Effectiveness of Home- and Community-Based Rehabilitation in a Large Cohort of Patients Disabled by Cerebrovascular Accident: Evidence of a Dose-Response Relationship

ObjectivesTo (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.DesignRetrospective analysis of program evaluation data for treatment completers and noncompleters.SettingHCBR conducted in 7 geographically distinct U.S. cities.ParticipantsIndividuals 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.InterventionHCBR delivered by certified professional staff on an individualized basis.Main Outcome MeasuresMayo-Portland Adaptability Inventory (MPAI-4) completed by professional consensus on admission and at discharge.ResultsWith 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 η2=.10). Group differences and effect sizes were similar for the 3 index scores: Ability (F=75.96, P<.001; partial η2=.08), Adjustment (F=99.67, P<.001; partial η2=.10), and Participation (F=69.15, P<.001; partial η2=.07).ConclusionsIndividuals 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.
