What is a physician assistant?

January 25, 2023 at 1:12 PM

A physician assistant (PA) is a healthcare professional who is licensed to practice medicine under the supervision of a physician. PAs can perform many of the same tasks. They typically work in a variety of medical settings, such as primary care clinics, hospitals, and specialty practices. PAs must graduate from an accredited PA program and pass a national certification exam to become licensed.

How did the physician assistant profession begin?

The physician assistant (PA) profession began in the 1960s in the United States as a response to a shortage of primary care physicians, particularly in rural and underserved areas. The first PA program was established at Duke University in 1965, with the goal of training individuals to assist physicians in the delivery of primary care services.

The PA profession was modeled after the medical corpsmen program used by the military during World War II and the Korean War. Corpsmen had received some medical training and were able to assist doctors and surgeons in the field. The idea behind the PA profession was to train similar individuals to work with physicians in civilian settings, to help meet the growing demand for primary care services.

The profession grew rapidly in the 1970s, and by the 1980s, there were over 100 PA programs in the United States. Today, the profession is well established and there are more than 200 accredited PA programs in the country. PAs are licensed to practice in all 50 states, the District of Columbia, and the U.S. territories, and they play a vital role in the healthcare system, particularly in primary care and rural medicine.

What do physician assistants do?

Some of the tasks that PAs may perform include:

  • Taking medical histories and conducting physical exams

  • Ordering and interpreting diagnostic tests, such as X-rays, lab tests, and EKGs

  • Diagnosing and treating illnesses and injuries

  • Prescribing medications

  • Assisting in surgery

  • Providing patient education and counseling

  • Managing chronic conditions such as diabetes and hypertension

  • Assisting in the development and implementation of treatment plans

  • Coordinating care with other healthcare professionals

PAs work closely with physicians, nurses, and other healthcare professionals to provide comprehensive care to patients. They are also involved in research and education, and many are active in professional organizations that advocate for the PA profession.

Is there a need for physician assistants?

Yes, there is a significant need for physician assistants (PAs) in the healthcare system. PAs have licensed healthcare professionals who can provide many of the same services as a physician, and they play a vital role in meeting the growing demand for primary care services.

The United States is currently facing a shortage of primary care physicians, particularly in rural and underserved areas. PAs can help to fill this gap by providing primary care services in these areas, and they can also help to reduce the workload of physicians in other settings.

PAs are also in high demand in specialty fields such as surgery, emergency medicine, and psychiatry. They can provide a cost-effective alternative to physicians in these areas, and they can also help to improve access to care by working in teams with physicians and other healthcare professionals. PAs are also used in non-clinical settings such as research, education, administrative, and management positions.

Overall, PAs are a valuable asset to the healthcare system, and their role is likely to continue to grow in the future as the demand for primary care services continues to increase.
