  • What is a physician assistant? 

    A physician assistant (PA) is a medical professional who works as part of a team with a doctor. A PA is a graduate of an accredited PA educational program who is nationally certified and state-licensed to practice medicine with the supervision of a physician.

     

    What can PAs do?  

    PAs perform physical examinations, diagnose and treat illnesses, order and interpret lab tests, perform procedures, assist in surgery, provide patient education and counseling and make rounds in hospitals and nursing homes. All 50 states and the District of Columbia allow PAs to practice and prescribe medications.

     

    How are PAs educated and trained?  

    The PA educational program is modeled on the medical school curriculum, a combination of classroom and clinical instruction. The PA course of study is rigorous and intense. The average length of a PA education program is 27 months.

    Admission to PA school is highly competitive. Applicants to PA programs must complete at least two years of college courses in basic science and behavioral science as prerequisites to PA school, analogous to premedical studies required of medical students. The majority of PA programs have the following prerequisites: chemistry, physiology, anatomy, microbiology and biology. Additionally, most PA programs require or prefer that applicants have prior healthcare experience.

    PA education includes instruction in core sciences: anatomy, physiology, biochemistry, pharmacology, physical diagnosis, pathophysiology, microbiology, clinical laboratory science, behavioral science and medical ethics.

    PAs also complete more than 2,000 hours of clinical rotations, with an emphasis on primary care in ambulatory clinics, physician offices and acute or long-term care facilities. Rotations include family medicine, internal medicine, obstetrics and gynecology, pediatrics, general surgery, emergency medicine and psychiatry.

    Practicing PAs participate in lifelong learning. In order to maintain national certification, a PA must complete 100 hours of continuing medical education every two years.

    There are currently 181 accredited PA programs in the United States. The vast majority award master’s degrees. PA education programs are represented by the Physician Assistant Education Association and accredited through the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA).

     

    How do doctors and PAs work together? If there’s a PA in my practice group, can I request to be seen by the PA? 

    By design, physicians and PAs work together as a team, and all PAs practice medicine with physician supervision. Supervision does not mean, though, that a supervising physician must always be present with the PA or direct every aspect of PA-provided care.

    PAs are trained and educated similarly to physicians, and therefore share similar diagnostic and therapeutic reasoning. Physician-PA practice can be described as delegated autonomy. Physicians delegate duties to PAs, and within those range of duties, PAs use autonomous decision-making for patient care. This team model is an efficient way to provide high-quality medical care. In rural areas, the PA may be the only healthcare provider on-site, collaborating with a physician elsewhere through telecommunication.

    If there is a PA in your group practice, you can certainly request to be seen by him or her. PAs deliver high-quality care, and research shows that patients are just as satisfied with PA-provided care as they are with physician care.
