Evaluating rehabilitation medicine: effects on survival, function, and home care

The goal of this study was to measure the clinical impact of rehabilitation on adults diagnosed with a disabling disorder in four major diagnostic groups (nervous, circulatory, musculoskeletal, and injury). To summarize the current knowledge in this area, a meta-analysis of rehabilitation studies was also completed. Specific objectives of the clinical trial were to determine the effects of inpatient rehabilitation on: (1) survival, (2) function, (3) home care, and related variables such as family function and use of health care resources. Patients hospitalized for the first time with a disabling condition (n = 85) were randomly assigned to inpatient rehabilitation (n = 43) or to outpatient follow-up (n = 42) in which the usual medical services were provided but no scheduled rehabilitative therapies were offered. To compare the two groups, analyses of covariance were conducted for functional ability, health care use, survival, health status, personal adjustment and family function. The between subjects factor was inpatient rehabilitation versus the control group. The within subjects factor was time of assessment (index, six months, and 1 year). No significant treatment effect was found at six months or one year for any of the variables under study using analyses of covariance. There were also no differences between groups in their use of nursing homes, length of hospital stay, survival, or in the number of hospital readmissions or clinic visits during the first year after hospital discharge. Rehabilitation did cost significantly more than medical care, primarily due to the cost of inpatient services. Some clinical trials have noted a treatment effect on functional ability but not on mortality, need for skilled care, or mental health status. The current study is consistent with these previous findings except for the lack of impact on physical function. This exception may be due to the fact that prior studies looked only at homogeneous groups, whereas the current study utilized heterogeneous grouping across four major diagnostic categories. Any apparent benefit may not be detectable across disability groups and may require more specialized scrutiny, or even tailored rehabilitative care, to detect a difference. It is recommended that health care systems evaluate the benefits of subacute rehabilitative care and consider outpatient programs that can be provided at home for implementation.
