AIMS Aim of the present study is to compare control of hyperglycaemia and other diabetes-related cardiovascular risk factors during the years 1998 and 2006 and to estimate the change in the cost of medications prescribed for this purpose. METHODS We compared the medical records of all patients who were regularly followed in three major diabetes centers located in Athens and Piraeus, Greece, during 1998, with those who were examined at the same centers during 2006. The cost of medications was calculated in Euros per patient-year (euroPY), using the 2006 official Greek market prices. RESULTS A total of 1 743 eligible files were included in the study (805 files from 1998 and 938 from 2006). HbA (1c), LDL-cholesterol and blood pressure improved significantly in 2006 as compared to 1998 (7.0% vs. 8.1%, 2.9 mmol/l vs. 3.9 mmol/l and 134.9/77.6 mmHg vs. 139.3/80.9 mmHg respectively, p<0.001 for all comparisons). Treatment of hyperglycaemia was more intense and had a different pattern in 2006. The proportion of patients receiving antihypertensive, hypolipidaemic and antiplatelet drugs increased from 48.8% to 74.4%, from 15.2% to 61.2% and from 17.6% to 51.1% respectively (p<0.001 for all comparisons). A highly significant increase in the cost per patient-year was observed for all classes of medications in 2006. The total cost of all diabetes-related medications increased in 2006 by 221.1% (from 341.3+/-276.0 euroPY to 1095.8+/-634.1 euroPY). CONCLUSIONS Control of cardiovascular risk factors of patients with T2D, regularly followed by diabetes specialists, improved significantly in 2006 as compared to 1998. This improvement, however, was associated with a considerable increase in the cost of medications prescribed for treatment of these parameters.
