Efficacy and acceptability of a home-based, family-inclusive intervention for veterans with TBI: A randomized controlled trial

Exploring the goals and outcomes of adults with severe acquired brain injury participating in an extended inpatient brain injury rehabilitation unit in Australia

PURPOSE

To explore the rehabilitation goals and evaluate goal attainment outcomes of people with severe acquired brain injury (ABI), and investigate the relationship between goal engagement and goal attainment.

MATERIALS AND METHODS

Mixed-methods cohort study with twenty-nine adults with severe ABI in Australia. Demographic data, goal statements and pre-post program Goal Attainment Scale scores as well as Goal Engagement Scale scores were collected. Goals were coded using inductive content analysis and categorised by ICF component and domain. Goal attainment within ICF categories was described and compared using descriptive statistics. Pre-post program change in goal attainment was evaluated using Wilcoxon signed rank tests and correlations between goal engagement and attainment was explored using Spearman's (rho).

RESULTS

94% of 320 goals were categorised as ICF Activity and Participation. There was significant improvement in goal attainment between admission and discharge (z=-0.47, p < 0.01). There was no significant relationship between goal engagement and goal attainment however there was a positive association between engagement in goal setting at admission and discharge.Conclusions: This interdisciplinary, inpatient rehabilitation program underpinned by key-worker facilitated person-centred, role-based goal setting resulted in goal attainment in chosen goals, which were primarily activity and participation-focused.

Process evaluation of a complex intervention evaluating the effectiveness of home-based rehabilitation in the chronic phase of traumatic brain injury

PURPOSE

To perform a process evaluation of a randomized controlled trial (RCT) evaluating a manualized intervention aiming to ameliorate long-term symptoms of traumatic brain injury (TBI) by assessing implementation fidelity, delivery context and acceptability of the intervention.

METHODS

Data from 60 participants were collected during recruitment, intervention delivery and outcome data collection in the RCT. Enrollment records, logs and checklists documented the delivery of the intervention (implementation fidelity) and the collaboration with family members and outside collaborators (delivery context). Attendance-rate, self-reported acceptability and willingness to participate in future studies were used to assess the acceptability of the intervention.

RESULTS

The main elements and dose of the intervention were delivered as intended with an excellent adherence to the manual items. Family members co-participated in the intervention for 39 (65%) of the participants. Outside collaborators were contacted for 32 (53%) of the participants. Acceptability scores were high for participants, family members and therapists.

CONCLUSIONS

The intervention was successfully delivered with high acceptability. This process evaluation informs researchers, clinicians and stakeholders about important factors influencing the outcomes of the intervention that should be considered in clinical implementation of rehabilitation interventions.

Family member reported symptom burden, predictors of caregiver burden and treatment effects in a goal-oriented community-based randomized controlled trial in the chronic phase of traumatic brain injury

BACKGROUND

Family members are often affected by the long-term consequences of traumatic brain injury, but are rarely involved in rehabilitation programs in the chronic phase. We thus do not know what family members´ main concerns are in the chronic phase, what factors are associated with perceived caregiver burden, and whether family members´ health and functioning improves due to rehabilitation efforts received by the patients. This study explored family-members` functioning, predictors of caregiver burden and effect for family members of a goal-oriented intervention in the chronic phase of traumatic brain injury.

METHODS

Family members self-reported data measuring their caregiver burden, depression, general health, loneliness, and their evaluation of patient competency in everyday life, patient awareness levels, main problem areas (target outcomes) for the patient related to the brain injury, and demographic data were collected. Regression models were used to explore predictors of caregiver burden, and mixed models analysis was used to explore treatment effects.

RESULTS

In total, 73 family members were included, 39 in the intervention group and 34 in the control group. Moderate to high caregiver burden was reported by 40% of family members, and 16% experienced clinical levels of depression. Family member loneliness and their evaluation of the patient`s level of functional competency explained 57% of the variability in caregiver burden. There were no treatment-related changes in caregiver burden, family member depression or general health. At T2 there was however a significant reduction in how family members rated severity of target outcomes that the family members had nominated at baseline (-0.38, 95% CI, -0.75 to -0.02, p = 0.04), but not for the target outcomes the patients had nominated.

CONCLUSIONS

A significant proportion of family members to patients in the chronic phase of TBI continue to experience challenging caregiver burden and emotional symptoms. Both family member-related and patient factors contribute to caregiver burden. Interventions targeting patient complaints do not automatically alleviate family members´ burden. It is important to address social support for family members early after injury, and there is a need for more interventions specifically targeting family members´ needs.

The trial was registered at ClinicalTrials.gov, NCT03545594 on the 4th of June 2018.

Building Family Interventions for Scalability and Impact

Family nursing researchers are charged with addressing the conceptual and methodological underpinnings of family research when developing family-focused interventions. Step-by-step guidance is needed that integrates current science of intervention development with family science and helps researchers progress from foundational work to experimental work with policy integration. The purpose of this manuscript is to provide pragmatic, evidence-based guidance for advancing family intervention research from foundational work through efficacy testing. Guidance regarding the development of family interventions is presented using the first three of Sidani's five-stage method: (a) foundational work to understand the problem targeted for change; (b) intervention development and assessment of acceptability and feasibility; and (c) efficacy testing. Each stage of family intervention development is described in terms of process, design considerations, and policy and practice implications. Examples are included to emphasize the family lens. This manuscript provides guidance to family scientists for intervention development and implementation to advance family nursing science and inform policy.

The Participation Assessment with Recombined Tools-Objective (PART-O): measurement properties of the Norwegian version after traumatic brain injury

OBJECTIVE

To translate and evaluate the validity of the Participation Assessment with Recombined Tools-Objective (PART-O) in a Norwegian context.

METHODS

One hundred and twenty persons with TBI with verified intracranial lesions and persistent symptoms lasting more than 2 years, included in a randomized controlled trial, rated their participation using the PART-O at baseline. The PART-O with its three subscales (Productivity, Out and About, and Social Relations) was translated to Norwegian. Descriptive statistics, Cronbach's alpha, Rasch analysis, and correlation analysis were applied.

RESULTS

The Rasch analysis indicated a unidimensional construct of PART-O and its subscales (χ2 < 12.69, p > 0.28). The internal consistency was moderate (Cronbach's alpha 0.48-0.52) and there was a need to reduce scaling options for most of the items. The Out and About and Productivity subscales had considerable floor effects. PART-O showed moderate positive correlation to TBI-related quality of life and global functioning.

