[0001] This invention relates to a dispensing support system for assisting in the mixing and management of drugs including liquid agents and the like.
Background Art
[0002] In the mixing operation of injection drugs and the dispensing operation performed in a small-scale pharmacy, the dispensing operation by manual labor is still the mainstream. Regarding the dispensing operation including such manual labor, some dispensing support systems have been proposed to reduce the burden on dispensers by automation or semi-automation (see, for example, Patent Documents 1, 2, etc.). In addition, in the mixing operation of anticancer drugs, which may particularly handle highly toxic drugs, the amount of drug used is often individually varied according to the patient's physique, etc., and a certain amount of residual liquid may occur during use. Conventionally, such residual liquid has been recommended for disposal, but in recent years, methods for reusing such residual liquid with sufficient consideration for safety have been explored due to the increase in medical costs and disposal costs. For example, in a fully automated mixing device, a method has been proposed to efficiently use the residual drug by retaining the residual liquid in the device (see, for example, Patent Document 3, etc.). However, the dispensing operation of drugs often inevitably includes manual labor as described above, and a dispensing support system that supports the management of residual drugs with consideration for safety has been demanded.

[Figure 15] This is an example of a display screen during an audit when leftover medication is used with a dispensing support system. [Modes for carrying out the invention]
[0008] A specific example of the dispensing support system of the present invention will be described with reference to Figure 1. In the following explanatory diagrams, for the sake of simplification, only those necessary or related to the explanation of the invention are shown.
[0009] As shown in Figure 1, the dispensing support system 10 comprises a programmable information processing device 13, a reader 11, an electronic scale 12, an operation input device 15, and a prescription information input device 16 connected to the information processing device 13 by signal cables, etc. as input devices for the information processing device 13, and a display device 14 connected to the information processing device 13 by signal cables, etc. as an output device for the information processing device 13. In this example, all of these are installed on the dispensing table 4 or another dispensing table 4', respectively. Here, we will illustrate a case where assistance is provided for dispensing medication, specifically in the process of drawing out or mixing the required amount of liquid medication (drug M) from a supply container 6 (described later) using a manual inhalation device 8 such as a syringe.
[0010] The information processing device 13 is an information processing unit that receives prescription information such as prescriptions from a higher-level system 200 such as an electronic medical record system, as shown in Figure 2. It is an information processing terminal equipped with programmable general-purpose hardware such as a personal computer, and programs and data installed on that hardware. A reader 11 is connected to the information processing device 13 as a reading means for reading recognition codes such as barcodes displayed on supply containers 6, such as the outer box of the drug M. Furthermore, a database 80 is provided either inside or outside the information processing device 13 as a drug master database that allows access to information about drugs, and is connected to the information processing device 13 in a manner that enables bidirectional communication. The dispensing support system 10 also includes an electronic scale 12 as a measuring means capable of measuring the weight of the supply container 6 containing the drug M during the dispensing process.
[0011] The information processing device 13 includes a display control means 40 that creates display data related to the dispensing work of the pharmacist, including the drug name, prescribed amount, prescribed amount, etc. of drug M, from the input prescription information; a remaining drug confirmation means 50 that registers drug M remaining in the supply container 6 as remaining drug; and an identification number issuing means 60 that issues a lot number, which is a unique identification number, for drug M for which remaining drug M has been registered. The remaining medication determination means 50 includes a remaining medication amount calculation means 54, an expiration date determination means 56, and a prescription specified amount confirmation means 57.
[0012] The operation input device 15 is a device for inputting desired information into the information processing device 13 by human operation, and in this embodiment, it is a foot pedal located below the dispensing counter 4. By using a foot pedal in this way, it can be operated with the foot even when the dispensing operator's hands are occupied at the dispensing counter 4. The operation input device 15 is not limited to this configuration, and may be an existing input device such as a mouse or keyboard operated by the fingers. Alternatively, an integrated configuration may be adopted in which the operation input device 15 and the display device 14 are combined into a touch panel system that allows for simultaneous display and input operations.
