The present invention relates to a management device for managing a plurality of automatic analysis devices for analyzing a biological sample such as blood or urine and a request method for requesting preparation of reagent replacement and calibration/quality management processing for the plurality of automatic analysis devices in a clinical laboratory provided with the plurality of automatic analysis devices.
An automatic analysis device that analyzes a biological sample such as blood or urine has merits such as high reproducibility of analysis quality and quickness of analysis processing, and thus is indispensable for current diagnosis. There are a plurality of types of automatic analysis devices according to types of analysis. Examples include a colorimetric analysis device that performs biochemical analysis, an immune analysis device that analyzes an antigen or antibody in a sample using an antigen-antibody reaction, a coagulation analysis device that measures coagulability of blood, a blood cell counter that measures the number of blood cell components in blood, and the like. When analyzing a sample by the automatic analysis device, a pre-processing device that performs pre-processing such as centrifugation of blood or dispensing of the sample to prepare a plurality of child samples is also used. In a single hospital, examination center, or the like, a plurality of such automatic analysis devices and sample pre-processing devices are generally disposed and used in a clinical laboratory.
When a sample is analyzed by such an automatic analysis device, if a reagent runs out during the analysis, the analysis may be delayed and the diagnosis of a doctor may be delayed unless dealt with immediately. Patent Literature 1 discloses a technique of predicting an operation status of an automatic analysis device on the current day based on a past analysis history, and displaying a timing of replacing a reagent based on the predicted operation status and a remaining amount of the reagent on a screen.
Patent Literature 2 discloses a technique of measuring a quality management sample performed from a viewpoint of quality management of an analysis result, in which when the quality management sample is measured after replacement of a reagent bottle, analysis of a general sample cannot be performed during that time, and thus the quality management sample is held in a buffer, and when an amount of reagent is equal to or less than a set value, recommendation of measurement of the quality management sample for a standby reagent bottle is displayed on a screen or executed automatically.
In order to analyze a sample with an automatic analysis device, it is necessary to perform calibration for obtaining a calibration curve for calculating a concentration of the sample at the time of sample replacement or periodically, and QC measurement for evaluating whether a reagent is measured correctly. In the present application, hereinafter, processing for optimizing analysis by a reagent such as the calibration and the QC measurement is collectively referred to as calibration/quality management processing, and samples used in the calibration/quality management processing (for example, a calibrator used for the calibration or a QC sample used for the QC measurement) are collectively referred to as a calibration/quality management sample.
As disclosed in Patent Literature 2, since reagent replacement associates with the calibration/quality management processing, it is necessary to prevent time loss for the calibration/quality management processing. Patent Literatures 1 and 2 are both techniques for avoiding stagnation of analysis associated with the reagent replacement, and are techniques in units of automatic analysis device. Therefore, the automatic analysis device in Patent Literature 2 requires a buffer for holding the quality management sample.
On the other hand, in a clinical laboratory having a relatively large scale, a plurality of automatic analysis devices may be disposed, and the same reagent may be used in the plurality of automatic analysis devices. Since the reagent and the calibration/quality management sample each have an expiration date and affect an operation cost of the clinical laboratory, it is desirable to use the reagent and the calibration/quality management sample optimally in the entire clinical laboratory.
In the invention, the reagent replacement and the calibration/quality management processing for the plurality of automatic analysis devices are managed in units of clinical laboratory. At this time, by requesting a laboratory technician to prepare in consideration of a time required for preparation, it is possible to increase an operation rate of the automatic analysis device disposed in the clinical laboratory. Alternatively, the operation cost of the clinical laboratory can be optimized by appropriately selecting the reagent or the calibration/quality management sample of the clinical laboratory. Further, by increasing the operation rate of the automatic analysis device in units of clinical laboratory, a mechanism mounted on each automatic analysis device can be simplified, and the cost of the clinical laboratory can be reduced.
