Return to work following traumatic brain injury: Trends and challenges

Cognitive vulnerabilities and depressed mood in acquired brain injury

ABSTRACTAcquired Brain Injury (ABI), an important cause of long-term disability, is associated with increased rates of depression in addition to common cognitive and physical consequences. Past research has linked post-ABI depression to injury severity (e.g., extent of physical or cognitive impairment) and premorbid mood problems. In the general (non-ABI) population, depression is associated with cognitive vulnerabilities that have informed the development of psychological interventions. In this observational study in a heterogeneous sample of individuals with chronic stage ABI, we examine two cognitive vulnerabilities - dysfunctional attitudes (DAs) and autobiographical memory specificity - and explore whether these are linked to depression symptoms and ongoing cognitive difficulties as in the general population. Compared to control participants, individuals with an ABI demonstrated increased endorsement of DAs and reduced specificity of autobiographical memory recall. Within the ABI group, cognitive vulnerability-depression symptom correlations were detected for an explicit measure of DAs, but not for a more implicit DA measure or for autobiographical memory specificity. While individual differences in injury severity and other factors likely obscured subtle relationships between mood and cognitive vulnerabilities, evidence of these vulnerabilities may be relevant to changes in identity and psychological interventions that target low mood in ABI.

A framework to support early team-based provision of vocational rehabilitation for adults with acquired brain injury

PURPOSE

Specialised vocational rehabilitation (VR) following acquired brain injury (ABI) positively impacts return to work, however access to this is limited globally. Providing VR as a component of standard ABI rehabilitation may improve access to VR and influence vocational outcomes. This study aimed to develop an evidence-based framework for the delivery of ABI VR during early transitional community rehabilitation.

MATERIALS AND METHODS

The development of the ABI VR framework utilised an emergent multi-phase design and was informed by models of evidence-based practice, national rehabilitation standards, guidelines for complex intervention development, model of care and framework development, and the knowledge-to-action framework. Four study phases were undertaken to identify and generate the evidence base, with findings synthesised to develop the ABI VR framework in phase five.

RESULTS

The framework provides a structure for the systematic delivery of VR as a component of team-based ABI rehabilitation, through five phases of rehabilitation: assessment; goal setting and rehabilitation planning; intervention; monitoring and evaluation; and discharge. It details the activities to be undertaken across the phases using a hybrid model of ABI VR (involving program-based VR and case coordination) and contains service delivery features.

CONCLUSION

The framework has the potential to translate to other similar service contexts.

The contribution of executive functions to the process of return to work after brain injury: A systematic review

Acquired brain injury (ABI) is a worldwide public health issue for its high prevalence rate and the disability it produces. The consequences of ABI, including cognitive deficits, may impact return to work. This review focuses on the association between executive functions (EFs) and return to work after ABI. A systematic review of the literature between 1998 and 2023 was conducted following PRISMA guidelines. The articles were retrieved from the Pubmed, Medline and Web of Science databases. A total of 49 studies were finally selected. Impairments of EF were consistently shown to have a negative impact on return to work after an ABI. There is evidence that specific executive functions and neurobehavioral variables may affect return to work Studies showed a significant theoretical and methodological heterogeneity, representing an important limitation to understand the relation between EFs and work. There is a robust association between EFs and return to work after brain injury. Findings in this systematic review raise the need for further research on the role of specific EF profiles in the process of returning to work after brain damage.

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.

Assessment of impaired self-awareness after moderate-to-severe traumatic brain injury: a comparison of assessment tools

OBJECTIVE

To compare different assessment methods of impaired self-awareness (ISA).

METHODS

We included 37 patients with moderate-to-severe traumatic brain injury (TBI) at a subacute/chronic stage, and 33 healthy controls. ISA was assessed with three methods: discrepancy scores (comparison between patient and proxy ratings) on three scales (Patient Competency Rating Scale (PCRS), Awareness Questionnaire (AQ) and Dysexecutive Questionnaire (DEX)); clinician rating with the Self-Awareness of Deficits Interview (SADI); and the difference between prediction or estimation of performance and actual performance on two cognitive tasks.

RESULTS

Clinician-patient discrepancy scores appeared more sensitive than relative-patient discrepancy. The AQ was the most sensitive. The discrepancy scores were strongly correlated one with each other. Correlations with the SADI were weaker. Patients did not overestimate their performance on cognitive tasks, and the prediction did not significantly correlate with other measures of ISA.

DISCUSSION/CONCLUSION

Results support the multidimensional nature of ISA: discrepancy scores assess meta-cognitive knowledge (understanding that a function/skill is affected), while the SADI takes into account anticipatory awareness (ability to set realistic goals) and estimation of performance assesses anticipatory and situational awareness. Assessment of these different domains may provide a comprehensive overview of an individual's self-awareness.

Exploring Discussions About Virtual Reality on Twitter to Inform Brain Injury Rehabilitation: Content and Network Analysis

BACKGROUND

Virtual reality (VR) use in brain injury rehabilitation is emerging. Recommendations for VR development in this field encourage end user engagement to determine the benefits and challenges of VR use; however, existing literature on this topic is limited. Data from social networking sites such as Twitter may further inform development and clinical practice related to the use of VR in brain injury rehabilitation.

OBJECTIVE

This study collected and analyzed VR-related tweets to (1) explore the VR tweeting community to determine topics of conversation and network connections, (2) understand user opinions and experiences of VR, and (3) identify tweets related to VR use in health care and brain injury rehabilitation.

METHODS

Publicly available tweets containing the hashtags #virtualreality and #VR were collected up to twice weekly during a 6-week period from July 2020 to August 2020 using NCapture (QSR International). The included tweets were analyzed using mixed methods. All tweets were coded using inductive content analysis. Relevant tweets (ie, coded as "VR in health care" or "talking about VR") were further analyzed using Dann's content coding. The biographies of users who sent relevant tweets were examined descriptively. Tweet data networks were visualized using Gephi computational analysis.

RESULTS

A total of 260,715 tweets were collected, and 70,051 (26.87%) were analyzed following eligibility screening. The sample comprised 33.68% (23,596/70,051) original tweets and 66.32% (46,455/70,051) retweets. Content analysis generated 10 main categories of original tweets related to VR (ie, advertising and promotion, VR content, talking about VR, VR news, general technology, VR industry, VR live streams, VR in health care, VR events, and VR community). Approximately 4.48% (1056/23,596) of original tweets were related to VR use in health care, whereas 0.19% (45/23,596) referred to VR in brain injury rehabilitation. In total, 14.86% (3506/23,596) of original tweets featured commentary on user opinions and experiences of VR applications, equipment, and software. The VR tweeting community comprised a large network of 26,001 unique Twitter users. Users that posted tweets related to "VR in health care" (2124/26,001, 8.17%) did not form an interconnected VR network, whereas many users "talking about VR" (3752/26,001, 14.43%) were connected within a central network.

CONCLUSIONS

This study provides valuable data on community-based experiences and opinions related to VR. Tweets showcased various VR applications, including in health care, and identified important user-based considerations that can be used to inform VR use in brain injury rehabilitation (eg, technical design, accessibility, and VR sickness). Limited discussions and small user networks related to VR in brain injury rehabilitation reflect the paucity of literature on this topic and the potential underuse of this technology. These findings emphasize that further research is required to understand the specific needs and perspectives of people with brain injuries and clinicians regarding VR use in rehabilitation.

Intelligence and executive function are associated with age at insult, time post-insult, and disability following chronic pediatric acquired brain injury

Background

Pediatric acquired brain injury (pABI) profoundly affects cognitive functions, encompassing IQ and executive functions (EFs). Particularly, young age at insult may lead to persistent and debilitating deficits, affecting daily-life functioning negatively. This study delves into the intricate interplay of age at insult, time post-insult, and their associations with IQ and EFs during chronic (>1 year) pABI. Additionally, we investigate cognitive performance across different levels of global function, recognizing the multifaceted nature of developmental factors influencing outcomes.

Methods

Drawing upon insult data and baseline information analyzing secondary outcomes from a multicenter RCT, including comprehensive medical and neuropsychological assessments of participants aged 10 to 17 years with pABI and parent-reported executive dysfunctions. The study examined associations between age at insult (early, EI; ≤7y vs. late, LI; > 7y) and time post-insult with IQ and EFs (updating, shifting, inhibition, and executive attention). Additionally, utilizing the Pediatric Glasgow Outcome Scale-Extended, we explored cognitive performance across levels of global functioning.

