A nurse anesthetist is not a doctor in the medical sense. Certified Registered Nurse Anesthetists (CRNAs) are advanced practice registered nurses who specialize in administering anesthesia, but they are not physicians. That said, the answer has gotten more nuanced in recent years: as of 2025, all new CRNAs are required to hold doctoral degrees, which means they technically earn the academic title of “Doctor” without being medical doctors.
The Doctoral Degree Requirement
Since January 1, 2025, every graduate of an accredited nurse anesthesia program must hold a doctoral degree, either a Doctor of Nursing Practice (DNP) or a Doctor of Nurse Anesthesia Practice (DNAP). This requirement was phased in over several years: students accepted into programs on or after January 1, 2022, were required to complete a doctorate, and by 2025 the transition became universal.
This is a practice doctorate, not a medical degree (MD) or a research doctorate (PhD). It reflects advanced clinical training in nursing and anesthesia, but the educational path is entirely different from that of a physician. Many CRNAs who graduated before this mandate hold master’s degrees and continue to practice under the same license and certification.
Why “Doctor” Can Be Misleading
Holding a doctoral degree raises a practical question: can a CRNA introduce themselves as “Doctor” to patients? Legally, the answer is increasingly no. In 2025, a U.S. District Court in California ruled that nurses with doctorate degrees do not have the right to call themselves doctors in healthcare settings. The court found that using “Dr.” in clinical contexts is inherently misleading commercial speech, because patients are likely to assume the person is a licensed physician or surgeon. That ruling is not binding nationwide, but it reflects a growing legal and regulatory trend toward restricting the title in clinical environments to avoid patient confusion.
Outside a hospital or clinic, someone with a DNP can accurately say they hold a doctoral degree. In a classroom, in academic writing, or in non-clinical contexts, the “Dr.” title applies the same way it would for anyone with a doctorate in any field. The restriction is specifically about patient-facing healthcare settings where confusion could affect care decisions.
How CRNA Training Differs From an Anesthesiologist’s
The gap between a CRNA and a physician anesthesiologist is most visible in the amount of clinical training. A CRNA completes roughly 2,500 hours of hands-on clinical anesthesia care during their program. An anesthesiologist, who first earns a medical degree and then completes a four-year residency, accumulates 12,000 to 16,000 patient care hours. That’s five to seven times more direct clinical experience before independent practice.
The paths also differ at every stage. To become a CRNA, you first earn a bachelor’s degree in nursing, work as a registered nurse (typically in an intensive care unit for at least one year), then complete a nurse anesthesia program lasting three to four years. An anesthesiologist completes a four-year undergraduate degree, four years of medical school, and four years of anesthesiology residency, often followed by additional fellowship training. Both providers administer the same types of anesthesia, but their foundational education in pharmacology, physiology, and surgical medicine differs significantly in depth and breadth.
What CRNAs Actually Do
CRNAs provide every type of anesthesia: general anesthesia for surgery, regional blocks like epidurals during labor, sedation for procedures, and pain management. They evaluate patients before surgery, develop anesthesia plans, monitor patients throughout procedures, and manage recovery from anesthesia. In practice, much of their day-to-day clinical work looks similar to what an anesthesiologist does in the operating room.
Where they work varies. In larger hospitals and academic medical centers, CRNAs often work alongside physician anesthesiologists in a team-based model, where the physician supervises or collaborates on cases. In smaller community hospitals and rural areas, CRNAs frequently serve as the sole anesthesia providers. As of 2024, governors in 25 states have opted out of the federal requirement that nurse anesthetists be supervised by a physician. In those states, which include California, Iowa, Kansas, Colorado, and Massachusetts among others, CRNAs can practice independently without physician oversight.
Certification and Ongoing Requirements
After completing their degree, CRNAs must pass a national certification exam administered by the National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA). This earns them the CRNA credential. To maintain it, they renew every four years through a Continued Professional Certification program that requires 100 credits of continuing education, split between core knowledge and professional development. At the midpoint of each four-year cycle, they verify their state license and confirm they are actively practicing.
Salary and Career Outlook
CRNAs are among the highest-paid nursing professionals. The median annual salary was $212,650 as of May 2023, according to the Bureau of Labor Statistics. Compensation varies by state, practice setting, and whether the CRNA works independently or in a supervised model. Those practicing in rural or underserved areas, where they may be the only anesthesia provider, sometimes command higher pay due to demand.
The profession continues to grow as healthcare systems look for ways to expand access to anesthesia services, particularly in areas with physician shortages. The shift to mandatory doctoral education has raised the academic floor for new graduates, though it has not changed the scope of practice or the fundamental distinction: a CRNA is a highly trained nurse, not a physician.
