Individualized Glycemic Control in Type 2 Diabetic Patients in Iran: A Multi-Center Data Analysis

Background: Clinical guidelines and expert committees have recently suggested that the hemoglobin A1C (HbA1c) should be individualized based on various criteria. Data regarding the achievement of individualized glycemic targets in type 2 diabetes mellitus (T2DM) patients is scant in Iran. We intended to provide information found on real-world outcomes from the perspective of an individualized recommendation.Methods: A cross-sectional analysis was conducted in 15 diabetes centers in Iran between 2013-2017. Two steps cluster sampling selection was used to recruit 1591 patients with T2DM. Considering Ismail-Beigi’s individualized strategy, the study population was categorized into five treatment intensities of HbA1c: most intensive (≤6.5%), intensive (6.5–7.0%), less intensive (~7.0%), not intensive (7.0–8.0%), and moderated (~8.0%). The percentage of patients who met their group individualized glycemic targets was estimated as the degree of achievement of each treatment intensity.Results: The cumulative incidence rate of early microvascular, advanced microvascular, and macrovascular complications was 53%, 25%, and 34%, respectively. Besides, 78% [77.6-79%] of patients did not achieve individualized glycemic targets. Conclusion: The outcome showed poor individualized glycemic control and a high incidence of diabetes complications. Considering individualized HbA1c targets for Iranian patients with T2DM is an urgent need.
