For example, it cannot verify the rationality of excessive dosage or special solvents, and has a high false alarm rate, such as directly judging drugs used with caution as unreasonable. Furthermore, it cannot proactively optimize and iterate intelligent tools in multiple dimensions, resulting in poor reliability of proactive monitoring and poor proactive optimization and iteration effects in drug prescription data monitoring and evaluation. Summary of the Invention

[0006] Preferably, when collecting original medication data from the medical institution's information system and third-party verified data stored on the blockchain, the following information is collected: drug name, single dose, solvent type, route of administration, and prescription timestamp; patient pathological characteristics are collected through the electronic medical record system; and full lifecycle data of the drug, including drug batch number, solvent compliance certificate, and manufacturer qualifications, are obtained through the alliance link interface.
[0007] Preferably, when constructing a standardized data matrix with trusted label values using dual-source verification data sequences, the row index of the data matrix is designed to be a single prescription, and the data is arranged in ascending order by prescription timestamp; The column index is a feature variable, including basic features, verification features, and trusted label values.

Furthermore, the clinical intervention necessity score P is obtained through calculation, and the clinical intervention necessity score is set as the element value. The relevant expression is as follows: Where XB is the trusted label value.
[0011] Preferably, the trusted label value, medication risk index, and rule fit are analyzed using a joint model, and the joint analysis value LF is output; wherein, the expression of the joint model is: ;in, These are the trusted label threshold, the medication risk threshold, and the rule adaptation threshold, respectively.

Attached Figure Description
[0019] The invention will now be further described with reference to the accompanying drawings.
[0020] Figure 1 This is a flowchart illustrating the operation of the AI-based drug data monitoring and evaluation system of this invention. Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figure 1 As shown, this invention is an artificial intelligence-based drug use data monitoring and evaluation system, comprising: Multi-source data acquisition and processing module: Acquires and preprocesses multi-source data, constructs a dual-source verification data sequence, and uses the dual-source verification data sequence to construct a standardized data matrix with trusted label values. The dual-source verification data sequence includes original medication data from the medical institution's information system and third-party verification data stored on the blockchain. Specific steps include: When collecting raw medication data from medical institution information systems and third-party verified data stored on the blockchain, data is collected in real time through standardized interfaces of Hospital Information System (HIS), Laboratory Information System (LIS), and Electronic Medical Record System (EMR). Specifically, this includes: Collect drug name, single dose, solvent type, route of administration, and prescription timestamp through the hospital information system; The drug name includes the generic name and brand name, such as sodium penicillin for injection (North China Pharmaceutical); the unit for a single dose is mg / vial, accurate to one decimal place; the solvent type is such as 0.9% sodium chloride injection; the route of administration is such as intravenous infusion, oral administration, or intramuscular injection; the prescription timestamp format is YYYY-MM-DD-HH-MM-SS, specifically corresponding to year-month-day-hour-minute-second; The patient's pathological characteristics are collected through the electronic medical record system (EMR), including but not limited to patient identification, age, liver and kidney function indicators, and allergy history; liver and kidney function indicators include but are not limited to alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum creatinine (Cr), and blood urea nitrogen (BUN). Among them, the reference ranges for liver and kidney function indicators are marked according to the "Normal Reference Values for Clinical Laboratory Results". For example, the normal range for alanine aminotransferase (ALT) is 0-40 U / L. In addition, the entire lifecycle data of a drug can be obtained through the alliance link interface, including the drug batch number, solvent compliance certificate, and manufacturer qualifications. The entire lifecycle data of a drug is automatically synchronized to the local system through smart contracts. Among them, the batch number corresponds to a 20-digit code; the solvent compliance certificate corresponds to the drug regulatory authority's filing number; and the manufacturer's qualification corresponds to the GMP certification status. In addition, blockchain data comes with its own timestamps and hash values, and only the hash digest is retained when stored locally to avoid leakage of the original data; When preprocessing the collected multi-source data, including but not limited to