The Outcomes and Assessment Information Set (OASIS) was initially developed as a core group of data elements to uniformly measure and risk adjust quality measure outcomes across all home health agencies (HHAs) to serve as basis of outcomes-based quality improvement (OBQI). Select OASIS items were later identified for use in payment determination under the Prospective Payment System (PPS), and eight OASIS items remain today as part of payment determination under PDGM in addition to claims data. The OASIS and its associated Guidance Manual are periodically revised based on CMS’ addition or removal of quality measures from the Home Health Quality Reporting Program (HHQRP) or for other program requirements.
The main drivers for the upcoming version change from OASIS-D1 to OASIS-E are to increase standardization across post-acute care (PAC) settings to uniformly collect health data and to enable calculation of standardized, cross-setting quality measures — both of which are pursuant to the requirements in the provisions of the Improving Medicare Post-Acute Care Transformation (IMPACT) Act of 2014.
The changes from OASIS-D1 to OASIS-E are quite expansive, thus may take considerable time and commitment from your staff and will require significant operational and training considerations for HHAs across the country. Let’s look at four key areas of impact to help promote your agency’s success with the upcoming implementation on January 1, 2023.
