Disaster Medical Responses to the Disaster Scene of Long-distance on Highway-Field Triage and Disaster Communication by Social Media for 106-vehicle Chain Collision in Yeong- Jong Grand Bridge

ABSTRACT

PURPOSE: This study describes the disaster medical responses to the disaster scene of long-distance on a highway; 106-vehicle chain collision on Yeong-Jong Grand Bridge on February 11, 2015 and we discuss the disaster communication by social media. METHODS: Records of disaster medical responses from records of relevant organizations and messages of social media were collected. Medical records and the results of triage were reviewed retrospectively. Casualties were categorized into four groups according to results of triage; Red- Yellow-Green-Black. Kappa statistics were used to measure agreement between results of triage and casualties' outcome. RESULTS: Disaster Medical Assistant Team (DMAT) arrived on the scene one hour after accidents occurred. DMAT settled in a temporary base camp in the middle part of the scene and did not build an emergency air shelter. DMATs from four hospitals were separated into four mobile units of DMAT and they joined the rescue team. Disaster communication by social media was useful. Seventy six casualties were transported and two died; 28.9% of casualties were transported to the nearest regional emergency medical center; 20.0% of red casualties were transported to a higher level of care again. Kappa statistics were 0.122 (95% CI, - 0.049~0.291; p=0.094). CONCLUSION: In the disaster scene of long-distance on a highway, adequate location of triage and treatment area may be the front or rear of the scene and separation of DMATs can be helpful. Disaster communication by social media was helpful. Education and policies will be required for more effective triage and dispersion of casualties.
