A systematic review and meta-analysis of return to work after mild Traumatic brain injury

Vocational Rehabilitation Outcomes From the U.K. Working Out Program: Characterizing the New Vocational Roles Obtained by People With Acquired Brain Injuries

IMPORTANCE

Supporting acquired brain injury (ABI) survivors to find new vocational roles is a critical aspect of vocational rehabilitation. However, it is rarely provided in the United Kingdom and U.K.-based research in this area is lacking.

OBJECTIVE

To characterize the new vocational roles obtained by ABI survivors who accessed a specialist service (Working Out program) providing rehabilitation and supported employment.

DESIGN

Retrospective descriptive statistical analysis of routinely collected clinical data.

SETTING

Community Head Injury Service, Buckinghamshire Healthcare National Health Service Trust, United Kingdom.

PARTICIPANTS

ABI survivors who accessed the Working Out program between 2005 and 2023 and who started a new vocational role during this period.

OUTCOMES AND MEASURES

Role type, role status, industry.

RESULTS

ABI survivors (N = 278; M age = 41.75 yr, SD = 13.09; 24.82% female) obtained a new vocational role. It took on average 1.98 yr (SD = 2.35, range = 0-14) to find an initial new role. Survivors obtained on average 2.79 new vocational roles each (SD = 2.13, range = 1-15). Of the 767 roles for which relevant data were available, 332 (43.29%) were paid, 386 (50.33%) were voluntary, and 49 (6.39%) were education or training roles. The most frequent industry in which a new vocational role was obtained was administrative and support service activities.

CONCLUSIONS AND RELEVANCE

U.K. ABI survivors may be supported to find new vocational roles. However, rehabilitation plus supported employment interventions may be required for an extended duration given the complexity of ABI as a chronic health condition and challenges associated with finding new roles. Plain-Language Summary: People with brain injuries often need support to find new vocational roles after their injury. However, this type of support is rarely provided in the United Kingdom, and U.K.-based research in this area is limited. We analyzed data from a U.K. clinical service that provides rehabilitation and helps people with brain injuries find new jobs. We showed that many people with brain injuries successfully found at least one new job, and many of these new jobs were paid. However, it often took a substantial period of time for them to find a new job.

Sickness absence > 14 days following mild traumatic brain injuries from traffic accidents: a Swedish nationwide register study

BACKGROUND

Mild traumatic brain injuries (mTBI), including concussions, following traffic accidents is common. How often these injuries lead to sickness absence (SA) among working aged individuals is however insufficiently studied. Thus, the aim of this study was to examine frequency of new SA following mTBI sustained in a road traffic environment and its associations with sociodemographic and injury-related factors.

METHOD

Nationwide population-based register study. Working aged individuals (18-63), living in Sweden, who in 2014 to 2016 acquired an mTBI in a traffic accident were included based on in- and specialised out-patient health care records. Information on SA (> 14 days), disability pension, pre-injury factors (age, sex, education, marital status, type of living area, country of birth, income from work) as well as injury-related factors (type of road user, in- or outpatient health care) were used in analyses of risk factors for a new SA-spell. Odds ratios (ORs), both crude and adjusted, with 95% confidence intervals (CIs) were estimated with logistic regression.

RESULTS

6073 individuals were identified. 12% had a new SA spell after injury. Sociodemographic risk factors were female sex, older age and being born outside Sweden. Car occupants had higher ORs for new SA, compared to pedestrians, bicyclists, and other road users, and was also associated with longer duration spells (> 90 days). Having received in-patient health care was associated with an OR of 3.7 for new SA compared to those only receiving out-patient health care (including emergency department visits). Having received in-patient health care was also associated with longer duration spells.

CONCLUSION

A traffic related mTBI is most often a benign injury, seldom resulting in a new SA spell of longer duration. When it does, it is more likely to involve car occupants, and those who have required in-patient health care.

Virtual reality and cognitive function rehabilitation after traumatic brain injury: a systematic review

Traumatic Brain Injury (TBI) is the leading cause of injury-related death worldwide. In recent years, Virtual Reality (VR) has emerged as a promising diagnostic and treatment tool capable of improving Cognitive Function (CF) after TBI. We sought to review the literature on this issue systematically. Web of Science, PubMed and PsycINFO were screened for relevant literature. Only randomized control trials whereby TBI-affected individuals underwent VR training and control groups received standard rehabilitative care were included. Screening, quality appraisal and data extraction were conducted by independent reviewers using a standardized protocol. Six studies of ~300 participants met the inclusion criteria and showed that both groups improved their overall CF post-intervention. However, non-immersive and semi-immersive VR groups had markedly better scores in all of the cognitive domains measured when compared to non-VR groups. VR is a potent post-TBI rehabilitative tool that can improve CF in this population and facilitate the return-to-work process. Future studies should adopt a similar design yet use fully immersive VR to enhance CF potentially to a greater degree.

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.

Occupational therapy interventions in facilitating return to work in patients with traumatic brain injury: A systematic review

BACKGROUND

Returning to work is one of the common challenges faced by survivors of traumatic brain injury following their injury. A few reviews to date have examined the occupational therapy interventions related to return-to-work post TBI.

OBJECTIVE

To examine the interventions that fall under the purview of the field of occupational therapy in facilitating return to work post mild, moderate, or severe traumatic brain injury.

METHODS

The following databases were searched: CINAHL, Ovid, PsychInfo, PubMed, & Scopus. Fifteen articles met the inclusion criteria (articles published within the past 10 years, adults, & received rehabilitation services for return to work). The Preferred Reporting Items for Systematic Reviews and Meta Analyses was used to guide this review.

RESULTS

The most effective intervention approaches that fall under the purview of occupational therapy practice to facilitate return to work in individuals with traumatic brain injury included the use of (i) vocational and work hardening rehabilitation interventions, (ii) a multidisciplinary approach to care, (iii) mental health and cognition focused interventions, and (iv) the Model of Occupational Self Efficacy. Interventions must consider both client and work-related factors to ensure successful outcomes.

