Abstract (eng)
The International Diabetes Federation (IDF) estimates 246 million patients with diabetes worldwide and places a prognosis of 380 million affected in 2050. In Europe from 22,5 million adults (WHO) to 33,3 million adults (IDF) suffer from diabetes. The Austrian Diabetes Report (2004) estimates 300.000 patients, and the “Diabetes Forum Austria” 400.000 patients in Austria. The cost of diabetes mellitus accounts for approximately 6% of the total health care expenditures in western counties.
To represent the incidence of type-2 diabetes in an economic model, the lives of 10.000 patients were simulated, passing eleven health states. The markov monte-carlo model reflects reality in an appropriate way, which indicates a well working model. In comparison to standard care, incidence rates reduced for each health state with comprehensive care. Life expectancy after the diagnosis of diabetes mellitus type-2 as well as the patient’s age at death had a positive effect under comprehensive care.
The purpose of the cost-effectiveness-analysis was to compare two competing treatments (standard- versus comparative care). The properties of the treatments have been fixed by the DCCT (Diabetes Control and Complications Trial) in 1997. Target of the trial was an HbA1c < 7%. Costs for the model have been taken over from existing studies from Austria and Germany. Utilities have been taken over on the one hand, and on the other hand they had to be estimated.
The results of the cost-effectiveness-analysis have been discounted at 0%, 3%, 5%, and 7,5% rates, whereas the focus lies on the results at 3% discounting rate. CER (Incremental Cost/QALY) is ~24.000 Euros (0%), ~35.000 Euros (3%), ~41.000 Euros (5%) and ~43.000 Euros (7,5%). All results are in the cost-effective range of below 50.000 Euros/QALY