A management device according to an embodiment of the invention is a management device configured to manage a plurality of analysis devices in a clinical laboratory provided with the plurality of analysis devices that analyze a sample and a cabinet that stores a reagent used for measurement by the plurality of analysis devices or a calibration/quality management sample used for calibration/quality management processing of the reagent, the management device includes: a storage device configured to store a reagent information management table that manages a remaining amount of each of in-measurement reagents that are respectively installed on the plurality of analysis devices so as to be used for measurement, a reagent replacement preparation time management table that registers a first preparation time required for preparation for replacing the in-measurement reagent with a storage reagent stored in the cabinet and a calibration/quality management processing preparation time management table that registers a second preparation time required for preparation for calibration/quality management processing of the storage reagent; a reagent replacement preparation timing detection unit configured to detect a timing to start reagent replacement preparation, based on the remaining amount of the in-measurement reagent managed in the reagent information management table and the first preparation time registered in the reagent replacement preparation time management table; a calibration/quality management processing preparation timing detection unit configured to detect a timing to start calibration/quality management processing preparation, based on the remaining amount of the in-measurement reagent managed in the reagent information management table and the second preparation time registered in the calibration/quality management processing preparation time management table; and a notification person-in-charge determination unit configured to notify one of laboratory technicians working in the clinical laboratory of a request for the reagent replacement preparation or the calibration/quality management processing preparation upon receiving detection of a timing by the reagent replacement preparation timing detection unit or the calibration/quality management processing preparation timing detection unit.
According to the invention, it is possible to increase an operation rate of an automatic analysis device disposed in a clinical laboratory.
Other problems and novel features will become apparent from the description of the present description and the accompanying drawings.
In a first embodiment, in a situation where the number of times of remaining measurement of a reagent (in-measurement reagent) in an analysis device in a clinical laboratory is small and a reagent replacement time is close, a management device detects a reagent replacement timing at which reagent replacement should be started, a calibration preparation timing at which preparation for performing calibration on the replaced reagent (storage reagent) should be started, or a QC measurement preparation timing at which preparation for performing QC measurement on the replaced reagent (storage reagent) should be started, and notifies a laboratory technician of the reagent replacement timing, the calibration preparation timing, or the QC measurement preparation timing as a task. At this time, tasks are requested in an order of appropriate laboratory technicians in consideration of the tasks and locations currently engaged by the laboratory technicians working in the clinical laboratory.
The management device 102 communicates with the analysis devices 103 to 107, the pre-processing device 108, and terminals of the laboratory technicians via a network, and manages these devices. The analysis devices 103 to 107 are devices for performing the clinical examination, and may be operated independently or may be operated by combining a plurality of analysis devices. In this example, the analysis devices 106 and 107 operate independently, and the analysis devices 103, 104, and 105 operate in combination. The pre-processing device 108 is a device that automatically performs pre-processing for performing the clinical examination, is connected to the analysis devices 103 to 105 and 107, and transports a sample after the pre-processing to the analysis device. The management device 102 manages alarms generated by the analysis devices 103 to 107 and the pre-processing device 108 and alarms generated by the management device 102 itself. The reagent cabinets 109 and 110 store reagents necessary for the analysis device to perform the analysis. The calibrator cabinet 111 and the QC sample cabinet 112 store calibrators and QC samples for performing calibration and QC measurement in the analysis device. The laboratory technicians 114 to 117 are persons in charge who prepare the clinical examination in the clinical laboratory 101, operate the analysis devices, the pre-processing device, and the like, and each of the laboratory technicians 114 to 117 carries one or more terminals connected to the management device 102 via a network. After receiving a reagent replacement preparation notification, a calibration preparation notification, and a QC measurement preparation notification, the laboratory technicians 114 to 117 move to the front sides of the cabinets in order to take out the reagent, the calibrator, and the QC sample for the reagent replacement, the calibration preparation, and the QC measurement preparation. The front sides of the devices or the cabinets in the clinical laboratory 101 where the laboratory technicians work are indicated by triangle marks 118.
The management device 102 includes an input device 202, an output device 203, a communication device 204, an information processing device 205, and a storage device 213. The input device 202 is, for example, a pointing device such as a keyboard or a mouse, and is a device for inputting an instruction from a laboratory technician or an administrator. It is also possible to use a screen touch panel or the like as the output device 203. The output device 203 is a monitor or a printer that displays input information from the input device 202 and other result information. The communication device 204 is a communication device for the management device 102 to communicate with the position information acquisition device 224, the analysis devices/pre-processing device 103 to 108, and the terminal 225 via the networks, and a wired/wireless local area network, a wired/wireless global area network, a mobile phone line network, or a combination thereof can be used.
