Factors influencing the outcome of acute rehabilitation: Functional independence measure assessment at discharge

Abstract

[Purpose] The purpose of this study was to identify factors related to the discharge destination of 126 patients who underwent acute rehabilitation. [Subjects and Methods] We assessed Activities of Daily Living (ADL) of 126 patients, based on the Functional Independence Measure (FIM) score at discharge and analyzed whether the FIM score was useful for predicting the outcome by discriminant analysis. [Results] The correct classification rate of our model was 93.7%. Control of excretion, self care, and transfer were the factors with the greatest influence on the outcome. When our model was tested with 40 patients for validation, the correct classification rate was 77.5%. [Conclusion] ADL is a useful indicator of the discharge destination of patients undergoing acute rehabilitation. Further research is needed to improve our model, so that it includes disease characteristics and social factors.
