Physician Assistant
Last updated
Physician Assistants (now also called Physician Associates in some contexts) are advanced practice providers who examine patients, diagnose illness, prescribe medications, and perform procedures under physician supervision or collaborative practice agreements. They practice across primary care, emergency medicine, surgery, and virtually every specialty, providing care that is clinically equivalent to physician care for a broad range of conditions.

Overview
Physician Assistants provide medical care that spans the full clinical scope of their practice setting — taking histories, examining patients, making diagnoses, prescribing treatments, and performing procedures. In primary care, a PA running their own patient panel of 1,500 adults with chronic conditions is managing most of those patients' healthcare needs independently, consulting the supervising physician on complex cases. In orthopedic surgery, a PA is first-assisting in the OR on two to four cases per day, rounding on post-operative patients in the morning, and seeing clinic appointments in the afternoon.
The PA role's defining feature is its generalist foundation. PA training covers all of medicine — internal medicine, surgery, pediatrics, OB/GYN, psychiatry, emergency medicine — before a PA enters any specialty. This breadth creates flexibility that physicians rarely have: a PA who trained in emergency medicine can transition to a hospital medicine role with a focused orientation period, or move from family practice to cardiology. The clinical skills transfer; the specialty knowledge requires dedicated learning.
The inpatient side of PA practice has grown significantly. Hospitalist PA positions — managing inpatient medicine admissions and discharges under physician supervision — are common at most health systems. Surgical service PAs manage the floor patients of busy surgical attendings who are otherwise in the operating room for most of the day. Intensive care PAs provide round-the-clock coverage on medical and surgical ICUs.
Documentation and administrative burden affect PAs as much as physicians. Prior authorization requests, quality metric documentation, note completion requirements, and EHR demands consume a significant share of clinical time. PAs who are efficient in the EHR — templating appropriately, dictating versus typing, using clinical decision support rather than fighting it — consistently report better work satisfaction than those who fall behind on documentation.

Career outlook
Physician Assistant employment is projected to grow 28% over the next decade — among the fastest of any healthcare profession — according to BLS projections. The drivers are structural: physician shortages in primary care and many specialties, health system economics that favor APP staffing for appropriate patient care, and expanding state scope-of-practice laws that allow PAs to practice more independently.
The geographic demand picture strongly favors PAs willing to work in shortage areas. Rural communities, FQHCs, Indian Health Service sites, and small-city markets have PA vacancies that remain unfilled for extended periods. NHSC loan repayment programs for PAs working in underserved settings can eliminate $50K–$100K+ in educational debt over a service period, substantially improving the net compensation picture for new graduates.
Surgical PA positions are among the most stable and highest-compensated. Surgical specialties that grew their PA utilization as a way to increase OR efficiency have embedded these roles deeply; the PA in the OR is no longer optional in many high-volume orthopedic, spine, and cardiac surgery programs. These positions are hard to break into without specialty experience but very stable once established.
The nurse practitioner versus PA workforce debate will continue. States are expanding NP independent practice at a faster pace than PA independent practice, and NP training programs have grown more rapidly than PA programs. In the near term, this creates competition for the same patient care roles in some settings. The clinical outcome evidence does not differentiate between PAs and NPs for most conditions, and health systems generally use the two interchangeably for primary care and many specialty roles.
For people who want a clinical career with physician-level scope, substantial autonomy, and more career flexibility than the full physician training path allows, the PA profession offers a compelling combination. Entering PA school with clear specialty direction — and pursuing relevant experience before and during school — positions new graduates to move into competitive specialty roles rather than defaulting to positions that don't match their clinical interests.
Sample cover letter
Dear Hiring Manager,
I'm applying for the Physician Assistant position in your Orthopedic Surgery department at [Medical Center]. I graduated from [PA Program] last spring, passed the PANCE in September, and have been working at [Orthopedic Practice] as a new graduate PA in a mixed clinic and post-operative coverage role.
In my current position, I see 15–18 clinic patients per day — new consultations and post-operative follow-up — and provide first-assist coverage for three to four OR cases per week across total joint arthroplasty and outpatient arthroscopy. I've assisted on approximately 90 OR cases since starting, including primary total hip and knee cases and one revision hip.
I chose orthopedics during PA school because my final rotation was at an orthopedic surgery practice and I found the combination of the outpatient diagnostic work and the OR environment genuinely engaging. I've continued building toward that specialty deliberately. My weakest area right now is complex trauma — I haven't had much exposure to ORIF and long bone fracture cases, and I know that's a gap I want to fill.
I'm applying to [Medical Center] because of your trauma volume and your reputation for PA development. An environment where I can continue building on a strong basic foundation toward more complex surgical cases is where I want to be for the next phase of my career.
I'm available to discuss the position at your convenience.
Thank you, [Your Name], PA-C
Frequently asked questions
- What is the difference between a PA and a nurse practitioner?
- Both are advanced practice providers who can diagnose, prescribe, and treat independently (in most states). PAs have a medical model education — trained across all specialties in a generalist medical curriculum similar in structure to medical school. NPs have a nursing model education with a specialty focus (family, adult-gerontology, pediatric, psychiatric). In practice, the clinical capabilities are often similar for comparable experience levels, though PAs have more flexibility to change specialties due to their generalist training.
- What does PA training require?
- Most PA programs are 27 months long and require a bachelor's degree plus healthcare experience (typically 2,000+ hours) for admission. The curriculum includes didactic coursework followed by clinical rotations across medicine, surgery, OB/GYN, psychiatry, emergency medicine, and pediatrics. The PANCE (Physician Assistant National Certifying Examination) is required for initial certification as PA-C. The title 'Physician Associate' has been adopted by some organizations alongside 'Physician Assistant.'
- Can PAs practice independently without a physician?
- Scope of practice varies by state. Most states require some form of collaborative or supervisory relationship with a physician, though the degree of supervision required varies from formal supervision to simple collaborative agreement. A handful of states have moved to independent practice for experienced PAs. The national trend is toward greater PA autonomy, following the pattern established by NP independent practice expansion.
- How easily can a PA switch specialties?
- PA generalist training makes specialty transitions more accessible than for physicians, who invest 3–7 years in specialty residency. PAs transitioning between specialties typically do a fellowship, a formal onboarding and supervised practice period, or lateral movement within a health system. The transition period takes 3–12 months of supervised practice depending on the distance between the old and new specialty. This flexibility is often cited as a major career advantage of the PA path.
- Are PAs in demand for surgical specialties?
- Yes — surgical PAs are among the highest-compensated in the profession. Orthopaedic, neurosurgical, cardiothoracic, and spine surgical teams rely heavily on PAs for first-assist roles in the OR, post-operative rounding, discharge management, and clinic. Surgical PA positions often require experience in the relevant specialty before hire, making them harder to enter directly from PA school but very stable once established.