CONCLUSIONS

PART-O and its subscales reflect unidimensional aspects of participation. In the present Norwegian TBI population the original scaling of PART-O was too detailed for all subscales. The floor effects and suboptimal targeting between items and subjects participation level of the Out and About subscale is a matter of concern.

Children's, parents', and teachers' experiences of the feasibility of a telerehabilitation intervention for children with acquired brain injury in the chronic phase - a qualitative study of acceptability and participation in the Child In Context Intervention (CICI)

BACKGROUND

This is a qualitative feasibility study of the Child in Context Intervention (CICI). The CICI is an individualized, goal-oriented and home-based tele-rehabilitation intervention which targets everyday functioning of children (6-16 years) with acquired brain injury in the chronic stage, and their families, one year or more after insult, who have ongoing challenges (physical, cognitive, behavioral, social and/or psychological). The aim of this study is to better understand how children, parents and teachers experienced participation and acceptability; to develop knowledge about the mechanisms of change, and to explore how the CICI was tailored to the context.

METHODS

Six families and schools participated in the intervention, which comprised seven tele-rehabilitation sessions in which the child and parent participated, one in-person parent seminar and four digital school meetings. A multidisciplinary team delivered the intervention to 23 participants over a 4- to 5-month period. The intervention involved psychoeducation about targeted acquired brain injury-related problems, such as fatigue, pain, or social challenges. All but one consented to participate in the current digital interview study. The data were analyzed using content analysis.

RESULTS

The experience of participation and acceptability varied among the children. Attendance was consistently high; the child participants felt mostly listened to and could influence goal setting and strategies. However, engaging and motivating the child participants proved somewhat challenging. The parents found the CICI rewarding, useful and relevant. However, they had different experiences regarding which intervention component they perceived as most helpful. Some argued in favor of the 'whole intervention', while others highlighted new knowledge, SMART goals or the school collaboration. The teachers found the intervention acceptable and useful but wanted a better meeting plan. They had difficulties in finding time for meetings, emphasized the involvement of school leaders, and appreciated the digital format.

CONCLUSIONS

Overall, the intervention was perceived as acceptable, and the participants felt that the various intervention components contributed to improvements. The CICI's flexibility facilitated tailoring to different contexts based on the children's functional level. The digital format saved time and provided flexibility regarding the amount of attendance but limited full participation from children with more severe cognitive impairments.

Effect of an Individually Tailored and Home-Based Intervention in the Chronic Phase of Traumatic Brain Injury: A Randomized Clinical Trial

Importance

Traumatic brain injury (TBI) can cause long-lasting and heterogeneous difficulties that require an individually tailored approach to rehabilitation. However, high-quality studies of treatment options in the chronic phase of TBI are lacking.

Objective

To evaluate the effect of a home-based, individualized, and goal-oriented rehabilitation intervention in the chronic phase of TBI.

Design, Setting, and Participants

This study was an intention-to-treat parallel-group assessor-blinded randomized clinical trial with 1:1 randomization to an intervention or control group. Participants included adults in southeastern Norway who had sustained a TBI more than 2 years earlier, lived at home, and had ongoing TBI-related difficulties. A population-based sample of 555 individuals were invited, and 120 were included. Participants were assessed at baseline, 4 months, and 12 months after inclusion. Specialized rehabilitation therapists provided the intervention in patients' homes or via video conference and telephone. Data collection was conducted between June 5, 2018, and December 14, 2021.

Interventions

The intervention group received an 8-session individually tailored and goal-oriented rehabilitation program over 4 months. The control group received usual care in their municipality.

Main Outcomes and Measures

Preestablished primary outcomes were disease-specific health-related quality of life (HRQOL; measured by the Quality of Life After Brain Injury [QOLIBRI] overall scale) and social participation (measured by the Participation Assessment With Recombined Tools-Objective [PART-O] social subscale). Preestablished secondary outcomes included generic HRQOL (measured by the EuroQol 5-dimension 5-level [EQ-5D-5L] questionnaire), difficulty with TBI-related problem management (target outcomes; mean severity calculated across 3 main self-identified problem areas that were individually measured using a 4-point Likert scale), TBI symptoms (measured by the Rivermead Post Concussion Symptoms Questionnaire [RPQ]), psychological distress (depression and anxiety; measured by the Patient Health Questionnaire 9-item scale and the Generalized Anxiety Disorder 7-item scale [GAD-7], respectively), and functional competency (measured by the Patient Competency Rating Scale).

Results

Among 120 participants in the chronic phase of TBI, the median (IQR) age was 47.5 (31.0-55.8) years, and the median (IQR) time since injury was 4 (3-6) years; 85 (70.8%) were male. A total of 60 participants were randomized to the intervention group, and 60 were randomized to the control group. Between baseline and 12 months, no significant between-group effects were found for the primary outcomes of disease-specific HRQOL (QOLIBRI overall scale score: 2.82; 97.5% CI, -3.23 to 8.88; P = .30) or social participation (PART-O social subscale score: 0.12; 97.5% CI, -0.14 to 0.38; P = .29). At 12 months, the intervention group (n = 57) had significantly higher generic HRQOL (EQ-5D-5L score: 0.05; 95% CI, 0.002-0.10; P = .04) and fewer symptoms of TBI (RPQ total score: -3.54; 95% CI, -6.94 to -0.14; P = .04) and anxiety (GAD-7 score: -1.39; 95% CI, -2.60 to -0.19; P = .02) compared with the control group (n = 55). At 4 months only, the intervention group (n = 59) had significantly less difficulty managing TBI-related problems (target outcomes mean severity score: -0.46, 95% CI, -0.76 to -0.15; P = .003) compared with the control group (n = 59). No adverse events were reported.

Conclusions and Relevance

In this study, no significant results were observed for the primary outcomes of disease-specific HRQOL or social participation. However, the intervention group reported improvements in secondary outcomes (generic HRQOL and symptoms of TBI and anxiety) that were maintained at 12-month follow-up. These findings suggest that rehabilitation interventions could help patients even in the chronic phase of TBI.

Calling on clinicians to get social and emotional

OBJECTIVE

Disorders of social cognition, such as difficulties with emotion perception, alexithymia, Theory of Mind (ToM), empathy and disorders of emotion regulation, are prevalent and pervasive problems across many neurological, neurodevelopmental and neuropsychiatric conditions. Clinicians are familiar with how these difficulties present but assessment and treatment has lagged behind other traditional cognitive domains, such as memory, language and executive functioning.

METHOD

In this paper, we review the prevalence and degree of impairment associated with disorders of social cognition and emotion regulation across a range of clinical conditions, with particular emphasis on their relationship to cognitive deficits and also real-world functioning. We reported effects sizes from published meta-analyses for a range of clinical disorders and also review test usage and available tests.

