Allery-Asthma-Anthony

Anthony Huynh, MPAS, PA-C

I am from New Orleans, Louisiana and I graduated from the University of New Orleans in 2017 with a Bachelor’s is Biological Sciences. I spent the next 2 years working as a medical assistant at Urgent Care/Family Medicine. I graduated from the PA program at LSU Health Science Center at Shreveport in 2021. I wanted to become a PA because I was always seeing patients come who felt confused on their symptoms, conditions, and treatments. I wanted to learn more about medicine and be able to treat patients as well as help them have a better understanding of their health.

I wanted to pursue allergy, asthma, and immunology because I feel like these patients cannot fully enjoy their daily lives. Their symptoms will always be lingering around and it’s up to us to help them. Minor changes can cause major improvements.

On my free time, I like to exercise, cook, and write poetry.

FAQs: What is a PA?

  • PA education and practice emphasize patient education, preventive care, and chronic care management. PAs’ generalist medical training enables them to provide a wide spectrum of patient care and treat the “whole patient.” PAs make it easier for patients to get the care they need when they need it.

  • PAs are medical professionals who diagnose illness, develop and manage treatment plans, prescribe medications, and often serve as a patient’s principal healthcare provider. With thousands of hours of medical training, PAs are versatile and collaborative. PAs practice in every state and in every medical setting and specialty, improving healthcare access and quality.

  • PAs are educated at the master’s degree level. There are more than 250 PA programs in the country, and admission is highly competitive, requiring a bachelor’s degree and completion of courses in basic and behavioral sciences as prerequisites. PA programs are approximately 27 months (three academic years) and include classroom instruction and more than 2,000 hours of clinical rotations.

  • A PA’s medical education and training are rigorous. The PA school curriculum is modeled on the medical school curriculum that involves both didactic and clinical education training. In the didactic phase, students take courses in basic medical sciences, behavioral sciences, and behavioral ethics. In the clinical phase, students complete more than 2,000 hours of clinical rotations in medical and surgical disciplines, including family medicine, internal medicine, obstetrics and gynecology, pediatrics, general surgery, emergency medicine, and psychiatry.

  • PAs’ specific duties depend on the setting in which they work, their level of experience, their specialty, and state laws. Generally, PAs can:

    • Take medical histories
    • Conduct physical exams
    • Diagnose and treat illness
    • Order and interpret tests
    • Develop treatment plans
    • Prescribe medication
    • Counsel on preventive care
    • Perform procedures
    • Assist in surgery
    • Make rounds in hospitals and nursing homes
    • Do clinical research
  • There are more than 123,000 PAs who practice in every medical setting in all 50 states and the District of Columbia. They work in hospitals, medical offices, community health centers, nursing homes, retail clinics, educational facilities, workplace clinics, and correctional institutions. PAs also serve in the nation’s uniformed services and work for other federal government agencies, such as the Department of Veterans Affairs.

  • PAs are committed to team practice with physicians and other healthcare providers. Currently, most state laws require PAs to have an agreement with a specific physician in order to

  • Yes. The PA profession is one of the fastest growing in the country. The U.S. Bureau of Labor Statistics projects that the profession will increase 37 percent from 2016 to 2026, significantly faster than the average for all occupations. The demand for PAs is so high that three-quarters of PAs receive multiple job offers upon graduation.

  • PAs are trusted healthcare The survey found that 93 percent regard PAs as trusted healthcare providers, and 91 percent believe that PAs improve the quality of healthcare.

  • At the practice level, there are likely more similarities than differences between PAs and NPs. However, there are two key differences:

    • PAs are educated in general medicine, which offers a comprehensive view of all aspects of medicine. NPs must choose a “population focus,” e.g., pediatric nurse practitioner or women’s health nurse practitioner.
    • PAs are trained to practice medicine using a curriculum modeled on medical school education. NPs are trained in the advanced practice of nursing.
