[Injury severity score (ISS) in evaluation of patients with multiple injuries].

Since there are short comings in injury severity score (ISS) for evaluation of multiple injuries. We modified it 482 cases by expanding the 3 injury sites of 3 main areas of ISS to 7 injury sites in 4 areas. Comparison of the two scores showed that in ISS, only 72.84% of the injuries were shown and in the modified about 97.56%. Statistical analysis and clinical observations indicated that that RISS is accurate in evaluating patients with multiple injuries.
