Abstract
Description
Technology Field
[0001] The present invention relates to an electronic device, method, and computer program for determining the optimal aggregation size of a pooled test method for the diagnosis of infectious diseases. More specifically, the invention relates to an electronic device, method, and computer program for determining the optimal aggregation size of a pooled test method for the diagnosis of infectious diseases, which can induce an efficient pooled test method by determining the minimum pooled size as the optimal pooled size through a test count calculation function that calculates the total number of tests, which is the total number of diagnostic tests performed in the pooled test step and the individual test step included in the pooled test method, for each pooled size based on the prevalence rate of the infectious disease and the number of subjects in the pooled test method. Background Technology
[0003] Molecular diagnostics is a representative in vitro diagnostic method that detects the cause of a disease or the presence of infection by detecting nucleic acids (DNA, RNA, or their variants) from disease-causing bacteria, viruses, and other pathogens. The molecular diagnostic process consists of a pretreatment step to obtain pure nucleic acids, a gene amplification step using Polymerase Chain Reaction (PCR), and a diagnostic step involving analysis. Among these, the pretreatment step is the process of extracting nucleic acids containing target genes from biological samples to secure the target genes intended for gene amplification.
[0004] Such pretreatment processes consume a significant amount of time due to steps such as mixing samples with various reagents and handling residues. Furthermore, since these procedures are carried out in laboratories equipped with necessary equipment (such as centrifuges), samples collected from patients, including blood, must be transported to the laboratory. However, as infectious diseases like COVID-19 have recently shown a rapid rate of infection leading to a surge in patients, rapid diagnosis and follow-up measures are required above all else. In other words, rapid diagnosis at the scene is essential.
[0005] Meanwhile, the sample pretreatment process requires mixing samples with various reagents, necessitating specialized personnel with relevant expertise. However, in situations where the number of patients surges, there is a severe shortage of skilled professionals to handle the situation, which causes the molecular diagnostic process to take a long time. To address this issue, pooled testing methods have been introduced, in which multiple samples are combined into a single sample and individual retests are performed on the remaining samples if the result is positive. However, problems are arising, such as a decrease in testing speed, as the number of tests increases depending on the number of samples mixed. Prior art literature

[0043] FIG. 1 is a conceptual diagram of an electronic device and an external device for determining the optimal aggregation size of a pooled test method for diagnosing an infectious disease according to one embodiment of the present invention, FIG. 2 is a block diagram of an electronic device for determining the optimal aggregation size of a pooled test method for diagnosing an infectious disease according to one embodiment of the present invention, and FIG. 3 is a diagram for explaining a pooled test method to which an electronic device for determining the optimal aggregation size of a pooled test method for diagnosing an infectious disease according to one embodiment of the present invention is applied.
[0044] Referring to FIGS. 1 to 3, an electronic device (100) for determining the optimal aggregation size of a pooled test method for diagnosing an infectious disease according to one embodiment of the present invention can determine the optimal aggregation size to minimize the total number of tests performed when the prevalence rate and the number of test subjects are determined, through a test count calculation function that calculates the total number of tests, which is the total number of diagnostic tests performed in the pooled test step and the individual test step included in the pooled test method, according to the pooled size, based on the prevalence rate of the infectious disease and the number of test subjects in the pooled test method.
[0045] Here, the pooled testing method may be a diagnostic testing method for infectious diseases consisting of a sample collection step, a pooled testing step, and an individual testing step, as illustrated in FIG. 3.
[0046] Specifically, during the sample collection stage, samples can be collected from each of the multiple subjects who visited the testing center.
[0047] Subsequently, in the pooled testing stage, specimens collected from each of the multiple subjects are pooled and mixed in a pooled size to form a pooled group, and then a diagnostic test for an infectious disease can be performed on each of the multiple pooled groups.
[0048] Subsequently, in the individual testing stage, diagnostic tests are performed individually on each specimen collected in the pooled group in which the diagnostic test result in the pooled testing stage was diagnosed as positive, thereby identifying test subjects infected with an infectious disease.
[0049] An electronic device (100) for determining the optimal aggregation size of a pooled test method for diagnosing an infectious disease according to one embodiment of the present invention can optimally determine the aggregation size, which is the number of specimens collected from test subjects and aggregated into one aggregation group, in the pooled test step of the pooled test method described above.
[0050] To this end, an electronic device (100) for determining the optimal aggregate size of an aggregate test method for diagnosing an infectious disease according to one embodiment of the present invention may include a processor (140), a display unit (150), an input unit (120), a communication unit (110), and a memory (130).
