Dia Gainor, NASEMSO
National EMS System Information System (NEMSIS) Version 3.0 Compliant Out-of-Hospital Records
Emergency Department Discharge Databases
Hospital Discharge Databases Trauma Registries
Physiological scoring systems Glasgow coma scale Trauma score Revised trauma score TRISS methodology
Anatomical scoring systems Abbreviated injury score Injury severity scoreICD-9 Injury Severity Score
Calibrated by the Association for the Advancement of Automotive Medicine
First developed in 1969 Anatomically based Consensus derived Updated every five years Has been adopted by numerous
other countries
1 = Minor 2 = Moderate 3 = Serious 4 = Severe 5 = Critical 6 = Maximum (Untreatable)
Head/neck Face Chest Abdomen Extremity External (skin)
ONLY highest AIS number in each body area is used
3 most severely injured body region scores squared
3 squared scores added together
= Injury Severity Score
If injury is assigned a 6 (unsurvivable), ISS automatically = 75
Score Reflective of Injury Severity 1 - 9 Minor 10 - 15 Moderate 16 - 24 Moderate/Severe ≥ 25 Severe/Critical
Many different injury patterns yield same ISS score
Errors of AIS scoring = errors of ISS
Injuries to different body regions are not weighted
Limits the number of contributing injuries to 3
Can’t account for multiple injuries to the same body region
Anatomical scoring system for patients with multiple injuries
ISS score correlates with mortality, morbidity & hospital stay
Bivariate correlation of mortality % with ISS and age
