Progress Assessed With the Mayo-Portland Adaptability Inventory in 604 Participants in 4 Types of Post–Inpatient Rehabilitation Brain Injury Programs

Abstract

Eicher V, Murphy MP, Murphy TF, Malec JF. Progress assessed with the Mayo-Portland Adaptability Inventory in 604 participants in 4 types of post–inpatient rehabilitation brain injury programs. Objective To compare progress in 4 types of post–inpatient rehabilitation brain injury programs. Design Quasiexperimental observational cohort study. Setting Community and residential. Participants Individuals (N=604) with acquired brain injury. Interventions Four program types within the Pennsylvania Association of Rehabilitation Facilities were compared: intensive outpatient and community-based rehabilitation (IRC; n=235), intensive residential rehabilitation (IRR; n=78), long-term residential supported living (SLR; n=246), and long-term community-based supported living (SLC; n=45). With the use of a commercial web-based data management system developed with federal grant support, progress was examined on 2 consecutive assessments. Main Outcome Measure Mayo-Portland Adaptability Inventory (MPAI-4). Results Program types differed in participant age (F=10.69, P<.001), sex (χ 2=22.38, P<.001), time from first to second assessment (F=20.71, P<.001), initial MPAI-4 score (F=6.89, P<.001), and chronicity (F=13.43, P<.001). However, only initial MPAI-4 score and chronicity were significantly associated with the second MPAI-4 rating. On average, SLR participants were 9.1 years postinjury compared with 5.1 years for IRR, 6.0 years for IRC, and 6.8 years for SLC programs. IRR participants were more severely disabled per MPAI-4 total score on admission than the other groups. Controlling for these variables, program types varied significantly on second MPAI-4 total score (F=5.14, P=.002). Both the IRR and IRC programs resulted in significant functional improvement across assessments. In contrast, both the SLR and SLC programs demonstrated relatively stable MPAI-4 scores. Conclusions Results are consistent with stated goals of the programs; that is, intensive programs resulted in functional improvements, whereas supported living programs produced stable functioning. Further studies using data from this large, multiprovider measurement collaboration will potentially provide the foundation for developing outcome expectations for various types of postacute brain injury programs.
