To combine items from the Functional Independence Measure, Minimum Data Set (MDS) 2.0, and the Outcome and Assessment Information Set (OASIS)-B to reliably measure cognition across postacute care settings and facilitate future studies of patient cognitive recovery.
Rasch analysis of data from a prospective, observational cohort study.
Postacute care inclusive of inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies.
Patients (N=147) receiving rehabilitation services.
Not applicable.
Functional Independence Measure, MDS 2.0, and the OASIS-B.
Six cognition items demonstrated good construct validity with no misfitting items, unidimensionality, good precision (person separation reliability, 0.95), and an item hierarchy that reflected a clinically meaningful continuum of cognitive challenge.
This is the first attempt to combine the cognition items from the 3 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 postacute care settings.
结合功能独立性测量量表（FIM）、最低数据集 2.0（MDS 2.0）和结局与评估信息集（OASIS-B）中的项目，可靠地测量急性后期护理环境中的认知能力，并为未来的患者认知恢复研究提供便利。
前瞻性观察队列研究数据的 Rasch 分析。
包括住院康复机构、熟练护理设施和家庭健康机构在内的急性后期护理。
接受康复服务的患者（N=147）。
不适用。
功能独立性测量量表、MDS 2.0 和 OASIS-B。
6 项认知项目具有良好的结构有效性，没有不拟合项目、单维性、良好的精度（个体分离可靠性，0.95），并且项目层次反映了认知挑战的临床有意义的连续体。
这是首次尝试将这 3 项具有历史意义和联邦授权的评估中的认知项目结合起来，创建一个通用的认知衡量标准。这 6 个项目可以作为标准化患者评估数据元素被采用，以改善急性后期护理环境中的认知评估。
