To evaluate the ability of NICU (NeuroIntensive Care Unit) staff to interpret, before and after a training period, symmetry, sedation level, seizures activities and artefact on continuous cEEG/qEEG (continuous electroencephalography/quantitative electroencephalography) tracings.

Using a web based tool, the clinicians of the two study centers will review 24 hours of recording (raw EEG data + derived qEEG variables).

The intensivists will evaluate:

• simmetry,
• sedation level,
• seizures activities and
• artefact on continuous cEEG/qEEG tracings. The same tracings will be blindly reviewed by a certified neurophysiologist (using the app). The neurophysiologist evaluation will be considered as "reference".

The results of the evaluation will be compared (intensivists vs. neurophysiologist) in order to understand if the intensivists are able to adequately identify the pathological findings.

The study period will be:

• before a formal training
• after a formal training by neurophysiologist in order to understand if the training is able to improve the intensivists performance.

Inclusion Criteria:

Intensivists wil evaluate daily qEEG recordings of:

• Patients in coma after a traumatic/vascular event
• Admitted to neurointensive care and
• Recorded with continuous EEG for clinical reasons

Exclusion Criteria:

• No EEG recording > 24 hours

Intensivists will evaluate tracing from patients in coma after a traumatic/vascular event admitted to neurointensive care and recorded with continuous EEG for clinical reasons

All-Cause Mortality, Serious, and Other (Not Including Serious) Adverse Events were not monitored/assessed
