The Base Deficit, International normalized ratio and Glasgow Coma scale (BIG) score accurately predicts mortality in pediatric trauma patients. While limited in calculability, its accuracy rivals established pediatric scoring systems.
Area of Science:
- Pediatric critical care research
- Trauma patient outcomes
- Prognostic scoring systems
Background:
- Accurate mortality prediction is crucial for pediatric trauma patient selection and sample size determination.
- Existing scoring systems like PRISM III, PIM2, and PELOD are used for prognosis in pediatric intensive care units (PICUs).
- The Base Deficit, International normalized ratio and Glasgow Coma scale (BIG) score is a potential alternative for rapid mortality estimation.
Purpose of the Study:
- To compare the accuracy of the BIG score in predicting mortality in pediatric trauma patients.
- To evaluate the BIG score against established scores: PRISM III, PIM2, and PELOD.
- To assess the feasibility of using the BIG score in clinical practice.
Main Methods:
- Analysis of data from 149 PICUs between 2004 and 2015.
- Development of logistic regression models to assess mortality prediction.
- Comparison of Area Under the Curve (AUC) from Receiver Operator Characteristic (ROC) curves for each score.
Main Results:
- The BIG score was calculable for only 0.33% of the 45,377 analyzed pediatric trauma patients.
- Despite limited calculability, the BIG score demonstrated strong predictive accuracy with an AUC of 0.94.
- This accuracy was comparable to PRISM III (0.96), PIM2 (0.97), and PELOD (0.93).
Conclusions:
- The BIG score is a highly accurate tool for predicting mortality in pediatric trauma patients.
- The BIG score's accuracy supports its potential utility, despite challenges in its widespread application.
- Further research may explore methods to improve the calculability of the BIG score in diverse pediatric trauma populations.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
