Abstract: Objective To retrieve and summarize the best evidence of communication strategies for emergency department nurses' participation in end-of-life care（EoLC）. Methods We established evidence-based problems. According to the "6S" evidence model,we searched from top to down,including UpToDate,BMJ best clinical practice,British National Institute for Health and Care Excellence（NICE）,Canadian Ontario Registered Nurses Association（RNAO） website,International Guide Network,Australian Joanna Briggs Institute（JBI） Evidence-based Health Care Center Library,Cochrane Library,PubMed,Web of Science,Embase,CINAHL,Wanfang Database,CNKI,VIP Database,CBM,Yimaitong and other databases and websites for relevant literature on the communication strategy of emergency nurses' participation in EoLC which included clinical decision-making system,practice guidelines,evidence summary,consensus,and systematic review. The retrieval time was from the establishment of the database to March 2023.Two researchers who received training in evidence-based medicine used the literature evaluation criteria and evidence grading system of JBI evidence-based health care center to evaluate literature quality and evidence level,and extract,induce and summarize evidence according to the topic. Results 10 articles were finally included,including 2 guidelines,3 clinical decisions,5 systematic evaluations,and 29 pieces of evidence were summarized. Conclusion The formation of best evidence for emergency nurses to participate in the EoLC communication strategy is rigorous and scientific,with a certain clinical practicability. Emergency medical staff need to combine cultural background,clinical situation and patient opinions to provide targeted EoLC services for terminally ill patients.
