Issues Surrounding the Distribution and Utilization of Nurse Nonphysician Providers in Rural America*

ABSTRACT: The cost and quality of health care is an ever-increasing concern. Responsible people are looking for logical solutions. One solution is the increased involvement of nurse practitioners and certified nurse midwives in the delivery of health care services to patients. This paper reviews the supply, education, and responsibilities of nurse practitioners and certified nurse midwives, government studies of the need for nonphysician providers, the cost-effectiveness of health care delivered by nurse practitioners and certified nurse midwives, and impediments to practice.     

Education of Physician Assistants, Nurse Midwives, and Nurse Practitioners for Rural Practice

Physician assistants, nurse midwives, and nurse practitioners have been described as a vital and unique solution to the problem of providing adequate access to high quality health care for many Americans. Each of these classifications of health care providers has been accepted as separate professions with their own standards and identities. Their curricula and educational pathways have developed into clearly distinguishable educational tracks that complement the larger disciplines of nursing and medicine. Physician assistants, nurse midwives, and nurse practitioners have been singled out in federal legislation for their potential contribution to underserved rural communities (e.g., the Rural Health Clinics Services Act of 1977 and its subsequent amendments). This designation is partly due to the fact that certified nurse midwives, nurse practitioners, and physician assistants traditionally chose to practice in rural, underserved areas, and because their skills and practice structures were well matched to the needs and resources of rural areas. That pattern of practice, however, appears to have changed and the distribution of these practitioners has begun to resemble the distribution of physicians and other clinicians with heavy concentrations in urban areas and a growing shortage in rural and underserved areas.     

Midwifery care, social and medical risk factors, and birth outcomes in the USA

STUDY OBJECTIVE: To determine if there are significant differences in birth outcomes and survival for infants delivered by certified nurse midwives compared with those delivered by physicians, and whether these differences, if they exist, remain after controlling for sociodemographic and medical risk factors. DESIGN: Logistic regression models were used to examine differences between certified nurse midwife and physician delivered births in infant, neonatal, and postneonatal mortality, and risk of low birthweight after controlling for a variety of social and medical risk factors. Ordinary least squares regression models were used to examine differences in mean birthweight after controlling for the same risk factors. STUDY SETTING: United States. PATIENTS: The study included all singleton, vaginal births at 35-43 weeks gestation delivered either by physicians or certified nurse midwives in the United States in 1991. MAIN RESULTS: After controlling for social and medical risk factors, the risk of experiencing an infant death was 19% lower for certified nurse midwife attended than for physician attended births, the risk of neonatal mortality was 33% lower, and the risk of delivering a low birthweight infant 31% lower. Mean birthweight was 37 grams heavier for the certified nurse midwife attended than for physician attended births. CONCLUSIONS: National data support the findings of previous local studies that certified nurse midwives have excellent birth outcomes. These findings are discussed in light of differences between certified nurse midwives and physicians in prenatal care and labour and delivery care practices. Certified nurse midwives provide a safe and viable alternative to maternity care in the United States, particularly for low to moderate risk women.     

A rural-urban comparative study of nonphysician providers in community and migrant health centers.

This is a study of the employment of nonphysician providers--nurse practitioners, physician assistants, and certified nurse midwives--in both rural and urban Community and Migrant Health Centers and of factors associated with their employment, based on a 1991 national survey of 383 Centers. Results of the survey suggest that nonphysician providers, in particular nurse practitioners and certified nurse midwives, primarily serve as physician substitutes, and are more likely to be employed by Centers that are larger and have affiliations with nonphysician provider training programs. Rural or urban location is not significantly related to the employment of nonphysician providers after controlling for center size. The fact that rural centers employ fewer nonphysician providers than urban centers can primarily be accounted for by their relatively small size, rather than a lack of interest. These findings demonstrate that the use of nonphysician providers is an important way both to achieve cost containment and improve access to primary care for those residing in medically underserved areas.     

Primary health care and the Midwest flood disaster.

