Melnyk K. Method and models of information screening of medical documentation in decision support systems with ambiguous information

The purpose of the dissertation research is to improve the quality of decision-making information by developing the method and models of information screening of medical records. Main results: the method of information screening of medical documentation was first proposed, which, in comparison to existing methods, takes into account the ambiguity of medical information which allows improving the quality of information and decision-making efficiency for early diagnosis of diseases; models for assessing the health and risk of disease development have been improved by identifying the semantic component in medical records, which allows to determine the need of diagnostic procedures and, as the result, to reveal signs of the disease development at early stages; the model for planning of screening activities in a medical facility was further developed by designing the individual course of screening activities and selecting a set of patients for their implementation based on semantic processing of medical records, which allows increasing the efficiency of temporary, financial and human resources for the implementation of therapeutic and prophylactic measures; the information technology of decision support in the medical facility has been further developed by using the method of information screening of medical documentation that allows to determine the risks of the development of diseases at an early stage.