The information processing device 205 is a computer for executing various applications of the management device 102. The information processing device 205 includes a reagent replacement preparation timing detection unit 206 which is a logic for detecting a timing at which the reagent is to be replaced, a calibration preparation timing detection unit 207 which is a logic for detecting a timing at which the calibration preparation is to be started, a QC measurement preparation timing detection unit 208 which is a logic for detecting a timing at which the QC measurement preparation is to be started, a notification person-in-charge determination unit 209 which is a logic for determining a person in charge of task notification, a recommended replacement reagent determination unit 210 which is a logic for determining a recommended replacement reagent, a recommended calibrator determination unit 211 which is a logic for determining a recommended calibrator, and a recommended QC sample determination unit 212 which is a logic for determining a recommended QC sample. Details thereof will be described later.
The storage device 213 is a storage device that stores programs, data, and the like executed by the information processing device 205, and can use, for example, a non-volatile memory such as an EEPROM or a flash memory, an HDD, or an SSD. The storage device 213 is mounted on the analysis devices 103 to 107, and includes a reagent information management table 214 for managing information on reagents used for performing the clinical examination, a reagent replacement preparation time management table 215 for managing a time required for the reagent replacement preparation for each reagent, a calibration preparation time management table 216 for managing a time required for the calibration preparation for each reagent, a QC measurement preparation time management table 217 for managing a time required for the QC measurement preparation for each reagent, a person-in-charge schedule management table 218 for managing tasks of each laboratory technician, a person-in-charge position information management table 219 for managing position information on each laboratory technician in the clinical laboratory 101 acquired by the position information acquisition device 224, a reagent storage information management table 220 for managing stock information on the reagents, a calibrator storage information management table 221 for managing stock information on the calibrators, a QC sample storage information management table 222 for managing stock information on the QC samples, and a person-in-charge skill level management table 223 for managing a skill level of each laboratory technician. Details thereof will be described later.
When various applications of the management device 102 are implemented by executing programs by the information processing device 205, programs corresponding to the logics executed by the information processing device 205 are stored in the storage device 213, and functions of the detection units 206 to 208 or the determination units 209 to 212 are implemented by the information processing device 205 reading and executing the programs.
For example, the position information acquisition device 224 may grasp the position information by using the terminal 225 carried by the laboratory technician, or may grasp the position information on the laboratory technician by image analysis of a surveillance camera image installed in the clinical laboratory 101. For example, global positioning system (GPS), Beacon, ultra wide band (UWB), Wi-Fi positioning, sonic positioning, dead reckoning, indoor messaging system (IMES), or a combination thereof can be used.
The laboratory technician browses, by using the terminal 225, the notification sent from the management device 102, responds to processing, and responds to completion of the processing. An input device 226, an output device 227, and a communication device 228 in the terminal 225 have the same functions as those of the management device 102. A notification response device 229 has a function of responding to the notification from the management device 102. The terminal 225 is preferably a mobile terminal or a wearable terminal carried by the laboratory technician, and a notebook or desktop PC or the like may be used.
Column 302 is a mounted reagent management number, and is a number for identifying a reagent mounted on the analysis device. Column 303 is a reagent name. Column 304 is a reagent lot No. (reagent lot number), and the reagent lot No. is given when the reagent is manufactured by a reagent manufacturer. At the time of the reagent replacement, when the reagents before and after the replacement have the same reagent lot No., a calibration result can be taken over. That is, when the reagent to be replaced has the same reagent lot No., it is not necessary to perform the calibration at the time of the reagent replacement. Column 305 is a reagent mounting device position, and represents a position of the device on which the reagent is mounted. In this example, identification numbers defined in a clinical laboratory map to be described later are displayed. Column 306 is an expiration date of the reagent. A reagent that has passed the expiration date needs to be replaced. Column 307 is a remaining amount of the reagent. The analysis device may measure the remaining amount or may calculate the remaining amount based on the number of clinical examinations in the analysis device. Column 308 is the number of time of remaining measurement of the reagent, and can be calculated based on the remaining amount of the reagent in column 307. Column 309 is a reagent out prediction time point, and stores a time point predicted as a reagent out timing. The reagent out prediction time point can be predicted from the remaining amount of the reagent and an analysis frequency of the analysis device on the current day. For example, the number of time of remaining measurement in column 308 can be calculated by dividing the amount of reagent used per measurement from the remaining amount of reagent in column 307, and a reagent out time point in column 309 can be predicted from the analysis frequency of the analysis device on the current day. In the prediction of the reagent out time point, prediction quality is lowered when the remaining amount of the reagent is sufficient, and therefore, when the number of time of remaining measurement of the reagent exceeds 10, the reagent out prediction time point in column 309 is set to NULL.
