Research And Application Of Data Processing Technology For Hospital Information Comprehensive Platform

The hospital information system is composed of many subsystems,and the data heterogeneity and dispersion are very strong.But along with the policy of drug addition cancellation and reimbursement policy changes,the management of the hospital information system is put forward,then fine unified requirements higher,to integrate all application data,the integrated information platform to achieve a unified.However,the underlying data comes from several different systems,the data structure is inconsistent,it is difficult to unify the acquisition and integration.Therefore,it is necessary to study the data processing technology of information system.The main work of this paper is the research and application of master data design,the research and application of data acquisition technology,the research and application of data processing technology,and the research and application of data storage technology.One data processing technology,including data segmentation,data integration and other technologies.Through the specification of the master index of the master data and the unified definition of the basic information table,the design requirement of the patient centered data center is realized.For different heterogeneous systems,different connection technologies are used to realize the connection of different data sources and data collection.The data collected and stored by the segmentation,normalization and desensitization techniques such as before.The realization method of existing segmentation,select the most suitable medical segmentation reverse maximum matching algorithm for segmentation of data processing.The original data set after segmentation,according to the three kinds of integration specification.Among them,the key work is to research and implement the deletion of duplicate data.The effect of various desensitization methods and the influence on the system performance were analyzed,and the corresponding desensitization rules were formulated to perform the desensitization operation of basic data.Referring to a variety of data storage methods,the timestamp mode is selected to store data,and the solution to the abnormal data in the storage process is proposed.
