MD vs PA vs NP: What are the Differences Between a Doctor, a Physician Assistant, and a Nurse Practitioner?

When it comes to healthcare, many types of medical professionals work together to provide patients with the best possible care. Each role is integral to the healthcare system, from doctors to nurses to physician assistants and nurse practitioners. However, it can be unclear to understand the differences between these roles and what they each bring to the table.

This article will explore the unique qualifications, roles, and responsibilities of doctors, physician assistants, nurse practitioners, and nurses so you can better understand your healthcare team and the care you receive.

Doctors: An In-Depth Profile (MD)

Education, Training, & Job Responsibilities

A doctor is a medical professional who has completed the most education and training to be licensed to practice medicine. Doctors can specialize in many areas of medicine, including surgery, pediatrics, or psychiatry.

Doctors must complete a four-year undergraduate degree before entering four years of medical school; this typically takes eight years. Medical school is highly competitive, so it's common for students to take several years to apply before matriculating.

After completing their first year at medical school, students spend their summers working with doctors or volunteering at hospitals to gain hands-on experience in their chosen field.

After four years of studying science courses and classes on ethics, communication skills, and leadership (among others), students graduate from medical school ready to take on patients under supervision from more experienced physicians called attendings.

From this, medical students match into advanced residency training. The length will depend on the specialty. For example, family and emergency medicine are three years of supervised training, while surgery can take anywhere from six to nine years.

After residency, a physician can take a lengthy exam and become board-certified. As such, you can practice medicine completely unsupervised, lead the team, and treat highly complicated cases.

Average Salary Details

Physicians can gross anywhere between $200,000 - $400,000+ annually. However, this is highly dependent on their contractual agreements. For example, loan forgiveness and retirement options could be highly beneficial but would decrease their paid salary.

Physician Assistants: An Integral Part of the Healthcare System (PA)

Education and Training

To become a Physician Assistant (PA), the first step is to earn a bachelor's degree, preferably with a focus on healthcare or science-related courses. Once the undergraduate degree is complete, candidates must then apply to an accredited Physician Assistant program, which typically lasts 2-3 years and results in a master's degree.

PA programs are a blend of classroom learning and clinical rotations, covering subjects such as anatomy, pharmacology, medical ethics, and clinical medicine. Upon completion of the program, aspiring PAs must pass the Physician Assistant National Certifying Exam (PANCE) to obtain their certification.

Finally, to start practicing, candidates must apply for a state-specific license and meet any additional local requirements.

Job Responsibilities & Major Roles

PAs work in many different settings, including hospitals and clinics. PAs are educated and trained to help patients with routine medical care, such as physical exams, diagnosing illnesses, ordering tests and procedures, and writing prescriptions.

They do not spend as many years studying as physicians, and the training is less rigorous. This is a great career option for someone who would like to diagnose and treat patients but does not want to undergo as many years of training as a physician.

PAs can perform a few unique procedures but cannot perform independent surgery. In some states, they can practice independently as part of PA-Cs (physician assistants-certified). Many of these positions still require some level of experience and oversight.

Average Salary Details

Physician Assistants gross between $99,000 - $130,000 annually. Per U.S. News, the PA field is expected to grow by 28% between now and 2031. The highest-paid PAs have been noted to make as much as $160,000 a year in California and Florida.

Nurse Practitioners: Providing Comprehensive Patient Care (NP)

Education and Training

Becoming a nurse starts with earning a high school diploma, ideally focusing on math, science, and health subjects. Prospective nurses then need to enroll in an accredited nursing program, which could be an Associate Degree in Nursing (ADN), typically a two-year course, or a Bachelor of Science in Nursing (BSN), usually a four-year degree.

These programs involve prerequisite courses such as anatomy, physiology, and psychology and entail clinical practice hours for hands-on experience in real-world healthcare settings. Post-completion of the program, nurses must pass the National Council Licensure Examination for Registered Nurses (NCLEX-RN), which evaluates the knowledge and skills necessary to practice safely and efficiently at the entry-level.

With a successful pass, candidates can obtain their nursing license and start their career in healthcare. After achieving their Registered Nurse (RN) status, aspiring Nurse Practitioners (NPs) need to pursue advanced education, typically a Master's degree or a Doctorate in Nursing Practice (DNP), from an accredited NP program. These programs often require at least two years of professional nursing experience and involve a blend of classroom learning and clinical training.