Column 310 is a reagent replacement preparation start notification flag, in which zero is registered as an initial value, and the value becomes 1 at a timing when the reagent replacement preparation is to be started. Column 311 is a calibration preparation start notification flag, in which zero is registered as an initial value, and the value is set to 1 at a timing at which the calibration preparation is to be started. Column 312 is a QC measurement preparation start notification flag, in which zero is registered as an initial value, and the value becomes 1 at a timing when the QC measurement preparation is to be started. Hereinafter, a logic for setting these flags to 1 will be described. These flags are updated by the reagent replacement preparation timing detection unit 206, the calibration preparation timing detection unit 207, and the QC measurement preparation timing detection unit 208, respectively.
As will be described later, the reagent replacement preparation, the calibration preparation, and the QC measurement preparation are notified, and when the laboratory technician responds an intention to process, each is registered as a new task in the person-in-charge schedule management table 218. The work difficulty registered in the reagent replacement preparation time management table 215, the calibration preparation time management table 216, and the QC measurement preparation time management table 217 is registered as the work difficulty at this time.
In the clinical laboratory map 901, the clinical laboratory is divided into blocks, and the identification number is defined by an X coordinate and a Y coordinate of the block. The X coordinate is defined by integers from 1 to 11 in order from a left side to a right side, and the Y coordinate is defined by letters from A to E from the top to the bottom. For example, the position of the laboratory technician 917 is represented as 9E since the X coordinate is 9 and the Y coordinate is E. As described above, the shaded blocks in the clinical laboratory map 901 are blocks in which the devices/cabinets/work table are disposed, and thus the laboratory technicians cannot move on the shaded blocks. Triangular marks 918 represent front sides of the devices or the cabinets, and when the laboratory technician moves to the device or the cabinet for working, the laboratory technician moves to a block having the triangular mark 918. For example, when the laboratory technician 916 moves to the pre-processing device 908, a path order is 4C, 4D, 4E, 3E, 2E, 1E, 1D, and 1C, and a distance at that time is 7 because movement of the laboratory technician is 7 blocks.
On the other hand, with respect to a management device or work table for which the front side 918 is not designated, calculation is performed assuming that the laboratory technician moves to the corresponding block. When a plurality of shaded blocks are connected, the calculation is performed assuming movement to a position of a block at which the numerical value of the X coordinate is the smallest and the letter of the Y coordinate is closest to A.
The flag confirmation 1303 is processing of confirming whether the management device 102 needs any one of the reagent replacement preparation notification, the calibration preparation notification, and the QC measurement preparation notification. Therefore, the management device 102 confirms the reagent replacement preparation start notification flag (column 310), the calibration preparation start notification flag (column 311), and the QC measurement preparation start notification flag (column 312) in the reagent information management table 214.
When the reagent replacement preparation start notification flag (column 310) is 1 representing that the reagent replacement preparation notification is necessary, processing of person-in-charge schedule score calculation 1304 is executed. On the other hand, when the reagent replacement preparation start notification flag (column 310) is 0 representing that the reagent replacement preparation notification is unnecessary, if there is no other record in which the reagent replacement preparation start notification flag is 1, the processing proceeds to the end 1308.
