Cost-Effectiveness Analysis of an Early-Initiated, Continuous Chain of Rehabilitation after Severe Traumatic Brain Injury

Recovery after moderate to severe TBI and factors influencing functional outcome: What you need to know

ABSTRACT

Traumatic brain injury (TBI) represents a major cause of death and disability, significantly impacting the lives of 2.5 million people annually in the United States. Long-term natural history studies have clarified that functional recovery continues for up to a decade, even among those who sustain severe TBI. Despite these findings, nihilistic attitudes regarding prognosis persist among clinicians, highlighting the need for improved understanding of the natural history of recovery from TBI and the factors that influence outcome. Recent advances in neuroimaging technologies and blood-based biomarkers are shedding new light on injury detection, severity classification and the physiologic mechanisms underlying recovery and decline postinjury. Rehabilitation is an essential component of clinical management after moderate to severe TBI and can favorably influence mortality and functional outcome. However, systemic barriers, including healthcare policy, insurance coverage and social determinants of health often limit access to inpatient rehabilitation services. Posttraumatic amnesia and confusion contribute to morbidity after TBI; however, early initiation and sustained provision of rehabilitation interventions optimize long-term outcome. Evidence-based reviews have clearly shown that cognitive rehabilitation strategies can effectively restore or compensate for the cognitive sequelae of TBI when used according to existing practice guidelines. Neurostimulant agents are commonly employed off-label to enhance functional recovery, however, only amantadine hydrochloride has convincingly demonstrated effectiveness when used under tested parameters. Noninvasive brain stimulation procedures, including transcranial direct current stimulation and transcranial magnetic stimulation, have emerged as promising treatments in view of their ability to modulate aberrant neuronal activity and augment adaptive neuroplasticity, but assessment of safety and effectiveness during the acute period has been limited. Understanding the natural history of recovery from TBI and the effectiveness of available therapeutic interventions is essential to ensuring appropriate clinical management of this complex population.

Cognitive and everyday functioning after bacterial brain abscess: a prospective study of functional recovery from 8 weeks to 1 year post-treatment

OBJECTIVE

A bacterial brain abscess may damage surrounding brain tissue by mass effect, inflammatory processes, and bacterial toxins. The aim of this study was to examine cognitive and functional outcomes at 8 weeks and 1 year following acute treatment.

METHODS

Prospective study of 20 patients with bacterial brain abscess (aged 17-73 years; 45% females) with neuropsychological assessment at 8 weeks and 1 year post-treatment. Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Patient Competence Rating Scale (PCRS) were used to assess everyday functioning and administered to patients and informants.

RESULTS

Cognitive impairment was found in 30% of patients at 8 weeks and 22% at 1 year. Significant improvements were seen on tests of perceptual reasoning, attention, verbal fluency, and motor abilities (p < 0.05). At 1 year, 45% had returned to full-time employment. Nevertheless, patients and their informants obtained scores within the normal range on measures of everyday functioning (PCRS and BRIEF-A) at 8 weeks and 1 year. No significant improvements on these measures emerged over time.

CONCLUSION

Residual long-term cognitive impairment and diminished work ability affected 22% and 45% of patients one year after BA. Persistent cognitive impairment emphasizes the importance of prompt acute treatment and cognitive rehabilitation.

The effectiveness and safety of centralized early rehabilitation care for critically ill children with severe acquired brain injury: A retrospective cohort and implementation study

BACKGROUND

Most children with neurocritical illness are at risk of physical, neurocognitive, and psychosocial sequelae and need centralized early rehabilitation care.

OBJECTIVE

To identify the effectiveness and safety of centralized early rehabilitation care for children with severe acquired brain injury.

METHODS

This is a mixed methods study-an implementation study and single-center retrospective cohort study with historical control. All children with severe acquired brain injury hospitalized in a specialized rehabilitation center in a comprehensive tertiary pediatric hospital between September 2016 and August 2020 were included. Patients treated in the centralized early rehabilitation unit were compared to historical controls dispersed in the normal inpatient rehabilitation ward. The effectiveness outcomes were measured by the Pediatric Cerebral Performance Category (PCPC) scale and the incidence of newly onset comorbidities. The safety outcomes were indicated by the mortality rate and the incidence of unexpected referrals.

RESULTS

One hundred seventy-five patients were included. The delta PCPC scores of the first 4 weeks of inpatient rehabilitation in the intervention group were significantly lower than the control group (Z = -2.395, p = 0.017). The PCPC scores at 1 year in the intervention group were significantly reduced as compared to the control group (Z = -3.337, p = 0.001). The incidence of newly onset pneumonia/bronchitis was also decreased in the intervention group (χ2 = 4.517, p = 0.034). No death of patients was recorded, and there was no significant difference in unexpected referral rate between the two groups (χ2 = 0.374, p = 0.541).

CONCLUSIONS

The centralized pediatrics early rehabilitation unit is effective and safe for children with severe acquired brain injury. Further multicenter prospective implementation studies on effectiveness, safety, and economic evaluation are needed.

Overview of randomized controlled trials of moderate to severe traumatic brain injury: A systematic review

BACKGROUND

Given the complexity of post-TBI medical, surgical, and rehabilitative care, research is critical to optimize interventions across the continuum of care and improve outcomes for persons with moderate to severe TBI.

OBJECTIVE

To characterize randomized controlled trials (RCTs) of moderate to severe traumatic brain injury (TBI) in the literature.

METHOD

Systematic searches of MEDLINE, PubMed, Scopus, CINAHL, EMBASE and PsycINFO for RCTs up to December 2022 inclusive were conducted in accordance with PRISMA guidelines.

RESULTS

662 RCTs of 91,946 participants published from 1978 to 2022 met inclusion criteria. The number of RCTs published annually has increased steadily. The most reported indicator of TBI severity was the Glasgow Coma Scale (545 RCTs, 82.3%). 432 (65.3%) RCTs focused on medical/surgical interventions while 230 (34.7%) addressed rehabilitation. Medical/surgical RCTs had larger sample sizes compared to rehabilitation RCTs. Rehabilitation RCTs accounted for only one third of moderate to severe TBI RCTs and were primarily conducted in the chronic phase post-injury relying on smaller sample sizes.

CONCLUSION

Further research in the subacute and chronic phases as well as increasing rehabilitation focused TBI RCTs will be important to optimizing the long-term outcomes and quality of life for persons living with TBI.

Access to Rehabilitation After Hospitalization for Traumatic Brain Injury: A National Longitudinal Cohort Study in Sweden

BACKGROUND

Rehabilitation is suggested to improve outcomes following traumatic brain injury (TBI), however, the extent of access to rehabilitation among TBI patients remains unclear.

OBJECTIVE

To examine the level of access to rehabilitation after TBI, and its association with health and sociodemographic factors.

METHOD

We conducted a longitudinal cohort study using Swedish nationwide healthcare and sociodemographic registers. We identified 15 880 TBI patients ≥18 years hospitalized ≥3 days from 2008 to 2012 who were stratified into 3 severity groups; grade I (n = 1366; most severe), grade II (n = 5228), and grade III (n = 9268; least severe). We examined registered contacts with specialized rehabilitation or geriatric care (for patients ≥65 years) during the hospital stay, and/or within 1 year post-discharge. We performed a generalized linear model analysis to estimate the risk ratio (RR) for receiving specialized rehabilitation or geriatric care after a TBI based on sociodemographic and health factors.

