Embodiment Construction

[0014] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the present invention is mainly for individualized prediction of blood-borne infection in patients.

[0016] This method mainly incorporates the data of patients who have undergone blood culture in history from two aspects for model construction, including patient-related disease information, medical intervention-related information, and blood culture results of historical patients.

[0017] The random forest algorithm was used to construct the model and screen out the risk factors related to blood-borne infection.

[0018] Construct predictive models through different methodologies, including regularized logistic regression, K nearest neighbors, support vector machines, random forests, extreme gradient boosting, and deep neural network algorithms.

Abstract

The invention provides an artificial intelligence prediction method for hematogenous infection. The method comprises the following steps: inputting historical data of a patient subjected to blood culture; screening risk factors of infection based on a random forest, and constructing a prediction model through regularization logistic regression, K nearest neighbor, a support vector machine, the random forest, limit gradient lifting and a deep neural network algorithm; and through prediction probabilities of different methods, carrying out secondary learning through a limit gradient lifting algorithm to finally predict whether the patient suffers from hematogenous infection, and further calculating the occurrence probability of the hematogenous infection. The method is used for early warning and advanced medical intervention of blood flow infection possibly existing in an early stage, an existing computer technology is combined and applied to intelligent diagnosis of blood flow infection, and meanwhile, individualized layering of patients with blood-borne infection is realized.

Description

technical field [0001] The invention belongs to the field of judging blood-borne infection, in particular to an artificial intelligence prediction method applied to auxiliary diagnosis of blood-borne infection. Background technique [0002] Bloodstream infections in hospitals are characterized by high morbidity and mortality, among which the mortality rate of bloodstream infections in critically ill patients can be as high as 30%. Numerous studies suggest that early identification and appropriate antibiotic treatment can significantly reduce the incidence and mortality of bloodstream infections. [0003] Clinical studies have shown that the correct rate of physicians in predicting bloodstream infections through clinical experience is very low. In addition, various biomarkers can effectively stop antibiotic treatment, rather than decide whether to start using antibiotics. [0004] In order to give early warning of possible bloodstream infection and advance medical interventi...