The person-in-charge schedule score calculation 1304 refers to the person-in-charge schedule management table 218 (see
The person-in-charge position information score calculation 1305 calculates a person-in-charge position information score based on the position information on all the laboratory technicians currently in the clinical laboratory 101. The position information on the laboratory technicians is acquired from the position information acquisition device 224 as the identification number in the clinical laboratory map 901. Next, in the case of the reagent replacement preparation notification, the position information on the reagent cabinets 109 and 110 is acquired as a position information reference point. In the case of the calibration preparation notification, the position information on the calibrator cabinet 111 is acquired as a position information reference point, and in the case of the QC measurement preparation notification, the position information on the QC sample cabinet 112 is acquired as a position information reference point. In order to execute the task, the person in charge moves to the position information reference point and then moves to the analysis device or the work table, whereas the movement after the position information reference point is the same regardless of the person in charge. Therefore, in the person-in-charge position information score calculation 1305, the shortest distance until each laboratory technician reaches the position information reference point is calculated based on the acquired position information reference point and the position information on the laboratory technician. Specifically, the person-in-charge position information score is calculated as the shortest distance for reaching the front side 918 of the cabinet which is the position information reference point based on the clinical laboratory map 901. As a result, a person-in-charge position information score p for each laboratory technician is output. When there are a plurality of position information reference points, the shortest distance may be calculated for each of the plurality of position information reference points, and an average value thereof may be set as the person-in-charge position information score p.
Notification possible person-in-charge priority score calculation 1306 is processing of performing notification priority score calculation for determining a priority to be notified to the laboratory technicians in the clinical laboratory 101 by using the person-in-charge schedule score and the person-in-charge position information score calculated in the person-in-charge schedule score calculation 1304 and the person-in-charge position information score calculation 1305 as input. For example, a notification priority score Pr is given by the following (Formula 1).
Pr=m
1
·s+m
2
·p (Formula 1)
Here, m1 is a weight for the person-in-charge schedule score s represented by a positive constant, and m is a weight for the person-in-charge position information score p represented by a positive constant. The smaller the notification priority score Pr, the higher the priority, and the larger the notification priority score Pr, the lower the priority. As a result, the notification priority score Pr is output to all the laboratory technicians in the clinical laboratory 101.
Notification 1307 is processing of transmitting a notification to the terminal 225 carried by the laboratory technician having the highest priority based on a result in the notification possible person-in-charge priority score calculation 1306 and acquiring a response from the laboratory technician at a transmission target. When a response of not being able to be the person in charge is received from the laboratory technician, the laboratory technician is excluded until a certain period of time elapses, the person-in-charge schedule score calculation 1304, the person-in-charge position information score calculation 1305, and the notification possible person-in-charge priority score calculation 1306 are performed again, and a notification is transmitted to the next notification target until the person in charge is determined. When the response of not being able to be the person in charge is received from all the laboratory technicians in the clinical laboratory 101, a notification is transmitted to the administrator who collects the tasks of the laboratory technicians in the clinical laboratory 101.
A specific example of processing in the clinical laboratory according to the first embodiment will be described. Here, a case where a remaining amount of an AFP reagent is small in the analysis device 106 (reagent mounting device position 5D) and the reagent replacement is necessary will be described.
After the reagent replacement preparation timing detection unit 206 updates the reagent replacement preparation start notification flag, the notification person-in-charge determination unit 209 performs the processing of the flag confirmation 1303. The reagent information management table 214 at this time is shown in
Subsequently, the notification person-in-charge determination unit 209 performs the processing of the person-in-charge position information score calculation 1305. Locations of the laboratory technicians at this time are as shown in the clinical laboratory map 901 in
Subsequently, the notification person-in-charge determination unit 209 performs the notification possible person-in-charge priority score calculation 1306 to calculate the notification priority score Pr. At this time, if the notification priority score Pr is calculated using (Formula 1) in which the weight m1 is 1 and the weight m2 is 1, the notification priority scores Pr of the laboratory technicians 114 to 117 are 3.5 points, 5.5 points, 5.5 points, and 4.5 points, respectively.
As a result, the notification person-in-charge determination unit 209 transmits the reagent replacement preparation notification (see
The processing for the reagent replacement preparation notification is described above, and a flow of the processing is the same for the calibration preparation notification and the QC measurement preparation notification.
In a second embodiment, in addition to the first embodiment, the management device specifies and presents a recommended target (replacement reagent, calibrator, QC sample) at the time of a task request to a laboratory technician.