RESULTS

Among TBI patients, 46/35% (grade I), 14/40% (grade II), and 5/18% (grade III) received specialized rehabilitation or geriatric care, respectively. Being currently employed or studying was positively associated (RR 1.7, 2.3), while living outside of a city area was negatively associated (RR 0.36, 0.79) with receiving specialized rehabilitation or geriatric care. Older age and a prior substance use disorder were negatively associated with receiving specialized rehabilitation (RR 0.51 and 0.81).

CONCLUSION

Our results suggest insufficient and unequal access to rehabilitation for TBI patients, highlighting the importance of organizing and standardizing post-TBI rehabilitation to meet the needs of patients, regardless of their age, socioeconomic status, or living area.

"It gave her that soft landing": Consumer perspectives on a transitional rehabilitation service for adults with acquired brain injury

Transitional rehabilitation service models for people with acquired brain injury (ABI) may address sub-optimal support for individuals returning home after hospitalization for ABI. This study investigated perspectives of people with ABI and close others who received transitional rehabilitation. A qualitative study involving semi-structured interviews with 10 individuals with ABI and 12 associated close others was conducted as part of a mixed-method evaluation of an Australian transitional rehabilitation service (TRS) pilot project. Thematic analysis based on the Framework method was conducted independently by two researchers. Three broad themes illustrated participants' experience of the TRS: (1) structure after hospital discharge; (2) a "soft landing"; and (3) equipped for community living. Findings suggest that home-based, interdisciplinary transitional rehabilitation after hospital discharge was perceived as an important stage of rehabilitation by participants. Valued features relate to post-hospital rehabilitation structure: a single point of contact to facilitate organization and information exchange, a known discharge destination, and consistent communication; support and therapy within a familiar home environment; and being equipped with relevant knowledge and strategies to manage ongoing challenges. Further research exploring the experiences of individuals with ABI without close family or social support, and research capturing longitudinal outcomes from transitional rehabilitation is recommended.

Traumatic brain injury: progress and challenges in prevention, clinical care, and research

Traumatic brain injury (TBI) has the highest incidence of all common neurological disorders, and poses a substantial public health burden. TBI is increasingly documented not only as an acute condition but also as a chronic disease with long-term consequences, including an increased risk of late-onset neurodegeneration. The first Lancet Neurology Commission on TBI, published in 2017, called for a concerted effort to tackle the global health problem posed by TBI. Since then, funding agencies have supported research both in high-income countries (HICs) and in low-income and middle-income countries (LMICs). In November 2020, the World Health Assembly, the decision-making body of WHO, passed resolution WHA73.10 for global actions on epilepsy and other neurological disorders, and WHO launched the Decade for Action on Road Safety plan in 2021. New knowledge has been generated by large observational studies, including those conducted under the umbrella of the International Traumatic Brain Injury Research (InTBIR) initiative, established as a collaboration of funding agencies in 2011. InTBIR has also provided a huge stimulus to collaborative research in TBI and has facilitated participation of global partners. The return on investment has been high, but many needs of patients with TBI remain unaddressed. This update to the 2017 Commission presents advances and discusses persisting and new challenges in prevention, clinical care, and research.

In LMICs, the occurrence of TBI is driven by road traffic incidents, often involving vulnerable road users such as motorcyclists and pedestrians. In HICs, most TBI is caused by falls, particularly in older people (aged ≥65 years), who often have comorbidities. Risk factors such as frailty and alcohol misuse provide opportunities for targeted prevention actions. Little evidence exists to inform treatment of older patients, who have been commonly excluded from past clinical trials—consequently, appropriate evidence is urgently required. Although increasing age is associated with worse outcomes from TBI, age should not dictate limitations in therapy. However, patients injured by low-energy falls (who are mostly older people) are about 50% less likely to receive critical care or emergency interventions, compared with those injured by high-energy mechanisms, such as road traffic incidents.

Mild TBI, defined as a Glasgow Coma sum score of 13–15, comprises most of the TBI cases (over 90%) presenting to hospital. Around 50% of adult patients with mild TBI presenting to hospital do not recover to pre-TBI levels of health by 6 months after their injury. Fewer than 10% of patients discharged after presenting to an emergency department for TBI in Europe currently receive follow-up. Structured follow-up after mild TBI should be considered good practice, and urgent research is needed to identify which patients with mild TBI are at risk for incomplete recovery.

The selection of patients for CT is an important triage decision in mild TBI since it allows early identification of lesions that can trigger hospital admission or life-saving surgery. Current decision making for deciding on CT is inefficient, with 90–95% of scanned patients showing no intracranial injury but being subjected to radiation risks. InTBIR studies have shown that measurement of blood-based biomarkers adds value to previously proposed clinical decision rules, holding the potential to improve efficiency while reducing radiation exposure. Increased concentrations of biomarkers in the blood of patients with a normal presentation CT scan suggest structural brain damage, which is seen on MR scanning in up to 30% of patients with mild TBI. Advanced MRI, including diffusion tensor imaging and volumetric analyses, can identify additional injuries not detectable by visual inspection of standard clinical MR images. Thus, the absence of CT abnormalities does not exclude structural damage—an observation relevant to litigation procedures, to management of mild TBI, and when CT scans are insufficient to explain the severity of the clinical condition.

Although blood-based protein biomarkers have been shown to have important roles in the evaluation of TBI, most available assays are for research use only. To date, there is only one vendor of such assays with regulatory clearance in Europe and the USA with an indication to rule out the need for CT imaging for patients with suspected TBI. Regulatory clearance is provided for a combination of biomarkers, although evidence is accumulating that a single biomarker can perform as well as a combination. Additional biomarkers and more clinical-use platforms are on the horizon, but cross-platform harmonisation of results is needed. Health-care efficiency would benefit from diversity in providers.

In the intensive care setting, automated analysis of blood pressure and intracranial pressure with calculation of derived parameters can help individualise management of TBI. Interest in the identification of subgroups of patients who might benefit more from some specific therapeutic approaches than others represents a welcome shift towards precision medicine. Comparative-effectiveness research to identify best practice has delivered on expectations for providing evidence in support of best practices, both in adult and paediatric patients with TBI.

Progress has also been made in improving outcome assessment after TBI. Key instruments have been translated into up to 20 languages and linguistically validated, and are now internationally available for clinical and research use. TBI affects multiple domains of functioning, and outcomes are affected by personal characteristics and life-course events, consistent with a multifactorial bio-psycho-socio-ecological model of TBI, as presented in the US National Academies of Sciences, Engineering, and Medicine (NASEM) 2022 report. Multidimensional assessment is desirable and might be best based on measurement of global functional impairment. More work is required to develop and implement recommendations for multidimensional assessment. Prediction of outcome is relevant to patients and their families, and can facilitate the benchmarking of quality of care. InTBIR studies have identified new building blocks (eg, blood biomarkers and quantitative CT analysis) to refine existing prognostic models. Further improvement in prognostication could come from MRI, genetics, and the integration of dynamic changes in patient status after presentation.

