Educational results of the Japan Maternal Emergency Life‐Saving (J‐MELS) simulation training organized by Japan Council for the Implementation of the Maternal Emergency Life‐Saving System (J‐CIMELS): a 12‐month longitudinal follow‐up study in Japan

Abstract Aims This study aimed to evaluate the long‐term results of Japan Maternal Emergency Life‐Saving (J‐MELS) simulation training on obstetric healthcare providers, over a 12‐month follow‐up period. Methods A total of 273 trainees from 17 J‐MELS Basic courses conducted between August 2021 and October 2023 were included. The trainees' responses to the pre‐ and post‐tests, questionnaires, and self‐reports on the usefulness of the J‐MELS scenarios in actual clinical settings at 1, 6, and 12 months after the training were analyzed. Multivariate logistic regression analysis was also conducted to identify the factors influencing knowledge retention. Results We found an overall improvement in clinical knowledge acquisition after J‐MELS training and a significant retention of this improvement at least until 12 months later. However, these scores gradually declined over. Trainees reported increased usefulness of J‐MELS scenarios in actual clinical practice at 1, 6, and 12 months after training, particularly in managing obstetric emergencies such as atonic postpartum hemorrhage. Knowledge retention was influenced by several specific factors, such as years of clinical experience, affiliated institutions, qualifications, and especially pre‐test scores. Conclusion Our longitudinal follow‐up study demonstrated, for the first time, the long‐term results of J‐MELS simulation training using post‐tests and self‐report data. Our findings provide valuable insight into the impact of J‐MELS simulation training on maternal emergency care. By elucidating the factors influencing knowledge retention and practical utility, the findings offer actionable recommendations for optimizing training strategies and improving maternal outcomes in actual clinical practice.
