[0002] In the current medical context, chronic diseases have become a major global health challenge. Existing chronic disease management primarily relies on patients seeking medical attention after experiencing discomfort or on device alarms based on fixed thresholds. However, these existing solutions suffer from significant delays and low accuracy, often only issuing warnings and taking action after an acute event has already occurred or symptoms are very pronounced, missing the optimal intervention window. Furthermore, fixed threshold alarms cannot adapt to individual physiological differences and dynamic changes; different users may have different sensitive alarm thresholds, resulting in a high false alarm rate and undoubtedly increasing the workload of relevant personnel.

Figure 2 The method shown can be applied to Figure 1 In the system shown, the method may include the following implementation steps: S201. Obtain multi-source fusion data, which is used to characterize multi-source data of potential acute events of users.
[0031] The multi-source fusion data mentioned above in this application can refer to relevant data used to analyze the impact of users on acute events. This data may include, but is not limited to, the user's heart rate time series data, heart rate variability (HRB) time series data, activity level time series data, weight time series data, sleep time series data, heart rate and pulse time series data, respiration time series data, blood pressure time series data, user medical history data, medication record data, environmental data (e.g., PM2.5), or other data used to analyze the impact of users on acute events.

For example, this application can first acquire the user's multi-source symptom data. This application also does not limit the implementation method for acquiring the aforementioned multi-source symptom data. For example, relevant data for analyzing the impact of acute events on the user can be acquired from other devices (such as web servers, wearable devices, or other terminal devices) through application programming interfaces or related communication protocols. This data may include, but is not limited to, the user's historical medical records, historical medical records, weight time-series data, heart rate time-series data, heart rate variability (RHV) time-series data, sleep time-series data, activity time-series data, environmental monitoring data, etc. This application does not impose further limitations or details on this. Next, this application can preprocess the acquired multi-source symptom data, such as performing timestamp alignment, standard conversion processing to a unified format, or other custom data processing on each data point in the multi-source symptom data, thereby obtaining preprocessed multi-source symptom data. Optionally, this application can also perform time-series anomaly detection on each data point in the multi-source symptom data, discarding or supplementing data with time-series anomalies, etc. This application does not impose further limitations or details on this. Finally, this application can fuse the preprocessed multi-source disease data together to form a unified vector or matrix representation of the multi-source fused data, which facilitates subsequent processing.
[0033] The acute events mentioned above in this application can refer to clinical events requiring emergency medical intervention when a user suffers from a chronic disease but is induced by emotional instability or other factors. These acute events may include, but are not limited to, acute events of the cardiovascular system, respiratory system, metabolic system, or other systems. Specifically, acute events of the cardiovascular system may include, but are not limited to, acute decompensated events of heart failure, such as fluid retention, abnormal heart rate or rhythm, or other acute cardiovascular events; or risk events for acute coronary syndrome, such as a significant decrease in heart rate variability, the appearance of specific arrhythmia patterns, etc., which this application does not further limit or elaborate on.

[0034] S202. Based on the preset physiological baseline model, multi-level feature extraction is performed on the multi-source fusion data to obtain corresponding multi-level feature data. The physiological baseline model is obtained in advance through unsupervised learning based on historical multi-source disease data and multi-level disease features.
[0035] The physiological baseline model described in this application is a pre-defined model set by the system according to actual conditions. It can be used to perform a series of analyses and processing on the multi-source fusion data of the user experiencing acute events. The model may include, but is not limited to, self-coded decoding models or other supervised learning models. Different physiological baseline models can be designed for different users. These models can be obtained by unsupervised learning and training based on the user's historical multi-source disease data and multi-layered disease characteristics. This application does not impose further limitations or details on this.
