Insights
This study developed a multimodal model using early physiological signals to predict 2-year outcomes in preterm infants. The model accurately forecasts neurodevelopmental delays and mortality risk in vulnerable newborns.
Area of Science:
- Neonatal Medicine
- Developmental Neuroscience
- Biomedical Engineering
Background:
- Preterm infants face significant risks for adverse long-term outcomes.
- Early identification of high-risk infants is crucial for timely intervention.
- Predictive models can improve neurodevelopmental outcomes in this population.
Purpose of the Study:
- To develop and validate a multimodal predictive model for 2-year outcomes in preterm infants.
- To integrate physiological signals from the initial days of life into a predictive framework.
- To assess the model's performance against established clinical risk scores.
Main Methods:
- Simultaneous multi-channel electroencephalography (EEG), SpO2, and heart rate (HR) monitoring were used in infants <32 weeks gestation.
- EEG grades were combined with gestational age (GA) and quantitative HR/SpO2 features in a logistic regression model.
- Bayley Scales of Infant Development-III assessed 2-year neurodevelopmental outcomes; a clinical course score was used for comparison.
Main Results:
- The multimodal model achieved an AUC of 0.83 for predicting 2-year outcomes.
- Model performance was comparable to the clinical course score (AUC 0.79).
- The model demonstrated the ability to predict outcomes days after birth.
Conclusions:
- Quantitative analysis of physiological signals, GA, and graded EEG shows promise for predicting outcomes.
- This approach can identify infants at risk of mortality or delayed neurodevelopment at 2 years.
- Early predictive modeling can guide clinical management for preterm infants.
Background:
Preterm infants are at risk of adverse outcome. The aim of this study is to develop a multimodal model, including physiological signals from the first days of life, to predict 2-y outcome in preterm infants.
Methods:
Infants <32 wk gestation had simultaneous multi-channel electroencephalography (EEG), peripheral oxygen saturation (SpO2), and heart rate (HR) monitoring. EEG grades were combined with gestational age (GA) and quantitative features of HR and SpO2 in a logistic regression model to predict outcome. Bayley Scales of Infant Development-III assessed 2-y neurodevelopmental outcome. A clinical course score, grading infants at discharge as high or low morbidity risk, was used to compare performance with the model.
Results:
Forty-three infants were included: 27 had good outcomes, 16 had poor outcomes or died. While performance of the model was similar to the clinical course score graded at discharge, with an area under the receiver operator characteristic (AUC) of 0.83 (95% confidence intervals (CI): 0.69-0.95) vs. 0.79 (0.66-0.90) (P = 0.633), the model was able to predict 2-y outcome days after birth.
Conclusion:
Quantitative analysis of physiological signals, combined with GA and graded EEG, shows potential for predicting mortality or delayed neurodevelopment at 2 y of age.
