Work-related difficulties in patients with traumatic brain injury: a systematic review on predictors and associated factors

The influence of socioeconomic status on management and outcomes in major trauma: A systematic review and meta-analysis

BACKGROUND

Major trauma is a leading cause of death and disability in younger individuals and poses a significant public health concern. There is a growing interest in understanding the complex relationships between socioeconomic deprivation and major trauma. Anecdotal evidence suggests that deprivation is associated with more violent and debilitating injuries. There remains a paucity in literature evaluating major trauma outcomes in relation to socioeconomic deprivation.

METHODS

A comprehensive search of MEDLINE, Embase, and CENTRAL databases was performed to identify studies from 1947 to March 2024. The primary outcome was to establish the distribution of injuries based on deprivation, with secondary outcomes evaluating surgical intervention rates, length of stay, and mortality. Quantitative pooling of data was based on the random-effects model.

RESULTS

Fourteen studies and 878,872 trauma patients were included. A substantial proportion (28%) of trauma incidents occurred in the most deprived group. Patients from the lowest socioeconomic group were considerably younger (weighted mean difference [WMD] -9.85 years and 95% confidence intervals [CI] -9.99 to -9.70) and more likely to be male (odds ratio [OR] 1.36 and 95% CI 1.14-1.63). There were no differences in surgical intervention (OR 1.74 and 95% CI 0.97-3.13), length of stay (WMD 1.15 days and 95% CI -0.32-2.62), and mortality (OR 1.04 and 95% CI 0.95-1.14) regardless of background.

CONCLUSION

Major trauma is prevalent in deprived areas and in younger individuals, with an increasing trend of deprivation in male patients. Although the rates of surgery, length of stay, and mortality did not differ between groups, planning of public health interventions should target areas of higher deprivation.

Peer mentor contributions to an early intervention vocational rehabilitation specialist service following trauma: A qualitative study

BACKGROUND

Peer mentors have a role in facilitating the participation, health and well-being of people who have had a traumatic injury. Few studies have explored the involvement of peer mentors in an early intervention vocational rehabilitation (EIVR) service following trauma.

OBJECTIVE

This study aimed to explore the experience of implementing peer support within the context of an EIVR service from the perspectives of the peer mentors themselves, the vocational therapists supervising them, and the patients that received peer mentoring.

METHODS

Semi-structured interviews were conducted with twenty participants from three groups: peer mentors (n = 4); vocational therapists (n = 3); and patients who received the EIVR intervention (n = 24). Data were thematically analysed.

RESULTS

Three themes were identified: The value of peer input in an EIVR service, The facilitators impacting the value of peer involvement as part of the EIVR service, The challenges impacting peer input as part of an EIVR service.

CONCLUSIONS

The inclusion of peer mentors early after major traumatic injury was a unique and valuable addition to the EIVR service. Offering peer support early on in rehabilitation enabled patients to gain a sense of hope for their future, and the expectation that returning to work was a realistic option. The careful selection of peer mentors, and ensuring they receive adequate preparation and ongoing supervision are vital to support their well-being during the intervention. Aiming to match peer mentors with similar injuries and work backgrounds to patients is an important contributor to the likely ongoing engagement of the mentee with the mentor.

Risk factors and service gaps affecting a sustainable work: a qualitative multi-stakeholder analysis in the context of persons with acquired brain injury living in Switzerland

INTRODUCTION

Along with the social and economic challenges posed by an aging society, creating work conditions that allow persons to stay healthy and work into old age has become a major task of Western societies. Retaining employment after returning to work is particularly difficult for individuals with a disability, as evidenced by the high rate of premature labor market dropout. Individuals with acquired brain injury (ABI) exemplify this challenge, as it often impairs cognitive, technical, and interpersonal abilities that are crucial in today's labor market. To effectively support these individuals, vocational integration practitioners require comprehensive knowledge of risk factors for premature labor market dropout and effective strategies for sustainable work.

OBJECTIVE

This study aimed to identify perceived risk factors and related service gaps regarding sustainable work for people with ABI, as reported by affected individuals, employers, vocational integration professionals, and health professionals.

METHODS

Secondary data analysis. Data that was originally collected through seven focus groups and two interviews with persons with ABI, 15 interviews with employers, and 13 interviews with vocational integration and health professionals in the context of the project 'Sustainable employment' was re-analysed thematically.

RESULTS

Two major themes of risk factors were identified: (1) person-related factors (including the subthemes: post-ABI impairments; lack of understanding of post-ABI impairments; poor health management) and (2) environment-related factors (including the subthemes: challenges related to the service structure; insufficient knowledge and education about ABI; challenges at the workplace; difficulties in private life). While stakeholders noted the variety of the currently available services, they particularly pointed to the missing long-term monitoring and counseling services for persons with ABI following the initial return-to-work, reflecting a major challenge for sustainable work. An overarching gap related to the fragmentation of the service structure and the lack of case coordination along the working life.

CONCLUSIONS

Multiple stakeholders emphasized the importance of empowering individuals, ensuring easy access to professional support, and providing a suitable work environment to address key risk factors and facilitate sustainable work for individuals with ABI. Continuous coaching, long-term monitoring and counseling following return-to-work, were identified as potential strategies to achieve these goals.

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.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Racial and ethnic differences in the association between mild traumatic brain injury and work duty limitations in the US military

OBJECTIVE

This study examined racial and ethnic differences in the association between mild traumatic brain injury (mTBI) and work duty limitations in active-duty service members (ADSMs).

