Biographical disruption, adjustment and reconstruction of everyday occupations and work participation after mild traumatic brain injury. A focus group study

'A new sense of my former self' - transforming the self through vocational rehabilitation for people with acquired brain injury

BACKGROUND

Acquired Brain injury (ABI) causes ripples throughout the occupational and social fabric. It enters people's lives at a significant personal cost, encroaching on people's sense of self. Vocational rehabilitation is a viable venue to regain control of their life and support them in forming a new sense of self. From an occupational perspective, little is known about how vocational rehabilitation can support people through transforming their sense of self.

AIM

This study aims to explore how vocational rehabilitation may influence the relationship between sense of self and occupational engagement for persons with ABI. Material and Methods: Six persons with ABI were purposely sampled. Data were collected using semi-structured individual interviews and analysed using a hermeneutic approach.

RESULTS

The analysis resulted in three themes: a new sense of my former self, engaging in occupations as transformation, and the significance of support.

CONCLUSIONS

Participating in vocational rehabilitation can enable persons with ABI to form a new sense of self. Engaging in occupations and professional support is significant in the transformation process.

SIGNIFICANCE

From an occupational perspective, the knowledge gained in this study stresses the essential role occupational engagement and proper targeted support have for people struggling to return to work after ABI.

Use of Social Media Data Mining to Examine Needs, Concerns, and Experiences of People With Traumatic Brain Injury

PURPOSE

Given the limited availability of topic-specific resources, many people turn to anonymous social media platforms such as Reddit to seek information and connect to others with similar experiences and needs. Mining of such data can therefore identify unmet needs within the community and allow speech-language pathologists to incorporate clients' real-life insights into clinical practices.

METHOD

A mixed-method analysis was performed on 3,648 traumatic brain injury (TBI) subreddit posts created between 2013 and 2021. Sentiment analysis was used to determine the sentiment expressed in each post; topic modeling and qualitative content analysis were used to uncover the main topics discussed across posts. Subgroup analyses were conducted based on injury severity, chronicity, and whether the post was authored by a person with TBI or a close other.

RESULTS

There was no significant difference between the number of posts with positive sentiment and the number of posts with negative sentiment. Comparisons between subgroups showed significantly higher positive sentiment in posts by or about people with moderate-to-severe TBI (compared to mild TBI) and who were more than 1 month postinjury (compared to less than 1 month). Posts by close others had significantly higher positive sentiment than posts by people with TBI. Topic modeling identified three meta-themes: Recovery, Symptoms, and Medical Care. Qualitative content analysis further revealed that returning to productivity and life as well as sharing recovery tips were the primary focus under the Recovery theme. Symptom-related posts often discussed symptom management and validation of experiences. The Medical Care theme encompassed concerns regarding diagnosis, medication, and treatment.

CONCLUSIONS

Concerns and needs shift over time following TBI, and they extend beyond health and functioning to participation in meaningful daily activities. The findings can inform the development of tailored educational resources and rehabilitative approaches, facilitating recovery and community building for individuals with TBI.

In-depth assessment of quality of life and real life impact of mild traumatic brain injury in elderly by means of a focus group study

Traumatic Brain Injury (TBI) in the elderly population leads to more severe consequences than in young patients. However, the impact that TBI has on elderly patients' Quality of Life (QoL) has not been thoroughly investigated and is still unclear. Therefore, the main objective of this study is to qualitatively investigate changes in QoL after mild TBI in elderly patients. A focus group interview was conducted with 6 mild TBI patients, with a median age of 74 years old, admitted to the University Hospitals Leuven (UZ Leuven) between 2016 and 2022. The data analysis was performed following the guide provided by Dierckx de Casterlé et al. in 2012, using Nvivo software. Three themes emerged from the analysis: functional disturbances and symptoms, daily life after TBI, and life quality, feelings and satisfaction. The most reported factors that deteriorated QoL 1-5 years post-TBI in our cohort were the lack of support from partners and families, changes in self-perception and social life, tiredness, balance disturbances, headache, cognitive deterioration, changes in physical health, senses' disturbances, changes in sexual life, sleep problems, speech disturbances and dependence for daily life activities. No symptoms of depression or feelings of shame were reported. The acceptance of the situation and hope for improvement were shown to be the most important coping mechanisms for these patients. In conclusion, mild TBI in elderly patients frequently leads to changes in self-perception, daily life activities and social life 1-5 years after the injury, which could contribute to a loss of independence and QoL deterioration. The acceptance of the situation and a good support network seem to be protective factors for these patients' well-being after TBI.

