Conditions

Outcome Measures

Primary Outcomes (1)

  • Consciousness level using the Glasgow Coma Scale (GCS) scale.

    The GCS score ranges from 15 to 3 points, with a higher score indicating an alert consciousness and a lower score indicating decreased consciousness. A binary outcome of GCS\<=8 and GCS\>8 will be used in this study.

    At the time of study completion (May 31, 2023, anticipated).

Secondary Outcomes (1)

  • Consciousness level using the AVPU (Alert; Verbal; Pain; Unresponsive) scale.

    At the time of study completion (May 31, 2023, anticipated).

Study Population

Adult patients with a decreased level of consciousness who have visited the study hospital EDs and have stayed at the ED for less than 12 hours at the time of enrollment will be included.

You may qualify if:

  • Adult ED patients with a decreased level of consciousness (verbal, pain, or unresponsive using the AVPU scale, and a GCS-E score of less than 4) who have stayed at the ED for less than 12 hours at the time of enrollment.

You may not qualify if:

  • Patients with the difficulty of applying EEG due to head trauma or skull deformities.
  • Patients for whom standard treatment may be significantly delayed by applying the EEG device.
  • Patients with a guardian who do not agree to enroll in this study.
