A person who holds a Doctor of Nursing Practice (DNP) degree has earned a legitimate doctoral degree and can accurately be called “doctor” in an academic sense. But they are not a medical doctor, and whether they can use the title in a clinical setting depends on the state where they practice. The distinction matters more than it might seem, because research shows that most patients cannot tell the difference between a physician and a non-physician based on titles alone.
What the DNP Degree Actually Is
The Doctor of Nursing Practice is a doctoral-level degree designed for nurses who want to reach the highest level of clinical nursing practice. The American Association of Colleges of Nursing (AACN) voted in 2004 to make the DNP the standard credential for advanced practice nurses, including nurse practitioners, nurse anesthetists, clinical nurse specialists, and nurse midwives. The reasoning was twofold: the credit load for master’s-level nursing programs had already grown to match doctoral programs in other fields, and a doctorate would put nursing on par with pharmacy, physical therapy, and other health professions that require a doctoral degree for advanced practice.
DNP coursework centers on evidence-based practice, quality improvement, leadership, health policy, and systems thinking. It is a practice-focused degree, not a research degree (that would be a PhD in nursing). The goal is to prepare expert clinicians and leaders who can improve patient outcomes and healthcare delivery, not to train researchers or physicians.
How “Doctor” Applies to Both, and Neither
The word “doctor” comes from the Latin verb “docere,” meaning to teach. It was originally a title for eminent scholars in the Middle Ages, long before it had any connection to medicine. The PhD, or Doctor of Philosophy, remains the highest graduate degree awarded by universities and is the oldest use of the title.
Medical schools began calling their graduates “doctor” in the 17th century, particularly in Scotland, borrowing the prestige of the academic title. But an MD is technically a professional degree, not a graduate research doctorate. It is not awarded through the graduate faculty at most North American universities. So in the strictest academic sense, a DNP holder and a PhD holder have a stronger claim to the title “doctor” than a physician does. In practice, of course, the public associates “doctor” almost exclusively with physicians, and that everyday meaning is what creates confusion.
The Training Gap Between DNPs and MDs
While both degrees are doctoral-level, the clinical training behind them is vastly different. A post-master’s DNP program may require around 450 clinical hours of residency experience. A physician completes four years of medical school followed by three to seven years of residency, accumulating somewhere between 12,000 and 16,000 hours of supervised clinical training before practicing independently. That difference is not a small gap. It represents fundamentally different depths of preparation for diagnosing and treating disease.
The curriculum focus also diverges sharply. Medical education is built around pathology, pharmacology, anatomy, and the diagnosis and treatment of specific conditions. DNP education emphasizes whole-person health, disease prevention, health promotion, and nursing leadership. Both approaches have value, but they prepare professionals for different roles. A DNP-prepared nurse practitioner and a physician are not interchangeable, even when they work in similar clinical settings.
Whether DNPs Can Use “Doctor” With Patients
This is where things get legally complicated, and the answer changes depending on where you live. Some states restrict the use of “doctor” or “Dr.” in clinical settings to licensed physicians. California’s Business and Professions Code, Section 2054, has prohibited non-physicians from using “doctor” in medical contexts since at least 1937. In 2023, a federal court upheld that law after three nurse practitioners with DNP degrees challenged it as unconstitutional. U.S. District Judge Jesus G. Bernal treated the use of the title as commercial speech and ruled that the restriction serves California’s interest in protecting patients from misleading advertising. That ruling is currently being appealed to the 9th Circuit Court of Appeals.
Other states take a more permissive approach. Minnesota, for example, does not prohibit an advanced practice registered nurse (APRN) with a doctoral degree from using the title “doctor.” However, the state suggests that nurses who do so also identify themselves as nurses. The general principle across most states is the same: if you use a doctoral title in a healthcare setting, you need to make your actual role clear to patients.
Why the Title Distinction Matters to Patients
A California survey found that only 9% of participants could correctly match a healthcare practitioner’s level of training with their title. When presented with credential abbreviations, 91% of participants failed to distinguish a physician from a non-physician. Among those surveyed, 19% believed that a “Doctor of Nursing Practice” was definitely a physician, compared to 76% who correctly identified “Medical Doctor” as a physician.
The study also revealed something telling about the power of words: when the title “Nurse Practitioner” was changed to “Doctor of Nursing Practice,” the percentage of people who could correctly identify that person as a non-physician dropped from 33% to 19%. Simply adding the word “doctor” to a healthcare title made patients significantly more likely to assume they were seeing a physician. The federal judge in the California case cited similar survey data showing that 39% of patients wrongly believed a DNP holder was a physician.
This confusion is not abstract. When patients assume their provider has physician-level training, they make different decisions about their care. They may not seek a second opinion, may not ask about their provider’s qualifications, and may not understand the scope of what their provider is trained to do.
What DNPs Can and Cannot Do
Nurse practitioners, including those with DNP degrees, can diagnose conditions, prescribe medications, and manage patient care. In about half of U.S. states, they can do so independently without physician oversight. Their scope of practice is governed by state nursing boards, not medical boards, and varies considerably by state.
One notable difference from physician training: a nurse practitioner certified in primary care can practice in specialties like cardiology, dermatology, or neurology without completing additional formal education or training in those areas. Physicians, by contrast, must complete a residency in their chosen specialty and often pursue additional fellowship training. This structural difference in how specialization works is one of the key clinical distinctions between the two professions, regardless of what title either one uses.
DNPs do not perform surgery, and their prescriptive authority, while broad, is more limited than a physician’s in some states. Their training prepares them to focus on health promotion, disease prevention, and coordinated care rather than the full diagnostic and procedural scope of a physician.
The Short Answer
A Doctor of Nursing Practice holds a real doctorate and has earned the academic right to be called “doctor.” They are not a medical doctor, and in some states, they are legally barred from using the title in clinical settings because it misleads patients. The degree represents advanced nursing expertise, not medical training, and the two involve very different amounts of clinical preparation. If your healthcare provider introduces themselves as “doctor,” it is reasonable to ask whether they are a physician, a nurse practitioner, or another type of doctoral-level professional.
