Randomized Controlled Trials of Rehabilitation Services in the Post-acute Phase of Moderate and Severe Traumatic Brain Injury - A Systematic Review

Outcomes of Six Specific Types of Post-Hospital Brain Injury Rehabilitation Programs

OBJECTIVE

Evaluate outcomes of intensive posthospital brain injury rehabilitation programs compared to supported living (SL) programs; explore variations in outcome by diagnostic category (traumatic brain injury, stroke, and other acquired brain injury [ABI]) and specific program type.

SETTING

Data were obtained from Residential Neurobehavioral, Residential Neurorehabilitation, Home and Community Neurorehabilitation, Day Treatment, Outpatient Neurorehabilitation, and SL programs serving individuals with ABI.

PARTICIPANTS

A total of 2120 individuals with traumatic brain injury, stroke, or other ABI participated in this study.

MAIN MEASURES

The main measures are sex, age, time since injury, and Mayo-Portland Adaptability Inventory (4th edition; MPAI-4).

DESIGN

Retrospective analyses of demographic variables and MPAI-4 Total, index, and subscale Rasch-derived T-scores on admission and discharge.

RESULTS

Gains on MPAI-4 Total T-scores were significantly greater for the intensive rehabilitation (IR) group in comparison to stable functioning in the SL group ( F = 236.69, P < .001, partial η 2  = .101) while controlling for admission/time 1 scores; similar results were found for MPAI-4 indices and subscales. For the IR cohort, discharge scores differed by diagnostic category after controlling for admission scores for the Total MPAI-4 T-score ( F = 22.65, P < .001, partial η 2  = .025), as well as all indices and subscales. A statistically significant interaction between program type and diagnostic group on discharge MPAI-4 Total T-scores ( F = 2.55, P = .018, partial η 2  = .01) after controlling for admission scores indicated that differing outcomes across diagnoses also varied by program type. Varying significant main effects and interactions were apparent for MPAI-4 indices and subscales with generally small effect sizes.

CONCLUSIONS

Significant gains on MPAI-4 variables across IR program types compared to no change over a comparable period of time for SL programs supports the effectiveness of posthospital brain injury rehabilitation. This finding in the presence of small effect sizes on outcome variables for program type and for significant interactions between program type and diagnostic category suggests that participants generally were appropriately matched to program type and benefited from interventions provided through specific program types.

Proposed categories for reporting of service organization in rehabilitation in clinical trials: a discussion paper

BACKGROUND

The lack of standardized reporting for crucial organizational factors in rehabilitation poses a significant barrier to understanding their impact on patient outcomes in clinical trials and meta-analyses.

AIM

Based on the categories in the International Classification of Service Organization in Rehabilitation (ICSO-R 2.0), we aimed to develop reporting standards specifically for organizational factors in clinical trials.

METHODS

A comprehensive two-step process was conducted. In Step 1, important categories were identified. The identification was based on previous results from a Delphi survey with international stakeholder participation, two systematic literature reviews and results from focus groups with users in Germany, Indonesia and Norway. Step 2 involved the necessary reduction of categories and the proposal of reporting specifications, achieved through two voting rounds among key researchers, stakeholders and users.

RESULTS

The suggested minimum reporting set comprises Context and Setting as well as Quality assurance and management. The Context and Setting is proposed to include whether the intervention is delivered by Hospital, Community or Other service providers. The Mode of delivery is proposed to be specified as Inpatient, Outpatient, In-home, or Tele-rehabilitation. Furthermore, the Level of specialization (Primary/Secondary) and the Phase of service delivery Acute, Subacute or Long-term rehabilitation services should be reported. The Quality assurance and management should be reported as Yes or No, with the option Yes requiring description of the quality assurance applied in the methods section.

CONCLUSIONS

This study proposed a compulsory and standardized reporting of organizational factors in clinical trials to facilitate the generation of scientific evidence regarding effective service provision and delivery in rehabilitation medicine. Authors are encouraged to consider the proposed reporting set to testing, criticism, and modification to enhance its applicability and robustness.

Traumatic Brain Injury

Advances in trauma care have allowed persons with traumatic brain injury to survive at increasingly greater rates. However, they commonly go on to experience complex symptoms including changes in cognitive, emotional, and behavioral functioning that together limit functioning and quality of life. Clinical neuropsychology is uniquely skilled to work together with other rehabilitation professionals, using a patient centered approach, evidence-based treatments, and increasingly using emerging technology while adhering to ethical principles of respect, beneficence, and justice. Doing so will most effectively manage these changes, leading to the best possible quality of life and maximum improvement in functioning.

International classification of functioning, disability and health with long-term consequences of cranio-brain injury

OBJECTIVE

Aim: To describe health status and related functioning of patients with different severity of traumatic brain injury (TBI) in past medical history in Ukraine and determining the feasibility of using the International Classification of Functioning, Disability and Health (ICF) Brief Core Set for TBI.

