Automatic coding method and system for disease diagnosis

Abstract

The invention provides an automatic coding method and system for disease diagnosis, and the method comprises the steps: obtaining a clinical diagnosis result, carrying out the entity recognition and entity relation recognition of the clinical diagnosis result, and marking an entity and an entity type to which the entity belongs; searching associated entities directly associated with the identified entities on the knowledge graph based on the identified entities; searching all candidate standard diagnoses capable of covering entities and associated entities; on the basis of a preset coding rule, searching all possible coding combination results, calculating index coefficients for all the coding combination results, sorting according to the results, and selecting the most suitable result as a final coding result. According to the method, the artificial intelligence technology is utilized, semantic understanding is automatically carried out on clinical diagnosis, and coding is carried out in combination with medical knowledge and ICD coding rules.

Description

technical field [0001] The invention belongs to the technical field of medical coding, in particular to an automatic coding method and system for disease diagnosis. Background technique [0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art. [0003] Medicine is a discipline that studies diseases, so it is inevitable to face a problem, how to accurately identify each disease or disease concept in communication, data exchange and statistical analysis. First of all, it is not feasible to use the name. The name uses language tools to describe a specific concept, which is inevitably affected by the characteristics of the language: cross-language problems, the same disease has different names in different languages; the variety of language expressions Inconsistent names caused by sexual freedom, such as red buttocks and diaper rash, are two expressions of a disease conce...

Problems solved by technology

After a coder receives national training and is issued a certificate of qualification, it often takes several years of work practice to be competent for the coding job. Moreover, because the coding rules only have relatively rough rules of principle, they will not be specific to each disease and each situation. Therefore, in actual work, each coder will derive detailed rules that he thinks are reasonable, which will lead to inconsistent coding of the same disease by different coders
