EMT's: Your Complete Guide to Starting a Rewarding Emergency Medical Career
17 Mar, 2024
If you're exploring a career in medicine or simply trying to understand the healthcare landscape, you've likely come across the term allopathic physicians. These are the doctors most people think of when they picture a physician — professionals who hold a Doctor of Medicine (MD) degree and practice evidence-based medicine. But the healthcare field is vast, and understanding how allopathic physicians fit alongside roles like physician associates and perfusionists can help you make smarter career decisions. I've spent years helping healthcare professionals navigate their career paths through healthcareers.app, and I know firsthand how confusing the medical title landscape can be. In this comprehensive guide, I'll break down everything you need to know about allopathic physicians, how they differ from other practitioners, and what the career outlook looks like in 2024 and beyond.
Allopathic physicians are medical doctors who have earned their Doctor of Medicine (MD) degree from an accredited allopathic medical school. The term "allopathic" comes from the Greek words allos (other) and pathos (suffering), referring to the practice of treating disease with remedies that produce effects different from those caused by the disease itself. In practical terms, allopathic medicine is what most people consider "conventional" or "Western" medicine.
These physicians undergo rigorous training that typically includes:
According to the Association of American Medical Colleges (AAMC), there are currently 157 accredited allopathic medical schools in the United States and Canada. These institutions graduated over 23,000 new MDs in the 2022–2023 academic year alone, underscoring the continued demand for allopathic physicians across virtually every medical specialty.
One of the most common questions I encounter on healthcareers.app is the difference between allopathic physicians (MDs) and osteopathic physicians (DOs). While both are fully licensed physicians who can prescribe medication, perform surgery, and practice in all medical specialties, there are some foundational differences worth understanding.
Allopathic physicians attend MD-granting medical schools, while osteopathic physicians attend DO-granting colleges of osteopathic medicine. Osteopathic training includes everything found in allopathic programs plus an additional emphasis on the musculoskeletal system and osteopathic manipulative treatment (OMT). However, in day-to-day clinical practice, the two types of physicians often function interchangeably.
Both MDs and DOs must pass licensing examinations — the USMLE for allopathic physicians and the COMLEX-USA for osteopathic physicians (though many DOs also take the USMLE). Both can practice in any state, enter any specialty, and work in the same hospitals and clinics. From a patient perspective, the care you receive from an MD and a DO is essentially equivalent.
According to the Bureau of Labor Statistics, employment of physicians and surgeons overall is projected to grow 3 percent from 2022 to 2032, which represents roughly 24,200 openings each year. This growth applies to both allopathic and osteopathic physicians, though the demand is especially strong in primary care, psychiatry, and rural medicine.
Another role that often comes up in career conversations is the physician associate — a title that many people still know by its former name, "physician assistant" (PA). The American Academy of Physician Associates officially adopted the updated title in 2021, and it's been gaining traction ever since. I've seen a surge of interest in this role on our platform, and for good reason.
A physician associate is a licensed medical professional who practices medicine under the supervision (or in collaboration with) a physician. Their scope of practice includes:
Physician associates typically complete a master's-level PA program lasting about 26 to 28 months. While their training is shorter and less specialized than that of allopathic physicians, PAs are trained in the same medical model and work closely alongside MDs and DOs in virtually every clinical setting.
The key differences lie in the depth and duration of training, scope of independent practice, and ultimate clinical authority. Allopathic physicians complete a minimum of 11 years of post-secondary education and training (four years undergraduate, four years medical school, and at least three years of residency), while physician associates complete approximately six to seven years (four years undergraduate plus two to three years of PA school).
In terms of practice, a physician associate typically works as part of a physician-led team. However, legislation in several states is expanding PA autonomy, allowing some to practice with reduced physician oversight. This evolving dynamic makes the physician associate role an attractive option for those who want to practice clinical medicine with a shorter training timeline.
According to the Bureau of Labor Statistics, physician associates earned a median annual wage of $130,020 in 2023, and employment in the field is projected to grow 28 percent from 2022 to 2032 — much faster than average. This makes it one of the fastest-growing roles we track on healthcareers.app.
I get this question more often than you might expect: is a perfusionist a doctor? The short answer is no — a perfusionist is not a physician. But that doesn't diminish the critical importance of this role. Let me explain.
