An Emergency Triage Decision Making Support System In Mass Casualty Incidents

Mass casualty incident(MCI)is an event in which the number,severity and types of injuries of casualties far exceed the rescue,transit and handling capabilities of locally available emergency medical resources.In the emergency response to MCI,there are usually three issues to consider:the determination of the order of the casualties,the choice of the hospital,and the choice of transportation.Most of the existing first-aid triage methods only pay attention to the injury assessment and classification strategies of the wounded,and rarely pay attention to the subsequent more important casualty transfer and delivery process.Therefore,how to effectively allocate the hospital emergency resources and transportation resources,and develop a emergency diversion decision-making plan for large-scale casualties,so as to improve the overall treatment level of the wounded is of great significance.Based on multi-center data collection,this paper proposes a first-rate shunt decision algorithm for MCI.The algorithm takes into account the injury prediction of the casualty,the transportation capacity of the emergency vehicle,and the hospital's treatment level.The emergency personnel provided a casualty-vehicle-hospital diversion and trans-shipment decision-making scheme,and proved the effectiveness of the algorithm by comparing with the model simulation of traditional emergency triage decision.At the same time,based on this algorithm,a set of emergency triage decision support system for multiple types of users in the first-aid process of the casualty was designed and implemented,covering the entire process from on-site first-aid,wounded transportation to hospital emergency treatment,and realized the wounded medical record.The seamless docking of archives and transshipment processes and the optimal allocation of limited medical resources have improved the utilization of medical resources and improved the overall treatment level of the casualties in MCI.
