[Follow up of the CoDiM-Study: Cost of diabetes mellitus 2000-2009].

Cost of illness studies create transparency on the economic dimension of diseases. By now, the CoDiM study, based on administrative data of AOK Hesse und KV Hesse, identifies costs of people with diabetes and diabetes related excess costs in Germany for a period of 10 years. To date, additionally adjusted results are available by accounting for effects caused by inflation and ageing of the population. From 2000 to 2009 the number of treated patients with diabetes increased by 49 %, adjusted for age by 31 %. Mean cost of patients with diabetes and diabetes related excess costs per capita turned out to be relatively stable over the time period observed. The relation of cost per patient with diabetes to cost of patients without diabetes didn't change. Due to the increase of the number of treated patients with diabetes in the past 10 years, the total direct cost, dependant on the approach of calculation (adjusting or not for inflation and ageing effects), rose by 28 % to 70 %, the therein included diabetes excess cost by 24 % to 61 %. © Georg Thieme Verlag KG Stuttgart · New York.
