Study on Disaster Medical Response During the Great East Japan Earthquake Disaster Based on Essential Elements of Information – Nine Days at Iwate Prefecture from Hyperacute Phase to Subacute Phase –

During the Great East Japan Earthquake Disaster, the medical team's responses in Iwate Prefecture Disaster Emergency Operations Center experienced various difficulties, especially during the first 9 days. In this paper, we propose to objectively reveal problems of response activities from the viewpoint of operational information processing by the After Action Review, focusing on the activity logs in the time series (chronologies). By using Essential Elements of Information (EEI) as a framework of our analysis, we clarified the gap between the task that should be performed and the actual conditions in the operation of Japan Disaster Medical Assistance Team (DMAT), from the hyperacute phase to the subacute phase of medial responses.
