Description

  The present invention is based on the premise that blood collection management (blood collection traceability) for managing the state of use (from blood collection to examination / disposal) of blood collection tubes distributed to medical institutions is performed. The present invention relates to a blood collection tube life cycle monitoring system and a blood collection tube life cycle monitoring method for monitoring whether leakage or loss has occurred.

  In hospitals and other medical institutions, a predetermined blood test is performed based on the patient's symptoms, and the patient is diagnosed based on the test result. Blood collected from a patient is stored in a container called a blood collection tube. The blood collection tube is distributed in advance from the inspection institution to the medical institution. In a medical institution, blood is collected in a blood collection tube of a type corresponding to an inspection item, and an inspection request form is prepared and sent to the inspection institution. The testing institution collates the sent blood collection tube with the test request form, performs a blood test specified in the test request form, and reports the test result to the hospital. In this way, a series of processing is performed on the blood collection tube from distribution to a medical institution, blood collection, transport to the inspection institution, arrival confirmation at the inspection institution, blood test, storage, and disposal.

  Conventionally, a system that realizes traceability of a blood collection tube by attaching a non-contact type wireless tag (RF tag) to the blood collection tube is known (see, for example, Patent Document 1 and Patent Document 2).

International publication WO2010 / 119909 specification Japanese Patent No. 5354509

  Hereinafter, a blood collection life cycle monitoring system and a blood collection life cycle monitoring method according to embodiments of the present invention will be described with reference to the drawings. In all the drawings for explaining the embodiments, common constituent elements are denoted by the same reference numerals, and repeated explanation is omitted.

FIG. 1 shows an exemplary configuration of a blood collection life cycle monitoring system 1 according to an embodiment of the present invention.
The blood collection life cycle monitoring system 1 includes a medical institution terminal 110, a testing institution terminal 210, a traceability server 310, and a monitoring server 350. The medical institution terminal 110, the inspection institution terminal 210, the traceability server 310, and the monitoring server 350 are connected to the network 400, and can transmit and receive data to and from each other via the network 400. However, these may transmit and receive data via a dedicated line.

The medical institution terminal 110 is installed in the medical institution 100. Although only one medical institution is shown in FIG. 1, a plurality of medical institutions may be included in the blood collection tube life cycle monitoring system 1.
A card reader 111 is connected to the medical institution terminal 110. The card reader 111 reads information recorded on the wireless tag from the blood collection tube 10 with the wireless tag.
In the medical institution 100, a doctor creates a test request form, collects blood from the patient under the direction of the doctor, and collects a sample collected from the patient in the blood collection tube 10 with a wireless tag distributed from the inspection institution 200. The medical institution terminal 110 reads information with the card reader 111 from the wireless tag of the blood collection tube 10 with the wireless tag before and after blood collection. The medical institution terminal 110 transmits information read by the card reader 111 to the traceability server 310 installed in the data center 300 via the network 400. The traceability server 310 stores the received information in the traceability table 330 of the traceability DB (database) 320.

  The inspection organization terminal 210 is installed in the inspection organization 200. A card reader 211 is also connected to the inspection organization 200. The card reader 211 reads information from the wireless tag of the blood collection tube 10 with the wireless tag collected from the medical institution 100. The inspection organization terminal 210 also transmits information read by the card reader 211 to the traceability server 310. The traceability server 310 stores the received information in the traceability DB 320 traceability table 330.

The traceability server 310 and the monitoring server 350 are installed in the data center 300.
The traceability server 310 has a traceability DB 320. The traceability DB 320 stores the traceability table 330 of FIG. The traceability server 310 tracks each process in the life cycle of the radio tagged blood collection tube 10 and records trace information including the time and position of the radio tagged blood collection tube 10 at each process in the traceability table 330. .

