Feasibility and acceptability for LION, a fully remote, randomized clinical trial within the VA for light therapy to improve sleep in Veterans with and without TBI: An MTBI2 sponsored protocol: LION: A remote RCT protocol within VA.

Sleep-wake disturbances frequently present in Veterans with mild traumatic brain injury (mTBI). These TBI-related sleep impairments confer significant burden and commonly exacerbate other functional impairments. Therapies to improve sleep following mTBI are limited and studies in Veterans are even more scarce. In our previous pilot work, morning bright light therapy (MBLT) was found to be a feasible behavioral sleep intervention in Veterans with a history of mTBI; however, this was single-arm, open-label, and non-randomized, and therefore was not intended to establish efficacy. The present study, LION (light vs ion therapy) extends this preliminary work as a fully powered, sham-controlled, participant-masked randomized controlled trial (NCT03968874), implemented as fully remote within the VA (target n=120 complete). Randomization at 2:1 allocation ratio to: 1) active: MBLT (n=80), and 2) sham: deactivated negative ion generator (n=40); each with identical engagement parameters (60-min duration; within 2-hrs of waking; daily over 28-day duration). Participant masking via deception balanced expectancy assumptions across arms. Outcome measures were assessed following a 14-day baseline (pre-intervention), following 28-days of device engagement (post-intervention), and 28-days after the post-intervention assessment (follow-up). Primary outcomes were sleep measures, including continuous wrist-based actigraphy, self-report, and daily sleep dairy entries. Secondary/exploratory outcomes included cognition, mood, quality of life, circadian rhythm via dim light melatonin onset, and biofluid-based biomarkers. Participant drop out occurred in <10% of those enrolled, incomplete/missing data was present in <15% of key outcome variables, and overall fidelity adherence to the intervention was >85%, collectively establishing feasibility and acceptability for MBLT in Veterans with mTBI.

Associations Between Traumatic Brain Injury and Severity of Tinnitus-Related Functional Impairment Among US Military Veterans: A National, Population-Based Study.

OBJECTIVE: To describe associations between a history of traumatic brain injury (TBI) and the severity of tinnitus-related functional impairment among a national, stratified random sample of veterans diagnosed with tinnitus by the Department of Veterans Affairs (VA) healthcare system. SETTING: A multimodal (mailed and internet) survey administered in 2018. Participants: VA healthcare-using veterans diagnosed with tinnitus; veterans with comorbid TBI diagnosis were oversampled. DESIGN: A population-based survey. MAIN MEASURES: TBI history was assessed using International Classification of Diseases (ICD) diagnosis codes in veterans' VA electronic health records. The severity of participants' overall tinnitus-related functional impairment was measured using the Tinnitus Functional Index. Population prevalence and 95% confidence intervals (CIs) were estimated using inverse probability weights accounting for sample stratification and survey nonresponse. Veterans' relative risk ratios of very severe or moderate/severe tinnitus-related functional impairment, versus none/mild impairment, were estimated by TBI history using bivariable and multivariable multinomial logistic regression. RESULTS: The population prevalence of TBI was 5.6% (95% CI: 4.8-6.4) among veterans diagnosed with tinnitus. Veterans with a TBI diagnosis, compared with those without a TBI diagnosis, had 3.6 times greater likelihood of rating their tinnitus-related impairment as very severe (95% CI: 2.1-6.3), and 1.5 times greater likelihood of rating their impairment as moderate/severe (95% CI: 1.0-2.4), versus none/mild. CONCLUSIONS: These findings suggest an important role of TBI in the severity of tinnitus-related functional impairment among veterans. This knowledge can help inform the integration of tinnitus management services into the care received by veterans with TBI.

Prevalence and Correlates of VA-Purchased Community Care Use Among Post-9/11-Era Veterans With Traumatic Brain Injury.

