System and method for mining multi-dimensional data of medical information system

Abstract

The invention provides a system and a method for mining multi-dimensional data of a medical information system. The system comprises a plurality of data sources containing information of patients seeing doctors, a knowledge base containing field specific standard, a multi-dimensional data mining warehouse and a data miner, wherein the multifunctional data mining warehouse comprises a dimension table, a fact table and metric values; the dimension table comprises one or more dimensions with logic relations and dimension values; the fact table comprises unified and structured information of all patients seeing doctors listed according to the dimensions; the metric values are statistical values which are obtained through collecting and calculating records of the information of patients seeing doctors in the fact table under the conditions of various dimensions or dimension combinations; and the data miner is used for extracting structured information from the data sources according to the field specific standard and / or extracting the unstructured information and converting the unstructured information into the structured information, thereby establishing the multi-dimensional data mining warehouse. The system can carry out multi-dimensional data mining on clinical information to obtain high quality and structured clinical information.

Description

technical field [0001] The present invention relates to a data mining technology, especially a multi-dimensional data mining system and method used in hospital information systems to extract important statistical data such as disease statistics, seasons of onset, and age of onset, which is beneficial to various medical units and health supervisors. The department realizes scientific decision-making. Background technique [0002] At present, hospitals and other health institutions have made extensive use of digital devices such as computers and new information technologies such as network transmission and online storage in the process of diagnosis and treatment of diseases. Among them, the medical information system, as a system for optimizing the workflow and standardizing the operating procedures of the hospital, has been generally recognized and widely implemented by the majority of medical units. Hospitals include many departments, and the typical work process of a radio...

Problems solved by technology

For the large amount of clinical information accumulated in the hospital, the electronicization of medical records has been realized, which has brought convenience to medical record management and information retrieval. Usually, we use conventional query methods to retrieve information related to a specific patient, or some simple quantitative statistics. Among these large amounts of information, people do not know in advance, but potentially useful knowledge is often ignored

The reasons are, firstly, that in the face of these massive amounts of information, ordinary retrieval methods are inefficient, and even retrieval timeout errors often occur; secondly, conventional statistical queries often obtain some simple statistical results similar to the sum of quantities, It cannot reflect the characteristics of data distribution well, and such statistical results often only have the significance of data statistics, but lack the significance of knowledge mining
