[0047] Embodiment 1 of the present invention: Referring to Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a nursing management method for multiple myeloma patients, comprising:
[0048] S1: Constructing a data fusion platform for multiple myeloma patients, obtaining the medical data of multiple myeloma patients through the data fusion platform, and integrating the medical data through multi-source heterogeneous data sets, wherein the multi-source heterogeneous data sets include completing networking of hospitals in different regions based on the Internet and obtaining data protocols for medical information records from different regions; constructing the data fusion platform for multiple myeloma patients includes connecting the physical characteristic data of multiple myeloma patients to the multiple myeloma patient care management system through an API interface, and standardizing the physical characteristic data of multiple myeloma patients, wherein the standardization includes format conversion of the physical characteristic data of multiple myeloma patients.
[0049] Among them, building a data fusion platform for multiple myeloma patients includes connecting the physical characteristic data of multiple myeloma patients to the multiple myeloma patient care management system through an API interface, and standardizing the physical characteristic data of multiple myeloma patients, and the standardization includes format conversion of the physical characteristic data of multiple myeloma patients;
[0050] The format conversion includes process decomposition of the body feature data and calculation of the standardized function. The formula for calculating the standardized function is: ;in, represents the normalization function, represents the body feature data cleaning function, represents standardized data, and Indicates the field encoding. Represents the encoding normalization function.
[0051] S1.1: Acquiring medical data of multiple myeloma patients includes training a standardized function using a federated learning technique, wherein the training includes training a global model of the standardized function without exchanging the standardized data with external data;
[0052] Combining the process of standardized data and federated learning technology, a standardized data processing flow is constructed, standardized data is used as the input of the federated learning technology, and uploaded to the central server in the processing flow. The central server includes aggregating standardized data, generating local models, and sending the trained global model to each local model to complete the acquisition of medical data of multiple myeloma patients;
[0053] The formula for sending the trained global model to each local model is: ;in, Indicates The global model parameters after rounds of iterations, Indicates The local model is The local model parameters after rounds of iterations, represents the weight coefficient, represents the learning rate, represents the gradient of the loss function, Indicates the number of times.
[0054] Furthermore, during the training process, Hospital A and Hospital B each used local standardized data to train local models. After the training was completed, the parameters of these local models were uploaded to the central server. The central server aggregated the uploaded local model parameters to generate a global model. In the first round of iterations, the central server received the local model parameters of Hospital A and Hospital B, which were recorded as 0.85 for Hospital A and 0.78 for Hospital B, respectively. These parameters were aggregated according to the weight coefficient and learning rate to generate a global model parameter value of 0.82.
[0055] The central server sends the trained global model parameter value of 0.82 to each medical institution. Hospital A and Hospital B continue to train their local models using the new global model parameters. This process is repeated for multiple rounds until the model converges. For example, after the fifth round of iterations, the global model parameter value generated by the central server stabilizes at 0.84, indicating that the model has converged. In this way, each medical institution can jointly improve the performance of the model without sharing the original data, ensuring the efficiency and security of the acquisition and processing of medical data of multiple myeloma patients. The training data is shown in Table 1 below:
[0056] Table 1 Training data display table
[0057] Iteration round Hospital A local model parameters Hospital B local model parameters Central server global model parameters Round 1 0.85 0.78 0.82 Round 2 0.83 0.80 0.82 Round 3 0.84 0.81 0.83 Round 4 0.84 0.82 0.83 Round 5 0.84 0.83 0.84
[0058] As can be seen from Table 1, with the increase in iteration rounds, the local model parameters of Hospital A and Hospital B gradually approach each other, and the global model parameters generated by the central server gradually stabilize. After the fifth round of iteration, the global model parameter value stabilized at 0.84, indicating that the model has converged. This approach enables various medical institutions to jointly improve the performance of the model without sharing the original data, ensuring the efficiency and security of the acquisition and processing of medical data for multiple myeloma patients.