The Impact of a Recent Concussion on College-Aged Individuals with Co-Occurring Anxiety: A Qualitative Investigation

College-aged individuals with anxiety are vulnerable to developing persistent concussion symptoms, yet evidence-based treatments for this population are limited. Understanding these individuals' perspectives is critical for developing effective interventions. We conducted qualitative interviews with 17 college-aged individuals (18-24 years old) with a recent (≤10 weeks) concussion and at least mild anxiety (≥5 on the GAD-7 questionnaire) to understand the life impact of their concussion. We identified 5 themes: (1) disruption to daily activities (e.g., reduced participation in hobbies and physical activity); (2) disruption to relationships (e.g., reduced social engagement, feeling dismissed by others, stigma, and interpersonal friction); (3) disruptions in school/work (e.g., challenges participating due to light sensitivity, cognitive or sleep disturbance, and related emotional distress); (4) changes in view of the self (e.g., feeling "unlike oneself", duller, or more irritable), and (5) finding "silver linings" after the injury (e.g., increased motivation). Concussions impact the lives of college-aged individuals with co-occurring anxiety in a broad range of domains, many of which remain largely neglected in standard concussion clinical assessment and treatment. Assessing and addressing these issues has the potential to limit the negative impact of concussion, promote recovery, and potentially help prevent persistent concussion symptoms in this at-risk population.

Indicators of life success from the perspective of individuals with traumatic brain injury: a scoping review

PURPOSE

The purpose was to synthesize qualitative literature and identify indicators of life success (positive life outcomes and experiences) that can help in understanding resiliency in the context of traumatic brain injury (TBI).

METHODS

This scoping review involved searching nine online databases for population (TBI) and context (qualitative literature). Searches retrieved 42 852 articles and, after two-stage screening, 76 articles met the inclusion criteria of reporting indicators of life success from the perspective of individuals with TBI.

RESULTS

Most studies were conducted in North America, Australia, or Europe. Participants were people living with TBI (mild to severe), of all age ranges. Positive life experiences were organized within four domains: understanding of oneself and one's life, social relationships and interaction, doing (engagement in activities, sense of control and accomplishment), and hope for the future.

CONCLUSIONS

The positive life experiences reflect both processes and outcomes (indicators of success) and highlight the need for a multidimensional approach when seeking to understand resiliency following TBI. The transactional framework of life experiences can be applied in future TBI resiliency research to understand how individuals negotiate adversity through experiences promoting understanding of oneself and the world, social relationships, engagement in activity and hope. Implications for rehabilitationRehabilitation services should consider how to afford opportunities for engagement in activity, social interaction, meaning making (i.e., coming to new understandings), and hope.With respect to engaging in activity and social relationships, having social interaction, being understood, being active and productive, having autonomy, and having accomplishments, reflect important experiences to enable within rehabilitation services.Rehabilitation professionals should consider how providing opportunities for their clients to have positive life experiences may contribute toward an adaptive and empowered mindset.

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.

Experiences of Children and Youth With Concussion: A Qualitative Study

IMPORTANCE

Concussions are common among children and youth. To date, the pediatric concussion literature has focused on quantitative reports of the effects of concussion and return-to-activity guidelines. However, the subjective experiences of children and youth returning to occupations postconcussion have largely been ignored. An understanding of these experiences is critical to inform effective concussion management.

OBJECTIVE

To investigate the experiences of children and youth returning to occupations after sustaining a concussion and the impacts on their future engagement in occupation.

DESIGN

Qualitative interpretive description was used for data analysis and interpretation.

SETTING

Community.

PARTICIPANTS

Children and youth ages 11 to 18 yr from a cohort study were recruited to be interviewed about their experiences of engaging in occupations postconcussion.

OUTCOMES AND MEASURES

Interviews were conducted 3 to 24 mo postconcussion, transcribed verbatim, and analyzed using interpretive description to identify themes.

RESULTS

Eight children and youth (5 male, 3 female) were included. Analyses revealed three themes of the experiences of children and youth returning to occupations after concussion: diverse experiences of concussion, knowledge is key to concussion management, and concussions affect occupational engagement.

CONCLUSIONS AND RELEVANCE

This study highlights the importance of considering a person's needs to enable effective concussion treatment plans. The results suggest the need for an occupation-based framework to guide interventions in pediatric concussion management. What This Article Adds: Our findings indicate that children and youth report variable recovery patterns, a lack of knowledge about concussion recovery, and a negative effect of concussion on occupational engagement.

