OASIS (Outcomes Assessment Information
Set) is a set of core assessment items for adult home care patients from which quality-based outcome measurements may be derived. This is a standardized home care assessment tool that was established by The Centers for Medicare and Medicaid Services (CMS). For the VNSNY initiative, they initially abstracted data collected as part of usual care to identify patients with cognitive impairment. VNSNY also used assessment data collected through this tool to evaluate outcomes. A copy of this tool is available on the CMS website at: www.cms.gov/OASIS.
