  • Abstract

    Overview. The Post-Acute Care Supplement (PACS) files were developed from two administrative data sets that capture assessments at multiple points in post-acute care: the Outcome and Assessment Information Set (OASIS) Summary File (OASF): 2000-2010, which covers home health care, and the Long-Term Care Annual Summary File (LTCASF): 2000-2010, which covers nursing homes. Annual files were developed for the period 2000 to 2010 that summarize health conditions, functional status, and care patterns into one observation per beneficiary per year.

    Data Access. These data are not available from ICPSR. Because the data contain confidential CMS assessment data, researchers will need to secure a data use agreement from CMS. For researchers who secure a DUA, the files will be distributed to them through the Medicare/Medicaid Research Information Center (MedRIC) (
