Inadequate treatment of dyslipidemia in people with type 2 diabetes: Quality assessment of diabetes care in a Danish County

Abstract

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.
