Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of data processing and relates to a method and system for intelligent blood sugar monitoring in nephrology. Background Art
[0002] Blood glucose is an important indicator for assessing the normality of human glucose metabolism and is usually used to screen, diagnose and monitor a variety of abnormal glucose metabolism diseases such as diabetes and hypoglycemia. Blood glucose monitoring is of great significance in the work of nephrology. It can help doctors to timely discover and intervene in problems related to glucose metabolism and improve the treatment effect and quality of life of patients. In order to accurately understand the changes in patients' blood glucose levels, doctors usually use monitoring equipment such as blood glucose meters or external attached sensors to obtain patients' real-time blood glucose data, and judge whether there is abnormal blood glucose by the proportion of time when blood glucose is within the normal range. In the process of monitoring patients' blood glucose levels, doctors usually assess the risk of patients' illness based on the percentage of time when the patient's blood glucose reaches the standard. The percentage of time when the blood glucose reaches the standard is the percentage of time when the blood glucose value is in the normal range between the high and low thresholds. The higher the percentage, the lower the risk. However, the setting of normal blood glucose thresholds is often based on research data of large-scale populations and cannot be well applied to all patients. In addition, the fluctuation of blood glucose in patients is also very important for the assessment and diagnosis of the disease, and the percentage of time when the blood glucose reaches the standard cannot reflect this fluctuation. Therefore, although the method of using thresholds to judge whether blood glucose levels are normal is simple and easy, it has the defects of inaccuracy and incompleteness in practical application, which may lead to certain deviations in the analysis results and reduce the accuracy and real-time performance of monitoring. Summary of the invention
[0003] The purpose of the present invention is to solve the problem that the method of using the normal blood sugar threshold to judge whether the blood sugar level is normal in the prior art is simple and easy, but in actual application, there are defects of inaccuracy and incompleteness, which may cause certain deviations in the analysis results, reduce the accuracy and real-time performance of the monitoring, and provide a method and system for intelligent monitoring of blood sugar in nephrology. To achieve the above purpose, the present invention adopts the following technical scheme to achieve it: a method for intelligent monitoring of blood sugar in nephrology, including: collecting blood sugar data of patients that continuously change over a period of time; based on the local change characteristics of the collected blood sugar data, obtaining the corresponding abnormal blood sugar change factor; based on the change law of blood sugar data, obtaining the relative deviation of blood sugar data; based on the obtained abnormal blood sugar change factor and the relative deviation of blood sugar data, determining the attention of blood sugar data; based on the periodic performance and overall attention of blood sugar data, obtaining the final blood sugar level risk score; based on the size of the blood sugar level risk score, comparing the set blood sugar score threshold, evaluating whether the patient's blood sugar is abnormal; if so, issuing an early warning; if not, indicating that the patient is in good health.
[0004] A further improvement of the present invention is that: further, the patient's blood sugar data that changes continuously over a period of time is collected, specifically: a fixed collection frequency for the patient's blood sugar data is set based on a blood sugar meter; at the same time, the patient's daily meal time is recorded and the patient's collection cycle is set.
[0005] Furthermore, based on the local variation characteristics of the collected blood sugar data, the corresponding blood sugar variation abnormality factor is obtained, specifically: any blood sugar data is set as reference data, and a fixed-size neighborhood is set for the reference data. for: ,in, For reference data, Represents the first individual data; represents the first-order difference of blood glucose data, where ; and are two adjacent blood sugar change values, is a symbolic function; Indicates the degree of blood sugar change in the neighborhood of the reference data. The larger the value, the more drastic the blood sugar change around the reference data. Also bigger; Indicates the number of blood glucose data in the neighborhood; Represents the number of pairwise combinations of adjacent blood glucose data in the neighborhood; It indicates the frequency of blood sugar fluctuation in the neighborhood of the reference data. If the directions of two adjacent changes are consistent, 1 if the direction is inconsistent, -1; The smaller the value of, the higher the blood sugar fluctuation frequency in the reference data neighborhood, and the higher the corresponding blood sugar abnormality factor The bigger.