[0013] The dispensing table 4 is a work table on which a pharmacist performs the dispensing work of extracting liquid medication from a supply container 6 containing the drug M using a manual inhalation device 8. It can be a simple flat desk, a dispensing shelf with a work surface, a standalone piece of equipment, or equipment attached to other equipment, as long as the dispensing work can be performed with the dispensing support system 10 installed. It is often installed in hospitals but can be installed elsewhere, can be placed under atmospheric pressure, in positive or negative pressure environments, and can be placed inside or outside cleanrooms or clean benches.
[0014] A reader 11 and an electronic scale 12 are placed on the work surface of the dispensing counter 4, and a supply container 6 and a manual inhalation device 8 are also placed there during dispensing. Furthermore, a display device 14, which is an image projection device, is installed in a part of the dispensing counter 4 that is easily visible to the dispensing pharmacist, and an operation input device 15 is installed in a part of the dispensing counter 4 that is easily operated by the dispensing pharmacist. In this example, the information processing device 13 is also installed on the dispensing counter 4 for illustrative purposes. However, the information processing device 13 and prescription information input device 16, which are not directly perceived or operated by the pharmacist, may be installed in a different location from the dispensing counter 4, and may also be connected to the information processing device 13 via a network. Furthermore, multiple dispensing counters 4' with the same configuration as dispensing counter 4 may be provided.
[0015] As shown in Figure 3, the supply container 6 in this embodiment is a sealed container that contains a drug M, particularly a liquid drug, and typical examples include vials, bottles, ampoules, and bags. Liquid drugs are typically injectable drugs, but also include diluents used to dilute injectable drugs, tablets and powders that are liquefied before administration, solvents used for liquefaction, and intravenous solutions for drip infusions consisting of physiological saline. Note that when assisting in dispensing work that handles drugs other than liquid drugs, such as tablets or boxed drugs, the supply container 6 may not be sealed. The manual inhalation device 8 is a device that allows liquid medication to be extracted from the supply container 6 and inhaled into its internal space by manual operation. Typical examples include syringes with needles attached or syringes without needles. For handling medications other than liquids, measuring cups or similar devices may also be used.
[0016] The electronic scale 12 is a precision scale capable of accurately measuring the weight of the supply container 6 containing the drug M and the manual inhalation device 8 used to inhale the drug M, and transmits the measured weight, i.e., the weight value of the measurement result, to the information processing device 13 (see, for example, Patent Document 1).
[0017] The prescription information input device 16 consists of, for example, a wired LAN interface built into the information processing device 13 and / or a wireless communication device attached externally to the information processing device 13. It acquires the contents of prescription instructions, i.e., prescription data (prescription information from electronic prescription data) and dispensing instruction data (supported prescription information), from a higher-level system 200 such as the external prescription reception device or prescription order entry system described above, and provides them for data processing in the information processing device 13. Furthermore, since prescription information can also be entered into the information processing device 13 using the operation input device 15, the operation input device 15 can also be considered a type of prescription information input device. The prescription information input device 16, the operation input device 15, the display device 14, and the information processing device 13, which will be described in detail below, may be integrated with any other device, or they may all be separate devices.
[0018] In this embodiment, the identification number issuing means 60 includes a printer 61 as a printing means for printing the issued lot number. Printer 61 prints information such as lot number, drug name, dosage, ingredient amount, expiration date, preparation date and time, preparer, final auditor, order number, inpatient / outpatient status, patient number, patient name, etc., and also prints a display code 62 as a barcode so that the lot number can be read by reader 11. The printer 61 prints a sticker 63, which includes, for example, a lot number and a display code 62, in such a manner that it can be attached to the remaining medication M corresponding to the lot number from the outside of a sealing member 90 such as a zipper, as will be described later. In this embodiment, the printer 61 is located on the final auditing desk 5 in Figure 1, but it may also be located on the dispensing desks 4 and 4', or at any location where it can be connected to the information processing device 13.
