Method and system for intelligent standardization of Chinese disease names based on electronic medical record information

Abstract

The present invention provides a method and system for intelligent standardization of Chinese disease names based on electronic medical record information. The method includes: obtaining electronic medical records to be processed, extracting disease names from the electronic medical records; Probability model to obtain the standardized code corresponding to the disease name; wherein, the generation method of the standardized probability model is: obtain multiple historical electronic medical records, extract the disease name and the disease code corresponding to the disease name from the historical electronic medical records, and generate the disease name and disease A coded mapping list; at least two classification algorithms are selected from preset classification algorithms to establish at least two prediction models, and the data in the disease name and disease coding mapping list are selected to train the at least two prediction models respectively; for at least The two predictive models are model averaged to obtain a standardized probability model. The method can more accurately obtain standardized codes corresponding to disease names in electronic medical records.

Description

technical field [0001] The invention relates to the technical field of intelligent standardization of Chinese disease names based on electronic medical record information, in particular to a method and system for intelligent standardization of Chinese disease names based on electronic medical record information. Background technique [0002] The systematic research on electronic medical records helps us to understand the occurrence and spread of various diseases in the population more systematically, so as to provide help for the improvement of the public health environment. In the study of electronic medical records, the identification of disease names is a very important part. In order to facilitate communication and exchange between regions, the World Health Organization has classified diseases according to their etiology, pathology, clinical manifestations and anatomical location, and formulated a set of internationally unified disease classification methods. Currently, ...

Problems solved by technology

However, in the actual entry of electronic medical records, due to the different naming habits of doctors and the limited input time, the disease names entered by doctors in the system are often inconsistent with the standard disease codes. The communication between medical workers brings too many difficulties, but it will bring great troubles to the researchers of electronic medical records. The main reasons are: the disease coding standards are not completely unified, although medical institutions in my country generally use ICD- 10 code is the basic disease coding system, but different medical institutions often modify and expand the international standard ICD-10 coding system to varying degrees according to their own business needs, resulting in partial disease coding systems in different regions. The case of inconsistent encoding