OBJECTIVE: Post-9/11-era veterans with traumatic brain injury (TBI) have greater health-related complexity than veterans overall, and may require coordinated care from TBI specialists such as those within the Department of Veterans Affairs (VA) healthcare system. With passage of the Choice and MISSION Acts, more veterans are using VA-purchased care delivered by community providers who may lack TBI training. We explored prevalence and correlates of VA-purchased care use among post-9/11 veterans with TBI. SETTING: Nationwide VA-purchased care from 2016 through 2019. PARTICIPANTS: Post-9/11-era veterans with clinician-confirmed TBI based on VA's Comprehensive TBI Evaluation (N = 65 144). DESIGN: This was a retrospective, observational study. MAIN MEASURES: Proportions of veterans who used VA-purchased care and both VA-purchased and VA-delivered outpatient care, overall and by study year. We employed multivariable logistic regression to assess associations between veterans' sociodemographic, military history, and clinical characteristics and their likelihood of using VA-purchased care from 2016 through 2019. RESULTS: Overall, 51% of veterans with TBI used VA-purchased care during the study period. Nearly all who used VA-purchased care (99%) also used VA-delivered outpatient care. Veterans' sociodemographic, military, and clinical characteristics were associated with their likelihood of using VA-purchased care. Notably, in adjusted analyses, veterans with moderate/severe TBI (vs mild), those with higher health risk scores, and those diagnosed with posttraumatic stress disorder, depression, anxiety, substance use disorders, or pain-related conditions had increased odds of using VA-purchased care. Additionally, those flagged as high risk for suicide also had higher odds of VA-purchased care use. CONCLUSIONS: Veterans with TBI with greater health-related complexity were more likely to use VA-purchased care than their less complex counterparts. The risks of potential care fragmentation across providers versus the benefits of increased access to care are unknown. Research is needed to examine health and functional outcomes among these veterans.

Harmonizing federal interagency traumatic brain injury research data to examine depression and suicide-related outcomes.

OBJECTIVE: This proof-of-concept study was conducted to establish the feasibility of compiling Federal Interagency Traumatic Brain Injury Research (FITBIR) data pertaining to depression and suicide risk, with the secondary goal of improving understanding regarding these outcomes. FITBIR is a national repository of participant-level traumatic brain injury (TBI) data designed to address methodological limitations (e.g., small sample size, heterogeneity of injuries). METHOD: FITBIR studies with TBI severity and measures related to depression and suicidal ideation were identified. Data were harmonized across relevant studies and grouped to identify "probable depression" and suicidal ideation, resulting in a large, combined sample. Rates of probable depression and suicidal ideation were described across the available studies, considering the influence of demographic and/or injury-related factors on outcomes. RESULTS: Cross-sectional studies meeting criteria included four studies with depression outcomes and two with suicidal ideation outcomes. Two studies reported data appropriate for comparative analyses on depression. Combined results suggested that approximately 71% of participants were categorized as having probable depression. Participants with a history of mild TBI had 2.54 greater odds of probable depression (95% confidence interval [1.93, 3.34]) than those without a history of TBI. CONCLUSIONS: Methods, harmonization code, and meta-databases related to TBI, probable depression, and suicidal ideation are now publicly available on the FITBIR website. Even with limited data, harmonization of FITBIR studies can serve as the basis for ongoing TBI and mental health research. Analyses will be more robust in the future as more studies with relevant outcome data are added to the FITBIR database. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Characterizing and Comparing Evidence-Based Psychotherapy Utilization Among Veterans with Co-occurring PTSD and Substance Use Disorder.

Objective: The current study sought to describe a nationally representative sample of Veterans diagnosed with co-occurring PTSD and substance use disorder (SUD) who initiated and completed evidence-based psychotherapy (EBP) for PTSD, and explored whether completion rates differed by SUD subtype. Methods: Using electronic health record data from the Veterans Health Administration (VHA) Corporate Data Warehouse, Veterans with a dual diagnosis of PTSD and SUD who initiated either Cognitive Processing Therapy (CPT) or Prolonged Exposure (PE) between January 01, 2019 and July 16, 2019 were identified (N = 2,996). Logistic analyses were employed to determine whether there were differences in EBP completion rates among Veterans with an alcohol use disorder (AUD; n = 1,383) versus all other SUDs (n = 1,613). Results: On average, Veterans were 45 years old, and identified as male, White, and non-Hispanic. Logistic regression analyses revealed there was not a significant difference between Veterans with AUD only and other SUDs in the probability of completing EBP treatment, OR = 1.02, 95% CI =0.87, 1.17, p = 0.79. Conclusions: No differences in EBP completion rates were observed between SUD subtypes, indicating that EBPs for PTSD are tolerated well for individuals with various types of SUDs and may be offered as treatment options.

Neuropsychological Correlates of PTSD and Depressive Symptom Improvement in Compensatory Cognitive Training for Veterans With a History of Mild Traumatic Brain Injury.