RESULTS

In general, many clinical conditions are associated with impairments in social cognition and emotion regulation. Effect sizes range from small to very large and are comparable to effect sizes for impairments in nonsocial cognition. Socio-emotional impairments are also associated with social and adaptive functioning. In reviewing prior research, it is apparent that the standardized assessment of social cognition, in particular, is not routine in clinical practice. This is despite the fact that there are a range of tools available and accruing evidence for the efficacy of interventions for social cognitive impairments.

CONCLUSION

We are using this information to urge and call for clinicians to factor social cognition into their clinical assessments and treatment planning, as to provide rigorous, holistic and comprehensive person-centred care.

Associations between protective resources and family functioning after traumatic brain injury: A cross-sectional study using a structural equation modeling approach

BACKGROUND

A strength-based approach in the rehabilitation after traumatic brain injury (TBI) is recommended for patients and their families. However, further exploration of the complexity of individual and family factors is needed.

OBJECTIVE

To explore the associations between individual protective resources in patients and family members and the overall family functioning using a strength-based approach.

METHODS

Secondary analysis of data collected at baseline in a randomized controlled trial. Structural equation modeling with two latent constructs and six observed variables was performed. Outcome measures included the Resilience Scale for Adults, the Mental Component Summary (SF-36), the General Self-Efficacy Scale, and the Family Adaptability and Cohesion Evaluation Scale-IV.

RESULTS

Hundred and twenty-two participants (60 patients, 62 family members) with a mean age of 43 years were included at a median of 11 months post-injury. The final model demonstrated a strong covariance (coefficient = 0.61) between the latent Protective construct and Family functioning. Model-fit statistics indicated an acceptable fit to the data.

CONCLUSION

Higher levels of protective resources (resilience, self-efficacy, and mental HRQL) were positively associated with family functioning. These resources should be further assessed in patients and their families, to identify factors that can be strengthened through TBI rehabilitation intervention.

Vocational Outcomes of Service Members and Veterans After Traumatic Brain Injury: A Scoping Review

OBJECTIVE

The purpose of this scoping review was to evaluate the current literature related to vocational outcomes among US service members and veterans with traumatic brain injury (TBI).

METHODS

Seven research databases (Ovid MEDLINE, PsycINFO, EMBASE, CINAHL Plus, Cochrane Library, Scopus, and SPORTDiscus) were queried for human studies between the database inception and February, 2020. We included studies that focused on US service members and veterans who sustained a TBI and their vocational outcomes. Conference abstracts, systematic reviews, literature reviews, editorials, consensus reports, commentaries, dissertations, and qualitative studies were excluded. Two rounds of independent reviews were performed. Details of study design, intervention, and vocational outcomes were recorded.

RESULTS

The search yielded 5667 articles; 48 articles met inclusion criteria. Forty-three studies were observational (90%), and 5 were randomized controlled trials. A majority of interventions were in the outpatient setting (71%). Interventions related to return to work and duty utilized physical therapy and occupational therapy to address cognitive skills and functional deficits and provide supportive employment.

CONCLUSION

Community reintegration research among service members and veterans with brain injuries is underdeveloped. Because of heterogeneity of severity and smaller sample sizes, no consensus was reached on interventions that improve vocational outcomes. Evidence thus far suggests that future studies should incorporate an interdisciplinary team approach beyond physical therapy and occupational therapy, longer-term outcomes, and sample subgroups.

Community-Based Interventions After Acquired Brain Injury-A Systematic Review of Intervention Types and Their Effectiveness

OBJECTIVES

Comprehensive review of existing types and effectiveness of community-based interventions delivered to adults (mean age 18-65 years) with long-lasting (≥6 months) difficulties following acquired brain injury (ABI).

DESIGN

Systematic review of controlled intervention studies published until February 2021.

MAIN MEASURES

Systematic searches in databases (MEDLINE, PsycINFO, Database of Abstracts of Reviews of Effects [Cochrane Library], and Cochrane Central Register of Controlled Trials [Cochrane Library]) and inclusion of English peer-reviewed full-text articles; randomized or controlled community-based intervention studies; sample size of 20 or more participants; and 3 or more intervention sessions. Two reviewers independently extracted data for the synthesis and assessed the methodological quality. Data extraction included study characteristics, demographics of participants, content and dose of intervention, outcome measures, and findings.

RESULT

The search returned 7386 publications, of which 49 eligible studies were included, revealing a diverse range of community-based interventions and a myriad of outcome measures applied for assessing functional capacities, participation, and quality of life in the chronic phase of ABI. Intervention types encompassed 14 holistic, 23 physical, and 12 specific interventions. A large heterogeneity regarding intervention frequency and intensity was found. Meta-analyses performed on the holistic, physical, and specific interventions did not indicate any significant pooled effects but showed highly variable effects between individuals, both in persons with traumatic and nontraumatic brain injuries.

CONCLUSIONS

Because of lack of pooled effects within types of community-based interventions, specific evidence-based recommendations within holistic, physical, and specific interventions designed to mitigate long-lasting ABI problems cannot be made. This review highlights the need for future studies to address methodological issues concerning larger sample size, lack of clear description interventions and comparator, missing reports of effects in change scores, need for consistent use of recommended outcome measures, and investigating the wide variety in intervention responsiveness among participants with ABI. Systematic review registration: PROSPERO (CRD42019124949).

Patient-Reported Problem Areas in Chronic Traumatic Brain Injury

OBJECTIVE

The aims of this study were to (1) assess self-reported main problem areas reported by patients with traumatic brain injury (TBI) and their family members in the chronic phase, and (2) compare the self-prioritized problems with difficulties captured by questionnaires and neuropsychological screening through linking to the International Classification of Functioning, Disability and Health (ICF).

SETTING

Outpatient clinic at the Oslo University Hospital, Norway.

PARTICIPANTS

In total, 120 patients with TBI were recruited, of whom, 78 had a participating family member. Eligibility criteria were a clinical TBI diagnosis with verified intracranial injury, living at home, aged 18 to 72 years, 2 years or more postinjury, and experiencing perceived TBI-related difficulties, reduced physical and mental health, or difficulties with participation in everyday life. Patients with severe psychiatric or neurological disorders or inability to participate in goal-setting processes were excluded.

DESIGN

Cross-sectional.

MAIN MEASURES

Target Outcomes, that is, 3 main TBI-related problem areas reported by patients and family members, collected in a semistructured interview; standardized questionnaires of TBI-related symptoms, anxiety, depression, functioning, and health-related quality of life; neuropsychological screening battery.