The Midwest flood disaster of 1993 ravaged communities across a 9-State area. Homes were destroyed, roads closed, and services disrupted. Economic costs, including loss of revenue from farming and loss of jobs, are estimated at more than $1 billion. Even as people continue to rebuild their lives 1 year later, renewed flooding has occurred in some areas. A community-based primary health care system can be described as a system of services that (a) offers all members of a family continuous, comprehensive, quality health services throughout their lives; (b) includes case management and coordinated referrals to other related services when necessary; (c) is usually provided by family practitioners, general internists, general pediatricians, obstetricians-gynecologists, nurse practitioners, certified nurse midwives, and physician assistants; and (d) has community involvement in the development and management of the system to assure that it meets the changing needs and the diversity of the people it is designed to serve. This paper uses the floods to describe the impact of a disaster on primary health care services and primary health care systems. This includes changes in the demand for services (as evidenced by the frequency and type of patient visits) and the ability of the system to respond to these changes. The effect of a disaster on access to primary health care is discussed.     

Professional relationships between midwives and physicians: collaboration or conflict?

This study examines the professional relationships between midwives and physicians providing obstetrical care in Washington State. Four hundred ninety-six randomly sampled family physicians and obstetrician-gynecologists and 211 certified nurse, licensed, and lay midwives were surveyed to learn more about midwife/physician consulting relationships. Only certified nurse midwives have forged mutually satisfactory relationships with the physician community. Increased hospital-based training and practice opportunities are needed before licensed midwives can improve their professional relationships with physicians.     

The system of alignments challenging physician professional dominance: an elaborated theory of countervailing powers

Abstract The growth of managed care in the United States is altering the shape of the system of professions and is accelerating an overall decline of physician professional dominance in that system. An adequate understanding of the changing character of the system of professions demands a consideration of the interacting roles of ‘competing’ health care providers, the state, corporate and consumer forces; however, past research addressing one or more of these forces has not explicitly examined their interrelation. The countervailing powers framework provides a starting point for articulating precisely this sort of interrelation. Using data from a comparative case study of interprofessional competition between certified nurse‐midwives (CNMs) and physicians within select state policy and managed care contexts, this article extends the countervailing powers framework, illustrating how the relationships among relevant parties in the health care system can be understood as a system of alignments challenging physician professional dominance in a complex manner. Specifically, this research finds that the actions of consumers and health care administrators, coupled with state policy evolutions and the expansion of managed care, not only separately challenge physician professional dominance but also work together, as a system, to intensify interprofessional competition between certified nurse‐midwives and physicians, further undermining that dominance.     

The Determinants of Utilization of Nonphysician Providers in Rural Community and Migrant Health Centers

The use of nonphysician providers, such as nurse practitioners, physician assistants, and certified nurse midwives, in rural areas is critically important due to the continued primary care access problems. This study examines the major factors influencing the use of nonphysician providers in rural community and migrant health centers based on a 1991 national survey of the centers. This study demonstrates that the employment of nonphysician providers in rural community and migrant health centers is significantly influenced by both supply and demand factors. Among supply factors, there is a significant and positive relationship between the number of total staff and the number of nonphysician providers employed. There is a significant but inverse relationship between the number of physicians and the number of nonphysician providers employed, indicating nonphysician providers primarily serve as substitutes for physicians in rural community and migrant health centers. The supply of nonphysician providers, as measured by the number of affiliated training programs, is significantly related to the employment of nonphysician providers. The demand variable, geographic location, and the centers' staffing policies are also significant determinants of the use of nonphysician providers.     

Rural and Urban Nonphysician Providers in Georgia

Abstract: Nonphysician providers make valuable contributions to health care in rural areas. This study examines provider and practice characteristics, location preference, and reasons for location preference among Georgia nurse practitioners (NPs), certified nurse midwives, and physician assistants (PAS) (N=1,079). Data collected through a statewide survey revealed that providers were concentrated in urban areas. Rural providers tended to be older, less educated, possess fewer specialty credentials, and were employed longer than urban providers. NPs were significantly more likely to prefer smaller communities, and PAS were significantly more likely to prefer larger communities. Providers who preferred smaller communities were likely to practice in rural and urban areas, but providers who preferred larger communities were substantially more likely to practice in urban areas. Providers who preferred smaller communities were significantly more likely to mention the importance of community dynamics, while providers who preferred larger communities were significantly more likely to mention professional context.     

