[0035] S10. Collect medical treatment data samples and build a medical database.

[0036] Medical treatment data samples are collected from multiple channels such as electronic health record systems, medical literature databases, and public health data platforms. Data cleaning and standardization techniques are used to remove noise and inconsistencies in the samples, ensure data quality, and form a structured medical database.

[0037] S20. Extract sample feature keywords from the medical database.

[0038] Assume that the number of samples in the medical database is n. For each sample i, extract sample feature description keywords based on the given features. Each sample has m features. The m feature attributes include disease category, disease cause, disease symptoms, allergy history, diagnosis results, treatment plan, treatment cost, reason for successful cure, reason for failed cure, etc. There are j feature description keywords extracted from each feature.

[0039] The above extraction process is repeated to extract all the feature description keywords of n samples and store them in set S.

[0040] S30. Train a customized treatment plan model based on sample characteristics and test cases. The model outputs a customized treatment plan and gives a predicted trend of treatment effect.

[0041] Training a customized treatment plan model is divided into the following sub-steps:

[0042] S31. Communicate with patients and summarize test cases and treatment influencing factors.

[0043] Before building a customized treatment plan model, you first need to communicate with the patient and record the communication content to form a test case.

[0044] Treatment influencing factors include communication feature vector, medical history feature vector, and physical factor feature vector.

[0045] Communication between patients and doctors. Good communication can improve treatment compliance and effectiveness. The characteristics of communication can be obtained through the frequency and content of communication. The specific formula is C i ={c i1 , c i2 , c i3}, where Ci represents the communication feature vector of the i-th patient, c i1 Indicates the communication frequency, c i2 Indicates the communication method. Different communication methods will affect the effect of information transmission. i3 Indicates the content of communication.

[0046] The patient's medical history is crucial to the choice of treatment plan. The specific formula is E i ={e i1 , e i2 , e i3 , e i4}, where E i represents the medical history feature vector of the i-th patient, e i1 Indicates previous diseases, diseases the patient has suffered from in the past and their treatment, e i2 Indicates family medical history, including hereditary diseases, infectious diseases, e i3 Indicates surgical history, the patient's past surgical experience and its results.

[0048] S32. Extract test case features, match the test case features with features of a sample set in a database, and form a feature group.

[0049] Use the formula extracted in step S20 to extract the features of the test case. Suppose the number of test case features that are not empty after extraction is k, k≤m, and the feature set of the test case is f k , the keyword set of the test case is

If any feature of the test case does not exist in a certain sample, the indicator function δ = 0, and the sample does not enter the feature population set R; if any feature of the test case exists in a certain sample, the indicator function δ = 1, and the sample enters the feature population set R.

[0051] S33. Match the samples that are most similar to the test case features in the feature group set to form a historical sample set, so as to find the corresponding treatment plan set.

[0055] S34. Prioritize the treatment plans in the treatment plan set.

[0056] Perform keyword matching on samples in the historical sample set. The higher the keyword matching score of the sample, the higher the priority of its treatment plan. Define the matching score function Score to calculate the sample keyword matching score.

[0061] The above replacement formula is repeated until y options are replaced, and the optimized treatment plan p'1, that is, the customized treatment plan, is obtained.

[0062] S36. Calculate the predicted trend of treatment effect based on treatment influencing factors.

The specific formula for the actual treatment trend is T i ={t i1 , t i2 , t i3}, T i represents the actual treatment trend feature vector of the i-th patient, t i1 Indicates the changes in the patient's symptoms during treatment, t i2 Indicates the change of inspection indicators, t i3 Indicates changes in patients' quality of life.

[0066] The customized treatment plan is adjusted according to the predicted trend of treatment effect and the actual treatment trend. The specific formula is: Among them, P adjust For the adjusted customized treatment plan, L phase Indicates the treatment stage, including the initial treatment stage and the stable treatment stage, comparison (T i ,P actual ) is used to compare the actual treatment trend T i and treatment effect prediction trend P actual The result value of the deviation is different according to the treatment stage. The threshold of the deviation between the actual treatment trend and the predicted trend of the treatment effect is different. If the deviation exceeds the threshold V threshold , you need to use the replacement formula Replace and adjust the treatment plan to obtain better treatment effect.
