Diagnoses assignment by ExpertInnen: The number of individuals with diabetes is measured by evaluating the number of persons who had at least one prescription for either insulin or an oral antidiabetic drug. This data was complemented by data of persons who had a hospital stay with the diagnosis diabetes, but didn´t receive any antidiabetic medication. Therefore persons who had at least one prescription for an antidiabetic drug during the period of 2006–2007 and/or persons with a hospitalisation with the diagnosis diabetes are identified as diabetics. Data source is as in ATC-ICD, the GAP-DRG.