Texting From the Bush: Data Collection Using SMS Text Messaging in Areas of Low Network Coverage From Low-Literacy Providers

Mobile health technology, specifically Short Message Service (SMS), provides a low-cost medium to transmit data in real time. SMS has been used for data collection by highly literate and educated health care workers in low-resource countries; however, no previous studies have evaluated implementation of an SMS intervention by low-literacy providers. The Liberian Ministry of Health and Social Welfare identified a lack of accurate data on the number of pregnancies from rural areas. To capture these data from 11 rural communities in Liberia, 66 low-literate traditional midwives and 15 high-literate certified midwives were trained to report data via SMS. Data were reported via a 9-digit code sent from Java-based mobile phones. Study aims included determining the following components of SMS transmission: success rate, accuracy, predictors of successful transmission, and acceptance. Success rate of SMS transmission was significantly higher for certified midwives than for traditional midwives. The error rate was significantly higher for traditional midwives than for certified midwives. Years of education was the only predictor of successful SMS transmission. Traditional midwives and certified midwives accepted the intervention, although certified midwives found it easier to use. Certified midwives performed significantly better than did traditional midwives. SMS texting interventions should be targeted to health care workers with higher rates of literacy.     

Mainstreaming alternative medicine: doing midwifery at the intersection

Joining the discussion regarding the future of alternative and traditional medical practices and beliefs, the author explores how operating within the dominant sociopolitical system challenges alternative health care providers' definitions of themselves, their practices, and their systems of beliefs. Specifically, this case study articulates the experiences of one group of birth care providers (both certified nurse and nonlicensed, apprentice-trained midwives) as a web of paradox that simultaneously marginalizes parts of their occupational identity while allowing them to operate within the dominant sociopolitical system.     

Health care providers' perspectives on the provision of prenatal care to immigrants

In addition to facing barriers to health care and experiencing poor health status, immigrants to Canada and Sweden tend to have more negative birth outcomes than the native-born population, including low birth weight and perinatal mortality rates. Explored through interviews with health care professionals, including midwives, nurse practitioners, social workers and obstetrician gynaecologists, this paper evaluates their experiences in providing prenatal care to immigrants in Hamilton, Ontario, Canada. Results reveal the complexity of delivering care to immigrants, particularly with respect to expectations surrounding language, culture and type and professionalism of care. The paper concludes by discussing future research options and implications for the delivery of prenatal care to this population.

Issues confronting the new health professionals.

New health practitioners (NHPs) is a generic term referring to mid-level health workers such as physician's assistants and nurse practitioners who perform tasks traditionally within the purview of physicians. In the little over ten years since the first program to train physician assistants was initiated at Duke University, 6,500 physician's assistants (PAs) have completed formal training programs. Similarly, programs to train nurses for extended roles have prepared more than 8,500 nurse practitioners over the same decade. This paper considers the comparative achievements of these two major new health professions during the last decade and identifies eight crucial issues which may influence new health professionals in the ten years which lie ahead: (1) How many NHPs are enough? (2) What impact are NHPs making on distribution? (3) Do we know what clinical difference NHPs make? (4) Are NHPs bringing about cost control in health care? (5) What is the status of the controversy between organized medicine and nursing with regard to NHPs? (6) Are there differences between nurse practitioners and physician's assistants? (7) How are NHPs certified? and (8) Finally, can a better name than "new health practitioners" be found?     