Job Responsibilities & Decision-making Autonomy

A Nurse Practitioner (NP) is an advanced practice registered nurse who plays a critical role in healthcare delivery. NPs often provide primary and specialty healthcare, similar to physicians, carrying out tasks such as diagnosing and treating acute and chronic conditions, interpreting lab results, prescribing medications, and providing health education to patients.

NPs often focus on preventative care and wellness. When it comes to decision-making, they have a high degree of autonomy, and in many states, they can operate independently without the supervision of a doctor. As a part of their holistic care approach, NPs consider patients’ physical, psychological, and social well-being while making decisions.

Average Salary Details

According to the U.S. Bureau of Labor Statistics, the average salary for an NP is about $126,000 per year. This is expected to increase with the shortage of healthcare workers.

PA vs NP: Key Differences Between Physician Assistants and Nurse Practitioners

Is a Nurse Practitioner as Good as Seeing a Doctor?

Nurse Practitioners (NPs) are highly trained healthcare professionals who can deliver many services that traditionally fall under a doctor's purview, such as diagnosing conditions, prescribing treatments, and managing patient care. They generally use a patient-centered approach, emphasizing health promotion, disease prevention, health education, and counseling.

From the perspective of routine checkups, minor illnesses, and patient education, an NP is well-equipped to manage these responsibilities proficiently. Nevertheless, doctors, with their extensive training and education, are often preferred for more complex conditions, specialized care, or rare diseases due to their comprehensive understanding of medical science and in-depth expertise in specific areas.

When Is It Better To Visit a Nurse Practitioner Versus a Doctor?

Choosing between an NP and a doctor ultimately depends on patient needs. For routine checkups, minor acute conditions, management of chronic diseases, health counseling, or wellness education, a visit to an NP might be a preferred choice.

NPs, with their patient-centered approach, tend to spend more time with patients, providing education and promoting preventive healthcare practices. Conversely, a doctor's deep specialization and broader medical knowledge may be the better bet for complex medical issues, specialized care, major surgeries, or management of less common diseases.

Is a Doctorate in Nursing the Same as a Nurse Practitioner?

A Doctorate in Nursing Practice (DNP) and a Nurse Practitioner (NP) aren't the same, though they are related. A DNP is a degree, the highest level of academic training in nursing. An NP, on the other hand, is an advanced practice registered nurse who provides patient care. However, nurses often pursue advanced degrees, including a DNP, to become an NP. So, an NP could hold a DNP, but they could also be certified with a master's degree depending on their education and the requirements of the state in which they practice.

Why Consider Becoming a Physician Assistant or Nurse Practitioner?

Career Prospects

As the demand for healthcare services rises, PAs and NPs are increasingly valued for their expertise and wide-ranging skills in the industry. Both professional roles have excellent employment prospects, with the Bureau of Labor Statistics projecting a 27% growth in PA jobs and a 38% growth in NP jobs between 2019 and 2029.

Areas of Specialization

PAs and NPs can specialize in various healthcare and clinical practice areas, enabling them to cater to specific interests. For PAs, specializations may include family practice, emergency medicine, pediatrics, surgery, and orthopedics. At the same time, NPs can specialize in family medicine, acute care, geriatrics, oncology, pediatrics, or psychiatry, to name a few.

Average Salary Details

Both PAs and NPs are compensated quite well for their work. According to the Bureau of Labor Statistics, the median annual wage for PAs was $125,270 in 2022, and for NPs, it was $124,680 in 2022. These competitive salaries, as well as the opportunity to make a positive impact on patients' lives, make these roles even more appealing career options.


In conclusion, while the roles of physicians, physician assistants, and nurse practitioners often overlap within the healthcare system, each distinct profession carries a unique set of qualifications, roles, and responsibilities, as well as differing levels of patient interaction and autonomy.

Physicians undergo the most extensive education and training, allowing them to handle incredibly complex cases and lead medical teams. On the other hand, physician assistants and nurse practitioners serve crucial roles in patient care, from conducting physical exams and diagnosing illnesses to ordering tests and prescribing medications.

They provide a more accessible and often patient-centric form of care, showcasing the healthcare sector's evolution in response to growing patient needs. Understanding these distinctions is critical, not just for aspirants looking to enter the field but for patients navigating their options within a complex healthcare system.
