Introduction:Technology has transformed healthcare, yet the COVID-19 pandemic revealed critical gaps in its integration, especially in emergency response. Mass casualty incidents (MCIs), caused by disasters or large-scale accidents, overwhelm emergency services and demand coordinated triage and resource management. Purpose:This scoping review examines how technology is used to train, assess, or evaluate prehospital responders in MCIs, identifying types of technologies, training approaches, and gaps in implementation, scalability, and learner inclusion. Methods:Following Arksey and O’Malley’s framework (with Levac’s refinements) and PRISMA-ScR guidelines, the review will include studies involving technological tools applied to MCI training or evaluation of prehospital providers. A comprehensive database search will support thematic analysis of included literature.
