The old model of one job, one hospital, one career path isn’t holding up well. Burnout, retirements, and a surge in patient demand have pushed the U.S. healthcare system to a breaking point - and the numbers are stark. In 2025, the country faced a shortage of 84,930 physicians, 250,710 registered nurses, and 81,330 LPNs, according to the 2025 Healthcare Staffing Statistics report published by AAG Health.
What’s surprising is that this crisis is also opening doors. Hospitals and clinics that can’t fill permanent roles are turning to flexible staffing models to keep their departments running. PRN shifts, locum tenens contracts, and per diem arrangements are no longer last resorts - they’re becoming a legitimate career strategy for clinicians who want more control over when, where, and how much they work.
If you’re considering a career in healthcare, or you’re already working in the field and wondering whether flexible work is worth exploring, the short answer is yes. The demand is real, the pay is competitive, and the options cover far more specialties than most people expect.
PRN comes from the Latin “pro re nata,” which roughly translates to “as needed.” In practice, it means a clinician picks up shifts at a facility when coverage is required - no fixed schedule, no guaranteed hours, and no single employer. It’s different from locum tenens, which typically involves a multi-week contract assignment at a specific facility, often in a different city or state. Both models give clinicians flexibility; the scale and commitment level differ.
The pay difference is real. PRN nurses typically earn 20-30% more per hour than their full-time counterparts, according to 2025 reporting from Your Health Magazine. That premium reflects the lack of employer-provided benefits and the on-demand nature of the work. For clinicians who already have coverage through a spouse or part-time benefits, the trade-off often makes financial sense.
Platforms built around PRN healthcare staffing connect credentialed clinicians directly to facilities that need coverage - sometimes within hours of a shift opening. That speed would have been impossible to coordinate a decade ago. Technology has made it practical for a nurse to work at three different hospitals in a week, each booking handled through a single app.
The tradeoff is real, though. No guaranteed income, no employer-sponsored retirement plan, and no paid time off. Clinicians who go fully PRN need to be disciplined about building their own financial cushion. That caveat aside, 97% of healthcare organizations planned to expand their use of flexible work options - including per diem, float pools, and contract roles - in 2025, according to the Hallmark HCS Healthcare Staffing Report.
The flexible staffing boom isn’t a trend that appeared out of nowhere. It’s a structural response to a genuine workforce problem that hospitals have been managing for years and can’t solve quickly.
Locum tenens numbers tell part of the story. In 2024, healthcare organizations’ actual locum tenens utilization was 25% higher than they had projected going into the year, according to the CHG Healthcare 2025 State of Locum Tenens Report. Facilities keep underestimating how much flexible physician coverage they’ll need - and they keep being wrong in the same direction.
The macro picture backs this up. The U.S. healthcare staffing market was valued at $45.48 billion in 2025 and is projected to reach $89.71 billion by 2033, according to market data from Vars Health. That’s not a bubble - it’s the financial reflection of a workforce problem that’s going to take a generation to work through.
The American Hospital Association’s 2025 health care workforce report documents the pressure in detail: rising labor costs, accelerating retirement among experienced nurses and physicians, and a pipeline of new graduates that doesn’t come close to matching attrition rates. Hospitals aren’t doing this by choice - they’re doing it because permanent hiring alone can’t fill the gaps.
For job seekers, this context matters. You’re not entering a niche corner of the job market by pursuing flexible healthcare work. You’re stepping into what is increasingly the mainstream way healthcare gets staffed. Workers who understand the difference between PRN and locum tenens, and who’ve built their credentials accordingly, are positioned well.
One of the biggest misconceptions about PRN and locum tenens is that they’re primarily for ER nurses and hospitalist physicians. The reality is that flexible staffing spans nearly every specialty, and some of the highest-paying opportunities are in areas most job seekers don’t think to look.
Psychiatry stands out as an area of particular need: roughly 160 million Americans live in a designated psychiatry shortage area, a figure that hasn’t improved meaningfully in years. Cardiology and oncology are also growing fast - the Bureau of Labor Statistics projects continued job growth for physicians in both fields through 2033, and specialist shortages make flexible coverage especially valuable. A locum cardiologist covering a rural hospital can mean the difference between a patient getting treated locally or driving four hours for care.
CompHealth’s list of the top 12 in-demand locum tenens specialties for 2025 includes emergency medicine, anesthesiology, psychiatry, cardiology, radiology, and surgical subspecialties - a list that should disabuse anyone of the notion that flexible work is limited to general practice or nursing.
The breadth of options is the point. A licensed practical nurse, a radiologist, a physical therapist, and a psychiatrist can all find PRN or locum work that fits their license, their schedule, and their financial goals. You don’t have to be in emergency medicine to benefit from the flexibility trend.
