AI-POWERED NEONATAL SEPSIS PREDICTION
Revolutionizing Early Diagnosis with AI: Identifying Key Attributes and Predicting Neonatal Sepsis
This study demonstrates the effectiveness of artificial intelligence models in identifying critical risk factors and predicting neonatal sepsis, offering a new frontier in pediatric healthcare.
This study evaluates the performance of artificial intelligence models in predicting neonatal sepsis and identifies the most influential attributes. Using real data from Pernambuco, Brazil, six machine learning models (AdaBoost, CatBoost, Gradient Boosting, LightGBM, Random Forest, XGBoost) were evaluated across three experiments based on different attribute selection criteria. The models achieved performance metrics ranging from 0.7213 to 0.8548, with AdaBoost and LightGBM showing the best results. SHAP analysis highlighted critical clinical attributes such as mechanical ventilation, intracranial hemorrhage, prematurity, CPAP use, TTN presence, and epicutaneous access as highly associated with sepsis cases. The research emphasizes the promising role of AI in early diagnosis and intervention strategies for neonatal sepsis in resource-limited settings.

Mechanical Ventilation & Sepsis Risk
Key Finding: Neonates on mechanical ventilation showed a significantly higher incidence of sepsis (69.61%) compared to those not ventilated (11.59%).
Explanation: Mechanical ventilation, while often necessary for critically ill neonates, is an invasive procedure that disrupts natural defense barriers, increasing susceptibility to hospital-acquired infections and systemic sepsis. This aligns with SHAP analysis identifying it as a highly influential attribute.
Enterprise Relevance: This highlights the critical importance of stringent infection control protocols and continuous monitoring for ventilated neonates. AI models can help prioritize surveillance for this high-risk group.
