HEDIS measures have been established by NCQA to assess performance in healthcare across specific areas in which improvements have the potential to make a meaningful difference in people’s lives. They are designed to help identify gaps, monitor improvement success, and offer standards for easy plan comparison. More than 90 measures cover six domains of care: 1) Effectiveness of care 2) Access and availability of care 3) Experience of care 4) Utilization and risk adjusted utilization 5) Health plan descriptive information 6) Measures reported using electronic clinical data systems. HEDIS measures matter because they serve as a reflection of a healthcare organization’s effectiveness in delivering patient care or a payor’s effectiveness at implementing preventive healthcare initiatives. Any deficiencies can result in a decrease in HEDIS scores and impact a commercial, Medicaid, or Medicare payer’s status as a quality health plan. Remedying these gaps and improving the patient experience are essential steps in enhancing HEDIS scores.
