RESUMEN
OBJECTIVE: The long-term consequences of traumatic brain injury (TBI) on brain structure remain uncertain. Given evidence that a single significant brain injury event increases the risk of dementia, brain-age estimation could provide a novel and efficient indexing of the long-term consequences of TBI. Brain-age procedures use predictive modeling to calculate brain-age scores for an individual using structural magnetic resonance imaging (MRI) data. Complicated mild, moderate, and severe TBI (cmsTBI) is associated with a higher predicted age difference (PAD), but the progression of PAD over time remains unclear. We sought to examine whether PAD increases as a function of time since injury (TSI) and if injury severity and sex interacted to influence this progression. METHODS: Through the ENIGMA Adult Moderate and Severe (AMS)-TBI working group, we examine the largest TBI sample to date (n = 343), along with controls, for a total sample size of n = 540, to replicate and extend prior findings in the study of TBI brain age. Cross-sectional T1w-MRI data were aggregated across 7 cohorts, and brain age was established using a similar brain age algorithm to prior work in TBI. RESULTS: Findings show that PAD widens with longer TSI, and there was evidence for differences between sexes in PAD, with men showing more advanced brain age. We did not find strong evidence supporting a link between PAD and cognitive performance. INTERPRETATION: This work provides evidence that changes in brain structure after cmsTBI are dynamic, with an initial period of change, followed by relative stability in brain morphometry, eventually leading to further changes in the decades after a single cmsTBI.

BACKGROUND: Headache is a prevalent and debilitating symptom following traumatic brain injury (TBI). Large-scale, prospective cohort studies are needed to establish long-term headache prevalence and associated factors after TBI. This study aimed to assess the frequency and severity of headache after TBI and determine whether sociodemographic factors, injury severity characteristics, and pre- and post-injury comorbidities predicted changes in headache frequency and severity during the first 12 months after injury. METHODS: A large patient sample from the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) prospective observational cohort study was used. Patients were stratified based on their clinical care pathway: admitted to an emergency room (ER), a ward (ADM) or an intensive care unit (ICU) in the acute phase. Headache was assessed using a single item from the Rivermead Post-Concussion Symptoms Questionnaire measured at baseline, 3, 6 and 12 months after injury. Mixed-effect logistic regression analyses were applied to investigate changes in headache frequency and associated predictors. RESULTS: A total of 2,291 patients responded to the headache item at baseline. At study enrolment, 59.3% of patients reported acute headache, with similar frequencies across all strata. Female patients and those aged up to 40 years reported a higher frequency of headache at baseline compared to males and older adults. The frequency of severe headache was highest in patients admitted to the ICU. The frequency of headache in the ER stratum decreased substantially from baseline to 3 months and remained from 3 to 6 months. Similar trajectory trends were observed in the ICU and ADM strata across 12 months. Younger age, more severe TBI, fatigue, neck pain and vision problems were among the predictors of more severe headache over time. More than 25% of patients experienced headache at 12 months after injury. CONCLUSIONS: Headache is a common symptom after TBI, especially in female and younger patients. It typically decreases in the first 3 months before stabilising. However, more than a quarter of patients still experienced headache at 12 months after injury. Translational research is needed to advance the clinical decision-making process and improve targeted medical treatment for headache. TRIAL REGISTRATION: ClinicalTrials.gov NCT02210221.