[0019] The reader 11 is a barcode reader capable of reading, for example, a display code 62 linked to a lot number as shown in Figure 8 and described later, and a regular code 70, which is an identification code as shown in Figure 3, written on a supply container 6 such as the outer box of the drug. It is placed, for example, on the dispensing counter 4 or on the final audit counter 5. The reader 11 is connected to the information processing device 13, and when it reads the display code 62 or the regular code 70, it can transmit identification information of the corresponding drug M to the information processing device 13 according to the code.
[0020] In this embodiment, the display device 14 is a display means for visually displaying dispensing instruction information in a position easily visible in front of the dispenser when they are seated at the dispensing counter 4, and is shown as an image projection device such as a projector. The information processing device 13 transmits the display data created by the display control means 40 to the display device 14, and the display device 14 sequentially displays the display data according to the procedure, for example, according to the input of the preparer. By visually checking this displayed data while dispensing, the dispenser can safely dispense the medication while confirming the actual prescribed amount of drug M, precautions, and other dispensing instructions.
[0021] A method for managing leftover medication using such a dispensing support system 10 will be explained with reference to Figure 4. In this embodiment, the explanation will be divided into two cases: when newly prepared medication M is registered as leftover medication, and when medication M that has been registered as leftover medication is used. The instruction to register remaining medication for drug M is made in advance by turning on the "Remaining Medication Management" flag for drug M in the drug master data on the information processing device 13. The user, including the preparer and final auditor, can arbitrarily decide which drugs will be subject to remaining medication management. Furthermore, it is desirable that this type of medication management be carried out only for liquid medications.
[0022] First, whether or not medication management is performed, prescription data (prescription information from electronic prescription data) and dispensing instruction data (supported prescription information) are input from the upper-level system 200 to the information processing device 13 via the prescription information input device 16 (prescription information acquisition step S101).
[0023] These prescription data are simultaneously transmitted to various devices other than the dispensing support system 10, and the dispenser manually or automatically loads the prescribed medications, including drug M, as described in the prescription data, into the tray 100 (preparation step S102).
[0024] The higher-level system 200 manages trays 100 by numbers such as patient numbers and tray numbers, or by RP (so-called claims), and in the pre-preparation step, medications are prepared for each RP according to these numbers and the name and prescribed amount of the corresponding medication M. In this case, the higher-level system 200 may notify the dispenser of the medications to be prepared via the dispensing support system 10, or it may communicate prescription data to an external device such as a known automated dispensing device so that the medications are dispensed into the tray 100. Alternatively, these means may be combined.
[0025] Once these preparatory steps are completed and the necessary medications are secured in tray 100, a pre-audit is performed to confirm whether or not all the necessary medications are present in tray 100 (pre-audit step S103). In the preceding audit step or an earlier stage, injectable drugs such as anticancer drugs are prepared in RP units and administration units according to the dispensing instruction data and placed in tray 100 together with dispensing instruction sheets on which the dispensing instructions have been printed.
[0026] After the preliminary audit step, the preparer brings tray 100 into a clean environment such as the aforementioned cleanroom or sterile room according to the prescribed procedure and performs the preparation work (preparation step S104).
[0027] In this preparation step, the display device 14 displays the dispensing instruction data for RP units or administration units that were prepared in the previous audit step as selectable, and the preparer uses the operation input device 15 to select the appropriate dispensing instruction data corresponding to the dispensing instruction slip in tray 100 while confirming the dispensing instruction data. This selection may be made, for example, by having the reader 11 read the dispensing instruction slip on tray 100, or it may be made by the dispenser using the operation input device 15. After such selection is made, the preparer takes the designated drug M from the tray 100 and has the reader 11 read the regular code 70 of drug M (step S105). Then, the dispensing instruction data for the drug M is displayed on the display device 14 (step S106). In the following explanation, we will specifically illustrate a case where, as shown in Figure 5(a), the prescription data instructs a prescription for 500 mL of physiological saline solution and 0.125 g (125 mg) of fluorouracil injection. In this case, the dispensing instruction data instructs to withdraw only 2.5 mL from the supply container 6 containing 250 mg / 5 mL of 5-FU injection into a syringe.