The monitoring server 350 includes a determination unit 351 and a monitoring DB 360. The monitoring DB 360 stores a determination information table 370 in FIG. 4, a grouping determination information table 380 in FIG. 6, and a monitoring status table 390.
The function of the determination part 351 is implement | achieved when CPU (Central Processing Unit) of the monitoring server 350 runs the determination program memorize | stored in the main memory.
The determination unit 351 analyzes the state of the blood collection tube 10 with the wireless tag recorded in the traceability table 330 based on the conditions recorded in the determination information table 370 and the grouping determination information table 380 at a constant period, and Determine whether there is a risk of processing omission or loss. The determination unit 351 stores the determination result in the monitoring status table 390.
In addition, the determination information table 370 and the grouping determination information table 380 record messages that the determination unit 351 notifies the medical institution 100 and the inspection institution 200 and contents of predetermined processing performed by the determination unit 351. The content of the message prompts confirmation of the location of the blood collection tube 10 with the wireless tag and confirmation of the processing status for each condition because there is a risk of processing omission or loss. When the determination unit 351 determines that there is a risk of sample processing omission or loss, the determination unit 351 transmits the message to the medical institution 100 and the inspection institution 200. When the person in charge of the medical institution 100 or the inspection institution 200 reads the message, it is possible to reduce the possibility of sample processing omission or loss.

In the present embodiment, the determination unit 351 groups the wireless blood collection tubes 10 with wireless tags according to the determination for each wireless blood collection tube 10 with a wireless tag and whether there is a risk of sample processing omission or loss, and the blood collection date and time or the requesting medical institution. Two types of judgments are made.
In the determination for each first radio tagged blood collection tube 10, the determination unit 351 determines based on the conditions recorded in the determination information table 370 of FIG. 4. In the determination information table 370, the waiting time until the next process is recorded for each process in the life cycle of the blood collection tube 10 with the wireless tag. When the determination unit 351 determines whether or not there is a risk of processing omission or loss, the time elapsed from the wireless tag reading time in the process last registered in the traceability table 330 for each sample (the blood-collecting tube with a wireless tag 10). If the waiting time is exceeded, it is determined that there is a risk of sample processing omission or loss.

In the determination to be performed by grouping the wirelessly tagged blood collection tubes 10 at the second blood collection date and time, the requesting medical institution, etc., the determination unit 351 makes a determination based on the conditions recorded in the grouping determination information table 380 in FIG. . In the grouping determination information table 380, grouping conditions for grouping the radio tagged blood collection tubes 10 are stored. The grouping condition is, for example, a unit in which the examination of a sample such as a medical institution, examination item, and blood collection date / time advances simultaneously. When determining whether there is a risk of processing omission or loss, the determination unit 351 checks the processing status of each process in units of groups, and if the blood collection tube 10 with a wireless tag that is not in the same processing status within the group is lost or lost Judge that there is a fear of.
For example, when the wireless blood collection tube 10 with a wireless tag, which has been 10 at the request of the medical institution 100, is out of the group at the time of arrival confirmation at the inspection institution 200 (for example, when arrival confirmation of only one sample is not performed). In addition, the determination unit 351 determines that there is a risk of sample processing omission or loss.

  In FIG. 1, the traceability server 310 and the monitoring server 350 are separated. However, the functions of both servers may be realized by a single computer, and the determination unit 351 of the monitoring server 350 stores the traceability DB 320 and the monitoring DB 360. Any physical configuration can be used as long as the stored information can be acquired. The processing result of the determination unit 351 may be output to the output unit of the monitoring server 350 or may be transmitted to the inspection organization terminal 210.

FIG. 2 shows an example of the life cycle of the blood collection tube 10 with a wireless tag.
In each step of the life cycle shown in FIG. 2, data is read from the wireless tag by the card reader, and the trace information is stored in the traceability table 330 of the traceability DB 320.
First, the various blood collection tubes 10 with a wireless tag are distributed from the inspection institution 200 to the medical institution 100 (S101). Next, blood is collected from a patient by a medical staff at the medical institution 100, and the sample is collected in the blood collection tube 10 with a wireless tag (S102). The blood collection tube 10 with the wireless tag collected at the medical institution 100 is collected by a person in charge of collection at the inspection institution 200 and transported to the inspection institution 200. When the person in charge of collection confirms the blood collection tube 10 with the wireless tag at the medical institution 100, the wireless tag of the blood collection tube 10 with the wireless tag is read and the blood collection tube 10 with the wireless tag is confirmed (S103). When the blood collection tube 10 with the wireless tag collected by the person in charge of collection at the inspection organization 200 is transported to the inspection facility of the inspection organization 200 and arrives, the arrival confirmation of the blood collection tube 10 with the wireless tag is performed and is there no loss? Confirmed (S104). Then, the wireless tag is read by the card reader in order to confirm the inspection item and the sample (collection tube with wireless tag 10) before the inspection in the inspection facility of the inspection organization 200 (S105). After the inspection, the wireless tag-attached blood collection tube 10 is stored for a predetermined period in preparation for reexamination (S106). The sample (wireless blood collecting tube 10) that has passed the predetermined storage period is discarded (S107).