[0051] The communication unit (110) can receive various information and data from an external device (200) that is necessary for the electronic device (100) determining the optimal aggregation size of the aggregate test method for diagnosing an infectious disease according to one embodiment of the present invention to determine the optimal aggregation size.
[0052] Specifically, the communication unit (110) can receive the prevalence rate of infectious diseases and the number of subjects subject to the pooled testing method from an external device (200).
[0053] Here, the external device (200) may be one or more of the servers of a local health center managing infectious diseases and a health authority.
[0054] The input unit (120) can receive various information and data necessary for the electronic device (100) for determining the optimal aggregation size of an aggregate test method for diagnosing an infectious disease according to one embodiment of the present invention to determine the optimal aggregation size.
[0055] Specifically, the input unit (120) can receive input from the user regarding the prevalence rate of infectious diseases and the number of subjects subject to the pooled testing method.
[0056] To this end, the input unit (120) may be equipped with one or more of a mouse device, a keyboard device, a tablet device, and a touch module.
[0057] Previously, the prevalence rate of infectious diseases and the number of subjects received by the communication unit (110) or the prevalence rate of infectious diseases and the number of subjects entered by the input unit (120) can be set in the test count calculation function by the processor (140).
[0058] A detailed explanation regarding this will be provided later.
[0059] Memory (130) can store a function to calculate the number of checks.
[0060] Here, the test count calculation function may be a function that calculates the total number of tests, which is the total number of diagnostic tests performed in the pooled test stage and the individual test stage included in the pooled test method, according to the pooling size based on the prevalence of the infectious disease and the number of subjects in the pooled test method.
[0061] In other words, the test count calculation function may be a function that calculates the total number of tests based on the aggregation size, given that the prevalence rate of the infectious disease and the number of subjects in the pooled test method are fixed.
[0062] Specifically, the function for calculating the number of tests can calculate the total number of tests by summing the first number of tests, which is the number of diagnostic tests performed in the aggregated test stage, and the second number of tests, which is the number of diagnostic tests performed in the individual test stage based on the results of the aggregated test stage.
[0063] At this time, the test count calculation function can calculate the first test count according to the aggregate size using the number of test subjects.
[0064] In addition, the test count calculation function can calculate the expected value of a test result diagnosed as positive when a diagnostic test is performed the first number of times at the pooled test stage using the prevalence rate and the first number of tests, and can calculate the second number of tests using the expected value and the pooling size.
[0065] Such a function for calculating the number of checks can be expressed by the following mathematical formula 1.
[0067] <Mathematical Formula 1>
[0068]
[0069] Here, E(R) is the total number of tests, N1 is the number of the first test, N2 is the number of the second test, and N is the number of test subjects, and is the expected value, g is the pool size, and p' is the probability that the test result of a diagnostic test for any one pool group will be diagnosed as positive according to the prevalence.
[0071] That is, the processor (140) inputs the prevalence rate of the infectious disease and the number of subjects received by the communication unit (110) or the prevalence rate of the infectious disease and the number of subjects input by the input unit (120) into a test count calculation function and sets the total number of tests, which is the output value of the test count calculation function that is calculated differently as the aggregation size is changed, into an optimal aggregation size such that the minimum total number of tests is calculated as the output value.
[0072] Figure 4 is a graph showing the optimal aggregation size by prevalence rate determined by an electronic device for determining the optimal aggregation size of an aggregation test method for diagnosing infectious diseases according to one embodiment of the present invention.
[0073] Referring to FIG. 4, the processor (140) can predetermine the optimal aggregation size by using a test count calculation function set by setting the number of test subjects to “100,000” and changing the prevalence rate from “0%” to “100%”.
[0074] Meanwhile, the processor (140) compares the total number of inspections according to the determined optimal aggregation size with the number of subjects, and if the total number of inspections according to the determined optimal aggregation size exceeds the number of subjects, it may decide not to perform the aggregation inspection method.
[0075] Meanwhile, the memory (130) can store a function to calculate the number of inspections according to another embodiment.
[0076] Here, the function for calculating the number of tests according to another embodiment may be a function that calculates the total number of tests, which is the total number of diagnostic tests performed in the pooled test stage and the individual test stage included in the pooled test method, by pooling size based on the positivity rate of the infectious disease and the number of subjects in the pooled test method.
[0077] That is, the test count calculation function according to another embodiment may be a function that calculates the total number of tests by aggregate size based on the positivity rate and the number of subjects, rather than the prevalence rate, compared to the test count calculation function according to one embodiment.
[0078] At this time, the processor (140) according to another embodiment can determine the optimal aggregate size by using a test count calculation function according to another embodiment, which is a function that calculates the total number of tests based on the positive rate and the number of test subjects in each aggregate size when the prevalence rate is not obtained due to the initial transmission stage of the infectious disease.