Results

Seventy-six participants, median 8 years at insult and 5 years post-insult, predominantly exhibiting moderate disability (n = 38), were included. Notably, participants with LI demonstrated superior IQ, executive attention, and shifting compared to EI, [adjusted mean differences with 95% Confidence Intervals (CIs); 7.9 (1.4, 14.4), 2.48 (0.71, 4.24) and 1.73 (0.03, 3.43), respectively]. Conversely, extended post-insult duration was associated with diminished performances, evident in mean differences with 95% CIs for IQ, updating, shifting, and executive attention compared to 1-2 years post-insult [-11.1 (-20.4, -1.7), -8.4 (-16.7, -0.1), -2.6 (-4.4, -0.7), -2.9 (-4.5, -1.2), -3.8 (-6.4, -1.3), -2.6 (-5.0, -0.3), and -3.2 (-5.7, -0.8)]. Global function exhibited a robust relationship with IQ and EFs.

Conclusion

Early insults and prolonged post-insult durations impose lasting tribulations in chronic pABI. While confirmation through larger studies is needed, these findings carry clinical implications, underscoring the importance of vigilance regarding early insults. Moreover, they dispel the notion that children fully recover from pABI; instead, they advocate equitable rehabilitation offerings for pABI, tailored to address cognitive functions, recognizing their pivotal role in achieving independence and participation in society. Incorporating disability screening in long-term follow-up assessments may prove beneficial.

The impact of minimum unit pricing on traumatic brain injury in Scotland: a retrospective cohort study of routine national data

BACKGROUND

Traumatic brain injury (TBI) is a common cause of disability and mortality and is associated with alcohol consumption. On 1st May 2018, the Scottish Government introduced Minimum Unit Pricing (MUP) legislation which set the floor price at which alcohol can be sold to 50 pence per unit. While MUP has led to a 7.6% decrease in off trade alcohol purchases, there are limited studies investigating the clinical impact of this legislation. This study aims to explore the impact of MUP on traumatic brain injury in Scotland.

METHODS

Retrospective cohort study using routinely collected national data collated by the Scottish Trauma Audit Group. Data were requested for all TBI incidents from 1st May to 31st December for both 2017 and 2018. Primary outcome was alcohol-related TBI. Secondary outcomes were injury mechanism, injury severity, clinical course, and short-term mortality. Analysis was conducted using multiple regression models adjusted for age, sex, season, and deprivation.

RESULTS

A total of 1166 patients (66% male, and 46% in the 60-79-year bracket) were identified. Alcohol-related TBI was evident in 184 of 509 (36%) patients before MUP and in 239 of 657 (36%) patients injured after its implementation (p = 0.638). Further, there was no change in injury mechanism, injury severity, hospital course and short-term mortality of TBI after MUP.

CONCLUSIONS

MUP has not resulted in a change in alcohol-related TBI nor in the mechanism and severity of TBI. Limitations in two-point analysis mean that findings should be interpreted with caution and further studies investigating the clinical outcomes of MUP must be conducted.

Predicting return to work after traumatic brain injury using machine learning and administrative data

BACKGROUND

Accurate patient-specific predictions on return-to-work after traumatic brain injury (TBI) can support both clinical practice and policymaking. The use of machine learning on large administrative data provides interesting opportunities to create such prognostic models.

AIM

The current study assesses whether return-to-work one year after TBI can be predicted accurately from administrative data. Additionally, this study explores how model performance and feature importance change depending on whether a distinction is made between mild and moderate-to-severe TBI.

METHODS

This study used a population-based dataset that combined discharge, claims and social security data of patients hospitalized with a TBI in Belgium during the year 2016. The prediction of TBI was attempted with three algorithms, elastic net logistic regression, random forest and gradient boosting and compared in their performance by their accuracy, sensitivity, specificity and area under the receiver operator curve (ROC AUC).

RESULTS

The distinct modelling algorithms resulted in similar results, with 83% accuracy (ROC AUC 85%) for a binary classification of employed vs. not employed and up to 76% (ROC AUC 82%) for a multiclass operationalization of employment outcome. Modelling mild and moderate-to-severe TBI separately did not result in considerable differences in model performance and feature importance. The features of main importance for return-to-work prediction were related to pre-injury employment.

DISCUSSION

While clearly offering some information beneficial for predicting return-to-work, administrative data needs to be supplemented with additional information to allow further improvement of patient-specific prognose.

Clinician perspectives of ABI vocational rehabilitation in Queensland

INTRODUCTION

Services to support adults with acquired brain injury (ABI) and return to work goals are varied. In Queensland, Australia, return to work goals may be addressed through private or publicly funded rehabilitation services or through publicly funded employment programs. No set frameworks or processes are in place to guide clinicians in providing vocational rehabilitation to adults with ABI, and the extent to which services address clients' vocational goals and/or provide vocational rehabilitation is unknown.

METHOD

This qualitative study investigated the clinical practice and experiences of allied health rehabilitation clinicians (n = 34) to identify current practice in providing vocational rehabilitation to adults with ABI, including pathways and services; models, frameworks and tools; and recommendations for ideal services. Focus groups and online surveys were conducted, with data analysed via content analysis.

RESULTS

ABI vocational rehabilitation was inconsistently delivered within and across services in Queensland, with differences in access to services, aspects of vocational rehabilitation provided and timeframes for rehabilitation. Five key themes were identified regarding ABI vocational rehabilitation and service delivery in Queensland: Factors influencing ABI and return to work; Service provision; ABI vocational rehabilitation processes (including assessment tools and interventions); Service gaps; and Ideal ABI vocational rehabilitation services.

DISCUSSION

These findings can inform clinical practice and development, and current and future service delivery models for ABI vocational rehabilitation.

Long-Term Vocational Outcome at 15 Years from Severe Traumatic and Non-Traumatic Brain Injury in Pediatric Age

BACKGROUND

Recent studies suggest that acquired brain injury with impaired consciousness in infancy is related to more severe and persistent effects and may have a cumulative effect on ongoing development. In this work, we aim to describe vocational outcome in a group of patients at 15 years from a severe brain lesion they suffered in developmental age.

METHODS

This study included a total of 147 patients aged 1.5 to 14 years with acquired brain lesion. Clinical and functional details ("Glasgow Outcome Scale", "Functional Independent Measure" and Intelligence Quotient) were collected at the time of their first hospitalization and vocational outcome was determined after 15 years.

RESULTS

94 patients (63.9%) presented with traumatic brain injury, while 53 patients (36.1%) presented with a brain lesion of other origin. Traumatic patients had a higher probability of being partly or fully productive than non-traumatic ones: 75.5% of traumatic subjects were working-taking into account limitations due to the traumatic event-versus 62.3% of non-traumatic ones. A relationship between some clinical variables and the vocational outcome was found.

CONCLUSIONS

Rehabilitation should adequately emphasize "vocational rehabilitation" because a significant proportion of people experiencing a disorder of consciousness in childhood may show good social integration in adult age.

Predictors of Social Participation Outcome after Traumatic Brain Injury Differ According to Rehabilitation Pathways

Social participation (SP) is one of many objectives in the rehabilitation of patients with traumatic brain injury (TBI). Studies on predictors of SP specific to post-acute universally accessible specialized rehabilitation pathways following TBI are scarce. Our objectives were to: 1) characterize SP, as well as a set of pre-injury, injury-related, and post-injury variables in individuals participating in inpatient-outpatient or outpatient rehabilitation pathways within a universally accessible and organized trauma continuum of care; and 2) examine the ability of pre-injury, injury-related, and post-injury variables in predicting SP outcome after TBI according to rehabilitation path. Participants (N = 372) were adults admitted to an inpatient-outpatient rehabilitation pathway or an outpatient rehabilitation pathway after sustaining a TBI between 2016 and 2020, and for whom Mayo-Portland Adaptability Intentory-4 (MPAI-4) outcomes were prospectively obtained at the start and end of rehabilitation. Additional data was collected from medical files. For both rehabilitation pathways, predicted SP outcome was MPAI-4 Participation score at discharge from outpatient rehabilitation. Multiple regression models investigated the predictive value of each variable for SP outcome, separately for each care pathway. Main findings show that for the inpatient-outpatient sample, three variables (education years, MPAI-4 Ability and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 49% of the variance. For the outpatient sample, five variables (pre-morbid hypertension and mental health diagnosis, total indirect rehabilitation hours received, MPAI-4 Abilities and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 47% of the variance. In conclusion, different pre-morbid and post-injury variables are involved in predicting SP, depending on the rehabilitation path followed. The predictive value of those variables could help clinicians identify patients more likely of showing poorer SP at discharge and who may require additional or different interventions.