INTRODUCTION: Mild traumatic brain injury (mTBI), depression, and PTSD are highly prevalent in post-9/11 veterans. With the comorbidity of depression and PTSD in post-9/11 veterans with mTBI histories and their role in exacerbating cognitive and emotional dysfunction, interventions addressing cognitive and psychiatric functioning are critical. Compensatory Cognitive Training (CCT) is associated with improvements in prospective memory, attention, and executive functioning and has also yielded small-to-medium treatment effects on PTSD and depressive symptom severity. We sought to examine neuropsychological correlates of PTSD and depressive symptom improvement in veterans with a history of mTBI who received CCT. MATERIALS AND METHODS: Thirty-seven post-9/11 veterans with mTBI histories and cognitive complaints received 10 weekly 120-minute CCT group sessions. Participants completed a baseline neuropsychological assessment, including tests of premorbid functioning, attention/working memory, processing speed, verbal learning/memory, and executive functioning, and completed psychiatric symptom measures (PTSD and depression) at baseline, post-treatment, and a 5-week follow-up. Paired samples t-tests were used to examine statistically significant changes in PTSD (total and symptom cluster scores) and depressive symptom scores over time. Pearson's correlations were calculated between neuropsychological scores and PTSD and depressive symptom change scores at post-treatment and follow-up. Neuropsychological measures identified as significantly correlated with psychiatric symptom change scores were entered as independent variables in multivariable regression analyses to examine their association with symptom change at post-treatment and follow-up. RESULTS: Over 50% of CCT participants had clinically meaningful improvement in depressive symptoms (≥17.5% score reduction), and over 20% had clinically meaningful improvement in PTSD symptoms (≥10-point improvement) at post-treatment and follow-up. Examination of PTSD symptom cluster scores revealed a statistically significant improvement in avoidance/numbing at follow-up. Bivariate correlations indicated that worse baseline performance on Category Fluency was moderately associated with PTSD symptom improvement at post-treatment. Worse performance on both Category Fluency and Category Switching Accuracy was associated with improvement in depressive symptoms at post-treatment and follow-up. Worse performance on Trail-Making Number-Letter Switching was also associated with improvement in depressive symptoms at follow-up. Subsequent regression analyses revealed that worse processing speed and worse aspects of executive functioning at baseline were associated with depressive symptom improvement at post-treatment and follow-up. CONCLUSIONS: Worse baseline performances on tests of processing speed and aspects of executive functioning were significantly associated with improvements in PTSD and depressive symptoms during the trial. Our results suggest that cognitive training may bolster skills that are helpful for PTSD and depressive symptom reduction and that those with worse baseline functioning may benefit more from treatment because they have more room to improve.

Inactivation of high-risk flags for suicide in the Veterans Health Administration: Association of documentation variation with suicide attempts.

Medical record high-risk flags for suicide indicate patients are receiving enhanced care and alert treating providers to patients' high-risk status. Risk of suicide mortality remains high after flag inactivation, suggesting a need to improve inactivation determinations. This study describes variation in flag inactivation documentation, examines whether documentation varies by patient or facility characteristics, and explores the association between inactivation documentation type and subsequent suicide attempts. In a national sample of veterans with a documented suicide attempt who received a high-risk flag for suicide (n = 224), medical record review was used to categorize provider documentation of the rationale and procedures for high-risk flag inactivation. Mixed-effects logistic regression models were used to examine patient and facility characteristics associated with flag inactivation documentation type and to examine the association between documentation type and subsequent suicide attempts. Flag inactivation documentation fell into one of two categories: documentation stating the patient no longer met criteria for the high-risk flag (minimal documentation; n = 98, 43.8%); and documentation that included a review of one or more criteria for high-risk flag inactivation (more than minimal documentation; n = 126, 56.3%). Flag inactivation documentation was not associated with patient or facility characteristics. Veterans with minimal documentation (vs. more than minimal) were more likely to have a suicide attempt after flag inactivation (adjusted odds ratio, AOR = 2.20; 95% CI [1.01, 4.78]; p = .046). Findings suggest a need to better understand flag inactivation procedures in place and to develop a set of standardized procedures to reduce risk of premature high-risk flag inactivation.

Can mild traumatic brain injury alter cognition chronically? A LIMBIC-CENC multicenter study.

OBJECTIVE: While outcome from mild traumatic brain injury (mTBI) is generally favorable, concern remains over potential negative long-term effects, including impaired cognition. This study examined the link between cognitive performance and remote mTBIs within the Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) multicenter, observational study of Veterans and service members (SMs) with combat exposure. METHOD: Baseline data of the participants passing all cognitive performance validity tests (n = 1,310) were used to conduct a cross-sectional analysis. Using multivariable regression models that adjusted for covariates, including age and estimated preexposure intellectual function, positive mTBI history groups, 1-2 lifetime mTBIs (nonrepetitive, n = 614), and 3 + lifetime mTBIs (repetitive; n = 440) were compared to TBI negative controls (n = 256) on each of the seven cognitive domains computed by averaging Z scores of prespecified component tests. Significance levels were adjusted for multiple comparisons. RESULTS: Neither of the mTBI positive groups differed from the mTBI negative control group on any of the cognitive domains in multivariable analyses. Findings were also consistently negative across sensitivity analyses (e.g., mTBIs as a continuous variable, number of blast-related mTBIs, or years since the first and last mTBI). CONCLUSIONS: Our findings demonstrate that the average veteran or SM who experienced one or more mTBIs does not have postacute objective cognitive deficits due to mTBIs alone. A holistic health care approach including comorbidity assessment is indicated for patients reporting chronic cognitive difficulties after mTBI(s), and strategies for addressing misattribution may be beneficial. Future study is recommended with longitudinal designs to assess within-subjects decline from potential neurodegeneration. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Mild traumatic brain injury, PTSD symptom severity, and behavioral dyscontrol: a LIMBIC-CENC study.

