It will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and processes have not been described in detail so as not to obscure the description of the invention with unnecessary detail. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
In a first embodiment, as shown in fig. 1, the embodiment of the invention provides a method for monitoring and processing reagent usage data in a laboratory of a clinical laboratory, which specifically comprises the following steps:
And S100, after suspicious reagent use behaviors appear in a laboratory of a clinical laboratory, monitoring recording behaviors, and when the recording behaviors are not monitored in a preset time window, calling the latest stock quantity of the target reagent and adopting the target reagent to carry out a test data sequence in the latest preset time range.
Further, the step S100 of the present invention further includes:
And S110, after the reagent usage behavior in the laboratory of the clinical laboratory is monitored, monitoring the recording behavior in a preset time window, and S120, if the recording behavior is monitored, ending, and if the recording behavior is not monitored, calling the latest stock quantity of the target reagent corresponding to the suspicious reagent usage behavior, and acquiring a test data sequence for testing by adopting the target reagent in the latest preset time range, wherein each test data comprises test time and test result.
Specifically, after the reagent usage behavior in the laboratory of the clinical laboratory is monitored, that is, when a worker uses the reagent in the laboratory of the clinical laboratory, the reagent usage behavior is monitored in real time, for example, when the worker opens the reagent cabinet and takes the reagent, the occurrence of the reagent usage behavior is recorded, then, a preset time window (for example, 5 minutes, which can be set according to the actual scene) is set, and whether the worker finishes recording the behavior is monitored in the time range. The recording behavior refers to recording information taken by a worker through electronic equipment (such as a computer, a touch screen and the like) and comprises detailed information such as reagent names, quantity, taking time and the like, and if the recording behavior is monitored within a preset time window, namely if the worker records in time, the recording behavior is confirmed and the monitoring is finished.
If the recorded behavior is not monitored within the preset time window, namely the staff does not input the access information within the preset time, the recorded behavior is considered to be a potential abnormal behavior, namely suspicious reagent use behavior, and at the moment, the latest stock quantity of the target reagent is called to check the current residual quantity of the reagent. On the other hand, a test data sequence for testing by using the target reagent within a latest preset time range (for example, within 24 hours, which can be set according to the use frequency of the target reagent) is obtained, wherein each test data comprises a test time and a test result, and the test data sequence can help to verify the specific condition of reagent use, for example, if a certain reagent is frequently used in the recent period and is not recorded, a problem of misoperation or management omission may be found.
And S200, performing inspection error analysis, inspection frequency and recording anomaly analysis according to the inspection data sequence to obtain an inspection error rate, an inspection frequency and recording anomaly rate, and performing inspection shortage rate analysis by combining a purchasing time period and the latest stock quantity to obtain an inspection shortage rate.
Further, step S200 of the present invention further includes:
The method comprises the steps of S210, extracting inaccurate quantity of test results in a test data sequence to obtain inaccurate test times, S220, calculating the ratio of the inaccurate test times to the quantity of all test data in a test data array to obtain a test error rate, S230, calculating to obtain test frequency according to the quantity of all test data in the test data sequence and the time length of a preset time range, S240, collecting the times that recording behaviors are not monitored in the preset time window after reagent use behaviors occur in the latest preset time range to obtain abnormal recording behavior quantity, and calculating the ratio of the abnormal recording behavior quantity to the quantity of all monitored data to obtain a recording abnormal rate.