Return to work following mild traumatic brain injury: Psychological and cognitive factors in a litigating sample in the post acute stage of recovery

The purpose of this study was to investigate return to work (RTW) rates following a single uncomplicated mild Traumatic Brain Injury (mTBI) in the post-acute stage in the context of active litigation. More specifically, we sought to determine what psychological and/or cognitive factors predict a RTW after mTBI. Archival data were obtained from a random sample of litigating patients (n = 125; 54% female; mean age: 42.96 (SD = 12.74) who were referred to a private practice for a neuropsychological examination regarding their disability status following a single uncomplicated mTBI. A hierarchical regression analysis was used to assess the predictive value of emotional symptoms and cognition with respect to RTW status. Approximately 50% of the sample did not RTW. Attentional deficits (rs = -0.248) and depressive symptoms (rs = 0.248) were significantly associated with RTW. A hierarchical regression analysis found that depressive symptoms (p < .05) were associated with RTW outcomes. These findings suggest that individuals with increased depressive symptoms are more likely to demonstrate poor RTW outcomes in the post-acute stages of mTBI. These results are of interest to clinicians as they underscore the importance of screening and early intervention for depressive symptoms following a single uncomplicated mTBI in the post-acute stages in litigating samples.

Use of item response theory to develop a return to work measure for acquired brain injury: The employment feasibility checklist

BACKGROUND

The 2001 Feasibility Evaluation Checklist (FEC) is an assessment of work readiness for individuals with acquired brain injury (ABI). It establishes the integrity of basic safety, productivity, and interpersonal factors in neurorehabilitation and vocational settings. This study represents an effort to further develop the FEC to increase its clinical utility.

OBJECTIVE

To redesign the FEC by conducting Item Response Theory (IRT) analyses on the study's results and combining those mathematical calibrations with clinical expert judgement. The result will be a new measure for use in clinical ABI neurorehabilitation and vocational settings: the Employment Feasibility Checklist (EFC).

METHODS

Seven participants with ABI were administered a situational assessment on multiple occasions by occupational therapists in a community rehabilitation clinic. The FEC was used to assess the participant's performance across three areas of basic employment feasibility: safety, productivity, and interpersonal factors. Results were analyzed with IRT-Rasch analysis and then subjected to clinical expert judgment, resulting in adjustment recommendations for the FEC.

RESULTS

In this scale development study, IRT analysis of results from 89 observation trials was combined with expert clinical judgment resulting in a redesigned tool with increased clinical utility for persons with ABI. The EFC is a 12-item observational rating scale for employment feasibility constructs of Productivity and Interpersonal Relations, with an additional six-item Workplace Safety subsection.

CONCLUSION

The EFC is a mathematically calibrated tool designed to gauge feasibility for competitive employment in clients with ABI. The tool may be useful in clinical neurorehabilitation settings and vocational rehabilitation settings.

Workplace Factors Associated With Return to Work After Mild-to-Moderate Traumatic Brain Injury

OBJECTIVE

Sociodemographic and injury-related predictors for return to work (RTW) after mild-to-moderate traumatic brain injury (TBI) have been extensively explored. However, there is a knowledge gap regarding work-related predictors of RTW. The main aim of this study was to explore work-related predictors of work participation 6 and 12 months after mild-to-moderate TBI.

SETTING

Data were collected at baseline 8 to 12 weeks after injury, and 3, 6, and 12 months after baseline, at a specialized TBI rehabilitation outpatient clinic at Oslo University Hospital, Oslo, Norway.

PARTICIPANTS

Eligible patients had suffered a mild-to-moderate TBI 8 to 12 weeks previously, were employed 50% or more at time of injury, were between 18 and 60 years of age, and sick listed 50% or more at time of inclusion due to symptoms of TBI (based on the Rivermead Post-Concussion Symptoms Questionnaire). In total, 116 patients were included in a randomized controlled trial, of whom 113 were included in the 1-year analysis.

DESIGN

Patients were originally included in a randomized controlled trial. There were no between-group differences in RTW after 1 year. Thus, the participants were evaluated as one cohort in this study.

MAIN MEASURES

The primary outcome measure was work participation 1 year after study inclusion. Work-related predictors were chosen on the basis of previous research and expert opinion and entered into a multivariable linear regression model. The model controlled for sociodemographic and injury-related factors.

RESULTS

The best-fitting model explained 25% of variation in work participation at 1 year. Significant predictors were predictability, quantitative demands and rewards (recognition) at the workplace, private or public employment, symptom burden at baseline, and sex.

CONCLUSION

In this study, several work-related predictors outperformed some of the established sociodemographic and injury-related predictors of RTW after TBI, thus stressing the need for further focus and research on amendable predictors of RTW after mild-to-moderate TBI.

Post-concussion symptoms 1-year after traumatic brain injury: using the Rivermead Post-concussion Questionnaire to identify predictors of severity

BACKGROUND

Patients who suffer traumatic brain injury (TBI) often experience a constellation of physical, cognitive, and emotional/behavioral symptoms called "post-concussion symptoms" and subsequent long-term disability. This study aimed to investigate the incidence of persistent post-concussion symptoms and possible predictors of long-term disability focusing on demographic, injury, and psychological factors. It was hoped to identify groups at high risk.

METHODS

A prospective cohort of 1322 individuals admitted with TBI were assessed in a specialist neurorehabilitation clinic at 10 weeks and 1-year post injury between August 2011 and July 2015. The outcome (post-concussion symptoms) was measured using the Rivermead Post-concussion Questionnaire (RPQ) at 1-year post injury.

RESULTS

At 1 yr, 1131 individuals were identified (>90% follow-up). Over 20% exhibited moderate or severe symptom levels on RPQ. A linear regression model showed that previous psychiatric history, lower Glasgow Coma Scale (GCS), severe CT abnormalities, injury caused by assault, pre-injury unemployment, and inability to return to work at 6 weeks post-injury were associated with worse symptoms at 1 yr. The adjusted R² of the model was 25.1%.

CONCLUSION

These findings confirm the high incidence of post-concussion symptoms at 1 yr and identify certain associated features that increase risk. This may allow targeting of certain groups, e.g., return to work or victims of assault.

Identifying models, processes, and components of vocational rehabilitation following acquired brain injury: a systematic scoping review

PURPOSE

Acquired brain injury (ABI) is a complex injury which impacts engagement with worker roles. Return to work (RTW) rates for individuals with brain injury are low and those who do RTW often report job instability. Vocational rehabilitation (VR) can improve RTW rates and job stability; however, service provision is varied, and no gold standard has been identified.

METHODS

A systematic scoping review of the literature was completed to explore research activity in VR for individuals with ABI to address the following three questions: what models have been identified to underpin VR in ABI? What clinical processes have been identified to guide provision of VR in ABI? What components of VR have been described and/or recommended in the ABI literature?

RESULTS

The number of included articles was 57. From these articles, 16 models, nine process steps, eight components, and four service delivery components were identified that were utilised in provision of ABI VR. Implications for practice are discussed.

CONCLUSIONS

Key processes and components of ABI VR have been identified across a range of models and apply to clients at all phases post-injury. Findings may be used to inform service provision across a range of time points and support clinicians in their delivery of VR to adults with brain injury.Implications for RehabilitationPeople with acquired brain injury (ABI), even severe injury, can be successful with return to work (RTW) when provided appropriate supports.A wide range of models, interventions, and service components have been identified in the literature which can be used to guide clinical and policy development in ABI vocational rehabilitation.Vocational rehabilitation for individuals with brain injury involves a complex interaction of factors, and consideration should be paid to not only the person and their abilities but also job demands and the environment (physical, social, cultural).Vocational rehabilitation services should be accessible and timed to maximise chances of a successful RTW, provided by a coordinated interdisciplinary team and should involve active stakeholder engagement.

Workplace accommodation in return to work after mild traumatic brain injury

BACKGROUND: While a vast amount of research focuses on unmodifiable and individual factors that may impact return to work (RTW) for patients with traumatic brain injury (TBI), less knowledge exists of the relationship between specific workplace factors and work retention. OBJECTIVE: Identify types of accommodation in the workplace that influence the RTW process for employees with TBI and the challenges associated with them. METHODS: A multiple case study consisting of 38 cases and 109 interviews of employees with TBI and their managers conducted between 2017 and 2020 at two time points. RESULTS: Accommodation of both the organizational and psychosocial work environment influences RTW for employees with TBI. Social support and supportive management may have positive and negative effects. RTW is often not a linear process. Over time, maintaining and developing customized accommodation in the work organization is challenging. CONCLUSIONS: Uncertainty about accommodation in RTW for employees with TBI is closely linked to lack of knowledge in the workplace of how to handle complex and nonlinear RTW processes. Work-oriented rehabilitation should to a greater extent provide managers with relevant information and support to develop the person-environment fit over time.

