343-OR: Trends in A1C and Lipid Testing, Antilipid Therapy, and Target Attainment following First-Time Glucose-Lowering Drug Treatment in Type 2 Diabetes, Denmark, 2000-2017.

Objective: To examine 18-year trends in early A1C and lipid control among patients initiating first-time glucose-lowering drug therapy (GLD) for type 2 diabetes. Materials and Methods: Population-based sequential cross-sectional study using healthcare databases covering Northern Denmark (∼1.8 million persons). For all 94,175 GLD initiators during 2000-2017, we examined likelihood of A1C and lipid testing, antilipid therapy, and 1-year glycemic and LDL cholesterol target achievement. Results: The proportion of patients with at least one A1C test increased from 53% in 2000 to 95% in 2017 (Figure, Panel A). Lipid testing increased from 82% to 98% and lipid lowering therapy initiation quintupled from 12% to 61%. Mean pre-treatment A1C declined substantially, from 9.2% (77 mmol/mol) to 7.3% (56 mmol/mol) in 2011, then rose to 7.9% (63 mmol/mol) in 2017 (Panel B). Post-treatment A1C decreased less; pre- and post-treatment LDL cholesterol declined similarly. The proportion of patients achieving glycemic and cholesterol targets increased substantially over time (Panel C). Conclusion: Monitoring and treatment of A1C and cholesterol in early type 2 diabetes have improved considerably over the past 18 years, while quality improvement was somewhat flat after the 2011 change in diagnostic criteria.
