Technical Proof Study Prolira Deltascan

Demonstrates that the relative deltapower from a one minute artefact free EEG recording, with only two electrodes in a frontal-parietal derivation can distinguish among patients who have delirium and those who do not.

Validation Study EEG Acute Encephalopathy

Demonstrates that automated polymorphic delta activity detection in 1-channel EEG [ed.: DeltaScan algorithm] has a diagnostic performance for acute encephalopathy >85% (AUROC=0.86, CI = [0.81–0.90]).

Clearance Study EEG Acute Encephalopathy DeltaScan

Demonstrates the diagnostic performance of DeltaScan is >85% for acute encephalopathy (AUROC=0.855, CI = [0.82, 0.89]) on ICUs and ward patients. The majority of data is from patients 60 years or older.

Further clinical detection benefits

Time-to-Detection

The first validation study provided multiple measurements per patient over three consecutive postoperative days. Analysis of this data shows a detection benefit of 1-1.5 days for DeltaScan over usual care.

Making the invisible visible

In each study, it was found that often cases of AE do not coincide with clinical signs of delirium. EEG experts as well as DeltaScan find brain dysfunction (polymorphic delta activity) which is a prompt for further clinical workup.