METHODS

This study used retrospective and cross-sectional data from the 2019-2021 Military Health System Data Repository on 910,700 ADSMs who were 18-64 years old and were grouped into racial and ethnic categories of White, non-Hispanic; Black, non-Hispanic; Hispanic/Latino; and Asian or Pacific Islander, non-Hispanic.

RESULTS

Descriptive statistics showed that Black, Hispanic/Latino, and Asian or Pacific Islander patients had a lower proportion of having a diagnosis of mTBI compared to White patients (ps < 0.001). Further, the proportion of history of deployment varied by racial and ethnic group and deployment location. Multivariate logistic regression results showed odds of 1.52 (p < 0.001) for White patients with mTBI, odds of 1.61 (p < 0.001) for Black patients with mTBI, odds of 1.57 (p < 0.001) for Hispanic/Latino patients with mTBI, and odds of 1.99 (p < 0.001) for Asian or Pacific Islander patients with mTBI for being placed on work duty limitations.

DISCUSSION

These results advance our understanding of the work duty limitations for racial/ethnic minority patients with mTBI in the Military Health System.

Rehabilitation with intensive attention training early after acquired brain injury promotes better long-term status on health-related quality of life, daily activities, work ability and return to work

OBJECTIVE

To describe long-term effects on activity, participation, and quality of life (i) at different post-injury starting time points of attention training and (ii) of two different types of rehabilitation with attention training in patients after stroke or traumatic brain injury; and to describe their functioning level.

DESIGN

2 years after rehabilitation intervention, comparisons were made in one cohort receiving attention training subacute (< 4 months) or post-acute (4-12 months) and in one cohort with two different training methods, a process-based and an activity-based method respectively.

PATIENTS

100 patients were recruited from our earlier RCT study. They had mild to moderate stroke or traumatic brain injury with relatively limited symptomatology, and all had moderate to severe attention impairment.

METHODS

A questionnaire-based interview: EuroQol 5 dimensions, Occupational Gaps Questionnaire, Work Ability Index, self-assessed work status, self-reported employment conditions, sick leave, and experienced cognitive limitations in work performance.

RESULTS

An advantage for patients receiving subacute attention training regarding daily activities, work ability and returning to work.

CONCLUSION

The results indicate that subacute rehabilitation with attention training (< 4 months) is preferable compared to post-acute intervention (4-12 months). There were only minor differences between the training methods.

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.

Development and feasibility testing of a psychoeducational tool to support the return to work (RTW) of individuals with traumatic brain injury (TBI): The RTW after TBI app

To document the development and clinician evaluation of a psychoeducational and support tool: the return to work after traumatic brain injury app (RTW after TBI app). Co-design of the app involved the collaboration of traumatic brain injury (TBI) /vocational rehabilitation (VR) expert researchers (n = 4) and lived experience co-designers (individuals with TBI who had previously returned to work; n = 4). Twelve TBI/VR clinician reviewers then evaluated the app. Content analysis of TBI/VR clinician reviewers' interviews revealed four themes: content, usability (functional ease of use), utility (applicability to RTW after TBI) and suggestions for improvements. All clinicians reported that they would use the RTW after TBI app in their clinical practice. Although several aspects were reported to potentially limit the app's appropriateness for some TBI clients, many feasible improvements were suggested to address limitations. These improvements aim to increase the utility of the app with a wider range of clients and extend its use to other settings. Future research should evaluate, in a clinical trial, the efficacy of the RTW after TBI app in supporting individuals with TBI and their vocational providers and optimizing RTW success.

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.

Prioritizing risk factors and identifying target areas to address with interventions to improve sustainable employment of persons with a brain injury or a spinal cord injury - A multi-stakeholder consensus process

Background

Achieving sustainable long-term employment is the goal of work integration for persons with acquired brain injury (ABI) or spinal cord injury (SCI). However, decreasing employment rates over time for persons with ABI and SCI indicate that remaining employed in the long-term is a challenge.

Purpose

To identify the most important risk factors that pose a barrier to sustainable employment of persons with ABI or SCI from a multi-stakeholder perspective, and to propose corresponding interventions that address them.

Methods

Multi-stakeholder consensus conference and follow-up survey.

Results

From 31 risk factors to sustainable employment of persons with ABI or SCI identified in previous studies, nine were defined as most important to address with interventions. These risk factors either impacted the person, the work environment or service provision. Potential interventions to address these factors were proposed in mixed condition groups, of which ten were voted on as priority interventions. The follow-up survey revealed strong agreement on the intervention proposals, strong to moderate agreement on impact, but moderate to low feasibility, as most of the interventions were measures at the meso- (service) and macro- (legislation and state regulation) level.

Conclusions

Holding micro-level stakeholder conferences is a valuable method for identifying the most important risk factors to sustainable employment and for developing measures to address them. To implement measures that involve decisions at the meso- or macro-level, representatives from these levels of the healthcare and social system have to be involved.

Employment and accommodation needs and the effect of COVID-19 on men and women with traumatic brain injury

BACKGROUND

Traumatic brain injury (TBI) impacts an individual's workforce involvement post-injury. Support services and workplace accommodations that can help with work re-integration post-TBI may differ based on a person's sex and gender. The added impact of COVID-19 remains under-explored.

OBJECTIVE

We aimed to investigate the support services and workplace accommodation needs and the impact of COVID-19 on work and mental health for persons with TBI, considering sex and gender.

METHODS

A cross-sectional online survey was distributed. Descriptive and regression analyses were applied to uncover sex and gender differences, along with content analysis for open-ended responses.

