High-fidelity Multidisciplinary Competition-based Simulation Tasks in Prehospital Emergency Medical Service

抄録・要旨

Introduction: Simulation task teams were conducted, with each team consisting of a medical doctor, a nurse, an emergency life-saving technician, and an ambulance crew certified for rescuer tasks. The scenarios were competitive, using high-fidelity manikins and standardized actor patients on-site and at stations, referred to as Rallye Medicina. This study aimed to evaluate tasks in a Japanese medical rally in 2019 for effectiveness. Multiple attribute utility technology was used, as the task was intended to achieve multiple goals. Subjects and Methods: Three tasks ̶ pediatric emergency care, care of injured drivers in traffic accidents, and response to multiple casualties in terrorism̶out of seven drills were analyzed. Four goals̶improving teamwork within the emergency response team, enhancing emergency care skills, increasing patient survival rates, and building public trust in emergency care̶were determined. Five stakeholder groups consisting of four types of emergency professionals, one administrator group, and a panel of emergency medical doctors specializing in medical rally, were designated. Stakeholders determined the relative importance of the goals, and the panel assessed the goal achievement rate based on the actual and target values of each achievement. Utility scores for tasks were calculated by group. Results: Utility scores in the groups, overall, were as follows: 80.2 for pediatric care, 79.1 for drivers’ care, and 88.5 for mass casualty response. All five groups had the highest utility score for mass casualty response among the tasks, with the same priority order. Conclusions: Conducting and participating in the medical rally achieve goals in real-world settings. Simulation tasks would be crucial for the education and revision of local institutions’ plans for emergency preparedness, with consideration for potential disasters such as mass casualties.