RESULTS

Target Outcomes were related to cognitive, physical, emotional, and social difficulties. Target Outcomes were linked to 12 chapters and 112 distinct categories in the ICF, while standardized measures only covered 10 chapters and 28 categories. Some aspects of post-TBI adjustment were found to be insufficiently covered by the ICF classification, such as identity issues, lack of meaningful activities, and feeling lonely.

CONCLUSION

The Target Outcomes approach is a useful assessment method in a population with chronic TBI. The standardized questionnaires capture the spectrum of problems, whereas the Target Outcomes approach captures the prioritized individual problems hindering everyday life after TBI. While the standardized measures are an irreplaceable part of the assessment, Target Outcomes ensures patient involvement and may help clinicians better tailor relevant rehabilitation efforts.

Feasibility and Acceptability of a Complex Telerehabilitation Intervention for Pediatric Acquired Brain Injury: The Child in Context Intervention (CICI)

The current study is a feasibility study of a randomized controlled trial (RCT): the Child in Context Intervention (CICI). The CICI study is an individualized, goal-oriented and home-based intervention conducted mainly through videoconference. It targets children with ongoing challenges (physical, cognitive, behavioral, social and/or psychological) after acquired brain injury (ABI) and their families at least one year post injury. The CICI feasibility study included six children aged 11–16 years with verified ABI-diagnosis, their families and their schools. The aim was to evaluate the feasibility of the intervention components, child and parent perceptions of usefulness and relevance of the intervention as well as the assessment protocol through a priori defined criteria. Overall, the families and therapists rated the intervention as feasible and acceptable, including the videoconference treatment delivery. However, the burden of assessment was too high. The SMART-goal approach was rated as useful, and goal attainment was high. The parents’ ratings of acceptability of the intervention were somewhat higher than the children’s. In conclusion, the CICI protocol proved feasible and acceptable to families, schools and therapists. The assessment burden was reduced, and adjustments in primary outcomes were made for the definitive RCT.

Organization of rehabilitation services in randomized controlled trials - which factors influence functional outcome? A systematic review

Objective

To identify factors related to the organization of rehabilitation services that may influence patients’ functional outcome and make recommendations for categories to be used in the reporting of rehabilitation interventions.

Data Sources

A systematic review based on a search in MEDLINE indexed journals (MEDLINE [OVID], Cumulative Index of Nursing and Allied Health Literature, PsycINFO, Cochrane Central Register of Controlled Trials) until June 2019.

Study Selection

In total 8587 candidate randomized controlled trials reporting on organizational factors of multidisciplinary rehabilitation interventions and their associations with functional outcome. An additional 1534 trials were identified from June 2019 to March 2021. Data Extraction: Quality evaluation was conducted by 2 independent researchers. The organizational factors were classified according to the International Classification for Service Organization in Health-related Rehabilitation 2.0.

Data Synthesis

In total 80 articles fulfilled the inclusion criteria. There was a great heterogeneity in the terminology and reporting of service organization across all studies. Aspects of Settings including the Mode of Service Delivery was the most explicitly analyzed organizational category (44 studies). The importance of the integration of rehabilitation in the inpatient services was supported. Furthermore, several studies documented a lack of difference in outcome between outpatient vs inpatient service delivery. Patient Centeredness, Integration of Care, and Time and Intensity factors were also analyzed, but heterogeneity of interventions in these studies prohibited aggregation of results.

Conclusions

Settings and in particular the way the services were delivered to the users influenced functional outcome. Hence, it should be compulsory to include a standardized reporting of aspects of service delivery in clinical trials. We would also advise further standardization in the description of organizational factors in rehabilitation interventions to build knowledge of effective service organization.

A systematic review on integrated care for traumatic brain injury, mental health, and substance use

Traumatic brain injuries (TBI) and mental health or substance use disorders (MHSU) are global public health concerns due to their prevalence and impact on individuals and societies. However, care for individuals with TBI and MHSU remains fragmented with a lack of appropriate services and supports across the continuum of healthcare. This systematic review provided an evidence-based foundation to inform opportunities to mobilize and adapt existing resources to integrate care for individuals with TBI and MHSU by comprehensively summarizing existing integrated activities and reported barriers and facilitators to care integration. MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, Sociological Abstracts, and Dissertations & Theses Global were independently reviewed by two reviewers based on pre-determined eligibility criteria. Data on the integration activity, level and type of integration, reported barriers and facilitators, and the strategies aligning with the World Health Organization’s (WHO) Framework on Integrated Person-Centred Care were extracted to form the basis for a narrative synthesis. Fifty-nine peer-reviewed articles were included, describing treatments (N = 49), programs (N = 4), or screening activities (N = 7). Studies discussing clinical integration at the micro- (N = 38) and meso- (N = 10) levels, service integration at the micro- (N = 6) and meso- (N = 5) levels, and functional integration at the meso-level (N = 1) were identified. A minority of articles reported on facilitators (e.g., cognitive accommodations in treatment plans; N = 7), barriers (e.g., lack of education on cognitive challenges associated with TBI; N = 2), or both (N = 6), related to integrating care. This review demonstrated that integrated TBI and MHSU care already exists across a range of levels and types. Given the finite and competing demands for healthcare resources, cognitive accommodations across treatment plans to facilitate integrated TBI and MHSU care should be considered. Multidisciplinary teams should also be explored to provide opportunities for education among health professionals so they can be familiar with TBI and MHSU.

Rehabilitation for children with chronic acquired brain injury in the Child in Context Intervention (CICI) study: study protocol for a randomized controlled trial

BACKGROUND

Pediatric acquired brain injury (pABI) is associated with long-term cognitive, behavioral, social, and emotional problems, which may affect the quality of life, school, and family functioning. Yet, there is a lack of evidence-based community-centered rehabilitation programs for chronic pABI and these children do not systematically receive comprehensive rehabilitation. The Child In Context Intervention (CICI) study is a pragmatic randomized controlled trial (RCT) for children with chronic pABI, which aims to evaluate the effectiveness of an individualized and goal-oriented intervention targeting everyday functioning of the child and family.

