Objective To understand the status of evidence-based practice ability of emergency nurses,and to explore its possible influencing factors. Methods By convenience sampling,a cross-sectional survey of 236 nurses from 46 hospitals in Guangxi was conducted using the Chinese version of Evidence Based Practice Evaluation Competence Questionnaire（EBP-COQ）. Results The total average score of EBP-COQ of emergency nurses was（3.43±0.35）,and the average scores of all dimensions were（3.77±0.37） for total,（3.34±0.49） for knowledge,and（3.17±0.47） for skill. Multiple linear regression analysis showed that educational background had significant effect on the total score of the EBP-COQ;educational background,and whether there was a certificate of emergency specialist nurses affected evidence-based practice attitudes;age affected evidence-based practice knowledge. In recent 5 years,the number of papers published as first author or corresponding author affected evidence-based practical skills. Conclusion At present,emergency nurses in Guangxi can treat the practice of evidence-based nursing positively,but the whole level of evidence-based practice ability needs to be improved. According to the weakness of evidence-based practice ability,the training plan can be formulated to improve the evidence-based practice ability of emergency nurses,and promote evidence-based practice in clinical practice all-round development.