Rural and Urban Physicians' Perceptions Regarding the Role and Practice of the Nurse Practitioner, Physician Assistant, and Certified Nurse Midwife

ABSTRACT: Context: There is a dearth of literature citing the differences in rural and urban physicians' perceptions of the role and practice of nurse practitioners, physician assistants, and certified nurse midwives (nonphysician providers). Purpose: The purpose of this study was to investigate and compare differences, if any, between rural and urban primary care physicians' perceptions of the role and practice of nonphysician providers. Results: Despite a 15.55% response rate using a mail-out survey in South Carolina, data from 681 rural and urban primary care physicians indicated that they perceived that nonphysician providers possess the necessary skills and knowledge to provide primay care to patients, are an asset to a physician's practice, free the physician's time to handle more critically ill patients, and increase revenue for the practice, but increase the risk of patient care mistakes and a physician's time in administrative duties. Urban physicians' mean scores were higher for perceiving that nonphysician providers are able to see as many patients in a given day as a physician but experience impediments in the delivery of patient care. Conclusions: Results will be used to clarify physicians' perceptions regarding the role and practice of nonphysician providers to reduce impediments to patient care access.     

Improving Care for Women with a History of Gestational Diabetes: A Provider Perspective

To identify perceived roles with regard to care for women with gestational diabetes mellitus (GDM) history and resources for improving care among women with a history of GDM from the perspective of obstetrician/gynecologists (OB/GYNs), certified nurse midwives (CNM), family practitioners, and internists. In 2010, a survey was sent to a random sample of OB/GYNs, CNM, family practitioners, and internists (n = 2,375) in Ohio to assess knowledge, attitudes, and postpartum practices regarding diabetes prevention for women with a history of GDM. A total of 904 practitioners completed the survey (46 %). Over 70 % of CNMs strongly agreed it is part of their job to help women with GDM history improve diet and increase exercise, compared with 60 % of family practitioners/internists and 55 % of OB/GYNs (p < 0.001). More OB/GYNs and CNMs identified a need for more local nutrition specialists and patient education materials, compared with family practitioners/ internists. Between 60 and 70 % of OB/GYNs and CNMs reported lifestyle modification programs and corresponding reimbursement would better support them to provide improved care. Health care providers giving care to women with GDM history have varying perceptions of their roles, however, there was agreement on resources needed to improve care.     

Patterns of health service utilization and perceptions of needs and services in rural Orissa

Despite emphasis on strengthening local health care provision, concern remains regarding the rates of utilization of state-provided services within Orissa. The reported study examined patterns of service utilization across the rural population of four districts of Orissa, with special reference to perceptions of the availability and quality of state services at the primary care level. Within the selected districts, 219 interviews were conducted across 66 villages. Households reported utilizing a wide range of health care providers, although hospitals constituted the most frequently--and primary health care centres (PHCs) the least frequently--accessed services. Private practitioners (qualified and unqualified) represented a major sector of provision. This included high rates of access by scheduled tribes and castes (running at approximately twice the rate of access to both local and PHC provision). Key factors guiding patterns of utilization were reputation of the provider, cost and physical accessibility. Local health provision through assistant nurse midwives and male health workers was generally perceived of poor quality, with the lowest rates of resolution of health problems of all service providers. The location of a sub-centre base for assistant nurse midwives within a village had no demonstrable impact on access to services. Acknowledging constraints on broader generalization, the implications of the findings for informing health policy and programming within Orissa are noted. This includes support for current efforts to strengthen the capacity of PHC and sub-centre level provision within the state, and acknowledgement of the potentially growing role of effectively regulated private provision in meeting the needs of the rural poor.     

One state's response to the malpractice insurance crisis: North Carolina's Rural Obstetrical Care Incentive Program.

In the period 1985-89, there was a severe drop in obstetrical services in rural areas of North Carolina, partly because of rising malpractice insurance rates. The State government responded with the Rural Obstetrical Care Incentive (ROCI) Program that provides a malpractice insurance subsidy of up to $6,500 per participating physician per year. Enacted into law in 1988, the ROCI Program was expanded in 1991, making certified nurse midwives eligible to receive subsidies of up to $3,000 per year. To participate, practitioners must provide obstetrical care to all women, regardless of their ability to pay for services. Total funding for the program has increased from $240,000 to $840,000, in spite of extreme budgetary constraints faced by the State. The program and how its implementation has maintained or increased access to obstetrical care in participating counties are described on the basis of site visits to local health departments in participating counties and data from the North Carolina Division of Maternal and Child Health. The program is of significance to policy makers nationwide as both a response to rising malpractice insurance rates and reduced access to obstetrical care in rural areas, and as an innovative, nontraditional State program in which the locus of decision making is at the county level.     