"Manoeuvring in uncharted waters - a balancing act": A qualitative exploration of treatment and improvement after mild traumatic brain injury

Background: Individuals who have sustained mild traumatic brain injury (mTBI) with a protracted course of recovery may experience long-lasting somatic, cognitive, and emotional symptoms affecting activities of daily living. There is limited knowledge regarding individuals' lived experiences with treatments and advice provided.Purpose: To explore how individuals with mTBI describe and make sense of their injury, recovery process, and their experiences with various treatment approaches.Methods: Eight participants with mTBI were recruited from the intervention group in an ongoing randomized controlled trial regarding return-to-work. They were interviewed once after treatment delivery using a qualitative hermeneutical approach. Thematic analysis was applied, and findings are discussed in light of a salutogenic theory.Results: Participants expressed uncertainty regarding conflicting advice they received in the early phase of recovery. Three main themes were developed: (1) "Ambiguity and hope"; (2) "Uncertainty concerning activity and rest"; and (3) "To become the person I used to be vs. to become a new version of myself."Conclusion: The findings showed that the participants experienced both uncertainty and hope for further recovery. The recovery process is challenged by the variability of TBI symptoms that affects participation in everyday life, as well as the conflicting advice received by the participants.

Experiences of inpatient rehabilitation from the perspective of persons with acquired brain injury

BACKGROUND

Perspectives of individuals with acquired brain injury (ABI) regarding inpatient rehabilitation experiences can inform patient-centered care; however, these voices are under-represented in the literature.

PURPOSE

To explore the experiences, needs, and preferences of patients from an ABI inpatient rehabilitation program in Ontario.

METHODS

Using an interpretive description approach, we interviewed 12 participants and analyzed the transcripts inductively to generate themes.

FINDINGS

We identified three major themes: (1) Life Rerouted - participants felt their lives diverted due to ABI, with rehabilitation seen as a way to return to pre-injury life, (2) Autonomy within Rehab highlighted the perceived importance of personal autonomy in decision-making within rehabilitation, and (3) Life (and Recovery) Go On reflected an ongoing recovery process after discharge - leading to mixed emotions. An overall message, "re-establishing personal identity is important to the recovery process," reflected theories of biographical disruption and relational autonomy.

IMPLICATIONS

Our findings provide a patient perspective for clinicians and administrators to consider. We found that ABI was significantly disruptive to personal identity - resulting in tensions in autonomy while attempting to reclaim a sense of identity. We suggest counseling services and strategies supporting post-injury adjustment, along with ways for rehabilitation professionals to enhance patient autonomy where possible.Implications for rehabilitationSustaining an ABI can significantly disrupt personal identity and sense of autonomy - especially as persons occupy the role of "patient" while in inpatient rehabilitation.Psychological support is recommended to address the impacts of ABI on patients' sense of identity, as well as on family members.Strategies of support might include, providing formal psychotherapy, as well as creating opportunities for patients and family members to discuss the changes they are experiencing, and to establish their personal narratives (e.g., through writing or art) or peer mentorship programs between discharged and current patients.Clinicians can enhance patient autonomy by increasing opportunities for communication with patients about choice; educating patients and family members on the rehabilitation team's decision-making process, and other methods that increase communication and provide consistent up-to-date information to patients and their family members.

Returning to work or working on one's rehabilitation: Social identities invoked by impaired workers and professionals in health care and employment services

For persons with a long-term illness or impairment, return-to-work decisions involve considerations about work capacity, opportunities in the labour market, the impact of injuries, further treatment requirements, physical and cognitive rehabilitation, and mental health recovery. These considerations are undertaken by the affected individuals as well as by professionals in health care and employment services. Drawing upon institutional theories of organisations, especially the understanding that institutional logics provide different social identities to injured individuals, we study rehabilitation processes following multi-trauma or traumatic brain injury (TBI) within the Scandinavian welfare model. We identify which social identities are activated in professionals' considerations and in the stories of the injured individuals. The aim is to understand how professionals' reasoning about the clients' problems influences return-to-work processes. Our primary finding is that the wageworker identity, invoked by the injured individuals themselves, is subordinated by the professionals to the logic of profession and the associated patient identity. Consequently, not only is impaired people's anti-discrimination right to reasonably adjusted work ignored, ignored is also a possible resource in the rehabilitation process. Additionally, individuals who view themselves as wageworkers tend to be left unserved.

