[0002] As laboratory workload continues to increase, laboratory management, especially the use and inventory management of reagents, becomes increasingly complex.

[0003] At present, traditional reagent usage monitoring methods usually use preset fixed volume, reminder frequency and duration to remind staff to record the usage of reagents. When staff are busy with other inspection work, the fixed reminder parameters may be too frequent and cause interference; when the work is easier, the reminders may be insufficient and fail to remind staff to pay attention to recording in time; this inflexible reminder method cannot effectively adapt to changes in laboratory workload, resulting in reduced effectiveness of abnormal prompts. Summary of the invention

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present invention.

[0019] Embodiment 1, as Figure 1 As shown, the embodiment of the present invention provides a method for monitoring and processing reagent usage data in a laboratory of a clinical laboratory, which specifically includes the following steps: S100: After suspicious reagent usage occurs in the laboratory of the clinical laboratory, record behavior monitoring is performed. When no record behavior is detected within the preset time window, the latest inventory of the target reagent and the test data sequence of the target reagent used for testing within the most recent preset time range are retrieved.

[0020] Furthermore, step S100 of the present invention further includes: S110: After detecting the use of reagents in the laboratory of the laboratory department, record behavior monitoring is performed within a preset time window; S120: If recording behavior is detected, the process ends; if no recording behavior is detected, the latest inventory of the target reagent corresponding to the suspicious reagent use behavior is retrieved, and a sequence of test data for the test using the target reagent within the most recent preset time range is obtained, wherein each piece of test data includes the test time and the test result.

[0021] Specifically, after detecting the use of reagents in the laboratory of the laboratory, that is, when there are staff members in the laboratory using reagents, the use of reagents is monitored in real time. For example, when the staff opens the reagent cabinet and takes the reagents, the occurrence of this behavior is recorded; then, a preset time window is set (such as 5 minutes, which can be set according to the actual scenario), and within this time range, whether the staff has completed the recording behavior is monitored. Recording behavior refers to the recording information of reagent use input by the staff through electronic devices (such as computers, touch screens, etc.), including detailed information such as the name, quantity, and time of use of the reagents. If the recording behavior is detected within the preset time window, that is, if the staff has recorded it in time, the recording behavior will be confirmed and the monitoring will end.

[0022] If no recording behavior is detected within the preset time window, that is, the staff does not enter the use information within the specified time, it is considered to be a potential abnormal behavior, that is, suspicious reagent use behavior; at this time, the latest inventory of the target reagent is retrieved to view the current remaining amount of the reagent. On the other hand, a test data sequence of the target reagent used for testing within the recent preset time range (such as 24 hours, which can be set according to the frequency of use of the target reagent) is obtained, where each test data includes the test time and the test result. The test data sequence can help verify the specific circumstances of the reagent use. For example, if a certain reagent is frequently used recently and is not recorded, it may be found that there are problems of misoperation or management omissions.

[0023] S200: According to the inspection data sequence, inspection error analysis, inspection frequency and record anomaly analysis are performed to obtain the inspection error rate, inspection frequency and record anomaly rate. In combination with the procurement time cycle and the latest inventory, inspection shortage rate analysis is performed to obtain the inspection shortage rate.

[0024] Furthermore, step S200 of the present invention further includes: S210: In the inspection data sequence, extract the number of inaccurate inspection results to obtain the number of inaccurate inspections; S220: Calculate the ratio of the number of inaccurate inspections to the number of all inspection data in the inspection data array to obtain the inspection error rate; S230: Calculate the inspection frequency based on the number of all inspection data in the inspection data sequence and the time length of the preset time range; S240: Collect the number of times that the recording behavior is not monitored within the preset time window after the reagent usage behavior occurs within the most recent preset time range, obtain the number of abnormal recording behaviors, calculate the ratio to the number of all monitoring data, and obtain the recording abnormality rate.

