Objective:To construct an evaluation index system for the core competence of emergency medical dispatchers, so as to provide a theoretical basis for the training, assessment and ability evaluation of emergency medical dispatchers.Methods:In September 2022, a research group was established to compile the first draft of the evaluation index system for the core competencies of emergency medical dispatchers through literature review, semi-structured interviews and group discussions. From October to November 2022, a total of 27 experts in related fields from nine provinces and municipalities directly under the Central Government in China were consulted by Delphi expert letters, items were screened and amended, and an evaluation index system for the core competence of emergency medical dispatchers was formed.Results:A total of two rounds of correspondence were conducted. The effective recovery rate of the questionnaire was 100%, and the authority coefficient of the experts was 0.856. Kendall's coordination coefficients were 0.402 and 0.414 ( P<0.01), respectively. Finally, a core competency evaluation index system for emergency medical dispatchers was constructed, which included seven primary indicators, 16 secondary indicators and 75 tertiary indicators. Conclusions:The core competence evaluation index system for emergency medical dispatchers is scientific, reliable and comprehensive, which can provide a theoretical basis for the training, assessment and ability evaluation of emergency medical dispatchers.
