Insights
Machine learning models accurately predict cerebral palsy (CP) risk by analyzing factors like low birth weight and premature birth. Early identification of synergistic risk factors enables targeted interventions for high-risk newborns.
Area of Science:
- Pediatric Neurology
- Machine Learning in Healthcare
- Neonatal Risk Assessment
Background:
- Cerebral palsy (CP) poses a significant challenge in pediatric neurology.
- Early identification of CP risk factors is crucial for timely intervention.
- Existing screening methods may not fully capture synergistic effects of multiple risk factors.
Purpose of the Study:
- To develop and evaluate machine learning (ML) models for early cerebral palsy (CP) prediction.
- To identify synergistic perinatal risk factors for CP in a pediatric population.
- To stratify CP risk based on combined exposure to key factors.
Main Methods:
- Retrospective case-control study utilizing demographic, perinatal, and clinical data.
- Development and evaluation of four ML models: Random Forest, XGBoost, SVM, and FFN.
- Performance assessment using AUC, precision, recall, F1-score, and SHAP interpretability.
- Analysis of cumulative risk across subgroups using a multidimensional interaction framework.
Main Results:
- ML models demonstrated high predictive accuracy (ROC-AUC: 0.98-0.99).
- Key predictors identified: low birth weight (LBW), premature birth, NICU admission, and multiple pregnancies.
- Infants with all four factors showed a 93.15% CP incidence, indicating significant synergistic risk.
- A dose-response gradient was observed, with NICU admission and birth weight predicting higher GMFCS classification.
Conclusions:
- Four ML models achieved high predictive accuracy for CP risk stratification in a Middle Eastern cohort.
- LBW, very preterm birth, NICU admission, and multigravidity were consistent cross-model predictors.
- Synergistic interactions of these exposures necessitate a shift towards ML-driven neonatal surveillance.
- Findings support data-driven early risk stratification and targeted interventions for high-risk neonates.
Aim:
To develop and evaluate machine learning (ML) models for early cerebral palsy (CP) prediction and identify synergistic perinatal risk factors in a pediatric population.
Method:
We conducted a retrospective case-control study using demographic, perinatal, and postnatal clinical data collected at Sidra Medicine, Qatar. Four ML models- Random Forest (RF), XGBoost, Support Vector Machine (SVM), and a feedforward neural network (FFN) were trained using clinically relevant features. Model performance was assessed using precision, recall, area under the curve (AUC), F1-score, and SHAP-based interpretability. A multidimensional interaction framework was used to evaluate cumulative risk across 16 subgroups.
Results:
All ML models exhibited high predictive accuracy (ROC-AUC: 0.98-0.99, and PR-AUC: 0.97-0.98), with four key factors: low birth weight (LBW), premature birth, neonatal intensive care unit (NICU) admission, and multiple pregnancies. Infants exposed to all four factors demonstrated a 93.15% incidence of CP (OR = 1382.67; p < 0.0001). A clear dose-response gradient was observed across exposure subgroups. SHAP analysis confirmed consistent cross-model importance of LBW, very preterm birth, NICU admission, and multigravidity. Cross-validation confirmed model robustness, and severity analysis identified NICU admission and birth weight as independent predictors of higher GMFCS classification.
Conclusion:
Four ML models achieved high predictive accuracy (ROC-AUC 0.98-0.99) for CP risk stratification in a Middle Eastern pediatric cohort, with LBW, very preterm birth, NICU admission, and multigravidity as the most consistent cross-model predictors. The synergistic interaction of these exposures - evidenced by a 93.15% CP incidence in the highest-risk subgroup - supports a paradigm shift from single-factor screening to exposure-weighted, ML-driven neonatal surveillance. These findings provide a data-driven foundation for early risk stratification and targeted intervention planning in high-risk neonatal population.
