Evaluation of automated pediatric sleep stage classification using U-Sleep: a convolutional neural network.
J Clin Sleep Med
September 2024
The University of Queensland, St Lucia, Brisbane, Queensland, Australia.
Article Synopsis
- - U-Sleep, an automated sleep stager, was tested for accuracy against trained human scorers using a dataset of 50 pediatric polysomnograms and a larger clinical dataset of 3114 polysomnograms to see if it can effectively replace human analysis.
- - The study found that U-Sleep's performance was statistically equivalent to human scorers with a kappa statistic of 0.79 compared to 0.78 for humans, indicating it was reliable for sleep staging in children.
- - However, U-Sleep's accuracy decreased in children under 2 years and those with sleep-related health issues, suggesting it can be utilized clinically for pediatric patients, but caution is needed for specific subgroups.