Specifically, first, all inaccurate test results (for example, errors, abnormal values, etc.) are found out in the test data sequence, and the number of the inaccurate results is counted, wherein the inaccurate test results reflect possible problems in the use process of the reagent, such as reagent quality problems, misoperation or incomplete record, etc., so as to obtain the number of the inaccurate tests. And then, calculating the ratio of the number of inaccurate tests to the number of all test data in the test data array, and setting the ratio as a test error rate, wherein the test error rate reflects the frequency of inaccurate results in laboratory tests, and if the test error rate is higher, more errors or anomalies exist in the using process of the reagent, which possibly affect the using accuracy of the reagent and the influence of the reagent on the test results. If the usage of the reagent is not recorded in time, the subsequent test data may not be traced correctly, which results in that the accuracy of the test data is affected, for example, if the staff does not record the reagent taken for a certain time and the reagent used for this time has a problem, the subsequent test data may not be related to the accurate reagent usage condition and further affect tracing of the result, wherein the larger the test error rate is, the larger the influence of the reagent taking is when the reagent is not recorded, i.e. the higher the calculated test error rate is, the greater the possibility of inaccurate result in the test is, and if the condition that the reagent is not recorded exists, the tracing of the test result is more difficult to trace the correct usage condition, thereby increasing the influence of errors.
On the other hand, the ratio of the total amount of the test data in the test data sequence to the time length of the preset time range is set as a test frequency, wherein the test frequency reflects the use frequency of the reagent, namely the number of times the reagent is used for testing in unit time, and if the test frequency of a certain reagent is higher, the use requirement is larger, the reinforced management is needed, the sufficient inventory is ensured and the use abnormality is avoided. In addition, the number of times that the usage condition is not recorded in a preset time window (such as 5 minutes) after the usage of the reagent is generated in the latest preset time range (such as the past one day or one week) is collected and is set as the abnormal recording behavior number, the ratio of the abnormal recording behavior number to the total monitoring data number is further calculated to obtain the recording abnormality rate, the recording abnormality rate reflects the completeness of the reagent usage record, namely the probability that a worker forgets to record, for example, a certain reagent is used 100 times in the past 24 hours, wherein after 15 times of reagent is taken, the 15 times of reagent is not monitored in 5 minutes, the recording abnormality rate is 15/100 equal to 15%, and the 15% of reagent usage is represented not to be recorded in time, so that the stock management and the retrospective data can be influenced.
Further, step S200 of the present invention further includes:
S250, calculating and obtaining theoretical shortage time according to the latest stock quantity and the checking frequency, and S260, adopting the abnormal recording rate to correct and calculate the theoretical shortage time and obtaining predicted shortage time.
Specifically, the latest stock amount refers to the stock amount of the reagent in the laboratory at present, that is, how much reagent can be used for further inspection, usually expressed in units of the number of reagents (e.g., bottles, milliliters, grams, etc.), the inspection frequency refers to the number or frequency of times a certain reagent is used in a certain period of time, which can help to judge the consumption rate of the reagent, and then the ratio of the latest stock amount to the inspection frequency is set as a theoretical shortage time. Through calculation of theoretical shortage time, a laboratory can predict whether the rest stock is enough to support the next work, provides a basis for purchasing decision, ensures that the laboratory can timely supplement reagents, and avoids influencing the experimental process due to stock shortage.
In laboratory reagent management, recording anomaly rates may lead to inaccurate inventory records. When the staff does not record the use condition of the reagent in time, the inventory data in the system may be more than the actual inventory, the difference may influence the actual inventory condition, so that the erroneous pre-judgment of the reagent shortage time is caused, in order to correct the problem, the theoretical shortage time can be corrected by introducing the recording abnormality rate, the predicted shortage time is calculated, the predicted shortage time can more accurately reflect the actual inventory condition, and more reliable shortage pre-warning is provided. Next, the theoretical shortage time/1+ recording abnormality rate is set as a predicted shortage time, wherein the 1+ recording abnormality rate reflects the influence of recording abnormality on the stock, and if the recording abnormality rate is high, the actual stock is smaller than the recording stock, the predicted shortage time is shorter than the theoretical shortage time, and the shortage of stock is reflected in advance, for example, assuming that the theoretical shortage time is 5 days and the recording abnormality rate is 15%, the predicted shortage time is 5/(1+0.15) approximately equal to 4.35 days.
