The Impact of Evidence-Based Nursing Practice on Patient Outcomes and Healthcare Quality: A Systematic Review

Abstract

Background: Evidence-Based Nursing Practice (EBNP) is a critical approach that integrates the best available evidence, clinical expertise, and patient preferences to improve healthcare delivery.

Objective: To systematically evaluate the impact of EBNP on patient outcomes and healthcare quality.

Methods: A systematic review was conducted following PRISMA 2020 guidelines. Databases including PubMed, Scopus, CINAHL, and Web of Science were searched for studies published between 2016 and 2025. Eligible studies assessed the effects of EBNP interventions on clinical, safety, or patient-centered outcomes.

Results: The included studies consistently showed that EBNP improves patient outcomes, including reduced mortality, decreased hospital-acquired infections, shorter length of hospital stay, and enhanced patient satisfaction. EBNP also contributed to improved healthcare quality through better clinical decision-making, standardization of care, and reduction in medical errors.

Conclusion: EBNP plays a vital role in enhancing patient outcomes and healthcare quality. However, its effectiveness depends on organizational support, continuous training, and integration of evidence into daily nursing practice.