Background: Behavioral dyscontrol occurs commonly in the general population and in United States service members and Veterans (SM/V). This condition merits special attention in SM/V, particularly in the aftermath of deployments. Military deployments frequently give rise to posttraumatic stress disorder (PTSD) and deployment-related mild TBI traumatic brain injury (TBI), potentially leading to manifestations of behavioral dyscontrol. Objective: Examine associations among PTSD symptom severity, deployment-related mild traumatic brain injury, and behavioral dyscontrol among SM/V. Design: Secondary cross-sectional data analysis from the Long-Term Impact of Military-Relevant Brain Injury Consortium - Chronic Effects of Neurotrauma Consortium prospective longitudinal study among SM/V (N = 1,808). Methods: Univariable and multivariable linear regression models assessed the association and interaction effects between PTSD symptom severity, as assessed by the PTSD Checklist for the Diagnostic and Statistical Manual, 5th edition (PCL-5), and deployment-related mild TBI on behavioral dyscontrol, adjusting for demographics, pain, social support, resilience, and general self-efficacy. Results: Among the 1,808 individuals in our sample, PTSD symptom severity (B = 0.23, 95% CI: 0.22, 0.25, p < 0.001) and deployment-related mild TBI (B = 3.27, 95% CI: 2.63, 3.90, p < 0.001) were significantly associated with behavioral dyscontrol in univariable analysis. Interaction effects were significant between PTSD symptom severity and deployment mild TBI (B = -0.03, 95% CI: -0.06, -0.01, p = 0.029) in multivariable analysis, indicating that the effect of mild TBI on behavioral dyscontrol is no longer significant among those with a PCL-5 score > 22.96. Conclusion: Results indicated an association between PTSD symptom severity, deployment-related mild TBI, and behavioral dyscontrol among SM/V. Notably, the effect of deployment-related mild TBI was pronounced for individuals with lower PTSD symptom severity. Higher social support scores were associated with lower dyscontrol, emphasizing the potential for social support to be a protective factor. General self-efficacy was also associated with reduced behavioral dyscontrol.

Randomized controlled trials of mind-body interventions for posttraumatic stress disorder: a systematic review.

Mind-body interventions (MBIs) include mindfulness-based interventions (MiBIs), meditation- and mantra-based interventions (MMIs), and movement-based interventions (MoBIs). These approaches have demonstrated preliminary efficacy in improving posttraumatic stress disorder (PTSD) symptoms. However, previous systematic reviews and meta-analyses have noted that this area of research is limited by inadequate comparator conditions, heterogeneity of measurement, and absence of objective outcome measures. For these reasons, an updated review of the highest-quality evidence available is warranted. We used the Agency for Healthcare Research and Quality (AHRQ)-funded evidence tables for the PTSD-Repository to identify relevant studies and assess the risk of bias as follows: The search was conducted between June 2018 and June 2022, and databases included PTSDpubs (formerly PILOTS), Ovid® MEDLINE®, Cochrane CENTRAL, Embase®, the Cumulative Index to Nursing and Allied Health Literature (CINAHL®), SCOPUS, and PsycINFO®. Twenty-six randomized controlled trials met our inclusion criteria. After identifying studies and retrieving risk of bias information from the PTSD-Repository evidence tables, we extracted additional data and synthesized the evidence. The strength of evidence was rated as low for MiBIs and MMIs, largely due to contradicting results, inconsistent use of active versus passive comparators, and high risk of bias. The strength of evidence for MoBIs was rated as moderate due to individual studies consistently favoring the intervention and a relatively large number of studies and participants. Of the 26 included studies, only two included objective outcome measures. Implications for future MBI research and clinical applications for treating PTSD are discussed.

Neuropsychological Performance and Functional Capacity Following Mild Traumatic Brain Injury in Veterans.

