[0021] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.
[0022] As Figure 1 shown, the embodiment of the present application provides a data comparison and analysis method based on retest results, which is executed by a computer or a server and the like electronic device, and specifically includes: S1, obtaining the retest result of any first detection platform for the target project, the target project being the project with abnormal initial test result, and the first detection platform being different from the second detection platform generating the abnormal initial test result.
[0023] In a medical laboratory, multiple detection platforms of the same model are equipped for detecting the same item, one of which is a standard detection platform with excellent performance and always in good maintenance state. These detection platforms are used for medical detection, i.e. obtaining initial test results, and then auditors will periodically review these initial test results, and if a certain initial test result does not conform to the patient's clinical symptoms or lacks correlation with other indicators, it will be marked as an abnormal initial test result. Once an abnormal initial test result occurs, a detection platform (first detection platform) different from the detection platform (second detection platform) that produced the abnormal initial test result will be selected to quickly retest the same item sample. The item involved here is commonly used in medical laboratories, such as blood sample testing. The above process occurs in real time, and as long as there is an abnormal initial test result, the device of the present application will immediately respond to obtain the retest result of another detection platform for the abnormal item sample in real time, ensuring the efficiency and timeliness of the detection process.
[0024] S2, calculating a difference value based on the abnormal initial test result and the retest result.
[0025] wherein, is the difference value of the i th sample, is the retest result of the i th sample, is the abnormal initial test result of the i th sample.
[0026] The calculation of the difference value is the difference calculation of the results of two different detection platforms, which can be a standard detection platform and a non-standard detection platform, or two non-standard detection platforms.
[0027] S3, calculating difference distribution data based on the accumulated multiple difference values, the difference distribution data including a difference distribution range and a first confidence interval.
[0028] The difference value of each item sample with an abnormality is continuously obtained, and when a certain number of difference values are collected, the difference distribution range and the first confidence interval are calculated based on these difference values, and the difference distribution range and the confidence interval are updated and calculated once for each retest result obtained subsequently.
[0029] S4, analyzing the consistency of the retest result and the abnormal initial test result based on the difference distribution data.
[0030] The retest result obtained each time is compared with the updated difference distribution data to determine the consistency of the retest result and the abnormal initial test result of the corresponding two detection platforms.
[0031] The embodiment only needs to replace the test platform to retest the items of the abnormal preliminary test results, and based on the real-time analysis of the retest results, whether the test results are consistent is quickly and timely found. The retest results of the items of the preliminary test results are retested by the first detection platform different from the first detection platform that produces the abnormal preliminary test results, and then the difference values are calculated based on the abnormal preliminary test results and the retest results, respectively, so that the difference between the test results of the two detection platforms is clearly and accurately obtained. Then, the difference distribution data is calculated based on the continuously accumulated difference values, and the data is continuously updated. Finally, the consistency of the retest results and the abnormal preliminary test results is analyzed based on the difference distribution data. This method fully excavates the data value of the retest sample in the abnormal result review, which is originally used, and deeply analyzes and reuses the data which is originally only used for single detection result verification, so that these data break through the limitation of single function. The process is simple, only needs to retest the abnormal preliminary test results, and compare the consistency of the results of the two devices, without manual comparison, so that the deviation of the detection platform can be quickly and timely found, the accuracy of the detection results is improved, and the treatment risk in the subsequent detection is avoided In one embodiment, the difference distribution data is calculated based on the accumulated plurality of difference values in step S3, comprising: S31, calculating the mean and standard deviation of the plurality of difference values.
[0032] Each time a difference value is updated, the mean and standard deviation of all difference values are calculated.
[0033] S32, calculating the upper limit and lower limit of the 95% difference distribution range based on the mean and standard deviation, respectively, to obtain the difference distribution range.
[0034] Exemplarily, the difference distribution range can be calculated by the following method: , , wherein, represents the lower limit of the difference distribution range, represents the upper limit of the difference distribution range, represents the mean of all difference values, represents the standard deviation of all difference values.
[0035] S33, calculating the upper limit and lower limit of the 95% confidence interval based on the mean, standard deviation and number of difference values, respectively, to obtain the first confidence interval.
[0036] Exemplarily, the first confidence interval can be calculated by the following method: , , wherein, represents the lower limit of the 95% confidence interval, represents the upper limit of the 95% confidence interval, represents the number of first retest results. This embodiment reflects the trend of the difference between the retest results and the abnormal initial test results of the two detection platforms in real time by dynamically calculating the mean and standard deviation of all difference values. Then, based on the mean and standard deviation, the upper and lower limits of the 95% difference distribution range are calculated to determine the approximate range of the difference. Finally, the upper and lower limits of the 95% confidence interval are calculated based on the mean and standard deviation. Compared with the traditional subjective judgment, this statistical evaluation method has stronger objectivity and reliability. It can effectively reduce human errors in management and provide a solid and scientific basis for subsequent analysis of the consistency of the retest results and the abnormal initial test results of the two detection platforms based on difference distribution data, making the entire difference analysis process more accurate.