Neurotrauma researchers traditionally seek translation of their research findings through publications, clinical guidelines, and industry collaborations. However, to effectively impact clinical care and outcome, interactions are also needed with research funders, regulators, and policy makers, and partnership with patient organisations. Such interactions are increasingly taking place, with exemplars including interactions with the All Party Parliamentary Group on Acquired Brain Injury in the UK, the production of the NASEM report in the USA, and interactions with the US Food and Drug Administration. More interactions should be encouraged, and future discussions with regulators should include debates around consent from patients with acute mental incapacity and data sharing. Data sharing is strongly advocated by funding agencies. From January 2023, the US National Institutes of Health will require upload of research data into public repositories, but the EU requires data controllers to safeguard data security and privacy regulation. The tension between open data-sharing and adherence to privacy regulation could be resolved by cross-dataset analyses on federated platforms, with the data remaining at their original safe location. Tools already exist for conventional statistical analyses on federated platforms, however federated machine learning requires further development. Support for further development of federated platforms, and neuroinformatics more generally, should be a priority.

This update to the 2017 Commission presents new insights and challenges across a range of topics around TBI: epidemiology and prevention (section 1 ); system of care (section 2 ); clinical management (section 3 ); characterisation of TBI (section 4 ); outcome assessment (section 5 ); prognosis (Section 6 ); and new directions for acquiring and implementing evidence (section 7 ). Table 1 summarises key messages from this Commission and proposes recommendations for the way forward to advance research and clinical management of TBI.

Value of Nonpharmacological Interventions for People With an Acquired Brain Injury: A Systematic Review of Economic Evaluations

OBJECTIVES

Acquired brain injury (ABI) has long-lasting effects, and patients and their families require continued care and support, often for the rest of their lives. For many individuals living with an ABI disorder, nonpharmacological rehabilitation treatment care has become increasingly important care component and relevant for informed healthcare decision making. Our study aimed to appraise economic evidence on the cost-effectiveness of nonpharmacological interventions for individuals living with an ABI.

METHODS

This systematic review was registered in PROSPERO (CRD42020187469), and a protocol article was subject to peer review. Searches were conducted across several databases for articles published from inception to 2021. Study quality was assessed according the Consolidated Health Economic Evaluation Reporting Standards checklist and Population, Intervention, Control, and Outcomes criteria.

RESULTS

Of the 3772 articles reviewed 41 publications met the inclusion criteria. There was a considerable heterogeneity in methodological approaches, target populations, study time frames, and perspectives and comparators used. Keeping these issues in mind, we find that 4 multidisciplinary interventions studies concluded that fast-track specialized services were cheaper and more cost-effective than usual care, with cost savings ranging from £253 to £6063. In 3 neuropsychological studies, findings suggested that meditated therapy was more effective and saved money than usual care. In 4 early supported discharge studies, interventions were dominant over usual care, with cost savings ranging from £142 to £1760.

CONCLUSIONS

The cost-effectiveness evidence of different nonpharmacological rehabilitation treatments is scant. More robust evidence is needed to determine the value of these and other interventions across the ABI care pathway.

A neurobehavioral therapy approach to the rehabilitation and support of persons with brain injury: Practice-based evidence from a UK charitable rehabilitation provider

Background

The treatment and rehabilitation for people with acquired brain injury is continually evolving, with increasing recognition of the importance of approaches that adopt a multi-disciplinary biopsychosocial perspective focused on improving adjustment, social participation, and wellbeing. However, there is significant variability as to how such approaches are delivered, across the various stages of recovery, rehabilitation settings, and within different healthcare systems.

Objective

This paper had three aims. The first was to describe the neurobehavioral therapy (NBT) approach to brain injury rehabilitation adopted in our charitable organization. The second aim was to report how the NBT approach evolved in response to changes in referral patterns, and patient needs within a broader, longer-term clinical pathway. The third aim was to assess the effectiveness of the NBT approach by analyzing outcome data.

Methods

Retrospective analyses of standardized outcome data were completed to investigate the effectiveness of our approach. Case vignettes are provided to illustrate the key components of the approach.

Results

Outcome data suggested that the approach is effective in delivering positive outcomes for patients. Furthermore, the data show differences in presentation between three clinical streams (restoration, compensation, and scaffolding) within the NBT approach.

Conclusions

This paper describes the adaption of the ‘traditional' neurobehavioral approach to brain injury rehabilitation into a model of delivery that can benefit a more diverse range of people living with the heterogenous and long-term consequences of brain injury.

Neurorehabilitation for people with disorders of consciousness: an international survey of health-care structures and access to treatment, (Part 1)

AIMS

The provision of rehabilitation services for people with disorders of consciousness (DoC) may vary due to geographical, financial, and political factors. The extent of this variability and the implementation of treatment standards across countries is unknown. This study explored international neurorehabilitation systems for people with DoC.

METHODS

An online survey (SurveyMonkey®) was disseminated to all members of the International Brain Injury Association (IBIA) DoC Special Interest Group (SIG) examining existing rehabilitation systems and access to them.

RESULTS

Respondents (n = 35) were from 14 countries. Specialized neurorehabilitation was available with varying degrees of access and duration. Commencement of specialized neurorehabilitation averaged 3-4 weeks for traumatic brain injury (TBI) and 5-8 weeks for non-traumatic brain injury (nTBI) etiologies. Length of stay in inpatient rehabilitation was 1-3 months for TBI and 4-6 months for nTBI. There were major differences in access to services and funding across countries. The majority of respondents felt there were not enough resources in place to provide appropriate neurorehabilitation.

CONCLUSIONS

There exists inter-country differences for DoC neurorehabilitation after severe acquired brain injury. Further work is needed to implement DoC treatment standards at an international level.

CONNECT: A pragmatic clinical trial testing a remotely provided linkage to service coordination after hospitalization for TBI

OBJECTIVE

To test whether a complex behavioral intervention delivered remotely to connect individuals to clinical resources after hospitalization for TBI improved their quality of life.

DESIGN/METHODS

Community-based randomized pragmatic clinical trial. Main measures TBI-QOL, Activity Measure for Post-Acute Care (AM-PAC), Clinical Satisfaction and Competency Rating Scale.

RESULTS

332 individuals ≥18 years-old hospitalized for TBI in four upper Midwest states were randomized to Remote (n = 166) and Usual Care (n = 166) groups. The groups were equivalent and representative of their state population's racial and ethnic composition, age, and proportion living in rural communities. There were no significant differences within or between experimental groups over the study period in TBI-QOL t-scores. There was a significant improvement in AM-PAC Daily Activities within the Remote group and a significant between-group improvement in clinical satisfaction for the Remote group.

CONCLUSION

Enrolling a representative, regional community-based sample of individuals with TBI can be successful, and delivering a customized complex behavioral intervention remotely is feasible. The overall lack of intervention effectiveness was likely due to enrolling individuals without pre-identified clinical needs, initiating intervention after the immediate post-acute phase when needs are often highest, inability to provide direct clinical care remotely, and potential lack of outcome measure responsiveness in our sample.

