Trial Outcomes & Findings for Evaluation of VA's Traumatic Brain Injury (TBI) Clinical Reminder and Comprehensive TBI Evaluation (CTBIE) (NCT NCT00852527)

NCT ID: NCT00852527

Last Updated: 2015-04-28

Results Overview

Patients were initially assessed with the TBI Clinical Screen at their local VA. To assess the diagnostic accuracy of the TCRS, a dual-criterion approach was used. The VA Comprehensive TBI Evaluation (CTBIE), a secondary evaluation, served as the first criterion and the Structured TBI Diagnostic Interview (STDI) as the second criterion.

PRIMARY outcome

Timeframe: All OEF/OIF Veterans to receive TCRS upon enrollment in VA

Population: Although 456 participants were consented and enrolled in the study, data for 13 participants had missing assessment data and another 5 were determined to have moderate TBI resulting in 438 cases for the analysis.

Patients were initially assessed with the TBI Clinical Screen at their local VA. To assess the diagnostic accuracy of the TCRS, a dual-criterion approach was used. The VA Comprehensive TBI Evaluation (CTBIE), a secondary evaluation, served as the first criterion and the Structured TBI Diagnostic Interview (STDI) as the second criterion.