OBJECTIVE: To examine the relationship between neuropsychological functioning and performance-based functional capacity in veterans with a history of mild traumatic brain injury (mTBI), as well as the moderating effects of age and psychiatric symptoms on this relationship. SETTING: Three Veterans Affairs medical centers. PARTICIPANTS: One hundred nineteen Iraq/Afghanistan veterans with a history of mTBI and self-reported cognitive difficulties. DESIGN: Cross-sectional, secondary data analysis of baseline measures in a randomized controlled trial. MAIN MEASURES: The main outcome measure, functional capacity, was assessed using the objective and performance-based University of California San Diego Performance-based Skills Assessment-Brief. A global deficit score (GDS) was created as a composite score for performance on a battery of neuropsychological measures assessing domains of attention, processing speed, executive functioning, and verbal memory performance. Posttraumatic stress disorder (PTSD) symptom severity was assessed using the PTSD Checklist-Military Version, and depressive symptom severity was assessed using the Beck Depression Inventory, Second Edition. RESULTS: Bivariate analyses indicated that worse neuropsychological performance (ie, higher GDS) and greater PTSD symptom severity were associated with worse communication abilities and worse overall functional capacity. Multiple linear regressions demonstrated that GDS and PTSD symptom severity explained 9% of the variance in communication and 10% of the variance in overall functional capacity; however, GDS emerged as the only significant predictor in both regressions. Age, PTSD, and depressive symptom severity did not moderate the relationship between GDS and overall functional capacity. Performance in the verbal learning and memory domain emerged as the strongest neuropsychological predictor of communication and overall functional capacity. CONCLUSIONS: Worse neuropsychological functioning was moderately associated with worse performance-based functional capacity, even when accounting for PTSD symptom severity. Verbal learning and memory was the primary neuropsychological domain driving the relationship with functional capacity; improvement in verbal learning and memory may translate into improved functional capacity.

Dietary Supplementation With Branched Chain Amino Acids to Improve Sleep in Veterans With Traumatic Brain Injury: A Randomized Double-Blind Placebo-Controlled Pilot and Feasibility Trial.

Study Objectives: Traumatic brain injury (TBI) is associated with chronic sleep disturbances and cognitive impairment. Our prior preclinical work demonstrated dietary supplementation with branched chain amino acids (BCAA: leucine, isoleucine, and valine), precursors to de novo glutamate production, restored impairments in glutamate, orexin/hypocretin neurons, sleep, and memory in rodent models of TBI. This pilot study assessed the feasibility and preliminary efficacy of dietary supplementation with BCAA on sleep and cognition in Veterans with TBI. Methods: Thirty-two Veterans with TBI were prospectively enrolled in a randomized, double-blinded, placebo-controlled trial comparing BCAA (30 g, b.i.d. for 21-days) with one of two placebo arms (microcrystalline cellulose or rice protein, both 30 g, b.i.d. for 21-days). Pre- and post-intervention outcomes included sleep measures (questionnaires, daily sleep/study diaries, and wrist actigraphy), neuropsychological testing, and blood-based biomarkers related to BCAA consumption. Results: Six subjects withdrew from the study (2/group), leaving 26 remaining subjects who were highly adherent to the protocol (BCAA, 93%; rice protein, 96%; microcrystalline, 95%; actigraphy 87%). BCAA were well-tolerated with few side effects and no adverse events. BCAA significantly improved subjective insomnia symptoms and objective sleep latency and wake after sleep onset on actigraphy. Conclusion: Dietary supplementation with BCAA is a mechanism-based, promising intervention that shows feasibility, acceptability, and preliminary efficacy to treat insomnia and objective sleep disruption in Veterans with TBI. A larger scale randomized clinical trial is warranted to further evaluate the efficacy, dosing, and duration of BCAA effects on sleep and other related outcome measures in individuals with TBI. Clinical Trial Registration: [http://clinicaltrials.gov/], identifier [NCT03990909].

Demographic, military, and health comorbidity variables by mild TBI and PTSD status in the LIMBIC-CENC cohort.

