Prior rehabilitation outcome studies had many weaknesses. They had: a) evaluated rehabilitation effects only in isolated subgroups, b) focused on functional ability rather than on quality of life, c) not used randomized control groups, and d) had inadequate sample sizes. Differences in methodological approaches have resulted in inconsistent findings. The lack of long-term benefits suggests that services may need to be continued at home or in subacute care settings to optimize their effectiveness. Unfortunately, prior research did not include behavioral outcomes. The potential benefits of rehabilitative care could thus not be evaluated by these studies in more meaningful detail, and they did not accurately reflect the psychosocial objectives of rehabilitation.
The goal of this study was to measure the additive effect of outpatient, subacute rehabilitation as follow-up services to acute, inpatient rehabilitation on adults diagnosed with a disabling disorder in four major diagnostic groups (nervous, circulatory, musculoskeletal, and injury).
A randomized clinical trial was conducted to determine the effects of subacute rehabilitative care on: 1) physical function, 2) health and mental health, 3) mortality, 4) family function, 5) personal adjustment, and 6) use of health care resources. Patients hospitalized for the first time with a disabling condition [n=180] were provided inpatient rehabilitation and then randomly assigned to either subacute rehabilitation at home [n=90] or to usual outpatient follow-up [n=90] in which only medical services were provided but no scheduled rehabilitative therapies were offered. To compare the two groups, analysis of covariance was conducted for the outcome variables. The between subjects factor was subacute rehabilitative care versus usual medical services as an outpatient.
The major finding of the study was that there was no significant effect of the study intervention on any study outcome.
Some prior clinical trials had noted a short term treatment effect on functional ability but not on mortality, need for skilled care, or for health or mental health status. Any long term benefit, however, may not be detectable across disability categories and may required closer evaluation in studies with a more homogeneous population than in the current study. Providing follow-up services to all clients is apparently not beneficial. Future studies should determine if services are more effective when provided to those with the most unmet rehabilitative needs.