The predicted shortage time considers the influence of the abnormal rate of the record, and the real shortage time of the stock is reflected more accurately through correction calculation, even if the stock record is displayed sufficiently, when the real stock is insufficient, the predicted shortage time can display the risk of stock shortage in advance, and the opportunity of purchasing or supplementing is avoided being missed because of record omission. By introducing the recording anomaly rate to correct the theoretical shortage time, the laboratory can still respond timely when the inventory data is inaccurate, and the laboratory work is prevented from being influenced by negligence or systematic errors.
S270, acquiring a purchasing time period, and carrying out inspection shortage rate analysis according to the predicted shortage time to acquire the inspection shortage rate.
Further, step S270 of the present invention further includes:
s271, acquiring a purchasing time period and a time point of last reagent purchasing, calculating and acquiring residual purchasing time according to the current time, S272, calculating and acquiring the shortage time according to the predicted shortage time and the residual purchasing time, and calculating the ratio of the shortage time to the residual purchasing time to acquire the checking shortage rate.
Specifically, the time period of purchasing and the time point of last reagent purchasing are obtained, the time period of purchasing refers to the time interval from last purchasing to next purchasing, the time point of last purchasing refers to the time of last purchasing in a laboratory, then the time period of purchasing is adopted to subtract the time point of last purchasing, the difference value of the time period of last purchasing and the time point of last purchasing is taken as the residual purchasing time, for example, the time period of purchasing is assumed to be 20 days, and the time period of last purchasing is assumed to be 14 days before the time of last purchasing, and the time of residual purchasing is 20 minus 14 days to be equal to 6 days.
Then, the predicted shortage time is subtracted from the remaining purchase time, the difference between them is taken as the shortage time, and the ratio of the difference between them and the remaining purchase time is taken as the inspection shortage rate, for example, assuming that the remaining purchase time is 6 days and the predicted shortage time is 4.35 days, the inspection shortage rate is (6-4.35)/6 is equal to 0.275, namely 27.5%, the inspection shortage rate reflects the difference between the predicted shortage time and the remaining purchase time, thereby showing the degree of influence of shortage on the subsequent inspection, and the higher the inspection shortage rate, the greater the risk of occurrence of shortage in the subsequent inspection, the more serious the degree of influence of shortage.
And S300, carrying out purchasing influence analysis according to the checking frequency and the recording anomaly rate to obtain the purchasing influence rate.
Further, step S300 of the present invention further includes:
S310, obtaining average checking frequency in historical time, S320, calculating the ratio of the checking frequency to the average checking frequency to obtain a checking speed influence rate, S330, calculating to obtain a recording influence rate according to the recording abnormal rate, and calculating to obtain a purchasing influence rate by combining the checking speed influence rate.
Specifically, first, an average test frequency in a history time is obtained, the test frequency being the number of tests performed per unit time, and in order to evaluate the routine condition of laboratory reagent use, it is necessary to calculate an average test frequency from history data, the average test frequency being the ratio of the total test number in the history time to the length of the history time, and if 70 tests were performed in the past 7 days, the average test frequency was 10 times per day. Then, the ratio of the test frequency to the average test frequency is used as a test speed influence rate, and the test speed influence rate is used for measuring the change degree of the current test frequency relative to the historical average test frequency, so as to help judge whether the laboratory test speed is changed, and further influence the purchasing rhythm, for example, if the current test frequency is 12 times per day and the historical average test frequency is 10 times per day, the test speed influence rate is 1.2, and the current test frequency is higher than the historical average frequency by 20%.
Then, an average recording abnormality rate in the history time is obtained, and the ratio of the recording abnormality rate to the average recording abnormality rate is set as a recording influence rate, for example, assuming that the current recording abnormality rate is 18% and the average recording abnormality rate is 12%, the recording influence rate is 0.18/0.12 equal to 1.5, indicating that the current recording abnormality rate is 50% higher than the history average. Then multiplying the test speed influence rate by the record influence rate, setting the product of the test speed influence rate and the record influence rate as the purchase influence rate, for example, assuming that the test speed influence rate is 1.2 and the record influence rate is 1.5, the purchase influence rate is 1.5 x 1.2 and is equal to 1.8, comprehensively considering the record abnormality and the change of the test speed by the purchase influence rate, and helping a laboratory predict future purchase demands, and if the purchase influence rate is higher, the laboratory needs to purchase more reagents in advance.