METHODS

Children aged 6-16 years with MRI/CT-verified intracranial abnormalities will be included in the CICI study if they have persistent self- or parent-reported cognitive, emotional, and/or behavioral challenges 1 year or more after insult and attend school regularly. A total of 70 families will be randomized 1:1 to an intervention or a control group. The intervention consists of seven family sessions, one parent seminar, and four school sessions delivered over approximately 6 months. The parent seminar will be held in person, and the other sessions will mainly be video based. The children's and families' self-reported major challenges in everyday life will be targeted using SMART goals. Evidence-based strategies, when available, will be applied to achieve the goals, combined with psychoeducation. Goal attainment scaling (GAS) will be used to evaluate goal attainment. Data is collected at baseline and after approximately 6 and 9 months. External assessors are blinded to group allocation. Primary outcomes are parent-reported brain injury symptoms in children and parenting self-efficacy at 9 months of follow-up. Secondary outcomes include child-reported brain injury symptoms, quality of life, executive functioning in daily life, parent emotional symptoms, family functioning, and unmet family health care needs. A process evaluation will be conducted.

DISCUSSION

The current study provides an innovative approach to rehabilitation for children in the chronic phase of ABI and their families. This complex intervention may contribute to the development of evidence-based, high-quality rehabilitation for a large patient group, which is underrepresented in clinical research. It may also improve collaboration between specialized rehabilitation facilities, schools, and local health care services. Inclusion for the trial started in April 2021.

Goal Attainment in an Individually Tailored and Home-Based Intervention in the Chronic Phase after Traumatic Brain Injury

Traumatic brain injury (TBI) is a heterogeneous condition with long-term consequences for individuals and families. Goal-oriented rehabilitation is often applied, but there is scarce knowledge regarding types of goals and goal attainment. This study describes goal attainment in persons in the chronic phase of TBI who have received an individualized, SMART goal-oriented and home-based intervention, compares goal attainment in different functional domains, and examines indicators of goal attainment. Goal attainment scaling (GAS) was recorded in the intervention group (n = 59) at the final session. The goal attainment was high, with 93.3% increased goal attainment across all goals at the final session. The level of goal attainment was comparable across domains (cognitive, physical/somatic, emotional, social). Gender, anxiety symptoms, self-reported executive dysfunction, and therapy expectations were indicators of goal attainment. These results indicate a potential for the high level of goal attainment in the chronic phase of TBI. Tailoring of rehabilitation to address individual needs for home-dwelling persons with TBI in the chronic phase represents an important area of future research.

Transitional care programs to improve outcomes in patients with traumatic brain injury and their caregivers: A systematic review and meta-analysis

Background

Effective nursing interventions for caring for patients with moderate to severe traumatic brain injury are still challenging during a transition from hospital to home. Since traumatic brain injury has deep-rooted sequelae, patients and their caregivers require better arrangement and information on the condition to achieve improved outcomes after discharge.

Objective

This study aimed to assess transitional care programs to improve outcomes of patients with traumatic brain injury and their caregivers.

Methods

A systematic review and meta-analysis were performed on studies retrieved from ProQuest, PubMed, Science Direct, CINAHL, and Google Scholar from January 2010 to July 2021. RevMan 5.4.1 software was used for meta-analysis.

Results

Nine studies were systematically selected from 1,137 studies. The standard approaches of interventions used in patients with traumatic brain injury and their caregivers were education, mentored problem-solving, home-and community-based rehabilitation, counseling, skill-building, and psychological support. We observed that there was significant evidence indicating beneficial effects of intervention in increasing the physical functioning of patients with traumatic brain injury (SMD = -0.44, 95% CI -0.60 to -0.28, p <0.001), reducing the psychological symptoms among caregivers (SMD = -0.42, 95% CI -0.59 to -0.24, p <0.001), and increasing the satisfaction (SMD = -0.35, 95% CI -0.60 to -0.11, p = 0.005).

Conclusion

Education, skill-building, and psychological support should be the main components in transitional care nursing programs for patients with traumatic brain injury and their caregivers.

Health, social care and technological interventions to improve functional ability of older adults living at home: An evidence and gap map

Background

By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value.

Objectives

This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence.

Search Methods

We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g., ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov).

Selection Criteria

Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps.

Data Collection and Analysis

We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist.

Main Results

After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality.The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication.There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues.

Authors' Conclusions

There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

Predicting caregiver burden over the first 4 months after acute traumatic brain injury in Latin America: a multi-country study

Background: Traumatic brain injury (TBI) rates and outcomes are worse in Latin American countries relative to high-income countries. This study examined whether cognitive dysfunction, depressive mood, and poor social and emotional self-regulation in individuals with an acute TBI in Latin America predict longitudinal trajectories of caregiver burden during the first 4 months post-discharge.Method: A sample of 109 caregivers of individuals with a new TBI from Colombia and Mexico completed the observer European Brain Injury Questionnaire before hospital discharge and the Zarit Burden Inventory at the same time and again at 2 and 4 months after discharge. A hierarchical linear model (HLM) was used to assess whether cognitive dysfunction, depressive mood, and poor social and emotional self-regulation at hospital discharge predicted longitudinal trajectories of caregiver burden.Results: Results suggested that burden trajectories decreased over time and men reported higher burden than women. Additionally, results showed that poor patient social and emotional self-regulation predicted higher burden trajectories.Conclusions: Men and caregivers providing care for those experiencing poor social and emotional self-regulation may be at risk for burden. Culturally sensitive interventions focusing on social functioning of individuals with TBI and gender-informed caregiver interventions aimed at burden should be implemented in Latin America.

The effectiveness of a family-centred intervention after traumatic brain injury: A pragmatic randomised controlled trial

Objectives:

To determine the effectiveness of a family-centred intervention for patients with traumatic brain injury and family members.

Design:

Open-labelled, two-armed randomised controlled trial.

Settings:

Outpatient clinic and family residences.

Participants:

Sixty-one patients (33 women) with traumatic brain injury, with mean (SD) age 43.8 (12.2), and 63 family members (33 women), with mean (SD) age 42.6 (11.3), were assign to intervention (n = 30 families) and control group (n = 31 families).

Intervention:

An eight-session single-family intervention to improve individual and family functioning.

Outcome measures:

Self-reported questionnaires at start-of-treatment, median (IQR) 11.4 (8.4, 15.9) months post-injury, and at two follow-ups, 2.7 (2.3, 3.8) and 9.2 (8.2, 9.9) months after start-of-treatment. Primary outcome measures were the SF-36 Mental Component Summary (MCS) and Caregiver Burden Scale (CGB). Secondary outcome measures were the Family Adaptability and Cohesion Evaluation Scale (FACES) and Quality of Life after Brain Injury Questionnaire (QOLIBRI). Group differences were analysed with linear mixed-model analysis for repeated measurements.

Results:

No significant between-group differences were found. The intervention group significantly improved on the MCS, the CGB and FACES in the treatment period, whereas the controls did not. The mean (SD) MCS change in the treatment period was 2.4 (1.1) points P = 0.028 in the intervention group. Mean (SE) MCS scores were 47.9 (1.26) and 47.3 (1.27) in the intervention and control group at last follow-up.