[0028] The preparer first places the supply container 6 of fluorouracil injection solution, which is drug M, taken out of tray 100, onto an electronic scale 12 and measures its weight (step S107). Here, the specification data such as the amount of drug M contained in the drug handled by the dispensing support system 10 is pre-registered in the drug master in the aforementioned database 80, and the dispenser can check from the specification data displayed on the display device 14 whether the supply container 6 contains the prescribed amount of drug M required for the prescription. Furthermore, the display device 14 displays the target amount of drug M to be extracted from the supply container 6, as will be described later. The preparer prepares the medication according to a predetermined procedure based on the dispensing instruction data visually displayed by the display device 14 (step S108). Specific examples of this dispensing instruction data may be those described in, for example, Japanese Patent No. 5828832.
[0029] The electronic scale 12 measures the change in weight of the supply container 6 before and after the preparation step. The information processing device 13 records the measured change in weight of the supply container 6 as the amount withdrawn from the supply container 6 (step S109). At this time, the display device 14 prompts the preparer to place the supply container 6, after the target amount has been extracted, onto the electronic scale 12.
[0030] When the preparer withdraws the injectable drug from the supply container 6 using the manual inhalation device 8 in accordance with the instructions and places the supply container 6 on the electronic scale 12, the dispensing support system 10 measures the weight and determines whether it falls within a predetermined range (e.g., ±5%) from the withdrawal target value calculated in step S107. For example, in the audit screen example shown in Figure 5(b), the target volume of 2.50 mL and target weight of 2.62 g, corresponding to the target ingredient amount of 125 mg, are displayed, and as a record of the preparation results in the preparation step, the extracted amount is displayed as a result weight of 2.5 g and a result volume of 2.39 mL. Preferably, the dispensing support system 10 also records the person who performed the preparation, the time of preparation, and the contents of the preparation. Alternatively, the dispensing support system 10 may be equipped with a camera or similar imaging unit to record the preparation work as image data.
[0031] The injectable drug Mb, prepared in the manual inhalation device 8 in this manner, is placed on a tray 100 along with the supply container 6 and brought to the final inspection table 5 located near the dispensing table 4 (step S110). In this example, we describe a case where the final audit is conducted at the final audit table 5, separate from the dispensing table 4. However, this configuration is not limited to this example. The final audit may be conducted at the dispensing table 4 by a final auditor other than the preparer, or the audit may be conducted in a completely different location.
[0032] In step S110, the final auditor determines whether the preparation of the injectable drug Mb in tray 100 matches the prescription data. Specifically, the dispensing support system 10 uses a display device 14 or monitor 17 to allow users to refer to the preparer, preparation time, and preparation details of the prepared injectable drug Mb. The final auditor, for example, checks the preparer, preparation time, and preparation details of the injectable drug from the screen shown in Figure 5(b) on the monitor 17, which is a display device installed on the final audit desk 5, and also checks the actual supply container 6 and manual inhalation device 8 contained in the tray 100 to confirm that the prescribed order information and the preparation record match. If the final auditor determines that the preparation performed in the preparation step matches the prescription data, the final auditor records that the audit was successfully conducted using the operation input device 15. The information processing device 13 records the final audit details (the final auditor in charge, the time of the audit) on the condition that such an operation has been performed.
[0033] In conventional preparation methods and dispensing support systems, mechanisms were in place to confirm that injectable drugs were prepared correctly by recording the preparation details of the preparer and the audit time of the final auditor.
[0034] In this embodiment, in addition to the above configuration, if a certain amount of medication remains in tray 100 for which the medication management flag is ON on the medication master, it is possible to perform medication management for such medication. For example, in the prescription data shown in Figures 5(a) and 5(b) above, the prescribed amount of 250 mg / 5 mL of 5-FU injection is 125 mg (0.5 vials). As a result, 2.61 mL of residual drug remains inside the supply container 6, after deducting the resulting volume of 2.39 mL.
[0035] Traditionally, leftover medications like these were discarded, but with rising medical costs and disposal expenses, methods for reusing them while ensuring sufficient safety are being explored in recent years.