Predictive Factors of Return Home and Return to Work for Intensive Care Unit Survivors after Traumatic Brain Injury with a Follow-up Period of 2 Years

Intensive care unit (ICU) survivors after traumatic brain injury (TBI) frequently have serious disabilities with subsequent difficulty in reintegration into society. We aimed to investigate outcomes for ICU survivors after moderate to severe TBI (msTBI) and to identify predictive factors of return home (RH) and return to work (RTW). This single-center retrospective cohort study was conducted on all trauma patients admitted to the emergency ICU of our hospital between 2013 and 2017. Of these patients, adult (age ≥ 18 years) msTBI patients with head Abbreviated Injury Scale ≥ 3 were extracted. We performed univariate/multivariate logistic regression analyses to explore the predictive factors of RH and RTW. Among a total of 146 ICU survivors after msTBI, 107 were included (median follow-up period: 26 months). The RH and RTW rates were 78% and 35%, respectively. Multivariate analyses revealed that the predictive factors of RH were age < 65 years (P < 0.001), HR < 76 bpm (P = 0.015), platelet count ≥ 19 × 10⁴/μL (P = 0.0037), D-dimer < 26 μg/mL (P = 0.034), and Glasgow Coma Scale (GCS) score > 8 (P = 0.0015). Similarly, the predictive factors of RTW were age < 65 years (P < 0.001) and GCS score > 8 (P = 0.0039). This study revealed that “age” and “GCS score on admission” affected RH and RTW for ICU survivors after msTBI.

Transition back to work after mild TBI: a qualitative study

BACKGROUND

While many persons who sustain a mild traumatic brain injury (MTBI) can resume work shortly after their injury, some experience persisting symptoms leading to longer-term sickness absence. In-depth knowledge about how these persons experience the return to work (RTW) process is needed.

AIMS

To explore how persons with MTBI experience the process of returning to ordinary competitive work after a prolonged period of sickness absence.

MATERIAL AND METHODS

Semi-structured interviews were conducted with six persons (four women) approximately 12 months after sustaining an MTBI. Data were analysed using a stepwise-deductive inductive method.

RESULTS

When starting work the participants experienced a crisis. They described the importance of making the actual decision to RTW. Being present at the workplace was significant. In the process of increased workload, they expressed having challenges related to time perception and capacity restrictions. The importance of being seen and valued was emphasised. When reintegrated into the workplace revaluing work tasks and priorities shaped the RTW process as well as a further professional career.

CONCLUSIONS AND SIGNIFICANCE

The process of RTW contained the experience of unpredictability and incompatibility with own identity and performance. Working had an impact on social participation, self-worth, daily structure, as well as reconstructing occupational biography.

Factors related to the quality and stability of partner relationships after traumatic brain injury: A systematic literature review

OBJECTIVE

The latest literature review on partner relationships following traumatic brain injury (TBI), conducted a decade ago, discussed solely quantitative work and noted significant knowledge gaps. The current review updates and expands on this work by providing an overview of the current state of knowledge on factors related to relationship quality and stability following TBI.

DATA SOURCES

CINAHL, Embase, MEDLINE, Psychology and Behavioral Sciences Collection, APA PsycINFO, and PubMed were searched on April 23, 2020, for literature on factors associated with 1)relationship quality and 2)relationship stability following TBI.

STUDY SELECTION

English quantitative and qualitative studies investigating factors associated with relationship quality and/or stability following TBI were included. Two reviewers independently assessed eligibility. If consensus was not reached, a third reviewer's conclusion was decisive. Forty-three studies were included.

DATA EXTRACTION

Information regarding study objectives and characteristics, participant demographics, (in)dependent variables, and main findings was extracted. Study quality was rated using the JBI Checklist for Analytical Cross Sectional Studies and/or the CASP Checklist for Qualitative Research. Both were performed by the lead reviewer and checked by the second reviewer.

DATA SYNTHESIS

Thirty-eight factors related to relationship quality and/or stability were identified, covering injury characteristics (e.g., severity), body functions (e.g., personality changes), activities (e.g., communication), participation (e.g., social dependence), environment (e.g., children), and personal factors (e.g., coping strategies).

CONCLUSIONS

Relationship quality and stability following TBI are found to be related to a multitude of factors, including newly identified factors such as personality changes and dependence. Future research may wish to quantitatively investigate factors thus far only identified in qualitative research, explore possible positive effects of TBI on relationships, study the experiences of same-sex couples, and include the perspectives of both partners with and without the injury.

Shades of Rage: Applying the Process Model of Emotion Regulation to Managing Anger After Brain Injury

Uncontrollable anger is common following an acquired brain injury (ABI), with impaired emotion regulation (ER) being one of the main contributors. Existing psychological interventions appear moderately effective, though studies typically include limitations such as small sample sizes, issues of long-term efficacy, and standardization of content. While ER has been a popular research field, the study of ER for anger management after ABI is less well investigated, and contains few interventions based on the widely used Process Model of ER. This review surveys the efficacy of ER strategies in individuals with ABI, and proposes a novel research design for future interventions. Recommendations are made about: strategy number and type, shared decision-making, approaches to data analysis, and mode of delivery.

Community reintegration of people with traumatic brain injury in south India: role of a comprehensive transdisciplinary rehabilitation programme

Background/aims

Successful community reintegration is the ultimate goal of traumatic brain injury rehabilitation and care. The aim of this study was to explore the community reintegration of people with a traumatic brain injury living in south India who had completed a comprehensive holistic rehabilitation programme. The level of community reintegration based on the demographic variables of the patients was also investigated.

Methods

A total of 104 community-dwelling people with a traumatic brain injury, and a minimum of 1 year post injury, received treatment from a rehabilitation team in a therapeutic centre for 7 hours a day, 6 days a week for a maximum of 16 weeks. A usual care, transdisciplinary service delivery model was implemented, and the Craig Handicap Assessment and Reporting Technique was used to quantify the main outcome measures.

Results

The mean and standard deviation scores for each Craig Handicap Assessment and Reporting Technique domain were physical independence (91 ± 23), social integration (87 ± 20), cognitive independence (70 ± 33), economic self-sufficiency (67 ± 40), occupation (66 ± 40) and mobility (63 ± 29). The participants who had gone back to work after their traumatic brain injury showed significantly higher scores in all the domains of the Craig Handicap Assessment and Reporting Technique than those who were unemployed. Only the occupation and mobility domain scores were influenced by the severity of the traumatic brain injury. The economic self-sufficiency, occupation and mobility domain scores were higher among married patients compared to those who were unmarried.

Conclusions

A significant proportion of the participants were able to return to work and reintegrate into community life through this service delivery model. This comprehensive, holistic approach, which targets physical, cognitive and psychosocial needs and then provides adequate vocational rehabilitation, can result in good outcomes in people with a traumatic brain injury.

The Influence of Hard Hat Design Features on Head Acceleration Attenuation

This study evaluated the performance of 6 commercially available hard hat designs-differentiated by shell design, number of suspension points, and suspension tightening system-in regard to their ability to attenuate accelerations during vertical impacts to the head. Tests were conducted with impactor materials of steel, wood, and lead shot (resembling commonly seen materials in a construction site), weighing 1.8 and 3.6 kg and dropped from 1.83 m onto a Hybrid III head/neck assembly. All hard hats appreciably reduced head acceleration to the unprotected condition. However, neither the addition of extra suspension points nor variations in suspension tightening mechanism appreciably influenced performance. Therefore, these results indicate that additional features available in current hard hat designs do not improve protective capacity as related to head acceleration metrics.

A 10-Year Review of Spatio-Temporal Patterns of Firearm Injury in a Rural Setting

INTRODUCTION

West Virginia (WV) had the ninth highest rate of firearm mortality of all states in the United States according to the CDC in 2018. Gun violence in WV has been a steady problem over the last decade. The rural population is more vulnerable to unintentional firearm injuries and suicides. Previously published literature from urban settings has demonstrated a link between firearm injuries and modifiable situational variables such as crime, unemployment, low income, and low education. There are very few studies that have utilized geospatial analytic techniques as a tool for injury mapping, surveillance, and primary prevention in rural and frontier zones of the United States.

METHODS

We performed a 10-year retrospective single-institution review of firearm injuries at a rural WV level 1 trauma center between January 2010 and December 2019. The AIS World Geocoding Service was then used to identify specific areas of emerging firearm-related injuries within the service area.