timestamp alignment, hash value comparison and tamper detection, and outlier identification and processing, outlier identification and processing can be implemented based on the improved Z-score algorithm. These are all existing conventional technical solutions, and the specific implementation steps are not elaborated here. The preprocessed multi-source data is sorted and combined to obtain a dual-source verification data sequence. When constructing a standardized data matrix with trusted label values using dual-source verified data sequences, the row index of the data matrix is designed to be a single prescription, and the data is sorted in ascending order by prescription timestamp; The column index is a feature variable, including basic features, verification features, and trusted label values; Among them, the basic features include drug name code, standardized dose value, and solvent type code; Verification features include timestamp alignment results, hash comparison results, and outlier flags. The trust label value, ranging from 0 to 100, is calculated by comprehensively considering data integrity, tamper-proof nature, absence of outliers, and matching with blockchain data. The higher the trust label value, the higher the trustworthiness. When calculating the trust label value, for data integrity, 30 points are awarded for no missing fields, and 10 points are deducted for each missing key field, such as dosage and solvent. For tamper-proof hash comparisons, a match results in 20 points, while a mismatch results in 0 points. For cases without outliers, 30 points are awarded when flag=0 and 0 points are awarded when flag=1. For blockchain data matching, 20 points are awarded for timestamp alignment and batch compliance, 10 points are awarded for timestamp alignment but batch non-compliance, and 0 points are awarded for timestamp misalignment and batch non-compliance. Example: For a prescription, data completeness is 30 points, tamper-proof is 20 points, no outliers are 30 points, and blockchain matching is 20 points. The trustworthy label value = 30 + 20 + 30 + 20 = 100 points; data with a score of 80 or above is considered highly reliable. When standardizing the constructed data matrix, continuous variables are standardized using the Min-Max method, such as dose and liver and kidney function indicators. And perform one-heat encoding on categorical variables to obtain a standardized data matrix; where categorical variables include, for example, solvent type; Example: 0.9% sodium chloride is coded as [1,0,0], and 5% glucose is coded as [0,1,0]. The standardization process is carried out using existing conventional technical means, and the specific implementation steps will not be elaborated here.
[0023] In this embodiment of the invention, cross-validation between the medical institution system and blockchain data can solve the problem of easy tampering of single-source data in traditional systems, effectively improving data reliability; the trusted label values in the standardized matrix can provide clear input for subsequent risk assessment, avoid low-quality data interfering with the assessment results, and effectively improve the system's autonomous optimization efficiency.
[0024] The 3D evaluation tensor processing module calculates dynamic evaluation indicators based on a standardized data matrix. These indicators include a medication risk index and rule fit. A 3D evaluation tensor is then constructed using these dynamic indicators. Specific steps include: When calculating the medication risk index based on a standardized data matrix, the formula is used. The calculation results are as follows: RI is the medication risk index; a, b, and c are all weighting coefficients, a+b+c=1, with default values of a=0.4, b=0.3, and c=0.3, which can be customized according to actual clinical needs; D is the dose deviation; S is the solvent risk level value; and P is the patient pathological fit. Among them, the dose deviation degree D is the proportion of the deviation between the actual dose and the disease-specific routine dosage threshold table in the dynamic rule base, which reflects the rationality of the dose; If the actual dose is less than or equal to the lower limit of the threshold, the dose deviation D = 0.2; If the lower limit of the threshold is less than the actual dose and less than or equal to the upper limit of the threshold, the dose deviation D = 0.5; If the actual dose is greater than the upper threshold, the dose deviation D = actual dose / upper threshold. Example of parameters: In the dynamic rule base, the upper limit of the conventional threshold for penicillin in adult community-acquired pneumonia is 1200mg. If the actual standardized dose for a certain patient is 1500mg, then D=1500 / 1200=1.25; If the actual dose is 800mg, which is between the lower threshold of 500mg and the upper threshold of 1200mg, then D=0.5; The solvent risk level value S ranges from 0 to 5, where 0 indicates no risk and 5 indicates incompatible substances. Specifically, the basic risk level of the drug-solvent combination can be directly read from the compatibility matrix. For example, the basic risk level of penicillin plus 5% glucose is 2. When adjusting for liver and kidney function indicators, if the patient's creatinine is >133μmol / L, corresponding to renal