AI Technical Summary

Technical Problem

When predicting the incidence of allogeneic blood transfusion during perioperative joint replacement in elderly patients, existing technologies fail to fully consider factors such as patient age and comorbidities, resulting in inaccurate prediction results and inability to rationally plan blood use.

Method used

By selecting potential factors from patients' historical clinical information and using univariate and multivariate regression models for analysis, relevant and independent risk factors were screened out. Combined with allogeneic blood transfusion assessment indicators, a prediction model was established to calculate the incidence of allogeneic blood transfusion.

Benefits of technology

It improves the prediction accuracy of the incidence of allogeneic blood transfusion, provides a reasonable blood use plan, and helps patients recover faster after surgery.

Abstract

The invention discloses a method and system for predicting the occurrence rate of allogeneic blood transfusion in the joint replacement perioperative period of an elderly patient, and belongs to the technical field of medical data processing, and the method comprises the steps: selecting potential factors from the historical clinical information of the patient; related factors are obtained by analyzing the influence degree of the potential factors on blood transfusion indications in the perioperative period of joint replacement; performing control variable analysis on the potential factors to screen out independent risk factors; in combination with related factors and independent risk factors, allogeneic blood transfusion evaluation indexes are obtained; and calculating an allogenic blood transfusion incidence prediction value of the target patient according to the allogenic blood transfusion evaluation index through a preset allogenic blood transfusion incidence prediction model. Therefore, by implementing the method and the device, the problem that in the prior art, other factors possibly causing the allogenic transfusion risk of the elderly patient are not considered, so that the calculated allogenic transfusion occurrence rate is inaccurate or the prediction time is too late, and reasonable blood use planning for the perioperative period of the patient cannot be realized can be solved.
