Information for Health Care Providers - OASIS

OASIS (Outcome and Assessment Information Set) is a key component of the Centers for Medicare and Medicaid (CMS) partnership with the home care industry to foster and monitor improved home health care outcomes. It is also proposed to become an integral part of the revised Conditions of Participation for Medicare-certified home health agencies (HHAs).

The Outcome and Assessment Information Set-C (OASIS-C) is a group of data elements that:

Represent core items of a comprehensive assessment for an adult home care patient; and
Form the basis for measuring patient outcomes for the purposes of outcome-based quality improvement (OBQI)