[0006] Furthermore, based on the variation pattern of blood sugar data, the relative deviation of blood sugar data is obtained, specifically: ,in, is the mean of all blood sugar data in the sample, is the maximum blood sugar data in the sample, is the minimum blood sugar data in the sample; is the difference between the reference data and the mean, It represents the maximum difference between all the data in the sample and the mean. It is the ratio of the mean deviation of the reference data to the maximum mean deviation. The larger the value is, the greater the relative deviation of the reference data is, and the higher the corresponding attention is.
[0007] Furthermore, the attention level of blood sugar data is determined as follows: ,in, is the time point of the reference data, The closest to the reference data Meal time points, Indicates the abnormal blood sugar change factor based on the reference data at meal time. is the abnormal blood sugar change factor of the reference data, The larger the value, the more attention the reference data receives. It represents the time interval between the two meals closest to the reference data. The smaller the interval, the higher the attention.
[0008] Further, the periodic performance based on blood sugar data is as follows: ,in, The intensity of the blood glucose curve cycle of the patient; Indicates the number of days from the time of recording. Blood sugar data, The total number of blood sugar data in one day; Indicates the number of the same time point every day in the past u days. individual data; Indicates the attention level of the j-th blood sugar data in the past k-th day; For the past u days Mean blood sugar data at time points, In the past days Mean value of attention to blood glucose data at a time point; Indicates that blood sugar data samples The similarity of data based on attention at a time point, The smaller the value of The smaller the difference in blood sugar data at each time point, the stronger the blood sugar curve cycle performance. The greater the blood sugar level risk score The larger the for The smaller the value, the closer the data attention is to each time point. The closer the blood sugar data at each time point are, the The greater the difference in blood glucose data at each time point, the greater the impact on the intensity of the blood glucose curve cycle performance.
[0009] Furthermore, based on the periodic performance and overall attention of blood sugar data, the final blood sugar level risk score is obtained, specifically: ,in, to create a risk score for the final blood sugar level; Indicates the first data, Indicates the total number of data in the sample; is the attention variance of all blood glucose data in the sample; Indicates the overall attention level of all blood sugar data in the sample. The larger the value is, the worse the stability of the blood sugar data in the blood sugar data sample is, the lower the blood sugar regulation speed is, and the corresponding blood sugar level risk score is The bigger.
[0010] Further, based on the size of the blood sugar level risk score, the set blood sugar score threshold is compared, specifically: setting the blood sugar score threshold and ;like , it means that the patient's blood sugar level is normal; , it reminds the patient that the blood sugar condition is poor and needs to be adjusted in time; if , it means that the patient's blood sugar condition is abnormal and needs to be treated by a doctor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] The present invention is further described in detail below in conjunction with the accompanying drawings: Figure 1 , the present invention discloses an intelligent blood glucose monitoring method for nephrology, including: S101, collecting blood glucose data of patients that continuously change over a period of time; setting a fixed collection frequency for the patient's blood glucose data based on a blood glucose meter; and recording the patient's daily meal time and setting the patient's collection cycle. Specifically, it can be: using a blood glucose meter or externally attached sensor and other monitoring equipment to obtain the continuous u-day blood glucose data of nephrology patients in real time, and the data collection frequency is once every 10 minutes. In addition, it is also necessary to record the patient's daily meal time, and then construct the corresponding blood glucose data sample and upload it to the cloud for real-time monitoring and analysis. Among them, the collection duration and collection frequency are both empirically set, and the value of u can be set to 15 days; it can be adjusted according to actual conditions in specific applications.