Surgical specialties are among the fastest-growing segments within flexible physician staffing, and plastic and reconstructive surgery is near the top of that list. The global plastic surgery market was projected at $85.98 billion in 2025 and is expected to reach $245.46 billion by 2035 - a compound annual growth rate of 11.06%, according to Towards Healthcare’s 2025 market sizing report. That’s not the kind of growth curve that suggests a softening job market.
Nearly 38 million aesthetic procedures were performed globally in 2024, a 42.5% increase over a four-year period. And on the surgical training side, match numbers for surgical specialties were up over 4% in 2025 compared to 2024, according to the American College of Surgeons. Demand from patients is growing faster than the specialty can produce trained surgeons.
For physicians interested in this field, locum tenens pay for plastic surgery specialists ranges from roughly $677,000 to $764,000 annually based on AMN Healthcare compensation data - figures that reflect both the technical complexity of the work and the shortage of specialists willing to take on temporary placements.
Subspecialties within the field include facial plastic surgery, craniofacial reconstruction, hand surgery, and burn reconstruction. These aren’t interchangeable; each requires specific fellowship training and carries its own credentialing requirements for locum work. Rhinoplasty is among the most technically demanding facial procedures and tends to be concentrated in high-volume urban markets where both elective and reconstructive demand is strong. For clinicians evaluating where to practice or seek locum placements, understanding what excellent surgical practice looks like in specific cities matters - researching the best rhinoplasty Washington DC practices can give a sense of the clinical standards and patient expectations these markets demand.
The reconstructive side of the field - cleft palate repair, post-mastectomy reconstruction, trauma reconstruction - is less prominent than elective work but often more consistent in terms of patient volume and insurance reimbursement. Clinicians who can cover both tend to have more options when evaluating locum placements.
Before committing to a specialty, a staffing model, or a new state license, structured research pays off. Healthcare career decisions are expensive to reverse - fellowship training takes years, state licenses take months, and malpractice tail coverage can run into thousands of dollars when you leave a role.
Start with the Bureau of Labor Statistics Occupational Outlook Handbook, which gives 10-year growth projections and median pay for every major healthcare occupation. Cross-reference that with staffing platform data: most major locum tenens firms publish annual reports on which specialties are in highest demand, and those reports are free to access.
Licensing requirements vary significantly by state, which matters enormously for locum work. Physicians pursuing interstate assignments need to research individual state medical board requirements or consider the Interstate Medical Licensure Compact. Nurses have a somewhat easier path through the Nurse Licensure Compact, which covers 41 states as of 2025.
Salary benchmarking tools and rate calculators from firms like CompHealth, AMN Healthcare, and Locum Leaders are worth using before you accept any contract. The spread between a good locum placement and a mediocre one can be $50-$100 per hour for the same specialty, in the same state, on the same week.
The practical steps for entering the PRN or locum market aren’t complicated, but they do require lead time. Most facilities need at least 30 days of notice for per diem scheduling, and locum placements often require 60-90 days from first contact to first shift.
Start with your credentials. An updated license in good standing is the baseline. Beyond that, you’ll want current certifications relevant to your specialty - BLS, ACLS, PALS as applicable - along with a clean malpractice history and at least two strong professional references. Staffing platforms screen for all of these before placing you, and any gaps will slow the process.
Get your malpractice coverage sorted before accepting work. Some facilities provide coverage for locum physicians; others don’t. PRN nurses are typically covered under the facility’s policy while working a shift, but it’s worth confirming. Many locum clinicians carry their own supplemental coverage regardless.
Choose your platform based on your specialty and preferred work type. Nursa is built for PRN nursing shifts and connects nurses to open shifts quickly. CompHealth and AMN Healthcare focus on locum tenens physician placements with longer-term contracts. Most clinicians end up registered on two or three platforms to keep their options open.
The healthcare staffing crisis has shifted leverage toward clinicians willing to work flexibly. That’s not going to change in the next few years - the demographic math doesn’t support it. Too many experienced nurses and physicians are retiring, too few new graduates are entering the workforce, and patient demand keeps growing.
PRN nursing, locum tenens physician roles, and per diem allied health work aren’t second-tier options. In many cases they pay more per hour than permanent positions, offer genuine schedule control, and let clinicians try different practice settings before committing to one. Surgical subspecialties, including plastic and reconstructive surgery, are part of this growth curve - and they tend to offer the highest pay per hour of any locum specialty.
The work it takes to get credentialed for flexible staffing is real, but it’s finite. A few months of preparation - updated licenses, certifications, references, and platform registration - can open a career path that most clinicians don’t consider until they’ve spent years feeling stuck somewhere that no longer fits.
