Outcome and Assessment Information Set (OASIS)
OASIS is the key component of Medicare’s partnership with the home care industry to monitor and improve home health care and is an integral part of the revised Conditions of Participation for Medicare Certified home health agencies.
OASIS is a group of data elements that represent core items of a comprehensive assessment for an adult home care patient. OASIS forms the basis for measuring patient outcomes for purposes of outcome-based quality improvement in Home Health.
The goal of OASIS is to provide a set of data items necessary for measuring patient outcomes and essential assessment elements. Overall the OASIS items have utility for outcome monitoring, clinical assessment, care planning, and other internal agency-level applications.
