POET2 registry: Comparison of annual direct medical costs of treating type 2 diabetes after addition of insulin NPH or insulin glargine to oral antidiabetic therapy in the Czech Republic
Abstract
Therefore, the aim of the pro-ject POET2 was to compare annual direct medical costs of treating DM2T after addition of insulin NPH or glargine to OAD therapy in a clinical practice setting in the Czech Republic. Methodology: Data collected from 1 967 patients who met the criteria for inclusion into the non-interventional prospective registry POET2 (DM2T, ongoing OAD the-rapy, glycated hemoglobin HbA1c > 6 % IFCC) and who were observed for 12 months following the start of insulin the-rapy (glargine: n = 1 061 vs NPH: n = 906) were analysed.
Costs of treatment were analysed from the perspective of health insurance companies and included costs of medication, medical devices and medical procedures. Results: In both treatment groups a reduction of HbA1c (glargine group: by 1.77 % IFCC vs NPH group: by 1.73 % IFCC) and fasting plasma glucose (glargine group: by 3.67 mmol/l vs NPH group: by 3.63 mmol/l) was observed.
Insulin glargine the-rapy was associated with the incidence of a significantly lower number of documented symptomatic hypoglycemic events (glargine group: 0.840 events per patient and year of treatment vs. NPH group: 1.053 events per patient and year of treatment; p < 0.05).
Overall annual direct medical costs associated with the initiation of basal insulin treatment were higher on average by 2547.07 CZK among patients treated with insulin glargine (glargine group: 12 173.09 ? 4 169.44 CZK vs NPH group: 9 626.02 ? 3 432.79 CZK; p < 0.001) due to higher costs of medication (glargine group: 7 992.97 ? 4 001.81 CZK vs NPH group: 3 784.2 ? 3 181.48 CZK; p < 0.001). By contrast, costs of medical devices (glargine group: 2 332.08 ? 917.84 CZK vs NPH group: 3 893.95 ? 989.79 CZK; p < 0.001) and medical procedures (glargine group: 1 848.04 ? 684.89 CZK vs NPH group: 1 947.87 ? 685.43 CZK; p < 0.001) were lower among patients treated with insulin glargine.
