According to NCQA (2014), HEDIS is a tool used by more than 90% of America’s health plans to measure performance on important dimensions of care and service. HEDIS consists of 81 measures across 5 domains of care, there are so many plans that use HEDIS and the measures are so specifically defined it can be used to make comparisons among plans. To ensure that HEDIS stays current the National Committee of Quality Assurance (NCQA) has established a process to evolve the measurement set for each year through its committee on performance measurement. The National Committee of Quality Assurance…show more content… A patient may be treated in a hospital’s observation unit to determine if the condition improves sufficiently before the patient can be discharged. If the condition neither worsens nor improves the physician may decide to admit the patient as an inpatient. This is the admissions that will follow medical observation.…show more content… It also forms the basis for measuring patient outcomes for purpose of outcome base -quality improvement (OBQI). However, OASIS is the back bone of Medicare’s partnership with the home care industry that fosters and monitors to improve home health outcomes and is dedicated in improving integral parts of revised of conditions in participation of Medicare certified home health agencies(HHAs). Most of the data items that are within the OASIS is in the context of a CMS-funded national research program, which is (co-funded by the Robert Wood Johnson foundation) that is to develop a system of outcome measures for home health care measures. This particular program along with OASIS had 10 years to develop. The core data are through iterations of clinical and empirical research. There were items that were added through a work group of home care of group experts. The OASIS items have utility for outcome monitoring, clinical assessment, care planning, and other internal-agency applications.