[0037] In addition, the first confidence interval needs to be judged, specifically: whether the first confidence interval contains 0.
[0038] When the first confidence interval contains 0, that is, when ≤0≤ , it indicates that there is no significant difference between the retest results and the abnormal initial test results at the current confidence level, and then the step S4 can be executed to analyze the consistency of the retest results and the abnormal initial test results again.
[0039] When the first confidence interval does not contain 0, that is, when 0 < , it means that the confidence interval is completely on the right side of 0, indicating that the retest results are generally larger than the abnormal initial test results, that is, there is a "positive bias"; when < <0, it indicates that the confidence interval is completely on the left side of 0, indicating that the retest results are generally smaller than the abnormal initial test results, that is, there is a "negative bias".
[0040] When the first confidence interval does not contain 0, the above also needs to be compared with the preset value to determine whether the deviation of the retest results and the abnormal initial test results is within an acceptable range (such as ±5). If the first confidence interval completely exceeds this acceptable range (i.e., the lower limit is less than -5 and the upper limit is greater than 5), it indicates that the difference between the retest results and the abnormal initial test results is too large and exceeds the acceptable degree. In this case, it can be considered that the difference reflected by the first confidence interval is not reliable, and then the step S4 does not need to be executed.
[0041] This embodiment can timely identify the reliability of the first confidence interval by first judging the first confidence interval, avoid unnecessary subsequent analysis, improve efficiency, evaluate the consistency from multiple dimensions, reduce misjudgment and omission, and enhance the reliability and credibility of the analysis results.
[0042] In one embodiment, analyzing the consistency of the retest result and the abnormal initial test result based on the difference distribution data in step S4 includes: S41, respectively calculating the difference data between the retest results of each first detection platform and the abnormal initial test results, where the difference data includes a difference value or a relative difference value.
[0043] When comparing the retest results with the differential distribution data, the first retest data needs to be processed, that is, the retest results of the first detection platform are linked to the abnormal initial test results of the second detection platform. For example, the retest result is 4 and the abnormal initial test result is 5. Then the calculated difference is 5-4=1, which means that the retest result of a first detection platform is 1 lower than the abnormal initial test result of the second detection platform based on the abnormal initial test result of the second detection platform. The calculated relative difference is (5-4) / 5=0.2, which means that the retest result of a first detection platform is 0.2 lower than the abnormal initial test result of the second detection platform based on the abnormal initial test result of the second detection platform.
[0044] S42, determine whether each difference data belongs to the difference distribution range and the first confidence interval; if the difference data belongs to the difference distribution range and the first confidence interval, execute step S43; if the difference data does not belong to the difference distribution range or the first confidence interval, execute step S44.
[0045] S43, determining that the retest result is consistent with the abnormal initial test result; S44, determining that the retest result is inconsistent with the abnormal initial test result.
[0046] Compare the retest result of a first detection platform represented by the difference or relative difference with the difference distribution range and the first confidence interval. If the result is within both the difference distribution range and the first confidence interval, it means that the gap between the retest result of the corresponding first detection platform and the abnormal initial test result of the second detection platform is within a reasonable range, and it can be determined that the detections of the two detection platforms are consistent and normal. If it is not within the difference distribution range or the first confidence interval, it means that the gap between the retest result of the corresponding first detection platform and the abnormal initial test result of the second detection platform is beyond a reasonable range, and it can be determined that the detections of the two detection platforms are inconsistent and abnormal.
[0047] In addition, when it is determined that the two detection platforms are inconsistent, a warning can be issued to the corresponding two detection platforms, and relevant personnel can quickly carry out in-depth investigation on the measured platform according to the warning information, such as checking whether the equipment is normally running, whether there is a loophole in the detection process, whether the operator is operating normally, and the like. Through timely discovery and solution of problems, a series of erroneous decisions and adverse consequences that can be caused by inaccurate detection results can be avoided, and the detection performance of the measured platform can be further optimized, and the accuracy and stability of detection can be improved.
[0048] The embodiment associates the retest results of each detection platform with the abnormal preliminary measurement results, calculates the difference or relative difference as difference data, and then takes the abnormal preliminary measurement results as a standard to clearly show the specific gap between the first detection platform and the second detection platform. Then, the difference data is compared with the difference distribution range and the first confidence interval to determine whether it is within a reasonable range. Finally, whether the two detection platforms are consistent is determined according to the comparison result. This way, the data of the two detection platforms is analyzed for consistency, the data originally used only for single detection result verification is deeply analyzed and reused, the data breaks through the limitation of single function, the application efficiency of the data is maximized, the detection inaccurate situation is found in time, a reliable basis for ensuring detection quality is provided, and the reliability and credibility of the overall detection are improved.
