Modelling the system of health care and drug addicts

Drug addiction is a very intriguing problem all over the world. In Germany about 2-4% of heroin consumers die every year, although a very differentiated care system is established. For this reason the idea comes up that this system is not organized in a proper way. For further analysis of functionality the tools of mathematical systems analysis seems to be appropriate. Quantitative analysis however must be based on sufficient empirical data. With regard to drug care systems there is a lack of adequate data in epidemiology and in care system’s indicators. Several methodological problems and theoretical issues of this study are described in the paper. A global model is proposed based on estimation on regional data of the area of Munich (FRG). The model is built by Stella®. The problems to establish a valid computer-based model are discussed.
