Improving participation is an important aim in outpatient rehabilitation treatment. Knowledge regarding participation restrictions in children and young adults with acquired brain injury (ABI) is scarce and little is known regarding the differences in perspectives between patients and parents in the outpatient rehabilitation setting. The aims are to describe participation restrictions among children/young adults (5–24 years) with ABI and investigating differences between patients’ and parents’ perspectives. At admission in 10 rehabilitation centers, patients and parents were asked to complete the Child and Adolescent Scale of Participation (CASP; score 0–100; lower score = more restrictions) and injury/patient/family-related questions. CASP scores were categorized (full/somewhat-limited/limited/very-limited participation). Patient/parent-reported outcomes were compared using the Wilcoxon signed-rank test. 223 patients and 245 parents participated (209 paired-samples). Median patients’ age was 14 years (IQR; 11–16), 135 were female (52%), 195 had traumatic brain injury (75%). The median CASP score reported by patients was 82.5 (IQR: 67.5–90) and by parents 91.3 (IQR: 80.0–97.5) (difference = p < 0.05). The score of 58 patients (26%) and 25 parents (10%) was classified as ‘very-limited’. Twenty-six percent of children and young adults referred for rehabilitation after ABI had “very-limited” participation. Overall, parents rated their child’s participation better than patients themselves. Quantifying participation restrictions after ABI and considering both perspectives is important for outpatient rehabilitation treatment.

PurposeBrain injuries (traumatic-/nontraumatic, TBI/nTBI) in young patients may lead to problems e.g., decreased health-related quality of life (HRQoL), and causes family impact. Knowledge regarding the family impact and the relationship with patients' HRQoL over time is scarce. This follow-up study describes family impact/HRQoL and their mutual relationship in young patients (5-24 years) after TBI/nTBI.Materials and methodsParents of patients that were referred to outpatient rehabilitation completed the PedsQL (TM) Family-Impact-Module questionnaire to assess the family impact and the parent-reported PedsQL (TM) Generic-core-set-4.0 to assess patients' HRQoL (lower scores: more family impact/worse HRQoL). Questionnaires were completed at the time of referral to rehabilitation (baseline) and one/two years later (T1/T2). Linear-mixed models were used to examine family impact/HRQoL change scores, and repeated-measure correlations (r) to determine longitudinal relationships.ResultsTwo-hundred-forty-six parents participated at baseline, 72 (at T2), median patient's age at baseline was 14 years (IQR:11-16), and 181 (74%) had TBI. Mean (SD) PedsQL (TM) Family-Impact-Module score at baseline was 71.7 (SD:16.4) and PedsQL (TM) Generic-core-set-4.0: 61.4 (SD:17.0). Over time, PedsQL (TM) Family-Impact-Module scores remained stable, while PedsQL (TM) Generic-core-set-4.0 scores improved significantly(p < 0.05). A moderately strong longitudinal correlation was found between family impact&HRQoL (r = 0.51).ConclusionsFamily impact does not tend to decrease over time but remained a considerable problem, although patients' HRQoL improved. Next to focusing on patients' HRQoL, it remains important to consider family impact and offer family support throughout rehabilitation.

Purpose: To increase knowledge/awareness on family impact (FI) after acquired brain injury (ABI) in rehabilitation settings, it is essential to investigate the associations between patient-functioning and impact on families. This has been explored in hospital-based cohorts, but not in rehabilitation settings. Methods: A cross-sectional, multi-center study among parents of children/young adults (aged 5–24 years) with ABI referred to rehabilitation was performed. Patient/injury/family-characteristics were noted, and parents completed the PedsQL™Family-Impact-Module and PedsQL™generic-core-4.0 to assess FI and health-related quality of life (HRQoL). Univariate- and multivariable-regression analyses were performed to investigate associations between HRQoL/patient/injury/family-related factors and FI. Results: 246 families participated; patients’ median age was 14 year (IQR 11–16), 65 had non-traumatic-brain-injury (nTBI) (26%), 127 were female. FI was found to be considerable (median FIM-score 71.9, IQR:60–85). Especially referral to rehabilitation >6 months after onset, diminished patients’ mental/emotional health and HRQoL (child/family factors), and premorbid problems were associated with higher FI. Conclusions: In this rehabilitation cohort, pediatric ABI caused considerably higher FI than in hospital-based studies with referral to rehabilitation >6 months, diminished child/family factors and presence of premorbid problems increasing FI. Assessing and monitoring FI and its associated factors enables professionals to individualize treatment, psychoeducation, support and follow-up.

