Insights
This study introduces a new deep neural network to predict neonatal morbidities, offering a data-driven definition of prematurity beyond gestational age. This machine learning approach improves upon traditional methods for assessing infant health risks.
Area of Science:
- Neonatal Medicine
- Artificial Intelligence
- Public Health
Background:
- Prematurity is a leading cause of neonatal mortality and long-term impairment.
- Current definitions of prematurity rely on gestational age or birthweight, which do not fully capture neonatal morbidity.
- A more comprehensive approach is needed to identify and manage risks associated with premature birth.
Purpose of the Study:
- To develop and validate a multi-task deep neural network model for predicting twelve neonatal morbidities.
- To establish a data-driven approach for defining prematurity based on predicted neonatal morbidities.
- To improve the assessment of prematurity and inform clinical decision-making.
Main Methods:
- Utilized a large dataset of 11,594,786 livebirths in California (1991-2012).
- Integrated maternal demographics, medical history, obstetrical complications, and prenatal fetal findings.
- Developed a multi-task deep neural network to simultaneously predict multiple neonatal morbidities.
Main Results:
- The proposed deep neural network model demonstrated superior performance compared to traditional gestational age and birthweight-based models.
- The model achieved a higher area under the precision-recall curve (0.326) than gestational age (0.229) and small for gestational age (0.156) models.
- Successfully predicted twelve distinct neonatal morbidities.
Conclusions:
- Machine learning techniques hold significant potential for predicting multiple prematurity phenotypes.
- This data-driven approach can enhance clinical decisions for preventing, diagnosing, and treating neonatal morbidities.
- A new, morbidity-focused definition of prematurity can be established using advanced predictive modeling.
Abstract:
Whereas prematurity is a major cause of neonatal mortality, morbidity, and lifelong impairment, the degree of prematurity is usually defined by the gestational age (GA) at delivery rather than by neonatal morbidity. Here we propose a multi-task deep neural network model that simultaneously predicts twelve neonatal morbidities, as the basis for a new data-driven approach to define prematurity. Maternal demographics, medical history, obstetrical complications, and prenatal fetal findings were obtained from linked birth certificates and maternal/infant hospitalization records for 11,594,786 livebirths in California from 1991 to 2012. Overall, our model outperformed traditional models to assess prematurity which are based on GA and/or birthweight (area under the precision-recall curve was 0.326 for our model, 0.229 for GA, and 0.156 for small for GA). These findings highlight the potential of using machine learning techniques to predict multiple prematurity phenotypes and inform clinical decisions to prevent, diagnose and treat neonatal morbidities.
