Brief Description of the Drawings

[0022] [Figure 1] It is a diagram showing an apparatus for estimating the quantity of a drug according to an embodiment of the present invention. [Figure 2] It is a diagram showing a flow for estimating the quantity of a drug according to an embodiment of the present invention. [Figure 3] It is a diagram showing a medical institution function based on individual drug data and medical institution data for each feature amount according to an embodiment of the present invention.

Mode for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0024] FIG. 1 shows an apparatus according to an embodiment of the present invention. The apparatus 100 acquires, for example, individual drug data regarding drugs accumulated for each medical institution for some medical institutions within a certain region from a cloud electronic medical record system, and acquires medical institution data regarding medical institutions throughout the region from a wholesaler. Although various data may be acquired by communication via an IP network such as the Internet, it is only necessary that the apparatus 100 can acquire them by any other means. Among the medical institutions within a certain region, although only some medical institutions adopt a specific cloud electronic medical record system, by receiving medical institution data regarding medical institutions throughout the region from a wholesaler or the like and using this complementarily, it is possible to estimate the demand for drugs throughout the region. FIG. 1 illustrates an example in which individual drug data is acquired from a medical record system and medical institution data is acquired from a wholesaler, but the data providers are not limited to these.

[0025] The apparatus 100 includes a communication unit 101 such as a communication interface, a processing unit 102 such as a processor or a CPU, and a storage unit 103 including a storage device or a storage medium such as a memory or a hard disk, and can be configured by executing a program for performing each process or each operation in the processing unit 102. The apparatus 100 may include one or more devices, computers or servers. Also, the program may include one or more programs, and can be made into a non-transitory program product recorded on a computer-readable storage medium. The program is stored in a storage device or a storage medium such as a database 104 accessible via an IP network from the storage unit 103 or the apparatus 100, and instructions included in the program can be executed in at least one processor of the processing unit 102. The data described as being stored in the storage unit 103 below may be stored in a storage device or a storage medium such as the database 104, and vice versa.

[0026] Specifically, the device 100 first acquires individual drug data for some medical institutions within the region, which is accumulated for each medical institution (S201). An example of individual drug data is shown in Table 1 below. Although only six records are shown here, it is preferable to acquire a large number of individual drug data within the target area for quantity estimation.

[0027] [Table 1]

[0028] Individual drug data may include a medical institution identifier that identifies a medical institution, a drug identifier that identifies a drug, the quantity of the drug, and data that allows for the determination of the number of medical institutions for each feature. The medical institution identifier may be a symbol such as pharma_id or a medical institution name such as a pharmacy name. The drug identifier may also be a symbol that identifies the drug or a drug name. The quantity may be the order quantity, delivery quantity, or prescription quantity. Individual drug data may further include the period for which the quantity was recorded, such as year and month.

[0029] Features include, as will be described later, the medical department, the range of concentration rates, the range of transaction amounts, the range of patient numbers, and the range of prescription numbers. Medical departments include general internal medicine, respiratory medicine, otolaryngology, etc. The concentration rate is the percentage of the hospitals that issued the most prescriptions among all the hospitals that received prescriptions from the medical institution. Transaction amounts include order amounts, delivery amounts, etc. Medical departments are themselves features of the medical institution and are data that can determine those features, while the concentration rate and transaction amounts are data that can determine the range of concentration rates and the range of transaction amounts, respectively, which are features of the medical institution. The same applies to the range of patient numbers and the range of prescription numbers.

[0030] Next, the device 100 acquires data on medical institutions for the entire region (S202). The medical institution data may include the number of medical institutions for each feature in the medical institutions for the entire region, or data that allows for direct or approximate determination of these numbers. For example, in the example of medical institution data shown below, if the feature is medical department, the number of medical institutions for each medical department can be determined by counting the number of medical institutions for each medical department.

[0031] [Table 2]

[0032] Table 2 shows only partial records, but in practice, it is desirable to include records for all healthcare institutions in the target region. Furthermore, wholesalers do business with numerous healthcare institutions in each region, and it is desirable that the healthcare institution data provided by wholesalers include data for all healthcare institutions in each region, but it is also acceptable if it does not strictly include all of them, but rather represents data that approximates the data for all healthcare institutions in each region.

[0033] The medical institution data may include multiple medical institution identifiers that identify multiple medical institutions, and data that allows for the determination of the number of medical institutions for each feature in the multiple medical institutions included in the medical institution data. If the multiple medical institutions included in the medical institution data represent all medical institutions in the entire region, the number of medical institutions for each feature determined based on the medical institution data will strictly represent the number of medical institutions for each feature in the entire region. If not all medical institutions are included, it will approximately represent the number of medical institutions for each feature in the entire region. Since the medical institution data complements the individual drug data for each medical institution, the multiple medical institutions included in the medical institution data will include at least one medical institution that is not included in the multiple individual drug data obtained.

