Development of the ACRM Structured TBI Interview and Application of the ACRM Diagnostic Criteria in Research 1213

In 2023, the ACRM Brain Injury Special Interest Group, Mild TBI Task Force published updated diagnostic criteria for mild traumatic brain injury (mTBI) following a rigorous evidence review and expert consensus process. A key goal of this effort was to enhance the quality and consistency of mTBI research by establishing unified diagnostic criteria applicable across diverse settings, including civilian, military, and sports-related. This symposium will showcase three initiatives relevant to the application of the ACRM mTBI criteria that have advanced diagnostic precision in different contexts.First, Dr. Lange and Gillow will outline the work of the ACRM mTBI Task Force in developing a standardized structured diagnostic interview to address the ACRM diagnostic criteria for mild TBI. Second, Dr. Manley will discuss the successes, challenges, and pitfalls of applying the ACRM criteria in an acute care setting that is currently being implemented in the TRACK-TBI study. Third, Dr. Nelson will present a post-hoc application of the criteria to confirm mTBI caseness in a research dataset, demonstrating the feasibility and implications of retrospective classification. Collectively, these efforts highlight the potential of the ACRM diagnostic criteria to improve case ascertainment and methodological rigor in mTBI research.