[0036] In the final audit step S110, if the dispensing support system 10 finds a drug in the prescription data whose prescribed quantity is not an integer value, and if the drug has the remaining drug management flag ON in the drug master data, the dispensing support system 10 displays the remaining quantity print button 71 on the monitor 17 for the remaining drug N1 (step S111). At this point, step S111 is a medication management confirmation step to check whether there are any medications among the prescribed medications that meet the criteria for medication management remaining. When the remaining amount print button 71 is pressed, the remaining drug amount calculation means 54 calculates the remaining drug N1 as 2.61 mL, which is obtained by subtracting the resulting volume of 2.39 mL from the standard amount (5 mL) of drug M registered in the drug master. In this way, the drug corresponding to the regular code 70 read in the preparation step is displayed as the remaining drug along with audit information. The dispensing support system 10 proceeds to the remaining medication registration process when the final auditor presses the remaining quantity print button 71 (step S112). Furthermore, if in step S111 there are no medications with the remaining medication confirmation flag turned ON, or if all prescribed quantities are integer values and no medication remains, or if any remains are in the form of a negligible amount below the prescribed quantity, the final audit will be completed as usual.
[0037] In the remaining medication registration process of step S112, the dispensing support system 10 displays a remaining medication registration screen as shown in Figure 6. Furthermore, at this time, the dispensing support system 10 may also check the expiration date and storage conditions of the remaining medication N1 registered from the drug master and display them on the remaining medication registration screen along with the dosage. The final auditor, on the remaining medication registration screen, uses the input device 15 to check the medication for which they want to print a remaining medication label (for example, remaining medication N1 displayed as 5-FU injection 250 mg / 5 mL) and presses the print button 72. This dosage information may be manually entered and rewritten by, for example, the final auditor, after confirming the dosage from the actual remaining amount in the supply container 6. Furthermore, even when the prescribed amount is an integer and nominally no leftover medication is generated, there may be cases where it is desirable to use a small amount of remaining medication. In such cases, the user may press the new registration button 73 on the leftover medication registration screen displayed in step S112 and input the necessary information such as dosage, drug name, and expiration date using the operation input device 15 on the new leftover medication registration screen shown in Figure 7. Newly registered remaining medications may also be displayed on the remaining medication registration screen. The operation performed by the final auditor in step S112 is the remaining medication registration operation.
[0038] The identification number issuing means 60 in the information processing device 13 issues a unique lot number for the remaining medication N1 that has been checked on the remaining medication registration screen (step S113). When the print button 72 is pressed in step S113, the printer 61 prints a sticker 63 containing a lot number and display code 62, for example as shown in Figure 8, in a manner that allows it to be attached to the outside of a sealing member 90 such as a zipper (step S114). At this time, the lot number is a unique identification number for the remaining medication N1, and a display code 62 that can be read by the reader 11 is issued in a one-to-one correspondence with this identification number.
[0039] The final auditor concludes the process for tray 100, marking it as audited after the final audit is complete. Furthermore, any remaining medication N1 that is subject to medication management is placed in a sealing member 90 along with the supply container 6, and a seal 63 printed in step S114 is attached to the sealing member 90, which is then placed in a designated storage location such as a safety cabinet or storage room.
[0040] In this embodiment, the dispensing support system 10 calculates the amount to be extracted according to the weight measured by the electronic scale 12 in the preparation step, and calculates the amount of remaining medication N1 at the time of final audit by subtracting the amount to be extracted from the standard amount registered in the drug master. The amount of drug registered in the drug master may be the prescribed amount (for example, 5.0 mL for 5-FU injection 250 mg / 5 mL), but in some cases it may be more appropriate to use the excess amount actually filled into the supply container 6, which is greater than the prescribed amount. In this embodiment, the remaining drug amount calculation means 54 has only been described in the case where the remaining drug amount is calculated using a standard amount as the specified amount, but the excess filling amount may also be used as the standard amount. In either case, the specified amount and the overfill amount can be determined by having the reader 11 read the official code 70, such as the barcode or YJ code of the drug, from the drug manufacturer, and can be registered in the drug master in advance.