Conclusions:

Receiving an eight-session family intervention, in addition to specialised rehabilitation for the patients, was not superior to rehabilitation at a specialised traumatic brain injury outpatient clinic.

The additional burden of PTSD on functioning and depression in veterans with traumatic brain injury

BACKGROUND

Many United States veterans and active military with a history of traumatic brain injury (TBI) also experience challenges from comorbid posttraumatic stress disorder (PTSD), yet the additional burden of PTSD is not clear.

PURPOSE

To address this knowledge gap, this study examined the relationship of PTSD to cognitive, social, and physical functioning and depressive symptoms in veterans recently diagnosed with TBI.

METHODS

Veterans were recruited from a VA rehabilitation clinic. The Patient Competency Rating Scale and Center for Epidemiologic Studies Depression Scale measured functioning and depression, respectively. Chart review captured PTSD diagnosis.

FINDINGS

In the sample of 83 veterans, 65% had a current PTSD diagnosis. After controlling for sociodemographic variables and TBI severity, PTSD was a significant predictor of lower cognitive, social, and physical functioning and higher depressive symptomatology.

DISCUSSION

Clinicians should incorporate PTSD assessment in their work with veterans with TBI. Integrated behavioral health and rehabilitation interventions that provide strategies for veterans to manage TBI symptoms and PTSD are critical.

Effectiveness of Combining Compensatory Cognitive Training and Vocational Intervention vs. Treatment as Usual on Return to Work Following Mild-to-Moderate Traumatic Brain Injury: Interim Analysis at 3 and 6 Month Follow-Up

Aims: Knowledge regarding the most effective return to work (RTW) approaches after traumatic brain injury (TBI) is lacking. This trial aimed to compare the effectiveness of a combined cognitive and vocational intervention to treatment as usual (TAU) on RTW and work stability after TBI.

Methods: We performed a parallel-group randomized controlled trial (RCT) at a TBI outpatient clinic at Oslo University Hospital (OUH), Norway. Patients with a history of mild-to-moderate TBI (n = 116) aged 18–60 were randomized (1:1) by an independent investigator to receive group-based compensatory cognitive training (CCT) and supported employment (SE) (n = 60) or TAU consisting of individualized multidisciplinary treatment (n = 56). Participants were enrolled 2–3 months post-injury. The nature of the intervention prevented blinding of patients and therapists, however, outcome assessors were blinded to group allocation. The primary outcome measure was RTW at 3 and 6 months following study inclusion. Secondary outcomes were work percentage, stability, and productivity. The present study provides results from an interim analysis from the first two planned follow ups, while subsequent publications will present results up to 12 months following study inclusion.

Results: Mixed effects models showed no between-group differences in the RTW proportion, work percentage, and hours worked between CCT-SE and TAU from baseline to 6 months. A significantly higher proportion of participants in CCT-SE had returned to work at 3 months when adjusting for baseline differences. The majority of participants who were employed at 3 and 6 months were stably employed. There was a statistically significant within-group improvement on RTW proportion, hours worked and work percentage in both groups.

Conclusion: The results revealed no difference between CCT-SE and TAU on work-related outcomes from baseline to 6 months. However, there was a higher RTW proportion in the CCT-SE group compared to TAU at 3 months. Future publications will assess the effectiveness of CCT-SE vs. TAU up to 12 months.

Effect of an in-home, family-inclusive rehabilitation programme on depressive symptoms in veterans with traumatic brain injury and its mediation by activity engagement

Background/Aims

Depression, the most common psychiatric sequela of traumatic brain injury in both civilians and veterans, produces serious and wide-ranging problems. Although medication and cognitive behavioural therapy are the most common treatments, some rehabilitation approaches designed to enhance functioning and/or community reintegration may decrease depression by facilitating active engagement in life – the key component of some depression therapies. The present secondary analysis of a community reintegration-focused rehabilitation programme for veterans with traumatic brain injury posed two questions: Did the programme affect depressive symptoms? If so, was this effect mediated by engagement in activities?

Methods

A secondary analysis was undertaken of an intervention study of 83 former members of the United States Armed Forces (veterans) with traumatic brain injury, who were interviewed in their homes. Depressive symptoms were assessed using the short-form Centre for Epidemiological Studies-Depression Scale, activity engagement using an 8-item subscale derived from the Community Reintegration of Injured Service Members Scale, and physical and emotional functioning using the SF-36V. Sociodemographic, medical and military characteristics were elicited during the first interview, and medical and military characteristics were identified through a medical chart review.

Results

Depressive symptoms significantly decreased among the veterans in the treatment group. That effect was mediated by activity engagement. Thus, the intervention's impact on depressive symptoms was attributable to the increased activity that it produced.

Conclusions

Research on rehabilitation that enhances engagement in activities should examine its possible benefits for improving mood.

Traumatic brain injury-needs and treatment options in the chronic phase: Study protocol for a randomized controlled community-based intervention

BACKGROUND

Traumatic brain injury (TBI) is often associated with life-long medical, cognitive, emotional, and behavioral changes. Although long-lasting disabilities are expected, research on effective treatment options in the chronic phase of TBI is scarce.

METHODS/DESIGN

This study protocol describes a randomized controlled trial (RCT) aimed at evaluating the effectiveness of a goal-oriented and community-based intervention for increasing community integration, quality of life, and functional independence in the chronic phase of complicated mild to severe TBI. Participants will be recruited from Oslo University Hospital, Norway. Patients aged 18-72 years living at home with MRI/CT-verified intracranial abnormalities, a TBI diagnosis, a time since injury of ≥ 2 years, and who experience either current TBI-related problems or restrictions in community integration will be included. The 120 participants will be randomized 1:1 to either (a) an intervention group, which will receive an in-home intervention program over 4 months, or (b) a control group receiving standard care in the municipalities. The intervention will consist of six home visits and two telephone contacts with a rehabilitation professional. A SMART-goal approach will be adopted to target the individual's self-reported TBI difficulties in everyday life. Primary outcomes will be self-reported quality of life and participation. Secondary outcomes include symptom burden, emotional functioning, and clinician-assessed global outcome and need for rehabilitation services. Outcomes will be evaluated at baseline and 4-5 and 12 months after baseline. Caregiver burden and general health will be assessed in participating family members. Goal attainment and acceptability will be evaluated in the intervention group. A process evaluation will be carried out to evaluate protocol adherence, and a cost-effectiveness analysis will be applied if the intervention is found to be effective.

