The birth and evolution of the physician assistant profession.

The PA profession was born out of necessity.  Facing a national shortage of physicians and a population boom after World War, the United States was hard-pressed to meet the medical needs of those in need. The inception of the Physician Assistant (PA) profession was a response to the scarcity of physicians and the surge in population after the Second World War. Dr. Eugene Stead, Jr., the Chairman of the Department of Medicine at Duke University, recognized that Navy Hospital Corpsmen, who had provided indispensable medical care during the war, were left without a venue to apply the knowledge, and experience they had acquired. In October 1965, Dr. Stead established a Physician Assistant program at Duke University’s Department of Medicine, which provided a curriculum to supplement the clinical knowledge of these Corpsmen. Four Navy corpsmen enrolled in the program, and three graduated.


Subsequently, Duke University established the Department of Community Health Sciences and appointed Dr. Harvey Estes, Jr. as the chairman. Dr. Estes took over the PA program, and on October 6, 1967, the first three PAs, namely Kenneth F. Ferrell, Victor H. Germino, and Richard J. Scheele, graduated from the program. Notably, in 1970, the Duke PA program graduated the first female, Joyce Nichols, a nurse at Duke Hospital. Joyce created history by becoming not only the first female PA but also the first African American to join the PA profession.


During the 1970s, a postgraduate residency program in family medicine was implemented, leading to a transformation of the clinics at Duke Hospital into centers of excellence for training MD/PA healthcare teams. Dr. Estes’s unwavering commitment to promoting the new philosophy of healthcare delivery through extensive writing and nationwide travel significantly contributed to the acceptance of this new profession within the medical community. Consequently, accreditation standards were established, and national certification standards were put in place. This evolution of healthcare delivery has been a remarkable achievement that continues to impact the medical profession positively.


The success of Duke University’s initial Physician Assistant (PA) program paved the way for the establishment of similar programs at other institutions throughout the United States. In 1967, the American Medical Association (AMA) officially recognized the PA profession, thereby granting it a degree of legitimacy and acceptance within the medical community. The AMA’s recognition was instrumental in promoting the growth and acceptance of PAs as valuable members of the healthcare team.


The early contributions of Physician Assistants (PAs), particularly those from the pioneering Duke program, have been instrumental in improving healthcare delivery. Their services have proved invaluable in bridging the gap in healthcare access for those living in rural and underserved areas, catering to disadvantaged populations, and enhancing patient care and satisfaction. Moreover, their ability to perform a wide range of medical tasks has not only alleviated the workload of physicians but has also resulted in the improvement of the overall quality of care.


The profession of Physician Assistants (PAs) has experienced several significant legal and regulatory developments since its inception that have impacted its scope of practice. Although state laws and regulations differ, many have expanded the autonomy and responsibilities of PAs. For example, in several states, PAs have been granted the ability to practice independently or with a collaborative agreement, rather than direct physician supervision. These changes have been instrumental in increasing the availability of healthcare services, particularly in areas with a shortage of physicians. As a result, PAs have become an important part of the healthcare workforce, and their role in providing quality healthcare to patients has been increasingly recognized.


The education provided to Physician Assistants (PAs) has undergone significant changes in response to the evolving healthcare industry. Initially, PA programs were typically of a shorter duration, lasting two years and leading to a certificate or diploma. However, contemporary PA programs are commonly master’s degree programs that span approximately 27 months. These programs provide a comprehensive education in medical sciences and clinical skills, thereby equipping PAs to undertake increasingly complex roles in diverse areas such as patient care, research, education, and healthcare administration.


The Physician Assistant (PA) profession has been strengthened and advanced by various professional organizations, such as the American Academy of Physician Assistants (AAPA) and the Physician Assistant Education Association (PAEA). These organizations have been instrumental in advocating for PAs on issues regarding legislation, reimbursement, and professional growth. The AAPA, in particular, has played a significant role in promoting the interests of PAs on a national level and advancing their role within the healthcare delivery system.


The PA profession has increasingly become a vital component of the healthcare system, and these organizations have been supportive of the PA’s role in providing quality healthcare services. Through its advocacy efforts, AAPA has facilitated the recognition of PAs as valuable members of the healthcare team. The organization’s initiatives have also helped to promote the use of PAs in various medical specialties, which has resulted in increased access to care for patients.


Furthermore, the PAEA has been instrumental in advancing the PA education system. The association has been actively involved in developing an effective curriculum that is geared toward producing competent and skilled PAs. The organization has also been supportive of research and innovation in the field of PA education. In essence, the AAPA and the PAEA have been crucial in promoting the growth and development of the PA profession. Their efforts have resulted in the recognition of PAs as essential healthcare providers, contributing significantly to the delivery of quality healthcare services.


The inception of the PA profession constitutes a pivotal moment in the annals of healthcare in the United States. Dr. Eugene A. Stead Jr. demonstrated a visionary approach to addressing the paucity of primary care providers, resulting in the creation of a novel healthcare role that continues to thrive and evolve to this day. The PA profession, emanating from a pressing need, has become an indispensable component of not only the healthcare workforce but also in the education of future physicians and physician assistants. The origin of the PA profession is a testimony to the power of innovation and the perseverance of individuals and institutions in meeting the changing healthcare needs of society.


PAs have played a vital role in providing medical aid and support to underserved communities throughout the United States. They have been instrumental in offering patient-centered care, providing comfort, hope, and assistance to individuals of all ages, while also helping them maintain their health and dignity. As the aging of the baby boomer generation and the ongoing escalation of healthcare costs continue to dominate the national discourse, the PA profession is poised to expand significantly, becoming an essential cornerstone in healthcare delivery and revolutionizing the provision of medical care.