[0025] Specifically, first, in the test data sequence, all inaccurate test results (for example, errors, outliers, etc.) are found, and the number of these inaccurate results is counted. These inaccurate test results reflect the problems that may exist in the use of reagents, such as reagent quality problems, operating errors or incomplete records, and the number of inaccurate tests is obtained. Then, the ratio of the number of inaccurate tests to the number of all test data in the test data array is calculated, and the ratio is set as the test error rate, wherein the test error rate reflects the frequency of inaccurate results in laboratory tests. If the test error rate is high, it means that there are more errors or anomalies in the use of reagents, which may affect the accuracy of the use of reagents and their impact on experimental results. If the use of reagents is not recorded in a timely manner, subsequent test data may not be correctly traced, resulting in the accuracy of experimental data being affected. For example, if the staff does not record the use of reagents on a certain occasion, and there is a problem with the reagents used that time, the subsequent test data may not be associated with the accurate use of the reagents, further affecting the traceability of the results; among them, the greater the test error rate, the greater the impact of unrecorded reagent use, that is, the higher the calculated test error rate, the greater the possibility of inaccurate results in the test. At this time, if there is a situation where the use of reagents is not recorded, it will be more difficult to trace the correct use when tracing the test results, thereby increasing the impact of the error.

[0026] On the other hand, the ratio of the number of all test data in the test data sequence to the time length of the preset time range is set as the test frequency, wherein the test frequency reflects the use frequency of the reagent, that is, the number of times the reagent is used for testing per unit time. If the test frequency of a certain reagent is high, it means that its use demand is large, and management needs to be strengthened to ensure sufficient inventory and avoid abnormal use. In addition, the number of times the use of the reagent is not recorded within the preset time window (such as 5 minutes) after the use of the reagent occurs within the recent preset time range (for example, the past day or week) is collected, and is set as the number of abnormal record behaviors; the ratio of the number of abnormal record behaviors to the number of all monitoring data is further calculated to obtain the record abnormality rate, which reflects the integrity of the reagent use record, that is, the probability that the staff forgets to record. For example, in the past 24 hours, a certain reagent has been used 100 times, of which 15 times the reagent was taken and the recording behavior was not monitored within 5 minutes, then these 15 times belong to the number of abnormal record behaviors, and the record abnormality rate is 15 / 100, which is equal to 15%, indicating that 15% of the reagent use is not recorded in time, which will affect inventory management and traceability of test data.

[0027] Furthermore, step S200 of the present invention further includes: S250: Calculate and obtain the theoretical shortage time according to the latest inventory quantity and inspection frequency; S260: Use the record abnormality rate to perform correction calculation on the theoretical shortage time to obtain the predicted shortage time.

[0028] Specifically, the latest inventory refers to the current inventory of reagents in the laboratory, that is, how much reagents can continue to be used for testing, usually expressed in units of reagents (such as bottles, milliliters, grams, etc.); the test frequency refers to the number of times or frequency that a certain reagent is used within a certain period of time, which can help us determine the consumption rate of the reagent; then the ratio of the latest inventory to the test frequency is set as the theoretical shortage time. By calculating the theoretical shortage time, the laboratory can predict whether the remaining inventory is sufficient to support the next work, provide a basis for purchasing decisions, and ensure that the laboratory can replenish reagents in time to avoid affecting the experimental process due to inventory shortages.

[0029] In laboratory reagent management, the record abnormality rate may lead to inaccurate inventory records. When the staff fails to record the use of reagents in time, the inventory data in the system may be more than the actual inventory. This difference may affect the actual inventory situation, resulting in an incorrect prediction of the reagent shortage time. In order to correct this problem, the theoretical shortage time can be corrected by introducing the record abnormality rate, and the predicted shortage time can be calculated. The predicted shortage time will more accurately reflect the actual inventory situation and provide a more reliable shortage warning. Then, the theoretical shortage time / 1+record abnormality rate is set as the predicted shortage time, where 1+record abnormality rate reflects the impact of record abnormality on inventory. If the record abnormality rate is high and the actual inventory is less than the recorded inventory, then the predicted shortage time will be shorter than the theoretical shortage time, reflecting the insufficient inventory in advance. For example, assuming that the theoretical shortage time is 5 days and the record abnormality rate is 15%, the predicted shortage time is 5 / (1+0.15), which is approximately equal to 4.35 days.

[0030] The predicted shortage time takes into account the impact of the record abnormality rate. Through the correction calculation, it more accurately reflects the actual inventory shortage time. Even if the inventory records show that there is enough inventory, when the actual inventory is insufficient, the predicted shortage time will show the risk of inventory shortage in advance, avoiding missing the opportunity to purchase or replenish due to record omissions. By introducing the record abnormality rate to correct the theoretical shortage time, the laboratory can still respond promptly when faced with inaccurate inventory data, avoiding the impact of negligence or system errors on laboratory work.

[0031] S270: Obtain the procurement time period, perform inspection shortage rate analysis based on the predicted shortage time, and obtain the inspection shortage rate.

