Problems solved by technology

[0003] Although domestic and foreign guidelines have prediction thresholds for blood transfusion, they only determine whether to start a high-dose blood transfusion plan, and do not provide guidance on the refinement of red blood cell transfusion in trauma treatment, nor clarify how much blood can be transfused to achieve relative safety. threshold

Embodiment Construction

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] The purpose of the present invention is to invent an intelligent auxiliary software system for diagnosis and treatment of trauma blood transfusion by studying the correlation between pre-transfusion demand assessment and post-transfusion curative effect evaluation of trauma patients, so as to provide accurate and rapid blood transfusion decision-making opinions for bleeding treatment of trauma patients.

Abstract

The invention provides a method for establishing a trauma blood transfusion prediction model. The method comprises steps of obtaining historical trauma patient blood transfusion related data as a historical user data set; acquiring original features from the historical user data set; training the original features by using a gradient boosting decision tree algorithm to obtain corresponding combined features or reconstructed new features; and extracting a characteristic parameter set suitable for representing the blood transfusion volume of a single user from a plurality of characteristics according to the distribution characteristics, related characteristics and importance of the combined characteristics or the new characteristics to train a blood transfusion prediction model. The method is advantaged in that the mode that a doctor performs empirical blood transfusion only through descriptive test results can be achieved, the success rate of patient treatment is increased, the death rate is reduced, and blood resources are saved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for establishing a traumatic blood transfusion prediction model and a method and system for determining the amount of blood transfusion. Background technique [0002] Traumatic injuries account for about 10% of global deaths, 80% of operating room deaths and 50% of deaths within 24 hours after trauma are related to bleeding. Uncontrolled bleeding is the leading cause of potentially preventable death in trauma patients. The 24-hour mortality rate and 30-day mortality rate of blood transfusion patients before admission were significantly lower than those of non-blood transfusion patients in the control group. Early administration of blood products in the early stage of trauma, shortening the time of pre-hospital transfer, early admission to hospital for medical intervention, and reasonable blood transfusion are important measures to reduce mortality. Early assessment of...
