A natural language processing algorithm to extract characteristics of subdural hematoma from head CT reports.
Researchers created a natural language processing (NLP) algorithm to predict radiographic characteristics of subdural hematomas (SDH). The NLP was used to extract data from cranial computed tomography (CT) scan reports for patients with SDH. The results were measured for accuracy compared to cranial CT scan interpretations by board-certified attending radiologists and data coded by two ED physicians.. Output performance was considered high, with an algorithm accuracy of 0.84 for side of largest SDH, 0.88 for thickness of largest SDH, and 0.92 for size of midline shift.

Perception of barriers to the diagnosis and receipt of treatment for neuropsychiatric disturbances after traumatic brain injury.
This study explored perceptions of barriers and facilitators to the diagnosis and receipt of treatment for neuropsychiatric disturbances (NPDs) after traumatic brain injury (TBI). Using semistructured interviews and focus groups, it found that barriers included poor provider education on TBI NPDs and limited access to care due to lack of insurance, transportation, and income. Facilitators included patient education on TBI NPDs and strong caregiver support.

Simulation and the diagnostic process: a pilot study of trauma and rapid response teams.
Simulation can be used to recreate conditions that engage teams in the diagnostic process. In contrast to most instruction about diagnostic error, teams learn through realistic experiences and receive timely feedback about their decision-making skills. The purpose of this study was to assess how trauma teams (TrT) and pediatric rapid response teams (RRT) managed scenarios that included a diagnostic error.

Postconcussion symptoms reported by Operation Enduring Freedom/Operation Iraqi Freedom veterans with and without blast exposure, mild traumatic brain injury, and posttraumatic stress disorder.
This study examined symptom reporting related to the 10th Edition of the International Statistical Classification of Diseases (ICD-10) criteria for postconcussional syndrome (PCS) in veterans. One aim was to examine relationships among PCS symptoms by using the British Columbia Postconcussion Symptom Inventory (BC-PSI). BC-PSI factors were interpreted as cognitive, vestibular, affective, anger, and somatic. Items and factor scores were highest for veterans with blast exposure plus mTBI, and lowest for controls.

Will neuroimaging reveal a severe intracranial injury in this adult with minor head trauma?: The rational clinical examination systematic review.
The study objective was to assess systematically the accuracy of symptoms and signs in adults with minor head trauma in order to identify those with severe intracranial injuries. It found that combinations of history and physical examination features in clinical decision rules can identify patients with minor head trauma at low risk of severe intracranial injuries.

Motor vehicle crash severity estimations by physicians and prehospital personnel.
The purpose of this study was to determine whether emergency physicians (EPs) and EMS personnel differ in their assessment of motor vehicle collision severity and the potential for serious injury when viewing crash scene photographs. They found excellent crash and injury agreement at both ends of the severity spectrum but only modest agreement, and therefore greater variability, in the middle of the severity spectrum.