CONCLUSIONS

The articles included in this review provided moderate level evidence that multidisciplinary and holistic approaches lead to successful return to work and community reintegration outcomes for individuals with traumatic brain injury. Focusing on client and work-related factors through vocational rehabilitation, cognitive and mental health interventions, and client-centered models of care is recommended to yield better return to work outcomes for traumatic brain injury survivors.

Barriers, Facilitators, and Requirements for a Telerehabilitation Aftercare Program for Patients After Occupational Injuries: Semistructured Interviews With Key Stakeholders

BACKGROUND

Patients with occupational injuries often receive multidisciplinary rehabilitation for a rapid return to work. Rehabilitation aftercare programs give patients the opportunity to help patients apply the progress they have made during the rehabilitation to their everyday activities. Telerehabilitation aftercare programs can help reduce barriers, such as lack of time due to other commitments, because they can be used regardless of time or location. Careful identification of barriers, facilitators, and design requirements with key stakeholders is a critical step in developing a telerehabilitation aftercare program.

OBJECTIVE

This study aims to identify barriers, facilitators, and design requirements for a future telerehabilitation aftercare program for patients with occupational injuries from the perspective of the key stakeholders.

METHODS

We used a literature review and expert recommendations to identify key stakeholders. We conducted semistructured interviews in person and via real-time video calls with 27 key stakeholders to collect data. Interviews were transcribed verbatim, and thematic analysis was applied. We selected key stakeholder statements about facilitators and barriers and categorized them as individual, technical, environmental, and organizational facilitators and barriers. We identified expressions that captured aspects that the telerehabilitation aftercare program should fulfill and clustered them into attributes and overarching values. We translated the attributes into one or more requirements and grouped them into content, functional, service, user experience, and work context requirements.

RESULTS

The key stakeholders identified can be grouped into the following categories: patients, health care professionals, administrative personnel, and members of the telerehabilitation program design and development team. The most frequently reported facilitators of a future telerehabilitation aftercare program were time savings for patients, high motivation of the patients to participate in telerehabilitation aftercare program, high usability of the program, and regular in-person therapy meetings during the telerehabilitation aftercare program. The most frequently reported barriers were low digital affinity and skills of the patients and personnel, patients' lack of trust and acceptance of the telerehabilitation aftercare program, slow internet speed, program functionality problems (eg, application crashes or freezes), and inability of telerehabilitation to deliver certain elements of in-person rehabilitation aftercare such as monitoring exercise performance. In our study, the most common design requirements were reducing barriers and implementing facilitators. The 2 most frequently discussed overarching values were tailoring of telerehabilitation, such as a tailored exercise plan and tailored injury-related information, and social interaction, such as real-time psychotherapy and digital and in-person rehabilitation aftercare in a blended care approach.

CONCLUSIONS

Key stakeholders reported on facilitators, barriers, and design requirements that should be considered throughout the development process. Tailoring telerehabilitation content was the key value for stakeholders to ensure the program could meet the needs of patients with different types of occupational injuries.

Return to work in persons with persistent postconcussion symptoms: a survey study examining the perspectives of employees and managers

OBJECTIVE

To examine challenges in return to work (RTW) for persons with persistent postconcussion symptoms (PPCS) experienced by the affected employees and their managers.

METHODS

A survey of employees (S-E) and two surveys of managers (S-M1, S-M2) executed 4 months apart to capture the time perspective. Inclusion: Adults aged 18-66 with PPCS > 4 weeks, employed at the time of mTBI who returned to work within the previous year. Managers involved in their RTW process.

OUTCOME MEASURES

Work status, working hours, work functioning (Work Role Functioning Questionnaire, WRFQ), work productivity.

RESULTS

Ninety-two employees and 66 managers were recruited. Three-fourths of the employees had returned to work but only one-third worked under similar conditions. Weekly working hours decreased from 36,3 hours (SD = 10,5) before mTBI to 17,6 hours (SD = 9,7). Employees had difficulties with tasks 43% of time (WRFQ). They needed more breaks, struggled with multitasking and work speed. About 65.9% experienced affected work productivity. Managers reported lack of knowledge and difficulties assessing the number of working hours and suitable tasks.

CONCLUSIONS

Most employees returned to work but only a minority worked under similar conditions as before mTBI. Employees and managers struggled to estimate workload. The affected employees and their workplaces need a long-term RTW support.

The relationship between prognostic factors and patient satisfaction with performance of self-identified goals following interdisciplinary mild traumatic brain injury rehabilitation

BACKGROUND

Individuals with persistent symptoms following a mild traumatic brain injury (mTBI) demonstrate improved satisfaction with their performance of self-identified rehabilitation goals after completing a combined occupational therapy and physiotherapy group intervention. However, the relationship between factors associated with developing persistent symptoms following an mTBI and satisfaction with their performance of self-identified goals after completing an intervention are unknown.

OBJECTIVE(S)

To evaluate whether factors associated with developing persistent symptoms influence satisfaction with the performance of self-identified goals after completing a combined occupational therapy and physiotherapy group intervention.

METHODS

During intake assessments, individuals with persistent mTBI symptoms completed the satisfaction section of the Canadian Occupational Performance Measure (COPM-S), the Rivermead Post-Concussion Symptom Questionnaire (RPQ), and the Generalized Anxiety Disorder Seven-Item Scale (GAD-7). Participants re-rated their satisfaction with performance of self-identified goals using the COPM-S during their discharge assessment. The influence of age, sex, days since injury, education, mechanism of injury, baseline COPM-S, GAD-7, and RPQ scores on goal satisfaction ratings were analyzed using a binomial logistic regression.

RESULTS

One hundred and ninety-eight individuals (44.7 ± 13.6 years old) were included in this study, and 92% experienced a clinically important improvement in their goal satisfaction ratings after completing the intervention. Neither age, sex, days since injury, education, mechanism of injury, baseline COPM-S, GAD-7, or RPQ scores significantly influenced satisfaction with performance of self-identified goals.