OBJECTIVE: To describe associations of demographic, military, and health comorbidity variables between mild traumatic brain injury (mTBI) history and posttraumatic stress disorder (PTSD) status in a sample of Former and current military personnel. SETTING: Participants recruited and tested at seven VA sites and one military training facility in the LIMBIC-CENC prospective longitudinal study (PLS), which examines the long-term mental health, neurologic, and cognitive outcomes among previously combat-deployed U.S. Service Members and Veterans (SM/Vs). PARTICIPANTS: A total of 1,540 SM/Vs with a history of combat exposure. Data were collected between 1/1/2015 through 3/31/2019. DESIGN: Cross-sectional analysis using data collected at enrollment into the longitudinal study cohort examining demographic, military, and health comorbidity variables across PTSD and mTBI subgroups. MAIN MEASURES: PTSD Checklist for DSM-5 (PCL-5), mTBI diagnostic status, Patient Health Questionnaire 9-item (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), AUDIT-C, and other self-reported demographic, military, and health comorbidity variables. RESULTS: Ten years following an index date of mTBI exposure or mid-point of military deployment, combat-exposed SM/Vs with both mTBI history and PTSD had the highest rates of depression symptoms, pain, and sleep apnea risk relative to SM/Vs without both of these conditions. SM/Vs with PTSD, irrespective of mTBI history, had high rates of obesity, sleep problems, and pain. CONCLUSION: The long-term symptom reporting and health comorbidities among SM/Vs with mTBI history and PTSD suggest that ongoing monitoring and intervention is critical for addressing symptoms and improving quality of life.

Mental health outcomes of adults hospitalized for COVID-19: A systematic review.

BACKGROUND: Patients hospitalized for COVID-19 may be at high risk of mental health (MH) disorders. This systematic review assesses MH outcomes among adults during and after hospitalization for COVID-19 and ascertains MH care utilization and resource needs. METHODS: We searched multiple medical literature databases for studies published December 2019 to March 2021. Studies of ≥ 200 participants were synthesized. One reviewer completed article selection, data abstraction and assessed study quality and strength of evidence, with verification by a second. RESULTS: Fifty articles met preliminary inclusion criteria; 19 articles that included ≥ 200 participants were synthesized. Evidence from these primarily fair-quality studies suggests many patients experience symptoms of depression (9-66%), anxiety (30-39%), and insomnia (24-40%) during and 3 months after hospitalization for COVID-19. However, patients infrequently receive a new MH disorder diagnosis 6 months after hospitalization (5% are diagnosed with a new mood disorder, 7% anxiety disorder, and 3% insomnia). Some hospitalized patients - including women and those with more severe COVID-19 - may be at higher risk of poor MH outcomes. Data on MH care utilization and resource needs are currently limited. LIMITATIONS: Most included studies were small, did not report the proportion of participants with preexisting MH disorders, and did not use comparison groups. CONCLUSIONS: While many patients experience MH symptoms after hospitalization for COVID-19, most do not go on to develop a new MH disorder. Future studies should report whether participants have preexisting MH disorders and compare patients hospitalized for COVID-19 to patients hospitalized for other causes.

Opioid and Sedative-Hypnotic Prescriptions Among Post-9/11 Veteran VA Users Nationwide With Traumatic Brain Injury, 2012-2020.

OBJECTIVE: Many post-9/11 Veterans have received Department of Veterans Affairs (VA) healthcare for traumatic brain injury (TBI). Pain conditions are prevalent among these patients and are often managed with opioid analgesics. Opioids may impose unique risks to Veterans with a history of TBI, especially when combined with other psychotropic medications. We examined receipt of opioid and sedative-hypnotic prescriptions among post-9/11 Veterans with TBI who received VA care nationally between 2012 and 2020. SETTING: Nationwide VA outpatient care. PARTICIPANTS: Veterans with, versus without, clinician-confirmed TBI based on the VA's Comprehensive TBI Evaluation (CTBIE) were followed up for subsequent years in which they received VA care. DESIGN: A historical cohort study. MAIN MEASURES: Proportions of Veterans who received opioid, benzodiazepine, and nonbenzodiazepine sedative-hypnotic prescriptions were compared by CTBIE outcome (TBI yes/no) and by year; overlaps between medication classes, long-term opioid therapy, and high-dose opioid therapy were also examined. Among those with confirmed TBI, logistic regression was used to examine associations between veteran characteristics and likelihood of these potentially high-risk opioid use outcomes. RESULTS: Among 69 752 Veterans with clinician-confirmed TBI, 26.9% subsequently received opioids. The prevalence receiving opioids each year increased from 2012 (16.7%) to 2014 (17.7%), and then decreased each of the following years through 2020 (5.8%). Among Veterans with TBI who received opioids, large proportions also received benzodiazepine (30.1%) and nonbenzodiazepine (36.0%) sedative-hypnotic prescriptions; these proportions also decreased in recent years. In both bivariable and multivariable regression models, Veterans' demographic, TBI, and clinical characteristics were associated with likelihood of potentially high-risk opioid use. CONCLUSIONS: VA opioid prescribing to Veterans with TBI has decreased in recent years but remains an important source of risk, particularly when considering coprescriptions of sedative-hypnotic medication. Understanding patterns of psychotropic prescription use among Veterans with TBI can highlight important healthcare and rehabilitation needs in this large patient cohort.

