What Is Evidence-Based Practice in Nursing?
Evidence-based practice (EBP) is a problem-solving approach to health care that integrates the best research evidence, clinical expertise, and patient preferences. It focuses on providing holistic care based on the most recent and documented scientific knowledge rather than relying solely on advice from colleagues or unsupported personal beliefs. This approach improves patient care and empowers nurses to use and develop their clinical expertise.
Julie Grissom, RN, PhD, faculty member at the Purdue Global School of Nursing, discusses the significance and implementation of evidence-based practice in nursing.
Why Is EBP Important in Nursing?
Evidence-based practice is a framework that allows nurses to adapt their care, meet changing patient needs, and apply the latest clinical findings to real-world situations.
“EBP is the conscientious synthesis of research data, clinical expertise, and patient values — along with the theoretical influence that shapes our nursing practice,” Grissom says.
Here are five reasons why evidence-based practice in nursing is important:
1. Improved Patient Outcomes
A growing body of research indicates that EBP in nursing directly contributes to improved patient outcomes by ensuring nursing care is rooted in the most reliable and up-to-date evidence.
“Nurses who are well-educated in interpreting research data and implementing evidence-based protocols have the ability to significantly impact patient outcomes,” Grissom says. “Through education, clear communication, and the ability to identify when and where improvements are needed, they become key drivers of high-quality care.”
2. Enhanced Clinical Decision-Making
Evidence-based practice offers nurses and nursing students a structured framework for making clinical decisions. By definition, EBP ensures that nursing care and treatment decisions are guided by research findings, tested clinical experience, and patient preferences.
"EBP teaches nurses to search through research literature, critically evaluate papers, and apply that knowledge directly to their practice,” Grissom says. “This approach supports evidence-backed decisions, fostering better outcomes and greater confidence in the care provided."
3. Increased Cost-Effectiveness
Health care organizations often face pressure to balance quality care with cost efficiency. EBP can improve cost-effectiveness by minimizing unnecessary interventions and optimizing resource utilization.
“Incorporating EBP into nursing practice ensures that interventions are purposeful and supported by the latest research,” says Grissom.
4. Professional Growth and Learning
Due to the nature of evidence-based practice, nurses must stay current on the latest research and advancements in health care.
“EBP is very empowering for nurses,” says Grissom. “Engaging with EBP helps nurses expand their clinical expertise and adapt to new technologies. Staying informed on effective treatment protocols and interventions is the most important way we can provide optimal care.”
5. Building Patient Trust
Patients are more likely to trust health care providers who use evidence-based interventions.
“When patients know they are being treated with the best evidence that is current and sound, they often feel more comfortable with their care,” Grissom says. “It's the nurse's responsibility to communicate effectively and educate each patient accordingly.”
Examples of Evidence-Based Nursing Practices
The following are widely used examples demonstrating EBP in nursing:
Infection Control Protocols
Infection control protocols are derived from clinical research, data on patient outcomes, and guidelines from organizations such as the U.S. Centers for Disease Control and Prevention and World Health Organization. Examples include proper handwashing techniques, standardized steps to reduce infection rates, and isolation precautions.
Pain Management Techniques
When guided by research, clinical expertise, and patient needs, pain management is another example of EBP in nursing. In practice, this may include dispensing non-opioids to control pain when appropriate or careful opioid use guided by established practices for safety and effectiveness.
Fall Prevention Strategies
Fall prevention protocols are based on clinical research (identifying risk factors), tools that assess fall risk, and interventions that reduce fall rates. Examples include using bed alarms, offering non-slip footwear, reviewing the patient’s medications (especially sedatives), and providing assistance when walking/using the restroom.
Diabetes Management
Diabetes care is driven by clinical research trials, patient outcome data, and frequently updated clinical guidelines. Examples of evidence-based diabetes management practices include regular glucose checks, medication management, and medication adjustments based on patient response.
Balancing Patient Preference With Evidence-Based Practice
Nurses should keep the patient’s preferences in mind when providing care. “We are patient advocates first and foremost,” says Grissom. “Many times, the goal of completing protocols and checking boxes becomes paramount to what our patient actually needs. We must not forget to listen and examine every patient on a unique and holistic basis.”
Beyond listening, nurses should actively engage patients in their care, explaining the evidence behind any proposed treatments and listening to any concerns. This not only enhances the patient experience but also ensures that care aligns with their values, improving adherence and outcomes.

5 Steps for Implementing Evidence-Based Practice in Nursing
The American Nurses Association advocates the following five steps to implement evidence-based practice in nursing:
1. Ask a Clinical Question
Ask a clear question about the patient's issue and determine the ultimate goal of treatment.
2. Acquire Information
Learn more by searching for the latest clinical research from reputable sources such as PubMed, CINAHL, and Cochrane Library.
3. Appraise Search Results
Ask yourself, “Is the information valid? Is it relevant to the patient?”
4. Apply the Evidence in Practice
Make clinical decisions based on the information and your nursing expertise.
5. Assess the Provided Care
Analyze the outcomes. Was the treatment effective? Should it be considered for other patients?