RESULTS

Specific hot spots of emerging firearm injury were identified in both intentional and unintentional populations. These were located in geographically distinct areas of the WV unincorporated rural and frontier population. These rural WV hotspots were associated with the modifiable variables of crime, unemployment, lower income, and lower education level.

CONCLUSIONS

Emerging hot spots of firearm injury in rural and frontier locations were associated with modifiable social determinants. These areas represent an opportunity for targeted injury prevention efforts addressing these disparities. Further prospective study of these findings is warranted.

Developing mHealth to the Context and Valuation of Injured Patients and Professionals in Hospital Trauma Care: Qualitative and Quantitative Formative Evaluations (Preprint)

Background

Trauma care faces challenges to innovating their services, such as with mobile health (mHealth) app, to improve the quality of care and patients’ health experience. Systematic needs inquiries and collaborations with professional and patient end users are highly recommended to develop and prepare future implementations of such innovations.

Objective

This study aimed to develop a trauma mHealth app for patient information and support in accordance with the Center for eHealth Research and Disease Management road map and describe experiences of unmet information and support needs among injured patients with trauma, barriers to and facilitators of the provision of information and support among trauma care professionals, and drivers of value of an mHealth app in patients with trauma and trauma care professionals.

Methods

Formative evaluations were conducted using quantitative and qualitative methods. Ten semistructured interviews with patients with trauma and a focus group with 4 trauma care professionals were conducted for contextual inquiry and value specification. User requirements and value drivers were applied in prototyping. Furthermore, a complementary quantitative discrete choice experiment (DCE) was conducted with 109 Dutch trauma surgeons, which enabled triangulation on value specification results. In the DCE, preferences were stated for hypothetical mHealth products with various attributes. Panel data from the DCE were analyzed using conditional and mixed logit models.

Results

Patients disclosed a need for more psychosocial support and easy access to more extensive information on their injury, its consequences, and future prospects. Health care professionals designated workload as an essential issue; a digital solution should not require additional time. The conditional logit model of DCE results suggested that access to patient app data through electronic medical record integration (odds ratio [OR] 3.3, 95% CI 2.55-4.34; P<.001) or a web viewer (OR 2.3, 95% CI 1.64-3.31; P<.001) was considered the most important for an mHealth solution by surgeons, followed by the inclusion of periodic self-measurements (OR 2, 95% CI 1.64-2.46; P<.001), the local adjustment of patient information (OR 1.8, 95% CI 1.42-2.33; P<.001), local hospital identification (OR 1.7, 95% CI 1.31-2.10; P<.001), complication detection (OR 1.5, 95% CI 1.21-1.84; P<.001), and the personalization of rehabilitation through artificial intelligence (OR 1.4, 95% CI 1.13-1.62; P=.001).

Conclusions

In the context of trauma care, end users have many requirements for an mHealth solution that addresses psychosocial functioning; dependable information; and, possibly, a prediction of how a patient’s recovery trajectory is evolving. A structured development approach provided insights into value drivers and facilitated mHealth prototype enhancement. The findings imply that iterative development should move on from simple and easily implementable mHealth solutions to those that are suitable for broader innovations of care pathways that most—but plausibly not yet all—end users in trauma care will value. This study could inspire the trauma care community.

Factors associated with employment stability following traumatic brain injury, in a sample who have received comprehensive vocational rehabilitation

PURPOSE

To quantify employment stability of individuals with traumatic brain injury (TBI) who received comprehensive vocational rehabilitation (VR) using different measures to identify difficulties experienced and factors associated with employment stability.

MATERIALS AND METHODS

72 individuals with predominantly moderate-severe TBI were interviewed. Neuropsychological assessment scores were collected. Three employment stability measures were used: number of post-injury employers, duration with employer and average weekly hours. Descriptive and predictive analyses were performed.

RESULTS

90.2% remained employed at time of interview (Mean = 4.83 years post-injury). However, participants worked significantly fewer hours, 63.9% had changed roles or employers at least once and only 51% achieved their pre-injury level of responsibility. 61% reported a high level of employer support. Self-reported difficulties included physical sequelae, memory problems and fatigue. Post-injury testing found impaired memory (34.4%) and processing speed (49.2%). After accounting for time since injury, demographic and employment variables (older age, male gender, higher pre-injury skill-level, higher level of employer support), higher level of injury-related difficulties and lower level of cognitive function significantly predicted employment stability.

CONCLUSION

Injury-related difficulties impact employment long-term, necessitating ongoing work modifications. Individualised VR is important, not only to facilitate return to work but to support long-term employment stability after TBI.Implications for rehabilitationBeing male was associated with working more hours, and having faster processing speed, lower levels of fatigue and ongoing physical sequelae were associated with a longer duration with the same employer.Initial return to work is often the first step on a long journey as injury-related difficulties can continue to impact work in the-long term and require lasting modifications to duties and working hours.VR should include ongoing follow-up to facilitate work modifications and support both the employer and the employee in adjusting to these.VR should be individualised to support the impact of the unique cognitive and physical limitations experienced by each individual with TBI, based on the needs and employment demands of each workplace.

Predictors of return to work after moderate-to-severe traumatic brain injury: a systematic review of current literature and recommendations for future research

PURPOSE

To identify factors associated with employment between six months and five years after traumatic brain injury (TBI).

METHODS

Using a predefined search algorithm, four electronic databases were searched for literature published between 2014 and the first half of April 2021 containing predictors of employment outcome. Data were selected in accordance with the PRISMA flow and the whole process was conducted by two reviewers who had to attain a consensus. The study results were discussed with an expert panel, in order to provide guidance for future research on this topic.

RESULTS

This review found clear evidence for employment status at time of injury, occupation at time of injury, Glasgow Coma Scale, length of stay, disability level and primary payer to be predictors of return to work after TBI.

CONCLUSIONS

More literature investigating in depth the functioning and environmental factors is required for further improvement of predictions, rehabilitation and policy.Implications for rehabilitationThis study identifies predictors of return to work in TBI patients, which can be used to identify patients with high risk early in the recovery process.Current literature shows difficulties with general functioning are a barrier for return to work, but gives no indication about effective therapeutic interventions.More knowledge about modifiable factors is desirable to improve rehabilitation and, thereby, employment outcomes after TBI.

Post-concussion symptoms three months after mild-to-moderate TBI: characteristics of sick-listed patients referred to specialized treatment and consequences of intracranial injury

Objective: To present pre-injury, injury-related, work-related and post-injury characteristics, and to compare patients with and without traumatic intracranial abnormalities, in a treatment-seeking sample with persistent post-concussion symptoms (PPCS) after mild-to-moderate TBI.Methods: Cross-sectional design in the context of a specialized TBI outpatient clinic. Eligible patients were aged 18-60 years, employed ≥ 50% at time of injury, and sick listed ≥ 50% at inclusion due to PPCS. Data were collected 8-12 weeks after injury through review of medical records, semi-structured interviews, questionnaires, and neuropsychological screening.Results: The study included 116 patients, of whom 60% were women, and predominantly white-collar workers in full-time positions. Ninety-four percent had a mild TBI, and 23% had intracranial abnormalities. The full sample reported high somatic, emotional, and cognitive symptom burden, and decreased health-related quality of life. Patients with normal CT/MRI results reported higher overall symptom burden, while patients with intracranial abnormalities had worse memory function.Conclusion: Injury severity and traumatic intracranial radiological findings should not be the sole ground for planning of rehabilitation service provision in patients with PPCS, as subjective complaints do not necessarily co-vary with these variables.

Cognitive and vocational rehabilitation after mild-to-moderate traumatic brain injury: A randomised controlled trial

BACKGROUND

Returning to work is often a primary rehabilitation goal after traumatic brain injury (TBI). However, the evidence base for treatment options regarding return to work (RTW) and stable work maintenance remains scarce.

OBJECTIVE

This study aimed to examine the effect of a combined cognitive and vocational intervention on work-related outcomes after mild-to-moderate TBI.

METHODS

In this study, we compared 6 months of a combined compensatory cognitive training and supported employment (CCT-SE) intervention with 6 months of treatment as usual (TAU) in a randomised controlled trial to examine the effect on time to RTW, work percentage, hours worked per week and work stability. Eligible patients were those with mild-to-moderate TBI who were employed ≥50% at the time of injury, 18 to 60 years old and sick-listed ≥50% at 8 to 12 weeks after injury due to post-concussion symptoms, assessed by the Rivermead Post Concussion Symptoms Questionnaire. Both treatments were provided at the outpatient TBI department at Oslo University Hospital, and follow-ups were conducted at 3, 6 and 12 months after inclusion.