DISCUSSION

The current study provides an innovative approach to rehabilitation in the chronic phase of TBI evaluated using an RCT design that may inform treatment planning, health policies, and coordination of patient care. Further, the study may demonstrate new modes of establishing collaboration and knowledge transition between specialized rehabilitation facilities and local rehabilitation services that may improve patient outcomes.

Randomized Controlled Trials of Rehabilitation Services in the Post-acute Phase of Moderate and Severe Traumatic Brain Injury - A Systematic Review

Background and aims: There is a gap in knowledge regarding effective rehabilitation service delivery in the post-acute phase after traumatic brain injury (TBI). Recently, Gutenbrunner et al. proposed a classification system for health-related rehabilitation services (International Classification System for Service Organization in Health-related Rehabilitation, ICSO-R) that could be useful for contrasting and comparing rehabilitation services. The ICSO-R describes the dimensions of Provision (i.e., context of delivered services), Funding (i.e., sources of income and refunding), and Delivery (i.e., mode, structure and intensity) at the meso-level of services.

We aim to:

-Provide an overview of randomized, controlled trials (RCTs) with rehabilitation service relevance provided to patients with moderate and severe TBI in the post-acute phase using the ICSO-R as a framework; and

-Evaluate the extent to which the provision, funding and delivery dimensions of rehabilitation services were addressed and differed between the intervention arms in these studies.

Materials and methods: A systematic literature search was performed in OVID MEDLINE, EMBASE, CINHAL, PsychINFO, and CENTRAL, including multidisciplinary rehabilitation interventions with RCT designs and service relevance targeting moderate and severe TBI in the post-acute phase.

Results: 23 studies with 4,644 TBI patients were included. More than two-thirds of the studies were conducted in a hospital-based rehabilitation setting. The contrast in Context between the intervention arms often co-varied with Resources. The funding of the services was explicitly described in only one study. Aspects of the Delivery dimension were described in all of the studies, and the Mode of Production, Intensity, Aspects of Time and Peer Support were contrasted in the intervention arms in several of the studies. A wide variety of outcome measures were applied often covering Body function, as well as the Activities and Participation domains of the International Classification of Functioning, Disability, and Health (ICF).

Conclusion: Aspects of service organization and resources as well as delivery may clearly influence outcome of rehabilitation. Presently, lack of uniformity of data and collection methods, the heterogeneity of structures and processes of rehabilitation services, and a lack of common outcome measurements make comparisons between the studies difficult. Standardized descriptions of services by ICSO-R, offer the possibility to improve comparability in the future and thus enhance the relevance of rehabilitation studies.

Employment Status Among U.S. Military Veterans With Traumatic Brain Injury: Mediation Analyses and the Goal of Tertiary Prevention

For most individuals with traumatic brain injury (TBI), the ability to work is crucial to financial and psychological well-being. TBI produces a wide range of cognitive, physical, emotional, and interpersonal impairments that may undermine the ability to work. Employment is therefore a primary goal of TBI rehabilitation and has been the focus of extensive research. Although this literature has identified predictors of employment outcomes, few studies have examined the mechanisms that underlie these associations. Mediation analysis can identify these mechanisms, provide a more nuanced view of how predictors jointly affect rehabilitation outcomes, and identify predictors that, if treatable conditions, could be useful targets for tertiary prevention. Such efforts are aimed at reducing long-term impairments, disability, or suffering resulting from the injury. The study sample comprised 83 U.S. military veterans with TBI who had participated in a larger rehabilitation study and were interviewed in their homes. Bivariate tests revealed significant associations of employment with pain, cognitive functioning, self-rated health, depressive symptoms and physical functioning; the latter variable was operationalized in two ways—using the Patient Competency Rating Scale and the SF–36V physical functioning subscales. Because these physical functioning measures were highly intercorrelated (r = 0.69, p < 0.0001), separate regression models were conducted. In the hierarchical binary logistic regression models, predictors were entered in order of modifiability, with comorbidities (pain) entered in block 1, physical health/functioning sequelae in block 2, and depressive symptoms in block 3. In the regression using the SF-36V measure of physical functioning, pain's effect was mediated by the physical functioning/health predictors, with only physical functioning emerging as significant, but this effect was itself mediated by depressive symptoms. In the regression using the PCRS physical-function measure, only depressive symptoms emerged as a mediator of other effects. Findings underscore the central role of depression in the employment status of veterans with TBI, suggesting that negative effects of other problems/limitations could be mitigated by more effective treatment of depression. Thus, for many with chronic TBI who live with vocational limitations, outcomes may improve with lower depression. Findings argue for the wider use of mediation approaches in TBI research as a means of identifying targets for tertiary prevention of poor outcomes.

Traumatic brain injury education for adult patients and families: a scoping review

Traumatic brain injury (TBI) is increasingly viewed as a chronic condition, bringing long-term needs for patient and caregiver knowledge pertaining to symptom and problem management over time. In light of these needs, we performed a scoping review of the literature on brain injury education provided to adult patients and/ or family members affected by TBI. Objectives were to describe the types of educational interventions that have been developed; to review the effects of these interventions; and to determine gaps that might be filled by future research efforts. Of 88 articles meeting search criteria and subjected to data extraction, 34 concerned education about mild TBI and 54, moderate to severe TBI. Most mild TBI articles focused on education in the Emergency Room, while most moderate/ severe TBI education was directed toward family members/ caregivers and was frequently combined with other treatment components, making the effects of education difficult to discern. Only 1 article incorporated elements of self-management training (SMT), a model proved effective in other chronic health conditions. We recommend further exploration of SMT principles in long-term TBI care, as well as more precise definition of treatment components in all patient and family interventions, so that the specific effects of education and other treatment elements may be more readily evaluated.

Interventions That Support or Involve Caregivers or Families of Patients with Traumatic Injury: a Systematic Review

BACKGROUND

Almost 40 million family caregivers care for a loved one with severe physical or cognitive impairments. The purpose of this review is to summarize evidence about the benefits of interventions to support or involve family members/caregivers of patients with trauma-related injury on caregiver, patient, and household outcomes.

METHODS

English-language peer-reviewed publications in MEDLINE, CINAHL, and PsycINFO from 1995 through December 2016 were identified. Eligible studies included RCT or quasi-experimental studies evaluating interventions designed to support or involve caregivers or family members of patients with TBI, PTSD, or polytrauma. Abstractions were completed by one reviewer and checked by a second; two reviewers independently assessed risk of bias using the Cochrane Effective Practice and Organization of Care Review Criteria.

