The pediatric glucocorticoid toxicity index.

Area of Science:

• Pediatric medicine
• Clinical outcome assessment
• Pharmacovigilance

Background:

• Glucocorticoids (GCs) are crucial for treating pediatric inflammatory diseases but can cause significant toxicity.
• Assessing and quantifying GC-induced toxicity in children requires a standardized, dynamic tool.
• Existing methods may not adequately capture the nuances of GC toxicity in pediatric populations.

Purpose of the Study:

• To develop and validate a Pediatric Glucocorticoid Toxicity Index (pGTI).
• To create a standardized, weighted clinical outcome assessment for measuring GC toxicity changes over time in pediatric patients.
• To establish a digital platform for accurate and user-friendly toxicity assessment.

Main Methods:

• Physician experts from 7 subspecialties utilized group consensus and multi-criteria decision analysis (1000Minds™).
• Developed a weighted index (pGTI) with 107 toxicity items across health domains (minor, moderate, major) and a Damage Checklist for less common toxicities.
• Validated the pGTI against expert clinical judgment, achieving excellent agreement (weighted kappa 0.86).

Main Results:

• The pGTI includes quantitative scores (Cumulative Worsening Score, Aggregate Improvement Score) and a qualitative Damage Checklist.
• A digital platform was developed for ease-of-use, incorporating algorithms for age/sex-related references and pediatric-specific growth considerations.
• The pGTI demonstrated excellent agreement with expert clinical judgment in ranking toxicity cases.

Conclusions:

• The developed pGTI is a validated, weighted, composite index for assessing GC-related morbidity in children and adolescents.
• The digital platform enhances the rigor, accuracy, and ease-of-use of toxicity assessment in clinical and research settings.
• The pGTI facilitates nuanced calculations crucial for precise GC toxicity monitoring in pediatric populations.
