Pharmacoepidemiological analysis of type 1 diabetes mellitus insulin therapy (According to the Moscow segment of the State Register of Diabetes Mellitus)

BACKGROUND : When developing programs for state reimbursement of the cost of medical services and medicines, when providing assistance to patients suffering from type 1 diabetes mellitus (DM1), data based on the results of pharmacoepide-miological studies (FEI) conducted in real clinical practice of treating patients are needed. The obtained results of the analysis of drug consumption allow us to study the most commonly used insulin therapy regimens and their compliance with modern clinical recommendations. Calculations of the weighted average cost of conducting hypoglycemic therapy in DM1 can be used for further pharmacoeconomical calculations, including analysis of the medical and social cost of the disease. AIM : To conduct a pharmacoepidemiological analysis of the consumption of insulin preparations according to the ATX /DDD methodology, to study the modes of insulin administration and the ratio of the weighted average cost of insulin therapy components per 1 patient with DM1 per year in the outpatient practice of treatment with the introduction of insulin in the mode of multiple injections of insulin (MII) and during continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS : A retrospective continuous cohort analytical pharmacoepidemiological study was conducted on the basis of the SRDM database (status as of 01/01/2020), in which 17,617 patients with T1DM aged 18 years and older were registered at the time of the study. RESULTS : 90% of patients received analogues of human insulin in the MII mode using syringe pens, 8.6% used the CSII mode. In 34.5% of patients with DM1 HbA1c was <7%, the proportion of patients with HbA1c >8% was 28%. The average cost of insulin therapy per 1 person per year was 54,977 rubles. The cost of basal insulin treatment per 1 patient per year was approximately 1.5 times higher than the cost of bolus insulin during insulin therapy in the MII mode (33,960 rubles and 21,017 rubles, respectively). The weighted average cost of insulin per 1 patient per year for CSII was 31,822 rubles. CONCLUSION : The majority of patients with DM1 in the study cohort received analogues of human insulin in the basic bolus mode of MII using syringe pens, which corresponds to existing clinical recommendations. The proportion of patients achieving the goals of glycemic control is comparable to the data obtained on the basis of registers of diabetic patients in other economically developed countries
