Show abstract
Type 2 diabetes affects hundreds of millions worldwide and is associated with significant adverse health outcomes. Optimizing glycemic control mitigates risk over time and has been shown to improve cardiovascular outcomes, reduce microvascular injury as well as decrease overall mortality. Diabetes-specific risk is determined not only by glycemic control but duration of exposure which has been historically difficult to quantify in aggregate. The model proposed in this paper computes two long-term diabetes control scores using a novel algorithm that integrates estimated average glucose as a function of time. The calculated scores are called Estimated Average Glucose Integration (eAGi) and A1c Prime (A1c). Based on previous studies demonstrating that poor glycemic control over time is associated with worse outcomes, eAGi and A1c are anticipated to provide a useful, diabetes-specific hazard appraisal for individuals in both clinical and research settings.
