Emergency Department (ED) visits for mild Traumatic Head Injury (mTBI) have greatly increased due to more awareness of potential consequences of such injuries. While the vast majority (>80%) of mTBI patients who go to the ED receive a head CT scan, >90% of them are found to be negative. This practice unnecessarily exposes these patients to radiation, increases the use of ED resources, and lengthens throughput times. The integration of reliable, objective predictors of intracranial injury for making important initial assessment decisions can impact significantly on this practice.

White Paper Info

Within one rapid EEG test at the point of care, BrainScope provides objective data on both brain bleeds and concussions to assist healthcare providers in evaluating head injured patients. This study was successful in determining utilization, staff assessment, and patient experience of the BrainScope technology in daily use. The results of the trial were overwhelmingly positive.

A patient with mild traumatic brain injury is a person who has had a traumatically induced physiological disruption of brain function, as manifested by at least one of the following:

1. Any period of loss of consciousness;

2. Any loss of memory for events immediately before or after the accident;

3. Any alteration in mental state at the time of the accident (e.g., feeling dazed, disoriented, or confused); and

4. Focal neurological deficit(s) that may or may not be transient; but where the severity of the injury does not exceed the following: loss of consciousness of approximately 30 minutes or less; after 30 minutes, an initial Glasgow Coma Scale (GCS) of 13–15; and post traumatic amnesia (PTA) not greater than 24 hours.

This definition includes:

1. The head being struck,

2. The head striking an object, and

3. The brain undergoing an acceleration/deceleration movement (i.e., whiplash) without direct external trauma to the head.
