Embodiment Construction

[0061] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0062] In view of considering the economic and time benefits of index collection, the goal of the present invention is to use as few indexes as possible to obtain relatively good prediction results. In order to achieve such a goal, in the present invention, we will try to use a variety of machine learning algorithms, apply each algorithm to calculate separately with different index numbers, and conduct scientific evaluation on the results, in order to obtain the application of machine learning for hospital fatal digestive tract O...

Abstract

The invention provides an intelligent screening method for critical indexes of predicting fatal gastrointestinal rebleeding in a hospital, and the method comprises the following steps: extracting index data of a patient suffering from gastrointestinal hemorrhage from a database according to an inclusion exclusion standard, and calculating an outcome identifier; performing data cleaning on the index data to process abnormal values, and removing redundant indexes and indexes of which missing values are serious and cannot be analyzed; discretizing the index data according to a discretization standard set according to a clinical actual situation; taking the discretized index data as a condition attribute, and taking an outcome identifier as a decision attribute; inputting the condition attributes and the decision attributes into a screening algorithm model, calculating fitness, iteratively repeating until the fitness is not increased any more and the indexes are not reduced any more, and obtaining screened key index data. The method can efficiently and stably calculate the key index for indicating that the patient suffering from gastrointestinal hemorrhage suffers from hospital fatal rebleeding, and assists a doctor in making a decision.

Description

technical field [0001] The invention relates to the technical field of evolutionary calculation, in particular to an intelligent screening method for key indicators for predicting fatal gastrointestinal rebleeding in a hospital. Background technique [0002] Gastrointestinal bleeding is a common symptom in emergency clinics, and its etiology is complex. It can be caused by diseases of the digestive tract itself, such as gastric ulcer, acute gastric mucosal lesion, vascular lesion, tumor, or mechanical injury, as well as by adjacent organ lesions and systemic disease. Disease involving the digestive tract. When patients with gastrointestinal bleeding receive treatment in medical institutions, one of the important goals is to prevent fatal rebleeding in the hospital, because once a patient has an occult fatal rebleeding of the gastrointestinal tract or a short-term uncontrollable hemorrhage, and the resulting suffocation or blood loss Sexual shock is often the main cause of i...
