Outcome prediction in home- and community-based brain injury rehabilitation using the Mayo-Portland Adaptability Inventory

Community-Based Interventions After Acquired Brain Injury-A Systematic Review of Intervention Types and Their Effectiveness

OBJECTIVES

Comprehensive review of existing types and effectiveness of community-based interventions delivered to adults (mean age 18-65 years) with long-lasting (≥6 months) difficulties following acquired brain injury (ABI).

DESIGN

Systematic review of controlled intervention studies published until February 2021.

MAIN MEASURES

Systematic searches in databases (MEDLINE, PsycINFO, Database of Abstracts of Reviews of Effects [Cochrane Library], and Cochrane Central Register of Controlled Trials [Cochrane Library]) and inclusion of English peer-reviewed full-text articles; randomized or controlled community-based intervention studies; sample size of 20 or more participants; and 3 or more intervention sessions. Two reviewers independently extracted data for the synthesis and assessed the methodological quality. Data extraction included study characteristics, demographics of participants, content and dose of intervention, outcome measures, and findings.

RESULT

The search returned 7386 publications, of which 49 eligible studies were included, revealing a diverse range of community-based interventions and a myriad of outcome measures applied for assessing functional capacities, participation, and quality of life in the chronic phase of ABI. Intervention types encompassed 14 holistic, 23 physical, and 12 specific interventions. A large heterogeneity regarding intervention frequency and intensity was found. Meta-analyses performed on the holistic, physical, and specific interventions did not indicate any significant pooled effects but showed highly variable effects between individuals, both in persons with traumatic and nontraumatic brain injuries.

CONCLUSIONS

Because of lack of pooled effects within types of community-based interventions, specific evidence-based recommendations within holistic, physical, and specific interventions designed to mitigate long-lasting ABI problems cannot be made. This review highlights the need for future studies to address methodological issues concerning larger sample size, lack of clear description interventions and comparator, missing reports of effects in change scores, need for consistent use of recommended outcome measures, and investigating the wide variety in intervention responsiveness among participants with ABI.

Early Supported Discharge for Neurorehabilitation Following Acquired Brain Injury

Introduction: Early Supported Discharge (ESD) is a clinical flow management service offering interdisciplinary rehabilitation, wherein patients are provided supported in-home rehabilitation treatment; in comparison to conventional hospital-based rehabilitation model of service delivery. There has been little research into the functional outcomes for other types of acquired brain injury (ABI).

Methods: In this prospective cohort study, ABI patients presenting at a level I trauma center in Calgary, Canada were placed in either an ESD program or conventional inpatient rehabilitation (IPR) program based on their medical history and presentation. A small number of patients completed both programs (ESD+IPR group). ESD therapies were designed to emulate IPR. Participants completed professionally-rated Mayo-Portland Adaptability Index-4 (MPAI), Quality of Life after Brain Injury (QOLIBRI), Generalized Anxiety Questionnaire-7 (GAD7), Montreal Cognitive Assessment (MoCA), and Patient Health Questionnaire-9 (PHQ9) surveys at 1, 3, and 6 months following initial assessment pre-rehabilitation. Caregivers completed the Zarit Burden Interview (ZBI) at the same time points. The Supervision Rating Scale (SRS) and Disability Rating Scale (DRS) were completed at admission to rehabilitation and all follow-ups. Generalized estimate equations models were used to describe the three groups over time, including age as a covariate.

Results: Significant effects of time were reported in the MPAI participant sub-score in the ESD and IPR groups (χ(2)2 = 42.429, p < 0.000; χ(2)2 = 9.773, p = 0.008), showing significantly higher scores between 1 and 3 month timepoints for both groups. ZBI scores were significantly lower in the ESD group at 1 month compared to 3 and 6 months (χ(2)2 = 31.252, p < 0.001). The proportion of patients with medical complications during rehabilitation was 25.3% in ESD compared to 74.7% patients in IPR.

Conclusions: Improvements in functional outcomes were evident in patients participating in ESD and IPR, with more medical complications reported in the IPR group. Caregiver burden lessened over time in the ESD group but not in the IPR group. Both ESD and ESD+IPR groups can be considered viable alternatives to traditional inpatient rehabilitation. A randomized control trial would be required to properly compare rehabilitation streams. Further investigation into affective and lifestyle elements of ABI recovery would also improve our understanding of targeted neurorehabilitation in this population.