RESULTS

We included 116 individuals, 60 randomised to CCT-SE and 56 to TAU. The groups did not differ in characteristics at the 12-month follow-up. Overall, a high proportion had returned to work at 12 months (CCT-SE, 90%; TAU, 84%, P=0.40), and all except 3 were stably employed after the RTW. However, a significantly higher proportion of participants in the CCT-SE than TAU group had returned to stable employment at 3 months (81% vs. 60%, P=0.02).

CONCLUSION

These results suggest that the CCT-SE intervention might help patients with mild-to-moderate TBI who are still sick-listed 8 to 12 weeks after injury in an earlier return to stable employment. However, the results should be replicated and a cost-benefit analysis performed before concluding.

Impaired self-awareness after traumatic brain injury: A systematic review. Part 2. Consequences and predictors of poor self-awareness

BACKGROUND

Impaired self-awareness (ISA) has frequently been found both frequent and deleterious in patients with moderate to severe traumatic brain injury (TBI).

OBJECTIVES

This is the second of a two-part systematic review on ISA after TBI, focusing on the consequences and predictors of ISA after TBI.

METHODS

Following the PRISMA guidelines, 95 articles meeting the inclusion criteria were included; 46 were specifically related to this second part of the review.

RESULTS

Among 16 studies that investigated the effect of ISA on outcome, most (n=13) found poor self-awareness associated with poor rehabilitation, functional, social and vocational outcome and with increased burden on relatives. Multiple factors have been found associated with increased frequency of ISA. ISA was found significantly related to injury severity in 8 of 10 studies, impaired executive functions in 12 of 15 studies, and poor social cognition in 3 studies, but paradoxically inverse associations were repeatedly found between self-awareness and emotional status (11 of 12 studies). Finally, although research in the field is still scarce, ISA seems associated with a dysfunction within brain networks involving the anterior cingulate cortex, anterior insula and fronto-parietal control network.

CONCLUSIONS

ISA is a complex and multifaceted disorder associated with poor rehabilitation outcome, severe injuries, and deficits of executive functions and social cognition but has an inverse association with mood impairments.

Impaired self-awareness after traumatic brain injury: a systematic review. Part 1: Assessment, clinical aspects and recovery

BACKGROUND

Impaired self-awareness (ISA) has frequently been found to be both frequent and deleterious in patients with moderate to severe traumatic brain injury (TBI).

OBJECTIVES

The present paper is the first of a two-part systematic review of ISA after traumatic brain injury (TBI), focusing on assessment methods, clinical aspects and recovery.

METHODS

Following the PRISMA guidelines, 95 articles meeting the inclusion criteria were included.

RESULTS

ISA occurs in 30% to 50% of patients with moderate to severe TBI, although it tends to improve with time. There is no one single gold-standard measure of ISA. Self-proxy discrepancy scores, with scales such as the Patient Competency Rating Scale or the Awareness Questionnaire, or a structured interview such as the Self Awareness of Deficits Interview, are the most frequently used assessment methods, with adequate psychometric properties. Scores on these different scales correlate only moderately with each other, which suggests that they may address different aspects of self-awareness. ISA mainly concerns cognitive and behavioral problems rather than physical or sensory impairments and may concern different areas of functioning, such as anticipatory, emergent or meta-cognitive awareness.

CONCLUSION

ISA is a complex and multifaceted issue that should be systematically assessed in rehabilitation settings using a range of relatively well-validated tools. The consequences and predictors of ISA after TBI will be addressed in a companion paper.

Association between the Wechsler Adult Intelligence Scale III and early return to work after traumatic brain injury

BACKGROUND

Residual capacity evaluation via neuropsychological testing can facilitate the development of a rehabilitation plan in patients following a traumatic brain injury (TBI).

OBJECTIVE

This study aimed to confirm the tasks that patients must perform well for early return to work (RTW) following TBI using the Wechsler Adult Intelligence Scale III (WAIS-III).

METHODS

In total, 40 male and 13 female patients who suffered from neurobehavioral disabilities following TBI were recruited and classified into two groups: the successfully returned to work group (SRTW-G; n = 22) and the unsuccessfully returned to work group (USRTW-G; n = 31). The outcomes assessed by WAIS-III and the time to RTW were compared between the SRTW-G and USRTW-G groups. Multiple logistic regression, multiple regression analysis, and Cox regression were employed to assess differences between the groups.

RESULTS

The Comprehension and Letter-Number Sequencing subtests of the WAIS-III were significantly correlated with early RTW more than the other subtests.

CONCLUSIONS

We found that, as reflected in the two subtests, patients with TBI must be able to perform well in the following tasks for early RTW: Retention of information for short time periods, information processing, and social judgment based on the knowledge of the patient's experience.

Employment status after traumatic brain injury and the effect of concomitant injuries on return to work

PURPOSE

This study aims to describe the employment status and pattern among survivors of traumatic brain injury after motor vehicle accidents, and to explore the effects of demographic, injury variables and concomitant injuries on the employment status .

METHOD

A retrospective analyses of 370 medical reports written for patients who sustained traumatic brain injury from motor vehicle accidents was conducted. To establish the employment pattern, the pre-injury employment history was compared to the latest employment status documented. Types and severity of concomitant injuries were rated according to Abbreviated Injury Scale criteria. All significant variables were further analyzed using logistic regression to explore predictors of employment.

RESULTS

Up to 87% of the patients sustained concomitant injuries, with more than two-thirds (72%) scoring ≤ 2 on the Abbreviated Injury Scale. One hundred and eighty-two patients (49.2%) successfully returned to work. Among those who returned to work, 34% returned to former employment with pre-injury job description. Severity of traumatic brain injury, length of acute hospital stay, ambulation status and cognitive status were found to be significant predictive factors for employment status post traumatic brain injury. Presence of concomitant extremity injuries was found to influence the employment pattern among traumatic brain injury survivors.

CONCLUSION

The return to work rate was somewhat low and was not influenced by presence of concomitant injuries. .

Vocational Outcomes After Traumatic Brain Injury; Prevalence and Risk Factors After 1 Year in a Multivariable Model

OBJECTIVE

To determine the prevalence of employment status (ES) or full-time study after traumatic brain injury (TBI) in a representative population and its predictive factors.

DESIGN

Prospective cohort study.

SETTING

Regional Major Trauma Centre. Participants: In total, 1734 consecutive individuals of working age, admitted with TBI to a Regional Trauma Centre, were recruited and followed up at 8 weeks and 1 year with face-to-face interview. Median age was 37.2 years (17.5-58.2); 51% had mild TBI, and 36.8% had a normal computed tomographic (CT) scan. Main Outcome Measure: Complete or partial/modified return to employment or study as an ordinal variable.

RESULTS

At 1 year, only 44.9% returned to full-time work/study status, 28.7% had a partial or modified return, and 26.4% had no return at all. In comparison with status at 6 weeks, 9.9% had lower or reduced work status. Lower ES was associated with greater injury severity, more CT scan abnormality, older age, mechanism of assault, and presence of depression, alcohol intoxication, or a psychiatric history. The multivariable model was highly significant (P < .001) and had a Nagelkerke R2 of 0.353 (35.3%).

CONCLUSIONS

Employment at 1 year is poor and changes in work status are frequent, occurring in both directions. While associations with certain features may allow targeting of vulnerable individuals in future, the majority of model variance remains unexplained and requires further investigation.

Exploring the lived return-to-work experience of individuals with acquired brain injury: use of vocational services and environmental, personal and injury-related influences

PURPOSE

To explore work outcomes, vocational services, barriers and facilitators for returning to work in individuals with acquired brain injury (ABI) in Queensland, Australia and to identify areas for improvement.

DESIGN AND METHODS

Ten semi-structured interviews were conducted with individuals with ABI (stroke, traumatic brain injury, tumour). Interviews were analysed using a realist thematic analysis approach.

RESULTS

Participants either returned to the same work, different work, did not maintain work or did not have any work since their injury. Use of vocational services depended on participants' needs and insurance. Facilitators for return to work (RTW) were a supportive workplace and family, vocational rehabilitation that met the individual's needs, insurance coverage and self-motivation. Workplaces that were not understanding of brain injury, employment service providers who were unable to find work for participants, and physical and cognitive deficits were barriers to RTW. Workplaces, employment service providers and individuals require more information about the deficits associated with brain injury.

