pediatric_big_score: Pediatric Trauma BIG Score

Description

Calculates the BIG Score (Base deficit, INR, Glasgow coma scale) to predict in-hospital mortality in pediatric trauma patients. This rapid stratification tool uses admission laboratory and clinical values to identify children with a high risk of death.

Usage

pediatric_big_score(base_deficit, inr, gcs)

Value

A list containing:

BIG_Score

The calculated score.

Risk_Category

Risk stratification based on the threshold of 16.

Mortality_Prediction

Estimated mortality risk category.

Arguments

base_deficit

Numeric. Admission base deficit in mmol/L (or mEq/L). Enter as a positive value representing the deficit (e.g., if Base Excess is -10, enter 10).

inr

Numeric. Admission International Normalized Ratio.

gcs

Numeric. Admission Glasgow Coma Scale score (3-15).

Examples

# Example 1: Low Risk
# Base Deficit 2, INR 1.1, GCS 15
# Score = 2 + (2.5 * 1.1) + (15 - 15) = 2 + 2.75 + 0 = 4.75
pediatric_big_score(2, 1.1, 15)

# Example 2: High Risk
# Base Deficit 10, INR 1.8, GCS 8
# Score = 10 + (2.5 * 1.8) + (15 - 8) = 10 + 4.5 + 7 = 21.5