[0059] S1.2: The integration of medical data includes the use of Gaussian mixture models to repair the medical data of multiple myeloma patients. The repair includes the use of Gaussian mixture models GMM to calculate the probability density values of the data points of each local model and the adaptive threshold Make comparisons;
[0060] When the probability density value is less than the threshold When , the local model at this time is abnormal;
[0061] Otherwise, when the probability density value is greater than or equal to the threshold When , the local model is normal;
[0062] The calculation formula for the probability density value is: ;in, represents the probability density value, represents the Gaussian component, represents the mean medical data of multiple myeloma patients, represents the data points of each local model, represents the mixing weight, Indicates the number of times;
[0063] When the local model is abnormal, the interpolation method is used to optimize the abnormal local model. The optimization includes linear interpolation of the data points of the local model before and after the normal local model. The calculation formula of linear interpolation is: ;in, and represents the adjacent normal data points of each local model, and Represents the timestamps corresponding to the adjacent normal data points of each local model, represents linear interpolation, Indicates time.
[0064] Furthermore, the Gaussian mixture model is used to repair the medical data of multiple myeloma patients. Specifically, the probability density value of the data points of each local model is calculated and compared with the adaptive threshold. Assuming that the adaptive threshold is set to 0.05, for a data point of a local model, its probability density value is calculated. For a heart rate data point of patient A of 75 times / minute, the calculated probability density value is 0.04. The calculated probability density value is compared with the adaptive threshold. If the probability density value is less than the threshold, the data point is considered to be an outlier. Since the probability density value 0.04 is less than 0.05, the heart rate data point is determined to be Abnormal value; if the probability density value is greater than or equal to the threshold, the data point is considered to be a normal value. For a heart rate data point of patient B, the heart rate data point is 78 times / minute, and the calculated probability density value is 0.06, so the heart rate data point is determined to be a normal value; when the local model is abnormal, the abnormal local model is optimized by interpolation. For example, for the abnormal heart rate data point of patient A of 75 times / minute, the adjacent normal data points are used for linear interpolation. Assuming that the adjacent normal data points are 78 times / minute and 80 times / minute respectively, the corresponding timestamps are 10:00 and 10:10 respectively, and the new data point obtained by interpolation is 79 times / minute.
[0065] S2: Use the treatment prediction model to pre-process the integrated medical data, and formulate a medical plan for multiple myeloma patients based on the pre-processing results of the medical data.
[0066] Among them, preprocessing the integrated medical data includes training the integrated medical data to generate a treatment prediction model. The formula for training the integrated medical data is: ;in, represents the treatment prediction model, represents the actual observed value, Indicates The feature vector of the samples, Indicates the number of times, Represents model parameters Next pair of samples predictions, represents the loss function, Indicates The actual observed values, represents the training network, represents the model parameters;
[0067] Formulating a medical plan for multiple myeloma patients includes generating a treatment plan for the patient based on the output of the treatment prediction model, and the treatment plan includes treatment effect evaluation, risk assessment and comprehensive assessment;
[0068] when When , the treatment effect evaluation is valid; otherwise, when When , the treatment effect evaluation is invalid, among which, It represents the treatment effect assessment threshold in the multiple myeloma patient care management system;
[0069] when When , the risk assessment is valid; otherwise, The risk assessment is invalid when represents the risk assessment threshold in the multiple myeloma patient care management system;
[0070] when and When , the patient receives treatment according to the treatment plan generated; otherwise, when and When the patient is given a treatment plan, the treatment is abandoned.
[0071] S3: Build an anomaly detection algorithm in the multiple myeloma patient care management system to identify the medical plans formulated by multiple myeloma patients, make intervention recommendations on the medical plans based on the medical treatment decision model, and complete the care management of multiple myeloma patients.
[0072] Among them, building anomaly detection algorithms includes adaptive threshold based Identify the medical plans made by patients with multiple myeloma. The formula for building an anomaly detection algorithm is: ;in, represents the probability density value of each data point, Indicates the constructed anomaly identification period, Indicates critical value;
[0073] When a local model is abnormal and the timestamps corresponding to the adjacent normal data points of each local model are on weekends or holidays, it is marked as a first-level medical abnormality;
[0074] When a local model is abnormal and the timestamps corresponding to the adjacent normal data points of each local model are on a weekday, it is marked as a secondary medical abnormality;
[0075] Recommendations for intervention in the medical plan include notification of the medical plan based on medical anomalies.
