INTRODUCTION: Emergency nurses are expected to adopt evidence-based practice (EBP). The aim of this systematic review was to describe educational interventions promoting EBP and their outcomes among emergency nurses, compared with no education, to inform clinicians and researchers about effective educational interventions suitable for use in emergency departments (EDs). METHODS: CINAHL, Cochrane, PubMed and Scopus were systematically searched to identify studies published between January 1, 2006 and October 20, 2016 describing educational interventions designed to promote EBP among emergency nurses. 711 studies were identified and screened; 10 were selected for inclusion and quality assessment. The studies were analyzed using deductive content analysis, and the review's results are presented in accordance with the PRISMA guidelines. RESULTS: Ten relevant studies on nine different self-developed educational interventions were identified. Eight studies had highly significant or significant results. Interventions involving face-to-face contact led to significant or highly significant effects on patient benefits and emergency nurses' knowledge, skills, and behavior. Interventions using written self-directed learning material led to significant improvements in nurses' knowledge of EBP. All the descriptions of the interventions were incomplete, and the reported details varied considerably between the studies. CONCLUSIONS: There have been few studies on educational interventions to promote EBP among emergency nurses but the available results are promising.