[0041] Now, using Figure 9, we will explain the process for using leftover medications N1 to N5, which have been managed according to the above procedure and are in storage.
[0042] Furthermore, since the basic procedures in these processes are the same as those in Figures 3 to 8, explanations will be omitted as appropriate. The actions taken up to the previous audit step S203 are the same as those already described, so we will omit further explanation.
[0043] In step S204, if there are usable remaining medications in the prescription data, the dispensing support system 10 displays the remaining medications N1 to N5 as a list of usable remaining medication data at the bottom of the order information, along with the names of the medications to be used, as shown in shaded areas in Figure 10.
[0044] This section explains the case where the remaining drug N1 is used instead of the new drug N. When the preparer visually confirms that there are usable remaining medications N1 and N2 in step S204, he brings the remaining medications N1 and N2 to the dispensing counter 4 and reads the display code 62 on the sticker 63 attached to the remaining medication N1 using the reader 11 (step S205). If the display code 62 is read, the dispensing support system 10 changes the status of the remaining medication N1 in the remaining medication data to "in use," and adds information such as the dosage and ingredient amount of the selected remaining medication N1 to the prescription data. Similarly, the preparer reads the label code 62 on the sticker 63 attached to the remaining medication N2 using the reader 11 (step S205). Each remaining dose of medication N1 and N2 is managed by a display code 62 along with a unique lot number, as previously mentioned. Therefore, by reading the display code 62 using the reader 11, the dosage of remaining medication N1 and N2 can be easily determined.
[0045] The dispensing support system 10 determines whether the dosages of remaining medication N1 and N2, read from the display code 62, meet the prescribed amount (step S206). If the amount of remaining medication N1 read in step S205 is equal to the prescribed amount, the display device 14 replaces the row for medication N with the remaining medication N1 and displays it as shown in Figure 11 (S208). Furthermore, if the prescribed amount is not met, the display is changed to indicate that the amount of the selected remaining medication N2 is deducted from the prescribed amount and used from the new medication N, as shown in column N2 of Figure 11, and a message indicating the use of the remaining medication is displayed (S207). Figure 11 shows more specifically the case where a portion of 5-FU injection 1000 mg / 20 mL is used, specifically the case where a remaining dose of 0.61 mL (N2) is used. At this point, since 0.61 mL / 20 mL = 0.0305 (V), the remaining 0.9695 (V) will be covered by the new drug N contained in tray 100. If the selected amount of remaining medication does not exceed the required amount from the prescription data, the dispensing support system 10 displays both the amount to be prepared (required amount minus the selected amount of remaining medication) and the amount to be prepared for the selected amount of remaining medication.
[0046] Furthermore, in step S206, the dispensing support system 10 also determines whether the remaining medication N1, registered in the display code 62 from the drug master, has met its expiration date. For example, if the remaining medication N1 has not reached its expiration date, the display device 14 will display a message indicating that it has expired, as shown in Figure 12.
[0047] After the preparation operator selects the remaining drug N1 to be used by reading the display code 62, the preparation operator removes the remaining drug N1 from the sealing member 90 and has the reader 11 read the regular code 70 of the supply container 6 for the remaining drug N1 (step S209). The dispensing support system 10 can verify whether the drug information at the time of registering the remaining medication was correct by reading the display code 62 in step S205 and then reading the regular code 70 of the remaining medication N1 in step S209. With this configuration, the display code 62, which is the remaining medication code, and the regular code 70, which indicates the drug information, are double-checked, thus preventing risks such as the misuse of medication when using remaining medication.
