Assesses the percentage of members 18–75 years of age with diabetes (type 1 or type 2) whose HbA1c was at the following levels:
- HbA1c control (<8.0%).
- HbA1c poor control (>9.0%).
Why It Matters
Diabetes is a chronic condition marked by high blood sugar due to the body’s inability to make or use insulin. The American Diabetes Association recommends an A1c goal between 7.0% and 8.0%, depending on patient characteristics (e.g., life expectancy, low blood sugar risk),1 but over 13% of adults diagnosed with diabetes have an A1c greater than 9.0%.2 Proper blood sugar management can prevent serious health conditions, including heart disease, vision loss and kidney disease.3 With support from health care providers, patients can manage their blood sugar by identifying causes of an increase or decrease in blood sugar, tracking physical activity, eating meals at regular times and controlling food portions. Monitoring and managing blood sugar is essential for reducing risk of complications and prolonging life.
