Objectives The purposes of this study was to identify factors influencing the evidence-based practice(EBP) com-petency of nurses in general hospitals with fewer than 300 beds. Methods For this purpose, EBP beliefs, EBP knowledge/skills, EBP organizational readiness, and EBP competency were measured using a structured questionnaire targeting 178 nurses at a general hospital with less than 300 beds in G City. After analysis using descriptive statistics, independent t-test, and ANOVA using the SPSS 27.0 program, post-hoc testing was performed using the Scheffé test, and analysis was conducted using Pearson’s correlation coefficient and hierarchical multiple regression analysis. Results As a result of the study, significant differences in EBP competency according to the subjects' general and EBP-related characteristics were age, rank, total clinical experience, and presence of EBP training experience. EBP competency was found to have a significant positive correlation with EBP beliefs, EBP knowledge/skills, and EBP organizational readiness. As a result of performing a hierarchical regression analysis by inputting control vari-ables and independent variables, the factors affecting EBP competency appeared in the following order: EBP or-ganizational readiness, EBP knowledge/skills, EBP beliefs, rank of head nurse or higher, and EBP training experi-ence, and the final model The explanatory power was 55.9%. Conclusions In order to improve the EBP competency of nurses in general hospitals with less than 300 beds, the development and education of nursing interventions that can increase knowledge/skills through positive EBP be-liefs are necessary, and active support efforts are required from the nursing department and hospitals at the or-ganizational level.