[0048] Furthermore, when the display code 62 is read, the dispensing support system 10 displays that the drug corresponding to the display code 62 is in use. This prevents multiple dispensing agents from each retrieving the same remaining medication if they wish to use it, thus contributing to increased efficiency in the dispensing process. Furthermore, if the use of remaining medication N1 is to be discontinued at dispensing counter 4, the display code 62 of the remaining medication N1 that was read can be read again by the reader 11 of dispensing counter 4, thereby releasing the status of remaining medication N1 being used and canceling the reservation for its use. In this way, by reading the display code 62, it is possible to easily decide whether or not to use the remaining medication N1. Furthermore, if the display code 62 of the remaining medication N1 in use is read by a reader 11' located on another dispensing counter 4', it is preferable that the display device 14' on that dispensing counter 4' displays a message indicating that the remaining medication N1 is in use, as shown in Figure 13.
[0049] In this way, when using the remaining medications N1 and N2, the dispensing instruction data is displayed on the display device 14 in the same way as in step S106 (step S210). Specifically, for example, when a prescription data like the one shown in Figure 11 is used to prescribe 500 mL of physiological saline and 1.250 g (1250 mg) of fluorouracil injection, the dispensing instruction data will instruct the dispenser to withdraw 5 mL from the remaining medication N1 supply container 6 containing 250 mg / 5 mL of 5-FU injection into a syringe, to withdraw 19.39 mL from the 5-FU injection 1000 mg / 20 mL supply container 6 (20 × 0.9695 = 19.39) into a syringe, and to withdraw 0.61 mL from the remaining medication N2 supply container 6, as shown in Figure 14. Furthermore, when any remaining medication (N1, N2) is used in the preparation work, a remaining medication use mark 65 will be displayed on the display screen of the display device 14 to indicate that the remaining medication has been used. The preparer, in accordance with the dispensing instruction data, withdraws the drug from the supply container 6 using a manual inhaler 8, and places the supply container 6 on the electronic scale 12 before and after the withdrawal, so that the dispensing support system 10 records the amount withdrawn (step S211). The operation of the dispensing support system 10 during this preparation operation is the same as in steps S108 to S109. Furthermore, if the preparer postpones such an operation for any reason during the preparation process, it is preferable that no additional remaining medication can be added. If an attempt is made to read the display code 62 for the remaining medication N3 into a prescription data that is currently on hold, it is preferable that a message is displayed indicating that the remaining medication cannot be selected because it is on hold.
[0050] Now, after performing these preparation steps, a final audit is also performed in this embodiment (step S214). If any leftover medication is used in the preparation process, a leftover medication usage mark 65 will be displayed on the final audit screen shown on monitor 17 in step S214, as shown in Figure 15, indicating that leftover medication was used. In the example described above, as a result of using the remaining medications N1 and N2, the tray 100 should contain an unopened, unused medication and a supply container 6 with 20-19.39=0.61 mL of medication remaining.
[0051] The final auditor then registers the newly generated remaining medication as a new remaining medication N6, following the same procedure as in steps S112 to S114. Specifically, the identification number issuing means 60 issues a unique lot number, which is an identification code, for a new remaining drug N6 with a dosage of specified amount - extracted amount = 20 - 19.39 = 0.61 mL, and the printer 61 prints a seal 63 that includes the lot number and display code 62. Furthermore, if, for example, the aforementioned unopened and unused drug is also to be treated as remaining drug, the reader 11 can read the regular code 70 for the unused drug, allowing the identification number issuing means 60 to similarly issue a unique lot number and register it as 20 mL of remaining drug. The final auditor places the remaining medication N6 into a new sealed container 90, attaches a seal 63 to the outside, and moves it to the storage location.
[0052] By repeating these work procedures, any leftover medication generated during the preparation process can be managed within the cleanroom, and the dispensing support system 10 can manage it by lot number. This allows for the effective use of leftover medication while ensuring safety, even in preparation processes that include manual work.