Cost-effectiveness analysis of combined cognitive and vocational rehabilitation in patients with mild-to-moderate TBI: results from a randomized controlled trial

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.

Implementation of early rehabilitation for critically ill children in China: A survey and narrative review of the literature

INTRODUCTION

The focus of this survey was to understand the current status of implementation of early rehabilitation for critically ill children in China. We also reviewed the available literature on this topic for further insights to inform its future development.

MATERIALS AND METHODS

We used a cross-sectional study design to survey tertiary hospitals nationwide. Questionnaires were distributed via the social media platform "WeChat Questionnaire Star" within the framework of the Rehabilitation Group of the Pediatrics Branch of the Chinese Medical Association. A narrative literature review on the implementation of the early rehabilitation for critically ill pediatric and/or adult patients was carried out.

RESULTS

A total of 202 valid questionnaires were received. About half (n = 105, 52.0%) of respondent hospitals reported that they implement early rehabilitation for critically ill children. Among these 105 hospitals, 28 implemented a continuous chain of early rehabilitation. A total of 24 hospitals had set up permanent specialized centralized early rehabilitation units for critically ill children.

IMPLICATIONS AND FUTURE DIRECTIONS

Early rehabilitation for critically ill children is not widely available in China and only a minority of hospitals implement a continuous chain of early rehabilitation. To improve this undesirable situation, we suggest creating a two-level integrated system comprising centralized early rehabilitation units and surrounding early rehabilitation networks within a region.

Value and Cost Savings From Access to Multi-disciplinary Rehabilitation Services After Severe Acquired Brain Injury

Acquired brain injury (ABI) is a major global public health problem and source of disability. A major contributor to disability after severe ABI is limited access to multidisciplinary rehabilitation, despite evidence of sustained functional gains, improved quality of life, increased return-to-work, and reduced need for long-term care. A societal model of value in rehabilitation matches patient and family expectations of outcomes and system expectations of value for money. A policy analysis of seven studies (2009-2019) exploring outcomes and cost-savings from access to multi-disciplinary rehabilitation identified average lifetime savings of $1.50M per person, with costs recouped within 18 months. Recommendations: Increase access to multi-disciplinary rehabilitation following severe ABI; strengthen prevention focus; increase access to case management; support return-to-work; and systematically collect outcome and cost data.

In the Aftermath of Acute Hospitalization for Traumatic Brain Injury: Factors Associated with the Direct Pathway into Specialized Rehabilitation

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.

Predictors for 30-Day Readmissions After Traumatic Brain Injury

OBJECTIVE

To examine predictors for 30-day readmission post-onset of traumatic brain injury (TBI) after initial trauma hospitalization.

DESIGN

Retrospective cohort.

PARTICIPANTS

In total, 5284 patients with an acute TBI admitted from January 1, 2006, through December 31, 2015.

METHODS

Demographic and clinical data after initial TBI onset were extracted from the local trauma registry and matched with the Dallas-Fort Worth Hospital Council registry. Multiple logistic regression analysis was used to determine factors significantly associated with 30-day readmission. Top diagnosis codes for 30-day readmission were also described.

RESULTS

Patients were primarily male (64.6%), non-Hispanic White (47.6%), uninsured (35.4%), and aged 46.1 ± 23.3 years. In total, 448 patients (8.5%) had a 30-day readmission. Median cumulative charges for each readmitted subject was $34 313. Factors significantly associated with 30-day readmission were falling as the cause of injury, having increased Charlson Comorbidity Index and Injury Severity Score, and discharging to a skilled nursing facility or long-term acute care. Being uninsured was associated with decreased odds of a 30-day readmission. Top diagnosis codes among the readmission visits included cardiac codes (57.7%), fluid and acid-base disorders (54.8%), and hypertension (50.1%).

CONCLUSION

These data highlight those at risk for 30-day readmission across a diverse population of TBI at a large medical center. Interventions such as health literacy education or patient navigation may help mitigate 30-day readmission for at-risk patients.

Heterogeneity Is a Hallmark of Traumatic Brain Injury, Not a Limitation: A New Perspective on Study Design in Rehabilitation Research

Purpose In both basic science and intervention research in traumatic brain injury (TBI), heterogeneity in the patient population is frequently cited as a limitation and is often interpreted as a factor reducing certainty in the generalizability of research findings and as a source of conflicting findings across studies. Historically, much of TBI research in rehabilitation and cognition has relied upon case-control studies, with small to modest sample sizes. In this context, heterogeneity is indeed a significant limitation. Here, however, we argue that heterogeneity in patient profiles is a hallmark characteristic of TBI and therefore cannot be avoided or ignored. We argue that this inherent heterogeneity must be acknowledged and accounted for prior to study design. Fortunately, advances in statistical methods and computing power allow researchers to leverage heterogeneity, rather than be constrained by it. Method In this article, we review sources of heterogeneity that contribute to challenges in TBI research, highlight methodological advances in statistical analysis and in other fields with high degrees of heterogeneity (e.g., psychiatry) that may be fruitfully applied to decomposing heterogeneity in TBI, and offer an example from our research group incorporating this approach. Conclusion Only by adopting new methodological approaches can we advance the science of rehabilitation following TBI in ways that will impact clinical practice and inform decision making, allowing us to understand and respond to the range of individual differences that are a hallmark in this population.

Rehabilitation Needs, Service Provision, and Costs in the First Year Following Traumatic Injuries: Protocol for a Prospective Cohort Study

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.

Development of the traumatic brain injury Rehabilitation Needs Survey: a Veterans Affairs TBI Model Systems study

PURPOSE

To describe the development of the Rehabilitation Needs Survey (RNS) for persons in the chronic phase of traumatic brain injury (TBI) recovery.

MATERIALS AND METHODS

RNS items were generated following a literature review (January - March 2015) on the topic of rehabilitation needs and revised via consensus from an expert panel of TBI clinicians and researchers. The RNS was added to the VA TBI Model Systems longitudinal study; data collection occurred between 2015-2019. Needs were classified as current (if endorsed) or absent; if current, needs were classified as unmet if no help was received. Need frequency and association with rehabilitation outcomes were presented.

RESULTS

Eight studies examined rehabilitation needs and formed the initial item pool of 42 needs. This was reduced to form the 21-item RNS which was administered at year 1 (n = 260) and year 2 (n = 297) post-TBI. Number of needs endorsed was 8-9, and number of unmet needs was 1-2, on average. Number of needs was correlated with functional status, neurobehavioral symptoms, and mental health symptoms (p < 0.05) suggesting support for convergent validity of the RNS.

CONCLUSION

The RNS is a new measure of rehabilitation needs following TBI. Further investigation into its psychometrics and clinical utility is recommended.Implications for rehabilitationVeterans and Service Members with traumatic brain injury across the severity spectrum have ongoing rehabilitation needs during the chronic phase of recovery.The Rehabilitation Needs Survey is a standardized measure of rehabilitation needs following traumatic brain injury.Identification of unmet rehabilitation needs is important for raising awareness of service gaps and providing justification for resource allocation.