BACKGROUND: Traumatic brain injury (TBI) represents a financial burden to the healthcare system, patients, their families and society. Rehabilitation interventions with the potential for reducing costs associated with TBI are demanded. This study evaluated the cost-effectiveness of a randomized, controlled, parallel group trial that compared the effectiveness of a combined cognitive and vocational intervention to treatment as usual (TAU) on vocational outcomes. METHODS: One-hundred sixteen participants with mild-to-moderate TBI were recruited from an outpatient clinic at Oslo University Hospital, Norway. They were randomized to a cognitive rehabilitation intervention (Compensatory Cognitive Training, CCT) and Supported Employment (SE) or TAU in a 1:1 ratio. Costs of CCT-SE and TAU, healthcare services, informal care and productivity loss were assessed 3, 6 and 12 months after study inclusion. Cost-effectiveness was evaluated from the difference in number of days until return to pre-injury work levels between CCT-SE and TAU and quality-adjusted life years (QALYs) derived from the EQ-5D-5L across 12 months follow-up. Cost-utility was expressed in incremental cost-effectiveness ratio (ICER). RESULTS: The mean total costs of healthcare services was 3,281 in the CCT-SE group and 2,300 in TAU, informal care was 2,761 in CCT-SE and 3,591 in TAU, and productivity loss was 30,738 in CCT-SE and 33,401 in TAU. Costs related to productivity loss accounted for 84% of the total costs. From a healthcare perspective, the ICER was 56 per day earlier back to work in the CCT-SE group. Given a threshold of 27,500 per QALY gained, adjusting for baseline difference in EQ-5D-5L index values revealed a net monetary benefit (NMB) of -561 (0.009*27,500-979) from the healthcare perspective, indicating higher incremental costs for the CCT-SE group. From the societal perspective, the NMB was 1,566 (0.009*27,500-(-1,319)), indicating that the CCT-SE intervention was a cost-effective alternative to TAU. CONCLUSIONS: Costs associated with productivity loss accounted for the majority of costs in both groups and were lower in the CCT-SE group. The CCT-SE intervention was a cost-effective alternative to TAU when considering the societal perspective, but not from a healthcare perspective. TRIAL REGISTRATION: ClinicalTrails.gov NCT03092713 .

BACKGROUND: Despite existing guidelines for managing mild traumatic brain injury (mTBI), evidence-based treatments are still scarce and large-scale studies on the provision and impact of specific rehabilitation services are needed. This study aimed to describe the provision of rehabilitation to patients after complicated and uncomplicated mTBI and investigate factors associated with functional outcome, symptom burden, and TBI-specific health-related quality of life (HRQOL) up to six months after injury. METHODS: Patients (n = 1379) with mTBI from the Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) study who reported whether they received rehabilitation services during the first six months post-injury and who participated in outcome assessments were included. Functional outcome was measured with the Glasgow Outcome Scale - Extended (GOSE), symptom burden with the Rivermead Post Concussion Symptoms Questionnaire (RPQ), and HRQOL with the Quality of Life after Brain Injury - Overall Scale (QOLIBRI-OS). We examined whether transition of care (TOC) pathways, receiving rehabilitation services, sociodemographic (incl. geographic), premorbid, and injury-related factors were associated with outcomes using regression models. For easy comparison, we estimated ordinal regression models for all outcomes where the scores were classified based on quantiles. RESULTS: Overall, 43% of patients with complicated and 20% with uncomplicated mTBI reported receiving rehabilitation services, primarily in physical and cognitive domains. Patients with complicated mTBI had lower functional level, higher symptom burden, and lower HRQOL compared to uncomplicated mTBI. Rehabilitation services at three or six months and a higher number of TOC were associated with unfavorable outcomes in all models, in addition to pre-morbid psychiatric problems. Being male and having more than 13 years of education was associated with more favorable outcomes. Sustaining major trauma was associated with unfavorable GOSE outcome, whereas living in Southern and Eastern European regions was associated with lower HRQOL. CONCLUSIONS: Patients with complicated mTBI reported more unfavorable outcomes and received rehabilitation services more frequently. Receiving rehabilitation services and higher number of care transitions were indicators of injury severity and associated with unfavorable outcomes. The findings should be interpreted carefully and validated in future studies as we applied a novel analytic approach. TRIAL REGISTRATION: ClinicalTrials.gov NCT02210221.