CONCLUSIONS

Factors associated with developing persistent symptoms following an mTBI did not influence goal satisfaction after completing a combined physiotherapy and occupational therapy group intervention.

Silent Struggles: Traumatic Brain Injuries and Mental Health in Law Enforcement

OBJECTIVE

To determine the prevalence of head injuries (HIs), posttraumatic stress disorder (PTSD), and depressive symptoms in law enforcement officers (LEOs) and (2) the association between HIs and psychological health conditions.

SETTING

County-level survey administered via Research Electronic Data Capture.

PARTICIPANTS

A total of 381 LEOs completed the survey (age = 43 ± 11 years; 40 [11%] females; time as LEO = 1-50 years, median = 15 years).

DESIGN

Cross-sectional study.

MAIN MEASURES

We examined the prevalence of HIs (the Ohio State University Traumatic Brain Injury Identification Method), PTSD (PTSD Checklist-Civilian [PCL-C]), and depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]). We used Mann-Whitney U and chi-square analyses to compare PTSD and depressive symptoms between those with and without a HI history.

RESULTS

There were 282 (74%) participants who reported a lifetime history of 1 or more HIs; 116 (30%) sustained 1 or more HIs on the job. PCL-C scores ranged 17 to 85 (median = 27); 33 (10%) participants met or exceeded the clinical cutoff score of 50 to indicate a positive PTSD screening. Participants with a HI history (median = 29) had higher PCL-C scores than those with no HI history (median = 24; P < .001), but the proportion of participants who met the clinical cutoff for PTSD was not different between those with ( n = 28, 11%) and without ( n = 5, 5%) a HI history (X 2  = 2.52, P = .112, odds ratio = 2.18; 95% confidence interval, 0.82-5.83). PHQ-9 scores ranged 0 to 20 (median = 3); 124 (36%) participants reported mild or greater depressive symptoms. Participants with a HI history (median = 3) had higher depressive symptoms than those with no HI history (median = 2; P = .012). The proportion of participants with mild or greater depressive symptoms was higher among those with a HI history ( n = 99, 39%) than without ( n = 25, 27%; X 2  = 4.34, odds ratio = 1.74; 95% confidence interval, 1.03-2.93).

CONCLUSION

HIs are prevalent in LEOs, which may have consequences for their performance, well-being, and career longevity. PTSD and depressive symptoms are higher in those with a HI history, suggesting LEOs need better traumatic brain injuries and mental health resources.

mTBI evaluation, management, and referral to allied healthcare: practices of first-line healthcare professionals

PRIMARY OBJECTIVE

To gain an understanding of current evaluation practices, post-injury recommendations, and referrals to allied healthcare professions (AHP) by first-line healthcare professionals (FHPs) providing care for people with mild traumatic brain injury (mTBI).

RESEARCH DESIGN

Survey study.

METHODS AND PROCEDURES

Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including Likert scale and free response question relating to mTBI evaluation, management, and referral practices.

MAIN OUTCOMES AND RESULTS

FHPs surveyed reported being confident in their ability to evaluate patients with suspected mTBI, relying most heavily on patient-reported symptoms and physical signs as methods of evaluation. Most FHPs reported making recommendations to compensate for the symptoms experienced following mTBI diagnosis. In contrast, FHPs expressed challenges in the evaluation and management of symptoms associated with mTBI along with limited knowledge of and referrals to AHPs.

CONCLUSIONS

Overall, FHPs feel confident in the diagnosis of mTBI but experience assessment and management challenges. AHPs are underutilized on mTBI management teams calling for a need for multidisciplinary collaboration on research, education, and rehabilitation efforts to optimally care for people experiencing mTBI symptoms.

Labour market attachment dynamics in patients with concussion: a Danish nationwide register-based cohort study

BACKGROUND

Concussion may lead to persisting post-concussive symptoms affecting work ability and employment. This study examined the transitions between labour market states an individual can experience after the acute phase of concussion. The aim was to describe the incidence of favourable and adverse transitions between different labour market states (e.g., employment, sick leave) in relation to socioeconomic and health characteristics in individuals with concussion relative to matched controls.

METHODS

This Danish nationwide register-based cohort study extracted 18-60-year-old individuals between 2003-2007 with concussion from the Danish National Patient Register (ICD-10 S06.0). Controls were matched on age, sex, and municipality. Patients and controls were followed for 5 years starting three months after injury. Exclusion criteria were neurological injuries and unavailability to the labour market in the inclusion period (2003-2007) and 5-years before injury (1998-2002). Labour market states were defined from transfer income data in the Danish Register for Evaluation of Marginalization. Incidence rates of transitions between these labour market states were analysed in multistate models. Transitions were bundled in favourable and adverse transitions between labour market states and the difference in incidence rates between individuals with concussion relative to matched controls were assessed with hazard ratios from Cox regression models.

RESULTS

Persons with concussion (n = 15.580) had a lower incidence of favourable transitions (HR 0.88, CI 0.86-0.90) and a higher incidence of adverse transitions (HR 1.30, CI 1.27-1.35), relative to matched controls (n = 16.377). The effect of concussion differed depending on health and socioeconomic characteristics. Notably, individuals between 30-39 years (HR 0.83, CI 0.79-0.87), individuals with high-income (200.000-300.000 DKK) (HR 0.83, CI 0.80-0.87), and wage earners with management experience (HR 0.60, CI 0.44-0.81) had a markedly lower incidence of favourable transitions compared to controls. Additionally, individuals with high income also had a higher incidence of adverse transitions (HR 1.46, CI 1.34-1.58) compared to controls.

CONCLUSIONS

Concussion was associated with enhanced risk of adverse transitions between labour market states and lower occurrence of favourable transitions, indicating work disability, potentially due to persistent post-concussive symptoms. Some age groups, individuals with high income, and employees with management experience may be more affected.