Effectiveness of Post-Hospital Intensive Residential Rehabilitation after Acquired Brain Injury: Outcomes of 256 Program Completers Compared to Participants in a Residential Supported Living Program

Post-hospital residential brain injury rehabilitation outcomes research is a complicated undertaking because of the custom-tailoring of interventions needed to meet the complex and unique need of each individual. As such, there tends to be great variability across program settings, which generally limits large-scale intervention studies. Growing literature demonstrates that post-hospital residential programs are beneficial. The main criticisms of this work include the absence of randomized-controlled studies, lack of clear definition of treatment types/settings, and small sample sizes. This study is a retrospective analysis of program evaluation data for a large, multi-site, national provider of post-hospital residential brain injury rehabilitation services. Specifically, outcome of participants completing Intensive Residential Rehabilitation (IRR) were compared to participants in the Residential Supported Living (RSL) program. Results demonstrate that participants in the IRR program improve and that participants in the RSL group preserve functional ability over time, suggesting that each program is effective in achieving its intended outcome. The IRR treatment group achieved significantly better outcomes than those in the same setting not receiving the intervention. To isolate treatment effects of IRR, a subsample of participants across program types were matched on time post-injury, age, and sex. The treatment effect of IRR was strengthened in this analysis, suggesting that chronicity alone does not account for the variance between the two groups.

Post-Inpatient Brain Injury Rehabilitation Outcomes: Report from the National OutcomeInfo Database

This study examined outcomes for intensive residential and outpatient/community-based post-inpatient brain injury rehabilitation (PBIR) programs compared with supported living programs. The goal of supported living programs was stable functioning (no change). Data were obtained for a large cohort of adults with acquired brain injury (ABI) from the OutcomeInfo national database, a web-based database system developed through National Institutes of Health (NIH) Small Business Technology Transfer (STTR) funding for monitoring progress and outcomes in PBIR programs primarily with the Mayo-Portland Adaptability Inventory (MPAI-4). Rasch-derived MPAI-4 measures for cases from 2008 to 2014 from 9 provider organizations offering programs in 23 facilities throughout the United States were examined. Controlling for age at injury, time in program, and time since injury on admission (chronicity), both intensive residential (n = 205) and outpatient/community-based (n = 2781) programs resulted in significant (approximately 1 standard deviation [SD]) functional improvement on the MPAI-4 Total Score compared with supported living (n = 101) programs (F = 18.184, p < 0.001). Intensive outpatient/community-based programs showed greater improvements on MPAI-4 Ability (F = 14.135, p < 0.001), Adjustment (F = 12.939, p < 0.001), and Participation (F = 16.679, p < 0.001) indices than supported living programs; whereas, intensive residential programs showed improvement primarily in Adjustment and Participation. Age at injury and time in program had small effects on outcome; the effect of chronicity was small to moderate. Examination of more chronic cases (>1 year post-injury) showed significant, but smaller (approximately 0.5 SD) change on the MPAI-4 relative to supported living programs (F = 17.562, p < 0.001). Results indicate that intensive residential and outpatient/community-based PIBR programs result in substantial positive functional changes moderated by chronicity.

Changes in aspects of social functioning depend upon prior changes in neurodisability in people with acquired brain injury undergoing post-acute neurorehabilitation

Post-acute community-based rehabilitation is effective in reducing disability. However, while social participation and quality of life are valued as distal outcomes of neurorehabilitation, it is often not possible to observe improvements on these outcomes within the limited time-frames used in most investigations of rehabilitation. The aim of the current study was to examine differences in the sequence of attainments for people with acquired brain injury (ABI) undergoing longer term post-acute neurorehabilitation. Participants with ABI who were referred to comprehensive home and community-based neurorehabilitation were assessed at induction to service, at 6 months and again at 1.5 years while still in service on the Mayo-Portland Adaptability Index (MPAI-4), Community Integration Questionnaire, Hospital Anxiety and Depression Scale, and World Health Organisation Quality of Life measure. At 6 months post-induction to service, significant differences were evident in MPAI abilities, adjustment, and total neurodisability; and in anxiety and depression. By contrast, there was no significant effect at 6 months on more socially oriented features of experience namely quality of life (QoL), Community Integration and Participation. Eighteen month follow-up showed continuation of the significant positive effects with the addition of QoL-related to physical health, Psychological health, Social aspects of QoL and Participation at this later time point. Regression analyses demonstrated that change in QoL and Participation were dependent upon prior changes in aspects of neurodisability. Age, severity or type of brain injury did not significantly affect outcome. Results suggest that different constructs may respond to neurorehabilitation at different time points in a dose effect manner, and that change in social aspects of experience may be dependent upon the specific nature of prior neurorehabilitation attainments.