Unmet Rehabilitation Needs after Traumatic Brain Injury across Europe: Results from the CENTER-TBI Study

This study aims to assess rehabilitation needs and provision of rehabilitation services for individuals with moderate-to-severe disability and investigate factors influencing the probability of receiving rehabilitation within six months after traumatic brain injury (TBI). Overall, the analyses included 1206 individuals enrolled in the CENTER-TBI study with severe-to-moderate disability. Impairments in five outcome domains (daily life activities, physical, cognition, speech/language, and psychological) and the use of respective rehabilitation services (occupational therapy, physiotherapy, cognitive and speech therapies, and psychological counselling) were recorded. Sociodemographic and injury-related factors were used to investigate the probability of receiving rehabilitation. Physiotherapy was the most frequently provided rehabilitation service, followed by speech and occupational therapy. Psychological counselling was the least frequently accessed service. The probability of receiving a rehabilitative intervention increased for individuals with greater brain injury severity (odds ratio (OR) 1.75, CI 95%: 1.27–2.42), physical (OR 1.92, CI 95%: 1.21–3.05) and cognitive problems (OR 4.00, CI 95%: 2.34–6.83) but decreased for individuals reporting psychological problems (OR 0.57, CI 95%: 1.21–3.05). The study results emphasize the need for more extensive prescription of rehabilitation services for individuals with disability. Moreover, targeted rehabilitation programs, which aim to improve outcomes, should specifically involve psychological services to meet the needs of individuals recovering from TBI.

Effect of Early Interdisciplinary Rehabilitation for Trauma Patients: A Systematic Review

Objective

To perform a systematic review to assess the current scientific evidence concerning the effect of EIR for trauma patients with or without an associated traumatic brain injury.

Data Source

We performed a systematic search of several electronic (Ovid MEDLINE, Embase, Cochrane Library Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health, and SveMed+) and 2 clinical trial registers (clinicaltrials.gov and International Clinical Trials Registry Platform). In addition, we handsearched reference lists from relevant studies.

Data Extraction

Two review authors independently identified studies that were eligible for inclusion. The primary outcome measures were functional-related outcomes and return to work. The secondary outcome measures were length of stay in hospital, number of days on respirator, complication rate, physical and mental health measures, quality of life, and socioeconomic costs.

Data Synthesis

Four studies with a total number of 409 subjects, all with traumatic brain–associated injuries, were included in this review. The included trials varied considerably in study design, inclusion and exclusion criteria, and had small numbers of participants. All studies were judged to have at least 1 high risk of bias. We found the quality of evidence, for both our primary and secondary outcomes, low.

Conclusions

No studies that matched our inclusion criteria for EIR for trauma patients without traumatic brain injuries could be found. For traumatic brain injuries, there are a limited number of studies demonstrating that EIR has a positive effect on functional outcomes and socioeconomic costs. This review highlights the need for further research in trauma care regarding early phase interdisciplinary rehabilitation.

Association of Medicaid Expansion With Access to Rehabilitative Care in Adult Trauma Patients

Importance

Trauma is a leading cause of death and disability for patients of all ages, many of whom are also among the most likely to be uninsured. Passage of the Patient Protection and Affordable Care Act was intended to improve access to care through improvements in insurance. However, despite nationally reported changes in the payer mix of patients, the extent of the law's impact on insurance coverage among trauma patients is unknown, as is its success in improving trauma outcomes and promoting increased access to rehabilitation.

Objective

To use rigorous quasi-experimental regression techniques to assess the extent of changes in insurance coverage, outcomes, and discharge to rehabilitation among adult trauma patients before and after Medicaid expansion and implementation of the remainder of the Patient Protection and Affordable Care Act.

Design, Setting, and Participants

Quasi-experimental, difference-in-difference analysis assessed adult trauma patients aged 19 to 64 years in 5 Medicaid expansion (Colorado, Illinois, Minnesota, New Jersey, and New Mexico) and 4 nonexpansion (Florida, Nebraska, North Carolina, and Texas) states.

Interventions/Exposure

Policy implementation in January 2014.

Main Outcomes and Measures

Changes in insurance coverage, outcomes (mortality, morbidity, failure to rescue, and length of stay), and discharge to rehabilitation.

Results

A total of 283 878 patients from Medicaid expansion states and 285 851 patients from nonexpansion states were included (mean age [SD], 41.9 [14.1] years; 206 698 [36.3%] women). Adults with injuries in expansion states experienced a 13.7 percentage point decline in uninsured individuals (95% CI, 14.1-13.3; baseline: 22.7%) after Medicaid expansion compared with nonexpansion states. This coincided with a 7.4 percentage point increase in discharge to rehabilitation (95% CI, 7.0-7.8; baseline: 14.7%) that persisted across inpatient rehabilitation facilities (4.5 percentage points), home health agencies (2.9 percentage points), and skilled nursing facilities (1.0 percentage points). There was also a 2.6 percentage point drop in failure to rescue and a 0.84-day increase in average length of stay. Rehabilitation changes were most pronounced among patients eligible for rehabilitation coverage under the 2-midnight (8.4 percentage points) and 60% (10.2 percentage points) Medicaid payment rules. Medicaid expansion increased rehabilitation access for patients with the most severe injuries and conditions requiring postdischarge care (eg, pelvic fracture). It mitigated race/ethnicity-, age-, and sex-based disparities in which patients use rehabilitation.

Conclusions and relevance

This multistate assessment demonstrated significant changes in insurance coverage and discharge to rehabilitation among adult trauma patients that were greater in Medicaid expansion than nonexpansion states. By targeting subgroups of the trauma population most likely to be uninsured, rehabilitation gains associated with Medicaid have the potential to improve survival and functional outcomes for more than 60 000 additional adult trauma patients nationally in expansion states.

Minimum Competency Recommendations for Programs That Provide Rehabilitation Services for Persons With Disorders of Consciousness: A Position Statement of the American Congress of Rehabilitation Medicine and the National Institute on Disability, Independent Living and Rehabilitation Research Traumatic Brain Injury Model Systems

Persons who have disorders of consciousness (DoC) require care from multidisciplinary teams with specialized training and expertise in management of the complex needs of this clinical population. The recent promulgation of practice guidelines for patients with prolonged DoC by the American Academy of Neurology, American Congress of Rehabilitation Medicine (ACRM), and National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) represents a major advance in the development of care standards in this area of brain injury rehabilitation. Implementation of these practice guidelines requires explication of the minimum competencies of clinical programs providing services to persons who have DoC. The Brain Injury Interdisciplinary Special Interest Group of the ACRM, in collaboration with the Disorders of Consciousness Special Interest Group of the NIDILRR-Traumatic Brain Injury Model Systems convened a multidisciplinary panel of experts to address this need through the present position statement. Content area-specific workgroups reviewed relevant peer-reviewed literature and drafted recommendations which were then evaluated by the expert panel using a modified Delphi voting process. The process yielded 21 recommendations on the structure and process of essential services required for effective DoC-focused rehabilitation, organized into 4 categories: diagnostic and prognostic assessment (4 recommendations), treatment (11 recommendations), transitioning care/long-term care needs (5 recommendations), and management of ethical issues (1 recommendation). With few exceptions, these recommendations focus on infrastructure requirements and operating procedures for the provision of DoC-focused neurorehabilitation services across subacute and postacute settings.

