Clinical Report: Nomogram for Predicting 30-Day Mortality in Pediatric TBI

Overview

This study developed a clinical nomogram to predict 30-day in-hospital mortality in pediatric patients with moderate-to-severe traumatic brain injury (msTBI). The model demonstrated strong predictive performance with an AUC of 0.898, incorporating key clinical variables.

Background

Traumatic brain injury (TBI) is a leading cause of death and disability in children, necessitating effective risk stratification tools. With a significant proportion of pediatric TBI cases classified as moderate-to-severe, early identification of high-risk patients is crucial for improving outcomes. Existing prediction models have limitations, highlighting the need for a robust tool like the nomogram developed in this study.

Data Highlights

Key Findings

• The nomogram predicts 30-day in-hospital mortality in pediatric msTBI patients.
• Four independent predictors were identified: Glasgow Coma Scale score, lactic acid, albumin, and trauma-induced coagulopathy.
• The model achieved an AUC of 0.898, indicating excellent predictive accuracy.
• Good calibration was confirmed by a non-significant Hosmer-Lemeshow test (P = 0.475).
• Clinical decision analysis indicated a threshold probability ranging from 0 to 0.95.

Clinical Implications

The nomogram serves as a valuable tool for clinicians to identify high-risk pediatric patients with msTBI, facilitating early intervention and tailored treatment strategies. By integrating key clinical variables, it enhances decision-making in acute care settings.

Conclusion

The developed nomogram provides a reliable method for predicting 30-day in-hospital mortality in children with msTBI, supporting improved clinical outcomes through early risk assessment.
