## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 14/498,915 filed on Sep. 26, 2014, which is a continuation of U.S. Pat. No. 8,844,803 issued on Sep. 30, 2014, both entitled “SYSTEM AND METHOD FOR MONITORING PROGRESS OF DELIVERY OF A PATIENT-SPECIFIC MEDICATION IN A HEALTHCARE FACILITY,” the disclosures of which are hereby incorporated by reference in its entirety for all purposes.


FIELD
The present disclosure generally relates to medication distribution, and, in particular, relates to systems and methods for monitoring progress of delivery of a patient-specific medication in a healthcare facility.
DESCRIPTION OF THE RELATED ART
In a healthcare facility, such as a hospital, a pharmacist or pharmacy department within the hospital can coordinate dispensing of medications prescribed to patients (patient-specific medications) within the hospital. In recent years, some hospitals have been assisted with drug distribution management by implementation of automatic dispensing machines (ADMs). ADMs have effectively created branches of the hospital pharmacy department at different nursing stations where the ADMs are located.
It has been reported that the implementation of ADMs have decreased the time to first doses of those medications available in the ADM. However, for those medications not dispensed by the ADM (e.g., medications stored in a locked cabinet or a refrigerator), significant time of a care provider (e.g., nurse) can be spent on attempting to locate a given dose of a patient-specific medication. For example, the non-ADM-dispensed medication may be delivered to a counter, a shelf, or a hanger (e.g., for an IV bag), and the care provider would be unable to track the delivery of the medication.
While some ADMs allow the care provider to track medications that are currently available at the ADM, they do not provide any indication of the progress of delivery of any medications that are currently not available at the ADM. Knowing where the medication is and/or when to expect the medication at the delivery location can enhance operational efficiencies of medication dispensing by allowing the care provider to quickly locate the patient-specific medication and/or more effectively manage his/her time.
SUMMARY
For some or all of the reasons listed above, there is a need for systems and methods that allow a care provider to monitor progress of delivery of a patient-specific medication in a healthcare facility, and to provide trackable locations of medications other than an ADM.
In certain aspects of the present disclosure, a system for monitoring progress of delivery of a medication prescribed to a patient is provided. The medication is to be delivered to a delivery location in a healthcare facility. The system can comprise a patient/medication identification (ID) device provided on a package containing the medication, the patient/medication ID device comprising medication/patient information indicative of the medication and the patient.

DETAILED DESCRIPTION
In the following detailed description, numerous specific details are set forth to provide a full understanding of the present disclosure. It will be apparent, however, to one ordinarily skilled in the art that embodiments of the present disclosure may be practiced without some of the specific details. In other instances, well-known structures and techniques have not been shown in detail so as not to obscure the disclosure.
FIG. 1 is a diagram depicting an exemplary system 100 for monitoring delivery of a patient-specific medication in a healthcare facility according to certain aspects of the present disclosure. For ease and clarity of illustration only, without any intent to limit the scope of the present disclosure any way, it is assumed that the patient-specific medication is an epidural anesthetics IV solution that can be used during a child delivery, for example.
The system 100 includes a pharmacy 1 having a medication storage area 10, a fill and/or preparation (fill/prep) area 20, and a delivery pickup area 30. The medication storage area 10 includes a plurality of medications and supplies including an anesthetic drug (e.g., bupivicanine or chloroprocaine) and an appropriate fluid for the anesthetic drug. The anesthetic drug and the fluid are taken from the medication storage area 10 to the prep/fill area 20 where they are mixed together to produce the epidural anesthetics IV solution. A patient/medication ID device 72, such as a barcode label or an RFID tag, is provided on (e.g., affixed to) a package 70 (e.g., IV bag) containing the IV solution at the prep/fill area 20. The patient/medication ID device 72 includes patient/medication ID information indicative of the medication and the patient to whom the medication is prescribed. The package 70 is then taken by a technician at the pharmacy 1 to the delivery pickup area 30 where it is loaded onto a delivery cart 90 for delivery to a scheduled delivery/drop location 60 (“Medication Storage #307”) by a delivery person 2.
In the illustrated embodiment, the prep/fill area 20 has a barcode reader 24 provided therein that the technician at the pharmacy 1 can use to read the patient/medication ID device 72 (a barcode label in the illustrated example) before the package 70 is taken to the delivery pickup area 30. The delivery pickup area 30 has a barcode reader 34 provided therein that the technician at the pharmacy 1 can use to read the patient/medication ID device 72 once the package 70 is taken to the delivery pickup area 30. The delivery cart 90 may also be provided with a location barcode label 92. The pharmacy 1 also includes a processor 40 (e.g., pharmacy server) that is configured to receive an order for the patient-specific medication from a doctor 3. The processor 40 is coupled to a medication database 45 that is configured to store a variety of information including order status information and delivery progress information to be discussed below.
Also depicted in FIG. 1 is an intermediate stop location 50 (“Operating Room 1 #305”), located between the pharmacy 1 and the delivery location 50, where the delivery cart 90 makes a temporary stop, e.g., for delivering another package containing a medication for another patient.