[0034] The medical institution data may further include drug identifiers that identify drugs. In this case, the number of medical institutions based on the medical institution data can be the number of medical institutions for each drug and each feature. Alternatively, if medical institution data is selectively acquired for drugs that are the subject of quantity estimation, the number of medical institutions based on the medical institution data will be the number of medical institutions for each feature of that drug, even if the medical institution data does not include drug identifiers.

[0035] Next, the device 100 corrects the individual quantities included in the individual drug data for each medical institution according to the characteristic quantities of that medical institution and calculates the corrected individual quantities (S203). An example using the medical department as a characteristic quantity is explained below.

[0036] First, let's assume that for 18 pharmacies in a certain region, individual drug data for the drug "Xofluza 20mg tablets" is obtained from a cloud-based electronic medical record system, and medical institution data for 119 pharmacies in the same region is obtained from a wholesaler. Then, the number of pharmacies for each medical specialty (pediatrics, respiratory medicine, general internal medicine, and otolaryngology) is calculated from the individual drug data and medical institution data, and the number of medical institutions based on the individual drug data is corrected by multiplying by 119 / 18, resulting in the diagram shown in Figure 3. In the example in Figure 3, according to the data from the medical record system, the proportion of pharmacies specializing in general internal medicine is the highest, while according to the data from the wholesaler, the proportion of pharmacies specializing in respiratory medicine is the highest. Thus, since the data from the medical record system is expected to be biased as it only covers a portion of the pharmacies in the region, a correction coefficient is determined to match or approach the feature distribution based on the data from the wholesaler, which covers a larger number of pharmacies, and these correction coefficients are used to correct the individual quantities included in the individual drug data for each pharmacy.

[0037] For example, in the example in Figure 3, according to the data from the medication history system, there are 6 pharmacies specializing in respiratory medicine, and multiplying this by 119 / 18 gives 39.7. According to the data from wholesalers, the number is 64. In this case, the quantities included in the individual drug data for pharmacies specializing in respiratory medicine can be corrected as follows. Individual quantity after correction = Individual quantity × (119 / 18) × (64 / 39.7) =Individual quantity×(64 / 6)

[0038] The device 100 then estimates the total quantity of the target drug in all medical institutions in the region based on the corrected individual quantities for each medical institution (S204). By using the corrected individual quantities for each medical institution, the total quantity for the region can be estimated by augmented estimation.

[0039] In the above explanation, the medical department was used as a feature. When using a range of concentration rates as a feature, the concentration rate from 0.0 to 1.0 can be divided into multiple ranges, and the range of concentration rates can be determined as a feature of a medical institution based on the concentration rate values ​​included in the individual drug data of each medical institution. The same applies when using ranges of transaction amounts, patient numbers, prescription numbers, etc., as features. Furthermore, the quantity of drugs may be estimated using multiple features and the final quantity may be estimated by averaging those quantities.

[0040] Furthermore, while the above explanation adjusts individual quantities for each medical institution, it is also possible to first sum the individual quantities for each medical institution, calculate the unadjusted quantities for each feature within the region, and then adjust these unadjusted quantities according to the features to estimate the quantity of drugs within that region.

[0041] Furthermore, in the embodiments described above, unless the word "only" is used, such as "based only," "depending only," "in the case of only," or "referencing only," it is assumed in this specification that additional information may also be considered. Also, as an example, the statement "if a, then b" does not necessarily mean "always b in the case of a" or "b immediately after a," unless explicitly stated otherwise. In addition, the statement "each a constituting A" does not necessarily mean that A is composed of multiple components, but includes the possibility that the component is singular.

[0042] Furthermore, it should be noted that the embodiments of the present invention described above are included in the disclosure herein, in any way that they are not inconsistent with each other.

[0043] Furthermore, for the sake of clarity, even if there are aspects of operation in some method, program, terminal, device, server, or system (hereinafter referred to as "method, etc.") that differ from the operation described herein, each aspect of the present invention is intended to cover the same operation as any of the operations described herein, and the existence of operation different from the operation described herein does not mean that such method, etc. is outside the scope of each aspect of the present invention.

[0044] Furthermore, the "start" and "end" shown in Figure 2 are merely examples, and do not necessarily mean that the method according to this embodiment will always start or end in the illustrated procedure. [Explanation of Symbols]
