Healthcare costs of Type 2 diabetes in Germany

AimTo describe for the first time the direct costs of Type 2 diabetes treatment by analysing nationwide routine data from statutory health insurance in Germany. MethodsThis cost-of-illness-study was based on a 6.8% random sample of all German people with statutory health insurance (4.3 out of 70 million people). The healthcare expenses show direct per capita costs from the payer perspective. Healthcare expenses for physicians, dentists, pharmacies, hospitals, sick benefits and other healthcare costs were considered. Per capita costs, cost ratios for people with Type 2 diabetes and without diabetes as well as diabetes-attributable costs were calculated. ResultsPer capita costs for people with Type 2 diabetes amounted to Euro4,957 in 2009 and Euro5,146 in 2010. People with Type 2 diabetes had 1.7-fold higher health expenses than people without diabetes. The largest differences in health expenses were found for prescribed medication from pharmacies (cost ratio diabetes/no diabetes: 2.2) and inpatient treatment (1.8). Ten percent of the total statutory health insurance expense, in total Euro16.1 billion, was attributable to the medical care of people with Type 2 diabetes. ConclusionsThis nationwide study indicates that one in 10 Euros of healthcare expenses is spent on people with Type 2 diabetes in Germany. In the future, national statutory health insurance data can be used to quantify time trends of costs in the healthcare system.