RESULTS

Thirty-two persons with TBI (62% women, 38% men) participated. Physiotherapy, occupational therapy, and counselling services were indicated as the most needed services by women and men. Modified hours/days and modified/different duties were the most needed workplace accommodations. Mental challenges impacting well-being was a highlighted concern for both men and women. Women scored poorer on the daily activity domain of the Quality of Life after Brain Injury - Overall Scale (p = 0.02). Assistance with daily activities was highlighted by women for a successful transition to work, including housekeeping and caregiving. Men were more likely than women to experience change in employment status because of COVID-19 (p = 0.02). Further, a higher percentage of men expressed concern about the inability to pay for living accommodations, losing their job, and not having future job prospects.

CONCLUSION

Findings reveal important differences between men and women when transitioning to work post-TBI and emphasize the need for sex and gender considerations.

Vocational/educational prognosis in adolescents and young adults with acquired brain injury: a nationwide cohort study

OBJECTIVE

To determine prognostic factors for work ability and employment/educational status among young patients referred to outpatient neurorehabilitation clinics after an acquired brain injury.

METHODS

A nationwide cohort study of 471 15-30-year-old patients who attended an interdisciplinary clinical assessment and provided questionnaire data at baseline and after one year. The outcomes were the Work Ability Score (WAS, 0-10 (best)) and employment/educational status after one year. Prognostic performance was analyzed using univariable regression and multivariable Ridge regression in a five-fold cross-validated procedure.

RESULTS

Preinjury, 86% of the patients were employed, while the percentage had decreased to 55% at baseline and 52% at follow-up. The model, which included clinical measures of function, showed moderate prognostic performance with respect to WAS (R2=0.29) and employment/educational status (area under the curve (AUC)=0.77). Glasgow Outcome Scale Extended (R2=0.15, AUC=0.68) and the cognitive subscale of the Functional Independence Measure (R2=0.09, AUC=0.64), along with fatigue measured with the Multidimensional Fatigue Inventory (R2=0.15, AUC=0.60) were the single predictors with the highest predictive performance.

CONCLUSION

Despite generally high scores in motor and cognitive tests, only about half of the patients were employed at baseline and this proportion remained stable. Global disability, cognitive sequelae and fatigue had the highest prognostic performance.

Exploring employment following traumatic brain injury in persons who completed an insurer funded vocational rehabilitation program in Australia

PURPOSE

To extend the authors' previous research by investigating the maintenance of work performance over time and the long-term experience of employment following traumatic brain injury (TBI).

MATERIALS AND METHODS

Semi-structured interviews were conducted with a sample of 72 individuals with predominantly severe TBI, up to 10-years post-injury. Thematic analysis of transcribed interviews was conducted.

RESULTS

Four key themes were identified: brain injury influences on work performance and long-term employment; factors optimising long-term employment; and need for compromise and acceptance, which all impacted the final theme, quality of life outcome. While TBI-related difficulties such as fatigue, cognitive, and emotional difficulties still impacted work many years post-injury, work modifications and employer and vocational rehabilitation (VR) support were important factors optimising long-term employment. The timing of return to work (RTW) was also an important and potentially modifiable factor influencing work performance, which appeared to have long-term effects on the maintenance of employment. Support for acceptance of altered career goals is needed.

CONCLUSION

Findings support the need for early VR to facilitate employer contact, to maximise adjustment and preparation time before RTW, to educate both employees and employers and to implement work modifications to support continuing employment after TBI.Implications for rehabilitationThe maintenance of employment following TBI is of critical importance for financial independence, psychological and social well-being, and improved quality of life.Injury-related difficulties still impact work performance many years after injury requiring individuals with TBI to continue working in modified roles and for reduced hours over the long-term.Ongoing VR and employer support is needed to facilitate long-term work modifications and compensatory strategies to support work performance.Early VR involvement to facilitate employer contact and maximise adjustment and preparation time before returning to work is necessary to avoid the negative and potentially dire consequences of returning too early.Psychological support to facilitate acceptance of role changes and career compromises is also important.

The experience of employers of individuals with traumatic brain injury

OBJECTIVES

To understand the experience of employers of individuals with traumatic brain injury (TBI) who have received comprehensive vocational rehabilitation (VR), the factors involved in supporting an individual with TBI to return to work (RTW), and the support needs of employers.

METHODS

12 employers completed semi-structured interviews, which were recorded, transcribed, and analysed thematically.

RESULTS

Five main themes were identified: challenges and impact on employer, managing employee post-injury changes, looking after employee wellbeing, managing conflicting emotions, and utilizing sources of support. Although employers received support with operational challenges, findings suggest they were not prepared for the emotional journey. While they struggled to support employees through the difficult process of realizing they could no longer perform at their pre-injury level, employers strove to find appropriate roles and ensure wellbeing for their injured employees. Despite employers' endeavours, they felt this process was demoralizing for some employees.

CONCLUSIONS

Advising employers on operational as well as emotional support needs of both employees and employers is an ongoing challenge for VR providers. Although unsupportive employers were not well-represented in this sample, the study highlights the challenges faced and strategies used by employers who have a strong personal investment in the successful RTW of their employees.

