Physician assistants and Title VII support

Physician Associates/Assistants in Primary Care: Policy and Value

Since the new century, primary care physician supply has worsened. Analysts predict that health service demand in the United States will grow faster than physician supply. One strategy is the utilization of physician assistants/associates (PAs). Most PAs work full-time, and approximately one quarter are employed in family medicine/general medicine. PAs deliver primary care services in a team-oriented fashion in a wide variety of settings, including private health systems and community health centers. One fifth work in rural and medically underserved areas. Together PAs and nurse practitioners provide approximately one third of the medical services in family medicine, urgent care, and emergency medicine.

American health workforce policy and PAs: A brief history

ABSTRACT

Health workforce policy in the United States from the mid-1970s has been strongly influenced by perceptions of the adequacy of the physician supply and its relationship to physician assistants/associates (PAs) and NPs. During the 1980s, a series of inaccurate reports by the federal government mistakenly warned of an impending physician surplus and shaped policy decisions for decades. In spite of perceptions of a physician surplus, the PA profession expanded rapidly in the 1990s. Projections of the adequacy of the physician supply changed to a shortage in the first decade of this century and the PA component of the healthcare workforce continued to expand. During the past decade, the Association of American Medical Colleges has employed microsimulation modeling expertise to project the extent of physician shortages, an effort that initially failed to incorporate the contributions of PAs and NPs in the workforce. Although current projection models include the contributions of PAs and NPs, the substitution ratios used are notably low. Specifically, PA and NP productivity effort was set roughly at one-quarter to one-half that of the physician. PAs and NPs make up a substantial contingent within the US healthcare workforce and should be included fully in future workforce projection estimates. This article provides policy recommendations for the advancement of PA contributions to the delivery of medical care.

The PA profession in the 1990s

ABSTRACT

History is rarely linear, and nowhere is this more evident than the US physician assistant/associate (PA) movement (1965-2021). The 1990s stand out as pivotal years for the PA profession, marked by advances that shaped the profession, experiments in primary care delivery, sex equity, the Balanced Budget Act, and national policy errors in predicting a physician surplus. Rapid growth followed program expansion, doubling from 57 in 1993 to 120 by 1999. By the end of the decade, all states had advanced PA-enabling legislation with broad-based prescribing. During this era, PA-focused research moved from descriptive to predictive, an official journal emerged in 1988, the Accreditation Review Commission on Education for the Physician Assistant became independent, and the American Academy of Physician Associates helped shape federal health policy. Also during this period, the profile of PAs shifted from older males to younger females with important sociological implications in leadership and career development. Notable milestones included national recognition of PAs as Medicare-eligible providers, direct commissioning in the military, and employment surges in the Veterans Health Administration and US Public Health Service. Not least of all this was a time of role shifts toward specialized medicine and surgery.

Physician Assistants Employed by the Federal Government

OBJECTIVE

Physician assistants (PAs) are health professionals who have received advance medical training and are licensed to diagnose illness, develop and manage treatment plans, prescribe medications, and serve as principal health care provider. Although the U.S. federal government is the largest single employer of PAs, at the same time little is known about them across the wide array of diverse settings and agencies. The objective of this project was to determine the census of PAs in federal employment, their location, and personal characteristics. This included approximating the number of uniformed PAs. Taking stock of a unique labor force sets the stage for more granular analyses of how and where PAs are utilized and are deployed.

METHODS

No one central database identifies all federally employed PAs. To undertake this project, three sources were examined. Data were derived from the U.S. Office of Personnel Management and the National Commission on Certification of Physician Assistants. Uniformed PA numbers were the result of networking with senior chiefs in the military services and the U.S. Public Health Service. The data were collolated and summarized for comparison and discussion.

RESULTS

As of 2018, approximately 5,200 PAs were dispersed in most branches and agencies of the government that provide health care services, including the Departments of Defense, Veterans Affairs, Health and Human Services, Justice, and Homeland Security. Federally employed PAs are civil servants or hold a commission in the uniformed services (ie, Army, Navy, Air Force, Coast Guard, and Public Health Service). Most PAs are in clinical roles, although a few hundred are in management positions. Approximately 81% of civilian PAs have had less than 15 years of federal employment.

CONCLUSION

The diverse utilization and deployment of PAs validate the importance of the role they serve as medical professionals in the federal government. From 2008 to 2019, PA employment in the federal government grew by approximately 50% supporting the forecast that substantial national PA growth is on track.

PA job availability in primary care during 2014 and 2016

OBJECTIVES

The objective of this project was to evaluate demand for PAs by examination of job postings. We compared proportions of PAs in primary care with proportions of job postings in primary care in 2014 and 2016 and described job postings for PAs by specialty in 2014 and 2016.

METHODS

Internet job postings for PAs supplied by Burning Glass Technologies were evaluated for practice specialty. Job postings were compared with existing filled positions by specialty as reported by the National Commission for the Certification of Physician Assistants.

RESULTS

In both years, more than 25% of PAs in practice were in primary care and fewer than 20% of job openings were in primary care. More than half of postings were in medical and surgical subspecialties.

CONCLUSIONS

Our findings provide insights into which specialties have emerging high demand for PAs. The demand for PAs appears to remain much stronger for specialty jobs than for primary care jobs.