Associations Among PTSD and Postconcussive Symptoms in the Long-Term Impact of Military-Relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium Prospective, Longitudinal Study Cohort.

OBJECTIVE: To describe rates of mild traumatic brain injury (mTBI) with and without concurrent posttraumatic stress disorder a sample of former and current military personnel, and to compare the factor structure of the Neurobehavioral Symptom Inventory (NSI) based on whether participants sustained mTBI with and without a positive posttraumatic stress disorder (PTSD) screen. SETTING: Participants recruited and tested at 7 Veterans Affairs (VA) sites and 1 military training facility as part of a national, longitudinal study of mental health, physical, and cognitive outcomes among veterans and service members. Participants: Total of 1540 former and current military personnel with a history of combat exposure. DESIGN: Cross-sectional analysis of observational data, including confirmatory factor analysis. Main Measures: NSI and PTSD Checklist for DSM-5 (PCL-5). RESULTS: Most participants (81.5%) had a history of mTBI and almost half of these screened positive for PTSD (40.5%); only 23.9% of participants without a history of mTBI screened positive for PTSD. Participants with a history of mTBI reported higher elevations of NSI and PCL-5 symptoms compared with those without a history of mTBI. Confirmatory factor analyses of the NSI demonstrated good model fit using a 4-factor structure (somatosensory, affective, cognitive, and vestibular symptoms) among groups of participants both with and without a history of mTBI. CONCLUSION: Symptoms of mTBI and PTSD are strongly associated with each other among veterans and service members with a history of combat exposure. The 4-factor NSI structure is supported among participants with and without a history of mTBI. These findings suggest the potential benefit of a holistic approach to evaluation and treatment of veterans and service members with concurrent and elevated postconcussive and posttraumatic stress symptoms.

Mental Health Symptoms Among Veteran VA Users by Tinnitus Severity:A Population-based Survey.

INTRODUCTION: Tinnitus is prevalent among Service members and Veterans and is often comorbid with mental health disorders. Associations between the severity of individuals' tinnitus and mental health symptoms are not well described. MATERIALS AND METHODS: We conducted a population-based survey of a stratified random sample of 1,800 Veterans diagnosed with tinnitus. We used the Tinnitus Functional Index to measure tinnitus severity and the Primary Care-Posttraumatic Stress Disorder (PTSD) screen and the Hospital Anxiety and Depression Scale to assess PTSD, depression, and anxiety. Descriptive statistics and bivariable and multivariable regression models were used to estimate associations between Veterans' tinnitus severity and mental health symptoms. Inverse probability weights were used to account for sample stratification and survey non-response. Multivariable odds ratios (ORs) and 95% confidence intervals (CIs) controlled for Veterans' demographics, military history, and health diagnoses. RESULTS: A total of 891 Veterans completed surveys (adjusted response rate = 53%). Large proportions rated their tinnitus as severe (29.4%; 95% CI: 27.2-31.6) or very severe (18.7%; 95% CI: 16.8-20.5). In multivariable regression models, and compared with Veterans with none/mild tinnitus, the likelihood of screening positive for PTSD was increased for those who reported moderate (OR = 4.0; 95% CI: 1.6-10.3), severe (OR = 7.5; 95% CI: 3.1-18.5), or very severe (OR = 17.5; 95% CI: 4.4-70.0) tinnitus. Similarly, Veterans' likelihood of positive depression screens were elevated for those with moderate (OR = 2.6; 95% CI: 1.1-5.9), severe (OR = 3.0; 95% CI: 1.4-6.5), or very severe (OR = 15.5; 95% CI: 4.3-55.5) tinnitus, as was the likelihood of positive anxiety screens for those with severe (OR = 2.6; 95% CI: 1.1-6.3) or very severe (OR = 13.4; 95% CI: 4.0-44.3) tinnitus. CONCLUSIONS: Mental health symptoms are strongly associated with Veterans' tinnitus severity. A better understanding of the interplay between these conditions may help improve the provision of interdisciplinary (Audiology and Mental Health) care for Service members and Veterans.

Predictors of Intervention Adherence in Compensatory Cognitive Training for Veterans With a History of Mild Traumatic Brain Injury.

OBJECTIVE: The purpose of this study was to determine modifiable predictors of intervention adherence in a study of group-based Compensatory Cognitive Training (CCT) for Iraq/Afghanistan War veterans with a history of mild traumatic brain injury (mTBI). METHODS: One hundred twenty-three veterans enrolled in a randomized controlled trial of a 10-week CCT intervention (54 assigned to CCT) and were evaluated at baseline, 5 weeks, 10 weeks, and 15 weeks. CCT adherence was determined by the number of CCT sessions attended, with more sessions indicative of greater adherence. Baseline demographic and clinical characteristics, and subjective and objective neuropsychological performance, were examined in relation to CCT session attendance. RESULTS: Older age and worse attention performance at baseline were associated with higher CCT attendance rates. CONCLUSIONS: This study generates preliminary evidence for potential modifiable neuropsychological factors that may improve engagement in CCT interventions.