Employment probability trajectories in hispanics over the 10 years after traumatic brain injury: A model systems study

BACKGROUND: Research has found that Hispanics with traumatic brain injury (TBI) have reduced functional outcomes compared to non-Hispanic Whites, including lower probabilities of post-injury employment. However, previous studies were cross-sectional, combined racial/ethnic minority groups, and did not examine the factors that predict return to work of Hispanics longitudinally. OBJECTIVE: To determine the demographic and injury-related predictors of employment probability trajectories during the first 10 years after TBI. METHODS: 1,346 Hispanics in the TBI Model Systems Database was included. Hierarchical linear modeling was used to examine baseline predictors of employment probability trajectories across this time period. RESULTS: Employment probability demonstrated a quadratic movement over time, with an initial increase followed by a plateau or slight decrease. Hispanics with TBI had higher employment probability trajectories if they had been younger at the time of injury, spent less time in posttraumatic amnesia, had greater years of education, had been employed at the time of injury, had higher annual earnings at the time of injury, and had experienced a non-violent mechanism of injury. CONCLUSION: Culturally adapted treatment programs with a focus on early intervention incorporating vocational rehabilitation and employment programs for Hispanics with TBI who present with these risk factors are needed.

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.

Developing a model of return to school: A Traumatic Brain Injury Model Systems study

OBJECTIVE

A common goal for those recovering from moderate to severe brain injury is to reengage in education or employment. There is significant overlap between the skills relevant for successful job and academic performance in high school and college, and many deficits reported after brain injury are consistent across young adults and adults. This study utilized a return to work (RTW) model framework to develop a model of return to school (RTS).

METHOD

Days of post-traumatic amnesia (PTA), length of stay (LOS), rehabilitation discharge Disability Rating Scale (DRS) scores, presence of pre-injury learning limitation, and educational level were used to predict RTS one-year post-injury in a student sample (N = 158, 58.8% white, 69.6% male) within the Traumatic Brain Injury Model Systems National Database.

RESULTS

The overall RTS rate for this sample was 62%. Logistic regression indicated that lower DRS discharge scores and being in high school pre-injury resulted in the best outcome.

CONCLUSION

Results showed partial support for the translation of RTW factors to a student sample; however, results may also favor the conceptual distinction in RTS versus RTW, which are elaborated. More outreach for college students may improve awareness of disability services, thereby heightening the future return rate.

Apathy Level, Disinhibition, and Psychiatric Conditions Are Related to the Employment Status of People With Traumatic Brain Injury

IMPORTANCE

An understanding of the potential prognostic factors as they relate to the employment status of people with traumatic brain injury (TBI) is necessary so that occupational therapy practitioners can provide the most effective treatment.

OBJECTIVE

To examine the impact of apathy, disinhibition, and psychiatric conditions on employment status after TBI.

DESIGN

An observational study conducted from March 2015 to March 2020.

SETTING

Cognitive dysfunction clinics associated with two general hospitals in Japan.

PARTICIPANTS

Japanese people of working age (N = 110, ages 18-65 yr) with TBI. Outcomes and Measures: As an outcome indicator, each participant's employment status was rated on a 3-point scale (i.e., 3 = regular employment, 2 = welfare employment [employed as a person with disabilities or undergoing vocational training in the Japanese welfare employment system, for which a worker is paid under either system], 1 = unemployment). Psychiatric, neuropsychological, and physical assessments were measured as explanatory variables. The impact of various factors on employment status was investigated using linear discriminant regression analysis.

RESULTS

The level of apathy, disinhibition, and incidence of psychiatric conditions after TBI, as well as age and years postinjury, were related to employment status. Conclusion and Relevance: Although this is a cross-sectional study, interventions for apathy and disinhibition, as well as management of psychiatric conditions, are recommended to help improve employment status among people with TBI. What This Article Adds: The employment status of people with TBI is related more to apathy, disinhibition, and psychiatric conditions than to intelligence, memory function, or executive function.

The relationship between cognition and vocational training outcome in patients with acquired brain injury: Contribution of Machine Learning

The aim of this study was to identify specific cognitive patterns related to long-term vocational training outcome. Records of twenty-eight patients who had benefited from a professional rehabilitation program were retrospectively processed. Screening through machine learning algorithms of patients' neuropsychological scores identified cognitive patterns related to both vocational training outcomes: succeeded or failed. These patterns were based on cognitive performance intervals even if the cognitive ability was not impaired. The cognitive pattern related to a successful vocational training included performance intervals on measures underlying verbal memory consolidation, visual memory incidental recall, problem solving and planning abilities. The cognitive pattern explaining failure of vocational training included performance intervals on tasks involving planning and problem solving abilities. From a comprehensive neuropsychological battery, memory and executive measures appeared to be the best attributes related to the vocational training outcome in patients with brain injury. Even with a cognitive functioning above the pathological cutoff, patients suffering from a brain injury could fail a vocational training. The attributes related to the vocational training outcome would be more a specific level of cognitive functioning rather than an interpretation of neuropsychological scores only based on a normal versus pathological distinction.

Two Ecological Tools for Testing Slowness of Information Processing in Italian Patients with Moderate-to-Severe Traumatic Brain Injury

Slowness of Information Processing (SIP) is frequently experienced after traumatic brain injury (TBI); however, the impact of SIP on everyday functioning may be underestimated by standard neuropsychological tests.

OBJECTIVE

we aimed to adapt two ecological instruments assessing SIP in Italian patients with moderate-to-severe TBI, as formerly proposed by Winkens and colleagues for persons with stroke, testing also its possible relation with other neuropsychological processes and functional outcomes.

METHOD

we performed an observational study on 37 patients with moderate-to-severe TBI and 35 demographically matched healthy controls, who underwent the Mental Slowness Observation Test (MSOT) and the Mental Slowness Questionnaire (MSQ), which had been adapted through a pilot study on independent sample of participants; extensive neuropsychological and functional evaluations were performed as well.