A comprehensive characterization of cognitive performance, clinical symptoms, and cortical activity following mild traumatic brain injury (mTBI)

OBJECTIVE

The objective of this study was to investigate clinical symptoms, cognitive performance and cortical activity following mild traumatic brain injury (mTBI).

METHODS

We recruited 30 individuals in the sub-acute phase post mTBI and 28 healthy controls with no history of head injury and compared these groups on clinical, cognitive and cortical activity measures. Measures of cortical activity included; resting state electroencephalography (EEG), task related EEG and combined transcranial magnetic stimulation with electroencephalography (TMS-EEG). Primary analyses investigated clinical, cognitive and cortical activity differences between groups. Exploratory analyses investigated the relationships between these measures.

RESULTS

At 4 weeks' post injury, mTBI participants exhibited significantly greater post concussive and clinical symptoms compared to controls; as well as reduced cognitive performance on verbal learning and working memory measures. mTBI participants demonstrated alterations in cortical activity while at rest and in response to stimulation with TMS.

CONCLUSIONS

The present study comprehensively characterized the multidimensional effect of mTBI in the sub-acute phase post injury, showing a broad range of differences compared to non-mTBI participants. Further research is needed to explore the relationship between these pathophysiologies and clinical/cognitive symptoms in mTBI.

A vocational intervention that enhances return to work after severe acquired brain injury: A pragmatic trial

BACKGROUND

Following a severe acquired brain injury, individuals often have low return to work rates. The Vocational Intervention Program (VIP), a partnership of Brain Injury Rehabilitation Program community rehabilitation centres with external vocational rehabilitation providers in New South Wales, Australia, was developed to facilitate a return to competitive employment for working-age people.

OBJECTIVES

To evaluate the efficacy of the VIP partnership model, this intervention was compared to outcomes from a health-based brain injury vocational rehabilitation centre (H-VR) or community brain injury rehabilitation centres ("treatment as usual"; TAU).

METHODS

A 3-arm non-randomized controlled trial was conducted among the 12 adult rehabilitation centres of the NSW Brain Injury Rehabilitation Program. The VIP arm was delivered by 6 community rehabilitation centres in partnership with 3 external private Vocational Rehabilitation providers. The H-VR arm was delivered by 1 health-based vocational rehabilitation centre and the 5 remaining centres delivered TAU. Competitive employment status ("Yes"/"No") and clinician ratings of disability and participation were collected pre- and post-intervention, and at 3-month follow-up. Multilevel models were conducted to investigate change over time by treatment arm.

RESULTS

In total, 148 individuals with severe brain injury were included in the trial: n = 75 (VIP), n = 33 (H-VR) and n = 40 (TAU). Sixty-five people (of 108, 60%) completed the VR intervention. A significant arm-by-time interaction was found, with higher return to work rates from pre- to post-intervention in VIP and H-VR arms compared to TAU (P = 0.0002). Significant arm-by-time interactions also indicated improved work-related participation and independent living skills from pre- to post-intervention in VIP and H-VR compared to the TAU arm (P < 0.05). These improvements were maintained at 3-month follow-up.

CONCLUSIONS

The VIP improved return to competitive employment at comparable rates to the specialist H-VR. Larger-scale adoption of the VIP model could provide significant improvements in vocational rehabilition sevices to support people in their return to work following severe brain injury.

VR for Vocational and Ecological Rehabilitation of Patients With Cognitive Impairment: A Survey

Cognitive impairment arises from various brain injuries or diseases, such as traumatic brain injury, stroke, schizophrenia, or cancer-related cognitive impairment. Cognitive impairment can be an obstacle for patients to the return-to-work. Research suggests various interventions using technology for cognitive and vocational rehabilitation. The present work offers an overview of sixteen vocational or ecological VR-based clinical studies among patients with cognitive impairment. The objective is to analyze these studies from a VR perspective focusing on the VR apparatus and tasks, adaptivity, transferability, and immersion of the interventions. Our results highlight how a higher level of immersion could bring the participants to a deeper level of engagement and transferability, rarely assessed in current literature, and a lack of adaptivity in studies involving patients with cognitive impairments. From these considerations, we discuss the challenges of creating a standardized yet adaptive protocol and the perspectives of using immersive technologies to allow precise monitoring, personalized rehabilitation and increased commitment.

Fluid biomarkers and neuroimaging in mild traumatic brain injury: current uses and potential future directions for clinical use in emergency medicine

Mild traumatic brain injury is a common presentation to the emergency department, with current management often focusing on determining whether a patient requires a CT head scan and/or neurosurgical intervention. There is a growing appreciation that approximately 20%-40% of patients, including those with a negative (normal) CT, will develop ongoing symptoms for months to years, often termed post-concussion syndrome. Owing to the requirement for improved diagnostic and prognostic mechanisms, there has been increasing evidence concerning the utility of both imaging and blood biomarkers.Blood biomarkers offer the potential to better risk stratify patients for requirement of neuroimaging than current clinical decisions rules. However, improved assessment of the clinical utility is required prior to wide adoption. MRI, using clinical sequences and advanced quantitative methods, can detect lesions not visible on CT in up to 30% of patients that may explain, at least in part, some of the ongoing problems. The ability of an acute biomarker (be it imaging, blood or other) to highlight those patients at greater risk of ongoing deficits would allow for greater personalisation of follow-up care and resource allocation.We discuss here both the current evidence and the future potential clinical usage of blood biomarkers and advanced MRI to improve diagnostic pathways and outcome prediction following mild traumatic brain injury.

