Development and Social Implementation of D24H - Disaster/Digital Information System for Health and Well-being

Introduction: D24H - Disaster/Digital Information System for Health and Well-being - was initiated in 2018 to provide information support for health, medical, and welfare activities during disasters and became fully operational in 2024. Integrated with the SIP4D (Shared Information Platform for Disaster Management) disaster information database, D24H customizes and delivers disaster-affected area information tailored for health, medical, and welfare supporters. During the Noto Peninsula Earthquake on January 1, 2024, D24H was deployed to share critical information, including electricity and water supply statuses, road damage, and updates on medical institutions and shelters, thereby supporting the disaster-stricken area. Methods: D24H comprises a database using Geographic Information Systems (GIS), tools for conducting field surveys in disaster-affected areas, and features for file and task sharing, as well as communication among support personnel. The system’s functionalities were designed based on interviews with key stakeholders, including DMAT, DHEAT, DWAT, and the Japanese Red Cross Society, which are involved in health, medical, and welfare support activities during disasters. Results: Information on disaster-affected areas can now be visualized on maps and summarized in a dashboard using indicators, aiding the Health, Medical, and Welfare Coordination Headquarters in gaining an overview of the affected region. The survey tool implemented a smartphone-based input system, allowing flexible customization of survey targets and items as needed. Interviews revealed high expectations for the implemented file-sharing and communication tools. Conclusion: D24H, deployed during the Noto Peninsula Earthquake, successfully visualized the situation in the disaster-affected area and contributed to health crisis management activities for disaster victims. However, due to a lack of adequate training and practice opportunities before deployment, not all functionalities were fully utilized. Since the earthquake, many health, medical, and welfare supporters have inquired about training and workshops. By acquiring proficiency in D24H through training and exercises, stakeholders can better prepare for future disasters.
