This study evaluated the extent to which rehabilitation outcomes and resource use can be predicted by functional status measures. Linear measures of motor and cognitive function were derived from the Functional Independence Measure for a sample of 27,699 patients undergoing initial rehabilitation. Admission functional status was consistently related to discharge function and length of stay, though the strength of these associations varied with impairment. Motor function was a stronger predictor of length of stay than was cognitive function for all impairments. However, the unique contribution of cognitive function was apparent for specific impairment groups. The predicted variance at discharge in motor function averaged 55%, 70% in cognitive function, and 20% in length of stay. These results support the use of functional status measures in the development of rehabilitation resource use models. Recommendations for future research are proposed.
本研究评估了功能状态测量对康复结局和资源利用的预测程度。对27699例接受初始康复治疗的患者样本，采用功能独立性测量得出运动和认知功能的线性测量值。入院时的功能状态与出院时的功能及住院时间始终相关，尽管这些关联的强度因损伤情况而异。对于所有损伤类型，运动功能对住院时间的预测作用比认知功能更强。然而，认知功能的独特贡献在特定损伤组中较为明显。出院时运动功能的预测方差平均为55%，认知功能为70%，住院时间为20%。这些结果支持在康复资源利用模型的开发中使用功能状态测量。并提出了对未来研究的建议。