A cardiovascular perfusionist (also called a clinical perfusionist) is a highly specialized healthcare professional who operates the heart-lung machine during cardiac surgery. When a surgeon needs to stop the heart to perform a procedure — such as coronary artery bypass grafting or heart valve replacement — the perfusionist takes over the vital functions of the heart and lungs using extracorporeal circulation technology.
This role requires extraordinary precision, calm under pressure, and deep knowledge of cardiovascular physiology. Perfusionists also manage:
Most perfusionists hold a bachelor's or master's degree in perfusion science or a related field. Programs accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) typically require two to four years of study beyond a bachelor's degree. After completing their education, perfusionists earn certification through the American Board of Cardiovascular Perfusion (ABCP).
So while a perfusionist is not a doctor, they are an essential member of the cardiac surgery team who works directly alongside allopathic physicians — specifically cardiothoracic surgeons and cardiac anesthesiologists. The National Institutes of Health has published research highlighting the critical role perfusionists play in patient outcomes during cardiac procedures, reinforcing the importance of this allied health profession.
Perfusionists are well-compensated for their specialized skills. While the Bureau of Labor Statistics groups them under broader categories, industry data suggests that certified perfusionists earn between $90,000 and $150,000 annually, depending on experience, location, and employer. With an aging population and increasing rates of cardiovascular disease, demand for skilled perfusionists remains strong.
We built healthcareers.app because we believe every healthcare professional deserves clarity when making career decisions. Here's a quick comparison to help you evaluate these three paths:
Each of these roles fills a vital need in our healthcare system. The right choice depends on your interests, your appetite for training, your financial situation, and the kind of patient interaction you find most fulfilling.
One trend I've observed through our work on healthcareers.app is the increasing emphasis on team-based care. Allopathic physicians are no longer solo practitioners working in isolation. Today's medical teams include physician associates, nurse practitioners, perfusionists, pharmacists, respiratory therapists, and dozens of other specialized professionals, all collaborating to deliver the best possible patient outcomes.
This evolution has made it more important than ever for aspiring healthcare professionals to understand not just their own role, but how they fit into the broader care team. Whether you're an allopathic physician leading a surgical team or a physician associate managing a panel of primary care patients, your ability to collaborate effectively is just as important as your clinical knowledge.
The healthcare workforce is also facing significant shortages. The AAMC projects a shortfall of between 37,800 and 124,000 physicians by 2034, with primary care and rural specialties hit hardest. This means that opportunities for allopathic physicians — and for the allied health professionals who support them — will continue to expand for the foreseeable future.
Allopathic physicians hold an MD (Doctor of Medicine) degree, while osteopathic physicians hold a DO (Doctor of Osteopathic Medicine) degree. Both are fully licensed to practice medicine, prescribe medications, and perform surgery. The primary difference is that osteopathic training includes additional coursework in osteopathic manipulative treatment and a more holistic philosophical approach. In clinical practice, both provide equivalent care.
Yes. "Physician associate" is the updated title for the role formerly known as "physician assistant." The American Academy of Physician Associates adopted the new title in 2021 to better reflect the collaborative nature of the role. The credentials, scope of practice, and training remain the same regardless of which title is used.
No, a perfusionist is not a doctor. Perfusionists are allied health professionals who specialize in operating heart-lung machines during cardiac surgery. They hold bachelor's or master's degrees in perfusion science and are certified by the American Board of Cardiovascular Perfusion. While they are not physicians, they work directly alongside allopathic physicians in the operating room and are essential to cardiac surgical outcomes.
Becoming an allopathic physician typically takes a minimum of 11 years after high school: four years of undergraduate education, four years of medical school to earn the MD degree, and at least three years of residency training. Those pursuing subspecialties may complete an additional one to three years of fellowship, bringing the total to 12–15 years or more.
Some of the highest-paying specialties for allopathic physicians include neurosurgery, orthopedic surgery, cardiology, gastroenterology, and plastic surgery. According to physician compensation surveys, these specialties can command median annual salaries ranging from $400,000 to over $700,000. However, compensation varies significantly by geographic location, practice setting, and experience level.
Understanding the role of allopathic physicians — and how they relate to physician associates, perfusionists, and other healthcare professionals — is essential for anyone considering a career in medicine. Whether you're drawn to the comprehensive training and full clinical authority of an MD, the collaborative and fast-growing physician associate role, or the high-stakes precision of perfusion science, there's a path that matches your passion and goals.
