Large quantities of medical resources are necessary for the treatment of pa
tients suffering from acute radiation syndrome in combination with blast an
d thermal injuries (combined injuries). So far, however, there is no tool a
vailable for evaluating the resources required for the treatment of combine
d injuries. The purpose of this manuscript is to describe the scientific ba
sis for a newly developed software tool designed to estimate the medical re
sources needed for treating the combined injuries of individuals/high numbe
rs of casualties who may be involved in civil defense, emergency medical ca
re and various military activities (namely out of area) in the case of a nu
clear event. (C) 1999 Elsevier Science Ltd. All rights reserved.
