A Study on Disaster Medical Response During the Great East Japan Earthquake Disaster Based on the Emergency Support Function – Nine Days at Iwate Prefecture from Hyperacute to Subacute Phase –

During the Great East Japan Earthquake Disaster, the medical team’s responses in the Iwate Prefecture Emergency Operation Center (EOC) experienced many difficulties, especially in the first nine days after disaster occurrence. In this paper we proposed to objectively reveal problems of response activities at the viewpoint of information processing by the After Action Review (AAR), focusing on the activity logs in the time series (chronologies). By using the Emergency Support Function (ESF) as a framework of our analysis, we clarified the gap between the task that should be performed and actual conditions in the operation of the Japan Disaster Medical Assistance Team (DMAT) from the hyperacute phase to the subacute phase of medical responses.
