  • Rate only the most severe injury from each body system.

  • While this score has primarily served research purposes, there may be clinical prognostic application in the ICU following initial stabilization of traumatic injuries. Calculation of the ISS should not affect initial management of traumatic injuries.

  • Standard of care for all trauma patients includes an initial treatment strategy focused on the primary and secondary survey, in addition to assessing and stabilizing the patient.

Introduction
The ISS was developed primarily as a research tool to standardize the study of trauma patients. It is not intended for bedside decision-making in the context of a single patient. Therefore, the calculation of the ISS should not impact initial management of the patient with traumatic injuries. The priority in all trauma patients is conducting the primary and secondary survey and stabilization of traumatic injuries. However, it may have application in the clinical setting following initial stabilization of traumatic injuries. 

The initial population focus of the ISS was patients with blunt trauma from motor vehicle accidents only.

Formula

1. Select the Abbreviated Injury Scale (AIS) Score that represents the most severe injury in each body system (below).

Severity

AIS

No injury

0

Minor

1

Moderate

2

Serious

3

Severe

4

Critical

5

Unsurvivable

6

 

2. If the 3 most severe injuries in 3 body systems are A, B, and C, then

3. ISS=A² + B² + C² 

Scoring

  • The ISS gives equal importance to each body region.

  • A score of 6 (Unsurvivable) in any body system will automatically assign an ISS of 75, which is the maximum possible score.

  • The ISS is calculated only from the three most severe injuries.
