BACKGROUND: Glikogemoglobin (HbA1c) is a key clinical marker for evaluating the effectiveness of glucose-lowering therapy for patients with diabetes mellitus (DM) and the quality of diabetic care.
 AIMS: to conduct dynamic monitoring of the quality of glycemic control in DM patients based on a comprehensive examination in mobile medical center (Diamodul) during repeated visits to the regions in 2019 compared with visits of Based Federal program Diabetes Mellitus (20052010) and data of the National diabetes register (NDR).
 MATERIALS AND METHODS: The object of the study: patients with T1DM and T2DM examined in Diamodul in 2019 in Voronezh region (Vr), Krasnodar region (Kr) (n = 600), there were dynamic group of re-examined (Vr n = 224; Kr n = 113), random group of new patients (Vr n = 72; Kr n = 191); group of adult patients from NDR with indicated HbA1c in 2019 (n = 2410067).
 RESULTS: According to Diamodul, the HbA1c levels are significantly worse than they were reported to NDR: the proportion of patients achieved HbA1c 7% for T1DM is 13.3% and 11.7%; T2DM 25.1% and 28.6%, in Kr and Vr, respectively; in NDR: T1DM 37.4%, T2DM 52.2%. The average HbA1c values in the Diamodul are higher than in NDR by 0.95% for T1DM, 1.41% for T2DM patients. The proportion of patients with HbA1c9% decrease in dynamic of examinations through years in T1: in Vr from 53.1% in 2005 and 55.8% in 2010 to 42.9% in 2019, in Kr from 53.2% in 2006 to 43.8% in 2019; also there were decreases in the average HbA1c values in Vr from 9.3% in 2005 and 9.4% in 2010 to 8.8% in 2019; in Kr from 9.1% in 2006 to 8.7% in 2019. In T2DM patients with the best parameters of DM control in a whole, the positive trends were less pronounced and are assessed as non-deterioration: the proportion of HbA1c9 % in Vr: 34.7%34.7%36.4%, in Kr 40.1%28.4%; average values of HbA1c: 8.2%8.4%8.5% and 8.6%8.4%, respectively.
 CONCLUSIONS: The data of the research clearly indicates the need for 100% inclusion of HbA1c in the examination standards in all DM patients at the primary level at least 1 time per year, in order to monitor the real clinical situation, the effectiveness of glucose-lowering therapy and its timely intensification to prevent development of complications.