PATIENTS AND METHODS

Materials and Methods: A total of 102 patients, who were treated in the neurological department of Dnipropetrovsk regional clinical hospital and State Institution ≪Ukrainian State Scientific Research Institute of Medical and Social Problems of Disability of Health Ministry of Ukraine≫, had been examined. Patients were divided into three groups: mild, moderate and severe TBI in past history and evaluated using ICF Brief Core Set for TBI.

RESULTS

Results: Тhe most common problems in the functioning and health of patients in remote period of TBI, along with the influencing factors have been identified in the study. The most frequent categories from ≪Body Functions≫ and ≪Activity and Participation≫ sections in which patients had alterations were: memory functions, emotional functions, sensation of pain, functions of attention, brain structure, complex interpersonal interactions, family relationships. The increase in the amount and severity of disturbances with increasing severity of TBI had been established in all categories, except complex interpersonal interactions and family relationships.

CONCLUSION

Conclusions: Patients of all groups identified the family and close relatives, healthcare service and social welfare services, as the most frequent relieving factors of life activity. The use of the ICF Brief Core Set for assessing the subjects with TBI in past history provides a convenient procedure to standardize and structure functioning description. Information collected by the ICF Brief Core Set may be used for different purposes: clinical assessment, administration of medical services, planning and implementation of rehabilitation and evaluation of results, in scientific research, reports and health care statistics.

Impact of Sociodemographic, Premorbid, and Injury-Related Factors on Patient-Reported Outcome Trajectories after Traumatic Brain Injury (TBI)

Traumatic brain injury (TBI) remains one of the leading causes of death and disability worldwide. To better understand its impact on various outcome domains, this study pursues the following: (1) longitudinal outcome assessments at three, six, and twelve months post-injury; (2) an evaluation of sociodemographic, premorbid, and injury-related factors, and functional recovery contributing to worsening or improving outcomes after TBI. Using patient-reported outcome measures, recuperation trends after TBI were identified by applying Multivariate Latent Class Mixed Models (MLCMM). Instruments were grouped into TBI-specific and generic health-related quality of life (HRQoL; QOLIBRI-OS, SF-12v2), and psychological and post-concussion symptoms (GAD-7, PHQ-9, PCL-5, RPQ). Multinomial logistic regressions were carried out to identify contributing factors. For both outcome sets, the four-class solution provided the best match between goodness of fit indices and meaningful clinical interpretability. Both models revealed similar trajectory classes: stable good health status (HRQoL: n = 1944; symptoms: n = 1963), persistent health impairments (HRQoL: n = 442; symptoms: n = 179), improving health status (HRQoL: n = 83; symptoms: n = 243), and deteriorating health status (HRQoL: n = 86; symptoms: n = 170). Compared to individuals with stable good health status, the other groups were more likely to have a lower functional recovery status at three months after TBI (i.e., the GOSE), psychological problems, and a lower educational attainment. Outcome trajectories after TBI show clearly distinguishable patterns which are reproducible across different measures. Individuals characterized by persistent health impairments and deterioration require special attention and long-term clinical monitoring and therapy.

Predictors of Social Participation Outcome after Traumatic Brain Injury Differ According to Rehabilitation Pathways

Social participation (SP) is one of many objectives in the rehabilitation of patients with traumatic brain injury (TBI). Studies on predictors of SP specific to post-acute universally accessible specialized rehabilitation pathways following TBI are scarce. Our objectives were to: 1) characterize SP, as well as a set of pre-injury, injury-related, and post-injury variables in individuals participating in inpatient-outpatient or outpatient rehabilitation pathways within a universally accessible and organized trauma continuum of care; and 2) examine the ability of pre-injury, injury-related, and post-injury variables in predicting SP outcome after TBI according to rehabilitation path. Participants (N = 372) were adults admitted to an inpatient-outpatient rehabilitation pathway or an outpatient rehabilitation pathway after sustaining a TBI between 2016 and 2020, and for whom Mayo-Portland Adaptability Intentory-4 (MPAI-4) outcomes were prospectively obtained at the start and end of rehabilitation. Additional data was collected from medical files. For both rehabilitation pathways, predicted SP outcome was MPAI-4 Participation score at discharge from outpatient rehabilitation. Multiple regression models investigated the predictive value of each variable for SP outcome, separately for each care pathway. Main findings show that for the inpatient-outpatient sample, three variables (education years, MPAI-4 Ability and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 49% of the variance. For the outpatient sample, five variables (pre-morbid hypertension and mental health diagnosis, total indirect rehabilitation hours received, MPAI-4 Abilities and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 47% of the variance. In conclusion, different pre-morbid and post-injury variables are involved in predicting SP, depending on the rehabilitation path followed. The predictive value of those variables could help clinicians identify patients more likely of showing poorer SP at discharge and who may require additional or different interventions.