OBJECTIVES: To compare neuropsychological performances between patients with and without intracranial abnormalities after mild traumatic brain injury (mTBI) and assess the relationship between demographics, injury severity, and self-reported symptom characteristics with improvements in memory and executive functions (8 weeks to 1 year postinjury). SETTING: Inpatient/outpatient followed up at the Department of Physical Medicine and Rehabilitation, Oslo, Norway. PARTICIPANTS: Patients were divided into groups of complicated (n = 73) or uncomplicated mTBIs (n = 77) based on intracranial findings on computed tomographic or magnetic resonance imaging brain scans. DESIGN: Prospective, longitudinal cohort study. MAIN MEASURES: Neuropsychological assessments of memory and executive functions, self-reports of postconcussion, depression, posttraumatic stress symptoms, and general functioning at 8 weeks and 1 year postinjury. RESULTS: Longitudinal data showed that patients with complicated and uncomplicated mTBIs had similar cognitive performance and improvements. Hierarchical linear modeling revealed that individuals with early posttraumatic stress disorder and/or depressive symptoms performed worse on measures of Memory functions, and those with younger age (<40 years) and lower education (<12 years) performed worse on measures of Executive functions. CONCLUSION: Findings are suggestive of a good cognitive outcome following complicated and uncomplicated mTBIs. Early assessments of posttraumatic stress disorder and depression seem useful in identifying those most vulnerable having poorer cognitive outcomes, providing further interventions that may affect emotional and cognitive recovery.

OBJECTIVE: To evaluate the efficacy of a multidisciplinary outpatient follow-up programme compared to follow-up by a general practitioner for patients being at-risk or sick-listed with persistent post-concussion symptoms two months after a mild traumatic brain injury. DESIGN: Randomised controlled trial. PATIENTS: One hundred fifty-one patients, 16-56 years. METHODS: Multidisciplinary outpatient rehabilitation with individual contacts and a psycho-educational group intervention at two outpatient rehabilitation clinics compared to follow-up by a general practitioner after the multidisciplinary examination. Primary outcome was sustainable return-to-work first year post-injury. Secondary outcomes were post-concussion symptoms, disability, the patient's impressions of change and psychological distress. RESULTS: Days to sustainable return-to-work was 90 in the intervention and 71 in the control group (p = 0.375). The number of post-concussion symptoms were fewer in the intervention (6) compared to the control group (8) at 12 months (p = 0.041). No group differences were observed for disability (p = 0.193), patients impression of change (p = 0.285) or psychological distress (p = 0.716). CONCLUSION: The multidisciplinary outpatient follow-up programme focusing on better understanding and reassurance of favourable outcome for mild traumatic brain injury did not improve return-to-work, but may have reduced the development of post-concussion symptoms. Additional studies should focus on which factors exhibit a direct impact on return-to-work.

OBJECTIVE: This study sought to identify potential differing clinical characteristics between patients with a mild traumatic brain injury (MTBI) who attended a planned follow-up session and not. This study investigated whether clinical characteristics and attendance for a planned follow-up service 2-months after injury could be related to return-to-work (RTW) 1-year later. METHOD: Prospective cohort study of 343 patients with MTBI admitted consecutively to the Department of Neurosurgery in 2009-2011. Demographic and clinical data were obtained from the hospital files and data about sick leave from The Norwegian Labour and Welfare Service. Patients were categorized into two groups according to their attendance. RESULTS: One hundred and sixty-one (67%) patients attended (AG) and 80 (33%) did not (NAG) attend their follow-up appointments. The AG had significantly more frequently intracranial pathology on CT scan, had consumed less alcohol and were older. Logistic regression showed that follow-up attendance (OR = 16.89) and sick leave before injury (OR = 9.70) are unfavourably related to RTW at 12-months. Skull fracture and cause of injury had no influence of the outcome. CONCLUSION: Not attending the follow-up has a favourable outcome after MBTI, indicating that these patients have a reduced need for medical and rehabilitation support for their brain injury.

ABSTRACT: Patients with physical traumatic injuries frequently require long-term rehabilitation services. To strengthen rehabilitation services in the postacute phase, we need to assess characteristics of this population and their healthcare and rehabilitation needs in the community. This brief report summarizes the frequency of unmet rehabilitation needs in community-based rehabilitation during the first year after moderate and severe trauma. Additionally, the associations between sociodemographic, injury severity factors and unmet needs were examined. Data from a prospective multicenter cohort study of patients with moderate and severe trauma (New Injury Severity Score > 9) of all ages, discharged alive from two regional trauma centers in 2020 were used. Needs were estimated using the Needs and Provision Complexity Scale. Overall, 46% of patients had unmet needs at 12-mo postinjury, particularly related to the provision of rehabilitation services, specialist follow-ups, and social and family support. The probability of unmet needs was associated with age, preinjury comorbidities, and impaired functioning. Our findings support strategies targeting younger patients, those with preinjury comorbidities, and those with higher levels of disability and provide a starting point for the development of standardized rehabilitation needs assessment and guidelines after injury.