[0022] S102, based on the local change characteristics of the collected blood sugar data, the corresponding abnormal blood sugar change factor is obtained; due to individual differences between different patients, each person's normal blood sugar range has different standards, and the conventional method of blood sugar monitoring method for risk assessment based on the percentage of blood sugar reaching the standard time of the patient uses a fixed threshold suitable for most people, which is not suitable for all people, and is prone to deviations in the analysis results. Not only that, the patient's blood sugar fluctuation is also very important for the evaluation and diagnosis of blood sugar status, and the percentage of blood sugar reaching the standard time cannot reflect this fluctuation, resulting in poor final monitoring effect. Therefore, it is first necessary to calculate the abnormal blood sugar change factor of each data according to the fluctuation characteristics and change trend of blood sugar, and then use the abnormal factor and data deviation to obtain the attention of the data, and finally obtain the final blood sugar level risk score according to the periodic performance and overall attention of the blood sugar data.
[0023] The conventional method of evaluating blood sugar levels relies more on some special blood sugar data, that is, analyzing whether the patient's blood sugar level is normal by the size of the data exceeding the threshold and the duration of the data. However, the limitations of threshold judgment and the existence of individual differences lead to low accuracy of this method, and it is easy to ignore the blood sugar data that may be abnormal. In practice, there are also large differences in the fluctuation of blood sugar data between normal individuals and abnormal individuals. The blood sugar data of abnormal individuals has poor stability and a relatively large range of variation. Therefore, in order to better mine these data that may be abnormal, the corresponding blood sugar change abnormality factor can be calculated according to the local change characteristics of each data to reflect the fluctuation of the data and distinguish the degree of attention to different data.
[0024] According to the above logic, first calculate the corresponding abnormal blood sugar change factor for all blood sugar data in the sample. Take any blood sugar data as reference data, set a fixed-size neighborhood for the reference data, and the neighborhood contains 5 adjacent blood sugar data before and after. The abnormal blood sugar change factor of this data for: ,in, For reference data, Represents the first individual data; represents the first-order difference of blood glucose data, where ; and are two adjacent blood sugar change values, is a symbolic function; Indicates the degree of blood sugar change in the neighborhood of the reference data. The larger the value, the more drastic the blood sugar change around the reference data. Also bigger; Indicates the number of blood glucose data in the neighborhood; Represents the number of pairwise combinations of adjacent blood glucose data in the neighborhood. The value of is set to 10, which means that the neighborhood contains 5 adjacent blood glucose data before and after. The value of should be 9; It represents the frequency of blood sugar fluctuation in the neighborhood of the reference data. If the directions of two adjacent changes are consistent, then 1 if the direction is inconsistent, -1; The smaller the value of, the higher the blood sugar fluctuation frequency in the reference data neighborhood, and the higher the corresponding blood sugar abnormality factor The bigger.
[0025] At this point, the blood sugar abnormality factor of all data in the sample can be obtained through the above steps, and then the next step of calculation can be performed.
[0026] S103, based on the changing pattern of blood sugar data, obtain the relative deviation of blood sugar data; when monitoring the patient's blood sugar data, more attention should be paid to the data of some special time nodes, such as the peak value, valley value or blood sugar value exceeding the threshold of the blood sugar curve. These special data can better reflect the patient's blood sugar health level. For patients with nephrology who may have physical abnormalities, their blood sugar may rise or fall too much after a meal due to the deterioration of the reabsorption function of the kidneys. Therefore, the relative deviation of blood sugar data rather than a fixed threshold can be used to measure the attention of the data. In addition, the insulin secretion time and total amount of nephrology patients may be different from those of normal people, which makes their blood sugar regulation abnormal for a period of time after a meal. Therefore, the blood sugar data before and after meals also have a high analytical value.
[0027] Based on the changing pattern of blood sugar data, the relative deviation of blood sugar data is obtained, specifically: ,in, is the mean of all blood sugar data in the sample, is the maximum blood sugar data in the sample, is the minimum blood sugar data in the sample; is the difference between the reference data and the mean, It represents the maximum difference between all the data in the sample and the mean. It is the ratio of the mean deviation of the reference data to the maximum mean deviation. The larger the value is, the greater the relative deviation of the reference data is, and the higher the corresponding attention is.