CONCLUSIONS

The use and effectiveness of vocational services were variable across participants and depended on insurance coverage and needs. Barriers and facilitators for RTW were affected by both the environment and the individual. Implications for vocational rehabilitation were identified.Implications for RehabilitationA supportive workplace and family, and access to appropriate vocational rehabilitation are important environmental facilitators for RTW in individuals with ABI.Workplaces with a poor understanding of ABI and employment service providers unable to find work for individuals with ABI are environmental barriers to RTW.Workplaces, employment service providers and individuals with ABI require more information about the physical and cognitive deficits associated with ABI.Employment service providers need more training to develop comprehensive strategies to help individuals with ABI find new employment.

Consumer perspectives of vocational rehabilitation and return to work following acquired brain injury

Introduction:

Following acquired brain injury, the goal of return to work is common. While return to work is supported through different rehabilitation models and services, access to vocational rehabilitation varies within and between countries, and global rates of employment post-injury remain low. The literature identifies outcomes from vocational programs and experiences with return to work, yet little is known about individuals’ perceptions and experiences regarding rehabilitation to support their vocational goals and experiences in attempting to return to work.

Method:

This qualitative study investigated the experiences of community-living adults with acquired brain injury (n = 8; mean age 45 years; mean time post-injury of 5.5 years) regarding their vocational rehabilitation and return to work. Focus groups and semi-structured interviews were conducted, with data analyzed via thematic analysis.

Results:

Participants identified negative and positive experiences with vocational rehabilitation and return to work. Five overarching themes were identified: addressing vocational rehabilitation in rehabilitation; facilitators of recovery and return to work; the importance and experience of working again; acquired brain injury and identity; and services, systems and policies. Participants also identified five key areas for early vocational rehabilitation services: education; service provision; employer liaison; workplace supports; and peer mentors. Study findings inform current and future practice and service delivery, at a clinical, service and system level.

Feasibility of a home-based environmental enrichment paradigm to enhance purposeful activities in adults with traumatic brain injury: a case series

PURPOSE

To assess the feasibility, safety, and functional recovery of an Environmental Enrichment (EE) inspired paradigm for enhancing daily activities in people with traumatic brain injury.

METHODS

Two TBI-Caregiver dyads participated in the six-month study. A preinstalled harness provided the support structure that enabled the family to perform task-specific functional and cognitive goals. The pre- and post-intervention evaluations included the safety, feasibility, and clinical outcomes such as the 10-m walk test, the Timed Up and Go test, the Jebsen Hand Function test, the Six-Minute Walk test, and the Trail Making Test. The Actigraph GT9X recorded the Caregiver-TBI step count during days spent in harness and out of harness.

RESULTS

The study was feasible, safe, and both TBI subjects improved in functional outcomes. Analysis of Actigraph GT9X yielded mixed results.

CONCLUSION

A partnership with caregivers and adults with TBI to design an EE-focused community program could improve functional activities in real life. To optimize this intervention, caregivers will likely need an alternate approach to record time spent in the harness.IMPLICATIONS FOR REHABILITATIONThe complexities of the real world encourage meaningful activities and participation.Autonomy in everyday activities is an important long-term objective for adults with brain injury.Community-tailored harnesses designed to prevent falls encourages physical activity and social interaction.

Evaluating the Cross-Sectional and Longitudinal Relationships Predicting Suicidal Ideation Following Traumatic Brain Injury

OBJECTIVE

Characterize relationships among substance misuse, depression, employment, and suicidal ideation (SI) following moderate to severe traumatic brain injury (TBI).

DESIGN

Prospective cohort study.

SETTING

Inpatient rehabilitation centers with telephone follow-up; level I/II trauma centers in the United States.

PARTICIPANTS

Individuals with moderate to severe TBI with data in both the National Trauma Data Bank and the Traumatic Brain Injury Model Systems National Database, aged 18 to 59 years, with SI data at year 1 or year 2 postinjury (N = 1377).

MAIN OUTCOME MEASURE

Primary outcome of SI, with secondary employment, substance misuse, and depression outcomes at years 1 and 2 postinjury.

RESULTS

Cross-lagged structural equation modeling analysis showed that year 1 unemployment and substance misuse were associated with a higher prevalence of year 1 depression. Depression was associated with concurrent SI at years 1 and 2. Older adults and women had a greater likelihood of year 1 depression. More severe overall injury (injury severity score) was associated with a greater likelihood of year 1 SI, and year 1 SI was associated with a greater likelihood of year 2 SI.

CONCLUSIONS

Substance misuse, unemployment, depression, and greater extracranial injury burden independently contributed to year 1 SI; in turn, year 1 SI and year 2 depression contributed to year 2 SI. Older age and female sex were associated with year 1 depression. Understanding and mitigating these risk factors are crucial for effectively managing post-TBI SI to prevent postinjury suicide.

Understanding the relationship between cognitive performance and function in daily life after traumatic brain injury

OBJECTIVE

Cognitive impairment is a key cause of disability after traumatic brain injury (TBI) but relationships with overall functioning in daily life are often modest. The aim is to examine cognition at different levels of function and identify domains associated with disability.

METHODS

1554 patients with mild-to-severe TBI were assessed at 6 months post injury on the Glasgow Outcome Scale-Extended (GOSE), the Short Form-12v2 and a battery of cognitive tests. Outcomes across GOSE categories were compared using analysis of covariance adjusting for age, sex and education.

RESULTS

Overall effect sizes were small to medium, and greatest for tests involving processing speed (ηp 2 0.057-0.067) and learning and memory (ηp 2 0.048-0.052). Deficits in cognitive performance were particularly evident in patients who were dependent (GOSE 3 or 4) or who were unable to participate in one or more major life activities (GOSE 5). At higher levels of function (GOSE 6-8), cognitive performance was surprisingly similar across categories. There were decreases in performance even in patients reporting complete recovery without significant symptoms. Medium to large effect sizes were present for summary measures of cognition (ηp 2 0.111), mental health (ηp 2 0.131) and physical health (ηp 2 0.252).

CONCLUSIONS

This large-scale study provides novel insights into cognitive performance at different levels of disability and highlights the importance of processing speed in function in daily life. At upper levels of outcome, any influence of cognition on overall function is markedly attenuated and differences in mental health are salient.

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.

A Scoping Review of Predictors of Community Integration Following Traumatic Brain Injury: A Search for Meaningful Associations

OBJECTIVE

The purpose of this scoping review was to identify predictors of community integration for adults with traumatic brain injury.

DATA SOURCES

We searched the PubMed and PsycINFO databases and reviewed references of included studies. We selected studies exploring multiple components of community integration, including instrumental activities of daily living, leisure activities, and social activities. A total of 53 studies were included.

DATA EXTRACTION

We extracted data on sample size and sample characteristics (stage of injury and recovery, severity) and examined predictor variables, outcome measures for community integration, and significant findings, reported as correlations.

DATA SYNTHESIS

We found that the predictors of community integration fell into 4 categories: demographics, injury characteristics, disability and impairments, and environmental factors. There was large variability in reported relationships for demographics (r = 0.01-0.43), injury characteristics (r = 0.01-0.58), disability/functional impairments (r = 0.003-0.98) and environmental factors (r = 0.11-0.58). Cognition, disability, mobility/physical functioning, mood, social support, and length of posttraumatic amnesia had the strongest relationships with community integration outcomes.

CONCLUSIONS

Strategies for the management of cognitive, physical, and emotional functioning, and building and training a strong support system, may facilitate community integration outcomes. Additional work is warranted to further explore the discrepancies found among studies.

An enhanced individual placement and support (IPS) intervention based on the Model of Human Occupation (MOHO); a prospective cohort study

BACKGROUND

Employment is good for physical and mental health, however people with severe mental illness (SMI) are often excluded from employment. Standard Individual Placement and Support (IPS) is effective in supporting around 55% of people with SMI into employment or education. Current research considers enhancements to IPS to improve outcomes for those requiring more complex interventions. Clinicians need to better understand who will benefit from these enhanced IPS interventions. This study offers a new enhanced IPS intervention and an approach to predicting who may achieve successful outcomes.

METHODS

This prospective cohort study included people with SMI who participated in an enhanced IPS service and had prolonged absence from employment. Secondary data analysis was conducted of data gathered in routine clinical practice. Univariate analysis coupled with previous research and clinical consultation was used to select variables to be included in the initial model, followed by a backward stepwise approach to model building for the final multiple logistic regression model with an outcome of successful or unsuccessful goal attainment (employment or education).

