Minimum Data Set
Also written as: MDS — Minimum Data Set
A standardized federally mandated assessment instrument used in long-term care settings in the United States to evaluate the clinical, functional, and psychosocial status of residents.
Full Definition
The Minimum Data Set (MDS), currently in version 3.0, is required under US federal regulations for all Medicare- and Medicaid-certified nursing facilities and is completed at specified intervals during a resident's stay. It captures data on cognition, communication, mood, behavior, functional status, continence, disease diagnosis, and health conditions, forming the basis for care planning and reimbursement classification. Editors working with long-term care or post-acute rehabilitation documents in the US market must recognize the MDS as a specific regulatory document, distinct from general intake assessments. The MDS drives assignment to Resource Utilization Groups (RUGs) or Patient-Driven Payment Model (PDPM) categories, terminology that frequently appears in adjacent documents. It should always be written as 'Minimum Data Set' with initial capitals, not 'minimum data set'.
Usage
Usage note: In US long-term care documents, MDS refers specifically to this CMS instrument. Do not use 'MDS' as a generic term for 'minimal dataset' in clinical rehabilitation contexts.