A Systematic Review and Meta-Analysis of the Effectiveness of Virtual Reality-Based Rehabilitation Therapy on Reducing the Degree of Pain Experienced by Individuals with Low Back Pain

BACKGROUND

The concept of virtual reality (VR)-based rehabilitation therapy for treating people with low back pain is of growing research interest. However, the effectiveness of such therapy for pain reduction in clinical settings remains controversial.

METHODS

The present study was conducted according to the reporting guidelines presented in the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. We searched the PubMed, Embase, CENTRAL, and ProQuest databases for both published and unpublished papers. The Cochrane risk of bias tool (version 2) was used to evaluate the quality of the selected studies. GRADEprofiler software (version 3.6.4) was used to evaluate the level of evidence. We analyzed the included research results using RevMan software (version 5.4.1).

RESULTS

We included a total of 11 articles in the systematic review and meta-analysis, with a total of 1761 subjects. Having assessed the quality of these studies, the risk of bias was generally low with high heterogeneity. The results revealed a small to medium effect (standardized mean difference = ±0.37, 95% confidence interval: 0.75 to 0) based on evidence of moderate overall quality.

CONCLUSION

There is evidence that treatment using VR improves patients' pain. The effect size was small to medium, with the studies presenting evidence of moderate overall quality. VR-based treatment can reduce pain; therefore, it may help in rehabilitation therapy.

Healthcare services for people with acquired disability in South-East Queensland, Australia: Assessing potential proximity and its association with service obstacles

This study described access potential in South-East Queensland, to healthcare services commonly used by people with acquired disability; and investigated the association between service proximity and perceived service obstacles. First, we described accessibility by conducting a spatial analysis to create maps of potential accessibility to health services in South-East Queensland. Queensland statistical area level 2 (SA2) locations were combined with the residential locations of participants from a longitudinal cohort study involving people with ABI and SCI. The locations of selected health services of interest were identified from Health Direct's National Health Service Directory. Travel times via motor vehicle were modelled with Robust Gaussian Stochastic Process, to smoothly interpolate between the sparse time-to-service observations. Probabilistic predicted values were generated from the model and were used to construct service accessibility maps of South-East Queensland. Disability population data were used to identify SA2s with relatively low service access but a high disability population. Second, we examined perceived service obstacles, by investigating the relationship between potential access to services and perceived service obstacles was examined using data from 63 people with ABI or SCI discharged from the specialist state-wide rehabilitation services, located in South-East Queensland. Obstacles to accessing service in relation to resource availability, transportation and finances were collected three-months after discharge, using the Service Obstacle Scale. Travel times to the closest health service were computed for each individual and were compared to their Service Obstacle Scale responses. Access potential was highly variable, particularly for allied health services. We identified several low-access, high-disability population areas. These hotpots of poor access were generally to the north and west of greater Brisbane. Longer travel times to allied health services were associated with 260% higher odds of agreeing that resource availability was an obstacle to accessing services. Policy makers should be concerned with the hotspots of poor access identified.

•

There was considerable variability in access potential, which was generally greater for allied health than medical specialist services.

•

We highlighted low-access high disability population areas, which were generally in outer suburbia.

•

Poorer potential access to allied health services was associated with resource availability being rated as an service obstacle.

•

We did not find any evidence that proximity to allied health services was associated with transportation or finance obstacles.

Biomarkers of Neuroinflammation in Traumatic Brain Injury

Traumatic brain injury (TBI) is characterized by neuroinflammation and structural damage leading to symptoms and altered brain function. Biomarkers are useful in understanding neuroinflammation and correlations with TBI sequalae. The purpose of this paper is to identify and discuss biomarkers of neuroinflammation used to study TBI and its sequalae. A systematic review was conducted using PubMed, CINAHL, Embase, and Web of Science. A total of 350 articles met criteria; 70 used biomarkers. PRISMA criteria were used for Quality Assessment. Articles included reviews (n = 17), case-control (n = 25), cross-sectional (n = 25) studies, and randomized controlled trials (n = 3). Twenty-seven biomarkers were identified, including inflammasomes, cytokines, neuropeptides, complement complexes, miRNA and exosomes, and glial cell-specific proteins. Biomarkers aid in predicting morbidity and mortality and advance our understanding of neuroinflammation in TBI. This systematic review advances our understanding of the neuroinflammatory response to better enable nurses and clinicians to provide informed care of TBI patients.

Organization of rehabilitation services in randomized controlled trials - which factors influence functional outcome? A systematic review

Objective

To identify factors related to the organization of rehabilitation services that may influence patients’ functional outcome and make recommendations for categories to be used in the reporting of rehabilitation interventions.

