Indicator Report - HEDIS (Healthcare Effectiveness Data and Information Set) Measures: Diabetes Care - Hemoglobin A1c (A1C)

The Hemoglobin A1c (A1C) test measures the level of blood glucose for persons with diabetes.

data table
This indicator contains information about Medicaid Health Maintenance Organizations (HMOs), commercial HMOs, and commercial Preferred Provider Organizations (PPOs). 2013 was the first year that PPOs were been included in this indicator and represents a significant expansion of the indicator's scope. With the inclusion of PPOs to the other plans, over 50% of Utahns who currently have health insurance are covered by one of the health plans in this indicator.

Data Notes

This quality of care measure indicator came from the Healthcare Effectiveness Data and Information Set (HEDIS), which is developed and maintained by the National Committee for Quality Assurance (NCQA). The HEDIS measurement set contains over 70 measures across eight major areas of care such as helping people stay healthy or caring for people with chronic illness. Health plans nationwide collect these measures to see how they performed in different areas of health care over the past year. Each year, Utah HMOs report HEDIS measures to the Utah Department of Health. All data are reviewed by NCQA-certified auditors to ensure that the reported HEDIS measures are representative and accurate. The National Committee for Quality Assurance (NCQA) is a non-profit organization committed to assessing, reporting on, and improving the quality of care provided by the nation's health plans.
