The MDS is a core set of items, definitions, and response categories used to assess all of the nation's 1.5 million nursing home residents who reside in facilities participating in the Medicare or Medicaid programs. Further, the Health Care Financing Administration (HCFA) has proposed a rule that would require facilities to computerize MDS data and submit it to state and federal agencies, paving the way for a national database. This article describes the process of testing the reliability of the MDS items in 13 nursing homes in five states. The results demonstrate that MDS data gathered in a research effort attain reliabilities that make such data useful. MDS items met a standard for excellent reliability (i.e., intraclass correlation of .7 or higher) in key areas of functional status, such as cognition, ADLs, continence, and diagnoses. Sixty-three percent of the items achieved reliability coefficients of .6 or higher. Eighty-nine percent of the items in the MDS achieved .4 or higher.
最低数据集（MDS）是一套核心的项目、定义及应答类别，用于评估全国150万居住在参与医疗保险或医疗补助计划机构中的疗养院居民。此外，医疗保健财务管理局（HCFA）已提议一项规定，要求各机构将MDS数据计算机化并提交给州和联邦机构，为建立全国性数据库铺平道路。本文描述了在五个州的13家疗养院测试MDS项目可靠性的过程。结果表明，在研究中收集的MDS数据具有使其有用的可靠性。MDS项目在功能状态的关键领域，如认知、日常生活活动能力、大小便失禁及诊断方面，达到了优秀可靠性标准（即组内相关系数为0.7或更高）。63%的项目达到了0.6或更高的可靠性系数。MDS中89%的项目达到了0.4或更高。
