One third of patients with diabetes in Austria discontinue treatment

A research team led by the Complexity Science Hub Vienna and the Medical University of Vienna has analysed the actual prevalence of Type 2 diabetes in Austria for the first time as part of a study. In addition to identifying clear regional differences, an alarming and previously unknown figure came to light: one in three people suddenly stop treatment and go without medication and/or medical check-ups for at least a year. And, as the study also showed, this group had a higher mortality rate than patients with diabetes who regularly access the care available to them. The results have just been published in the latest edition of Scientific Reports.

Until now, data on the prevalence of diabetes in Austria had been based on estimates or surveys. But now, the first ever nationwide scientific study on the incidence of diabetes has pinpointed the exact number of patients who received medication (antihyperglycaemic) and/or underwent medical monitoring of blood glucose levels (HbA1c) between 2012 and 2017. And the process brought to light a group whose size was previously unknown: of the 746,184 patients analysed, some 268,680 – more women (140,960) than men – discontinued treatment and/or monitoring of the disease for at least one year. For this group, the researchers were also able to demonstrate a significantly higher mortality rate.

"Although neither the cause of mortality among members of this subgroup is known, nor has a causal link between discontinued treatment and mortality been proven, from a clinical perspective we cannot rule out some kind of connection," principal investigator Alexandra Kautzky-Willer from MedUni Vienna's Department of Medicine III. Especially among patients with diabetes, a willingness to undergo treatment has a key role to play if they are to avoid serious complications such as cardiovascular disease, kidney failure, loss of sight or neuropathy to the fullest extent possible.


The researchers obtained the study results by analysing the nationwide data on services rendered, which is collected by the Dachverband der Sozialversicherungsträger, the umbrella organisation of social insurance institutions in Austria. "We developed a new epidemiological diabetes progression model to enable us to identify patients with diabetes who have stopped or temporarily interrupted their treatment," noted principal investigator Peter Klimek from the Complexity Science Hub Vienna.


In addition to revealing trends relating to the incidence of diabetes, this new procedure also uncovered considerable regional differences in Austria, which were broken down at a district level for the first time. The incidence map confirms the east-west divide identified in previous studies – showing that the highest rates were found in north-eastern Austria and in Bruck/Leitha in particular – but also reveals new diabetes clusters in the west (districts of Imst and Schwaz as well as Innsbruck Stadt). "As much attention needs to be paid to these new clusters as the large number of patients who break off their diabetes treatment," said Alexandra Kautzky-Willer in conclusion. The reasons why patients stop or temporarily interrupt therapy are to be researched in further studies so that targeted countermeasures can be taken.




The study “Obesity as pleiotropic risk state for metabolic and mental health throughout life” has been published in Translational Psychiatry.




The mission of the Complexity Science Hub (CSH Vienna) is to host, educate, and inspire complex systems scientists dedicated to making sense of Big Data to boost science and society. Scientists at the Complexity Science Hub develop methods for the scientific, quantitative, and predictive understanding of complex systems.

The CSH Vienna is a joint initiative of AIT Austrian Institute of Technology, Central European University CEU, Danube University Krems, Graz University of Technology, Medical University of Vienna, TU Wien, VetMedUni Vienna, Vienna University of Economics and Business, and Austrian Economic Chambers (WKO).



The Medical University of Vienna (in short: MedUni Vienna) is one of the most traditional medical education and research facilities in Europe. With around 8,000 students, it is currently the largest medical training centre in the German-speaking world. With 6,000 employees, 30 departments and two clinical institutes, 13 medical theory centres and numerous highly specialised laboratories, it is one of Europe's leading research establishments in the biomedical sector. MedUni Vienna also has a medical history museum, the Josephinum.
