This study aimed to evaluate hospital nurses’ perception of evidence-based practice. Materials & Methods: This descriptive-analytical study was conducted in 2015 on 374 nurses randomly recruited from five teaching hospitals in Ardabil and Khalkhal, Iran. Data were collected using the Evidence-Based Practice Questionnaire and analyzed through the SPSS software (v.13.0). Results: The total mean scores of nurses’ perception of evidence-based practice and its practice, attitude, and knowledge/skills domains were 107.40±18.76, 4.66±1.34, 3.63±1.48, and 4.63±1.03, respectively. The mean scores of these domains had significant correlations with each other (P<0.05). Conclusion: Nurses’ perception of evidence-based practice is at moderate level and hence, they have moderate readiness for evidence-based practice. Coherent policies, educational strategies, and environmental improvements are needed to improve nurses’ perception of evidence-based practice. Key words: perception; evidence-based practice; nurses Introduction 1 Nurses constitute the biggest group of healthcare providers worldwide. They are responsible for the provision of about half of all healthcare services. Therefore, the quality of healthcare services largely depends on the quality of nursing care services (1). Because of their critical roles in care delivery, nurses need to continuously develop their knowledge and skills and keep their knowledge up-to-date (2). They need to acquire knowledge about the newest evidence on nursing practice (4). *Corresponding Author: Khadijeh Nasiri, Postal Address: Department of Medical Surgical, Khalkhal University of Medical Sciences, Khalkhal, Iran. Email: khadije.nasiri@yahoo.com The American Association of Colleges of nursing introduced the ability to provide evidence-based nursing care as a striking characteristic of quality nursing care (3). Thus, healthcare providers have become interested in evidence-based practice (EBP) (5, 6). Tehran University of Medical Sciences Nurs Pract Today. 2019; 6(2):94-99. Nurses consider professional care delivery, patient-centeredness, and quality care as the core concepts of EBP (7, 8). However, the aim of EBP is to use knowledge and the results of the latest clinical researches based on patient’s conditions in order to provide healthcare services (9–11). EBP has four main phases, namely changing a clinical scenario to an answerable and organized question, searching the literature to find the best evidence for answering the question, critical appraisal of the evidence to assess
