Objective: This study aims to describe the routine monitoring of lipids and the use of lipid-lowering medicine in people with type 2 diabetes in the period 2000-2002.
Material and methods: Data from the National Health Service Registry, the Regional laboratory database and the Danish National Hospital Registry have been used for identification and description of known diabetes in a background population of 649,177 citizens in the County of Aarhus, corresponding to 12% of the total Danish population. All data were collected for the period 1 January 2000 to 31 December 2002.
Results: A total of 14,644 people with type 2 diabetes were identified, 52% of whom were men. The mean age was 64 years and the mean duration of diabetes was 7 years. A total of 61% had a minimum of one measurement of total cholesterol in 2000 compared with 64% in 2002. Some 71% of the patients in 2000 compared with 66% in 2002 had a total cholesterol concentration above 5.0 mmol/l. The proportion of people with type 2 diabetes treated with a lipid-lowering drug increased from 15% in 2000 to 24% in 2002. For those who were treated with lipid-lowering medication 33% in 2000 and 42% in 2002 reached currently recommended targets of total cholesterol concentrations.
Conclusions: The results of this study provide a realistic picture of the monitoring of cholesterol as part of diabetes care and found a tendency to increased adherence to guidelines. Even so, it seems as if more patients with diabetes could benefit from treatment with lipid-lowering medication.
