Nursing Home Resident Health Status Frequency Data

Minimum Data Set Frequency data summarizes federally-mandated health status indicators for active residents in Medicare and Medicaid certified nursing homes. The dataset is produced by the United States Department of Health and Human Services, Centers for Medicare and Medicaid Services, based on clinical assessments completed by licensed professionals. Its cross-platform presence indicates established use for policy and clinical analysis.

Use Cases

• Analyzing the prevalence of specific health problems or functional capabilities among nursing home residents using coded assessment items.
• Tracking changes in resident care plans formulated from Care Area Assessments (CAAs).
• Studying admission, periodic, and discharge assessment patterns across certified facilities.
• Investigating the relationship between payment source (Medicare/Medicaid) and recorded health status indicators.

Strengths

• Data collection is federally-mandated for all residents in certified nursing homes, ensuring wide coverage.
• Assessments are completed by licensed health care professionals following specific guidelines and time frames.

Limitations

• Key metadata such as row count, column names, and exact dataset size are unavailable across all sources.
• Data files contain known formatting issues where leading zeros in codes can be stripped or code ranges misinterpreted as dates by common software like Excel.