Exploring the Association between Personality Traits, Symptom Burden, and Return to Work after Mild-to-Moderate Traumatic Brain Injury

Approximately 30% of individuals with mild traumatic brain injury (mTBI) experience persistent post-concussion symptoms (PPCS). Personality factors have been linked to PPCS, yet, the association between personality traits and outcomes after mTBI is poorly understood. The aim of this study was to evaluate the association between personality traits, PPCS, and return to work (RTW) in patients with mild-to-moderate traumatic brain injury (TBI). Data from eighty-seven participants with mild-to-moderate TBI were analyzed. Sociodemographic, injury, and work characteristics and depressive symptoms were recorded 2-3 months post-injury. Personality traits were measured using the NEO Five-Factor Inventory-3. PPCS and RTW were assessed 15 months post-injury. Multiple linear regression models were performed. The factors associated with more severe PPCS were female sex, higher levels of neuroticism, openness to experience and conscientiousness, extra-cranial injuries, and depressive symptoms. The factors associated with lower RTW were female sex, higher levels of neuroticism, and conscientiousness. However, after controlling for PPCS, personality traits were no longer significantly associated with RTW. In conclusion, specific personality traits were associated with more severe PPCS and may be indirectly associated with RTW via PPCS. Hence, personality traits may be important to assess to identify patients at risk of less favorable outcomes after mild-to-moderate TBI.

Fear avoidance and return to work after mild traumatic brain injury

OBJECTIVES

Fear avoidance is associated with symptom persistence after mild traumatic brain injury (mTBI). In this study, we investigated whether fear avoidance was associated with other outcomes such as return to work-related activity (RTW).

MATERIALS AND METHODS

We analyzed associations between fear avoidance and RTW 6-9 months after mTBI, in two merged prospective mTBI cohorts. Adult participants aged 16 or over (n=175), presenting to outpatient services in New Zealand within 3 months of their injury, who were engaged in work-related activity at the time of injury, were included. Participants completed the Fear Avoidance Behavior after Traumatic Brain Injury (FAB-TBI) questionnaire at enrollment and 6 months later. Associations between FAB-TBI scores and RTW outcome were analyzed using multivariate approaches.

RESULTS

Overall, 53% of participants had RTW by 6-9 months after mTBI. While early fear avoidance was weakly associated with RTW, persistent high fear avoidance between study assessments or increasing avoidance with time were associated with greater odds of still being off work 6-9 months after injury.

CONCLUSIONS

Pervasive and increasing avoidance of symptom triggers after mTBI were associated with lower rates of RTW 6-9 months after mTBI. Further research is needed to better understand transition points along the recovery trajectory where fear avoidance behaviors fade or increase after mTBI.

Post-Concussion Symptoms and Disability in Adults with Mild Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Studies investigating long-term symptoms and disability after mild traumatic brain injury (mTBI) have yielded mixed results. This systematic review and meta-analysis aimed to determine the prevalence of self-reported post-concussion symptoms (PCS) and disability following mTBI. We systematically searched MEDLINE, Embase, CINAHL, CENTRAL, and PsycInfo to identify inception cohort studies of adults with mTBI. Paired reviewers independently extracted data and assessed risk of bias with the Scottish Intercollegiate Guidelines Network criteria. We identified 43 eligible studies for the systematic review; 41 were rated as high risk of bias, primarily due to high attrition (> 20%). Twenty-one studies (49%) were included in the meta-analyses (five studies were narratively synthesized; 17 studies were duplicate reports). At 3-6 months post-injury, the estimated prevalence of PCS from random-effects meta-analyses was 31.3% (95% confidence interval [CI] = 25.4-38.4) using a lenient definition of PCS (2-4 mild severity PCS) and 18.3% (95% CI = 13.6-24.0) using a more stringent definition. The estimated prevalence of disability was 54.0% (95% CI = 49.4-58.6) and 29.6% (95% CI = 27.8-31.5) when defined as Glasgow Outcome Scale-Extended <8 and <7, respectively. The prevalence of symptoms similar to PCS was higher in adults with mTBI versus orthopedic injury (prevalence ratio = 1.57, 95% CI = 1.22-2.02). In a meta-regression, attrition rate was the only study-related factor significantly associated with higher estimated prevalence of PCS. Setting attrition to 0%, the estimated prevalence of PCS (lenient definition) was 16.1%. We conclude that nearly one in three adults who present to an emergency department or trauma center with mTBI report at least mild severity PCS 3-6 months later, but controlling for attrition bias, the true prevalence may be one in six. Studies with representative samples and high retention rates are needed.

Usability evaluation of a self-management mobile application for individuals with a mild traumatic brain injury

Objective

Mild traumatic brain injuries (mTBIs) are common and may result in persisting symptoms. Mobile health (mHealth) applications enhance treatment access and rehabilitation. However, there is limited evidence to support mHealth applications for individuals with an mTBI. The primary purpose of this study was to evaluate user experiences and perceptions of the Parkwood Pacing and Planning™ application, an mHealth application developed to help individuals manage their symptoms following an mTBI. The secondary purpose of this study was to identify strategies to improve the application. This study was conducted as part of the development process for this application.

Methods

A mixed methods co-design encompassing an interactive focus group and a follow-up survey was conducted with patient and clinician-participants (n = 8, four per group). Each group participated in a focus group consisting of an interactive scenario-based review of the application. Additionally, participants completed the Internet Evaluation and Utility Questionnaire (UQ). Qualitative analysis on the interactive focus group recordings and notes was performed using phenomenological reflection through thematic analyses. Quantitative analysis included descriptive statistics of demographic information and UQ responses.

Results

On average, clinician and patient-participants positively rated the application on the UQ (4.0 ± .3, 3.8 ± .2, respectively). User experiences and recommendations for improving the application were categorized into four themes: simplicity, adaptability, conciseness, and familiarity.

Conclusion

Preliminary analyses indicates patients and clinicians have a positive experience when using the Parkwood Pacing and Planning™ application. However, modifications that improve simplicity, adaptability, conciseness, and familiarity may further improve the user's experience.

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.

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.

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.

Impact of Timing of Mental Health Interventions for Mild Traumatic Brain Injury Patients: A 10-year Matched Cohort Study of Workers' Compensation Claims

OBJECTIVE

To examine the impact of timing of mental health interventions in workers' compensation claims for mild traumatic brain injury (MTBI).

