Healthcare Effectiveness Data and Information Set (HEDIS)

Healthcare Effectiveness Data and Information Set (HEDIS) is one of the most widely used sets of health care performance measures in the United States. It is developed and maintained by the National Committee for Quality Assurance (NCQA). These measures are designed to ensure that purchasers and consumers have the information they need to reliably compare the performance of managed health care plans. The performance measures in HEDIS are related to many significant public health issues such as cancer, heart disease, smoking, asthma, and diabetes. HEDIS also includes a standardized survey of consumers' experiences that evaluates plan performance in areas such as customer service, access to care, and claims processing.