[0079] Specifically, in the case where the prevalence rate is not obtained and only the positivity rate is obtained due to the initial transmission stage of the infectious disease, the processor (140) according to another embodiment can set the positivity rate and the number of test subjects in the test count calculation function according to another embodiment.
[0080] Subsequently, the processor (140) according to another embodiment can determine the optimal aggregation size such that the test count calculation function according to another embodiment, in which the positive rate and the number of test subjects are set, calculates the minimum total number of tests.
[0081] At this time, the processor (140) according to another embodiment compares the regional positive rate, which is the positive rate of infectious disease in the region where the aggregate testing method is performed, with the national positive rate, which is the positive rate of infectious disease in the country, and based on the comparison result, can determine the positive rate set in the test count calculation function according to another embodiment as either the regional positive rate or the national positive rate.
[0082] Specifically, the processor (140) according to another embodiment may set the regional positive rate to the positive rate set in the test count calculation function according to another embodiment if the regional positive rate is smaller than the national positive rate.
[0083] Conversely, if the regional positive rate is greater than the national positive rate, the processor (140) according to another embodiment may set the national positive rate to the positive rate set in the test count calculation function according to another embodiment.
[0084] Additionally, when the processor (140) according to another embodiment determines the positive rate set in the test count calculation function according to another embodiment as the regional positive rate, it determines whether the change value of the regional positive rate exceeds a reference change value, and based on the result of the determination, the positive rate (regional positive rate) set in the test count calculation function according to another embodiment may be determined as either the first regional positive rate, which is the regional positive rate during the first past period from the time of execution when the aggregated test method is performed, or the second regional positive rate, which is the regional positive rate during the second past period from the time of execution.
[0085] Specifically, the processor (140) according to another embodiment may set the first regional positive rate to the positive rate set in the test count calculation function according to another embodiment when the change value of the regional positive rate exceeds the reference change value.
[0086] Conversely, the processor (140) according to another embodiment may set the second regional positive rate to the positive rate set in the test count calculation function according to another embodiment if the change value of the regional positive rate is less than or equal to the reference change value.
[0087] Here, the first past period may be shorter than the second past period.
[0088] That is, if the change in the positive rate is large, the positive rate of a short past period can be set by inputting it into a test count calculation function according to another embodiment, and if the change in the positive rate is small, the positive rate of a long past period can be set by inputting it into a test count calculation function according to another embodiment.
[0089] FIG. 5 is a diagram showing a screen in which an electronic device for determining the optimal aggregate size of an aggregate test method for diagnosing an infectious disease according to one embodiment of the present invention outputs the optimal aggregate size.
[0090] Referring to FIG. 5, the processor (140) can control the display unit (150) so that the determined optimal aggregation size is displayed on the screen.
[0091] At this time, the processor (140) can control the display unit (150) so that the prevalence rate, the number of subjects, etc., along with the determined optimal aggregation size, are displayed on the screen.
[0092] Through this, inspectors at the testing center can perform the aggregate testing method by checking the optimal aggregate size displayed on the screen.
[0093] To this end, the display unit (150) may be equipped with a display module.
[0094] The processor (140) can perform the operation of each of the components described above and may include one or more cores (not shown) and a graphics processing unit (not shown) and / or a connection channel (e.g., a bus, etc.) for transmitting and receiving signals with other components.
[0095] The processor (140) may be configured to perform the operation of each of the components described above by executing one or more instructions stored in memory (130).
[0096] The memory (130) can store programs (one or more instructions) for processing and controlling the processor (140). The programs stored in the memory (130) can be divided into multiple modules according to their function.
[0097] The memory (130) can store data, information, and signals to perform the functions described above.
[0098] FIG. 6 is a flowchart of a method for determining the optimal aggregate size of an aggregate test method for diagnosing an infectious disease according to one embodiment of the present invention.
[0099] Referring to Fig. 6, in step S1, the processor obtains the prevalence of the infectious disease and the number of subjects subject to the pooled testing method.
[0100] Subsequently, in step S2, the processor sets the prevalence rate and the number of subjects in a test count calculation function that calculates the total number of tests—which is the total number of diagnostic tests performed in the pooled test stage and individual test stage included in the pooled test method—based on the prevalence rate of the infectious disease and the number of subjects in the pooled test method, according to the pooling size.
[0101] Finally, in step S3, the processor determines the optimal aggregation size such that the test count calculation function, with the prevalence rate and the number of test subjects set, calculates the minimum total number of tests.