FIG. 3 shows an example of trace information managed by the traceability table 330.
The trace information includes a blood collection tube ID 331, a reading time 332, a reading step 333, a patient name 334, a blood collection amount 335, a test item 336, and a medical institution 337.
The blood collection tube ID (Identifier) 331 is identification information for uniquely identifying the blood collection tube 10 with a wireless tag.
The reading time 332 indicates the time at which the wireless tag of the blood collection tube 10 with the wireless tag is read by the card reader.
A reading step 333 indicates a business process in which the wireless tag of the blood collection tube 10 with a wireless tag is read by a card reader.
The patient name 334 indicates the name of the patient of the sample collected in the blood collection tube 10 with the wireless tag.
A blood collection amount 335 indicates a blood collection amount collected in the blood collection tube 10 with a wireless tag.
The examination item 336 indicates an examination item to be performed on the sample collected in the blood collection tube 10 with the wireless tag.
The medical institution 337 stores information that can uniquely identify the medical institution that has collected blood.
In the blood collection tube traceability, in each step of the life cycle of the wireless blood collection tube 10 with a wireless tag shown in FIG. 2, the medical institution terminal 100 or the inspection institution terminal 210 reads the wireless tag with a card reader in the medical institution 100 or the inspection institution 200. The read information is transmitted to the traceability server 310. The traceability server 310 registers the trace information shown in FIG. 3 in the traceability table 330 of the traceability DB 320.

FIG. 4 shows an example of the configuration of the determination information table 370.
The determination unit 351 uses the determination information table 370 when determining for each blood collection tube 10 with a wireless tag whether there is a risk of sample processing omission or loss.
The determination information table 370 includes items of a determination condition ID 371, a step 372, a next step 373, a waiting time 374 until the next step, and a processing content 375.
The determination condition ID 371 is identification information that uniquely specifies the determination condition.
Step 372 shows a step of the life cycle shown in FIG.
A next step 373 shows a step performed after the step 372.
The waiting time 374 until the next process indicates a time limit from when the process 372 is registered in the traceability table 330 to when the next process 373 is registered. If the next step 373 is not registered in the traceability table 330 even after the standby time 374 until the next step is exceeded, the determination unit 351 determines that there is a risk of sample omission or loss.
The processing content 375 indicates a message displayed on the display of the monitoring server 350 or a predetermined process to be executed by the determination unit 351 when the determination unit 351 determines that there is a risk of sample omission or loss.

FIG. 5 shows an example of determination processing for each wireless tag-attached blood collection tube 10 by the determination unit 351.
First, the determination unit 351 acquires the latest processing status of each radio-tagged blood collection tube 10 from the traceability table 330 (S201).
Next, the determination unit 351 searches the determination information table 370 for each radio tagged blood collection tube 10 and determines whether the acquired latest processing status matches any of the determination conditions (S202). For example, in FIG. 3, the trace information of blood collection ID 331 = “blood collection ID 4” is registered only until “blood collection B” in the reading step 333. In this case, in FIG. 4, the step 372 of the determination condition ID 371 = “determination condition ID 2” is “blood collection B” and matches the reading step 333. Since the waiting time 374 until the next process of the determination condition ID 371 = “determination condition ID 2” is set to 50 minutes, the determination unit 351 stores the traceability table 330 after 10:51 on January 1, 2014. When monitoring is performed, the determination unit 351 determines that there is a risk of sample processing omission or loss (S202: Yes).
If it is determined that there is a risk of sample omission or loss, the determination unit 351 executes the processing set in the processing content 375 of the determination condition ID 371 (S203). Since the processing content 375 of the determination condition ID 371 = “determination condition ID 2” is set to “display next message on the monitoring server“ warning! *** ””, the determination unit 351 determines “warning! ***”. ** ”is displayed on the display of the monitoring server 350 or the like. As a result, the user of the monitoring server 350 is prompted to perform operations such as confirmation of the blood collection tube 10 with the wireless tag.
Next, the determination unit 351 checks whether or not the determination process has been completed for all the blood-tagged blood collection tubes 10 acquired in step S201 (S204). When the determination process for all the blood-tagged blood collection tubes 10 has not been completed (S204: No), the determination unit 351 repeatedly executes steps S201 to S204. When all the blood collection tubes have been subjected to the determination process (S204: Yes), the determination unit 351 waits until the next regular monitoring time, and repeats from step S201 when the monitoring time is reached (S205).

