Abstract: Objective To construct the post competency model and a system with first, second and third-level indexes for new nurses in maternity and children’s hospital and to provide theoretical basis for job training of new nurses. Methods After literature review, from February to May 2020, the competency model index system of new nurses in maternity and children’s hospital was established based on onion model. Two rounds of expert consultation were conducted among 33 nursing experts using the Delphi method. Results The effective recovery rate was 100%, showing high positive coefficient. The authority coefficient (Cr) was 0.825 and the degree of authority and coordination of experts was high (P<0.05). The developed competency model index system consisted of 4 first-,15 second- and 32 third-level indexes. Conclusion With high positive coefficient and high degree of authority and coordination, the competency model and index system of new nurses in maternity and children’s hospital are practical, which provides scientific theoretical basis for post training of new nurses.
