Description of the research topic:

The escalating growth of electronic information in the field of healthcare puts a spotlight on the retrospective clinical trials. Processing of large amount data with traditional statistical methods is not always effective, or it is sometimes limited to implementation constraints. Data mining, including its specialized fields such as network analysis and process mining, is one of the most important tools for discovering patterns from large data sets. However, due to the unique nature of the health care and the complexity of the human biological system, for efficient analysis in the healthcare domain, data mining methods can only be used after area specific extensions. The improved and healthcare-adapted data mining algorithms can effectively contribute to the analysis of retrospective clinical trials, and they can provide a basis to explore the influencing factors affecting the human biology system. This new knowledge helps physicians achieve individualized medicine. The aim of the research is to develop such new healthcare-adapted data mining methods and algorithms which can effectively contribute to the exploration of information from large
healthcare datasets. The effectiveness of the suggested methods should be presented in real case studies. The research includes the following topics: development of new control group selection methods for case-control trials; analyzing the effect of control group selection methods on the analysis outcome; exploration of complex connection systems of independent
and confounding variables and the analysis of their effects on healing processes. Suggested methods should be evaluated by medical experts.
