Abstract: Objective To construct the evaluation index system of the core competence of emergency trauma advanced practice nurses,and to provide reference for the training and evaluation of emergency trauma advanced practice nurses. Methods The draft of the evaluation index of the core competence of advanced practice nurses in emergency trauma was prepared by referring to domestic and foreign literature and research group discussion. From March to May 2021,18 experts were consulted by Delphi method for two rounds to complete the screening and modification of the index,and the weight of the index was determined by analytic hierarchy process. Results The evaluation index system of the core competence of advanced practice nurses in emergency trauma included 4 first-level indexes（clinical nursing practice ability,trauma nursing non-technical ability,quality continuous evaluation ability,professional development ability）,14 second-level indexes and 42 third-level indexes. The authority coefficients of the two rounds of expert consultation were 0.914,and the effective response rates were 100%. The Kendall harmony coefficients of the first,second and third indexes of the second round of expert consultation were 0.056,0.187 and 0.216,respectively（all P< 0.001）. Conclusion The evaluation index of the core competence of advanced practice nurses in emergency trauma is scientific,reasonable,comprehensive and targeted,which can provide reference for the training and evaluation of advanced practice nurses in emergency trauma.
