Problems solved by technology

[0002] In the current medical practice, the data presented subjectively by the patient needs to be recorded by the doctor. This is the medical record. However, in the busy clinic environment, there are many difficulties in the accuracy, completeness and economy of asking the medical history.
According to research statistics, doctors at the grassroots level can only implement 59% of the medical history data collected by asking patients, and 41% of the questions fail to ask patients, and doctors spend 20% of their time in outpatient practice Consumed in the production of medical records, so diagnosis and treatment records are very important in clinical work, high cost, but difficult to be effective, complete or accurate
If the complete medical record mechanism cannot be improved, it will be impossible to provide communication between the doctor and the patient and clarify the evolution of the disease and the complexity of the health status, and there will be hidden misunderstandings in the medical care of critically ill patients between different specialties, resulting in duplication of treatment or conflicts situation, reducing the quality of care

Embodiment 1

[0033] like figure 1 Shown, a kind of chief complaint in medical record and symptom matching method in history of present illness, described method carries out the following steps:

[0034] Step 1: Obtain the chief complaint text, and perform text extraction on orientation, body part, description and symptoms in the chief complaint text; then extract more detailed symptoms according to the template of "position + body part + descriptive + symptom" and record them Information for each subsection;

[0035] Step 2: Divide the text of the history of present illness into blocks, and then take the method of step 1 to extract and split the symptoms in the text for the content of each block;

[0036] Step 3: When comparing the symptoms in the chief complaint with the symptoms in the current medical history, according to the template of "location + body part + descriptive + symptoms", first match whether the content of the body part and the symptoms are consistent; if the symptoms are...

Embodiment 2

[0041] On the basis of the previous embodiment, the method for satisfying that the character string similarity is greater than the set threshold and the interval span is less than the set threshold, that is, determined to be consistent, performs the following steps:

[0042] Use the following formula to calculate whether the string similarity is greater than the set threshold, and whether the string similarity is smaller than the set threshold:

[0043]

[0044] range len =range-com_lenran ;

[0045] The com_len is to obtain the length of the common part, and min_len is to compare the length of the shorter text in this article. The common part matched by the symptoms in the chief complaint and the history of present illness may not be continuous, so range refers to the text matched by the history of present illness from The interval length from the beginning of the common part to the end of the common part, threshold sim Is the similarity threshold, threshold ran is the ...

Embodiment 3

[0051] On the basis of the previous embodiment, the method of obtaining the chief complaint text and performing text extraction on the orientation, body parts, description and symptoms respectively in the chief complaint text performs the following steps:

[0052] Using the double-array Trie tree structure established based on the correct word dictionary and the typo word dictionary, the maximum matching method is used to accurately segment the Chinese sentence, and the precise word segmentation graph is established, and the results of the precise segmentation based on the typo word dictionary are analyzed. mark, and the correct word corresponding to the typo word matching of the Chinese sentence and the typo word dictionary is added to the word graph simultaneously, comprising the following steps:

[0053] Establish the double array Trie tree structure DicTrie of correct word dictionary;

[0054] Set up the double array Trie tree structure TypoDicTrie: (TypoWord, CorrectWord)...

Abstract

The embodiment of the present invention proposes a method for matching chief complaints in medical records and symptoms in current medical history, which relates to the technical field of medical information technology. The present invention adopts the string matching of the self-defined template combined with the matching of the word vector at the semantic level. When searching for the corresponding part from the symptom to the history of present illness in the main complaint, the method based on the longest common subsequence algorithm plus restriction rules is adopted to improve the system. Effect.

Description

technical field [0001] The invention relates to the technical field of medical information technology, in particular to a method for matching chief complaints in medical records and symptoms in current medical history. Background technique [0002] In the current medical practice, the data presented subjectively by the patient needs to be recorded by the physician. . According to research statistics, doctors at the grassroots level can only implement 59% of the medical history data collected by asking patients, and 41% of the questions fail to ask patients, and doctors spend 20% of their time in outpatient practice It is spent on making medical records, so diagnosis and treatment records are very important and costly in clinical work, but they are difficult to be effective, complete or accurate. If the complete medical record mechanism cannot be improved, it will be impossible to provide communication between the doctor and the patient and clarify the evolution of the dise...