[0036] This application does not limit the specific implementation of the above-mentioned multi-level feature extraction. Taking three-level feature extraction as an example, the above-mentioned multi-level feature data may specifically include first-level feature data, second-level feature data, and third-level feature data. In specific implementation, this application can first perform first-level feature extraction on the above-mentioned multi-source fusion data to obtain the corresponding first-level feature data. The above-mentioned first-level feature data can be used to reflect the user's physiological abnormal data. In specific implementation, taking the above-mentioned multi-source fusion data including heart rate variability (HRV) time series data, activity time series data, and weight time series data as an example, this application can reconstruct the target data based on the above-mentioned physiological baseline model. For example, the target data can be encoded and then decoded using the physiological baseline model to obtain the corresponding target reconstructed data. Then, the reconstruction error is calculated on the target data and the target reconstructed data to obtain the corresponding abnormal error value, which can also be called the abnormal score. This application does not limit the specific implementation of the above-mentioned reconstruction error calculation. For example, the mean square error can be calculated on the target data and the target reconstructed data. For example, the mean square error between the target data and its corresponding reconstructed data at each time point can be calculated. This application does not limit or elaborate on this. The target data mentioned above can be the HRV time-series data, the activity level time-series data, or the weight time-series data. When the target data is the HRV time-series data, its corresponding anomaly error value can be specifically referred to as the HRB anomaly error value HRV_Anomaly_Score; when the target data is the activity level time-series data, its corresponding anomaly error value can be specifically referred to as the activity level anomaly error value Activity_Anomaly_Score; when the target data is the weight time-series data, its corresponding anomaly error value can be specifically referred to as the weight anomaly error value Weight_Anomaly_Score. This application does not impose further limitations on this. After obtaining the anomaly error values corresponding to the three target data, this application can use these three anomaly error values, specifically HRV_Anomaly_Score, Activity_Anomaly_Score, and Weight_Anomaly_Score, as the aforementioned first-level feature data. This application does not impose further limitations or details on this.
[0037] Next, this application can perform secondary feature extraction on the aforementioned multi-source fusion data to obtain corresponding secondary feature data. This secondary feature data can specifically be used to reflect user behavior and environmental risk data, and may include, but is not limited to, user sleep efficiency, medication deviation rate, environmental PM2.5 values, or other feature data reflecting user behavior and environmental risk. This application can also perform tertiary feature extraction on the aforementioned multi-source fusion data to obtain corresponding tertiary feature data. This tertiary feature data can specifically be used to reflect the user's static clinical background data, and may include, but is not limited to, user complication data, past acute illness history or attack history, or other data describing the user's clinical condition background, etc., which this application does not limit or elaborate on further.
[0038] S203. Calculate the AERS value and probability of occurrence of the acute event based on the multi-level feature data to obtain the AERS value and probability of occurrence of the acute event.
[0039] This application does not limit the specific implementation method of the above-mentioned AERS value calculation. For example, this application can perform weighted calculation on the above-mentioned first-level feature data, the above-mentioned second-level feature data, and the above-mentioned third-level feature data based on a preset AERS formula to obtain the corresponding AERS value. The specific calculation of the above-mentioned AERS formula can be shown in the following formula (1): Formula (1) In this context, α, β, and γ are the corresponding weighting coefficients, which can be pre-defined by the system according to actual conditions. Typically, their sum is 1, and this application does not impose further limitations or details. T1, T2, and T3 represent the processing scores corresponding to the first-level, second-level, and third-level feature data, respectively. These processing scores are obtained by the system through customized processing based on actual needs; for example, their values can range from 0 to 100, and this application does not impose further limitations or details. These processing scores, to a certain extent, reflect the contribution of the corresponding level of feature data to the prediction of acute events in users. In practical applications, the AERS values can be positively correlated with the first-level, second-level, and third-level feature data, respectively, and this application does not impose further limitations or details.
[0040] This application does not limit the specific implementation method for calculating the probability of occurrence of the above-mentioned acute events. For example, this application can perform regression probability calculation on the above-mentioned first-level feature data, the above-mentioned second-level feature data, and the above-mentioned third-level feature data based on a preset probability formula, thereby obtaining the probability of occurrence of the above-mentioned acute events. Specifically, the specific calculation of the above-mentioned probability formula can be shown in the following formula (2): Formula (2) Where P represents the probability of the aforementioned acute event occurring, and z is the data obtained by weighted calculation based on the aforementioned primary feature data, secondary feature data, and tertiary feature data; this application does not impose further limitations on this. Sleep_sore represents sleep efficiency. w n This represents the weight coefficient of the nth item. These weight coefficients are obtained in advance by the system based on the actual situation, and this application will not impose further restrictions or details on them.
