Characteristics of patient visits to nurse practitioners and physician assistants in hospital outpatient departments

Many authors have described differences between nurse practitioners and physician assistants. Most studies have compared physician with nonphysician providers' practice. Few studies have compared nurse practitioners and physician assistants, and none has used a national data base. This exploratory, atheoretical research examined which of the following characteristics predicted patients being seen by nurse practitioners and physician assistants: patient and hospital demographics, diagnosis, diagnostic/screening services, therapeutic services, and disposition of the visit. The data set used for analysis was the 1992 National Hospital Ambulatory Medical Care Survey. Based on a multistage probability design yielding national estimates for patient visits in hospital outpatient settings, the National Hospital Ambulatory Medical Care Survey showed that there were 2,847 weighted patient visits to either nurse practitioners or physician assistants (4.6 million patient visits using national estimates). Results of multivariate logistic regression suggest that nurse practitioners were the most likely nonphysician provider for outpatients receiving more health promotion and counseling (therapeutic) services and for those needing women's and children's services. Outpatients in rural areas predicted visits to physician assistants. As more nonphysician providers enter the work force, the results of this research may assist with understanding the utilization of nurse practitioners and physician assistants in primary care.     

The public's view of physicians' assistants and nurse practitioners: a survey of Baltimore urban residents.

This study of public attitudes toward physicians' assistants and nurse practitioners finds that the public regards the two groups of health workers as remarkably similar. A telephone survey of 2,583 households in the Baltimore, Maryland, metropolitan area indicates that about half the population have heard of a PA or NP, though only 4 per cent report receiving care from such workers. In this urban sample, respondents accepted the principle that important medical care functions can be delegated, as long as the PA or NP is considered assistant to the physician. The public reported more acceptance of tasks performed by nurse practitioners than by physicians' assistants, though the differences are small.     

Nurse practitioners and physician assistants revisited: do their practice patterns differ in ambulatory care?

The education and regulation of nurse practitioners and physician assistants would suggest unique role differentiations and practice functions between the professions. This study explored to what extent their practice patterns in primary care actually differ. It was hypothesized that the primary care services provided by nurse practitioners would tend to be women and family health services, health prevention and promotion oriented, provided to minority and socioeconomic disadvantaged patients, and less dependent on physician supervision. In contrast, the services provided by physician assistants would more likely be medical/surgical oriented; diagnostic, procedural, and technical in nature; likely to be in rural areas; and more dependent on physician supervision. The study used patient data from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey. Although some differences emerged, the argument is not compelling to suggest strong, unique, practice differences across all ambulatory care settings between the two types of nonphysician providers. It is the specific type of ambulatory setting that influences the practice pattern for both provider groups. If practice patterns are less distinctive than previously believed, more opportunities for interdisciplinary education need to be explored, and health policies that promote a discipline-specific primary care workforce may need to be reexamined.     

How HMOs structure primary care delivery

To promote a shared understanding of how health maintenance organizations (HMOs) deliver primary care, the primary care staffing strategies of 23 HMOs are described: who they use as "gatekeepers," how they use nurse practitioners (NPs) and physician assistants (PAs), their referral policies, and their views on how the scope of practice of primary care may change. The study is based on on-site interviews with senior health plan personnel, and finds wide variations in primary care strategies, from open access to primary care and loose referral policies, to tight gatekeeping systems. In network/independent practice association (IPA) model plans, provider groups and IPAs, not the HMO, often determine who provides primary care. Implications are discussed.     

Physician attitudes toward physician extenders: a comparison of nurse practitioners and physician assistants.

A survey of all physicians in the Eighth District Medical Society (Western New York) was conducted in 1975 to determine physician attitudes toward employment of and task delegation to nurse practitioners. The results of this study and one other similar study of nurse practitioners are compared to results of two previous studies examining physician attitudes toward physician assistants. It appears that physicians are somewhat more willing to employ and delegate tasks to a physician's assistant. Some correlates of physician attitudes toward each of the two types of physician extenders are also compared and discussed.     

Management of Mild-to-Moderate Osteoarthritis: A Study of the Primary Care Perspective

Abstract

Objectives: Examine the knowledge, attitudes, and practice patterns of primary care clinicians regarding the management of mild-to-moderate osteoarthritis (OA). Design: Case vignette-based survey. Methods: A survey was distributed to 251 physicians, physician assistants (PAs), and nurse practitioners (NPs) in the primary care setting. The survey assessed practice patterns in the management of patients with mild-to-moderate OA, as well as attitudes toward guidelines and future educational topics that may be of benefit to the clinician. Results: We found that primary care clinicians are most likely to treat mild-to-moderate OA with an oral nonsteroidal anti-inflammatory drug regimen. Patients with initial or recurrent OA were “very likely” to be recommended to a physical therapy maintenance program. Two-thirds of respondents claimed to be unfamiliar with Osteoarthritis Research Society International guidelines for OA management. Conclusion: This study reflects the need for further education for primary care physicians, NPs, and PAs on the management of OA.     

