Article Abstract
Objective: To examine whether post-9/11 veterans who screened positive for mild traumatic brain injury (mTBI) but did not complete a Comprehensive TBI Evaluation (CTBIE) were at higher risk of subsequent adverse events compared with veterans who screened positive and completed a CTBIE. Upon CTBIE completion, information assessed by a trained TBI clinician indicates whether there is mTBI history (mTBI+) or not (mTBI-).
Setting: Veterans Health Administration (VHA) outpatient services.
Participants: A total of 52 700 post-9/11 veterans who screened positive for TBI were included. The follow-up review period was between fiscal years 2008 and 2019. The 3 groups studied based on CTBIE completion and mTBI status were: (1) mTBI+ (48.6%), (2) mTBI- (17.8%), and (3) no CTBIE (33.7%).
Design: This was a retrospective cohort study. Log binomial and Poisson regression models adjusting for demographic, military, pre-TBI screening health, and VHA covariates examined risk ratios of incident outcomes based on CTBIE completion and mTBI status.
Main Measures: Incident substance use disorders (SUDs), alcohol use disorder (AUD), opioid use disorder (OUD), overdose, and homelessness documented in VHA administrative records, and mortality as documented in the National Death Index, 3 years post-TBI screen. VHA outpatient utilization was also examined.
Results: Compared with the no CTBIE group, the mTBI+ group had 1.28 to 1.31 times the risk of incident SUD, AUD, and overdose, but 0.73 times the risk of death 3 years following TBI screening. The mTBI- group had 0.70 times the risk of OUD compared with the no CTBIE group within the same period. The no CTBIE group also had the lowest VHA utilization.
Conclusions: There were mixed findings on risk of adverse events for the no CTBIE group relative to the mTBI+ and mTBI- groups. Future research is needed to explore the observed differences, including health conditions and healthcare utilization, documented outside VHA among veterans who screen positive for TBI.

Objective: Those who served on active duty after September 11, 2001 (Post-9/11) are screened for deployment-related mild traumatic brain injury (mTBI) when initiating Veterans Health Administration (VHA) clinical services. Positive screeners are offered a referral to a Comprehensive TBI Evaluation (CTBIE) by a TBI specialist to further determine deployment-related mTBI history and access interdisciplinary care if indicated. This study examined whether Post-9/11 veterans who screened positive and also participated in a prospective longitudinal study (PLS) differed in characteristics and outcomes depending on their clinical VHA CTBIE completion status and mTBI positive (+) or negative (-) determinations (CTBIE = mTBI+, CTBIE = mTBI-, No CTBIE).

Objective: To examine the relationship between neighborhood disadvantage and severity of vestibular, sensory, mood-behavioral, and cognitive neurobehavioral symptoms among Veterans with a mild traumatic brain injury (mTBI); and whether Veterans in underrepresented racial/ethnic groups with high neighborhood disadvantage experience the most severe symptoms.
Setting: Outpatient Veterans Health Administration (VHA).
Participants: Veterans with the following data available in the electronic health record (2014-2020): (1) clinician-confirmed mTBI and complete neurobehavioral symptom inventory (NSI) as part of their comprehensive traumatic brain injury evaluation (CTBIE) and (2) area deprivation index (ADI) scores assessing neighborhood disadvantage from the same quarter as their CTBIE.

Purpose: To examine clinical outcomes and employment status in Veterans with and without a dual diagnosis of traumatic brain injury (TBI) and spinal cord injury (SCI).
Methods: This cross-sectional study examined a national sample of Veterans enrolled in the VA Million Veteran Program who completed the Comprehensive TBI Evaluation (CTBIE) as part of the Veterans Health Administration's TBI Screening and Evaluation Program. Veterans (N = 12,985) were classified into the following TBI/SCI groups using CTBIE data: those with a dual diagnosis of TBI and SCI (TBI+/SCI+); those with a history of TBI but no SCI (TBI+/SCI-); and those with no history of TBI or SCI (TBI-/SCI-; i.

Article Synopsis
- - The study aimed to evaluate if post-9/11 veterans who screened positive for mild traumatic brain injury (mTBI) but didn't complete a Comprehensive TBI Evaluation (CTBIE) faced higher risks of negative outcomes compared to those who did complete it.
- - Researchers analyzed data from over 52,000 veterans between 2008-2019, categorizing them into three groups based on CTBIE completion and mTBI status: mTBI+, mTBI-, and no CTBIE.
- - Results indicated that the mTBI+ group had a higher risk of substance use disorders and overdose compared to the no CTBIE group, but lower mortality rates; further exploration is needed to understand
