Effect of reducing the recording time of standard EEGs on the detection of EEG-abnormalities in the management of the epilepsies of childhood

We conclude that reducing the recording time of standard EEGs to 15 min may miss abnormalities in 2.36% [95% CI: 0.63-4.09%] overall and 6.42% [95% CI: 2.2-11.8%] of those with an abnormality supportive of an epilepsy to explain the reported symptoms. This result should inform any future discussions on seeking resource-efficiencies.