[0076] S3.1: Notification of the medical plan includes analysis based on primary and secondary medical anomalies;
[0077] When the multiple myeloma patient care management system detects a level one medical anomaly, the patient is flagged for care through institutional care;
[0078] When the multiple myeloma patient care management system detects a secondary care anomaly, the patient is flagged for care through institutional care or secondary care.
[0079] In a preferred embodiment, a multiple myeloma patient care management system includes an integration module, which constructs a data fusion platform for multiple myeloma patients, obtains medical data of multiple myeloma patients through the data fusion platform, and integrates the medical data through multi-source heterogeneous data sets; a preprocessing module, which uses a treatment prediction model to preprocess the integrated medical data, and formulates a medical plan for multiple myeloma patients based on the preprocessing results of the medical data; a nursing management module, which constructs an anomaly detection algorithm in the multiple myeloma patient care management system, identifies the medical plan formulated by the multiple myeloma patient, makes intervention recommendations on the medical plan according to the medical treatment decision model, and completes the nursing management of multiple myeloma patients.

The personalized treatment plan generated based on the treatment prediction model, combined with the intervention recommendations of the medical treatment decision model, significantly improves the nursing quality and treatment effect of patients with multiple myeloma.
[0083] Embodiment 2 of the present invention: Referring to Figure 1 and Figure 2 , which is the second embodiment of the present invention, provides a multiple myeloma patient care management system and method. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.
[0084] The present invention constructs a data fusion platform for multiple myeloma patients, integrates and repairs medical data using federated learning technology and Gaussian mixture models, generates a treatment prediction model, and formulates a personalized treatment plan based on the model output. Physical characteristic data of multiple myeloma patients, such as hemoglobin level, white blood cell count and heart rate, are obtained from multiple data sources such as hospital electronic medical record systems, laboratory test result systems and wearable devices through API interfaces. These data are standardized, including data cleaning, format conversion and coding normalization. For example, hemoglobin levels are uniformly converted to g / dL, and heart rate data are uniformly converted to times / minute. Federated learning technology is used to train the standardized data to generate a local model. Hospital A and Hospital B use local standardized data to train local models, respectively. The generated local model parameters are 0.85 and 0.78, respectively. The central server aggregates these parameters to generate a global model parameter value of 0.82, and the global model parameters are sent to various medical institutions. After the fifth round of iteration, the global model parameter value is stabilized at 0.84. The Gaussian mixture model is used to train the local model of multiple myeloma. The medical data of myeloma patients were repaired, and the probability density values of the data points of each local model were calculated and compared with the adaptive threshold of 0.05. For a heart rate data point of 75 beats / minute of patient A, the calculated probability density value was 0.04, which was determined to be an abnormal value. The adjacent normal data points of 78 beats / minute and 80 beats / minute were used for linear interpolation, and the new data point obtained by interpolation was 79 beats / minute. The generated treatment prediction model was used to preprocess the integrated medical data, and a treatment plan was generated for the patient based on the model output. For patient A, the treatment effect value predicted by the model was 0.85, and the treatment effect evaluation threshold was 0.7, which determined that the treatment effect evaluation was effective. The treatment risk value predicted by the model was 0.3, and the risk evaluation threshold was 0.5, which determined that the risk evaluation was invalid. Therefore, it was recommended that patient A accept the current treatment plan; on the contrary, for patient B, the treatment effect value predicted by the model was 0.65, which was less than the threshold of 0.7, and the treatment effect evaluation was invalid. The treatment risk value predicted by the model was 0.6, which was greater than the threshold of 0.5, and the risk evaluation was effective. Therefore, it was recommended that patient B consider giving up treatment. The experimental data are shown in Table 2 below:
