Preoperative risk assessment method and system for surgical operation

Abstract

The invention relates to a surgical preoperative risk assessment method and system, and the method comprises the steps: determining main indexes of surgical complication assessment, and forming an index system; establishing a historical data set according to patient historical case data collected by indexes in the index system, and performing data preprocessing on the historical data set; forming a new historical data set according to indexes in the preprocessed historical data set extracted by the feature engineering and other data in the historical data set; establishing a risk prediction model by taking data of the new historical data set as input, various complications in the index system as output and the integrated supervised learning algorithm model as a base model; establishing a case data set; inputting preoperative information in the case data set into the risk prediction model, judging the probability of occurrence of each complication of the patient through the risk prediction model, and comparing the probability with the probability of occurrence of the complication in a clinical surgical operation to form a risk assessment report. The reliability of surgical complication risk assessment can be improved.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine, and in particular relates to a preoperative risk assessment method and system for surgical operations. Background technique [0002] In medical scenarios, the risk assessment of preoperative complications is an important link before surgery, which is directly related to the risk assessment of the surgical process, and is of great significance for surgeons to grasp the surgical process and strengthen the communication between doctors and patients. [0003] Common surgical complications include death, cardiac arrest, myocardial infarction, cerebral hemorrhage, cerebral embolism, cerebral infarction, respiratory failure, pneumonia, ventilator dependence, postoperative low cardiac output, sternal opening, postoperative thrombosis, Intracranial infection, increased intracranial pressure, cerebral hernia, pulmonary embolism, deep vein thrombosis of lower extremities, anastomotic leakage, surg...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned problems such as poor reliability in the risk assessment of surgical complications in the prior art, and provides a preoperative risk assessment method and system for surgical operations, which are used to perform preoperative risk assessments for surgical operations, and predict whether patients are about to The risk probability value of complications during or after surgery provides a reference for doctors to control the surgical process and preoperative doctor-patient communication
