Role and Outcomes of Supported Community Living Programs in Post-Hospital Brain Injury Rehabilitation Programs.

OBJECTIVES: (1) To determine the proportion of participants admitted to supported community living (SCL) programs over the course of 5 years who improve, decline, or maintain functioning and community integration and (2) to examine the associations of time since injury, time in program, and age to their functional trajectory. SETTING: Data from SCL programs serving individuals with acquired brain injury (ABI). PARTICIPANTS: 104 individuals with traumatic brain injury (TBI), stroke, or other ABI. MAIN MEASURES: Sex, age, time since injury, Mayo-Portland Adaptability Inventory (4th edition; MPAI-4). DESIGN: Retrospective analyses of MPAI-4 total and MPAI-4 indices using Linear Mixed Models (LMM) of Rasch-derived T-scores from admission to 5 years into service delivery. RESULTS: MPAI-4 total, index, and subscale scores for yearly intervals of SCL services from admission to 5 years showed a high degree of stability in function (defined using the standard error of measurement (SEM) for the MPAI-4, defined as change ≥3 T-score points) with all intervals showing at least 89% of patients with improved scores or no change. The rate of change over time did not significantly vary by time since injury, time in the program, or age. CONCLUSIONS: The expectations for services in the SCL portion of the care continuum for ABI are unique. Unlike intensive rehabilitation programs which focus on improvement often earlier in the course of recovery, the goal of SCL services is sustained functioning over the long term. Analyses reported here indicate this can be achieved for at least 5 years, potentially mitigating the increased risk for rehospitalization and increased care needs in the ABI population. This study highlights a key finding of MPAI-4 stability within these understudied brain injury service lines. Additional exploration of comorbidities and more nuanced delineation of diagnostic information could further clarify factors influencing outcome stability over time.

The Foundation to Advance Brain Rehabilitation: Organization, History, and Collaborative Database.

OBJECTIVE: To describe the history, organization, goals, and data management procedures of the Foundation to Advance Brain Rehabilitation (FABR). SETTING: Postacute brain injury rehabilitation following acute inpatient care. KEY POINTS: FABR was incorporated in 2019 with a primary mission to advance brain rehabilitation through scientific and strategic analysis of industry-wide data. Contributing FABR member organizations include Bancroft NeuroRehab, Collage Rehabilitation Partners, On With Life, Pate NeuroRehabilitation, and Shepherd Center. These organizations contribute demographic, admission, discharge, and follow-up data on persons served in 5 types of intensive posthospital brain injury rehabilitation programs (neurobehavioral residential, neurorehabilitation residential, home and community neurorehabilitation, day treatment, and outpatient) and 3 types of supported living programs (neurobehavioral residential, residential, and community-based) to a collaborative database managed by Inventive Software Solutions. Inventive Software Solutions provides FABR researchers with a dataset that is de-identified both for participant and organizational identifying information.

Evaluation of Posthospital Brain Injury Rehabilitation Outcomes With Quasi-Experimental Controls.

OBJECTIVE: To further evaluate, using quasi-experimental methodologies, posthospital brain injury rehabilitation outcomes described in an accompanying report of a large observational study (n = 2120). SETTING: Data from Intensive Rehabilitation (IR: Residential Neurobehavioral, Residential Neurorehabilitation, Home and Community Neurorehabilitation, Day Treatment, Outpatient Neurorehabilitation) and Supported Living (SL) programs serving individuals with acquired brain injury (ABI). PARTICIPANTS: Two hundred twenty-eight individuals with traumatic brain injury, stroke, or other ABI in propensity score analysis; 1344 in analysis by extent of recommended treatment completed (TC) rating. MAIN MEASURES: Sex, age, time since injury, Mayo-Portland Adaptability Inventory-4th edition (MPAI-4) Rasch-derived T-scores, and TC rating. DESIGN: Analyses of covariance (1) of discharge MPAI-4 Total, index, and subscale T-scores on propensity score-matched samples of IR and SL participants controlling for admission scores and (2) of MPAI-4 T-scores by TC rating and diagnostic category. RESULTS: Propensity score-matched groups showed superior outcomes for IR participants compared to SL participants on MPAI-4 Total T-score (F = 77.21, P < .001; partial η2 = 0.257) and all MPAI-4 index and subscale T-scores controlling for sex, age, and baseline scores. Participants with traumatic brain injury and stroke who completed the recommended course of rehabilitation had superior outcomes on all MPAI-4 T-scores compared to those who completed less than or much less than the recommended treatment. No additional benefit was apparent for those who completed more than the recommended course. The association between TC rating and outcome was not significant for the other ABI group. CONCLUSIONS: These analyses using quasi-experimental controls provide more scientifically rigorous evidence of the benefit of IR provided through posthospital brain injury rehabilitation programs after acute inpatient care, consistent with the results of numerous observational studies. However, improved internal validity limits external validity and generalization. The absence of a significant association between TC rating and outcomes for the other ABI group most likely reflects the difficulty prescribing rehabilitation for this highly heterogeneous group.