FIG. 6 shows an example of the configuration of the grouping determination information table 380.
The determination unit 351 uses the grouping determination information table 380 when grouping the blood collection tubes 10 with the wireless tag to determine whether there is a risk of sample processing omission or loss.
The grouping determination information table 380 includes items of a grouping ID 381, a grouping name 382, a grouping condition A 383, a grouping condition B 384, a grouping condition C 385, a determination condition 386, and a processing content 387.
The grouping ID 381 is identification information that uniquely identifies a grouping condition.
The grouping name 382 indicates the name of the grouping. The grouping name 382 is for making it easy for a person to distinguish the grouping contents.
The grouping condition A383, the grouping condition B384, and the grouping condition C385 are conditions for grouping the blood collection tubes 10 with the wireless tag. The determination unit 351 groups the blood-labeled blood collection tubes 10 having the same grouping condition A383, grouping condition B384, and grouping condition C385 into one group when the regular monitoring is executed. For example, with grouping ID 381 = “grouping ID 1”, the blood collection tubes 10 with the wireless tag having the same medical institution, examination item, and blood collection date are grouped into one group. In addition, with grouping ID 381 = “grouping ID 2”, the blood collection tubes 10 with the wireless tag having the same test item and blood collection date are grouped into one group. The blood collection date is, for example, the reading time 332 when the reading step 333 is blood collection A or blood collection B in the traceability table 330 of FIG. 3, and the blood collection date is the date to which the reading time 332 belongs.
The determination condition 386 indicates a condition in which it is determined that there is a risk of processing omission or loss among the radio-labeled blood collection tubes 10 grouped into one group. An example of the determination condition 386 is that the wireless tag-attached blood collection tubes 10 of the same group are in two or more reading steps 333, and the reading time 332 of the wireless tag-attached blood collection tube 10 in the final reading step 333 and the monitoring server 350 are included. For example, the difference from the monitoring time by exceeds the predetermined time limit.
The processing content 387 indicates a message displayed on the display or the like of the monitoring server 350 by the determination unit 351 or a process executed by the determination unit 351 when it is determined that there is a risk of processing omission or loss. The content of the processing content 387 is arbitrary, and it is possible to set processing content according to grouping conditions and determination conditions 386 such as cooperation with another system, lighting of a patrol lamp and warning by mail. In FIG. 6, the grouping conditions specifically shown are up to three (grouping condition A383, grouping condition B384, and grouping condition C385), but the number can be arbitrarily set.

FIG. 7 shows an example of a process in which the determination unit 351 groups the wireless tag-attached blood collection tubes 10 to determine whether there is a risk of sample processing omission or loss.
The determination unit 351 acquires the grouping condition A383, the grouping condition B384, and the grouping condition C385 from the grouping determination information table 380 of the monitoring DB (S301). Next, the determination unit 351 groups the wireless-tagged blood collection tubes 10 under the acquired grouping conditions based on the trace information in the traceability table 330 of the traceability DB 320 at regular intervals (S302).
And the determination part 351 confirms whether the reading process 333 of the blood collection tube 10 with a radio tag differs for every group in a group (S303). When there is a different wireless tag-attached blood collection tube 10 (S303; Yes), the determination unit 351 determines whether the difference between the reading time 332 and the monitoring time of each wireless tag-attached blood collection tube 10 in the final reading step 333 is a predetermined limit. It is confirmed whether it is out of time (S304).

