title: I-CARE: International Cardiac Arrest REsearch consortium electroencephalography database - Brain Continuity Index

description: The International Cardiac Arrest REsearch consortium (I-CARE) database
 includes baseline clinical information and continuous
 electroencephalography (EEG) recordings from 1,020 comatose patients with
 a diagnosis of cardiac arrest who were admitted to an intensive care unit
 from seven academic hospitals in the U.S. and Europe. Patients were
 monitored with 18 bipolar EEG channels over hours to days for the
 diagnosis of seizures and for neurological prognostication. Long-term
 neurological function was determined using the Cerebral Performance
 Category scale.

The BCI value ranges from zero (fully suppressed) to 1 (continuous).  The icare_BCI file is screenshot representing the number of rows in the .mat file. There are 3,440 rows corresponding to the 1,020 subjects and all the individual files. The first column has the subject ID and the file number (consecutive). The second column indicates the time elapsed since the time of return of spontaneous circulation. The third column includes the BCI values, which is organized in consecutive 10 seconds chunks. ## Access information Other publicly accessible locations of the data: * [https://bdsp.io/content/bdsp-icare/1.0/](https://bdsp.io/content/bdsp-icare/1.0/) Data was derived from the following sources: * The database originates from seven academic hospitals in the U.S. and Europe led by investigators part of the International Cardiac Arrest REsearch consortium (I-CARE). 1.
