Description

Technical Field

[0001] The present invention relates to the technical field of medical prescription drug screening, and in particular to a method and system for screening and sorting main therapeutic drugs in medical prescriptions. Background Art

[0002] Electronic medical records contain a comprehensive, detailed, timely and accurate description of individual patient health information, and contain a wealth of information and knowledge. Through in-depth analysis and mining of information in electronic medical records, a large amount of medical knowledge closely related to patients can be obtained, which can then be used to build clinical decision support systems and provide personalized health information services. For example, the core content of current medical artificial intelligence research is to recommend corresponding clinical diagnosis and treatment decision support based on changes in the condition of hospitalized patients at different time points based on electronic medical records.

[0003] When learning the doctor's prescription medication based on the electronic medical record, the drugs are obtained from the patient's hospitalization prescription. However, the medication in the prescription is all the drug information according to the doctor's condition during the patient's hospitalization, including functional medications, auxiliary medications, temporary medications and other types of drugs. Therefore, each patient will have several types of drug information during hospitalization or before each change in condition. If the model includes all drugs in the learning and recommendation, the complexity and difficulty of the model learning will be greatly increased due to the large number of labels, and thus a high prediction accuracy cannot be achieved.

[0020] Embodiment 1:

[0021] Figure 1 1 is a flow chart of a method for screening and sorting the main treatment drugs in a doctor's prescription provided according to an embodiment of the present invention. Figure 1 As shown, the method specifically comprises the following steps:

[0022] Step S102, identifying and screening the medical prescription and medication information of the target medical record to obtain the medical prescription and medication set of the target medical record.

[0023] In the embodiment of the present invention, the target medical record is an electronic medical record, and the target medical record includes hospitalization medical order information. The hospitalization medical order information is the doctor's instructions to the patient on diet, medication, laboratory tests, etc. according to the patient's condition and treatment needs during hospitalization, including three categories: long-term medical order, temporary medical order, and standby medical order. The medical order medication set is a set of medicines in the hospitalization medical order information.

[0024] Step S104, calculating the weight value of each drug in the set of prescribed medications under the admission diagnosis of the target medical record.

[0025] Specifically, the weight value of each drug under the corresponding admission diagnosis is calculated by the following formula:

[0026] IMPT NB =log(p(x i =1|y j =1))-log(p(x i =1|y j =0));

[0027] Among them, IMPT NB is the weight value, log(p(x i =1|y j =1)) is the diagnosis of admission y j Conditional drugs x i The logarithmic probability value, log(p(x i =1|y j =0)) means no admission diagnosis y j Conditional drugs x i The logarithmic probability value of . Among them, i and j are the drug number and admission diagnosis number respectively.

[0028] Step S106, based on the weight value, screen out the drugs that are main treatment drugs in the set of prescribed drugs to obtain the set of main treatment drugs.

[0029] Step S108, sorting the drugs in the main therapeutic drug set based on the weight values.

[0030] The present invention provides a method for screening and sorting the main therapeutic drugs in medical orders, which can identify and screen the medical order medication information in medical records, and further screen out the main therapeutic drugs according to the weight value of the drugs to the admission diagnosis, and can rank the importance of the drugs according to the correlation between the drugs and the admission diagnosis, so as to achieve accurate recommendation of drugs for diagnosis and treatment plans, and alleviate the technical problem of low accuracy of recommendation of main therapeutic drugs in the prior art.

[0031] Optionally, step S102 specifically includes the following steps:

[0032] Step S1021, identifying the medical prescription medication information of the target medical record, obtaining all the drugs related to the medical prescription medication information, and obtaining a first drug set;

[0033] Step S1022, screening out drugs whose prescription type is temporary prescription and drugs whose drug category is non-primary therapeutic drugs in the first drug set, to obtain a second drug set; non-primary therapeutic drugs include auxiliary drugs and supportive treatment drugs; wherein the drug category can be obtained from a preset drug knowledge base;

[0034] Step S1023, in the second drug set, the drugs with a medication frequency less than or equal to a preset frequency or a medication duration less than or equal to a preset duration are screened out to obtain a set of prescribed medications. For example, drugs with a medication frequency less than or equal to 1 time and a medication duration less than or equal to 3 days are screened out, wherein the preset medication frequency and the preset medication duration are determined according to medical expert advice or statistical methods.

[0035] In an embodiment of the present invention, through the method in the above steps S1021-S1023, the medical prescription medication information in the medical record can be preliminarily screened, and non-primary therapeutic drugs can be determined by category, which can reduce the complexity of subsequent screening and help improve the accuracy of subsequent screening.

[0036] Specifically, step S106 also includes the following steps:

[0037] Step S1061, screening out drugs with weight values ​​less than a preset threshold value from the set of prescribed drugs to obtain a third drug set, and screening out drugs with weight values ​​greater than or equal to the preset threshold value to obtain a fourth drug set;

[0038] Step S1062, screening out drugs whose drug indications are consistent with the admission diagnosis of the target medical record from the third drug set, to obtain a fifth drug set; wherein the drug indications can be obtained by calling a preset drug knowledge base;

[0039] Step S1063, taking the sum of the fourth drug set and the fifth drug set as the main treatment drug set.

[0040] In an embodiment of the present invention, for the screening process of the main therapeutic drugs in the doctor's order, the drugs in the doctor's order drug set are first divided into a main treatment drug set (i.e., the fourth drug set) and a screened drug set (i.e., the third drug set) according to a preset threshold, and then from the screened drug set, it is checked whether the indication of each drug is consistent with the admission diagnosis of the target medical record, and then the consistent drug set (i.e., the fifth drug set) is also divided into the main treatment drug set, that is, the fifth drug set is merged with the fourth drug set to obtain the final main therapeutic drug set.

[0041] Optionally, sorting the drugs in the main therapeutic drug set includes: sorting the drugs in the main therapeutic drug set in descending order according to corresponding weight values.

[0042] From the above description, it can be seen that an embodiment of the present invention provides a method for screening and ranking the main therapeutic drugs in medical orders. By screening and ranking the drugs based on the weight values ​​of the drugs related to the admission diagnosis, a set of main therapeutic drugs in the medical orders ranked by relative importance can be obtained, so that the diagnosis and treatment plan based on this method can achieve more accurate prediction and evaluation indicators based on relative importance, alleviating the technical problem of low accuracy of recommendation of main therapeutic drugs in the prior art.