Data Sources

A systematic review based on a search in MEDLINE indexed journals (MEDLINE [OVID], Cumulative Index of Nursing and Allied Health Literature, PsycINFO, Cochrane Central Register of Controlled Trials) until June 2019.

Study Selection

In total 8587 candidate randomized controlled trials reporting on organizational factors of multidisciplinary rehabilitation interventions and their associations with functional outcome. An additional 1534 trials were identified from June 2019 to March 2021. Data Extraction: Quality evaluation was conducted by 2 independent researchers. The organizational factors were classified according to the International Classification for Service Organization in Health-related Rehabilitation 2.0.

Data Synthesis

In total 80 articles fulfilled the inclusion criteria. There was a great heterogeneity in the terminology and reporting of service organization across all studies. Aspects of Settings including the Mode of Service Delivery was the most explicitly analyzed organizational category (44 studies). The importance of the integration of rehabilitation in the inpatient services was supported. Furthermore, several studies documented a lack of difference in outcome between outpatient vs inpatient service delivery. Patient Centeredness, Integration of Care, and Time and Intensity factors were also analyzed, but heterogeneity of interventions in these studies prohibited aggregation of results.

Conclusions

Settings and in particular the way the services were delivered to the users influenced functional outcome. Hence, it should be compulsory to include a standardized reporting of aspects of service delivery in clinical trials. We would also advise further standardization in the description of organizational factors in rehabilitation interventions to build knowledge of effective service organization.

Right people, right time? a qualitative study of service access experiences of adults with acquired brain injury following discharge from inpatient rehabilitation

Purpose:

The intention of this paper is to develop the personal concept of appropriate access. We report on the service access experiences and opportunities of adults with an acquired brain injury after leaving inpatient rehabilitation. The benefits of appropriate access underpin standards in early and long-term recovery, though users’ access needs are highly personal.

Methods:

The study used a qualitative design involving 16 semi-structured interviews with Australian adults with an acquired brain injury after discharge from inpatient brain rehabilitation. Data were thematically analysed.

Results:

Three main themes were derived from the analysis. Theme 1 shows that participants valued being steered to services that providers thought appropriate for them early after discharge from inpatient rehabilitation. Theme 2 highlights the tensions between timing and personal recovery and perceived needs. Theme 3 captures participants’ insights into the challenges of gaining access vis-a-vis what the system offers and the enablers of actualising appropriate access.

Conclusion:

The positive experiences of being directed to specialist services early after discharge suggest that continuity of care constitutes appropriateness of access for participants in this study. However, it is also clear that continuity should not displace flexibility in the timing of services, to accord with individuals’ perceived needs. This, in addition to enablement of access opportunities, through funding and transport, are important in maintaining a personalised approach.

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.

Participation Following Inpatient Rehabilitation for Traumatic Disorders of Consciousness: A TBI Model Systems Study

Severe traumatic brain injury (TBI) may result in a disorder of consciousness (DoC) and lead to substantial long-term disability. While level of independence with activities of daily living, especially for persons who recover consciousness during inpatient rehabilitation, generally improves over time, the degree of change in participation remains unknown. We determined level of participation among persons with TBI between 2005 and 2017 who were admitted to inpatient rehabilitation unable to follow commands and subsequently enrolled in the TBI Model Systems National Database. Participation on the Participation Assessment with Recombined Tools-Objective (PART-O) Productivity, Social Relations, and Out and About subscales was evaluated at 1-5 years post-injury. We used a mixed-effects model to longitudinally compare participation between persons who did and did not regain command-following during inpatient rehabilitation. We further explored the level of participation associated with increasing levels of functional independence (FIM). The analysis included 333 persons (229 recovered command-following during rehabilitation, mean age = 35.46 years, 74.9% male). Participation across groups, at all follow-up time points, on all PART-O subscales, was remarkably low (mean range = 0.021-1.91, maximum possible score = 5). Performance was highest on the Social Relations subscale and lowest on the Productivity subscale. Longitudinal analyses revealed no difference in level of participation or change in participation across time for persons who regained command-following during rehabilitation compared to those who did not. While productivity increased over time, social participation did not and participation outside the home increased more for younger than for older persons. Across all three PART-O subscales, FIM Motor scores positively predicted participation. FIM Cognitive scores positively predicted level of participation on the Productivity and Social Relations subscales. Exploratory analyses revealed that even persons who achieved independence on the FIM Motor and Cognitive subscales had low levels of participation across domains and follow-up years. In summary, persons with severe TBI who were admitted to inpatient rehabilitation unable to follow commands were found to be unlikely to participate in productive tasks, social endeavors, or activities outside of the home up to 5 years post-injury, even if functional independence was recovered.
