| Most data items in the OASIS were derived in the context of a CMS-funded national research program (co-funded by the Robert Wood Johnson Foundation) and carried out by the Center for Health Services Research at the University of Colorado to develop a system of outcome measures for home health care. This program, and the OASIS, has evolved over time. The core data items were refined through several iterations of clinical and empirical research. Other items were added later by a work group of home care experts to augment the outcome data set with selected items deemed essential for patient assessment. Overall, the OASIS items have utility for outcome monitoring, clinical assessment, care planning, payment, compliance, and other internal agency-level applications.
OASIS data items encompass sociodemographic, environmental, support system, health status, and functional status

attributes of adult (non-maternity) patients. In addition, selected attributes of health service utilization are included. These several different types of attributes should be part of a comprehensive patient assessment, and should be supplemented with additional “non-OASIS” assessment items of the agencies choosing, in order to comply with the comprehensive assessment requirement.
All applications build on and are implemented most efficiently and effectively when OASIS data items are thoroughly integrated into the agency’s clinical documentation. Additionally, the resources utilized to ensure accurate and compliant OASIS data collection can provide the greatest return to the agency and patient when clinical staffs allow the resulting broadened scope of the comprehensive assessment to expand their knowledge of the patient’s status, and to direct appropriate care planning actions. |