Update on the epidemiology of work-related traumatic brain injury: a systematic review and meta-analysis

BACKGROUND

Traumatic brain injury (TBI) is a public health concern that can occur in a range of contexts. Work-related TBI (wrTBI) is particularly concerning. Despite overall work-related injury claims decreasing, the proportion of claims that are wrTBI have increased, suggesting prevention and support of wrTBI requires ongoing attention.

OBJECTIVES

This review aimed to provide updated information on the burden and risk factors of wrTBI among the working adult population.

METHODS

Medline, Embase, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched using a combination of TBI, work, and epidemiology text words and medical subject headings. Two reviewers independently assessed articles for inclusion. Meta-analyses were conducted to estimate prevalence and mortality of wrTBI and a narrative synthesis was conducted to provide additional context.

RESULTS

Pooled proportions meta-analyses estimate that 17.9% of TBIs were work-related and 6.3% of work-related injuries resulted in TBI, with 3.6% of wrTBI resulting in death. Populations of wrTBI were predominantly male (76.2%) and were 40.4 years of age, on average. The most commonly reported industries for wrTBI were education and training, healthcare and social assistance, construction, manufacturing, and transportation. Falls, being struck by an object or person, motor vehicle collisions, and assaults were the most commonly reported mechanisms of wrTBI.

CONCLUSIONS

A better understanding of the epidemiology of wrTBI can inform prevention and management strategies. This review highlights existing gaps, including a notable lack of sex or gender stratified data, to direct future investigation.

The role of occupational participation for people with traumatic brain injury: a systematic review of the literature

PURPOSE

Improving participation and quality of life is a desirable goal following traumatic brain injury (TBI). The purpose of this systematic review was to summarize existing findings concerning the role of occupational participation for persons with TBI.

METHODS

A systematic literature search using four electronic databases was followed by a review of all titles and abstracts. Articles were included if the studies were conducted with adults with TBI, used a qualitative methodology and explored the role or meaning of occupations and occupational participation from the perspectives of individuals with TBI. Following data extraction, a thematic synthesis was conducted.

RESULTS

A total of 642 articles were identified, of which 14 met all inclusion criteria. Three themes related to the role of occupations for people with TBI emerged: reflecting on change in occupational performance and occupational participation, occupational adaptation, and individual meaning of occupational participation.

CONCLUSION

The findings demonstrate the significance of occupational participation for people following TBI. Occupational participation enabled better understanding of one's abilities and limitations, assisted in occupational adaptation, and held unique meaning for participants. The findings also highlight the importance of providing long-term services focused on enabling participation in occupations in order to ensure successful adaptation following TBI.Implications for rehabilitationFor persons with TBI, occupational participation enables recognition of changes in their performance, contributes to the process of adaptation and identity (re)construction, fulfils various intrinsic needs and provides a sense of personal meaning.Rehabilitation professionals should recognize persons with TBI as occupational beings and work with individuals to identify the meaning of important occupations in the process of understanding and adapting to changes in capability, performance and participation.The rehabilitation process should focus on enabling persons to perform and participate in the occupations they want, need or are expected to do in their daily lives.National and regional health care systems should ensure that persons with TBI are provided with appropriate physical, social and institutional support and services in order to achieve meaningful occupational engagement.

How does chronic multimorbidity affect daily routines? An experience sampling study of community-dwelling adults in Hong Kong

Limited by conventional data collection methods, it is unclear how community-dwelling multimorbid people's daily routines are affected by their co-occurring illnesses. This study investigated the differences in everyday life schedules between multimorbid and nonmultimorbid people. Three hundred community-dwelling adults, representative of the Hong Kong Chinese population, provided real-time self-reports of daily routines over a 7-day study period. Stratified by baseline multimorbidity status, we implemented generalized linear mixed models (binomial) for each of the four outcomes: meal, chores, conversation, and work/school, with time intervals as independent variable and potential confounders adjusted. The odds of engaging in these activities were compared between multimorbid and nonmultimorbid participants by time intervals. Significant differences were identified. Unlike nonmultimorbid participants, late evening (22:00-24:00) was estimated to be the most frequently observed meal time among multimorbid participants (adjusted odds ratio [AOR] = 8.21, 95% confidence interval [CI] = 2.59-26.01 vs. 14:00-16:00), who also did chores significantly earlier in the morning (AOR = 1.97, 95% CI = 1.09-3.58 in 8:00-10:00 vs. 14:00-16:00). Conversations were significantly less likely among multimorbid participants throughout the day. Last, multimorbid participants seemed to have less typical working/schooling hours. Further studies are warranted to investigate how these disruptions may lead to lower levels of quality of life and poorer mental health.