S400, calculating to obtain a test influence parameter according to the test error rate and the test shortage rate, calculating to obtain a monitoring influence parameter by combining the purchase influence rate, generating prompt information according to the monitoring influence parameter, and prompting as a monitoring processing result.
Further, step S400 of the present invention further includes:
The method comprises the steps of S410, obtaining a test influence parameter through weighted calculation according to the test error rate and the test shortage rate, S420, obtaining a monitoring influence parameter through calculation according to the test influence parameter and the purchase influence rate, S430, inputting the monitoring influence parameter into a prompt classifier, classifying and generating prompt information, wherein the prompt classifier comprises a mapping relation between a sample monitoring influence parameter interval set and a sample prompt grade set, and S440, taking the prompt information as a monitoring processing result and prompting.
Specifically, the weight configuration is performed for the inspection error rate and the inspection shortage rate, the weight represents the relative importance of each factor on the inspection effect, the weight can be adjusted according to the actual situation (for example, when the error rate has a larger effect on the inspection, the error rate is given a larger weight), for example, the inspection error rate weight is set to be 0.6, the inspection shortage rate weight is set to be 0.4, then, according to the weight configuration result, the weighing calculation is performed for the inspection error rate and the inspection shortage rate to obtain the inspection effect parameter, for example, assuming that the inspection error rate is 15% and the inspection shortage rate is 27.5%, the inspection effect parameter is 0.15×0.6+0.275×0.4 to be equal to 0.2. The test influence parameters comprehensively consider two important factors of the test error rate and the test shortage rate, and a comprehensive test influence value can be calculated according to the influence degree of different factors on the test result in a weighting mode.
The monitoring of the influence parameters integrates the influence of the inspection activities and the influence of the purchasing activities, helps to judge the influence of the purchasing decisions on laboratory inspection activities, combines the inspection influence parameters and the purchasing influence rate, and can quantify the potential influence of the purchasing decisions on reagent use management. The method comprises the steps of respectively setting weight coefficients of a test influence parameter and a purchase influence rate, wherein the weight coefficients represent the relative importance of each factor on monitoring influence, and can be adjusted according to actual requirements and management experience of a laboratory, for example, the test influence parameter is 0.7, the purchase influence rate is 0.3, and further carrying out weighted calculation on the test influence parameter and the purchase influence rate according to the weight coefficients to obtain the monitoring influence parameter.
A set of sample monitoring influence parameter intervals is first defined, which sets represent different intervals of the monitoring influence parameter, including low influence intervals, medium influence intervals, high influence intervals, etc., and a set of sample prompt levels is then defined, which sets represent prompt levels to be taken according to the different monitoring influence parameter intervals, e.g. low influence, medium influence, high influence, etc. And then, based on a decision tree principle, taking the sample monitoring influence parameter interval as a child node, taking the corresponding sample prompting level as a leaf node of the child node, taking the sample monitoring influence parameter interval set and the sample prompting level set as construction data, and constructing a prompting classifier. The monitoring influence parameters are further input into a prompt classifier to be matched, prompt information is generated through classification, finally, the prompt information is used as a monitoring processing result and is prompted in modes of voice prompt, visual prompt, vibration prompt and the like, for example, high-volume warning sounds are played, so that workers can be timely notified, a prompt frame or a flashing visual mark is popped up on a computer screen, the workers are reminded of timely recording reagent use, and if the workers use mobile equipment or wear intelligent equipment, the workers can also be reminded through vibration. The hint classifier mapping table is shown in table 1:
TABLE 1 prompt classifier mapping table
Through the table and the mapping relation, the laboratory can dynamically adjust the strength and the mode of the prompt information according to the monitoring influence parameters calculated in real time, so that the staff can not ignore important record or purchase decisions when busy.
