Insights

Machine learning accurately identifies high-risk fetuses using cardiotocograph (CTG) data. The XGBoost model shows high precision in predicting pathological fetal states, aiding early intervention for better infant outcomes.

Area of Science:

  • Perinatal medicine
  • Medical informatics
  • Machine learning in healthcare

Background:

  • Intrapartum complications are a leading cause of perinatal mortality.
  • Fetal cardiotocograph (CTG) monitoring identifies high-risk pregnancies during labor.
  • Under-five mortality is significantly impacted by neonatal deaths.

Purpose of the Study:

  • To evaluate the precision of machine learning algorithms using CTG data.
  • To identify high-risk fetuses with adverse outcomes.
  • To improve early detection of fetal distress.

Main Methods:

  • Trained ten machine learning models on CTG data from 2126 women.
  • Utilized XGBoost, decision tree, and random forest algorithms.
  • Assessed model performance using sensitivity, precision, F1 score, and accuracy.

Main Results:

  • XGBoost, decision tree, and random forest models achieved >96% precision on training data.
  • The XGBoost model demonstrated the highest precision (>92%) for pathological fetal states on testing data.
  • Obstetrician interpretation served as the gold standard for fetal states (70% normal, 20% suspect, 10% pathological).

Conclusions:

  • The XGBoost model offers high prediction accuracy for adverse fetal outcomes.
  • This model can assist lay healthcare workers in low-resource settings for early triage and referral.
  • Improved identification of high-risk fetuses can reduce neonatal mortality.