[0032] Further, step S270 of the present invention further includes: S271: Obtain the procurement time cycle and the time point of the last reagent procurement, and calculate the remaining procurement time based on the current time; S272: Calculate the shortage time based on the predicted shortage time and the remaining procurement time, and calculate the ratio to the remaining procurement time to obtain the inspection shortage rate.

[0033] Specifically, obtain the procurement time cycle and the time point of the last reagent procurement. The procurement time cycle refers to the time interval from the last procurement to the next procurement; the last procurement time point refers to the time when the laboratory last made a procurement; then subtract the last procurement time point from the procurement time cycle, and take the difference between the two as the remaining procurement time. For example, assuming the procurement time cycle is 20 days and the last procurement time was 14 days ago, the remaining procurement time is 20 minus 14, which equals 6 days.

[0034] Next, subtract the predicted shortage time from the remaining procurement time, take the difference between the two as the shortage time, and take the ratio of the difference between the two to the remaining procurement time as the inspection shortage rate. For example, assuming that the remaining procurement time is 6 days and the predicted shortage time is 4.35 days, the inspection shortage rate is (6-4.35) / 6, which is equal to 0.275, or 27.5%. The inspection shortage rate reflects the difference between the predicted shortage time and the remaining procurement time, and thus shows the impact of the shortage on subsequent inspections. The higher the inspection shortage rate, the greater the risk of shortages in subsequent inspections and the more serious the impact of the shortage.

[0035] S300: Performing a procurement impact analysis based on the inspection frequency and the record abnormality rate to obtain a procurement impact rate.

[0036] Furthermore, step S300 of the present invention further includes: S310: Obtain the average inspection frequency in the historical period; S320: Calculate the ratio of the inspection frequency to the average inspection frequency to obtain the inspection speed impact rate; S330: Calculate the record impact rate based on the record abnormality rate, and calculate the procurement impact rate in combination with the inspection speed impact rate.

[0037] Specifically, first, obtain the average inspection frequency in the historical time. The inspection frequency refers to the number of inspections performed per unit time. In order to evaluate the normal use of laboratory reagents, it is necessary to calculate an average inspection frequency through historical data. The average inspection frequency is the ratio of the total number of inspections in the historical time to the length of the historical time. If 70 inspections were performed in the past 7 days, the average inspection frequency is 10 times per day. Then, the ratio of the inspection frequency to the average inspection frequency is used as the inspection speed impact rate. The inspection speed impact rate is used to measure the degree of change of the current inspection frequency relative to the historical average inspection frequency. It helps to determine whether the laboratory inspection speed has changed, thereby affecting the procurement rhythm. For example, assuming that the current inspection frequency is 12 times / day and the historical average inspection frequency is 10 times / day, the inspection speed impact rate is 1.2, indicating that the current inspection frequency is 20% higher than the historical average frequency.

[0038] Then, obtain the average record abnormality rate in the historical time, and set the ratio of the record abnormality rate to the average record abnormality rate as the record impact rate. For example, assuming that the current record abnormality rate is 18% and the average record abnormality rate is 12%, the record impact rate is 0.18 / 0.12, which is equal to 1.5, indicating that the current record abnormality rate is 50% higher than the historical average. Then multiply the test speed impact rate and the record impact rate, and set the product of the two as the procurement impact rate. For example, assuming that the test speed impact rate is 1.2 and the record impact rate is 1.5, the procurement impact rate is 1.5×1.2, which is equal to 1.8. The procurement impact rate comprehensively considers the changes in record abnormalities and test speed, which can help laboratories predict future procurement needs. If the procurement impact rate is high, the laboratory needs to purchase more reagents in advance.

[0039] S400: Calculate the inspection impact parameter based on the inspection error rate and the inspection shortage rate, calculate the monitoring impact parameter based on the procurement impact rate, generate prompt information based on the monitoring impact parameter as the monitoring processing result and provide a prompt.

[0040] Furthermore, step S400 of the present invention further includes: S410: According to the inspection error rate and the inspection shortage rate, weighted calculation is performed to obtain the inspection influence parameters; S420: According to the inspection influence parameters and the procurement influence rate, the monitoring influence parameters are calculated to obtain the monitoring influence parameters; S430: The monitoring influence parameters are input into the prompt classifier and classified to generate prompt information, wherein the prompt classifier includes a mapping relationship between a sample monitoring influence parameter interval set and a sample prompt level set; S440: The prompt information is used as the monitoring processing result and a prompt is given.

