Abstract: Objective To construct a midwifery training mode based on in-situ simulation, and to evaluate its quality and application effectiveness. Methods The in-situ simulation emergency training course was constructed after literature review and qualitative research interview. The course was applied in a tertiary grade-A maternal and child health hospital in Henan Province from April to December 2022. Training quality and core competency were evaluated using a revised version of the Simulation Effectiveness Tool Modified (SET-M) and the Midwifery Core Competency Scale. Results Six sets of in-situ simulation training courses for nurse specialists of midwifery were constructed in this study. After training, each item in the revised scenario simulation effect evaluation table of midwifery nurse specialists scored more than 2 points, and the score of each dimension of core competency was higher than that before training (P<0.05). Conclusion The training mode for midwifery nurse specialists based on in-situ simulation can significantly improve the core competency of midwives and provide corresponding reference for on- job training for nurses.