RESULTS

Thirteen studies (n = 9 TBI; n = 4 PTSD, n = 0 polytrauma) evaluated psychological or rehabilitation interventions involving caregivers. Interventions did not improve TBI patients' functional status (standardized mean difference [SMD], 0.29 [95% confidence interval [CI], - 0.51 to 1.08]) or psychological symptoms (SMD - 0.25, CI - 0.62 to 0.12). Qualitative analysis shows potential intervention benefit for TBI symptoms. Interventions did not improve TBI caregiver psychological symptoms (SMD - 0.26, CI - 0.57 to 0.05); however, qualitative analysis suggests mixed effects for caregiver burden and quality of life. Positive intervention effects on patients' PTSD symptoms, mental health service use, and PTSD caregivers' psychological symptoms were identified with certain interventions. Strength of evidence ranged from moderate to very low.

DISCUSSION

Studies showed mixed patterns of intervention effects on caregiver and patient outcomes; evidence about intervention impact is inconclusive. This review is the first to identify caregiving interventions for patients with TBI and polytrauma and extends past reviews about patients with PTSD. Limitations include a small evidence base, low study quality, disparate methods, varied outcome measures, and high heterogeneity. PROSPERO Registration CRD42017053516.

Exploration of Factors Related to Depressive Symptomatology in Family Members of Military Veterans With Traumatic Brain Injury

Traumatic brain injury (TBI) is a family affair, affecting those with the injury and their families. Psychological distress, often measured as depression or depressive symptoms, is highly prevalent among family members. Predictors of depression in family members of civilians with TBI have been examined, but predictors of depression in family members of military veterans have received very little research attention and are poorly understood. To address the knowledge gap, this study explored factors related to depressive symptoms in family members of veterans in the United States, using an ecological framework. Baseline data from 83 family members were used. Family members with higher caregiver burden, presence of a veteran with posttraumatic stress disorder (PTSD), and greater financial difficulty experienced significantly more depressive symptoms. Findings suggest that efforts to support family members and decrease their depression should aim to reduce caregiver burden and financial difficulty, and help family members cope with veteran PTSD and TBI. Family-focused interventions are needed.

Connecting the Brain to Itself through an Emulation

Pilot clinical trials of human patients implanted with devices that can chronically record and stimulate ensembles of hundreds to thousands of individual neurons offer the possibility of expanding the substrate of cognition. Parallel trains of firing rate activity can be delivered in real-time to an array of intermediate external modules that in turn can trigger parallel trains of stimulation back into the brain. These modules may be built in software, VLSI firmware, or biological tissue as in vitro culture preparations or in vivo ectopic construct organoids. Arrays of modules can be constructed as early stage whole brain emulators, following canonical intra- and inter-regional circuits. By using machine learning algorithms and classic tasks known to activate quasi-orthogonal functional connectivity patterns, bedside testing can rapidly identify ensemble tuning properties and in turn cycle through a sequence of external module architectures to explore which can causatively alter perception and behavior. Whole brain emulation both (1) serves to augment human neural function, compensating for disease and injury as an auxiliary parallel system, and (2) has its independent operation bootstrapped by a human-in-the-loop to identify optimal micro- and macro-architectures, update synaptic weights, and entrain behaviors. In this manner, closed-loop brain-computer interface pilot clinical trials can advance strong artificial intelligence development and forge new therapies to restore independence in children and adults with neurological conditions.

Self-Reported Driving Difficulty in Veterans With Traumatic Brain Injury: Its Central Role in Psychological Well-Being

BACKGROUND

The ability to drive is a core function supporting independent living. Traumatic brain injury (TBI) may impair driving capacity in numerous ways. Previous research has documented that individuals with TBI have more driving-related problems than other people and has identified predictors of driving status or capacity, mostly among civilians; however, no research has examined the implications of driving limitations for the well-being of individuals with TBI.

OBJECTIVE

To examine the association between self-reported difficulty in driving with important domains of psychological well-being in veterans with TBI, with adjustment for posttraumatic stress disorder (PTSD) and years since most recent TBI.

DESIGN

Cross-sectional.

SETTING

Veterans' homes.

PARTICIPANTS

A total of 61 veterans of the Global Wars on Terrorism diagnosed with TBI, all outpatients at a Veterans Affairs medical center rehabilitation service.

METHODS

Home interviews as a baseline assessment for a larger randomized controlled trial.

MAIN OUTCOME MEASURES

Community reintegration (extent of social participation), depressive symptomatology, and role limitations due to physical health problems and those due to emotional problems. Self-rated competence in driving was the predictor, and sociodemographic characteristics, diagnosis of PTSD, severity of TBI, and time since most recent TBI were covariates.

RESULTS

Self-rated driving difficulty was associated with decreased community reintegration (β = .280, P =.028), greater depressive symptomatology (β = -.402, P < .001), and greater role limitations due to physical problems (β = -.312, P =.011) and to emotional problems (β = -.324, P = .006), after we adjusted for PTSD and other variables.

DISCUSSION

The self-reported ability to drive seems to be central to psychological well-being in veterans with TBI, showing clear associations with depression, community reintegration, and health-related role limitations. These associations cannot be attributed to comorbid PTSD.

CONCLUSION

Rehabilitation specialists should view driving difficulty as a risk factor for poor psychosocial outcomes in veterans with TBI and seek ways to compensate for the veteran's loss of driving if it is no longer advisable.

Rating functional capabilities of veterans with traumatic brain injury by family members and veterans

Background/Aims:

People with a traumatic brain injury often perceive their everyday functional capabilities differently from their families. The tendency to underrate one's own limitations is often attributed to deficits in self-awareness. Yet the possibility that family ratings are subjective and may thus account for differences has been neglected despite its clinical relevance. The present study examined possible factors influencing family member's ratings, testing two hypotheses: (1) Different types of relatives (i.e. spouses versus non-spouses) may rate functioning differently (2) Incongruence may be more pronounced in less observable domains of function.

Methods:

In a cross-sectional study, 83 veterans with a traumatic brain injury and a non-spousal family member or spouse were interviewed at home, using the Patient Competency Rating Scale and eliciting sociodemographic characteristics.

Findings:

Competence ratings differed by relationship type (spouse/other), with spouses rating veteran functioning lower (mean: 3.25, SD=0.762) than did non-spouses overall (mean: 3.55, SD=0.583; F [1, 81]=4.55, P=0.036). Incongruent ratings by veterans and family members (across relationship types) were found in the domain of cognitive functioning only (F [1, 81]=4.268, P=0.042).

Conclusions:

Treatment plans should not rely exclusively on family ratings of functional competence. Non-spousal family members in particular may underestimate functional difficulties, especially in the cognitive domain.