OBJECTIVE: To describe the needs for subacute inpatient rehabilitation and community-based healthcare services, rehabilitation, and social support in patients with moderate-to-severe traumatic injury in the first 6 months post-injury. Further, to explore associations between sociodemographic and clinical characteristics and unmet needs. DESIGN: Multicentre prospective cohort study. SUBJECTS: Of 601 persons (75% males), mean (standard deviation) age 47 (21) years, admitted to trauma centres in 2020 with moderate-to-severe injury, 501 patients responded at the 6-month follow-up and thus were included in the analyses. METHODS: Sociodemographic and injury-related characteristics were recorded at inclusion. Estimation of needs was assessed with the Rehabilitation Complexity Scale Extended-Trauma and the Needs and Provision Complexity Scale on hospital discharge. Provision of services was recorded 6 months post-injury. Multivariable logistic regressions explored associations between baseline variables and unmet inpatient rehabilitation and community-based service needs. RESULTS: In total, 20% exhibited unmet needs for subacute inpatient rehabilitation, compared with 60% for community-based services. Predictors for unmet community-based service needs included residing in less central areas, profound injury severity, severe head injury, and rehabilitation referral before returning home. CONCLUSION: Inadequate provision of healthcare and rehabilitation services, particularly in the municipalities, resulted in substantial unmet needs in the first 6 months following injury.

OBJECTIVE: To evaluate adherence to 3 central operational recommendations for acute rehabilitation in the Norwegian trauma plan. METHODS: A prospective multi-centre study of 538 adults with moderate and severe trauma with New Injury Severity Score > 9. RESULTS: Adherence to the first recommendation, assessment by a physical medicine and rehabilitation physician within 72 h following admission to the intensive care unit (ICU) at the trauma centre, was documented for 18% of patients. Adherence to the second recommendation, early rehabilitation in the intensive care unit, was documented for 72% of those with severe trauma and ≥ 2 days ICU stay. Predictors for early rehabilitation were ICU length of stay and spinal cord injury. Adherence to the third recommendation, direct transfer of patients from acute ward to a specialized rehabilitation unit, was documented in 22% of patients, and occurred more often in those with severe trauma (26%), spinal cord injury (54%) and traumatic brain injury (39%). Being employed, having head or spinal chord injury and longer ICU stay were predictors for direct transfer to a specialized rehabilitation unit. CONCLUSION: Adherence to acute rehabilitation guidelines after trauma is poor. This applies to documented early assessment by a physical medicine and rehabilitation physician, and direct transfer from acute care to rehabilitation after head and extremity injuries. These findings indicate a need for more systematic integration of rehabilitation in the acute treatment phase after trauma.