Nurse practitioner, nurse midwife and physician assistant attitudes and care practices related to persons with HIV/AIDS

Although multiple studies of nurses' attitudes toward people living with HIV/AIDS (PLWAs) can be found in the literature, little is known about the attitudes, beliefs and practices of nurse practitioners (NPs), certified nurse midwives (CNMs), and physician assistants (PAs). A survey including a 21-item AIDS Attitude Scale measuring the constructs of Avoidance and Empathy was sent to 1,291 NPs, CNMs and PAs in Louisiana, Arkansas and Mississippi to describe their attitudes and care practices related to PLWAs. Respondents who were more comfortable treating PLWAs had significantly lower avoidance scores and significantly higher empathy scores than respondents with lower comfort levels in providing care. Greater than 80% of respondents indicated that they would provide health care to HIV-infected individuals. Respondents who referred HIV/AIDS patients for all care did so primarily due to lack of experience with HIV and the availability of more experienced providers. Avoidance and empathy scores were not found to be significantly associated with referral for care. This study suggests that this group of providers has relatively low avoidance and high empathy toward PLWAs and is willing to care for HIV-infected individuals.     

The Acute Care Nurse Practitioner in Collaborative Practice

Nurse-physician relationships remain, for the most part, hierarchical in nature. A hierarchical structure allows the person at the top, most notably the physician, the highest level of authority and power for decision making. Other health care providers are delegated various tasks related to the medical plan of care. One role of nonmedical health care providers, including nurses, is to support the medical plan of care and increase the productivity of physicians. Medical centers have house staff, usually interns and residents, who work collaboratively with the attending physicians in care delivery. At one medical center, a shortage of medical house staff for internal medicine prompted the development and evaluation of an alternative service. The alternative service utilized master prepared, certified nurse practitioners on a nonteaching service to provide care for selected types of medical patients. Physicians consulted with nurse practitioners, but retained decision-making authority concerning patient admission to the service. This paper describes the development and evaluation of an alternative service based on a collaborative practice model and the role of nurse practitioners working under such a model. Discussion includes suggestions for process guideline development for organizations that want to improve collaborative practice relationships between unit nursing staff, nurse practitioners, and physicians.     

Acceptance of Nurse Practitioners and Physician Assistants in Meeting the Perceived Needs of Rural Communities

ABSTRACT Nurse practitioners and physician assistants have provided a partial solution to the shortage of primary care services in medically underserved rural areas. This paper describes the results of a study exploring community acceptance of nurse practitioners and physician assistants in rural medically underserved areas. Community acceptance in the context of this study implies not only satisfaction with care received, but also willingness of the community to support NP/PA practice through its infrastructure and encourage members to initially seek and continue to receive care from an NP or PA. Five focus groups were conducted in each of five rural medically underserved communities. The two most pervasive findings were the lack of previous exposure to NPs and PAs and the general belief that NPs and PAs would be accepted in these communities if certain conditions could be met. The theme of conditional acceptance included both personal and system factors. Personal factors included friendliness, competence, willingness to enter into the life of the community, and the ability to keep information confidential. System factors considered critical for acceptance included service type, integration with the existing health care system, cost, geographic proximity, and availability. The results of this study offer insight into community attitudes and suggest marketing strategies for those who plan to introduce NP or PA services into rural communities.     

Nurse practitioners and physicians: a collaborative practice

The rapid evolution of health care delivery within the United States has created increased opportunities for nurse practitioners (NPs) to work in a variety of challenging advanced practice roles and to impact the quality of health care. The NP role was originally developed to meet a perceived shortage of primary care physicians, especially for underserved populations. Today, NPs work in various fields, such as geriatrics and women's and family health care, as well as in various systems such as private practice and health maintenance organizations. Effective collaboration with physician colleagues will promote improved communication, health care management, and positive health outcomes. Barriers to effective collaboration are reimbursement, territorialism, and role confusion on part of the health care team and the general public.     

Skill mix change between physicians,nurse practitioners,physician assistants,and nurses in nursing homes: A qualitative study

Nursing home physicians face heavy workloads, because of the aging population and rising number of older adults with one or more chronic diseases. Skill mix change, in which professionals perform tasks previously reserved for physicians independently or under supervision, could be an answer to this challenge. The aim of this study was to describe how skill mix change in nursing homes is organized from four monodisciplinary perspectives and the interdisciplinary perspective, what influences it, and what its effects are. The study focused particularly on skill mix change through the substitution of nurse practitioners, physician assistants, or registered nurses for nursing home physicians. Five focus group interviews were conducted in the Netherlands. Variation in tasks and responsibilities was found. Despite this variation, stakeholders reported increased quality of health care, patient centeredness, and support for care teams. A clear vision on skill mix change, acceptance of nurse practitioners, physician assistants, and registered nurses, and a reduction of legal insecurity are needed that might maximize the added value of nurse practitioners, physician assistants, and registered nurses.     

