The BIG Score and In-Hospital Trauma Mortality

Summary

This study investigated the efficacy and reliability of the BIG score, calculated based on the base deficit (BD), International Normalized Ratio (INR), and Glasgow coma scale (GCS), in comparison with the GCS, Revised trauma score (RTS), and Injury Severity Score (ISS) for predicting in-hospital mortality in adults with multiple-trauma presenting to the emergency department (ED).

BIG SCORE

The trauma BIG score is used to predict posttraumatic injury severity and mortality. It was originally designed for the pediatric population. The score is calculated using the Base Deficit (BD), International Normalized Ratio (INR), and Glasgow Coma Scale (GCS) score on admission using the following formula: BIG score = (admission BD) + (2.5 × INR) + (15 - GCS).

OTHER

Glasgow coma scale

The Glasgow Coma Scale is a neurological assessment tool used to evaluate the level of consciousness of a patient. It assesses three items: eye-opening (spontaneous, 4 points; to verbal stimuli, 3 points; to pain stimuli, 2 points; no response, 1 point); verbal responses (oriented, 5 points; confused but coherent speech, 4 points; inappropriate words, 3 points; incomprehensible speech, 2 points; no response, 1 point); and motor responses (obeys commands, 6 points; localizes pain, 5 points; withdraws from pain, 4 points; flexes in response to pain, 3 points; extends in response to pain, 2 points; no response, 1 point). The total GCS score is obtained by summing the scores for the three items, and it ranges from 3 to 15.

OTHER

Revised Trauma Score

The Revised Trauma Score (RTS) is a physiological scoring system used to assess the severity of a traumatic injury. It considers three key parameters, Glasgow Coma Scale (GCS), Systolic Blood Pressure (SBP), and Respiratory Rate (RR), with a total score of 12 points. The study team retrospectively computed the RTS on admission by retrieving the GCS score, SBP, and RR per minute from the hospital's automated systems and archives.

OTHER

Injury Severity Score

The Injury Severity Score (ISS) is an anatomical scoring system used to assess the severity of injuries sustained by trauma patients. It provides a numerical value based on the anatomical regions of the body affected by trauma and the severity of those injuries. The ISS is calculated by dividing the body into six regions: the head/neck, face, chest, abdomen/pelvis, extremities, and external. Each region is assigned a score ranging from 1 to 6, with 1 indicating minor injury and 6 indicating severe injury. The highest score from each region is squared and then the scores are summed to calculate the overall ISS.
