Biochemical profiling, pharmacological management and clinical outcomes in type 2 diabetes in Danish primary care from 2001 to 2015

      • Massive expansion in type 2 diabetes in primary care from early 2000s to 2015.
      • Improvements in cholesterol levels and antihypertensive and lipid-lowering therapy.
      • Improvements in cardiovascular and mortality outcomes.
      • Conspicuous minority still not receiving diabetes-related medication.



      Primary care plays an integral role in the management of type 2 diabetes (T2D). We investigated in a large group of individuals in this setting the biochemical profiles, pharmacological management and clinical outcomes as well as their changes over time.


      This is a register-based study including relevant laboratory test results requested between 2000 and 2015 by general practitioners in the greater Copenhagen area. We identified 72,044 individuals with T2D on whom data concerning prescription medicine and clinical outcomes were obtained from national registries.


      The number of individuals with T2D greatly increased from 2001 to 2015. Hemoglobin A1c, estimated glomerular filtration rate and urine albumin creatinine ratio did not change, but cholestrol levels improved. The proportion redeeming anti-diabetics remained around 80%, with an increase for metformin. The use of cardiovascular drugs increased. All-cause and especially cardiovascular mortality decreased over the period. Hospital admissions for non-fatal cardiovascular events dropped.


      The number of individuals with T2D in primary care increased dramatically whereas pharmacological management, control of risk factors and clinical outcomes seem to have improved. Nevertheless, a conspicuous minority did not receive diabetes-related medication.
