Why Get a Doctorate in Nursing: DNP Benefits & Careers

You have built a career on clinical judgment, advocacy, and care that patients remember. Now you are asking what comes next. For many nurses, the answer is a doctoral degree.

A Doctor of Nursing Practice (DNP) degree can set you on a new path. That path leads to advanced clinical practice, leadership, and healthcare innovation. Demand for highly educated nursing professionals keeps rising. Health systems need nurses who deliver evidence-based, patient-centered care and lead change in policy and practice.

This guide answers the question so many nurses ask: why get a doctorate in nursing? You will learn what the degree is, what graduates do, and how long it takes. You will also see how the two DNP tracks at Mass General Brigham University work.

What Is a Doctor of Nursing Practice?

The Doctor of Nursing Practice is a terminal professional degree in nursing. It focuses on the clinical side of nursing leadership rather than academic research. In short, it prepares you for the highest level of nursing practice.

A DNP builds on your nursing degree and your years at the bedside. Coursework covers evidence-based practice, healthcare policy, quality improvement, informatics, and systems leadership. Most programs end with a scholarly project that solves a real problem in care delivery.

Doctor Nursing Degrees: DNP or PhD?

Nursing offers two doctoral degrees, and they serve different goals. PhD graduates create new knowledge through nursing research. They often work as nurse scientists in universities, research centers, and academic health systems.

DNP graduates translate that knowledge into practice. They apply evidence at the bedside, in clinics, and across entire health systems. Both degrees advance nursing science. They simply approach it from different directions.

Some nurses eventually earn both. Rachel Cox Simms, PhD, DNP, RN, FNP-BC, teaches at Mass General Brigham University and holds each degree.

Why Get a Doctorate in Nursing? Five Reasons

Every nurse has a personal reason for returning to school. These five come up most often in our admissions conversations.

1. Advanced Clinical Skills

A DNP sharpens your ability to appraise evidence and act on it. You learn to evaluate outcomes for individual patients and whole populations. That skill set raises the quality and safety of the care you give.

2. Leadership Across Healthcare Systems

The degree prepares you for leadership in hospitals, health systems, clinics, and academic institutions. You gain fluency in finance, informatics, and organizational change. Strong nursing leadership is closely linked to staff satisfaction and retention.

3. Influence on Health Policy

DNP-prepared nurses advocate for the profession and for patients at the highest levels. They sit on hospital boards, advise agencies, and testify on regulation. Policy work is where scope-of-practice barriers finally shift.

4. Contribution to Nursing Science

The DNP applies nursing research to practice settings to improve care quality and safety. You learn to design, implement, and measure real improvement projects. Your findings can then inform practice far beyond your own unit.

5. Career Advancement

Many senior clinical and executive roles now list a doctorate as preferred or required. A DNP positions you for those postings before they open. It also supports long-term career advancement into roles you may not have considered yet.

What Does a Doctor of Nursing Practice Do?

So, what does a Doctor of Nursing Practice do day to day? The answer depends on the path you choose. Here are six common directions for DNP graduates.

• Nurse practitioner: Diagnoses and treats patients, often with a high degree of autonomy.
• Nurse executive: Leads nursing organizations, sets strategy, and drives systemic quality improvement.
• Nurse educator: Teaches and mentors the next generation of nursing students and clinicians.
• Nurse anesthetist: Delivers anesthesia and pain management with advanced training and leadership skills.
• Nurse midwife: Provides maternal care and leads women's health initiatives and advocacy.
• Nurse scientist or quality leader: Turns evidence into new protocols, workflows, and standards of care.

Many DNP graduates blend several of these roles. A nurse executive may also teach. A nurse practitioner may also lead a quality improvement team.

Doctor of Nursing Practice vs. Nurse Practitioner

Nurses often use these two terms as if they mean the same thing. They do not. One is a degree, and the other is a role. 

An NP is a role, not a degree. Nurses reach it through an MSN or doctoral program, then national certification. A DNP is a degree that NPs and other advanced practice registered nurses (APRNs) may choose to pursue. It represents a further step focused on practice, leadership, and translating research.

How Long Does It Take to Earn a DNP?

Program length depends on the degree you already hold. Enrollment status and specialization also affect your timeline.

• Bachelor of Science in Nursing (BSN) to DNP: three to four years of doctoral study.
• MSN to DNP: one to two years, since graduate coursework is already complete.
• Non-nursing master's degree: eligible at MGBU, though prerequisites may be required.

Part-time study extends these ranges. Full-time study shortens them. Ask an admissions counselor to map a realistic schedule around your clinical hours.

The Impact of DNP Graduates on Healthcare

Healthcare is growing more complex every year. Aging populations, chronic disease, and workforce shortages strain every system. Nurses with doctoral preparation are positioned to respond.

DNP-prepared nurses redesign workflows, close gaps in access, and reduce preventable harm. They bring frontline insight into rooms where budgets and policies are set. That combination of clinical credibility and systems thinking is rare and valuable.
