Case data search method, system and device and storage medium

Abstract

The invention discloses a case data search method, system and device and a storage medium. The method mainly comprises the steps of determining a corresponding search mode according to a condition ofdisassembling to-be-searched case data according to medical semantics; selecting a logic operator and a comparison operator according to semantic logic; and forming a logic expression by utilizing thelogic operator and the comparison operator, and searching for the to-be-searched medical record data through the logic expression to obtain a medical record meeting the expectation. According to themethod, a combined search mode of concept search and field search is utilized, the problems that an existing method is single in search granularity and low in search precision and cannot truly restoremedical semantics can be effectively solved, and accurate search results are obtained; and in another aspect, the multi-level comparison operator and the logic operator are combined for use, and a visual graphical interface is matched, so that a flexible and changeable logic expression can be easily presented, the problem of inaccurate search setting caused by complex configuration of logic combination is avoided, and the accuracy of case data search is further improved.

Description

technical field [0001] The invention relates to data retrieval technology, in particular to a case data retrieval method, system, equipment and storage medium. Background technique [0002] With the development and popularization of modern information technologies such as computer technology and network communication technology, most of the current medical institutions have established digital medical information systems to collect and store various medical information in electronic form. Medical workers need to do a lot of medical record search and query work daily, so as to facilitate follow-up related statistical analysis and guide case studies and medical scientific research. In the existing medical record search technology, on the one hand, the hierarchical structure of logical expressions is incomplete, and there are only single-level logical operations such as "and", "or", and "not", or simple numerical comparisons such as "greater than" and "less than". operation. ...

AI Technical Summary

Problems solved by technology

In the existing medical record search technology, on the one hand, the hierarchical structure of logical expressions is incomplete, and there are only single-level logical operations such as "and", "or", and "not", or simple numerical comparisons such as "greater than" and "less than". operation

On the other hand, the granularity of the search is not elastic, which makes the search setting process extremely cumbersome, and the interface is mainly text, which is not user-friendly, resulting in poor accuracy of the final results