[0041] S204. Based on the AERS value and occurrence probability of the acute event, a graded early warning is issued.
[0042] This application does not limit the specific implementation of the above-mentioned tiered early warning system. For example, this application may have a pre-set rule base, and this application may automatically trigger the corresponding tiered early warning system based on the above-mentioned AERS value and the probability of occurrence of acute events by querying the rule base. Several possible implementation methods are described below as examples, but they do not constitute a limitation.
[0043] In one implementation, when the AERS value is less than or equal to a preset first AERS threshold and the occurrence probability is less than or equal to a preset first probability threshold, this application can determine that the acute event is at a first risk level, such as a low risk level. Furthermore, this application can provide a first-level risk warning for the acute event. Specifically, for example, this application can push corresponding risk warning information to the user via a user's mobile application or SMS, such as prompting that today's activity level is low and suggesting appropriate walking, sending timely medication notifications, or mild warnings such as monitoring a recent weight gain trend and paying attention to dietary intake. The preset first AERS threshold and the preset first probability threshold are corresponding thresholds pre-defined by the system based on actual conditions. They can be empirical values customized based on user experience, or statistical values calculated based on a series of experimental data, for example, the preset first AERS threshold is 30, and the preset first probability threshold is 0.3, etc.
[0044] In another embodiment, when the AERS value is greater than the preset first AERS threshold and less than the preset second AERS threshold, and the probability of occurrence is greater than the preset first probability threshold and less than the preset second probability threshold, this application can determine that the acute event is at a second risk level, such as a medium risk level. Furthermore, this application can provide a second-level risk warning for the acute event, where the second level is higher than the first level. Specifically, this application can notify community doctors and family members to strengthen care, supervise medication administration, and conduct daily monitoring through a nursing management platform, telephone, or SMS. The preset second AERS threshold and the preset second probability threshold are corresponding thresholds pre-defined by the system based on actual conditions. They can be empirical values customized based on user experience or statistical values calculated from a series of experimental data. Typically, the preset second AERS threshold is greater than the preset first AERS threshold, and the preset second probability threshold is greater than the preset first probability threshold; for example, the preset second AERS threshold is 60, and the preset second probability threshold is 0.7, etc. This application does not impose further limitations on this.
[0045] In another embodiment, when the AERS value is greater than or equal to the preset second AERS threshold and the occurrence probability is greater than or equal to the preset second probability threshold, this application can determine that the acute event is at a third risk level, such as a high-risk level. Furthermore, a third-level risk warning can be issued for the acute event; specifically, for example, this application can directly contact doctors for emergency intervention and treatment through hospital internal alarm systems, instant messaging tools, or telephones. Simultaneously, some abnormal indicators, risk probabilities, and automatically generated electronic medical records of the user can be pushed to doctors to assist them in making rapid diagnostic decisions, etc., which this application will not limit or elaborate on further.
[0046] As can be seen, this application can analyze potential acute events of users by analyzing continuous and subtle time-series data trends, thus solving the problem of lag. By replacing fixed threshold judgments with a physiological baseline model, the judgment criteria vary from person to person and from time to time, significantly improving prediction accuracy. Through the extraction and fusion of multi-level features, various factors of user health status are comprehensively considered, providing a more comprehensive assessment basis for acute event early warning, thereby providing more targeted early warning assistance.
[0047] In specific implementation, this application can acquire multi-source fusion data, which is used to characterize multi-source data representing potential acute events of users; based on a preset physiological baseline model, multi-level feature extraction is performed on the multi-source fusion data to obtain corresponding multi-level feature data. The physiological baseline model is obtained in advance through unsupervised learning based on historical multi-source disease data and multi-level disease features; based on the multi-level feature data, the AERS value and probability of occurrence of acute events are calculated to obtain the AERS value and probability of occurrence of the acute events; and a graded early warning is performed based on the AERS value and probability of occurrence of the acute events. In this way, multi-level feature extraction and tiered early warning of acute events can be performed on the user's multi-source fusion data based on the physiological baseline model, thereby improving the accuracy, efficiency, and reliability of the early warning. It also solves the technical problems of lag and low accuracy in early warning of acute events in the prior art.