[0028] S104, based on the acquired blood sugar change abnormality factor and the relative deviation of the blood sugar data, determine the attention level of the blood sugar data; the attention level of the blood sugar data is recorded as , we can get: ,in, is the time point of the reference data, The closest to the reference data Meal time points; Indicates the abnormal blood sugar change factor based on the reference data at meal time. is the abnormal blood sugar change factor of the reference data, The larger the value, the more attention the reference data receives. It represents the time interval between the two closest meals of the reference data. The smaller the interval, the higher the attention. So far, the attention of all data in the sample can be obtained through the above steps, and then the next step of calculation can be carried out.
[0029] S105, based on the periodic performance and overall attention of blood glucose data, the final blood glucose level risk score is obtained; since the blood glucose level of the human body is closely related to the daily rhythm, the change of blood glucose data has a strong daily periodicity, and the stronger the periodicity, the lower the possibility of risk. However, there are more or less differences in people's diet, exercise, and environment every day. The existence of these differences will weaken the periodic performance of blood glucose data, which may lead to deviations in the assessment of patient blood glucose risk. In order to solve the above problem, the previously obtained data attention can be used for weighting when calculating the patient's blood glucose cycle performance. Data with similar attention are likely to be blood glucose data under similar conditions. When calculating, a higher weight is given, and vice versa. In addition, the blood glucose level of a normal individual is usually relatively stable and flat during the day, and only changes greatly before and after meals, and the speed of blood glucose regulation is also faster; and the blood glucose level of an abnormal individual will not only undergo more unstable changes, but also slow down the blood glucose regulation speed due to the weakening of the body's absorption and metabolic functions. Therefore, abnormal individuals have more high-attention blood glucose data than normal individuals, and the overall attention is higher.
[0030] The cycle performance based on blood sugar data is as follows: ,in, The intensity of the blood glucose curve cycle of the patient; Indicates the number of days from the time of recording. Blood sugar data, is the total number of blood sugar data in one day; here the value of u is 15 days; Indicates the number of times at the same time every day in the past 15 days. individual data; Indicates the attention level of the j-th blood sugar data in the past k-th day; For the past 15 days Mean blood sugar data at time points, In the past 15 days Mean value of attention to blood glucose data at a time point; Indicates that blood sugar data samples The similarity of data based on attention at a time point, The smaller the value of The smaller the difference in blood sugar data at each time point, the stronger the blood sugar curve cycle performance. The greater the blood sugar level risk score The larger the for The smaller the value, the closer the data attention is to each time point. The closer the blood sugar data at each time point are, the The greater the difference in blood glucose data at each time point, the greater the impact on the intensity of the blood glucose curve cycle performance.
[0031] Based on the periodic performance and overall attention of blood sugar data, the final blood sugar level risk score is obtained, specifically: ,in, to create a risk score for the final blood sugar level; Indicates the first data, Indicates the total number of data in the sample; is the attention variance of all blood glucose data in the sample; Indicates the overall attention level of all blood sugar data in the sample. The larger the value is, the worse the stability of the blood sugar data in the blood sugar data sample is, the lower the blood sugar regulation speed is, and the corresponding blood sugar level risk score is The bigger.
[0032] At this point, the corresponding blood sugar level risk score can be obtained through the patient's blood sugar data for the past 15 days. This score can reflect the patient's blood sugar health status in the past 15 days. The higher the score, the worse the health status and the more likely there is a risk of disease.
[0033] S106, based on the size of the blood sugar level risk score, compare it with the set blood sugar score threshold to evaluate whether the patient's blood sugar is abnormal; if so, issue a warning; if not, it means that the patient is in good health.
[0034] Setting blood sugar score thresholds and ; is 0.6, is 0.8, if ,Right now , it means that the patient's blood sugar level is normal; ,Right now , it means that the patient's blood sugar condition is poor and needs to be adjusted in time; if ,Right now , it means that the patient's blood sugar condition is abnormal and needs to be treated by a doctor.
