Long-Term School Outcomes of Children and Adolescents With Traumatic Brain Injury.

ABSTRACT: OBJECTIVE:To better understand the impact of age at injury, severity of injury, and time since injury on long-term school outcomes of children with traumatic brain injury (TBI). PARTICIPANTS:Four groups of children: complicated mild/moderate TBI (n = 23), severe TBI (n = 56), orthopedic injury (n = 35), and healthy controls (n = 42). Children with TBI were either 2 years postinjury or 6 years postinjury. DESIGN:Cross-sectional design. MEASURES:School records as well as parental ratings of functional academic skills and school competency. RESULTS:Children with severe TBI had consistently high usage of school services and low school competency ratings than children with orthopedic injuries and healthy controls. In contrast, children with complicated-mild/moderate TBI were significantly more likely to receive school support services and have lower competence ratings at 6 years than at 2 years postinjury. Students injured at younger ages had lower functional academic skill ratings than those injured at older ages. CONCLUSIONS:These findings highlight the increasing academic challenges faced over time by students with complicated-mild/moderate TBI and the vulnerability of younger children to poorer development of functional academic skills.

Project description:ObjectivesTo investigate functional outcomes and state of consciousness at 1 year and ≥2 years postinjury in children who sustained a traumatic brain injury and were in a disorder of consciousness (DOC), either vegetative state (VS) or minimally conscious state (MCS), upon admission to inpatient rehabilitation.DesignRetrospective chart review.SettingPediatric inpatient rehabilitation unit.ParticipantsChildren aged 2-18 years (N=37) who were admitted to inpatient rehabilitation with admission scores <30 on the Cognitive and Linguistic Scale (CALS).InterventionsNot applicable.Main outcome measuresGlasgow Outcome Scale- Extended, Pediatric Revision (GOS-E Peds), and state of consciousness based on previously established guidelines.ResultsAt admission, 16 children were in VS (43.2%) and 21 (56.8%) were in MCS. Children admitted in VS had a significantly longer time from injury to inpatient rehabilitation admission, lower CALS admission scores, were more likely to be in a DOC ≥28 days, and had greater disability at both follow-up time points. At the 1-year follow-up, 3 patients were in VS, 7 were in MCS, and 27 had emerged from MCS. By the time of the most recent follow-up (≥2y), 2 more patients had emerged from MCS. Across the cohort, GOS-E Peds scores at 1 year ranged from VS (GOS-E Peds, 7) to upper moderate disability (GOS-E Peds, 3). Most patients were functioning in the lower severe disability category (GOS-E Peds, 6) at 1 year (43.2%) and at the time of the most recent follow-up (43.2%). Twenty-seven patients (73.0%) showed stable GOS-E Peds scores between the 2 time points, 6 (16.2%) improved, and 4 (10.8%) were deceased.ConclusionsAlthough a majority of patients emerged from a DOC by 1 year postinjury, most continued to demonstrate notable functional impairment at the 1-year follow-up that persisted to the most recent follow-up. A small subset demonstrated important improvements between 1 year and the most recent follow-up (2 patients emerged, 6 patients showed improvement in GOS-E Peds scores).

Project description:Background and aims: Severe traumatic brain injury is a leading cause of acquired persistent disabilities, and represents an important health and economic burden. However, the determinants of long-term outcome have rarely been systematically studied in a prospective longitudinal study of a homogeneous group of patients suffering exclusively from severe TBI Methods: Prospective observational study of an inception cohort of adult patients with severe traumatic brain injury in the Parisian area (PariS-TBI). Outcome was assessed with face-to-face interview 8 years after Traumatic Brain Injury, focusing on impairments, activity limitations, and participation restriction. Results: Five hundred and four patients were included between 2005 and 2007. At 8-year follow-up, 261 patients were deceased, 128 were lost to follow-up, 22 refused to participate, and 86 were finally evaluated. Age, gender, initial injury severity did not significantly differ between evaluated patients and lost to follow-up, but the latter were more frequently students or unemployed. Mean age was 41.9 (SD 13.6), 79% were male, median initial Glasgow Coma Scale Score was 6. The most frequent somatic complaints concerned balance (47.5%), motricity (31%), and headaches (36%), but these were less frequent than cognitive complaints (Memory 71%, Slowness 68%, Concentration 67%). According to the Hospital Anxiety and Depression Scale (HADS), 25 % had a score >8 for anxiety and 23.7% for depression. According to the Extended Glasgow Outcome Scale, 19.8% remained severely disabled, 46.5% moderately disabled, 33.7% had a good recovery. Older age, longer education duration, lower functional status upon intensive care discharge, and more severe 8-year dysexecutive problems were significantly associated with a lower Extended Glasgow Outcome Scale score in multivariable analysis. At 8 years, 48.7% of patients were employed in a productive job. Of those, 38% declared a salary loss since traumatic brain injury. Unemployment was significantly associated with lower 1-year GOSE score and more severe 8-year dysexecutive problems. Conclusions: These results from an inception cohort study highlight the fact that long-term outcome after severe TBI is determined by a complex combination of injury-related, demographic and neuropsychological factors. Long after the injury, persisting impairments still interfere with social integration, and participation.

Project description:The heterogeneity of traumatic brain injury (TBI) remains a core challenge for the success of interventional clinical trials. Data-driven approaches for patient stratification may help to identify TBI patient phenotypes during the acute injury period as well as facilitate targeted trial patient enrollment and analysis of treatment efficacy. In this study, we implemented an unsupervised machine learning approach to identify TBI subpopulations at injury baseline using data from 1213 TBI patients who participated in the Citicoline Brain Injury Treatment Trial (COBRIT) Trial. A wrapper framework utilizing generalized low-rank models automatically selected relevant clinical features that were subsequently used to cluster patients using a partitioning around medoids clustering algorithm. Using this approach, we identified three patient phenotypes with unique clinical injury profiles based on a subset of acute injury features. Phenotype-specific differences in long-term functional outcome trajectories were respectively observed at 3 and 6 months after injury. In comparison, when patients were grouped by baseline Glasgow Coma Scale (GCS), no differences in baseline clinical feature profiles or long-term outcomes were observed. To test phenotype reproducibility in an external validation data set, we used a K-nearest neighbors algorithm to classify subjects in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Pilot data set into corresponding phenotypes, then measured the Gower's dissimilarities between TRACK-TBI and COBRIT subjects in each phenotype. No significant differences were found between trial subjects within two phenotypes, suggesting that these phenotypes may be generalizable within a broad range of TBI severity. Further, Extended Glasgow Outcome Scale (GOS-E) outcomes in the TRACK-TBI data set similarly demonstrated phenotype-specific differences in long-term outcomes. Our results suggest that unsupervised machine learning is a promising and effective approach for discovery of novel injury subpopulations over the conventional GCS-based method, and may improve patient selection in future TBI clinical trials.