In the present embodiment, it is assumed stocks of the reagents, the calibrators, and the QC samples are stored in the reagent cabinets 109 and 110, the calibrator cabinet 111, and the QC sample cabinet 112, respectively. Stock information on the reagents, the calibrators, and the QC samples is managed by the management device 102. The stock information on the reagents, the calibrators, and the QC samples is registered by reading the information on a barcode, a two-dimensional barcode, or an RFID attached to each container thereof. Specifically, when a person in charge of purchasing stores the reagents, the calibrators, and the QC samples in the reagent cabinets 109 and 110, the calibrator cabinet 111, and the QC sample cabinet 112, such stock information is registered in the management device 102. Instead of the person in charge of purchasing, a laboratory technician working in the clinical laboratory 101 may be registered.
The stock information on the reagents, the calibrators, and the QC samples is managed by the reagent storage information management table 220, the calibrator storage information management table 221, and the QC sample storage information management table 222 (see
Processing 1803 is processing of lot No. score calculation, and is executed when the replacement target is a reagent. That is, when the lot Nos. are the same in the reagent replacement preparation notification, 1 is output as a lot No. score 1. On the other hand, at the time of the calibration preparation notification and the QC measurement preparation notification, 0 is always output as the lot No. score 1.
Processing 1804 is processing of expiration date score calculation, and is processing of determining whether a recommended target is superior depending on whether the expiration date is close. For example, a difference between a current date and a due date is output as an expiration date score d. For example, when the current date is 2019/09/24 and the due date is 2019/09/28, 5 is output as the expiration date score d.
Processing 1805 is recommended target score calculation, and is processing of calculating a priority as the recommended target based on a result of the lot No. score calculation in the processing 1803 and a result of the expiration date score calculation in the processing 1804. For example, a recommended target score Av is given by the following (Formula 2).
Av=m
3·1+m4·d (Formula 2)
Here, m3 is a weight with respect to the lot No. score 1 represented by a positive constant, and m4 is a weight with respect to the expiration date score d represented by a negative constant. The larger the recommended target score Av, the higher the priority, and the smaller the recommended score Av, the lower the priority. As a result, the recommended target score Av with respect to a total stock of the reagents, the calibrators, and the QC samples in the clinical laboratory 101 is output.
A specific example of processing in the clinical laboratory according to the second embodiment will be described. As in the first embodiment, a case where a remaining amount of an AFP reagent is small in the analysis device 106 (reagent mounting device position 5D) and the reagent replacement is necessary will be described.
After the reagent replacement preparation timing detection unit 206 updates the reagent replacement preparation start notification flag, the notification person-in-charge determination unit 209 performs the processing of the flag confirmation 1303. The processing of the flag confirmation 1303 is performed. From the reagent information management table 214 (see
The recommended replacement reagent determination unit 210 executes the recommended target determination logic 1801 for the stock of the AFP reagents which are the replacement target reagents. The reagent storage information management table 220 at this time is shown in
The lot No. score 1 is calculated for the AFP reagents whose storage reagent management numbers are 0002 and 0003 (lot No. score calculation 1803). Since the lot No. of the reagent requiring the replacement is “20190725-004” (see
Next, the expiration date score d is calculated for the AFP reagents whose storage reagent management numbers are 0002 and 0003 (expiration date score calculation 1804). When the current date is 2019/09/24, the expiration date score d of the storage reagent management number 002 is 9 and the expiration date score d of the storage reagent management number 003 is 8, based on each expiration date (see
Subsequently, the recommended replacement reagent determination unit 210 performs the recommended target score calculation 1805 to calculate the recommended target score Av. At this time, if the recommended target score Av is calculated using (Formula 2) in which the weight m3 is 3 and the weight m4 is −1, the recommended target scores Av of the AFP reagents whose storage reagent management numbers are 0002 and 0003 are −6 points and −8 points, respectively.
As a result, the storage reagent management number 0002 is specified as the recommended reagent and displayed on the reagent replacement preparation notification screen 1701 (see
Although the example in which the recommended replacement reagent is determined in the determination of the person in charge of the reagent replacement preparation is shown here, it is considered that the calibration preparation often precedes the reagent replacement preparation. Therefore, it is desirable to determine the recommended replacement reagent in the determination of the person in charge of the calibration preparation. At this time, when the reagents having the same lot No. are specified as the replacement targets, the notification of the calibration preparation is withheld. After that, upon receiving the completion of the reagent replacement of the reagents having the same lot No. as the replacement target, the calibration preparation start notification flag is updated to 0.
