How is the A1C control measure evaluated?

The A1C control measure is evaluated through blood tests conducted at designated labs. This approach is essential because the A1C test specifically measures the average blood glucose levels over the past two to three months, providing a reliable indication of how well diabetes is being managed. Lab results from designated facilities ensure standardized testing methods and accurate reporting, which are critical for consistent evaluation of diabetes control across patient populations.

Diet and exercise logs, while important for managing diabetes, do not provide quantifiable metrics on blood glucose levels and therefore cannot be used to directly assess the A1C control measure. Insurance reporting may include various patient metrics, but it does not specifically focus on the direct results of A1C tests. Patient self-reports can offer insights into their understanding and management of their condition but are subjective and lack the scientific rigor needed for accurate assessment. Hence, the use of standardized lab testing is essential for evaluating and improving diabetes care through HEDIS measures.