insufficiency, the risk level is increased by 1 when the solvent is a "potassium-containing solution". For example, the risk level of the solvent is 3 after the base level of 2 is adjusted. Example parameters: If the patient has normal renal function and the prescription is penicillin plus 0.9% sodium chloride, the base level of the compatibility matrix is 0, then S=0; if the patient has renal insufficiency and the solvent is 10% potassium chloride solution, the base level is 3, and the corrected solvent risk level value S=4. The patient pathological fit P is the degree of matching between the patient's pathological characteristics and the drug warning level, which is calculated by summing the allergy history matching degree, age stratification fit degree, and complication correlation degree. Specifically, regarding the allergy history matching score, if the patient's allergy history list overlaps with the drug's contraindicated ingredients, the corresponding value is 1; if there is no overlap, the value is 0. Regarding age-stratified suitability, the value is 1 for children and elderly patients using adult doses, and 0 for age-stratified doses. Regarding the correlation with complications, if the drug instructions clearly state that a complication should be used with caution, the corresponding value is 1; if there are no complications, the value is 0. When calculating rule fit based on a standardized data matrix, a set of rules related to the current disease and drug is extracted from the rule base, including clinical guideline rules and historical best prescription rules. Among them, clinical guidelines, such as the "maximum daily dose of penicillin ≤4000mg" in the "National Guidelines for Antimicrobial Therapy"; Historical best prescription rules, prescription characteristics of the same disease that have been "passed without intervention" in the past 3 months, such as solvent selection preference and dose fluctuation range; Obtain several target vectors from a standardized data matrix. These target vectors specifically represent dosage, solvent, route of administration, and pathological suitability. Calculate the feature vector distance using weighted cosine similarity, and then apply the formula... Calculate the rule fit FA; where DX is the feature vector distance. , where i is the feature dimension index, corresponding to 4 target vectors; Let be the weighting coefficient for the i-th feature. The values corresponding to dosage, solvent, route of administration, and pathological suitability are 0.3, 0.2, 0.2, and 0.3, respectively, satisfying the following condition: ; This is the i-th feature vector component of the current prescription, with specific values ranging from: dose [0,2]; solvent [0,5]; route of administration [0,1]; and pathological suitability [0,1]. For the i-th feature vector component of the optimal prescription in the dynamic rule base, based on historical risk-free prescriptions and predefined values from clinical guidelines, the value range is [missing information]. Consistent; When integrating the confidence label value, medication risk index RI, and rule fit FA to construct a three-dimensional evaluation tensor, the confidence level of the data corresponding to the X-axis is set to 0-100 points, with an interval of 10 points, and divided into 10 intervals; for example, [80,90) and [90,100]. The Y-axis represents the drug application risk index: 0-5 points, with intervals of 0.5 points, divided into 10 intervals; for example, [0,0.5), [0.5,1.0]. Z-axis rule fit: 0-100 points, with 10-point intervals, divided into 10 intervals; for example, [70, 80), [80, 90); Furthermore, the clinical intervention necessity score P is obtained through calculation, and the clinical intervention necessity score is set as the element value. The relevant expression is as follows: Where XB is the confidence label value; the higher the clinical intervention necessity score, the lower the intervention necessity; when the clinical intervention necessity score is <5, manual review is automatically triggered. When performing tensor visualization and storage, it is displayed in the form of a 3D heatmap, with red areas corresponding to low scores, indicating high-risk prescriptions; and green areas corresponding to high scores, indicating low-risk prescriptions. Tensor data is stored in CSV format, containing coordinates (X,Y,Z) and corresponding clinical intervention necessity scores, supporting clinical retrospective analysis.
[0025] In this embodiment of the invention, by weighted integration of multiple dimensions of factors such as dosage, solvent, and pathology, the risk of medication can be quantified, which can effectively improve the accuracy of identifying unconventional dosages and contraindicated solvents. Compared with traditional single-threshold judgment, it can effectively reduce the false judgment rate. The matching degree algorithm based on historical best prescriptions and real-time guideline updates enables the system to dynamically adapt to clinical changes, which can effectively improve the adaptation speed to new diseases. By constructing a three-dimensional assessment tensor, complex data can be transformed into intuitive scores, reducing unnecessary intervention for low-risk prescriptions and realizing risk visualization and graded intervention.
