Abstract
AIMS
To estimate and compare the prescription costs for the management of patients with diabetes over a period of 20 years in Greece, based on real world data.
METHODS
The records of outpatients with T2D, monitored at three diabetes centres, were examined in four cross-sections (1998, 2006, 2012, 2018). Prescribed medicines per patient, along with a set of clinical indicators were recorded. Annual costs of pharmaceutical treatment per patient were calculated by using each year's nominal retail prices, as well as by adjusting for 2018 price levels, in order to account for price differences over time.
RESULTS
4066 patients were included in the analysis. Prescription patterns indicate a quick uptake of the new classes of glucose-lowering drugs and a reduction in the proportional use of sulfonylurea and glitazone. Adjusting for 2018 prices, the average total annual prescription cost per patient was 381.54 Euros (s.d. 297.44) in 1998 and 1147.21 Euros (s.d. 814.39) in 2018. Glucose-lowering drug costs per patient increase from 1998 onwards, whereas the costs of antihypertensive, antiplatelet and lipid-lowering treatment declined gradually, especially after 2006.
CONCLUSIONS
Per patient prescription costs for glucose-lowering drugs present a steep increase, in Greece over the last 20 years. Real-world evidence studies that compare this increase with the changes in patient outcomes are essential in order to examine whether a costs-vs-outcomes balance is optimal.