RESULTS

We found good clinical and psychometric properties of the Italian adaptation of the MSOT and MSQ; also, performance on MSOT significantly correlated with executive functions. Moreover, patients with TBI are significantly slower and less accurate than healthy controls on the MSOT, in particular in tasks with time limits. Even if the subjective feeling of SIP does not differ between patients and controls, we found a significant correlation between MSQ and MSOT. Finally, the performances on the MSOT correlated with measures of functional outcome and community integration.

CONCLUSIONS

the results support the use of the MSOT and the MSQ to measure SIP in an ecological fashion in patients with TBI, so that specific treatments for persons with acquired brain injury can be prescribed.

Improving Outcomes for Work-Related Concussions: A Mental Health Screening and Brief Therapy Model

OBJECTIVE

This study assessed the efficacy of a neurocognitive screening evaluation and brief therapy model to improve RTW outcomes for workers who experienced mild head injuries.

METHODS

Patients referred were evaluated using a neurocognitive and psychological screening battery. Work-focused cognitive behavioral therapy was provided when appropriate, addressing the role of negative emotional adjustment and functional sleep disturbance in prolonging recovery.

RESULTS

Average time to RTW was 7 weeks post-evaluation, despite workers being off an average of 10 months between injury and referral dates. Overall, 99% were released to full-duty work without restrictions or accommodations.

CONCLUSIONS

This study demonstrates the favorable outcomes achieved via a structured, clinically driven program for workers who experience head-involved injuries, validating previous research on the importance of recognizing the role of psychological factors in prolonging concussion recovery.

Factors associated with sustaining work after an acquired brain injury: a scoping review

PURPOSE

Maintaining work in the long term represents a major challenge for people with acquired brain injury (ABI) as evidenced by a high rate of premature labour market dropouts. The present study aimed to compile factors associated with working in the long term after sustaining an ABI.

MATERIALS AND METHODS

We carried out a scoping review synthesizing quantitative and qualitative research conducted between 2000 and 2021. Databases searched comprised PubMed, CINAHL Complete, PsycINFO, Scopus, and Web of Science.

RESULTS

Ten quantitative and nine qualitative studies were included, all but one from high-resource countries. Quantitative research predominantly comprised longitudinal follow-ups on individuals' work status several years post ABI onset, showing an effect of injury-related and sociodemographic factors. Qualitative studies mostly dealt with work maintenance and revealed a key role of cognitive difficulties, psychological personal factors (e.g., adequate coping strategies) and environmental factors (e.g., flexible work schedules, supportive colleagues).

CONCLUSIONS

The factors identified in our review should receive particular attention in vocational integration and job retention programs to support work participation of people with ABI in the long term. There is a need for measures that regularly monitor and promote a good match between individuals and their work environment.Implications for RehabilitationPeople with acquired brain injury (ABI) often have long-lasting and invisible injury-related difficulties that hamper their labour market participation.Factors identified as positively associated with working in the long term, such as coping strategies and self-awareness, should be strengthened.Future interventions should educate affected persons, employers and health care professionals about long-lasting injury-related difficulties and promote a supportive work environment for people with ABI.Prolonged availability of vocational services could be beneficial for supporting work maintenance of people with ABI.

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.

Common Symptoms of Mild Traumatic Brain Injury and Work Functioning of Active-Duty Service Members with a History of Deployment

This study used data from the Military Health System Data Repository to examine the association between mild traumatic brain injuries (mTBI) and work functioning such as work duty limitations, hospital emergency room visits and inpatient admissions for active-duty service members (ADSMs). Further, this study assessed the role that common symptoms of mTBI play in work functioning. Multivariate results showed that having a mTBI diagnosis is not a major factor that results in being "released with work duty limitations". However, findings from these regression models also showed that the interaction of mTBI with cognitive and linguistic symptoms resulted in odds of 3.63 (CI: 1.40-9.36, p < 0.01) for being "released with work duty limitations" and odds of 4.98 (CI: 1.16-21.39, p < 0.05) for having any emergency department visits compared to those with no diagnosis of mTBI and none of these symptoms. Additionally, the interaction of mTBI with sleep disturbance and chronic pain showed odds of 2.72 (CI: 1.31-5.65, p < 0.01) and odds of 11.56 (CI: 2.65-50.44, p < 0.01) for being "released with work duty limitations" compared to those with no diagnosis of TBI and none of these symptoms, respectively. Further research is needed to investigate the association between mTBI and duration of time off work to provide a comprehensive understanding of the effect of mTBI on work functioning in the Military Health System.

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.

Vocational rehabilitation to enhance return to work after trauma (ROWTATE): protocol for a non-randomised single-arm mixed-methods feasibility study

Background

Traumatic injuries are common amongst working-age adults. Survivors often experience physical and psychological problems, reduced quality of life and difficulty returning to work. Vocational rehabilitation improves work outcomes for a range of conditions but evidence of effectiveness for those with traumatic injuries is lacking. This study assesses feasibility of delivering a vocational rehabilitation intervention to enhance return to work and improve quality of life and wellbeing in people with at least moderate trauma to inform design of a definitive randomised controlled trial (RCT).