METHODS

A 10-year matched retrospective cohort study of MTBI claims. Cases who started treatment within 3 months of the date of injury were hard matched to cases who started treatment more than 3 months after the date of injury. Outcomes were incremental cost difference and loss of earnings benefit duration 1 year after first intervention.

RESULTS

Seventeen percent (17%) of patients received mental health interventions. The early mental health intervention group had lower mean costs (incremental difference$1580 [95% CI: $5718 to $2085]) and shorter durations of disability (off loss of earnings) (59.2% versus 46.6%, NS). Sensitivity and stratified analyses demonstrated the same trend.

CONCLUSIONS

Early mental health interventions for MTBI patients may lead to reduced health care costs and shorter durations of disability.

Return to work after mild traumatic brain injury: association with positive CT and MRI findings

Background

Return to work (RTW) might be delayed in patients with complicated mild traumatic brain injury (MTBI), i.e., MTBI patients with associated traumatic intracranial lesions. However, the effect of different types of lesions on RTW has not studied before. We investigated whether traumatic intracranial lesions detected by CT and MRI are associated with return to work and post-concussion symptoms in patients with MTBI.

Methods

We prospectively followed up 113 adult patients with MTBI that underwent a brain MRI within 3–17 days after injury. Return to work was assessed with one-day accuracy up to one year after injury. Rivermead Post-Concussion Symptoms Questionnaire (RPQ) and Glasgow Outcome Scale Extended (GOS-E) were conducted one month after injury. A Kaplan–Meier log-rank analysis was performed to analyze the differences in RTW.

Results

Full RTW-% one year after injury was 98%. There were 38 patients with complicated MTBI, who had delayed median RTW compared to uncomplicated MTBI group (17 vs. 6 days), and more post-concussion symptoms (median RPQ 12.0 vs. 6.5). Further, RTW was more delayed in patients with multiple types of traumatic intracranial lesions visible in MRI (31 days, n = 19) and when lesions were detected in the primary CT (31 days, n = 24). There were no significant differences in GOS-E.

Conclusions

The imaging results that were most clearly associated with delayed RTW were positive primary CT and multiple types of lesions in MRI. RTW-% of patients with MTBI was excellent and a single intracranial lesion does not seem to be a predictive factor of disability to work.

Measuring socioeconomic outcomes in trauma patients up to one year post-discharge: A systematic review and meta-analysis

INTRODUCTION

Trauma accounts for nearly one-tenth of the global disability-adjusted life-years, a large proportion of which is seen in low- and middle-income countries (LMICs). Trauma can affect employment opportunities, reduce social participation, be influenced by social support, and significantly reduce the quality of life (QOL) among survivors. Research typically focuses on specific trauma sub-groups. This dispersed knowledge results in limited understanding of these outcomes in trauma patients as a whole across different populations and settings. We aimed to assess and provide a systematic overview of current knowledge about return-to-work (RTW), participation, social support, and QOL in trauma patients up to one year after discharge.

METHODS

We undertook a systematic review of the literature published since 2010 on RTW, participation, social support, and QOL in adult trauma populations, up to one year from discharge, utilizing the most commonly used measurement tools from three databases: MEDLINE, EMBASE, and the Cochrane Library. We performed a meta-analysis based on the type of outcome, tool for measurement, and the specific effect measure as well as assessed the methodological quality of the included studies.

RESULTS

A total of 43 articles were included. More than one-third (36%) of patients had not returned to work even a year after discharge. Those who did return to work took more than 3 months to do so. Trauma patients reported receiving moderate social support. There were no studies reporting social participation among trauma patients using the inclusion criteria. The QOL scores of the trauma patients did not reach the population norms or pre-injury levels even a year after discharge. Older adults and females tended to have poorer outcomes. Elderly individuals and females were under-represented in the studies. More than three-quarters of the included studies were from high-income countries (HICs) and had higher methodological quality.

CONCLUSION

RTW and QOL are affected by trauma even a year after discharge and the social support received was moderate, especially among elderly and female patients. Future studies should move towards building more high-quality evidence from LMICs on long-term socioeconomic outcomes including social support, participation and unpaid work.

Traumatic Microbleeds in Mild Traumatic Brain Injury Are Not Associated with Delayed Return to Work or Persisting Post-Concussion Symptoms

The main objective of this prospective cohort study was to evaluate whether traumatic microbleeds (TMBs) are a significant prognostic factor of return to work (RTW), post-traumatic symptoms, and overall recovery in patients with mild traumatic brain injury (mTBI). One hundred and thirteen patients with mTBI were recruited from the Helsinki University Hospital emergency units. All patients underwent multi-contrast 3T magnetic resonance imaging (MRI) 3-17 days after mTBI. Patients were evaluated in the Traumatic Brain Injury Outpatient Clinic of Helsinki University Hospital 1 month after injury. Post-concussion symptoms were assessed with the Post-Concussion Symptom Questionnaire (RPQ) and overall recovery was assessed with the Glasgow Outcome Scale Extended (GOS-E). Their time to RTW was continuously measured up to 1 year after TBI. Median RTW was 9 days (interquartile range [IQR] 4-30) after mTBI and full RTW rate after 1 year was 98%. Patients with TMBs (n = 22) did not have more post-concussion symptoms (median RPQ 10.0 vs. 7.0, p = 0.217) or worse overall recovery (58% vs. 56% with GOS-E = 8, p = 0.853) than patients without TMBs (n = 91). There was no significant difference in time to RTW (13.5 vs. 7.0 days, p = 0.063). In this study, patients with TMBs did not have delayed RTW or more post-concussion symptoms than other patients with mTBI. TMBs in mTBI do not seem to be a significant prognostic factor of RTW.

Measuring post-discharge socioeconomic and quality of life outcomes in trauma patients: a scoping review

PURPOSE

Trauma is a global public health challenge. Measuring post-discharge socioeconomic and quality-of-life outcomes can help better understand and reduce the consequences of trauma.