Demographics of traumatic brain injury and outcomes of continuous chain of early rehabilitation in Singapore

Background:

Evidence shows that early initiation of a continuous chain of rehabilitation is associated with better functional outcomes in traumatic brain injured patients. The Department of Rehabilitation Medicine initiated early screening and review of patients with all traumatic brain injury (TBI) severity within 72 hours of acute admission, followed by direct transfer of suitable patients to acute inpatient rehabilitation (AIR).

Objectives:

This study aim to document the demographics and clinical characteristics of all TBI patients admitted to the local acute hospital; determine the characteristics of patients with TBI who are directly transferred to AIR following early screening and review; and determine clinical predictors affecting functional outcomes of patients of all TBI severity.

Methods:

A total of 491 patients were screened and reviewed; 116 patients were directly transferred to AIR.

Results:

The median age of the screened cohort was 67.0 years (interquartile range 50.0–77.0 years). Falls were the leading mechanism of TBI. Infection (odds ratio (OR)=2.95, 95% confidence interval (CI) 1.59–5.49) and neurosurgical intervention (OR=2.18, 95% CI 1.24–3.81) increased the odds of transfer to AIR. The Functional Independence Measure (FIM) gain after receiving AIR was significant ( p<0.001). Increased age, complications, high motor admission FIM (AFIM) and long rehabilitation length of stay (RLOS) were negatively associated with FIM gain and FIM efficiency.

Conclusions:

Our study demonstrated that falls were the leading mechanism of TBI, with the majority of patients being older. Infection and neurosurgical intervention increased the likelihood of transfer to AIR. There was functional improvement after AIR. Age, complications, motor AFIM and RLOS were negatively associated with FIM gain and FIM efficiency. Further local research is warranted to confirm these findings.

What is known about the cost-effectiveness of neuropsychological interventions for individuals with acquired brain injury? A scoping review

The aim of this scoping review was to examine the literature related to economic evaluations of neuropsychological rehabilitation in individuals with acquired brain injury (ABI). PsychINFO, Medline, EMBASE, Cochrane and CINHAL databases were searched in accordance with formal scoping review methodology. Studies were included if published between 1995 and 2019 with a study population of adults aged 18 years or more with any ABI aetiology and there was reported data on resource use, costs or comparative economic analyses as part of an outcome study for rehabilitation interventions. Case studies and trial protocols were excluded. Of 3575 records screened, 30 articles were identified as meeting the inclusion criteria. The majority of studies documented cost savings from provision of various models of multidisciplinary inpatient or outpatient rehabilitation. However, these benefits were estimated without a control group. Eight studies included a cost-effectiveness analysis, and in three, the intervention was reported to be cost-effective compared to the control, one of which saved $9,654 per treated patient. Overall, few eligible studies were identified. Those that included a cost-effectiveness analysis yielded mixed evidence for interventions to be considered cost-effective for ABI. Recommendations for how to incorporate cost-effectiveness analyses into intervention studies are discussed.

In-hospital costs after severe traumatic brain injury: A systematic review and quality assessment

Background

The in-hospital treatment of patients with traumatic brain injury (TBI) is considered to be expensive, especially in patients with severe TBI (s-TBI). To improve future treatment decision-making, resource allocation and research initiatives, this study reviewed the in-hospital costs for patients with s-TBI and the quality of study methodology.

Methods

A systematic search was performed using the following databases: PubMed, MEDLINE, Embase, Web of Science, Cochrane library, CENTRAL, Emcare, PsychINFO, Academic Search Premier and Google Scholar. Articles published before August 2018 reporting in-hospital acute care costs for patients with s-TBI were included. Quality was assessed by using a 19-item checklist based on the CHEERS statement.

Results

Twenty-five out of 2372 articles were included. In-hospital costs per patient were generally high and ranged from $2,130 to $401,808. Variation between study results was primarily caused by methodological heterogeneity and variable patient and treatment characteristics. The quality assessment showed variable study quality with a mean total score of 71% (range 48% - 96%). Especially items concerning cost data scored poorly (49%) because data source, cost calculation methodology and outcome reporting were regularly unmentioned or inadequately reported.

Conclusions

Healthcare consumption and in-hospital costs for patients with s-TBI were high and varied widely between studies. Costs were primarily driven by the length of stay and surgical intervention and increased with higher TBI severity. However, drawing firm conclusions on the actual in-hospital costs of patients sustaining s-TBI was complicated due to variation and inadequate quality of the included studies. Future economic evaluations should focus on the long-term cost-effectiveness of treatment strategies and use guideline recommendations and common data elements to improve study quality.

Bone Marrow Derived Extracellular Vesicles Activate Osteoclast Differentiation in Traumatic Brain Injury Induced Bone Loss

Traumatic brain injury (TBI) is a major source of worldwide morbidity and mortality. Patients suffering from TBI exhibit a higher susceptibility to bone loss and an increased rate of bone fractures; however, the underlying mechanisms remain poorly defined. Herein, we observed significantly lower bone quality and elevated levels of inflammation in bone and bone marrow niche after controlled cortical impact-induced TBI in in vivo CD-1 mice. Further, we identified dysregulated NF-κB signaling, an established mediator of osteoclast differentiation and bone loss, within the bone marrow niche of TBI mice. Ex vivo studies revealed increased osteoclast differentiation in bone marrow-derived cells from TBI mice, as compared to sham injured mice. We also found bone marrow derived extracellular vesicles (EVs) from TBI mice enhanced the colony forming ability and osteoclast differentiation efficacy and activated NF-κB signaling genes in bone marrow-derived cells. Additionally, we showed that miRNA-1224 up-regulated in bone marrow-derived EVs cargo of TBI. Taken together, we provide evidence that TBI-induced inflammatory stress on bone and the bone marrow niche may activate NF-κB leading to accelerated bone loss. Targeted inhibition of these signaling pathways may reverse TBI-induced bone loss and reduce fracture rates.

Family members' experience with in-hospital health care after severe traumatic brain injury: a national multicentre study

BACKGROUND

Family member's experience and satisfaction of health care in the acute care and in-patient rehabilitation are important indicators of the quality of health care services provided to patients with severe traumatic brain injury (TBI). The objective was to assess family members' experience of the health care provided in-hospital to patients with severe TBI, to relate experiences to family member and patient demographics, patients' function and rehabilitation pathways.

METHODS

Prospective national multicentre study of 122 family members of patients with severe TBI. The family experience of care questionnaire in severe traumatic brain injury (FECQ-TBI) was applied. Independent sample t-tests or analysis of variance (ANOVA) were used to compare the means between 2 or more groups. Paired samples t-tests were used to investigate differences between experience in the acute and rehabilitation phases.

RESULTS

Best family members` experience were found regarding information during the acute phase, poorest scores were related to discharge. A significantly better care experience was reported in the acute phase compared with the rehabilitation phase (p < 0.05). Worst family members` experience was related to information about consequences of the injury. Patient's dependency level (p < 0.05) and transferral to non-specialized rehabilitation were related to a worse family members` experience (p < 0.01).

CONCLUSIONS

This study underscores the need of better information to family members of patients with severe TBI in the rehabilitation as well as the discharge phase. The results may be important to improve the services provided to family members and individuals with severe TBI.

