Problems solved by technology

[0003] At present, doctors usually judge that the patient's pneumonia is not easy or easy to turn into severe or critical by interpreting the patient's chest X-ray. However, manual interpretation is less efficient and has greater subjectivity, which can easily lead to misjudgment

Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] In the clinical management of COVID-19 issued by the World Health Organization, the clinical range of COVID-19 pneumonia includes mild, moderate, severe and critical. As mentioned in the background technology, for some mild and moderate patients with new coronary pneumonia, some of them will develop into severe and critical, and the fatality rate of severe and critical patients with new coronary pneumonia is quite high. Therefore,...

Abstract

The invention mainly discloses a method and device for generating a prediction model for predicting pneumonia severity. The method comprises the following steps: acquiring clinical information of a subject; acquiring image information of the subject; screening N features out from clinical information and image information, wherein N is a natural number; constructing a corresponding classificationmodel by taking at least one of the N features as an input and the pneumonia severity as an output; training corresponding classification models by taking the N features of the plurality of subjects as training samples, and determining the classification model with the optimal fitting precision and parameter number in the plurality of classification models as the prediction model based on a presetcriterion. By adopting the scheme provided by the invention, the prediction model with low model complexity and high prediction accuracy is generated.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method and device for generating a prediction model for predicting the severity of pneumonia, computer equipment, and a computer-readable storage medium. Background technique [0002] Novel coronavirus pneumonia (COVID-19, Corona Virus Disease 2019, COVID-19), referred to as "new coronary pneumonia". The clinical spectrum of COVID-19 includes mild, moderate, severe and critical. At present, for patients infected with new coronavirus pneumonia, mild and moderate patients account for about 40% each, severe patients account for about 15%, and critical patients account for about 5%. Among mild and moderate patients, some patients will develop into severe and critical. According to the latest report from the Chinese Center for Disease Control and Prevention, the overall case fatality rate of COVID-19 is 2.3%, while that of severe and critical cases is 49.0%. Therefore, i...
