APPLICATION OF CLASSIFICATION MODELS BY DATA MINING AND INFORMATION TECHNOLOGY FOR ANALYZE THE RESULTS OF TREATMENT OF CARDIAC AND DIABETIC PATIENTS
Introduction. In recent years, the scientific community, especially in the medical field, has been putting a lot of efforts and resources into the development of eHealth technologies and systems. Various methods of intellectual support, which are necessary to ensure high quality of medical care, have been developed. The study of the effectiveness of the application of various methods of diagnosis, treatment of patients and restoration of their health is one of the important components of the assessment of the quality of medical care.
The purpose of the paper is to analyze the results of providing medical care with the use of developed models based on Data Mining methods to identify factors that affect the results of treatment.
The results. A method of estimating the medical care results using Data Mining methods has been developed, the feature of which is the combination of filtering algorithms, clustering and classification methods. Models of the medical care result depending on significant factors were built. To test the developed method, a retrospective analysis was carried out using a database of hospital patients of various departments of clinical facilities. The distribution of treatment results evaluation (according to the standardized formulation) of cardiac and diabetic patients was obtained, and concomitant diseases and complications were analyzed. A model for determining the factors influencing the treatment outcome, based on the decision tree method (CART), has been developed. Analysis of the decision tree structure makes it possible to draw conclusions about the decision-making logic by a specific doctor. With the help of decision tree models, the relationship between complications, the main diagnosis and other factors, in particular, concomitant diagnoses, recurrence of hospitalization etc., was analyzed.
Conclusions. The combination of statistical methods and the developed method and models based on Data Mining (a decision tree calculated according to the CART algorithm and 10-fold cross-validation) for analysis of medical hospital databases made it possible to identify the frequency characteristics of concomitant diseases and complications typical for cardiac and diabetic patients, and also allowed to determine the main factors that depend on the decision-making by doctors about the outcome of treatment.