As a result of the confirmation, if it is within the predetermined time limit (S304: No), the determination unit 351 determines that the corresponding group is in business processing. When it is outside the predetermined time limit (S304: Yes), the determination unit 351 determines that a plurality of processes are not present in the group because of the business process, and the grouped wireless tag-attached blood collection tubes 10 are used. If the reading step 333 corresponds to a step in the previous stage of the life cycle, it is determined that there is a risk of processing omission or loss. Then, the determination unit 351 executes the processing set in the item of the processing content 387 (S305).
Next, the determination unit 351 confirms whether the processing from step S303 to step S305 has been executed for each grouping ID 381 (S306). If there is an unprocessed grouping condition (grouping ID 381) (S306: No), the determination unit 351 repeatedly executes steps S303 to S305. If all the grouping conditions have been checked (S306: No), the determination unit 351 waits for processing until the next regular monitoring execution (S307).

More specifically, the grouping and determination process are described below. When the trace information of the traceability table 330 shown in FIG. 3 is grouped under the grouping condition of grouping ID 381 = “grouping ID 1” in FIG. Divided. In this case, the blood collection tube ID1 and the blood collection tube ID2 are assigned to the group of the medical institution A, and the blood collection tube ID3 and the blood collection tube ID4 are assigned to the group of the medical institution B. Next, the examination items and blood collection date are grouped, and these are the same for the blood collection tube ID1 to the blood collection tube ID4. Therefore, the determination unit 351 allocates the blood collection tube ID1 and the blood collection tube ID2 group and the blood collection tube ID3 and the blood collection tube ID4 group (S302).
When the final reading step 333 of each wireless tag-attached blood collection tube 10 is confirmed, the blood collection tube ID1 is arrival confirmation, and the blood collection tube ID2 is collection A by the inspection organization. Since the blood collection tube ID 1 and the blood collection tube ID 2 are the blood collection tubes 10 with the wireless tag collected from the same medical institution A to the inspection organization, they are expected to be in the same process, but are registered in the traceability table 330. The reading process 333 is different (S303: Yes). However, the arrival confirmation process of the blood collection tube ID2 is being performed at the monitored timing, and the monitoring process may be performed immediately before the arrival confirmation of the blood collection tube ID2. Therefore, the final reading time 332 of the blood collection tube ID1 is compared with the time when the monitoring process is performed. When performing the comparison, for example, if the difference between the last reading time 332 and the monitoring time is within one hour (predetermined time limit), it is considered that the arrival confirmation process is being performed (S304: No). The time for determining that this process is being performed is merely an example, and can be arbitrarily set in the determination unit 351.
In this case, since the final reading time of the blood collection tube ID1 is “2014/1/1 12:00: 00”, if the monitoring time is after “2014/1/1 13:00:01”, the determination unit 351 Determines that the arrival confirmation processing of the group of blood collection tube ID1 and blood collection tube ID2 has been completed. Then, the determination unit 351 sends a message on the display of the monitoring server 350 that prompts the user to confirm that the blood collection tube 10 with a wireless blood collection tube ID2 for which the arrival confirmation process is not registered may be missed or lost. It is displayed (S305).

  Although the determination information table 370 in FIG. 4 and the grouping determination information table 380 in FIG. 6 are shown in a table format, a relational database is not indispensable for expressing and managing the determination conditions. Any format can be used as long as the conditions can be described in a regular format and can be analyzed by the determination unit 351.

As described above, according to the present invention, since the status of the blood collection tube (sample) is constantly monitored, it is possible to detect the processing omission or loss of the blood collection tube (sample) in a short time.
In this case, it is conceivable that the business process omission is skipped when sequentially processing a large number of blood collection tubes (RFID reading or the like), and the loss of the blood collection tube is misplaced when the blood collection tube is transferred. However, by constantly monitoring (checking) the update status of the trace information of the blood collection tube, it is possible to find a sample that is suspected of being missed or misplaced.
In addition, from the last update status registered in the traceability server, the location and date and time of the last confirmation of the blood collection tube, and information on the next process to be performed can be acquired at the same time. Etc. can be easily identified.
As a result, it is possible to prevent the occurrence of a situation in which the blood collection tube is not processed and a situation where the loss of the blood collection tube is not noticed, and the management quality of the blood collection tube can be improved.
