Combined cognitive and vocational rehabilitation after mild-to-moderate traumatic brain injury: A randomized controlled trial

This thesis describes a combined cognitive and vocational intervention aimed at improving work participation after mild-to-moderate traumatic brain injury (TBI). The aims of this thesis were to describe a sample of patients who sought medical rehabilitation due to post-concussive symptoms 8–12 weeks after injury, to evaluate the effect of a combined cognitive and vocational intervention on work participation and examine the predictive value of work-related factors on work participation. The study included 116 participant who were still sick listed due to post-concussive symptoms 8–12 weeks after TBI. Sixty patients were randomized to the combined cognitive and vocational intervention, while 56 received follow-up at a specialized TBI rehabilitation outpatient clinic. Significantly more patients in the combined cognitive and vocational group had returned to work after 3 months. This thesis also demonstrated that work-related factors, as psychosocial work environment and sector of employment, predicted work participation after 1 year. This highlights the importance of considering work-related factors when aiming to return to work after a mild-to-moderate TBI

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

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

What characterizes work and workplaces that retain their employees following acquired brain injury? A systematic review.

Objectives: The objective of this study was to conduct a systematic review assessing workplace factors related to work retention (or return to work) in employees with acquired brain injury (ABI). Additionally, we aimed to synthesise the evidence and state of knowledge on this subject. Methods: A database search was performed in nine relevant electronic databases. Inclusion criteria were quantitative peer-reviewed publications empirically investigating the relationship between work/workplace factors and work retention in employees following ABI. The methodological quality was determined by Effective Public Health Practice Project scoring, and evidence was synthesised narratively. Results: Thirteen studies were included. We found moderate evidence for a negative relationship between manual work and work retention. We also found limited evidence for a U-shaped relationship between workload and complete work retention at 6 months and no relationship at 12 months; a positive relationship between managers, compared with non-managers, and faster work retention; a positive relationship between large enterprise size defined as ≥250 employees, and no relationship between large enterprise size, defined as ≥1000 employees, and work retention. Conclusion: Relative to individual factors, there is little evidence on specific workplace factors’ relationship to work retention among employees with ABI. For most workplace factors, there were too few high-quality studies to designate evidence as more than limited or insufficient. Future studies should replicate rigorous studies of well-defined modifiable workplace factors related to work retention

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