[0049] As shown in FIG. 6, the difference distribution data calculated in step S3 can also be visually displayed. Figure 2
[0050] The horizontal coordinate is the average of the retest result of each first detection platform and the abnormal preliminary measurement result of the second detection platform, and the vertical coordinate is the difference or relative difference calculated in step S41. The yellow data points are the difference or relative difference between the retest result of each first detection platform and the abnormal preliminary measurement result of the second detection platform. The two yellow straight lines respectively represent the upper limit of the 95% difference distribution range and the lower limit of the 95% difference distribution range. The green dotted line represents the upper limit of the 95% confidence interval, the blue dotted line represents the lower limit of the 95% confidence interval, and the red dotted line represents the average of the difference value.
[0051] The embodiment can intuitively reflect the detection difference change trend of the same item between different platforms through real-time dynamic visual display, and provide real-time information support for laboratory managers.
[0052] As shown in FIG. 6, the difference distribution data calculated in step S3 can also be visually displayed. Figure 1 As shown in FIG. 6, the difference distribution data calculated in step S3 can also be visually displayed. S5, in response to the number of difference distribution data being greater than or equal to the preset number, constructing a linear regression model based on the retest result of each first detection platform and the abnormal preliminary test result of the second detection platform, the linear regression model including a regression straight line and a second confidence interval of the regression straight line.
[0053] When the difference distribution data obtained by analyzing the same target item exceeds a certain number (such as greater than or equal to 10), a linear regression model of each first detection platform and the second detection platform can be constructed, and the linear regression model can be updated each time a retest result is added, so that consistency comparison between platforms can be quickly performed, and a basis for potential system bias correction is provided.
[0054] S6, judging whether the retest result falls within the second confidence interval of the regression straight line; if the retest result does not fall within the confidence interval of the regression straight line, executing step S7, and if the retest result falls within the confidence interval of the regression straight line, executing step S8.
[0055] S7, determining that the retest result is inconsistent with the abnormal preliminary test result; S8, determining that the retest result is consistent with the abnormal preliminary test result.
[0056] The retest result obtained each time is compared with the second confidence interval of the corresponding regression straight line. If the retest result does not fall within the second confidence interval of the regression straight line, it indicates that the retest result of the first detection platform deviates from the reasonable range expected based on the regression model, and at this time, it is determined that the corresponding first detection platform and the second detection platform are inconsistent in detection, which helps to timely find the detection platform that may have detection bias. If the retest result falls within the second confidence interval of the regression straight line, it indicates that the detection result of the first detection platform is within a reasonable fluctuation range, and it is determined that the corresponding first detection platform and the second detection platform are consistent in detection.
[0057] The embodiment constructs a linear regression model including a regression straight line and its second confidence interval based on the retest result of each first detection platform and the abnormal preliminary test result of the second detection platform when the number of difference distribution data is greater than or equal to the preset number, and the model can be updated in time with the increase of the retest result, so that consistency comparison between platforms can be quickly performed. Then, it is judged whether the retest result falls within the second confidence interval of the regression straight line. If it does not fall within, it is determined that the corresponding first detection platform and the second detection platform are inconsistent in detection, and if it falls within, it is determined that the detection is consistent, which provides a basis for potential bias correction, can timely find the consistency of the test results of each first detection platform and the second detection platform, timely find abnormal data and detection platforms, and provides a reliable basis for ensuring detection quality, which helps to improve the reliability and credibility of the overall detection.
[0058] Further, when the first detection platform and the second detection platform are determined to be inconsistent, an alarm can be sent to the corresponding detection platform, and relevant personnel can quickly conduct in-depth investigation on the two detection platforms according to the alarm information, such as checking whether the equipment is normally running, whether there is a loophole in the detection process, whether the operator is operating normally, and the like. By discovering and solving the problems in time, a series of wrong decisions and adverse consequences caused by inaccurate detection results can be avoided, and the detection performance of the detection platform can be further optimized, and the accuracy and stability of the detection can be improved.
[0059] Further, the step S5 of constructing the linear regression model based on the retest results of each first detection platform and the abnormal preliminary test results of the second detection platform comprises: S51, calculating the regression coefficient and the intercept based on the retest results of each first detection platform and the abnormal preliminary test results of the second detection platform by using the least square method.
[0060] S52, generating a regression straight line based on the regression coefficient and the intercept.
[0061] Exemplarily, the regression straight line can be calculated in the following manner: , y represents the retest result of the first detection platform, x represents the abnormal preliminary test result of the second detection platform, represents the regression coefficient, represents the intercept.
[0062] S53, calculating the residual standard deviation based on the first retest result of each measured platform and the standard retest result of the standard platform.
