Outcome and Assessment Information Set (OASIS)

Home health agencies must conduct comprehensive, accurate, standardized and reproducible assessments of each patient using the Outcome and Assessment Information Set (OASIS). The automated OASIS system is a critical component of the Oklahoma State Agency and Centers for Medicare and Medicaid Services (CMS) operations, and provides the means for transmitting assessment data to CMS for validating payments under the Medicare Prospective Payment System for Home Health Agencies. CMS has provided each State with an OASIS system composed of standardized hardware and software platforms scaled to meet the State’s anticipated processing volumes. The OASIS software components are developed, distributed, maintained and upgraded centrally by CMS. The OASIS database is a federal database owned by CMS and is therefore subject to the requirements of the Federal Privacy Act and the OASIS System of Records (OASIS-SOR). The OASIS-SOR sets forth legal requirements regarding privacy and disclosure of information by CMS. The following website provides information on how to obtain data from the OASIS system:

The Quality Improvement and Evaluation Service (QIES) staff is charged with developing and implementing the delivery of health care information, providing consultative assistance regarding the OASIS process to home health agencies and maintaining the OASIS state repository for upload to the national CMS repository. Responsibilities include educating providers in the clinical methodology and completion of OASIS forms; receipting and validating OASIS records; assisting home health agencies in understanding and interpreting validation reports and the error correction process; providing routine and intermittent training to home health agency staff and home health agency surveyors; providing support to software vendors; and assisting home health agency surveyors with assessment issues in the survey process.