Methods

Non-randomised, single-arm, multi-centre mixed-methods feasibility study with nested case studies and qualitative study. The case studies comprise interviews, observations of clinical contacts and review of clinical records. The qualitative study comprises interviews and/or focus groups. Participants will be recruited from two UK major trauma centres. Participants will comprise 40 patients aged 16–69 with an injury severity score of > 8 who will receive the intervention and complete questionnaires. Interviews will be conducted with 10 patients and their occupational therapists (OTs), clinical psychologists (CPs), employers and commissioners of rehabilitation services. Fidelity will be assessed in up to six patients by observations of OT and CP—patient contacts, review of patient records and intervention case report forms. OT and CP training will be evaluated using questionnaires and competence to deliver the intervention assessed using a team objective structured clinical examination and written task. Patients participating in and those declining participation in the study will be invited to take part in interviews/focus groups to explore barriers and facilitators to recruitment and retention. Outcomes include recruitment and retention rates, intervention fidelity, OT and CP competence to deliver the intervention, experiences of delivering or receiving the intervention and factors likely to influence definitive trial delivery.

Discussion

Effective vocational rehabilitation interventions to enhance return to work amongst trauma patients are urgently needed because return to work is often delayed, with detrimental effects on health, financial stability, healthcare resource use and wider society. This protocol describes a feasibility study delivering a complex intervention to enhance return to work in those with at least moderate trauma.

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.

Early Predictors of Employment Status One Year Post Injury in Individuals with Traumatic Brain Injury in Europe

Sustaining a traumatic brain injury (TBI) often affects the individual’s ability to work, reducing employment rates post-injury across all severities of TBI. The objective of this multi-country study was to assess the most relevant early predictors of employment status in individuals after TBI at one-year post-injury in European countries. Using a prospective longitudinal non-randomized observational cohort (The Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) project), data was collected between December 2014–2019 from 63 trauma centers in 18 European countries. The 1015 individuals who took part in this study were potential labor market participants, admitted to a hospital and enrolled within 24 h of injury with a clinical TBI diagnosis and indication for a computed tomography (CT) scan, and followed up at one year. Results from a binomial logistic regression showed that older age, status of part-time employment or unemployment at time of injury, premorbid psychiatric problems, and higher injury severity (as measured with higher Injury severity score (ISS), lower Glasgow Coma Scale (GCS), and longer length of stay (LOS) in hospital) were associated with higher unemployment probability at one-year after injury. The study strengthens evidence for age, employment at time of injury, premorbid psychiatric problems, ISS, GCS, and LOS as important predictors for employment status one-year post-TBI across Europe.

Aspects of Executive Dysfunction and Racial/Ethnic Minority Status Are Associated With Unemployment Duration in Veterans With a History of Mild-to-Moderate Traumatic Brain Injury

OBJECTIVE

To examine demographic, psychiatric symptom, and neuropsychological performance factors associated with duration of unemployment in Iraq/Afghanistan Veterans with a history of mild-to-moderate traumatic brain injury (TBI).

DESIGN

Cross-sectional, secondary data analysis of baseline measures in a supported employment study.

SETTING

VA medical center.

PARTICIPANTS

Participants (N=50) were veterans with a history of mild-to-moderate TBI who were unemployed, stating a goal of returning to work, and had documented impairment in at least 1 neuropsychological domain. Participants were referred from VA vocational and assessment-based clinics.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Duration of unemployment, neuropsychological, and psychiatric symptom assessments.

RESULTS

Bivariate correlations revealed that longer duration of unemployment was associated with greater posttraumatic stress disorder (P<.10) and depressive (P<.05) symptom severity, worse executive functioning (P<.05), and racial/ethnic minority status (P<.05). A multiple linear regression analysis including these independent variables explained 26.5% of the variance in duration of unemployment. Worse executive functioning, specifically reasoning and set-shifting, and minority status were each associated with longer duration of unemployment in the context of multiple independent variables.

CONCLUSIONS

Our results underscore the importance of objective assessment of cognitive functioning in job-seeking Veterans with TBI histories. It may be useful to target aspects of executive functioning in vocational rehabilitation interventions and to provide additional assistance to Veterans from racial/ethnic minority groups.

Sudden Cardiac Arrest Survivorship: A Scientific Statement From the American Heart Association

Cardiac arrest systems of care are successfully coordinating community, emergency medical services, and hospital efforts to improve the process of care for patients who have had a cardiac arrest. As a result, the number of people surviving sudden cardiac arrest is increasing. However, physical, cognitive, and emotional effects of surviving cardiac arrest may linger for months or years. Systematic recommendations stop short of addressing partnerships needed to care for patients and caregivers after medical stabilization. This document expands the cardiac arrest resuscitation system of care to include patients, caregivers, and rehabilitative healthcare partnerships, which are central to cardiac arrest survivorship.

Traumatic Brain Injury Caused by Work Accidents: How can Occupational and Vocational Recovery be Achieved?

Issues connected with the reintegration of individuals affected by severe brain injury are numerous and complex. Extensive data indicate the effectiveness of treatments based on an holistic approach, which integrates medical interventions with social programmes and offers continuity, leading to the rapid achievement of independent living outcomes and return to work. In Italy, extensive resources are available for the clinical and rehabilitation management of individuals affected by traumatic brain injury in the acute and post-acute phase, but there are only a few organized services to support the reintegration phase. This paper describes a model created via a 2-year collaboration between the National Institute for Insurance against Accidents at Work (INAIL) in Rome and the National Federation of Traumatic Brain Injury Associations (FNATC). The combined effort of these organizations led to the development of an Italian Model of Vocational Rehabilitation (IMoVR), which was exportable to all 20 Italian Regions. Due to the experience gained by a few avant-garde teams, IMoVR was used to pioneer an approach characterized by structured phases and actions aimed at designing high-quality interventions, and at monitoring their long-term effectiveness. These teams comprised experts in different areas, including: forensic doctors, social workers, administrative managers of INAIL, neuropsychologists, psychotherapists, educators working in associations registered with FNATC, all of whom are members of a service network that had already activated small individual vocational projects. In total, the collaboration comprised 42 pro-fessionals working in 7 Italian cities: Ancona, Arezzo, Ferrara, Milano, Pordenone, Rimini and Vicenza.