Nurse practitioner liability and authority

Nurse practitioners are being held to a higher professional standard. No longer can nurses assume that their practice is protected by physicians and hospitals. Current trends indicate that nurse practitioners are accountable for their actions and are liable for malpractice. Legislation regulating the practice of nurse practitioners varies from state to state; differing opinions among nurses, physicians, and legislators account for some of these variances. The ultimate goal of the health care professions is the delivery of safe, effective, cost-efficient health care. Nurse practitioners are helping to achieve this goal.     

Central Line–Associated Bloodstream Infections and Advanced Practice Providers: Identifying Opportunities for Prevention Efforts

Central venous catheters can be a vital part of patient care in the hospital setting but are at high risk of infection. Central line–associated bloodstream infections pose a high risk of morbidity, mortality, and increased hospital costs. The purpose of this project is to assess the practices and learning needs of advanced practice providers (nurse practitioners and physician assistants) in the provision of evidence-based care to patients with central venous catheters in the hospital setting. This can guide further educational initiatives for central line–associated bloodstream infection prevention.     

Ovarian Cancer Knowledge Among Advanced Providers in a University Setting

Ovarian cancer is usually diagnosed at a late stage of the disease. Nurse practitioners and physician assistants are often the first contact, and awareness of the signs and symptoms of the disease may improve diagnosis and outcome. A knowledge survey of risk factors and symptoms was distributed to all nurse practitioners and physician assistants at a university health system. Knowledge of signs and symptoms of ovarian cancer in these providers was low. Early satiety, abdominal fullness, and urinary urgency were frequently missed by both groups. Our findings illustrate the need for the development and availability of materials to address knowledge gaps.     

The changing division of labour between nurses and nursing assistants in New Brunswick

BACKGROUND: In 1989, the professional nursing organization that represents nurses in New Brunswick adopted baccalaureate entry to practice in nursing. This decision coincided with a major restructuring of provincial health care. Consequently, there has been a reorganization of health care worker roles which affects nurses and nursing assistants. AIM: This paper explores the changing division of labour between nurses and nursing assistants in the province of New Brunswick, Canada. METHODS: The study used archival material, from the period 1978-1990, of three nursing organizations that played a significant role in initiating baccalaureate entry to practice. Interviews with 19 key people involved in the decision to upgrade nurse education were conducted. Data from the archival material and interviews were analysed jointly. FINDINGS: There are ongoing tensions between nurses and nursing assistants. Although nurses would like a support worker, they remain ambiguous about the role of nursing assistants in health care and which tasks should be delegated to this group. Nursing leaders are concerned about the ease with which some patient-related tasks are moved to nursing assistants. In the past, these concerns have led nursing leaders to attempt to limit nursing assistant responsibilities through both legislative means and ways of organizing nursing labour (primary nursing). As a result of health care reforms and baccalaureate entry to practice for nurses, nursing assistant responsibilities are currently expanding. CONCLUSION: Upgrading nurse education, which came into effect in 1996 with the closure of diploma schools in New Brunswick, is likely to entrench the role of nursing assistants in health care because of the economic value of their work during a period of restructuring and rationalization of health care.     

Gender and the attribution of the nurse practitioner and physician status

The purpose of this study was to discover whether sex-role sterotypes were used to identify members of two professions, nurse practitioners and physicians. Participants reported whether they believed a videotaped health care provider was a physician or a nurse practitioner. Results showed that male providers tended to be identified as physicians, whereas female providers tended to be identified as nurse practitioners. Findings indicate that understanding and enactment of the nurse practitioner and physician roles are still affected by gender issues and that both physicians and nurse practitioners remain subject to the force of sex-role stereotypes.     

Practice patterns of underrepresented minority nurse practitioners in New York state, 2000

Using data collected from a sample of 1,319 nurse practitioners (NPs) in New York state in 2000, differences in practice patterns by race and ethnicity were identified. NPs from underrepresented minority (URM) groups were more likely than non-URM NPs to work in hospitals, community health centers, and schools but less likely to work in physician offices and NP practices. URM NPs were also more likely to report a specialty certification in women's health. Several different measures of primary care provision were examined, with URM NPs substantially more likely to meet all four measures of primary care practice than non-URM NPs. Finally, URM NPs were more likely than non-URM NPs to practice in federally designated health profession shortage areas.