Physician Assistant Educational Research: 50 Years On

The physician assistant (PA) profession began as an experiment in medical education. Initial research on the PA profession was performed primarily by health service researchers and medical educators who sought to measure the impact of the introduction of early PAs into practice. The introduction of PAs, health care providers who shared the practice of medicine with physicians, was a revolutionary step in health workforce policy, and its impact became a relevant topic of investigation. Research has not been a high priority in many PA programs, and the amount of research on PA education has been limited. This article traces periods of activity and contributions in PA educational research over the past 50 years and discusses prospects for the future of research in PA education.

Expansion of Physician Assistant Education

Physician assistant (PA) educational programs were created in the 1960s to prepare a new type of health care practitioner. Physician assistant programs began as experiments in medical education, and later, they proved to be highly successful in preparing capable, flexible, and productive clinicians. The growth of PA educational programs in US medical education-stimulated by grants, public policy, and anticipated shortages of providers-has gone through 3 distinct phases. At present, such programs are in the midst of the third growth spurt that is expected to continue beyond 2020, as a large number of colleges and universities seek to sponsor PA programs and attain accreditation status. Characteristics of these new programs are described, and the implications of the current expansion of PA education are examined.

PA and NP productivity in the Veterans Health Administration

This study assessed the 2014 clinical productivity of 5,959 physician assistants (PAs) and nurse practitioners (NPs) in the US Department of Veterans Affairs' Veterans Health Administration (VHA). Total work relative value units divided by the direct clinical full-time equivalent measured annual productivity, and correlated factors were examined using weighted analysis of variance. PAs and NPs in adult primary care roles were more productive than those in other specialties. Both providers were more productive in rural than in nonrural settings and less productive in teaching than nonteaching hospitals. Men were slightly more productive than women but age and years of VHA employment were not correlates of productivity. PAs were more productive when their scope of practice allowed significant autonomy; NP productivity was unaffected by supervisory requirements. PAs and NPs are an important component of the VHA provider workforce, and their productivity correlates with a number of factors. More organizational research is necessary to better understand the contributing roles PAs and NPs provide in a rapidly evolving, vertically integrated, national health delivery system.

The contributions of physician assistants in primary care systems

Shortages of primary care doctors are occurring globally; one means of meeting this demand has been the use of physician assistants (PAs). Introduced in the United States in the late 1960s to address doctor shortages, the PA movement has grown to over 75,000 providers in 2011 and spread to Australia, Canada, Great Britain, the Netherlands, Germany, Ghana and South Africa. A purposeful literature review was undertaken to assess the contribution of PAs to primary care systems. Contemporary studies suggest that PAs can contribute to the successful attainment of primary care functions, particularly the provision of comprehensive care, accessibility and accountability. Employing PAs seems a reasonable strategy for providing primary care for diverse populations.

National trends in the United States of America physician assistant workforce from 1980 to 2007

BACKGROUND

The physician assistant (PA) profession is a nationally recognized medical profession in the United States of America (USA). However, relatively little is known regarding national trends of the PA workforce.

METHODS

We examined the 1980-2007 USA Census data to determine the demographic distribution of the PA workforce and PA-to-population relationships. Maps were developed to provide graphical display of the data. All analyses were adjusted for the complex census design and analytical weights provided by the Census Bureau.

RESULTS

In 1980 there were about 29,120 PAs, 64% of which were males. By contrast, in 2007 there were approximately 97,721 PAs with more than 66% of females. In 1980, Nevada had the highest estimated rate of 40 PAs per 100,000 persons, and North Dakota had the lowest rate (three). The corresponding rates in 2007 were about 85 in New Hampshire and ten in Mississippi. The levels of PA education have increased from less than 21% of PAs with four or more years of college in 1980, to more than 65% in 2007. While less than 17% of PAs were of minority groups in 1980, this figure rose to 23% in 2007. Although nearly 70% of PAs were younger than 35 years old in 1980, this percentage fell to 38% in 2007.

CONCLUSION

The trends of sustained increase and geographic variation in the PA workforce were identified. Educational level, percentage of minority, and age of the PA workforce have increased over time. Major causes of the changes in the PA workforce include educational factors and federal legislation or state regulation.

A legislative history of federal assistance for health professions training in primary care medicine and dentistry in the United States, 1963-2008

This article reviews the legislative history of Title VII of the United States Public Health Service Act. It describes three periods of federal support for health professions training in medicine and dentistry. During the first era, 1963 to 1975, federal support led to an increase in the overall production of physicians and dentists, primarily through grants for construction, renovation, and expansion of schools. The second period, 1976 to 1991, witnessed a shift in federal support to train physicians, dentists, and physician assistants in the fields of primary care defined as family medicine, general internal medicine, and general pediatrics. During this era, divisions of general internal medicine and general pediatrics, and departments of family medicine, were established in nearly every medical and osteopathic medical school. All three disciplines conducted primary care residencies, medical student clerkships, and faculty development programs. The third period, 1992 to present, emphasized the policy goals of caring for vulnerable populations, greater diversity in the health professions, and curricula innovations to prepare trainees for the future practice of medicine and dentistry. Again, Title VII grantees met these policy goals by designing curricula and creating clinical experiences to teach care of the homeless, persons with HIV, the elderly, and other vulnerable populations. Many grantees recruited underrepresented minorities into their programs as trainees and as faculty, and all of them designed and implemented new curricula to address emerging health priorities.This article is part of a theme issue of Academic Medicine on the Title VII health professions training programs.