This study aims to evaluate the global functional outcomes after moderate-to-severe traumatic injury at 6 and 12 months and to examine the sociodemographic and injury-related factors that predict these outcomes. A prospective cohort study was conducted in which trauma patients of all ages with a New Injury Severity Score > 9 who were discharged alive from two regional trauma centres in Norway over a one-year period (2020) were included. The Glasgow Outcome Scale Extended (GOSE) score was used to analyse the functional outcomes. Regression analyses were performed to investigate the predictors of the GOSE score. Follow-up assessments were obtained from approximately 85% of the 601 included patients at both time points. The mean (SD) GOSE score was 6.1 (1.6) at 6 months and 6.4 (1.6) at 12 months, which corresponds to an upper-moderate disability. One-half of the patients had a persistent disability at 12 months post-injury. The statistically significant predictors of a low GOSE score at both time points were more pre-injury comorbidity, a higher number of injuries, and higher estimated rehabilitation needs, whereas a thorax injury with an Abbreviated Injury Scale ≥ 3 predicted higher GOSE scores. A high Glasgow Coma Scale score at admission predicted a higher GOSE score at 6 months. This study strengthens the evidence base for the functional outcomes and predictors in this population.
RESUMEN
BACKGROUND: Previous studies have demonstrated that the trauma population has needs for rehabilitation services that are best provided in a continuous and coordinated way. The discharge destination after acute care is the second step to ensuring quality of care. There is a lack of knowledge regarding the factors associated with the discharge destination for the overall trauma population. This paper aims to identify sociodemographic, geographical, and injury-related factors associated with discharge destination following acute care at trauma centers for patients with moderate-to-severe traumatic injuries. METHODS: A multicenter, population-based, prospective study was conducted with patients of all ages with traumatic injury [New Injury Severity Score (NISS) > 9] admitted within 72 h after the injury to regional trauma centers in southeastern and northern Norway over a 1-year period (2020). RESULTS: In total, 601 patients were included; a majority (76%) sustained severe injuries, and 22% were discharged directly to specialized rehabilitation. Children were primarily discharged home, and most of the patients ≥ 65 years to their local hospital. Depending on the centrality of their residence [Norwegian Centrality Index (NCI) 1-6, where 1 is most central], we found that patients residing in NCI 3-4 and 5-6 areas sustained more severe injuries than patients residing in NCI 1-2 areas. An increase in the NISS, number of injuries, or a spinal injury with an Abbreviated Injury Scale (AIS) ≥ 3 was associated with discharge to local hospitals and specialized rehabilitation than to home. Patients with an AIS ≥ 3 head injury (RRR 6.1, 95% Confidence interval 2.80-13.38) were significantly more likely to be discharged to specialized rehabilitation than patients with a less severe head injury. Age < 18 years was negatively associated with discharge to a local hospital, while NCI 3-4, preinjury comorbidity, and increased severity of injuries in the lower extremities were positively associated. CONCLUSIONS: Two-thirds of the patients sustained severe traumatic injury, and 22% were discharged directly to specialized rehabilitation. Age, centrality of the residence, preinjury comorbidity, injury severity, length of hospital stay, and the number and specific types of injuries were factors that had the greatest influence on discharge destination.
RESUMEN
OBJECTIVE: To quantify potential changes in direct referral to early specialized rehabilitation during the COVID-19 pandemic and the injury pattern of patients hospitalized with traumatic brain injury (TBI) at a level 1 trauma centre. METHODS: In this registry-based study, data were retrieved from the Oslo TBI Registry-Neurosurgery and included adult patients with injury-related intracranial findings admitted to Oslo University Hospital (OUH). The study focused on a period of time when OUH was in any level of preparedness because of the COVID-19 pandemic; March 2020 to August 2021. For comparison, the study used patients hospitalized for TBI in 2018 and 2019. RESULTS: A total of 1,310 hospitalized patients with TBI were divided into 2 groups; pre-pandemic and pandemic. Direct referral to early rehabilitation was maintained. Patient volume remained stable, and there were no differences between the groups regarding patient characteristics and acute management, although there was a significantly higher proportion of TBIs secondary to electric scooter accidents in the pandemic group. Results from univariable and multivariable logistic regression showed a multifaceted reality, but younger age, none or mild preinjury comorbidity and severe disability due to TBI at discharge from acute care remained stable strong predictors of direct referral to rehabilitation. CONCLUSION: For patients with moderate-severe TBI, the direct pathway to early specialized rehabilitation was maintained during 2020-21. However, the pandemic continued and the long-term impact for rehabilitation services is not yet known.

BACKGROUND: Substantial variance exists in outcomes after mild traumatic brain injury (MTBI), and these differences are not fully explained by injury characteristics or severity. Genetic factors are likely to play a role in this variance. OBJECTIVES: The aim of this study was to examine associations between the apolipoprotein (APOE)-ε4 allele and memory measures at two months post-MTBI and to evaluate whether subjective cognitive and affective symptoms were associated with APOE-ε4 status. Based on previous research, it was hypothesized that APOE-ε4 carriers would show poorer verbal memory performance compared to APOE-ε4 non-carriers. METHODS: Neuropsychological data at two months post-injury and blood samples that could be used to assess APOE genotype were available for 134 patients with MTBI (mean age 39.2 years, 62% males, 37% APOE-ε4 carriers). All patients underwent computed tomography at hospital admission and magnetic resonance imaging four weeks post-injury. RESULTS: The APOE-ε4 + status was associated with decreased immediate memory recall (p = 0.036; ß = -0.10, 95% CI [-0.19, -0.01]). Emotional, cognitive, and everyday executive function symptoms at two months post-injury were significantly higher in APOE-ε4 carriers compared to non-carriers. CONCLUSION: The APOE-ε4+ allele has a negative effect on verbal memory and symptom burden two months after MTBI.

