A nomogram for calculation of the Revised Baux Score

Area of Science:

• Medical assessment
• Clinical prediction tools
• Burn patient management

Background:

• The revised Baux score is a widely adopted tool for predicting mortality in burn patients.
• Its reliance on complex calculations limits practical clinical application without specialized tools.
• There is a need for a more accessible method for calculating the revised Baux score in real-time clinical settings.

Purpose of the Study:

• To develop and validate a nomogram for accurate and efficient calculation of the revised Baux score.
• To provide a user-friendly alternative to complex statistical calculations for burn patient mortality prediction.
• To assess the accuracy, reliability, and ease of use of the developed nomogram.

Main Methods:

• Design of a nomogram based on the revised Baux score formula.
• Evaluation of the nomogram's performance using randomly generated patient data.
• Statistical analysis of nomogram accuracy, including bias and limits of agreement.

Main Results:

• The developed nomogram accurately calculates the revised Baux score.
• The nomogram demonstrated a minimal bias of -0.003 percentage points.
• Limits of agreement were -0.3619 to 0.3550, with a repeatability coefficient of 0.29 percentage points.

Conclusions:

• The nomogram is an accurate, cost-effective, and rapid tool for assessing burn patient mortality.
• Its ease of use makes it a valuable adjunct in the initial assessment of burn patients.
• The nomogram can serve as a reliable method for cross-checking other mortality prediction calculations.