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.

Impact of interventions on work-related outcomes for individuals with musculoskeletal injuries after road traffic crash: a systematic review protocol

BACKGROUND

Musculoskeletal injuries are the most common non-fatal injury from road traffic crashes. Even when the injuries are mild, they can cause pain which can affect return to work rates and work ability post-crash. Workplace output losses are the biggest cost from traffic crash-related injuries. There is a need to identify effective interventions that can improve work-related outcomes (e.g. time to return to work, sick leave, and work ability) in this group and a need to understand the intervention components, external factors, and participant characteristics that may be associated with improvement.

METHODS

A systematic review will be conducted using seven databases and search terms related to road traffic crash, musculoskeletal injury, work-related outcomes, and study design. Intervention studies will be eligible if they report on at least one work-related outcome, include adults with a traffic crash-related musculoskeletal injury (e.g. fracture or whiplash), include a comparison group, and are written in English. Interventions can be medical, therapeutic, work-based, multicomponent, or other. Two researchers will independently screen titles and abstracts, review full texts for inclusion in the review, and perform the data extraction. The main outcomes of the review will be time until return to work and duration of sick leave. The results will be narratively described, with meta-analyses conducted where possible.

DISCUSSION

This review will explore the effectiveness of interventions in individuals with traffic crash-related musculoskeletal injury on work-related outcomes and will act as a useful source for researchers, policy makers, and stakeholders when developing and implementing interventions in this group.

Long-term employment outcomes following moderate to severe traumatic brain injury: a systematic review and meta-analysis

Background: Returning to employment following moderate to severe traumatic brain injury (msTBI) is critical for a survivor's well-being, yet currently there are no systematic reviews that comprehensively describe employment outcomes following msTBI. The objective of this study was to systematically synthesize literature on employment outcomes following msTBI.Methods: Original studies published through April 2018 on MEDLINE/PubMed, PsychINFO, and CINAHL were eligible if the objective was to investigate employment outcomes following msTBI; outcome was measured ≥1 year; participants were ≥15; and size was ≥60. Post-injury employment prevalence and return to pre-injury level of work were summarized through meta-analysis.Results: Of 38 eligible studies, post-injury employment prevalence was most often reported (n = 35), followed by job stability (n = 6), and return to pre-injury level of work (n = 4). Overall post-injury employment prevalence was 42.2%; whereas the return-to-previous-work prevalence was 33.0%. Post-injury employment prevalence appeared to increase over time, from 34.9% at 1 year to 42.1% up to 5 years and 49.9% beyond 5 years.Conclusion: Nearly half of individuals with msTBI were employed post-injury, yet only a third returned to pre-injury level of work. Future researchers are recommended to standardize employment outcome measures to enable better comparison of outcomes across 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.

A Detailed Overview of Long-Term Outcomes in Severe Traumatic Brain Injury Eight Years Post-injury

Background and aims: Severe traumatic brain injury is a leading cause of acquired persistent disabilities, and represents an important health and economic burden. However, the determinants of long-term outcome have rarely been systematically studied in a prospective longitudinal study of a homogeneous group of patients suffering exclusively from severe TBI

Methods: Prospective observational study of an inception cohort of adult patients with severe traumatic brain injury in the Parisian area (PariS-TBI). Outcome was assessed with face-to-face interview 8 years after Traumatic Brain Injury, focusing on impairments, activity limitations, and participation restriction.

Results: Five hundred and four patients were included between 2005 and 2007. At 8-year follow-up, 261 patients were deceased, 128 were lost to follow-up, 22 refused to participate, and 86 were finally evaluated. Age, gender, initial injury severity did not significantly differ between evaluated patients and lost to follow-up, but the latter were more frequently students or unemployed. Mean age was 41.9 (SD 13.6), 79% were male, median initial Glasgow Coma Scale Score was 6. The most frequent somatic complaints concerned balance (47.5%), motricity (31%), and headaches (36%), but these were less frequent than cognitive complaints (Memory 71%, Slowness 68%, Concentration 67%). According to the Hospital Anxiety and Depression Scale (HADS), 25 % had a score >8 for anxiety and 23.7% for depression. According to the Extended Glasgow Outcome Scale, 19.8% remained severely disabled, 46.5% moderately disabled, 33.7% had a good recovery. Older age, longer education duration, lower functional status upon intensive care discharge, and more severe 8-year dysexecutive problems were significantly associated with a lower Extended Glasgow Outcome Scale score in multivariable analysis. At 8 years, 48.7% of patients were employed in a productive job. Of those, 38% declared a salary loss since traumatic brain injury. Unemployment was significantly associated with lower 1-year GOSE score and more severe 8-year dysexecutive problems.

Conclusions: These results from an inception cohort study highlight the fact that long-term outcome after severe TBI is determined by a complex combination of injury-related, demographic and neuropsychological factors. Long after the injury, persisting impairments still interfere with social integration, and participation.