METHODS

We performed a scoping review to map the existing research on post-discharge outcomes for trauma patients, irrespective of the country or setting in which the study was performed. The scoping review was conducted by searching six databases - MEDLINE, EMBASE, the Cochrane Library, Global Index Medicus, BASE, and Web of Science - to identify all articles that report post-discharge socioeconomic or quality of life outcomes in trauma patients from 2009 to 2018.

RESULTS

Seven hundred fifty-eight articles were included in this study, extracting 958 outcomes. Most studies (82%) were from high-income countries (HICs). More studies from low- and middle-income countries (LMICs) were cross-sectional (71%) compared with HIC settings (46%). There was a wide variety of different definitions, interpretations, and measurements used by various articles for similar outcomes. Quality of life, return to work, social support, cost, and participation were the main outcomes studied in post-discharge trauma patients.

CONCLUSIONS

The wide range of outcomes and outcome measures reported across different types of injuries and settings. This variability can be a barrier when comparing across different types of injuries and settings. Post-discharge trauma studies should move towards building evidence based on standardized measurement of outcomes.

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. .

Cognitive performance in older adults at three months following mild traumatic brain injury

Introduction: In the context of limited research assessing outcomes following mild traumatic brain injury (mTBI) in older adults, this study evaluated cognitive outcomes through prospective memory, and expected that performance of an older mTBI group (≥65 years) would be lower compared to orthopedic and community controls. The study also explored whether cognitive resources (retrospective memory, executive function) moderated any association between presenting Glasgow Coma Scale (GCS) and prospective memory.Method: At three-months post-injury, a mTBI group (n = 39), an orthopedic control group (n = 63), and a community control group (n = 46) completed a neuropsychological assessment, including (i) prospective memory, using a standardized paper-and-pencil task (Cambridge Prospective Memory Test), an augmented reality task and a naturalistic task, and (ii) standardized measures of retrospective memory (Hopkins Verbal Learning Test) and executive function (Trail Making Test). Group performances were compared, and bootstrapped moderation analyses evaluated the role of cognitive resources in the relationship between GCS and prospective memory outcome.Results: The mTBI group, as compared to community controls, performed significantly lower on the augmented reality task (d = -0.64 to d = -0.79), and there was a small-moderate but non-significant effect (d = -0.45) on the naturalistic task. There were no differences between the mTBI group and orthopedic controls. Retrospective memory was a unique predictor of the augmented reality task (B = 1.83) and moderated the relationship between presenting GCS and the naturalistic task (B = -5.60). Executive function moderated the association between presenting GCS and augmented reality (B = -1.13) and naturalistic task (B = -1.57).Conclusions: At three-months post-mTBI, older adults are at risk of poor cognitive performance; and the relationship between GCS and prospective memory can be moderated by cognitive resources. Further follow-up is indicated to determine whether impairments resolve or persist over time.

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.

Patient Perspectives on Key Outcomes for Vocational Rehabilitation Interventions Following Traumatic Injury

Returning to work after traumatic injury can have a range of benefits, but there is currently little research that incorporates patient perspectives to identify outcomes of vocational rehabilitation interventions that are important to survivors. Trauma survivors (n = 17) participated in in-depth semi-structured interviews or focus groups exploring outcomes that were important to them for recovery and return to work. Data were analysed using thematic analysis. Participants identified a range of outcomes that they considered important and necessary to facilitate a successful and sustainable return to work: physical and psychological recovery, purposeful life engagement, managing expectations of recovery, managing expectations about return to work, and employers’ expectations. Our participants advocated for a multifaceted and biopsychosocial understanding of recovery and outcomes that need to be captured for vocational rehabilitation interventions. Implications for practice and research are discussed, and recommendations are given based on the findings.

Predictors of six-month inability to return to work in previously employed subjects after mild traumatic brain injury: A TRACK-TBI pilot study

INTRODUCTION

Return to work (RTW) is an important milestone of mild traumatic brain injury (mTBI) recovery. The objective of this study was to evaluate whether baseline clinical variables, three-month RTW, and three-month postconcussional symptoms (PCS) were associated with six-month RTW after mTBI.

METHODS

Adult subjects from the prospective multicenter Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot study with mTBI (Glasgow Coma Scale 13-15) who were employed at baseline, with completed three-and six-month RTW status, and three-month Acute Concussion Evaluation (ACE), were extracted. Univariate and multivariable analyses were performed for six-month RTW, with focus on baseline employment, three-month RTW, and three-month ACE domains (physical, cognitive, sleep, and/or emotional postconcussional symptoms (PCS)). Odds ratios (OR) and 95% confidence intervals [CI] were reported. Significance was assessed at p < 0.05.

RESULTS

In 152 patients aged 40.7 ± 15.0years, 72% were employed full-time at baseline. Three- and six-month RTW were 77.6% and 78.9%, respectively. At three months, 59.2%, 47.4%, 46.1% and 31.6% scored positive for ACE physical, cognitive, sleep, and emotional PCS domains, respectively. Three-month RTW predicted six-month RTW (OR = 19.80, 95% CI [7.61-51.52]). On univariate analysis, scoring positive in any three-month ACE domain predicted inability for six-month RTW (OR = 0.10-0.11). On multivariable analysis, emotional symptoms predicted inability to six-month RTW (OR = 0.19 [0.04-0.85]). Subjects who scored positive in all four ACE domains were more likely to be unable to RTW at six months (4 domains: 58.3%, vs. 0-to-3 domains: 9.5%; multivariable OR = 0.09 [0.02-0.33]).

CONCLUSIONS

Three-month post-injury is an important time point at which RTW status and PCS should be assessed, as both are prognostic markers for six-month RTW. Clinicians should be particularly vigilant of patients who present with emotional symptoms, and patients with symptoms across multiple PCS categories, as these patients are at further risk of inability to RTW and may benefit from targeted evaluation and support.

Prognosis after Mild Traumatic Brain Injury: Influence of Psychiatric Disorders

BACKGROUND

We evaluated the prevalence of psychiatric disorders in mild traumatic brain injury (MTBI) patients and investigated psychiatric comorbidity in relation to subjective symptoms and return to work (RTW).