Practitioners' opinions on traumatic brain injury care pathways in Finland and France: different organizations, common issues

OBJECTIVE

In traumatic brain injury (TBI), differences in health-care contexts have profound effects on care pathways. Objectives were to compare TBI pathways of care and practitioners' views on quality of care issues in two large European areas: Varsinais-Suomi, Finland and Ile-de-France, France.

METHODS

Thematic analysis of semi-structured interviews was conducted with TBI practitioners (n = 10) from all stages of TBI care. Interviews addressed organization and financing of care, decision-making on care transitions, and perceived issues. The structure-process-outcome model of Donabedian was used to classify findings related to quality of care issues.

RESULTS

Main differences in organization of care pathways for people with TBI were related to financing modalities, number of pathway alternatives, inpatient versus outpatient rehabilitation, and indirect versus direct referrals to rehabilitation. Similar categories of issues were raised in the two settings. Issues in structures involved availability of services, financial access, and heterogeneity of expertise. Issues in processes involved diagnosis and follow-up, training regarding cognitive impairments, decision-making for referrals, transition delays, and care pathways of very severely affected patients.

CONCLUSIONS

These findings provide clues to address care pathways in further comparative studies. Determinants of care pathway quality could be classified as direct or indirect, binding or adaptive organizational factors.

Combined cognitive and vocational interventions after mild to moderate traumatic brain injury: study protocol for a randomized controlled trial

Background

A considerable proportion of patients with mild to moderate traumatic brain injury (TBI) experience long-lasting somatic, cognitive, and emotional symptoms that may hamper their capacity to return to work (RTW). Although several studies have described medical, psychological, and work-related factors that predict RTW after TBI, well-controlled intervention studies regarding RTW are scarce. Furthermore, there has traditionally been weak collaboration among health-related rehabilitation services, the labor and welfare sector, and workplaces.

Methods/design

This study protocol describes an innovative randomized controlled trial in which we will explore the effect of combining manualized cognitive rehabilitation (Compensatory Cognitive Training [CCT]) and supported employment (SE) on RTW and related outcomes for patients with mild to moderate TBI in real-life competitive work settings. The study will be carried out in the southeastern region of Norway and thereby be performed within the Norwegian welfare system. Patients aged 18–60 years with mild to moderate TBI who are employed in a minimum 50% position at the time of injury and sick-listed 50% or more for postconcussive symptoms 2 months postinjury will be included in the study. A comprehensive assessment of neurocognitive function, self-reported symptoms, emotional distress, coping style, and quality of life will be performed at baseline, immediately after CCT (3 months after inclusion), following the end of SE (6 months after inclusion), and 12 months following study inclusion. The primary outcome measures are the proportion of participants who have returned to work at 12-month follow-up and length of time until RTW, in addition to work stability as well as work productivity over the first year following the intervention. Secondary outcomes include changes in self-reported symptoms, emotional and cognitive function, and quality of life. Additionally, a qualitative RTW process evaluation focused on organizational challenges at the workplace will be performed.

Discussion

The proposed study will combine cognitive and vocational rehabilitation and explore the efficacy of increased cross-sectoral collaboration between specialized health care services and the labor and welfare system. If the intervention proves effective, the project will describe the cost-effectiveness and utility of the program and thereby provide important information for policy makers. In addition, knowledge about the RTW process for persons with TBI and their workplaces will be provided.

Integrated Health Care Management of Moderate to Severe TBI in Older Patients-A Narrative Review

PURPOSE OF REVIEW

Traumatic brain injuries are common, especially within the elderly population, which is typically defined as age 65 and older. This narrative review aims at summarizing and critically evaluating important aspects of their health care management in covering the entire pathway from prehospital care to rehabilitation and beyond.

RECENT FINDINGS

The number of older patients with traumatic brain injury (TBI) is increasing, and there seem to be differences in all aspects of care along their pathway when compared to younger patients. Despite a higher mortality and a generally less favorable outcome, the current literature shows that older TBI patients have the potential to make significant improvements over time. More research is needed to evaluate the most efficient and integrated clinical pathway from prehospital interventions to rehabilitation as well as the optimal treatment of older TBI patients. Most importantly, they should not be denied access to specific treatments and therapies only based on age.

The rehabilitation research matrix: producing knowledge at micro, meso, and macro levels

PURPOSE

EU policy documents and health scholars point out that in order to understand the complexity of modern health systems, as well as to devise appropriate policy responses, considering micro, meso, and macro levels is indispensable. This article aims to develop an analytical framework for how rehabilitation as an interdisciplinary field can be framed in such a three-level framework.

METHODS

This is a conceptual paper based on recent contributions to the development of a theory of rehabilitation. The paper applies sociological theory to build an analytical framework for a holistic understanding of rehabilitation.

RESULTS

Three groups of agents in the field of rehabilitation are identified: individuals with disabilities, professionals, and governmental authorities. The paper systematizes how these agents are positioned and act at micro, meso, and macro levels. In the intersection between the three levels of society and the three groups of actors, a nine-cell table emerges. In the cells of the table, key examples of important social processes to study in the field of disability and rehabilitation are identified. At the micro level, individuals experience a daily life relevant to rehabilitation, professionals ask what works in therapy, and policy authorities promote a strong work ethic. At the meso level, individuals with disabilities act as service user groups, professionals develop organizational designs and the policy authorities ask for cost-effective services. At the macro level, organizations representing people with disabilities lobby, professionals negotiate authorization issues, and the policymaking authorities must identify what can count as just distribution of services. The nine cells of the table are elaborated on by presenting relevant current studies exemplifying each cell.

CONCLUSION

To systematize societal levels and agents involved is to enhance the understanding of rehabilitation as an interdisciplinary field of research. Implications for rehabilitation Rehabilitation practice and research must relate to different levels of society and identify different social agents. Service users are not only individuals receiving therapy, but also organized agents influencing the organization of rehabilitation services as well as priorities made at the level of policy development. Both the results produced by health professionals doing a clinical trial and political scientists studying rehabilitation policy disputes will improve when placed in a wide frame of knowledge production.

Cost effectiveness of inpatient rehabilitation in patients with brain injury

Rehabilitation following acquired brain injury improves health outcomes, reduces disability, and improves quality of life. We assessed the cost effectiveness of inpatient rehabilitation after brain injury in individuals with brain injury admitted to the Irish national tertiary specialist rehabilitation centre in 2011. Patients' score on the Disability Rating Scale (DRS) was recorded on admission and at discharge after intensive inpatient rehabilitation. Cost savings attributed to the rehabilitation programme were calculated as the difference between direct care costs on admission and discharge. Direct costs of care were calculated as the weekly cost of the care-assistant hours required to care for patients on the basis of their level of disability or daily nursing-home bed cost when this was required. Of 63 patients, complete DRS information for admission and discharge was available for 41. DRS scores, and therefore average levels of functioning, differed significantly at admission (2.3, between mildly and moderately dependent) and discharge (1.1, independent in special environments, p<0.01). Average weekly care costs fell from €629 to €242, with costs recouped within 30 months. Thus, substantial savings result from inpatient rehabilitation, and these savings could have been greater had we considered also the economic benefit of enabling patients to return to employment.