Socioeconomic determinants of depression amid the anti-extradition bill protests in Hong Kong: the mediating role of daily routine disruptions

BACKGROUND

Previous research has suggested a socioeconomic gradient of mental health in the face of potentially traumatic events. Nevertheless, few studies examined the intermediary mechanisms of this gradient. This study tested a hypothesised mediating effect of disruptions to daily routines (eg, eating/sleeping habits) between socioeconomic status (SES) and depression among participants and non-participants of the anti-extradition bill protests in summer 2019 in Hong Kong.

METHODS

A territory-wide telephone survey was conducted during the movement in the first 3 weeks of July 2019 to collect self-report data from 1112 Cantonese-speaking Hong Kong citizens. Stratified by participation in the anti-extradition bill protests, logistic regression was conducted to examine the inverse relationship between SES and depression. Subsequently, path analysis was conducted to test the hypothesised indirect effect through daily routine disruptions.

RESULTS

In total, 581 (52.2%) respondents participated in the anti-extradition bill protests. Logistic regression showed that higher educational attainment was protective of depression among both participants and non-participants, while the protective effect of household income level HK$40 000-HK$79 999 (compared with <HK$20 000) was only observed among participants. Path analysis showed that 50.3% of the socioeconomic gradient was explained by daily routine disruptions among participants, compared with 8.3% among non-participants.

CONCLUSIONS

Daily routine disruptions partially explain the association between low SES and depression, especially among participants of the anti-extradition bill protests. To improve population mental health, such disruptions should be mitigated.

Older adults' perceptions of early rehabilitation and recovery after hip fracture surgery: a UK qualitative study

Purpose: To explore older adult's perceptions of early rehabilitation and recovery after hip fracture, as a complement to the UK standards for acute physiotherapy after hip fracture.Methods: In-depth semi-structured interviews with 15 adults aged 60 years or more in hospital after hip fracture surgery. A thematic analysis approach with interpretation informed by Bury's biographical disruption theoretical framework.Results: Participants voiced the importance of self-determination, professional support, meaningful feedback, and social capital after hip fracture. Collaborative working with staff was required for meeting the UK standards. Participants voiced anxieties about their hip fracture when considered in conjunction with their age and co-existing conditions, anticipating a disruption to their previous physical and social activities. This new, more dependent, life situation was not acceptable to participants.Conclusions: This study suggests hip fracture alone, was not perceived as a biographical disruption by older adults although it is presented as a potential tipping point in the loss of independence, contributing to the wider disruption of advancing age and co-existing conditions. For successful implementation of the UK standards, goal setting should consider patients in the wider context of their advancing age and co-existing conditions to empower them to define a fresh narrative of self.Implications for rehabilitationHip fracture was perceived as a potential tipping point in the loss of independence, contributing to the wider disruption of advancing age and co-existing conditions.Participants expressed uncertainty over their ability to recover their previous identity in the absence of professional support and/or social capital.Healthcare professionals need to educate and empower older adults to take charge of their own recovery.For successful implementation of the UK standards for acute physiotherapy, there is a need to contextualize goal setting to empower patients to define a fresh narrative of self.

The experience of occupational identity disruption post stroke: a systematic review and meta-ethnography

PURPOSE

After a stroke, most individuals cannot participate in some of their valued occupations, disrupting their occupational identity. The aim of this interpretive synthesis is to systematically review the existing body of research to develop an understanding of the experience of occupational identity disruption post-stroke.

METHODS

A systematic review of the literature that included nine electronic databases, reference lists screening and grey literature checking was completed. Ten studies published between January 2012 and October 2018 were included. Meta-ethnography was used for the interpretive synthesis.

FINDINGS

A three-staged process model was created. Stage 1 illustrates the four factors involved in occupational identity disruption: "A fragmented and externalized body", "losing control, freedom and independence", "changed social and familial interactions", and "occupational participation loss". Stage two explains the experience of occupational identity disruption: "Occupational identity loss", "a de-valued self", and "threat to identity continuity". Stage three shows the individual's coping strategies: "protecting one's self", "social isolation", and "re-inventing one's occupational self".