Applying bifactor modelling to improve the clinical interpretive values of Functional Independence Measure in adults with acquired brain injury

Purpose: To apply a modern robust approach, bifactor modeling, to critically examine psychometric properties of Functional Independence Measure (FIM) in adults with acquired brain injury and to propose a solution to improve the clinical interpretive values of the FIM to inform policy and clinical practice.Methods: The data came from a state-wide specialist in-patient brain injury rehabilitation service in Queensland, Australia for adults with acquired brain injury and discharged between 2012 and 2017. The sample included 457 people. Three measurement models (unidimensional, correlated first-order and bifactor) for FIM were tested using confirmatory factor analysis with structural equation modeling. Then, model-based reliability and incremental validity were assessed.Results: The bifactor model best fit the data. When operationalized as latent factors under structural equation modeling framework, general care burden had a large predictive effect, while Motor and Cognitive showed medium and small predictive effects respectively on rehabilitation length of stay.Conclusions: The total score of FIM was a reliable measure of general care burden, while the subscale scores were not. A solution is to apply a bifactor modeling approach based on structural equation modeling to disentangle the unique variance attributable to Motor and Cognitive factors. In the structural equation modeling framework, the FIM demonstrated good incremental validity to inform policy and clinical practice.Implications for rehabilitationClinicians and researchers can confidently use FIM total score in adults with acquired brain injury.The current study proposed an alternative solution to the poor reliability of Motor and Cognitive scores, that is, by applying a bifactor modeling approach, the unique contributions of the Motor and Cognitive factors can be examined.The current study has demonstrated the strengths of bifactor modeling in the robust validation and interpretation of FIM to better inform clinical practice and policy decision-making.The current study has the potential to make an important contribution to enhance more equitable decision-making in the areas of national benchmarking of rehabilitation outcomes and other program eligibility criteria and funding allocation.

Indicators of long-term return to work after severe traumatic brain injury: A cohort study

BACKGROUND

Return to work (RTW) is a major objective in the rehabilitation of individuals with severe traumatic brain injury (TBI). Implications for long-term occupational integration (beyond 5 years) have rarely been studied.

OBJECTIVE

The objective was to assess long-term RTW and the associated factors after severe TBI.

MATERIAL AND METHODS

Retrospective analysis of a cohort of individuals 16 to 60 years old admitted to hospital after severe TBI from 2005 to 2009 and followed prospectively. Medical and occupational data were collected from medical files and by systematic telephone interview to assess outcome at a minimum of 6 years post-trauma. Factors associated with RTW were investigated by multivariable regression analysis, estimating prevalence ratios (PRs) and 95% confidence intervals (CIs). A proportional hazards model was used to study RTW delay, estimating hazard ratios (HRs).

RESULTS

Among the 91 individuals included (mean [SD] age 28.5 [11.3] years; 79% male), 63.7% returned to work after a mean of about 20 months, and 57.1% were still working at the time of the survey. Factors significantly associated with RTW on multivariable analysis were higher educational level (adjusted PR, 1.53; 95% CI, 1.15 to 2.03), absence of motor disability (adjusted PR, 1.82; 1.12 to 2.95) and behavioural disorder (adjusted PR, 1.26; 1.01 to 1.60), as well as disabled worker status (adjusted PR, 1.26; 1.01 to 1.60) (likelihood of the multivariate analysis model 53.1). Delayed RTW was associated with health insurance payments (adjusted HR, 0.40; 95% CI, 0.22 to 0.71), motor disability (adjusted HR, 0.34; 0.15 to 0.76), low educational level (adjusted HR, 2.20; 1.06 to 4.56) and moderate disability on the Extended Glasgow Outcome Scale (adjusted HR, 0.49; 0.27 to 0.91) (likelihood of the multivariate analysis model 335.5).

CONCLUSION

Individuals with the most severe TBI are able to RTW and remain in work. This study highlights the multiple determinants involved in RTW and the role of socioenvironmental factors.

Employment outcome four years after a severe traumatic brain injury: results of the Paris severe traumatic brain injury study

OBJECTIVE

To describe employment outcome four years after a severe traumatic brain injury by the assessment of individual patients' preinjury sociodemographic data, injury-related and postinjury factors.

DESIGN

A prospective, multicenter inception cohort of 133 adult patients in the Paris area (France) who had received a severe traumatic brain injury were followed up postinjury at one and four years. Sociodemographic data, factors related to injury severity and one-year functional and cognitive outcomes were prospectively collected.

METHODS

The main outcome measure was employment status. Potential predictors of employment status were assessed by univariate and multivariate analysis.

RESULTS

At the four-year follow-up, 38% of patients were in paid employment. The following factors were independent predictors of unemployment: being unemployed or studying before traumatic brain injury, traumatic brain injury severity (i.e., a lower Glasgow Coma Scale score upon admission and a longer stay in intensive care) and a lower one-year Glasgow Outcome Scale-Extended score.

CONCLUSION

This study confirmed the low rate of long-term employment amongst patients after a severe traumatic brain injury. The results illustrated the multiple determinants of employment outcome and suggested that students who had received a traumatic brain injury were particularly likely to be unemployed, thus we propose that they may require specific support to help them find work. Implications for rehabilitation Traumatic brain injury is a leading cause of persistent disablity and can associate cognitive, emotional, physical and sensory impairments, which often result in quality-of-life reduction and job loss. Predictors of post-traumatic brain injury unemployment and job loss remains unclear in the particular population of severe traumatic brain injury patients. The present study highlights the post-traumatic brain injury student population require a close follow-up and vocational rehabilitation. The study suggests that return to work post-severe traumatic brain injury is frequently unstable and workers often experience difficulties that caregivers have to consider.
