Change in Insulin Dose and HbA1c by Geographical Region—Results from the Diabetes Unmet Need with Basal Insulin Evaluation (DUNE) Study

DUNE, a 12-week, prospective, observational study (Feb 2015–Jul 2016) of 3139 people with T2DM, either newly (at enrollment) or recently ( 1c target achievement. Only 27.9% and 26.8% of newly and recently initiated participants, respectively, achieved individualized HbA 1c targets. This analysis investigated the regional variations in BI dose and HbA 1c change from baseline, which may help characterize treatment practices associated with improved target achievement. Mean baseline daily BI dose across regions ranged from 0.14 to 0.21 U/kg for newly initiated and 0.25 to 0.39 U/kg for recently initiated participants. Mean baseline HbA 1c ranged from 8.94 to 9.44% (newly initiated), and 8.39 to 8.78% (recently initiated) across regions. In general, HbA 1c reductions were greater in newly vs. recently initiated participants, and accompanied by greater increases in daily insulin dose (Figure), except in Nordic Europe, where HbA 1c reductions were similar despite a ∼3-fold difference between groups in BI dose increases from baseline. These results show that the relationship between BI dose increase and HbA 1c reduction can be variable, potentially reflecting regional differences in practices or populations that warrant further analysis.
