HEDIS is a tool used by many health plans in the United States to measure performance of managed care and services. It is a trademark that was developed and maintained by the National Committee for Quality Assurance. "HEDIS" stands for "Healthcare Effectiveness Data and Information Set."
Many health plans in the U.S. collect the HEDIS data, allowing easy comparison of different plans based on their performance. Health plans also use the HEDIS results to identify the crucial areas that need improvement in order to ensure quality. Consumers and employers use the HEDIS data to choose the best health plans that suit their specific needs.