Multi-disciplinary rehabilitation for acquired brain injury in adults of working age

BACKGROUND

Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, in which older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults has not been established, perhaps because this scenario presents different methodological challenges in research.

OBJECTIVES

To assess the effects of multi-disciplinary rehabilitation following ABI in adults 16 to 65 years of age.

SEARCH METHODS

We ran the most recent search on 14 September 2015. We searched the Cochrane Injuries Group Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (OvidSP), Web of Science (ISI WOS) databases, clinical trials registers, and we screened reference lists.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation versus routinely available local services or lower levels of intervention; or trials comparing an intervention in different settings, of different intensities or of different timing of onset. Controlled clinical trials were included, provided they met pre-defined methodological criteria.

DATA COLLECTION AND ANALYSIS

Three review authors independently selected trials and rated their methodological quality. A fourth review author would have arbitrated if consensus could not be reached by discussion, but in fact, this did not occur. As in previous versions of this review, we used the method described by Van Tulder 1997 to rate the quality of trials and to perform a 'best evidence' synthesis by attributing levels of evidence on the basis of methodological quality. Risk of bias assessments were performed in parallel using standard Cochrane methodology. However, the Van Tulder system provided a more discriminative evaluation of rehabilitation trials, so we have continued to use it for our primary synthesis of evidence. We subdivided trials in terms of severity of brain injury, setting and type and timing of rehabilitation offered.

MAIN RESULTS

We identified a total of 19 studies involving 3480 people. Twelve studies were of good methodological quality and seven were of lower quality, according to the van Tulder scoring system. Within the subgroup of predominantly mild brain injury, 'strong evidence' suggested that most individuals made a good recovery when appropriate information was provided, without the need for additional specific interventions. For moderate to severe injury, 'strong evidence' showed benefit from formal intervention, and 'limited evidence' indicated that commencing rehabilitation early after injury results in better outcomes. For participants with moderate to severe ABI already in rehabilitation, 'strong evidence' revealed that more intensive programmes are associated with earlier functional gains, and 'moderate evidence' suggested that continued outpatient therapy could help to sustain gains made in early post-acute rehabilitation. The context of multi-disciplinary rehabilitation appears to influence outcomes. 'Strong evidence' supports the use of a milieu-oriented model for patients with severe brain injury, in which comprehensive cognitive rehabilitation takes place in a therapeutic environment and involves a peer group of patients. 'Limited evidence' shows that specialist in-patient rehabilitation and specialist multi-disciplinary community rehabilitation may provide additional functional gains, but studies serve to highlight the particular practical and ethical restraints imposed on randomisation of severely affected individuals for whom no realistic alternatives to specialist intervention are available.

AUTHORS' CONCLUSIONS

Problems following ABI vary. Consequently, different interventions and combinations of interventions are required to meet the needs of patients with different problems. Patients who present acutely to hospital with mild brain injury benefit from follow-up and appropriate information and advice. Those with moderate to severe brain injury benefit from routine follow-up so their needs for rehabilitation can be assessed. Intensive intervention appears to lead to earlier gains, and earlier intervention whilst still in emergency and acute care has been supported by limited evidence. The balance between intensity and cost-effectiveness has yet to be determined. Patients discharged from in-patient rehabilitation benefit from access to out-patient or community-based services appropriate to their needs. Group-based rehabilitation in a therapeutic milieu (where patients undergo neuropsychological rehabilitation in a therapeutic environment with a peer group of individuals facing similar challenges) represents an effective approach for patients requiring neuropsychological rehabilitation following severe brain injury. Not all questions in rehabilitation can be addressed by randomised controlled trials or other experimental approaches. For example, trial-based literature does not tell us which treatments work best for which patients over the long term, and which models of service represent value for money in the context of life-long care. In the future, such questions will need to be considered alongside practice-based evidence gathered from large systematic longitudinal cohort studies conducted in the context of routine clinical practice.

Subacute complications during recovery from severe traumatic brain injury: frequency and associations with outcome

BACKGROUND

Medical complications after severe traumatic brain injury (S-TBI) may delay or prevent transfer to rehabilitation units and impact on long-term outcome.

OBJECTIVE

Mapping of medical complications in the subacute period after S-TBI and the impact of these complications on 1-year outcome to inform healthcare planning and discussion of prognosis with relatives.

SETTING

Prospective multicentre observational study. Recruitment from 6 neurosurgical centres in Sweden and Iceland.

PARTICIPANTS AND ASSESSMENTS

Patients aged 18-65 years with S-TBI and acute Glasgow Coma Scale 3-8, who were admitted to neurointensive care. Assessment of medical complications 3 weeks and 3 months after injury. Follow-up to 1 year. 114 patients recruited with follow-up at 1 year as follows: 100 assessed, 7 dead and 7 dropped out.

OUTCOME MEASURE

Glasgow Outcome Scale Extended.

RESULTS

68 patients had ≥1 complication 3 weeks after injury. 3 weeks after injury, factors associated with unfavourable outcome at 1 year were: tracheostomy, assisted ventilation, on-going infection, epilepsy and nutrition via nasogastric tube or percutaneous endoscopic gastroscopy (PEG) tube (univariate logistic regression analyses). Multivariate analysis demonstrated that tracheostomy and epilepsy retained significance even after incorporating acute injury severity into the model. 3 months after injury, factors associated with unfavourable outcome were tracheostomy and heterotopic ossification (Fisher's test), infection, hydrocephalus, autonomic instability, PEG feeding and weight loss (univariate logistic regression). PEG feeding and weight loss at 3 months were retained in a multivariate model.

CONCLUSIONS

Subacute complications occurred in two-thirds of patients. Presence of a tracheostomy or epilepsy at 3 weeks, and of PEG feeding and weight loss at 3 months, had robust associations with unfavourable outcome that were incompletely explained by acute injury severity.

Assessment and Treatment of Cognition and Communication Skills in Adults With Acquired Brain Injury via Telepractice: A Systematic Review

PURPOSE

This is a systematic review of assessment and treatment of cognitive and communicative abilities of individuals with acquired brain injury via telepractice versus in person. The a priori clinical questions were informed by previous research that highlights the importance of considering any functional implications of outcomes, determining disorder- and setting-specific concerns, and measuring the potential impact of diagnostic accuracy and treatment efficacy data on interpretation of findings.

METHOD

A literature search of multiple databases (e.g., PubMed) was conducted using key words and study inclusion criteria associated with the clinical questions.

RESULTS

Ten group studies were accepted that addressed assessment of motor speech, language, and cognitive impairments; assessment of motor speech and language activity limitations/participation restrictions; and treatment of cognitive impairments and activity limitations/participation restrictions. In most cases, equivalence of outcomes was noted across service delivery methods.

CONCLUSIONS

Limited findings, lack of diagnostic accuracy and treatment efficacy data, and heterogeneity of assessments and interventions precluded robust evaluation of clinical implications for telepractice equivalence and the broader area of telepractice efficacy. Future research is needed that will build upon current knowledge through replication. In addition, further evaluation at the impairment and activity limitation/participation restriction levels is needed.
