Problems solved by technology

At this time, it is difficult to control the influence of the related diseases of these comorbid diseases on the measurement of the complexity of the symptoms of the attending disease in scientific research. If the related comorbid variables are controlled and the patients with these comorbid diseases are deleted, then the number of cohort samples of the sick population will be reduced. will be greatly reduced and lack diversity

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, a symptom complexity calculation method based on electronic medical record data includes the following steps:

[0031] a. Establish symptom characteristics: obtain the patient's symptoms, duration, and identification ID from the database, and correspond the symptoms and duration to the corresponding patient according to the patient's identification ID; for example, the electronic medical record database of depression patients, in this database Extract the main complaint information of the patient cohort admitted for depression, that is, the patient's symptoms, duration, and identification ID.

[0032] b. Symptom pretreatment: make statistics on the symptoms, establish the patient's disea...

Abstract

The invention relates to the field of electronic medical records, and discloses an electronic medical record data-based symptom complexity calculation method. The method comprises the following steps: a, establishing symptom characteristics: acquiring symptoms, duration and identifiers (ID) of patients from a database, and enabling the symptoms and the duration to correspond to the corresponding patients according to the identifiers (ID) of the patients; b, symptom preprocessing: performing statistics on symptoms, establishing a symptom matrix of the patient, and outputting the symptom matrix after preprocessing; c, symptom complexity calculation: calculating a symptom probability in the preprocessed symptom matrix and a duration probability corresponding to the symptom, and constructing a symptom complexity calculation formula of the patient according to the symptom probability and the duration probability. According to the method, on the basis of a whole disease research all-crowd queue, the relationship between symptoms and duration is proposed, the current symptoms are converted into vectors on the basis of expressions of all symptoms of crowds in the current queue, and the complexity and severity of the symptoms are obtained.

Description

technical field [0001] The invention relates to the field of electronic medical records, in particular to a method for calculating symptom complexity based on electronic medical record data. Background technique [0002] Electronic medical records are a kind of medical records that are stored, managed, transmitted and copied by medical staff using digital information such as text, symbols, charts, graphics, data, and images generated by the information system of medical institutions in the course of medical activities. [0003] There are a lot of texts in the electronic medical records to describe the patient's symptoms, but it is possible that when a patient is currently admitted to the hospital, he is often accompanied by multiple diseases and comorbidities. Diabetes, high blood pressure and other non-indication diseases. At this time, it is difficult to control the influence of the related diseases of these comorbid diseases on the measurement of the complexity of the sy...
