Injury Severity Scoring in the Resuscitation Room—Is Preliminary Injury Severity Score Accurate?

This study found a moderate but overall acceptable level of agreement between preliminary and definitive ISS in trauma patients. In the most severe cases, the preliminary ISS showed a tendency to underestimate injury severity. These findings suggest that the accuracy of preliminary ISS diminishes in cases of severe trauma, highlighting the need for cautious interpretation in critically injured patients. Preliminary ISS remains a valuable tool in clinical settings for trauma severity classification.
