A hospital disaster drill is commonly carried out based on the activities assigned beforehand by the occupational description. However, it is difficult for each staff the role is fixing to understand the global image of a disaster correspondence in a hospital disaster when their role is assigned and fixed. We have developed the understandable drill about the whole practice at each hospital in disaster. We keenly realized the necessity of a standard disaster medicine. Therefore we have developed the disaster drill which can be held per hospital. As a goal of a course, each hospital personnel could understand the global image of the disaster, and aimed at the daily course which can master necessary minimum skill to correspond a disaster in each hospital. From the reasons above, we created the course which consisted of a lecture, individual skill training, and a gross training. As essential skill, it starts with (1) management of disaster countermeasures office (2) management of triage post (3) treatment at room (4) support of conveyance between hospitals (5) information control. In order to employ these individual skill booths efficiently we divided attendances into five groups. Five hospitals started from 2008, were carried out 11 times, and about 500 persons took this disaster drill on a course. We expect that cost to bellower, the course to be simpler, and the quality of training will improve by holding this course repeatedly.
