Evaluating the Feasibility of Utilizing a Novel Brain Activity Monitor in the Neurosciences Intensive Care Unit

In the study population of sedated, intubated critically ill patients, the research team hypothesize the following:

• Neurosteer's derived signals and parameters will be correlated to and will have at least fair agreement with the Richmond Agitation Sedation Scale (RASS) for measuring depth of sedation.
• Neurosteer's derived signals and parameters will be correlated to and have at least fair agreement with the Confusion Assessment Method (CAM-ICU) to screen for and diagnose delirium.
• For enrolled patients undergoing cEEG monitoring as standard of care, the detection of burst suppression, seizures, and ictal-interictal continuum between Neurosteer's derived signals and parameters and continuous EEG monitoring readings will be correlated and have at least fair agreement.
• There will be no significant difference in the correlations determined in our primary objective between NSICU patients with and without ANI.

The research team will be conducting a single-site study to evaluate these hypotheses. The research team will enroll 100 patients admitted to the NSICU. 50 of these patients will have an ANI and the other 50 will not have an ANI. The research team will define ANI as subjects having Acute Ischemic Stroke (AIS), Intracerebral Hemorrhage, Subarachnoid Hemorrhage (SAH), Status Epileptics, Traumatic Brain Injury (TBI), Brain Tumors, Meningitis/encephalitis, post cardiac arrest hypoxic ischemic encephalopathy. The research team will define subject without ANI to have neuromuscular disorders such as myasthenia gravis, spine surgery, septic shock, acute respiratory distress syndrome, and Hemorrhagic shock ex. from gastrointestinal bleeding. The research team will obtain written informed consent from all patients and/or their Legally Authorized Representative (LAR) to conduct the study. All enrolled patients will receive the intervention, the Neurosteer brain monitoring platform. Intra-individual comparisons will be made between standard of care assessments and the findings of the Neurosteer device. Inter-individual comparisons between patients with and without ANI will also be made. Statistical analyses will be conducted halfway through study enrollment and upon completion of enrollment and data entry. The study intervention will span the duration of the patient's admission in the NSICU. Patients will be screened for consented and screened for eligibility as they get admitted to the NSICU.