[0053] As described above, the dispensing support system 10 in this embodiment includes an information processing device 13 which has a drug master that stores data including drug name and prescribed amount for various drugs, and a display control means 40 which retrieves the drug name and prescribed amount from the drug master based on prescription information and creates display data related to the dispensing work of the dispenser, including the drug name, prescribed amount and prescribed amount, a display device 14 which can display the display data so that the dispenser can see it, a reader 11 which reads the regular code 70 of the drug supply container 6 when dispensing work is performed using drugs, and an electronic scale 12 which can measure the weight of the supply container 6 containing drugs during dispensing work. Furthermore, the dispensing support system 10 includes a remaining medication confirmation means 50 that, after the dispensing work is completed, displays the medications that meet predetermined conditions among the medications used, along with audit information, as remaining medications corresponding to the regular code 70 read during the dispensing work, and registers the remaining medications in the drug master through a remaining medication registration operation, and an identification number issuing means 60 that issues a unique identification number for the medications for which the remaining medication registration operation has been performed.
[0054] Furthermore, in this embodiment, the dispensing support system 10 may also confirm the use of remaining medication by reading the display code 62 in addition to the regular code 70 using the reader 11 when the dispensing pharmacist uses medication that has already been registered as remaining medication during the dispensing process. With this configuration, it is possible to determine whether the official code 70 printed on the outer box of the medication matches the information on the remaining medication assigned at the time of the final audit, thereby eliminating the risk of mix-ups and enabling the safe use of remaining medication.
[0055] Furthermore, in this embodiment, the reader 11 has a means 56 for determining whether the expiration date of the remaining medication N1 is within a predetermined period, provided that the display code 62 has been read. With this configuration, the expiration date can be checked simultaneously by reading the display code 62, allowing for safe use of remaining medication without increasing the complexity of operation.
[0056] In this embodiment, the identification number issuing means 60 includes a printer 61 that prints a display code 62 in a manner that allows it to be affixed to the outside of the sealing member 90 that seals the supply container 6. With this configuration, the reader 11 can check the drug name, remaining amount, and expiration date of the remaining drug N1 from the outside while it is sealed, thus allowing for safe use of the remaining drug while minimizing deterioration and contamination.
[0057] In this embodiment, the display device 14 indicates to the pharmacist that the medication is in use, provided that the display code 62 is read by the reader 11. With this configuration, even in environments where multiple dispensing stations are used in combination, leftover medication can be safely utilized without multiple people having to compete for it.
[0058] Furthermore, in this embodiment, the reader 11 has a prescription quantity confirmation means 57 that, on the condition that multiple different display codes 62 have been read, confirms whether the total amount of drugs corresponding to the multiple display codes 62 does not exceed the prescribed amount of drugs included in the prescription information. With this configuration, the dispensing support system 10 can minimize the increase in leftover medication.
[0059] In this embodiment, the display device 14 displays a list of medications registered as remaining medications from the prescription information, so that the pharmacist can see them. The dispensing support system 10 determines the use of the registered remaining medications when the pharmacist selects them using the operation input device 15.
[0060] In this embodiment, the device also includes a remaining drug amount calculation means 54 that calculates the remaining drug amount from the recognition code 62 read by the reader 11 and the amount extracted by the electronic scale 12 and the specified amount during the preparation step. The remaining drug amount calculated by the remaining drug amount calculation means 54 is issued in association with the amount of remaining drug determined by the remaining drug determination means 50 and the display code 62. With this configuration, the amount of remaining medication can be read using a common operation during the final audit, allowing the amount of remaining medication to be recorded in conjunction with the amount sampled during the preparation process without increasing workload.
[0061] As described above, in this embodiment, only liquid formulations have been explained for the purpose of describing the management of remaining medication. However, the dispensing support system 10 can be used not only for liquid formulations but also for injectable drugs that are prepared by dissolving a freeze-dried agent using a solvent.
[0062] Although preferred embodiments of the present invention have been described above, the present invention is not limited to these specific embodiments, and various modifications and changes are possible within the scope of the spirit of the invention as described in the claims, unless otherwise specifically limited in the above description.
[0063] For example, in this embodiment, a dispensing support system 10 is shown as a system to which a reader 11, an electronic scale 12, an information processing device 13, a display device 14, etc., are connected. However, for example, these systems may be executed by a program that performs each of the means described above in steps S101 to S215, or by various storage media in which such programs are stored. Furthermore, the terminals and devices used to perform these tasks may be located in separate locations and connected to each other via a network.