Acquired brain injury (ABI) may cause fatigue and participation restrictions in young patients. However, knowledge regarding the course of these problems over time is lacking. This study aims to describe the course of fatigue and participation and their relationship over time in an observational two-year follow-up study among patients(5-24 years) with ABI referred for outpatient rehabilitation and their parents. Patients/parents completed the PedsQL (TM) Multidimensional-Fatigue-Scale(PedsQL (TM) MFS, totalscore/3-domains) and the Child/Adolescent-Scale of Participation(CASP, totalscore/4-domains). Scores ranged from 0-100: lower scores = more fatigue/participation problems. Linear mixed models and repeated measures correlations were used to determine the course over time (change-scores/95%CI) and correlations between fatigue/participation. At baseline, 223 patients/246 parents participated with 94/104 at either T1, T2 or both. Median age was 15 years (IQR:12-17), 74% had a traumatic brain injury. Mean(SD) patient/parent-reported PedsQL (TM) MFS totalscores(baseline) were: 50.3(17.3) and 53.8(19.1), respectively. CASP totalscores were 78.0(16.4) and 87.1(13.6). Over time, patient-reported scores improved significantly (fatigue: + 8.8 (2.9;14.7), p < 0.05)/participation: + 10.5 (6.3;14.7), p < 0.05)). Similar results were found regarding parent-reported fatigue: + 8.7 (3.4;13.9), p < 0.05 but not regarding participation. Two years later, fatigue was still considerable(patients:59.1/parents:62.5). Moderate/fair correlations between fatigue/participation over time were found. Fatigue and participation in young patients with ABI improved two years after referral to rehabilitation. However, fatigue remained a considerable problem.

Purpose: Acquired brain injury (ABI) is prevalent among young people (4–25 years). When ABI-related problems persist, treatment in a rehabilitation center (RC) may be indicated. However, there is wide variability regarding the delivery of care across Dutch RCs, including assessments, interventions, and psychoeducational (PE) materials. The aim was to create a consensus-based framework with preferred assessments, interventions, and PE-materials to be used in pediatric ABI rehabilitation. A national framework could optimize the delivery of comparable care for this population. Methods: For this three-round Delphi study, healthcare professionals (physiatrists, psychologists, social workers, physical/occupational/speech/language therapists) from RCs providing care for young people with ABI were invited to participate. In the first two (online) rounds, currently used assessments/interventions/PE-materials were collected, stepwise-prioritized, subsequently listed per discipline, and classified per International Classification of Functioning (ICF) domain. Results from rounds one/two were discussed in a consensus meeting (in person), aiming to reach agreement on assessments/interventions/PE-materials in the national framework and how to use them in current practice. Results: Seventy-four healthcare professionals from 12 RCs participated. After Delphi round one, 163 assessments, 39 interventions, and 64 PE-materials were collected. After round two, the selection was narrowed down to n = 51/n = 34/n = 28, respectively. After round three, consensus was reached on 37 assessments, 25 interventions (divided over all disciplines/classified per ICF domain), 27 PE-materials, as well as on the use of the framework by all participating RC to enhance clinical reasoning in current practice. Conclusion: A consensus-based national framework in ABI rehabilitation has been developed and is now available to optimize the delivery of care for young people with ABI across Dutch RCs.