In a third embodiment, in addition to the first embodiment, the management device considers a skill level of a laboratory technician when determining an order of task requests to the laboratory technician.
For a laboratory technician who is unfamiliar with a work, such as a newcomer, a time required for reagent replacement, calibration preparation, and QC measurement preparation may be longer than a time required for a skilled laboratory technician. In the third embodiment, a priority of notification is set to be higher for a laboratory technician having a low skill level that requires time for the work. Accordingly, task allocation is executed earlier to a person in charge who may take time for processing, and influence of delay of the processing due to unfamiliarity of the laboratory technician can be reduced.
The management device 102 changes the predicted work average deviation time (column 1905) in the person-in-charge skill level management table 223 such that the person-in-charge skill level (column 1904) is brought close to 3 in an average case, brought close to 1 in a case where much time is required, and brought close to 5 in a case where no time is required, as compared with an average of the laboratory technicians working in the clinical laboratory. For example, assuming that the predicted work deviation time follows a normal distribution, the distribution is divided into 20%, 40%, 60%, 80%, and 100% from a lower side, the skill level of the laboratory technician distributed in 0% to 20% is changed to 1, the skill level of the laboratory technician distributed in 20% to 40% is changed to 2, the skill level of the laboratory technician distributed in 40% to 60% is changed to 3, the skill level of the laboratory technician distributed in 60% to 80% is changed to 4, and the skill level of the laboratory technician distributed in 80% to 100% is changed to 5.
The processing 2006 is processing of person-in-charge skill level score calculation. The management device 102 checks the person-in-charge attendance status (column 1903) in the person-in-charge skill level management table 223 (see
The processing 2007 is processing of performing notification priority score calculation for determining a priority to be notified to the laboratory technician in the clinical laboratory 101. For example, a notification priority score Pr is given by the following (Formula 3).
Pr=m
1
·s+m
2
·p+m
3
·k (Formula 3)
Here, m1 is a weight for the person-in-charge schedule score s represented by a positive constant, m2 is a weight for the person-in-charge position information score p represented by a positive constant, and m3 is a weight for the person-in-charge skill level score k represented by a negative constant. The smaller the notification priority score Pr, the higher the priority, and the larger the notification priority score Pr, the lower the priority. As a result, the notification priority score Pr is output to all the laboratory technicians in the clinical laboratory 101.
A specific example of processing in the clinical laboratory according to the third embodiment will be described. As in the first and second embodiments, a case where a remaining amount of an AFP reagent is small in the analysis device 106 (reagent mounting device position 5D) and the reagent replacement is necessary will be described.
After the reagent replacement preparation timing detection unit 206 updates the reagent replacement preparation start notification flag, the notification person-in-charge determination unit 209 performs the processing of the flag confirmation 1303. From the reagent information management table 214 (see
The notification person-in-charge determination unit 209 first performs the processing of person-in-charge schedule score calculation 2004. Since the details are the same as those of the first embodiment, the description thereof will be omitted, and the person-in-charge schedule score s of the laboratory technicians 114 to 117 are 1 point, 5 points, 2 points, and 1 point, respectively.
Subsequently, the processing of the person-in-charge position information score calculation 2005 is performed. Since the details are the same as those of the first embodiment, the person-in-charge position information scores p of the laboratory technicians 114 to 117 are 2.5 points, 0.5 points, 3.5 points, and 3.5 points, respectively. When the recommended target is specified as in the second embodiment, since the position information reference point is uniquely specified, the value of the score p is different from the above.
Next, the notification person-in-charge determination unit 209 performs the processing of the person-in-charge skill level score calculation 2006. The person-in-charge skill level management table 223 at this time is shown in
Subsequently, the notification person-in-charge determination unit 209 performs the notification possible person-in-charge priority score calculation 2007 to calculate the notification priority score Pr. At this time, if the notification priority score Pr is calculated using (Formula 3) in which the weight m1 is 1, the weight m2 is 1, and the weight ma is −1, the notification priority scores Pr of the laboratory technicians 114 to 117 are 0.5 points, 3.5 points, 1.5 points, and 3.5 points, respectively.
As a result, the management device 102 transmits the reagent replacement preparation notification (see
