OBJECTIVE To combine items from the Functional Independence MeasureTM (FIMTM), Minimum Data Set 2.0 (MDS), and the Outcome and Assessment Information Set-B (OASIS) to reliably measure cognition across post-acute care settings and facilitate future studies of patient cognitive recovery. DESIGN Rasch analysis of data from a prospective, observational cohort study. SETTING Post-acute care inclusive of inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies. PARTICIPANTS 147 patients receiving rehabilitation services. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) FIMTM, MDS 2.0, and the OASIS-B. RESULTS Six cognition items (CogMeas) demonstrated good construct validity with no misfitting items, unidimensionality, good precision (person separation reliability .95), and an item hierarchy that reflected a clinically meaningful continuum of cognitive challenge. CONCLUSIONS This is the first attempt to combine the cognition items from the three historically, federally mandated assessments to create a common metric for cognition. These 6 items could be adopted as standardized patient assessment data elements to improve cognitive assessment across post-acute care settings.

使用 Rasch 测量结合三个联邦强制评估的项目，以可靠地测量急性护理后环境中的认知

目的 结合功能独立性测量 (FIMTM)、最小数据集 2.0 (MDS) 和结果和评估信息集-B (OASIS) 中的项目，以可靠地测量急性后护理环境中的认知，并促进未来对患者认知的研究恢复。设计 Rasch 分析来自前瞻性、观察性队列研究的数据。设置 急性期后护理，包括住院康复设施、专业护理设施和家庭保健机构。参与者 147 名接受康复服务的患者。干预 不适用。主要结果测量 FIMTM、MDS 2.0 和 OASIS-B。结果 六个认知项目 (CogMeas) 表现出良好的结构效度，没有错配项目、单维性、良好的精度（人分离信度为 0.95），以及反映具有临床意义的认知挑战连续体的项目层次结构。结论 这是首次尝试将来自三个历史悠久的、联邦政府授权的评估中的认知项目结合起来，以创建一个通用的认知指标。这 6 个项目可以用作标准化的患者评估数据元素，以改善跨急性护理设置的认知评估。
