Samenvatting
As the effects on injury scaling of the differences between the 1980 revisions of the AIS are unknown in blunt trauma, 1270 critically injured (median ISS, 26) blunt trauma patients were compared. In 911 patients (72%) there were no differences between AIS- 80 and AIS- 85 in any body region or in derived ISS. Changes in AIS grades were most common in the Abdomen (205 patients), Thorax (100 patients) and Head (61 patients)regions.
