarters of NPs reported that their practices are currently accepting Medicare fee-for-service patients, 69.4% are currently accepting Medicaid patients, and 53.8% are currently accepting uninsured patients. Nurse practitioners can be recognized by private insurance companies as primary care providers. Only 31.3% of those with an NP position report they are recognized as a primary care provider. However, more than half of rural NPs (51.2%) are primary care providers in their primary NP position. Additionally, 41.6% of those who report they spend at least half their time providing primary care are recognized as primary care providers by private insurance companies. Research teams from several institutes have examined the caseloads and roles of NPs as compared with physicians. One study reported that NP and PA visits in community health centers are more often for chronic disease management and preventive care,53 and another reported that NPs are more likely to provide patient education within community health centers.54 Table A4.

California Health Care Foundation 16 Pipeline of NPs into the Workforce California has 23 NP education programs, most of which are in the Los Angeles and San Francisco Bay areas (Figure A5). There are only 2 programs in the San Joaquin Valley and none north of Sacramento or in the Central Coast region. In 2017, there were 1,744 new California certificates issued to NPs in the state. The number of graduates has nearly tripled since 2007, when there were 597 graduates. Similar growth has been reported nationally; approximately 23,000 people completed NP education programs in the US in the 2015 –16 year,55 which is more than three times the 6,611 graduates in 2003.56 There has been a shift in the types of initial education completed by NPs and CNMs over time (Figure  A6, page  18). Prior to 1980, most NPs received their initial education from nondegree certificate-granting programs. These programs have declined to a negligible share of programs, while master’s degree programs have become the dominant initial education, with more than 90% of initial NP education at this level. There also has been growth in the share of initial NP education from doctoral programs, almost entirely due to the emergence and growth of doctor of nursing practice (DNP) programs since 2004, when the American Association of Colleges of Nursing recommended that the DNP become the standard for initial APRN education.

Hemani et al. published a study in 1999 reporting that NPs were more likely to order tests and referrals than physicians, including ultrasound, CT, MRI, urinalysis, and thyroid function tests. However, this study had two main shortcomings: First, it had a small sample of only 450 patients cared for by nine NPs, 35 residents, and 10 attending physicians; second, tests were attributed to the primary care provider of record, who may not have been the person who ordered the test. A second study published in 2015 by Hughes, Jiang, and Duszak analyzed Medicare data and reported that NPs and PAs order more imaging services than primary care physicians, although the difference was only 0.3% for new patients and 0.2% for established patients. Subanalyses of patients with low back pain and acute respiratory tract infection found no difference and lower rates, respectively. The analysis did not identify whether NPs and PAs were in specialty practices, and thus the providers’ clinical foci are not strictly comparable. 42. B. Lowery, E. Scott, and M.
