The Healthcare Effectiveness Data and Information Set (HEDIS)
The Healthcare Effectiveness Data and Information Set (HEDIS®) is a tool used by more than 90% of America’s health plans to measure performance on important dimensions of care and service. Altogether, HEDIS consists of 81 measures across five domains of care. Because so many plans collect HEDIS data and because the measures are so specifically defined, HEDIS makes it possible to compare the performance of health plan peers.
HEDIS is a registered trademark of the National Committee for Quality Assurance (NCQA).
