[Scoring systems for evaluating injury severity]

Abstract

Introduction: Various trauma scoring systems were developed in order to assess injury severity and aid in decision making regarding further therapy and probable outcome.

Anatomic injury severity scales: AIS--Abbreviated Injury Scale is a summary of all the values (from 1-9) for each organ or body part that is injured. ISS--Injury Severity Scale scores three dominant injuries from AIS scale. The maximum score for ISS is 75. MISS--Modified Injury Severity Score is a square of the AIS value for the three body parts with most severe injuries.

Physiologic injury severity scales: GCS--Glasgow Coma Score is a numerical scale that assesses the severity of CNS injuries, that is the most appropriate system for numerical assessment of consciousness disturbance. Trauma score is a sum of GCS decreased for 1/3, plus the assessment of cardiopulmonary function. COMBINED ANATOMIC-PHYSIOLOGIC SCORING SYSTEMS: TRISS score (TS-ISS--trauma and injury severity score) TRISS combines ISS, TS, age of the patient and mechanism of injury, in order to determine survival probability. PTS--Pediatric Trauma Score takes into consideration all of the peculiarities of pediatric patients in response to trauma. Score values are from -6 to +12. APACHE--Acute Physiology And Chronic Health Evaluation Although it is complicated for general use, it still represents the most commonly used scoring system in Intensive Care Units.

New scoring systems: MPM--Mortality Probability Models. MODS--Multiple Organ Dysfunction Syndrome. LODS--Logistic Organ Dysfunction Syndrome. SAPS--Simplified Acute Physiologic Score.
