Injury Severity Score Worksheet

The ISS measures the overall severity of injuries sustained by a patient, calculating a numerical value based on the most severe injuries across different body regions to predict treatment outcomes and mortality.

The ISS is calculated by squaring the highest Abbreviated Injury Scale (AIS) scores from each of the three most severely injured body regions and then summing these squares, providing a score ranging from 1 to 75.

Yes, the ISS is often used to estimate the length of hospital stay, as higher scores generally correlate with longer recovery times and more extensive medical care.
