Abstract: Objective: To analyze the behavior of evidence-based nursing and the influencing factors among nurses in tertiary hospitals, in order to provide a basis and reference for the scientific and effective implementation of training on the evidence-based nursing research capabilities of nurses. Methods: A total of 866 nurses were recruited from tertiary hospitals from October to December 2024 through convenience sampling. Questionnaires used in this study were the Evidence-based Practice Questionnaire, the Barriers to Research Utilization Scale, and the Facilitators of Research Utilization Scale. Besides, participants' demographic characteristics were also collected. Multiple linear regression was used to analyze the influencing factors of evidence-based practice behavior. Results: The mean scores of behaviors, attitudes, and knowledge towards evidence-based nursing were 4.77±1.44, 4.87±1.36, and 4.50±1.18, respectively. Age, nurses' knowledge and attitudes of evidence-based nursing were the influencing factors of behaviors of evidence-based nursing. The greatest barrier to research utilization was the communication factors. The top two factors that could facilitate research utilization were leaders' support and encouragement and a capable nurse as the group leader. Conclusion: The level of behaviors of evidence-based nursing among nurses in tertiary hospitals remains to be improved. Nurses' age, knowledge and attitudes of evidence-based nursing were the influencing factors of behaviors of evidence-based nursing. Continuing education and training are expected to improve the knowledge, attitudes, and behaviors of evidence-based practice among nurses.