Reproductive health services in rural Washington State: scope of practice and provision of medical abortions, 1996-1997

OBJECTIVES: This study explored reproductive health care in rural Washington State, reasons given by providers for not offering abortions, and providers' willingness to use medical abortifacients. METHODS: Physicians, midwives, nurse practitioners, and physician assistants in rural Washington completed an inventory of reproductive health services that they provide, whether and why they do not perform abortions, and whether they would use medical abortifacients. RESULTS: Of the respondents, 89.2% reported providing reproductive health care. Only 1.2% reported performing surgical abortions, and 26.1% indicated that they would probably prescribe medical abortifacients. CONCLUSIONS: Few providers offer surgical abortions in rural Washington. Greater numbers report a willingness to prescribe medical abortifacients.     

Primary Care Professionals’ Feedback on Smiles for Life Curriculum

To assess the value of Smiles for Life: A National Oral Health Curriculum (SFL) in influencing oral health practices of primary care professionals (PCPs). The National Maternal and Child Oral Health Resource Center’s Partnership for Integrating Oral Health Care into Primary Care (PIOHCPC) project is working with five project teams in Georgia, Illinois, Maryland, Michigan, and Rhode Island that are integrating interprofessional oral health core clinical competencies into primary care practice. The competencies were developed to facilitate change in the clinical practice of PCPs working with vulnerable or underserved populations that lack or have limited access to oral health care. An initial PIOHCPC project requirement was for PCPs (physicians, nurse practitioners, nurse midwives, nurses) to complete at least two SFL courses based on their project population of focus (eg, pregnant women, children, adolescents). The curriculum consists of the following courses: Course 1: Relationship of Oral and Systemic Health; Course 2: Child Oral Health; Course 3: Adult Oral Health; Course 4: Acute Dental Problems; Course 5: Oral Health for Women: Pregnancy and Across the Lifespan; Course 6: Caries Risk Assessment, Fluoride Varnish, and Counseling; Course 7: The Oral Exam; and Course 8: Geriatric Oral Health. Three months after completion of the SFL courses, a 10-question feedback form was sent to PCPs. PCPs working in primary care settings (community health centers, local health department, medical center women’s health clinic) serving pregnant women, children, and adolescents who completed at least two SFL courses as part of the PIOHCPC project. Thirteen PCPs (three physicians, three nurse practitioners, three nurse midwives, four nurses) completed the feedback form. One hundred percent of respondents strongly agreed/agreed that SFL courses (1) reinforced the importance of oral health to a patient’s overall health and well-being, (2) increased their awareness of and familiarity with oral health issues in their patients, and (3) increased their confidence in integrating oral health care into primary care. Seventy-seven percent of respondents strongly agreed/agreed that SFL courses helped reduce barriers to incorporating oral health care into primary care. Sixty-two percent of respondents strongly agreed/agreed that integrating oral health care into primary care improved their patients’ oral health outcomes. The majority (ranging from 85 to 100 percent) of PCPs strongly agreed/agreed that SFL courses helped them integrate the interprofessional oral health core clinical competencies into primary care. Three months after completing SFL courses, PCPs indicated that the curriculum had a positive influence on oral health practices in the primary care setting. These findings are consistent with a 2017 study that examined SFL influence on clinical practice and found that the curriculum positively influenced oral health practices in the primary care setting. Additional feedback could be gathered 1 year post-training to assess retention of PCPs’ practices related to integrating oral health care into primary care. Oral health training is essential for enhancing PCPs’ knowledge and practices related to integrating oral health care into primary care. To respond to the need to integrate oral health care into primary care, SFL should be considered as a training for PCPs. Health Resources and Services Administration.
