Acute Clinical Predictors of Symptom Recovery in Emergency Department Patients with Uncomplicated Mild Traumatic Brain Injury or Non-Traumatic Brain Injuries.

ABSTRACT: There is a subset of patients with mild traumatic brain injury (mTBI) who report persistent symptoms that impair their functioning and quality of life. Being able to predict which patients will experience prolonged symptom recovery would help clinicians target resources for clinical follow-up to those most in need, and would facilitate research to develop precision medicine treatments for mTBI. The purpose of this study was to investigate the predictors of symptom recovery in a prospective sample of emergency department trauma patients with either mTBI or non-mTBI injuries. Subjects were examined at several time points from within 72?h to 45 days post-injury. We quantified and compared the value of a variety of demographic, injury, and clinical assessment (symptom, neurocognitive) variables for predicting self-reported symptom duration in both mTBI (n?=?89) and trauma control (n?=?73) patients. Several injury-related and neuropsychological variables assessed acutely (< 72?h) post-injury predicted symptom duration, particularly loss of consciousness (mTBI group), acute somatic symptom burden (both groups), and acute reaction time (both groups), with reasonably good model fit when including all of these variables (area under the receiver operating characteristic curve [AUC]?=?0.76). Incorporating self-reported litigation involvement modestly increased prediction further (AUC?=?0.80). The results highlight the multifactorial nature of mTBI recovery, and injury recovery more generally, and the need to incorporate a variety of variables to achieve adequate prediction. Further research to improve this model and validate it in new and more diverse trauma samples will be useful to build a neurobiopsychosocial model of recovery that informs treatment development.

Project description:ObjectivesMild traumatic brain injury (mTBI) is the most common emergency department (ED) brain injury presentation worldwide. Despite its frequency, practice variation and care gaps exist among emergency physicians (EPs) in diagnosing and appropriately managing mTBI in the ED. The objective of this review was to identify mTBI-specific training undertaken to improve the detection and management of mTBIs by EPs and its impact on practice.MethodsA comprehensive search strategy utilized four bibliographic databases, the gray literature and the keywords concussion, mild traumatic brain injury, medical education, and continuing medical education (CME). To be included, studies were required to report on mTBI training received by practicing EPs at any point during their medical education or career. Studies examining clinical practice guidelines or use of diagnostic tools without active implementation or formal training were not included. Two reviewers screened unique citations for relevance and reviewed the full texts of relevant articles. Two independent researchers extracted data and assessed methodologic quality. At all stages, a third independent reviewer adjudicated discrepancies.ResultsOverall, five studies were included from 409 unique results. None of the included studies were of high quality. Identified training on mTBI consisted of three training toolkits, conference presentations and academic journal articles, and pediatric fellowship training. Training primarily occurred as CME and focused on awareness of and management of mTBI; three studies reported physician practice changes, including increases in the use of evidence-based return-to-school and return-to-activity recommendations.ConclusionsThe few studies identified addressing mTBI training targeting EPs demonstrate the limited attention given to this issue. The current evidence-to-practice gap in mTBI management places patients at risk for suboptimal care in the ED, and existing mTBI knowledge translation, including education, requires optimization to effectively address the current gap in evidence-based practice for mTBI diagnosis and management in the ED.