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 η2 = .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 η2 = .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 η2 = .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.

Distinguishing Characteristics of Admissions to Various Types of Posthospital Brain Injury Rehabilitation Programs.

OBJECTIVE: Describe and compare the demographic characteristics and disability profiles of individuals admitted to 6 types of posthospital brain injury rehabilitation (PHBIR) programs. SETTING: Data from Residential Neurobehavioral, Residential Neurorehabilitation, Home and Community Neurorehabilitation, Day Treatment, Outpatient Neurorehabilitation, and Supported Living programs serving individuals with acquired brain injury (ABI). PARTICIPANTS: Two thousand twenty-eight individuals with traumatic brain injury (TBI), stroke, or other ABI. MAIN MEASURES: 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 comparing diagnostic categories and program types within diagnostic categories. RESULTS: Participants with TBI were predominantly male, and those with stroke were generally older. Admissions to more intensive and supervised programs (residential neurobehavioral and residential neurorehabilitation) generally showed greater disability than admissions to home and community programs who were more disabled than participants in day treatment and outpatient programs. Residential neurobehavioral and supported living program participants generally were male and had TBI. Home and community admissions tended to be more delayed than residential neurorehabilitation admissions. The majority of those with other ABI were admitted to outpatient rather than more intensive programs. Additional analyses demonstrated significant differences in MPAI-4 profiles among the various program types. CONCLUSIONS: Admissions with TBI, stroke, and other ABI to PHBIR differ in demographic factors and disability profiles. When examined within each diagnostic category, demographic features and disability profiles also distinguish among admissions to the various program types. Results provide insights about decision-making in referral patterns to various types of PHBIR programs, although other factors not available for analysis (eg, participant/family preference, program, and funding availability) likely also contribute to admission patterns.

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

The objective of the study was to develop statistical formulas to predict levels of community participation on discharge from post-hospital brain injury rehabilitation using retrospective data analysis. Data were collected from seven geographically distinct programmes in a home- and community-based brain injury rehabilitation provider network. Participants were 642 individuals with post-traumatic brain injury. Interventions consisted of home- and community-based brain injury rehabilitation. The main outcome measure was the Mayo-Portland Adaptability Inventory (MPAI-4) Participation Index. Linear discriminant models using admission MPAI-4 Participation Index score and log chronicity correctly predicted excellent (no to minimal participation limitations), very good (very mild participation limitations), good (mild participation limitations), and limited (significant participation limitations) outcome levels at discharge. Predicting broad outcome categories for post-hospital rehabilitation programmes based on admission assessment data appears feasible and valid. Equations to provide patients and families with probability statements on admission about expected levels of outcome are provided. It is unknown to what degree these prediction equations can be reliably applied and valid in other settings.

Effectiveness of home- and community-based rehabilitation in a large cohort of patients disabled by cerebrovascular accident: evidence of a dose-response relationship.

OBJECTIVES: To (1) assess the effectiveness of home- and community-based rehabilitation (HCBR) in a large cohort of individuals with disabilities secondary to cerebrovascular accident (CVA); and (2) evaluate the responsiveness to treatment of the Mayo-Portland Adaptability Inventory (MPAI-4) to changes resulting from HCBR in this patient group. DESIGN: Retrospective analysis of program evaluation data for treatment completers and noncompleters. SETTING: HCBR conducted in 7 geographically distinct U.S. cities. PARTICIPANTS: Individuals with CVA (n=738) who completed the prescribed course of rehabilitation (completed course of treatment [CCT]) compared with 150 individuals who were precipitously discharged (PD) before program completion. INTERVENTION: HCBR delivered by certified professional staff on an individualized basis. MAIN OUTCOME MEASURES: Mayo-Portland Adaptability Inventory (MPAI-4) completed by professional consensus on admission and at discharge. RESULTS: With the use of analysis of covariance, MPAI-4 total scores at discharge for CCT participants were compared with those of PD participants, with admission MPAI-4, age, length of stay, and time since event as covariates. CCT participants showed greater improvement than PD participants (F=99.48, P<.001) with a moderate effect size (partial η(2)=.10). Group differences and effect sizes were similar for the 3 index scores: Ability (F=75.96, P<.001; partial η(2)=.08), Adjustment (F=99.67, P<.001; partial η(2)=.10), and Participation (F=69.15, P<.001; partial η(2)=.07). CONCLUSIONS: Individuals in the CCT group who received the entire planned course of HCBR showed greater improvement on all MPAI-4 indexes than those in the PD group who were discharged before completing the prescribed program. This dose-response relationship provides evidence of a causal relationship between treatment and outcome.

