Predicting polysomnographic severity thresholds in children using machine learning.

We provide proof of principle for the utility of machine learning, oximetry, and actigraphy to screen for severe obstructive sleep apnea syndrome (OSAS) in children. Clinical parameters perform poorly in predicting the severity of OSAS, which is confirmed in the current study. The predictive accuracy for severe OSAS was improved by a smaller subset of quantifiable physiologic parameters, such as oximetry. The results of this study support a lower cost, patient-friendly screening pathway to identify children in need of in-hospital observation after surgery.