METHODS

We recruited 103 MTBI patients (mean age 40.8 years, SD 3.1) prospectively from University Hospital. The patients were followed up for one year. The Rivermead Post-Concussion Symptom Questionnaire (RPQ) and Extended Glasgow Outcome Scale (GOSE) were administered one month after MTBI. Three months after MTBI, any psychiatric disorders were assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders.

RESULTS

Psychiatric disorders were diagnosed in 26 patients (25.2%). The most common disorders were previous/current depression. At three months, there was no difference between patients with psychiatric disorders versus those without them in RTW (95.7% vs. 87.3%, p = 0.260) or at least in part-time work (100% vs. 94.4%, p = 0.245). In Kaplan-Meier analysis, the median time to RTW was 10 days for both groups. The median RPQ score was 13.0 (Interquartile range (IQR) 6.5-19.0) in patients with a psychiatric disorder compared to 8.5 (IQR 2.3-14.0) in those without one (p = 0.021); respectively, the median GOSE was 7.0 (IQR 7.0-8.0) compared to 8.0 (IQR 7.0-8.0, p = 0.003).

CONCLUSIONS

Approximately every fourth patient with MTBI had a psychiatric disorder. These patients reported more symptoms, and their functional outcome measured with GOSE at one month after MTBI was worse. However, presence of any psychiatric disorder did not affect RTW. Early contact and adequate follow-up are important when supporting the patient's return to work.

Factors associated with employment outcome after critical illness: Systematic review, meta-analysis, and meta-regression

AIMS

To synthesize data on prevalence and risk factors for return to work (RTW) in ICU survivors.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PUBMED, CINAHL, EMBASE and PsycINFO databases were searched from 2000-Feb 2020.

REVIEW METHODS

Peer-reviewed articles that included adult ICU survivors and employment outcomes. Two investigators independently reviewed articles following the PRISMA protocol. Pooled prevalence for RTW was calculated. Meta-regression analyses were performed to assess the association between disability policies, temporal factors and RTW following ICU.

RESULTS

Twenty-eight studies (N = 8,168) met the inclusion criteria. All studies were scored as 'low risk of bias'. Using meta-analysis, the proportion (95% CI) of RTW following ICU was 29% (0.20,0.42), 59% (0.50,0.70), 56% (0.50,0.62), 63% (0.54,0.72), 58% (0.37,0.91), 58% (0.42,0.81), and 44% (0.25,0.76) at 3, 4-6, 7-12, 13-24, 25-36, 37-48, and 49-60 months, respectively. Time and disability policy support are factors associated with the proportion of ICU survivors who RTW. Through meta-regression, there is a 20% increase (95% CI: 0.06, 0.33) in the proportion of individuals who RTW per year. However, the average rate of increase slows by 4% (-0.07, -0.1) per year. In countries with high support policies, the proportion of RTW is 32% higher compared with countries with low support policies (0.08, 0.24). However, as subsequent years pass, the additional proportion of individuals RTW in high support countries declines (β = -0.06, CI: -0.1, -0.02).

CONCLUSIONS

Unemployment is common in ICU survivors. Countries with policies that give higher support for disabled workers have a higher RTW proportion to 3 years following ICU admission. However, from 3-5 years, there is a shift to countries with lower support policies having better employment outcomes.

IMPACT

Health care policies have an impact on RTW rate in survivors of ICU. Healthcare providers, including nurses, can function as public advocates to facilitate policy change.

Facilitators of and barriers to return to work after mild traumatic brain injury: A thematic analysis

Individuals with mild traumatic brain injury (mTBI) may experience protracted symptoms affecting their ability to work. Several actors may facilitate or act as a barrier to a successful return to work (RTW). This qualitative study used semi-structured in-depth interviews with 22 adults with mTBI at 2-5 years post injury, targeting experiences of how different actors facilitated or acted as a barrier in the RTW process, and encompassed the mTBI trajectory from the acute phase to the post-acute phase. A thematic analysis with a hermeneutical phenomenological approach was used to analyse data. Three main themes emerged. (1) Worker-employer relationship: Workplace accommodations such as decreased working hours, modified working conditions, and support from co-workers were lacking. (2) The role of the general practitioner: The general practitioner was lacking treatment and referral opportunities and failed to provide the patient with relevant and individualized guidance. (3) Municipal case management: Participants perceived being met with distrust by social workers, follow-up assessments were too frequent, unnecessary, and did not target concussion, and rehabilitation was referred too late. Clinical practice guidelines to improve referral to relevant concussion rehabilitation in case of persistent symptoms are needed to inform clinicians, employers, and public institutions to facilitate a successful RTW.

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.

State-Federal Vocational Rehabilitation in Traumatic Brain Injury: What Predictors Are Associated With Employment Outcomes?

This study identified predictors of employment for individuals with traumatic brain injury (TBI). Data from 4,923 individuals with TBI were extracted from the Rehabilitation Services Administration’s Case Service Report (RSA-911) database. A multiple logistic regression model using demographics, disability-related variables, vocational rehabilitation (VR) service variables, and their interactions correctly classified 69.5% of the cases as successfully employed or not successfully employed. The model explained approximately 27.1% of the variance in employment outcomes. Results indicated that level of education, race/ethnicity, age at application, preemployment status, Supplemental Security Income (SSI), Social Security Disability Insurance (SSDI), comorbid depression, and case expenditure were significantly associated with employment outcomes (all p ≤ .05). VR variables that showed the most significant positive effect on employment outcomes were on-the-job support, job placement, and on-the-job training. Race/ethnicity moderated the effect of college training, supported employment, transportation, and extended evaluation or work trial assessment services on employment outcomes. The findings have implications for promoting the use of those VR services that are strongly related to employment outcomes for persons with TBI. They also point to the need for rehabilitation personnel to address some of the demographic and disability-related barriers to successful employment.
