For example, almost 80% of respondents from Bulgaria would only initiate insulin therapy in T2D at an HbA1c a threshold of ≥ 9.0% (≥ 75 mmol/mol), of which ~ 95% would not initiate insulin until a threshold of ≥ 10.0% (≥ 86 mmol/mol) was reached, compared to < 15% of prescribers in Slovenia. Here, INS is linked to type 2 diabetes mellitus.
