Purpose of scoring systems appropriate triage and classification of trauma patients predict outcomes for patient and family counseling quality assurance research (extremely useful for the study of outcomes)
Classifications
Physiologic Revised Trauma Score (RTS) Acute Physiology and Chronic Health Evaluation (APACHE) Sequential Organ Failure Assessment Score (SOFA) Systemic Inflammatory Response Syndrome Score (SIRS) Emergency Trauma Score
Combined Trauma Score - Injury Severity Score (TRISS) A Severity Characterization of Trauma (ASCOT) International Classification of Diseases Injury Severity Score (ICISS) Ganga Hospital Open Injury Score (GHOIS)
quantifies severity of head injury by measuring CNS function initial assessment tool continual re-evaluation of head injured patients
GCS ( Glasgow Coma Scale)
Interpretation brain injury severe <9 moderate 9-12 minor 13 and above
Revised Trauma Score (RTS) most widely used prehospital field triage tool
Injury Severity Scale (ISS) first scoring system to be based on anatomic criteria defines injury severity for comparative purposes based on scores of 9 anatomic regions head face, neck, thorax, abdominal and pelvic contents, spine, upper extremity, lower extremity, external
Abbreviated Injury Scale (AIS) grades 0 - no injury 1 - minor 2 - moderate 3 - severe (not life-threatening) 4 - severe (life-threatening, survival probable) 5 - severe (critical, survival uncertain) 6 - maximal, possibly fatal
Injury Severity Scale (ISS) ISS = sum of squares for the highest AIS grades in the three most severely injured ISS body regions ISS = A 2 + B 2 + C 2 where A, B, C are the AIS scores of the three most severely injured ISS body regions scores range from 1 to 75 single score of 6 on any AIS region results in automatic score of 75 ISS > 15 associated with mortality of 10%
Mangled Extremity Severity Score (MESS) -used to predict necessity of amputation after lower extremity trauma skeletal and soft tissue injury (graded 1-4) limb ischemia (graded 1-3) shock (graded 0-2) age (graded 0-2) score of >7 is predictive of amputation score determined by adding scores of components in four categories
