Functionality, as measured by activities of daily living (ADL), is the most important predictor of the cost of nursing home care. Data from a field-test version of the federally mandated Minimum Data Set (MDS) were examined using analysis of variance (ANOVA) and recursive partitioning methods to determine the relationships between ADL limitations and nursing cost (wage-weighted nursing time) among nursing home residents (n = 6,663). From this analysis, an index based on limitations in four ADLs was created. The developed ADL index is a readily determined measure of functional status useful in allocating nursing staff within nursing homes and in comparing the functional status of groups of residents, explaining 30 percent of variance in nursing costs among nursing home residents.
以日常生活活动能力（ADL）衡量的功能状况是疗养院护理成本的最重要预测指标。我们使用方差分析（ANOVA）和递归划分方法，对联邦政府规定的最低数据集（MDS）实地测试版本中的数据进行了分析，以确定疗养院居民（n = 6,663）的ADL限制与护理成本（工资加权护理时间）之间的关系。通过该分析，创建了一个基于四项ADL限制的指数。所开发的ADL指数是一种易于确定的功能状态测量方法，有助于在疗养院中分配护理人员，并比较居民群体的功能状态，可解释疗养院居民护理成本中30%的方差。