Mayo-Portland adaptability inventory: comparing psychometrics in cerebrovascular accident to traumatic brain injury.

OBJECTIVES: (1) To evaluate the measurement reliability and construct validity of the Mayo-Portland Adaptability Inventory, 4th revision (MPAI-4) in a sample consisting exclusively of patients with cerebrovascular accident (CVA) using single parameter (Rasch) item-response methods; (2) to examine the differential item functioning (DIF) by sex within the CVA population; and (3) to examine DIF and differential test functioning (DTF) across traumatic brain injury (TBI) and CVA samples. DESIGN: Retrospective psychometric analysis of rating scale data. SETTING: Home- and community-based brain injury rehabilitation program. PARTICIPANTS: Individuals post-CVA (n=861) and individuals with TBI (n=603). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: MPAI-4. RESULTS: Item data on admission to community-based rehabilitation were submitted to Rasch, DIF, and DTF analyses. The final calibration in the CVA sample revealed satisfactory reliability/separation for persons (.91/3.16) and items (1.00/23.64). DIF showed that items for pain, anger, audition, and memory were associated with higher levels of disability for CVA than TBI patients; whereas, self-care, mobility, and use of hands indicated greater overall disability for TBI patients. DTF analyses showed a high degree of association between the 2 sets of items (R=.92; R(2)=.85) and, at most, a 3.7 point difference in raw scores. CONCLUSIONS: The MPAI-4 demonstrates satisfactory psychometric properties for use with individuals with CVA applying for interdisciplinary posthospital rehabilitation. DIF reveals clinically meaningful differences between CVA and TBI groups that should be considered in results at the item and subscale level.

Rasch measurement analysis of the Mayo-Portland Adaptability Inventory (MPAI-4) in a community-based rehabilitation sample.

The precise measurement of patient outcomes depends upon clearly articulated constructs and refined clinical assessment instruments that work equally well for all subgroups within a population. This is a challenging task in those with acquired brain injury (ABI) because of the marked heterogeneity of the disorder and subsequent outcomes. Although essential, the iterative process of instrument refinement is often neglected. This present study was undertaken to examine validity, reliability, dimensionality and item estimate invariance of the Mayo-Portland Adaptability Inventory - 4 (MPAI-4), an outcome measure for persons with ABI. The sampled population included 603 persons with traumatic ABI participating in a home- and community-based rehabilitation program. Results indicated that the MPAI-4 is a valid, reliable measure of outcome following traumatic ABI, which measures a broad but unitary core construct of outcome after ABI. Further, the MPAI-4 is composed of items that are unbiased toward selected subgroups except where differences could be expected [e.g., more chronic traumatic brain injury (TBI) patients are better able to negotiate demands of transportation than more acute TBI patients]. We address the trade-offs between strict unidimensionality and clinical applicability in measuring outcome, and illustrate the advantages and disadvantages of applying single-parameter measurement models to broad constructs.

Effectiveness of community-based rehabilitation after traumatic brain injury for 489 program completers compared with those precipitously discharged.

OBJECTIVE: To evaluate outcomes of home- and community-based postacute brain injury rehabilitation (PABIR). DESIGN: Retrospective analysis of program evaluation data for treatment completers and noncompleters. SETTING: Home- and community-based PABIR conducted in 7 geographically distinct U.S. cities. PARTICIPANTS: Patients (N=489) with traumatic brain injury who completed the prescribed course of rehabilitation (completed-course-of-treatment [CCT] group) compared with 114 who were discharged precipitously before program completion (precipitous-discharge [PD] group). INTERVENTION: PABIR delivered in home and community settings by certified professional staff on an individualized basis. MAIN OUTCOME MEASURES: Mayo-Portland Adaptability Inventory (MPAI-4) completed by means of professional consensus on admission and at discharge; MPAI-4 Participation Index at 3- and 12-month follow-up through telephone contact. RESULTS: Analysis of covariance (CCT vs PD group as between-subjects variable, admission MPAI-4 score as covariate) showed significant differences between groups at discharge on the full MPAI-4 (F=82.25; P<.001), Ability Index (F=50.24; P<.001), Adjustment Index (F=81.20; P<.001), and Participation Index (F=59.48; P<.001). A large portion of the sample was lost to follow-up; however, available data showed that group differences remained statistically significant at follow-up. CONCLUSIONS: Results provided evidence of the effectiveness of home- and community-based PABIR and that treatment effects were maintained at follow-up.
