    "subtitle": null,
    "abstract": "Existing work has attributed the low clinical utility of continuous CTG to the reliability and accuracy of Cardiotocography judgments. The aim was to determine whether aggregating the judgments of multiple obstetricians (leveraging the \"wisdom of crowds'') using obstetricians' optimized estimates of the probability of hypoxia improves accuracy. In the current study, we apply three different aggregation techniques to the evaluations of nine obstetricians from the CTU-CHB Intrapartum Cardiotocography Database. The evaluations were optimized estimates of the probability of hypoxia in each evaluation category. The three aggregation models ranged in complexity from an unweighted aggregation scheme to an approach that weighted evaluations based on the contribution of the obstetricians. All the aggregation models were shown to improve judgment accuracy above chance performance.  However, the most accurate model was the one which calculated the simple average of obstetricians' judgments. There was no additional benefit of selecting obstetricians who were positive contributors to an ensemble and weighing the evaluations based on their contribution to the ensemble. Aggregating obstetricians' evaluations may be a solution to the ongoing reliability and accuracy issues in fetal heart rate judgment.",