CONCLUSIONS

Stroke impacts on an individual's occupational identity, compromising the continuity of a stroke survivor's sense of self. However, occupational identity is fluid; this can be used to support individuals to re-invent the occupational self. A conceptual model was developed to support the application of these results in clinical practice.Implications for rehabilitationOccupational identity disruption impacts on stroke survivors' self-value and sense of self continuity.Health care professionals' understanding of stroke survivors experience of occupational identity disruption could contribute to realign stroke survivors and clinicians' rehabilitation goals.Occupational participation and social interaction should be core aspects of stroke rehabilitation.Occupation-focus rehabilitation could provide opportunities for stroke survivors to pursue their desired occupational identity.

Labour market attachment after mild traumatic brain injury: nationwide cohort study with 5-year register follow-up in Denmark

OBJECTIVES

Sickness absence after mild traumatic brain injury (mTBI) is frequent due to postconcussive symptoms. We examined labour market attachment following mTBI up to 5 years postinjury.

DESIGN AND SETTING

Nationwide cohort study with register follow-up.

PARTICIPANTS

Patients between 18 and 60 years with mTBI (International Classification of Diseases, version 10 diagnosis S06.0) were extracted from the Danish National Patient Register (n=19 732). Controls were matched on sex, age and municipality (n=18 640). Patients with spinal cord and column injuries, traumatic brain injury and concussions 5 years preinjury or as secondary diagnosis to the concussion in the inclusion period were excluded.

PRIMARY AND SECONDARY OUTCOME MEASURES

Data were extracted from the Danish Register for Evaluation of Marginalization. Primary outcome was 'not attending ordinary work' defined as receiving any social transfer payment. Secondary outcomes were health-related benefits, limited attachment to the labour market, permanent lack of attachment to the labour market and death.

RESULTS

5 years after diagnosis, 43% of patients were not attending ordinary work. The odds increased from 6 months (OR 1.30, 95% CI 1.24 to 1.36) to 5 years (OR 1.54, 95% CI 1.45 to 1.63). The odds of health-related benefits were 32% (OR 1.32, 95% CI 1.22 to 1.42) at 6 months and 22% (OR 1.22, 95% CI 1.12 to 1.33) at 5 years. Limited attachment to the labour market showed increased odds at 5 years (OR 1.38, 95% CI 1.27 to 1.51) and the odds of permanent lack of attachment to the labour market were higher for patients compared with controls (OR 2.59, 95% CI 2.30 to 2.92). Death was more than two times higher at 5 years postinjury (OR 2.62, 95% CI 2.10 to 3.26).

CONCLUSIONS

43% of concussed patients were not attending ordinary work 5 years postinjury and received health and social transfer benefits. We conclude that mTBI has a long-term impact on labour market attachment. Prevention and treatment of persisting postconcussive symptoms should be considered.

Population-based cohort study of the impacts of mild traumatic brain injury in adults four years post-injury

There is increasing evidence that some people can experience persistent symptoms for up to a year following mild TBI. However, few longitudinal studies of mild TBI exist and the longer-term impact remains unclear. The purpose of this study is to determine if there are long-term effects of mild traumatic brain injury (TBI) four-years later. Adults (aged ≥16 years) identified as part of a TBI incidence study who experienced a mild-TBI four-years ago (N = 232) were compared to age-sex matched controls (N = 232). Sociodemographic variables, prior TBI and symptoms were assessed at the time of injury. Four years post-injury participants completed the Rivermead Post-Concussion Symptom Questionnaire, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index and the Participation Assessment with Recombined Tools. Analysis of covariance was used to compare differences between TBI cases four years post-injury and controls, controlling for prior TBI and depression. A multiple regression model was used to identify the predictors of increased symptoms and reduced participation. The mild-TBI sample experienced significantly increased self-reported cognitive symptoms (F = 19.90, p = <0.01) four years post-injury than controls. There were no differences between the groups for somatic (F = 0.02, p = 0.89) or emotional symptoms (F = 0.31, p = 0.58). Additionally, the mild-TBI group reported significantly poorer community participation across all three domains: productivity (F = 199.07, p = <0.00), social relations (F = 13.93, p = <0.00) and getting out and about (F = 364.69, p = <0.00) compared to controls. A regression model accounting for 41% of the variance in cognitive symptoms in TBI cases revealed a history of TBI, receiving acute medical attention and baseline cognitive symptoms, sleep quality, anxiety and depression were predictive of outcome. The results indicate that whilst somatic and emotional symptoms resolve over time, cognitive symptoms can become persistent and that mild TBI can impact longer-term community participation. Early intervention is needed to reduce the longer-term impact of cognitive symptoms and facilitate participation.
