This rigorous education ensures PAs are fully prepared for clinical practice.

PAs bring their advanced medical skills to serve patients in every community.

Why are PAs So Important in Healthcare?

There are several key reasons physician assistants have become integral providers:

PAs Increase Access to Care

A predicted doctor shortage combined with millions more Americans gaining insurance means provider supply isn’t meeting demand. As fully licensed medical practitioners, PAs can help fill this gap. Their skills allow them to diagnose, treat, and monitor patients like physicians do. Having PAs provides more appointment availability and expands access.

PAs Lower Healthcare Costs

Utilizing PAs allows healthcare facilities to reduce costs while maintaining high quality care. On average, it costs 20-25% less to employ a PA versus a doctor. PAs also order fewer expensive diagnostic tests and prescribe generic options more frequently. Facilities can serve more patients and accept more insurance plans when PAs offset expenses.

PAs Provide Exceptional Care

Despite less training, research consistently shows PAs perform at the same level as physicians when it comes to quality metrics like prescribing patterns, readmission rates, patient outcomes and satisfaction. They provide complete care and spend more time per patient. The PA model itself fosters excellent communication and coordination within the medical team.

PAs Increase Patient Satisfaction

Surveys demonstrate patients are highly satisfied with the care provided by PAs. Their comprehensive medical knowledge is combined with a warm beside manner focused on listening and educating. Many patients appreciate having a consistent PA overseeing their care. Positive experiences build loyalty and trust.

PAs Serve in Underserved Areas

With expanding autonomy, PAs can help meet needs in rural and urban areas lacking adequate medical providers. Their advanced capabilities allow them to diagnose and treat patients comprehensively without requiring a physician on site full time. PAs also bring healthcare directly to schools, homeless shelters, prisons, and other settings.

The versatility, skills, and cost-effectiveness of PAs make them essential for providing quality comprehensive care and meeting growing access demands.

Benefits of Working with PAs

Using PAs in medicine has many benefits for patients, providers, facilities, and the broader healthcare system:

PA Career Outlook

The PA occupation is one of the fastest growing in healthcare. According to the Bureau of Labor Statistics:

  • PA job growth is projected at 31% between 2020-2030, more than 4 times the national average for other occupations.

  • This translates to an increase of over 40,000 new PA jobs in the next decade.

  • Shortages across medical and surgical specialties are driving massive PA demand.

  • Clinical settings nationwide are actively recruiting PAs through increased salaries and benefits.

Almost all indicators point to a booming job market for certified PAs now and in the future. PA programs graduate around 10,000 new PAs annually – still far below market demand.

For those interested in a career as a medical provider, becoming a PA offers tremendous opportunities for job stability, flexibility, earning potential, and the immense rewards of caring for patients.
