Data Mining In Medical Information Systems Research And Application

With the rapid development of database technology and the diversification of the means for people to obtain the data,Human data have increased dramatically With large capacity, high speed, low cost storage devices one after another,increasing the capacity of the current database has reached TB, or PB levels. But most of the data is stored in the operation as a general data been used,but not really reflect the history,the value of vast amounts of data.To be able to get hidden behind huge amounts of data in the value of knowledge with decision-making, data mining came into being,Using this technology a lot of data from some in the mining knowledge hidden in them, so as to provide people with valuable scientific information in order for business managers or other decision makers with information for reference and decision support, and ultimately makes Enterprise management and scientific and economic benefits maximized.After decades of rapid development of data mining technologies used to produce fruitful results in theory and application. As an application of a strong discipline, data mining technology has penetrated into all fields of national economy, academia and industry caused great concern on a wide range of applications for all walks of life provide a valuable management decision making. For the domestic data mining research is still in its infancy, its application was only concentrated in some large industries (such as: telecommunications, insurance, finance, etc.), data mining in terms of medical information, research and application of the foreign country is also relatively more in foreign aid not only the data mining in medical clinics, but also in widely used in the management of patients and hospitals. Therefore, the data mining research in the medical industry in China has important practical value. Based on the study, based on data mining technology, combined with the hospital information management system, carried out based on association rules mining medical data analysis and research, the main contents include: 1,according to the actual application needs of the HIS data analysis to determine the dimensions required for excavation analysis and summary. Hospital information system established for the data warehouse, based on actual demand and to establish the corresponding fact table and dimension table to determine particle size, the use of multi-dimensional analysis of the data required for data preparation operations, through data integration and data as the data collected after cleaning The data source. 2,the data mining Apriori association rules algorithm analysis and optimization, the use of these algorithms to data mining of patient data. 3,gallstone patients by hospital stay and cost analysis of the situation, the establishment of special diseases cost analysis model, look for the impact of hospital costs in patients with gallstones factors, cost data to achieve its internal structure of medical understanding and prediction. The correlation results can provide reference for the reasonable control of costs, while increasing the health insurance institutions to manage staff efficiency and management level.
