COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Enrolled in-patients in the Alfred Epilepsy Diagnostic Unit will be asked to wear the eMotion Faros Sensor during the monitoring period, which is a Class IIa medical device that records electrocardiogram (ECG).
It involves the participant wearing 3x5-cent sized sticky electrodes on chest for 24-hours, repeated for each of the 5 days they are in the clinic. with the ECG recorder attached to one of the electrodes.
The device will be administered by the Alfred research assistant assigned to the project.
After the 5 days of this data has been recorded, the Faros sensor/recorder is removed and the 5 days of ECG recordings downloaded.
The TRIO software will then be used to post-process these 5-day recordings and TRIO seizure scoring files generated for later comparison with the independent Alfred Hospital clinical seizure scoring of this same data.

Diagnosis / Prognosis
Comparator / control treatment
There is currently no device on the market that accurately automatically detects epileptic seizures, especially those that are non-convulsive ('absence seizures').
The gold standard throughout the world for seizure diagnosis is manual post-processing of video-EEG monitoring recordings, which will be the comparator in this study.

The video-EEG patient data is collected by setting up continuous recording of 16 channels of EEG from a patient skull cap, and of a continuos video of the patient, for the 5 days the patients are in the clinic.

In this current video-EEG seizure scoring procedure, after the data has been recorded a highly trained clinical specialist scrolls through simultaneous displays of the patient video and 16 channels of EEG to decide when seizures have occurred. This procedure typically takes ~8 hours to score 4-5 days of patient video-EEG data.

The TRIO software analysis of the FAROS 5 days of ECG recording is similarly post-processed at the end of the 5 days.
Control group

Primary outcome [1] 323594 0
Seizure events as assessed by high-resolution ECG recordings with the “TRIO” software and with Alfred Video-EEG to be compared to provide false positive / false negative assessment of TRIO performance versus the current clinical standard.
Timepoint [1] 323594 0
Data will be collected during the five-day inpatient video-EEG monitoring period.
Secondary outcome [1] 382694 0
The quality of ECG recordings from the compact 2-channel chest-mounted sensor for seizure detection, assessed by sufficient performance of the "TRIO" software.
Timepoint [1] 382694 0
Data will be collected during the five-day inpatient video-EEG monitoring period.

Type of endpoint(s)
Statistical methods / analysis
The TRIO software processes blinded 5-day ECG recordings and provides a list of ’events’ with their start time, end time, duration, and the maximum value of the TRIO index of cardiac disorder (ICD). This TRIO ‘events’ list is then sent to The Alfred Epilepsy Clinic where the TRIO events are compared with their Video-EEG scoring of seizures for the same patient. The false positive and false negative rates for the TRIO scoring are then calculated.

Brief summary
This is a single-centre, prospective post-market study using a TGA approved Class IIa medical device (“eMotion Faros Sensor”), which records electrocardiogram (ECG) through Kaoskey’s prototyped developed software suite (“TRIO”). Adult (18 years or older) participants admitted for inpatient video-EEG monitoring at The Alfred Hospital meeting eligibility criteria will be invited to participate in the study. Enrolled participants will be asked to wear the eMotion Faros Sensor during the monitoring period. High-resolution ECG recordings will be recorded during the patient’s admission and assessed using the TRIO software suite.
