ATC-ICD
ATC-ICD is a two step statistical technique. In step 1, based on hospital and sick leave diagnoses and medication received by the insured and co-insured persons over a defined period of time) assignment probabilities to diagnoses were calculated. In step 2, these assignment probabilities are applied to the prescription data of all persons who have used social insurance services, which anables an estimate of diseases probabilities to be made. The calculations are based on the GAP-DRG 2006/2007: The GAP-DRG (Grundlagenforschung für ambulante, personenbezogene „Diagnoses related Groups“) is a research database of the Association of Austrian Social Security Institutions that is used for the development of methods (method: ATC-ICD). It contains reimbursement data of all social health insurance funds as well as the diagnostic data of hospital admissions and sick leaves for the years 2006 and 2007.
Expert Assignment
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.
ATHIS (Austrian Health Interview Survey)
The Austrian Health Interview Survey 2006/2007 questioned a representative sample of about 15,000 Austrian residents aged 15 years and over They were asked inter alia if they ever had diabetes and subsequently if they therefore received treatment or antidiabetic medication within the past 12 months. The results obtained were extrapolated to the whole Austrian population. This resulted in two variants: ATHIS_Jemals and ATHIS_Behandlung.
Result Number