[0026] The joint judgment dynamic grading optimization module: Based on the three-dimensional evaluation tensor, it performs joint analysis and judgment on the credible label value, medication risk index, and rule fit; if the result is a judgment failure, it triggers the grading optimization mechanism and optimizes the implementation of the existing regulatory assessment scheme; the specific steps include: The trusted label value, medication risk index, and rule fit are analyzed using a joint model, and the joint analysis value LF is output. The expression of the joint model is as follows: ;in, These are the trusted label threshold, the medication risk threshold, and the rule adaptation threshold, which can be determined based on data such as the "Medical Institution Data Quality Specification" or by combining the application requirements of the actual application scenario with expert consensus. The specific values are not limited. If the joint analysis value is 0, the result is considered passed; If the joint analysis value is 1, the test is deemed unsuccessful and a hierarchical optimization mechanism is triggered. When implementing a tiered optimization mechanism, if If so, data credibility optimization is performed, and the reasons for low credibility are located through the sub-dimensions of the credibility label value. These sub-dimensions include, for example, patient information completeness and drug code matching accuracy. Reasons for low credibility include, for example, the drug specification not being filled in, resulting in a code matching accuracy of 60%. When the backup data source is enabled, a pop-up interactive interface prompts pharmacists to manually enter missing information, such as drug specifications and solvent volume, and then the trusted label value is recalculated after the missing information is added. If the missing data is a functional test indicator, the latest test results will be automatically obtained by calling the hospital's LIS system interface; like Then, the weight parameters of the rule base are updated through reinforcement learning algorithms to optimize the risk assessment model; Reinforcement learning is a type of machine learning method that uses an agent to interact with the environment and continuously try and optimize decision-making strategies based on reward signals. Its core objective is to enable the agent to learn to take a series of actions in a specific environment in order to maximize long-term cumulative rewards. The weight parameters of the rule base updated by the reinforcement learning algorithm are existing conventional techniques, and the specific implementation steps will not be elaborated here.
[0027] In this embodiment of the invention, by jointly analyzing and judging the trust label value, medication risk index, and rule adaptability, and dynamically triggering a hierarchical optimization mechanism based on the judgment results, the implementation of the existing regulatory assessment scheme is proactively optimized and managed, thereby improving the proactive optimization effect of the implementation of the existing regulatory assessment scheme.
[0028] Multi-dimensional implementation effect evaluation and management module: Conducts multi-dimensional regulatory analysis on the implementation effect of existing regulatory evaluation schemes, proactively evaluates the implementation effect of existing regulatory evaluation schemes in corresponding local and overall dimensions, and implements targeted closed-loop iterative management; closed-loop iterative management includes local closed-loop iterative management and overall closed-loop iterative management.
[0029] When conducting multi-dimensional regulatory analysis, the total number of first-level regulatory actions N1 and the total number of second-level regulatory actions N2 that trigger the hierarchical optimization mechanism are statistically analyzed using the first iterative identification model, and the first iterative identification value DS1 is output. Similarly, the total number of second-level regulatory actions is analyzed using the second iterative identification model, and the second iterative identification value DS2 is output. The expression for the first iterative recognition model is: Where K is the optimization trigger threshold; a is a natural number greater than 0; The expression for the second-iteration recognition model is: Where N0 is the optimization implementation threshold; b is a natural number greater than 0; the optimization trigger threshold and the optimization implementation threshold can be determined based on the test simulation data in the early stage of the application of the regulatory assessment scheme, or they can be customized in combination with the application requirements and specifications of the actual application scenario; A joint analysis is performed on the first and second iteration identification values. If both values are 0, the existing regulatory assessment scheme will continue to be implemented. If a value 'a' exists, then implement targeted overall closed-loop iterative management. If a value b exists, targeted local closed-loop iterative management is implemented. Specifically, local closed-loop iterative management involves iteratively upgrading the hierarchical optimization mechanism; overall closed-loop iterative management involves iteratively upgrading both the existing regulatory assessment scheme and the hierarchical optimization mechanism. The specific content and rules of different iterative upgrades can be determined according to the application requirements and specifications of the actual application scenario, and this embodiment of the invention does not impose specific limitations. By analyzing data and implementing targeted local closed-loop iterative management and overall closed-loop iterative management, the reliability of the existing drug use data regulatory assessment scheme and the reliability of the self-optimization scheme are further improved.
[0030] Unlike existing technical solutions that only focus on single-dimensional regulatory optimization without analyzing and iteratively managing the implementation and optimization effects from different dimensions, this invention analyzes the implementation effects of existing regulatory assessment schemes from multiple dimensions. It proactively evaluates the implementation effects of existing regulatory assessment schemes in both local and overall dimensions, and implements targeted closed-loop iterative management. This extends and expands existing regulatory assessment schemes and optimizations, ensuring the reliability of existing regulatory assessment schemes and the diversity of regulation from different dimensions.
