new technologies in communications, the Internet, computer miniaturization, and advanced “smart devices” have the potential to vastly improve the emergency medical response to such mass-casualty incident disasters. In particular, next-generation wireless Internet and geopositioning technologies may have the greatest impact on improving communications, information management, and overall disaster response and emergency medical care. These technologies have applications in terms of enhancing mass-casualty field care, provider safety, field incident command, resource management, informatics support, and regional emergency department and hospital care of disaster victims.