RESUMEN
Previous research has demonstrated that early initiation of rehabilitation and direct care pathways improve outcomes for patients with severe traumatic brain injury (TBI). Despite this knowledge, there is a concern that a number of patients are still not included in the direct care pathway. The study aim was to provide an updated overview of discharge to rehabilitation following acute care and identify factors associated with the direct pathway. We analyzed data from the Oslo TBI Registry-Neurosurgery over a five-year period (2015-2019) and included 1724 adults with intracranial injuries. We described the patient population and applied multivariable logistic regression to investigate factors associated with the probability of entering the direct pathway. In total, 289 patients followed the direct pathway. For patients with moderate-severe TBI, the proportion increased from 22% to 35% during the study period. Significant predictors were younger age, low preinjury comorbidities, moderate-severe TBI and disability due to TBI at the time of discharge. In patients aged 18-29 years, 53% followed the direct pathway, in contrast to 10% of patients aged 65-79 years (moderate-severe TBI). This study highlights the need for further emphasis on entering the direct pathway to rehabilitation, particularly for patients aged >64 years.
RESUMEN
BACKGROUND: Apolipoprotein E (APOE) É4 is associated with poor outcome following moderate to severe traumatic brain injury (TBI). There is a lack of studies investigating the influence of APOE É4 on intracranial pathology following mild traumatic brain injury (MTBI). This study explores the association between APOE É4 and MRI measures of brain age prediction, brain morphometry, and diffusion tensor imaging (DTI). METHODS: Patients aged 16 to 65 with acute MTBI admitted to the trauma center were included. Multimodal MRI was performed 12 months after injury and associated with APOE É4 status. Corrections for multiple comparisons were done using false discovery rate (FDR). RESULTS: Of included patients, 123 patients had available APOE, volumetric, and DTI data of sufficient quality. There were no differences between APOE É4 carriers (39%) and non-carriers in demographic and clinical data. Age prediction revealed high accuracy both for the DTI-based and the brain morphometry based model. Group comparisons revealed no significant differences in brain-age gap between É4 carriers and non-carriers, and no significant differences in conventional measures of brain morphometry and volumes. Compared to non-carriers, APOE É4 carriers showed lower fractional anisotropy (FA) in the hippocampal part of the cingulum bundle, which did not remain significant after FDR adjustment. CONCLUSION: APOE É4 carriers might be vulnerable to reduced neuronal integrity in the cingulum. Larger cohort studies are warranted to replicate this finding.
RESUMEN
BACKGROUND: Returning to work is often a primary rehabilitation goal after traumatic brain injury (TBI). However, the evidence base for treatment options regarding return to work (RTW) and stable work maintenance remains scarce. OBJECTIVE: This study aimed to examine the effect of a combined cognitive and vocational intervention on work-related outcomes after mild-to-moderate TBI. METHODS: In this study, we compared 6 months of a combined compensatory cognitive training and supported employment (CCT-SE) intervention with 6 months of treatment as usual (TAU) in a randomised controlled trial to examine the effect on time to RTW, work percentage, hours worked per week and work stability. Eligible patients were those with mild-to-moderate TBI who were employed ≥50% at the time of injury, 18 to 60 years old and sick-listed ≥50% at 8 to 12 weeks after injury due to post-concussion symptoms, assessed by the Rivermead Post Concussion Symptoms Questionnaire. Both treatments were provided at the outpatient TBI department at Oslo University Hospital, and follow-ups were conducted at 3, 6 and 12 months after inclusion. RESULTS: We included 116 individuals, 60 randomised to CCT-SE and 56 to TAU. The groups did not differ in characteristics at the 12-month follow-up. Overall, a high proportion had returned to work at 12 months (CCT-SE, 90%; TAU, 84%, P=0.40), and all except 3 were stably employed after the RTW. However, a significantly higher proportion of participants in the CCT-SE than TAU group had returned to stable employment at 3 months (81% vs. 60%, P=0.02). CONCLUSION: These results suggest that the CCT-SE intervention might help patients with mild-to-moderate TBI who are still sick-listed 8 to 12 weeks after injury in an earlier return to stable employment. However, the results should be replicated and a cost-benefit analysis performed before concluding.