[0063] S54, calculating the second confidence interval of the regression straight line based on the residual standard deviation.
[0064] According to the regression straight line, the retest result of the corresponding first detection platform can be predicted according to the abnormal preliminary test result of the second detection platform, but the predicted result may deviate from the actual first detection platform retest result, and because the predicted value of the second detection platform retest result based on the regression straight line may have a fluctuation interval, the residual standard deviation of the retest result and the abnormal preliminary test result is calculated, and then the second confidence interval of the regression straight line is calculated according to the residual standard deviation, so as to determine whether the actual retest result is within a reasonable fluctuation range. If the retest result falls within the second confidence interval, it means that the difference between the first retest result and the predicted result is within an acceptable range; if the retest result falls outside the second confidence interval, the difference between the retest result and the predicted result is too large. By calculating the second confidence interval, the detection deviation of the two detection platforms can be found in time, the accuracy and reliability of the detection result can be enhanced, and the stability and effectiveness of the entire detection system can be ensured.
[0065] For example, Figure 3As shown, the linear regression model constructed in step S5 can also be visually displayed.
[0066] The horizontal coordinate is the predicted retest result of the first detection platform, the vertical coordinate is the abnormal preliminary test result of the second detection platform, the yellow data points are the retest results of each first detection platform, the red straight line is the regression straight line, and the gray area is the second confidence interval of the regression straight line.
[0067] The embodiment displays the regression result in a graphical manner. By updating the model in real time, the manager can intuitively understand the consistency of the detection results between the first detection platform and the second detection platform, and provide a scientific basis for the quantitative analysis and correction of the system bias between the platforms.
[0068] As shown, Figure 4 The embodiment of the application also provides a data comparison and analysis device based on retest results, which specifically comprises: The acquisition module 101 is configured to acquire retest results of any first detection platform for target items, the target items being items with abnormal preliminary test results, and the first detection platform being different from the second detection platform that generates the abnormal preliminary test results; The first calculation module 102 is configured to calculate a difference value based on the abnormal preliminary test result and the retest result; The second calculation module 103 is configured to calculate difference distribution data based on the accumulated plurality of difference values, the difference distribution data including a difference distribution range and a first confidence interval; The analysis module 104 is configured to analyze the consistency of the retest result and the abnormal preliminary test result based on the difference distribution data.
[0069] In the embodiment, the specific processing of the acquisition module 101, the first calculation module 102, the second calculation module 103, and the analysis module 104 in the data comparison and analysis device based on retest results and the technical effects brought by the specific processing can be respectively referred to the related descriptions of steps 101-104 in the corresponding embodiments, which will not be repeated here.

[0070] The embodiment provided in the embodiment of the method exists as a device embodiment corresponding to the above method embodiment. The device for data comparison and analysis based on retest results provided in this embodiment only needs to replace the retest of the abnormal primary test result project, and performs real-time analysis based on the retest result to quickly and timely find out whether the test result is consistent. The retest result of the project of the primary test result anomaly is obtained through a first detection platform different from the first detection platform that produces the abnormal primary test result. Then, the difference value is calculated based on the abnormal primary test result and the retest result, respectively, and the difference between the test results of the two detection platforms is clearly and accurately obtained. Then, the difference distribution data is calculated based on the continuously accumulated difference value, and the data is continuously updated. Finally, the consistency of the retest result and the abnormal primary test result is analyzed based on the difference distribution data. This method fully excavates the data value of the retest sample in the abnormal result review, which is originally used for the purpose of the original use, and deeply analyzes and reuses the data that is originally only used for single detection result verification, so that these data break through the limitation of single function. The process is simple, only the retest of the abnormal primary test result is needed, and the consistency of the results of the two devices is compared, without manual comparison. The deviation of the detection platform can be quickly and timely found out, the accuracy of the detection result is improved, and the treatment risk that may occur in subsequent detection is avoided.
[0071] As shown in Figure 5 Further, the device for data comparison and analysis based on retest results provided in the embodiment of the application further comprises: The construction module 105 is configured to, in response to the number of difference distribution data being greater than or equal to a preset number, construct a linear regression model based on the retest result of each first detection platform and the abnormal primary test result of the second detection platform, wherein the linear regression model comprises a regression straight line and a second confidence interval of the regression straight line. The judgment module 106 is configured to judge whether the retest result falls within the second confidence interval of the regression straight line. If the retest result does not fall within the confidence interval of the regression straight line, it is determined that the retest result is inconsistent with the abnormal primary test result. If the retest result falls within the confidence interval of the regression straight line, it is determined that the retest result is consistent with the abnormal primary test result.
[0072] Further, the device for data comparison and analysis based on retest results provided in the embodiment of the application further comprises: The display module 107 is configured to visually display the difference distribution data and / or the linear regression model.
