Problems solved by technology

[0008] However, the above-mentioned schemes have the following problems: the pre-processes of schemes 1 and 2 are too complicated, and for ordinary case systems, it is acceptable to establish word vector models and knowledge graphs
[0009] In summary, the existing solutions for general medical case retrieval have certain defects, and are not suitable for ICU case retrieval. There is an urgent need for a solution that is specific to the characteristics of ICU cases while ensuring retrieval accuracy and speed while consuming less resources. retrieval system

Embodiment 1

[0082]image 3 In order to be an application scenario of the ICU similar case retrieval method of the embodiment of the present invention. The clinician can check the data during the hospital, select one or several medical character indicators, select one or several medical characteristics, generate the ICU similar case search result set, and the result set can be used as a research topic. use. Specific steps are as follows:

[0083]Structuring the input text, the input text is unstructured data, and the S101 to S104 in the first step 1 needs to perform steps in the step 1, the input text is converted to: "Medical Features: Feature Attributes".

[0084]Follow Step 2 Retrieving the ICU case of the input text in the case search system, a total of S ICU cases can be obtained, and S is positive integer.

[0085]According to step 3, the degree of matching of each medical feature in the S ICU case is scored, and n score is obtained.

[0086]Weighted the fraction of all medical features, and obtain the...

Embodiment 2

[0088]Figure 4 In order to be another application scenario of the ICU similar case retrieval method of the embodiment of the present invention. During the treatment, the clinician selection the early warning category of the patient, during which the patient physiological index and warning are detected, when the warning triggered, according to the conditions triggered by the warning, and from the patient to the ICU to this moment, in the case retrieval system Match similar ICU cases, doctors see the treatment and development of these historical ICU cases. Specific steps are as follows:

[0089]In this embodiment, the text is the warning information, which is structured data, and only the S103, S104 step in the first step 1, and the input text is converted to: "Medical Features: Feature Attributes" performance form.

[0090]Follow Step 2 Retrieving the ICU case of the input text in the case search system, a total of S ICU cases can be obtained, and S is positive integer.

[0091]According to s...

Abstract

The invention discloses an ICU similar case retrieval method based on similarity calculation. The method comprises the steps: obtaining an input text, analyzing the input text, and obtaining medical features included in the input text and feature attributes corresponding to the medical features; performing retrieval in a case retrieval system based on each medical feature included in the input text, and obtaining historical ICU cases matched with feature attributes of the medical features; for each historical ICU case, scoring the matching degree of each matched medical feature according to a similarity calculation mode corresponding to the type of each matched medical feature; performing weighted summation on the scores of all the medical features matched in the historical ICU case to obtain a total score of the historical ICU case; and sorting the historical ICU cases according to the total scores of the historical ICU cases to obtain and output an ICU case retrieval result set. According to the invention, high-precision and high-efficiency retrieval of ICU cases is realized.

Description

Technical field[0001]The present invention relates to the field of data processing, and more particularly to an ICU similar case retrieval method and system based on similarity calculation.Background technique[0002]With the informationization process of medical and health services, large medical institutions such as hospitals and medical examinations have produced a lot of medical electronic health records. The data content is mainly from the electronic medical record of the hospital, containing a large number of non-structured / semi-structural data. Case queries based on patient similarity can become a doctor's technical supplement, and doctors can perform preliminary diagnosis of patients according to this technology. The patient's similarity can also be applied to many areas such as patient group identification and patient risk leveling.[0003]Compared with ordinary cases, ICU cases has more, more complex feature data. For example, there is a large number of medication informatio...