BACKGROUND: Traumatic injuries, defined as physical injuries with sudden onset, are a major public health problem worldwide. There is a paucity of knowledge regarding rehabilitation needs and service provision for patients with moderate and major trauma, even if rehabilitation research on a spectrum of specific injuries is available. OBJECTIVE: This study aims to describe the prevalence of rehabilitation needs, the provided services, and functional outcomes across all age groups, levels of injury severity, and geographical regions in the first year after trauma. Direct and indirect costs of rehabilitation provision will also be assessed. The overarching aim is to better understand where to target future efforts. METHODS: This is a population-based prospective follow-up study. It encompasses patients of all ages with moderate and severe acute traumatic injury (New Injury Severity Score >9) admitted to the regional trauma centers in southeastern and northern Norway over a 1-year period (2020). Sociodemographic and injury data will be collected. Upon hospital discharge, rehabilitation physicians estimate rehabilitation needs. Rehabilitation needs are assessed by the Rehabilitation Complexity Scale Extended-Trauma (RCS E-Trauma; specialized inpatient rehabilitation), Needs and Provision Complexity Scale (NPCS; community-based rehabilitation and health care service delivery), and Family Needs Questionnaire-Pediatric Version (FNQ-P). Patients, family caregivers, or both will complete questionnaires at 6- and 12-month follow-ups, which are supplemented by telephone interviews. Data on functioning and disability, mental health, health-related quality of life measured by the EuroQol Questionnaire (EQ-5D), and needs and provision of rehabilitation and health care services are collected by validated outcome measures. Unmet needs are represented by the discrepancies between the estimates of the RCS E-Trauma and NPCS at the time of a patient's discharge and the rehabilitation services the patient has actually received. Formal service provision (including admission to inpatient- or outpatient-based rehabilitation), informal care, and associated costs will be collected. RESULTS: The project was funded in December 2018 and approved by the Regional Committee for Medical and Health Research Ethics in October 2019. Inclusion of patients began at Oslo University Hospital on January 1, 2020, and at the University Hospital of North Norway on February 1, 2020. As of February 2021, we have enrolled 612 patients, and for 286 patients the 6-month follow-up has been completed. Papers will be drafted for publication throughout 2021 and 2022. CONCLUSIONS: This study will improve our understanding of existing service provision, the gaps between needs and services, and the associated costs for treating patients with moderate and major trauma. This may guide the improvement of rehabilitation and health care resource planning and allocation. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/25980.
RESUMEN
The global burden of mortality and morbidity caused by traumatic brain injury (TBI) is significant, and the heterogeneity of TBI patients and the relatively small sample sizes of most current neuroimaging studies is a major challenge for scientific advances and clinical translation. The ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Adult moderate/severe TBI (AMS-TBI) working group aims to be a driving force for new discoveries in AMS-TBI by providing researchers world-wide with an effective framework and platform for large-scale cross-border collaboration and data sharing. Based on the principles of transparency, rigor, reproducibility and collaboration, we will facilitate the development and dissemination of multiscale and big data analysis pipelines for harmonized analyses in AMS-TBI using structural and functional neuroimaging in combination with non-imaging biomarkers, genetics, as well as clinical and behavioral measures. Ultimately, we will offer investigators an unprecedented opportunity to test important hypotheses about recovery and morbidity in AMS-TBI by taking advantage of our robust methods for large-scale neuroimaging data analysis. In this consensus statement we outline the working group's short-term, intermediate, and long-term goals.
