About the Data
The OASIS is a standardized assessment tool completed by trained clinicians to measure outcomes for all adult Medicare beneficiaries who are receiving skilled home health services reimbursed by Medicare. We define unique home health stays as new OASIS start of care dates that span to the first OASIS discharge assessment. For outcome measures that are continually assessed throughout an individual's home health stay, we select the first non-missing value, unless otherwise specified in the accompanying data dictionary. THe data includes information on both Traditional medicare and Medicare Advantage beneficiaries, aggregating at three yearly levels: Home health agency, county, and state geography assigned according tot he beneficiary's residence as recorded in the Master Beneficiary Summary File. More information about OASIS data sets and user manuals can be found at https://www.cms.gov/medicare/quality/home-health.
