title: [Data analysis in health insurance].
abstract: In the last fifty years four to six mathematical research endeavours of general significance only have been designed in the field of health insurance. It is inconsequent to discuss the changes needed in the insurance system without having at one's disposal minimal mathematically-statistically firm basic figures. The present work first generally defines the mathematical bases in the health insurance field. The purpose of the project, within the first large scale data analysis, is above all the development of concepts for the institutionalized, systematic and periodical exploitation of the data available to health insurance carriers and their testing with econometric models. At the same time, thanks to methods to regularly collect data in the various health care sectors, the dependence of cost factors on medical care supply, on the structure of the insured population and on the cost causes will be studied at periodic intervals. Cheap sampling concepts shall be developed and tested in order to obtain the data which are not gathered directly. In a few fields data collection through surveys will be organized in order to allow for comprehensive interdisciplinary interpretation of the data.