[0041] Specifically, weights are configured for the test error rate and the test shortage rate, and the weights represent the relative importance of each factor on the test. The weights can be adjusted according to the actual situation (for example, when the error rate has a greater impact on the test, a greater weight is given to the error rate). For example, the test error rate weight is set to 0.6, and the test shortage rate weight is set to 0.4; then, according to the weight configuration result, the test error rate and the test shortage rate are weighted to obtain the test impact parameter. For example, assuming that the test error rate is 15% and the test shortage rate is 27.5%, the test impact parameter is 0.15×0.6+0.275×0.4, which is equal to 0.2. The test impact parameter comprehensively considers the two important factors of the test error rate and the test shortage rate. Through weighted method, a comprehensive test impact value can be calculated according to the degree of influence of different factors on the test results.

[0042] The monitoring impact parameter combines the impact of inspection activities and the impact of procurement activities to help determine the impact of procurement decisions on laboratory inspection activities. It combines the inspection impact parameter and the procurement impact rate to quantify the potential impact of procurement decisions on reagent use management. The weight coefficients of the inspection impact parameter and the procurement impact rate are set separately. The weight coefficient represents the relative importance of each factor on the monitoring impact, which can be adjusted according to the actual needs and management experience of the laboratory. For example, the inspection impact parameter is 0.7 and the procurement impact rate is 0.3; the inspection impact parameter and the procurement impact rate are further weighted according to the weight coefficient to obtain the monitoring impact parameter.

[0043] First, define a sample monitoring influence parameter interval set, which represents different intervals of monitoring influence parameters, including low influence intervals, medium influence intervals, high influence intervals, etc.; then, define a sample prompt level set, which represents the prompt level that should be taken according to different monitoring influence parameter intervals, for example, low influence, medium influence, high influence, etc. Then, according to the mapping relationship between the sample monitoring influence parameter interval and the sample prompt level, based on the decision tree principle, the sample monitoring influence parameter interval is used as a child node, the corresponding sample prompt level is used as the leaf node of the child node, and the sample monitoring influence parameter interval set and the sample prompt level set are used as construction data to construct a prompt classifier. Further, the monitoring influence parameter is input into the prompt classifier for matching, and the prompt information is generated by classification; finally, the prompt information is used as the monitoring processing result and a prompt is given, including sound prompts, visual prompts, vibration prompts, etc. For example, a high-volume warning sound is played to ensure that the staff can notice it in time; a prompt box or a flashing visual logo pops up on the computer screen to remind the staff to record the use of reagents in time; if the staff is using a mobile device or wearing a smart device, it can also be reminded by vibration. Among them, the prompt classifier mapping table is shown in Table 1: Table 1: Prompt classifier mapping table

[0044] Through this table and mapping relationship, the laboratory can dynamically adjust the intensity and method of prompt information based on the monitoring impact parameters calculated in real time, ensuring that staff will not ignore important records or purchasing decisions when they are busy.

[0045] The embodiment of the present invention provides a method for monitoring and processing reagent usage data in a laboratory of a clinical laboratory, which has at least the following technical effects: After suspicious reagent use behavior occurs in the laboratory of the laboratory department, record behavior monitoring is performed. When no record behavior is detected within the preset time window, the latest inventory of the target reagent and the inspection data sequence of the target reagent used for inspection within the latest preset time range are retrieved; then, according to the inspection data sequence, inspection error analysis, inspection frequency and record abnormality analysis are performed to obtain the inspection error rate, inspection frequency and record abnormality rate, and the inspection shortage rate is analyzed in combination with the procurement time cycle and the latest inventory to obtain the inspection shortage rate; further, according to the inspection frequency and record abnormality rate, procurement impact analysis is performed to obtain the procurement impact rate; finally, the inspection impact parameters are calculated according to the inspection error rate and the inspection shortage rate, and the monitoring impact parameters are calculated in combination with the procurement impact rate, and prompt information is generated according to the monitoring impact parameters as the monitoring processing result and prompts are given. In other words, by analyzing the usage status according to information such as reagent usage data, inspection error, reagent inventory status, and dynamically adjusting the volume, duration and frequency of the prompt information according to the current reagent usage status, the scientificity, flexibility and accuracy of the prompt parameter setting can be improved, thereby effectively avoiding staff forgetting to record due to being busy, reducing the probability of underreporting and misreporting, and improving the quality of management and control of reagent use.