RESULTS

Sixty-three percent of participants in the enhanced IPS successfully attained employment or education. Significant relationships from bivariate analyses were identified between outcomes (employment or education) and seven psychosocial variables. Adapting Routines to Minimise Difficulties, Work Related Goals, and Living in an Area of Lesser Deprivation were found to be significant in predicting employment or education in the final multiple logistic regression model R² = 0.16 (Hosmer-Lemeshow), 0.19 (Cox-Snell), 0.26 (Nagelkerke).

CONCLUSION

An enhanced IPS service had a 63% rate success in achieving employment or education, higher than comparable studies and provides an alternative to IPS-Lite and IPS-standard for more complex populations. Motivational and habitual psychosocial variables are helpful in predicting who may benefit from an enhanced IPS intervention supporting people after prolonged absence from employment.

Reference Values of the QOLIBRI from General Population Samples in the United Kingdom and The Netherlands

The Quality of Life after Traumatic Brain Injury (QOLIBRI) instrument is an internationally validated patient-reported outcome measure for assessing disease-specific health-related quality of life (HRQoL) in individuals after traumatic brain injury (TBI). However, no reference values for general populations are available yet for use in clinical practice and research in the field of TBI. The aim of the present study was, therefore, to establish these reference values for the United Kingdom (UK) and the Netherlands (NL). For this purpose, an online survey with a reworded version of the QOLIBRI for general populations was used to collect data on 4403 individuals in the UK and 3399 in the NL. This QOLIBRI version was validated by inspecting descriptive statistics, psychometric criteria, and comparability of the translations to the original version. In particular, measurement invariance (MI) was tested to examine whether the items of the instrument were understood in the same way by different individuals in the general population samples and in the TBI sample across the two countries, which is necessary in order to establish reference values. In the general population samples, the reworded QOLIBRI displayed good psychometric properties, including MI across countries and in the non-TBI and TBI samples. Therefore, differences in the QOLIBRI scores can be attributed to real differences in HRQoL. Individuals with and without a chronic health condition did differ significantly, with the latter reporting lower HRQoL. In conclusion, we provided reference values for healthy individuals and individuals with at least one chronic condition from general population samples in the UK and the NL. These can be used in the interpretation of disease-specific HRQoL assessments after TBI applying the QOLIBRI on the individual level in clinical as well as research contexts.

Clinical Predictors of 3- and 6-Month Outcome for Mild Traumatic Brain Injury Patients with a Negative Head CT Scan in the Emergency Department: A TRACK-TBI Pilot Study

A considerable subset of mild traumatic brain injury (mTBI) patients fail to return to baseline functional status at or beyond 3 months postinjury. Identifying at-risk patients for poor outcome in the emergency department (ED) may improve surveillance strategies and referral to care. Subjects with mTBI (Glasgow Coma Scale 13–15) and negative ED initial head CT < 24 h of injury, completing 3- or 6-month functional outcome (Glasgow Outcome Scale-Extended; GOSE), were extracted from the prospective, multicenter Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Pilot study. Outcomes were dichotomized to full recovery (GOSE = 8) vs. functional deficits (GOSE < 8). Univariate predictors with p < 0.10 were considered for multivariable regression. Adjusted odds ratios (AOR) were reported for outcome predictors. Significance was assessed at p < 0.05. Subjects who completed GOSE at 3- and 6-month were 211 (GOSE < 8: 60%) and 185 (GOSE < 8: 65%). Risk factors for 6-month GOSE < 8 included less education (AOR = 0.85 per-year increase, 95% CI: (0.74–0.98)), prior psychiatric history (AOR = 3.75 (1.73–8.12)), Asian/minority race (American Indian/Alaskan/Hawaiian/Pacific Islander) (AOR = 23.99 (2.93–196.84)), and Hispanic ethnicity (AOR = 3.48 (1.29–9.37)). Risk factors for 3-month GOSE < 8 were similar with the addition of injury by assault predicting poorer outcome (AOR = 3.53 (1.17–10.63)). In mTBI patients seen in urban trauma center EDs with negative CT, education, injury by assault, Asian/minority race, and prior psychiatric history emerged as risk factors for prolonged disability.

Developing a model of long-term social rehabilitation after traumatic brain injury: the case of the head forward centre

Background: Social isolation and inactivity are highly problematic long-term consequences of Traumatic Brain Injury. They are rarely addressed by rehabilitation programmes, which focus on early phases of recovery. Day centres, or "drop-in" peer support groups, have emerged as an informal solution to social rehabilitation needs. However, there is a lack of knowledge regarding the therapeutic ingredients of these services.Methods: Twelve survivors of Traumatic Brain Injury that attended a social rehabilitation service (Head Forward Centre, UK; HFC), were interviewed to explore the meanings attached to the service and its activities. Thematic analysis was used to describe emerging themes and build a model of social rehabilitation.Results: Four therapeutic functions were attached to HFC: (a) HFC as a safe and predictable milieu; (b) HFC as a space where identity can be reconstructed; (c) HFC as a place where survivors can remain cognitive and socially active; (d) HFC as a network of continuous support.Conclusion: A model of long-term social rehabilitation should consider both psychological and practical/functional ingredients. Such a model can help informal rehabilitation services reflect upon their goals and activities, as well as articulate therapeutic actions along the rehabilitation path. The conceptualization of these four therapeutic ingredients in holistic rehabilitation models is described, and contrasted with its use in long-term social rehabilitation.IMPLICATIONS FOR REHABILITATIONSocial isolation and inactivity are important problems in the long-term rehabilitation of people with TBI. Both problems can be addressed by social rehabilitation services (day centres and peer support groups).Participation in social rehabilitation can promote a sense of normality and belongingness, which contribute to the long-term process of identity reconstruction.Social rehabilitation can help maintaining people with TBI cognitive and socially active, as well as developing a network of continuous support.

Prognostic factors for medical and productivity costs, and return to work after trauma

AIM

The aim of this study was to determine prognostic factors for medical and productivity costs, and return to work (RTW) during the first two years after trauma in a clinical trauma population.

METHODS

This prospective multicentre observational study followed all adult trauma patients (≥18 years) admitted to a hospital in Noord-Brabant, the Netherlands from August 2015 through November 2016. Health care consumption, productivity loss and return to work were measured in questionnaires at 1 week, 1, 3, 6, 12 and 24 months after injury. Data was linked with hospital registries. Prognostic factors for medical costs and productivity costs were analysed with log-linked gamma generalized linear models. Prognostic factors for RTW were assessed with Cox proportional hazards model. The predictive ability of the models was assessed with McFadden R2 (explained variance) and c-statistics (discrimination).

RESULTS

A total of 3785 trauma patients (39% of total study population) responded to at least one follow-up questionnaire. Mean medical costs per patient (€9,710) and mean productivity costs per patient (€9,000) varied widely. Prognostic factors for high medical costs were higher age, female gender, spine injury, lower extremity injury, severe head injury, high injury severity, comorbidities, and pre-injury health status. Productivity costs were highest in males, and in patients with spinal cord injury, high injury severity, longer length of stay at the hospital and patients admitted to the ICU. Prognostic factors for RTW were high educational level, male gender, low injury severity, shorter length of stay at the hospital and absence of comorbidity.

CONCLUSIONS

Productivity costs and RTW should be considered when assessing the economic impact of injury in addition to medical costs. Prognostic factors may assist in identifying high cost groups with potentially modifiable factors for targeted preventive interventions, hence reducing costs and increasing RTW rates.

What characterises work and workplaces that retain their employees following acquired brain injury? Systematic review

OBJECTIVES

The objective of this study was to conduct a systematic review assessing workplace factors related to work retention (or return to work) in employees with acquired brain injury (ABI). Additionally, we aimed to synthesise the evidence and state of knowledge on this subject.

METHODS

A database search was performed in nine relevant electronic databases. Inclusion criteria were quantitative peer-reviewed publications empirically investigating the relationship between work/workplace factors and work retention in employees following ABI. The methodological quality was determined by Effective Public Health Practice Project scoring, and evidence was synthesised narratively.

RESULTS

Thirteen studies were included. We found moderate evidence for a negative relationship between manual work and work retention. We also found limited evidence for a U-shaped relationship between workload and complete work retention at 6 months and no relationship at 12 months; a positive relationship between managers, compared with non-managers, and faster work retention; a positive relationship between large enterprise size defined as ≥250 employees, and no relationship between large enterprise size, defined as ≥1000 employees, and work retention.

CONCLUSION

Relative to individual factors, there is little evidence on specific workplace factors' relationship to work retention among employees with ABI. For most workplace factors, there were too few high-quality studies to designate evidence as more than limited or insufficient. Future studies should replicate rigorous studies of well-defined modifiable workplace factors related to work retention.