A Systematic Review of Therapeutic Interventions and Management Strategies for Gulf War Illness.

INTRODUCTION: After the 1990 to 1991 conflict in the Persian Gulf, many Gulf War Veterans began reporting numerous unexplained symptoms including, but not limited to, systemic pain, fatigue, flu-like symptoms, and difficulty with memory/concentration. These symptom clusters are now referred to as Gulf War Illness (GWI). Although the etiology of GWI is still debated, as many as 250,000 former service members have been continually suffering from GWI since 1991, making the need for treatment urgent. A broad variety of treatments have been considered for GWI, but there has not been a broad and comprehensive assessment of what is known and not known about GWI treatment. We conducted a systematic review to catalogue the types of treatments that have been examined for GWI, to evaluate the effectiveness and harms of these interventions, and to identify promising and ongoing areas of future GWI treatment research. MATERIALS AND METHODS: We searched electronic databases, trial registries, and reference lists through September 2019 for randomized controlled trial and nonrandomized controlled trial and cohort studies directly comparing interventions for Veterans with GWI to each other, placebo, or usual care. We abstracted data on study design, demographics, interventions, and outcomes. Two reviewers independently assessed studies for inclusion, quality, and strength of evidence (SOE) using prespecified criteria. We resolved discordant ratings by discussion and consensus. RESULTS: We identified 12 randomized controlled trials, each of which examined a different intervention for GWI. We found moderate SOE that cognitive behavioral therapy and exercise, separately and in combination, were associated with improvements in several GWI symptom domains. There was low SOE of benefit from two mindfulness-based interventions and continuous positive airway pressure (CPAP). Mindfulness-based stress reduction improved pain, cognitive functioning, fatigue, depression, and posttraumatic stress disorder (PTSD), whereas mind-body bridging improved fatigue, depression, posttraumatic stress disorder, and sleep, although pain and other outcomes did not improve. Continuous positive airway pressure improved overall physical health, pain, cognitive functioning, fatigue, mental health, and sleep quality in a small study of Veterans with sleep-disordered breathing and GWI. We found moderate SOE that doxycycline is ineffective for GWI in mycoplasma DNA-positive Veterans and increases the risk of adverse events compared with placebo. We also found 33 ongoing, single-arm pilot, or unpublished studies examining a variety of interventions. CONCLUSION: Cognitive behavioral therapy (moderate SOE), exercise (moderate SOE), and mindfulness-based interventions (low SOE) may be effective in improving several symptom domains in patients with GWI. Doxycycline was ineffective and associated with harms (moderate SOE). Larger, more rigorous studies are needed to confirm the benefits found in completed trials. A wide array of treatments are being assessed in ongoing trials. A sufficient evidence base will need to be developed to guide clinicians about which treatments are most likely to be effective in clinical practice and which treatments should be avoided.

Development of the PTSD-Repository: A Publicly Available Repository of Randomized Controlled Trials for Posttraumatic Stress Disorder.

Given the extensive research on posttraumatic stress disorder (PTSD) treatment, a single, updatable repository of data from PTSD treatment studies would be useful for clinical, research, and policy stakeholders. To meet this need, we established a preliminary dataset of abstracted PTSD trial data, which serve as the basis for the PTSD Trials Standardized Data Repository (PTSD-Repository), maintained by the National Center for PTSD (NCPTSD). We followed systematic review methods to identify published randomized controlled trials (RCTs) of PTSD interventions. We consulted with a panel of experts to determine a priori inclusion criteria, ensure that we captured all relevant studies, and identify variables for abstraction. We searched multiple databases for materials published from 1980 to 2018 and reviewed reference lists of relevant systematic reviews and clinical practice guidelines. In total, 318 RCTs of PTSD interventions that enrolled almost 25,000 participants were included. We abstracted 337 variables across all studies, including study, participant, and intervention characteristics as well as results. In the present paper, we describe our methods and define data elements included in the data tables. We explain coding challenges, identify inconsistencies in reporting across study types, and discuss ways stakeholders can use PTSD-Repository data to enhance research, education, and policy. The abstracted data are currently publicly available on the NCPTSD website and can be used for future systematic reviews and identifying research gaps and as an information resource for clinicians, patients, and family members.
