The medical severity index of disasters

In 1980 an international working party postulated a definition for a disaster. Later this concept was formulated into a classification and scoring system. This system has now been refined to be used prospectively during the management stage of a calamity. By calculating the medical severity index, which is the product of the casualty load and the severity of the incident, and comparing this figure with the available total capacity of the medical services, which is the medical rescue capacity, the medical transport capacity and the hospital treatment capacity, the dispatcher at the control center can fairly quickly and precisely identify if a calamity is to be regarded as a disaster or not and if the region can cope with the situation. Moreover a calculation of the hospital treatment capacity in the region could serve as a guideline for estimation of the dimensions needed for the medical rescue capacity and medical transport capacity when planning how to deal with a disaster.