The delivery location 60 and/or the intermediate stop location 50 can include, for example, a cabinet or a refrigerator for storing a patient-specific medication before use. In the illustrated example, the intermediate stop location 50 and the delivery location 60 are provided with location barcode label 52 and location barcode label 62, respectively. Each of the location barcode labels 52, 62 includes a unique location ID information indicative of the respective location 50, 60 where the corresponding barcode label is provided. As described above, the package 70 (e.g., IV bag) containing the patient-specific medication (e.g., IV solution) is provided with a patient/medication identification (ID) device 72. In the illustrated example, the patient/medication ID device 72 is a barcode label that includes patient/medication information indicative of the patient (e.g., “Jane Smith”) and the medication (e.g., “bupivicanine IV solution”). The patient/medication information may also contain other drug or patient related information such as the patient's medical conditions (e.g., allergies), name of the drug (e.g., bupivicanine), the drug dosage, the drug concentration, the drug administration schedules, and the drug delivery rate.
Also depicted in the system 100 of FIG. 1 is a reader device 84 that is hand carried by the delivery person 2 and/or attached to the delivery cart 90 and is configured to read the patient/medication information from the patient/medication ID device 72 provided on the package 70. In the illustrated example, the reader device 84 is a barcode scanner. In those embodiments in which the barcode scanner 84 is hand carried by the delivery person 2, the scanner 84 is also configured to read the location ID information from the location barcode labels 52, 62, 92.
In the embodiments described above, the location ID devices 52, 62, 92 and/or the patient/medication ID device 72 are passive ID devices, meaning that certain action (e.g., scanning) has be taken by the participant (e.g., a pharmacy technician or the delivery person 2) to retrieve information therefrom. In other embodiments, the ID devices can be active ID devices, meaning that the information retrieval from the ID devices occur automatically without an action taken by the participant. In some embodiments, the active ID devices can actively transmit signals containing the relevant information to the reader device 72 through a wireless link. The wireless link can use use a variety of technologies including Bluetooth, ZigBee, wireless USB, and proprietary systems. In other embodiments, the active ID devices do not themselves transmit signals, but respond to query signals generated by a reader device (e.g., by altering impedance of an RF circuit therein) as the reader device passes by the ID devices in close proximity.
In the illustrated example, each time the barcode scanner 84 scans an ID device (e.g., patient/medication ID device or location ID device), the information read thereby is wirelessly transmitted over a mobile device link 101 to a wireless bridge 50 that receives the information. The bridge 50 is in data communication with the processor 40 via a hospital network 107.
The processor 40 is configured to receive medication/patient ID information and/or location ID information read by the barcode scanner 84, generate delivery progress information therefrom, and store the delivery progress information in the medication database 45. The delivery progress information can include, but is not limited to: the patient's name or ID; the medication name or ID, the scheduled delivery location 60, one or more read locations where the medication/patient ID information and/or the location ID information was read by the barcode scanner 84, time when the information was read, and the name or ID of the delivery person 2.
The system 100 further comprises tracking devices 120, 130 that allow a care provider 4 (e.g., a nurse assigned the task of administering the patient-specific medication to the patient) to monitor the progress of the delivery of the medication. Each of the tracking devices 120, 130 is configured to receive a tracking request by the care provider 4, access the medication database 45, either directly or via the processor 40, retrieve the delivery progress information stored in the database 45, and indicate a delivery progress of the medication to the care provider 4 based on the delivery progress information. In the illustrated example, the tracking device 120 is an ADM having a processor (not shown), a display 121, and a keyboard 123; and the tracking device 130 is a mobile communication device (e.g., a cell phone, personal digital assistant (PDA), or pager) having a processor (not shown), a display 131, and a keyboard 133. The delivery progress information can inform the care provider 4 of a last-known read location and time of the last reading. Based on such information, the care provider 4 can decide, e.g., whether to wait for the delivery at the delivery location 60, go to the delivery location later at an expected delivery time, or go to the last-known location to retrieve the medication from the cart 90.
FIGS. 2A and 2B show a flowchart (FIG. 2B continued from FIG. 2A) illustrating an exemplary process 200 for monitoring delivery of a patient-specific medication according to certain aspects of the present disclosure. For ease of illustration, without any intent to limit the scope of the present disclosure in any way, the process 200 will be described with reference to the system 100 of FIG. 1. A person skilled in the art shall appreciate that the process 200 can be implemented in a system that is different from the system 100 without departing from the scope of the present disclosure. As an initial matter, it is hereby assumed that all location ID devices (e.g., location barcode labels 52, 62, 92) are provided on respective locations/areas 50, 60, 90.
The process 200 begins at start state 201 and proceeds to operation 210 in which pharmacy 1 (e.g., by the processor 40 and/or a pharmacist) receives and processes a medication order from the doctor 3. The process 200 proceeds to decision state 220 in which it is determined (e.g., by the processor 40 and/or the pharmacist) whether there is a problem with the medication order. Non-limiting examples of such a problem can include: the pharmacy 1 currently being out of stock of the patient-specific medication or an ingredient (drug or fluid) needed for preparing the medication; and the medication or an aspect thereof (e.g., delivery dosage) not complying with an established rule for the medication and/or the patient.
If the answer to the determination at the decision state 220 is Yes (a problem encountered with the medication order), the process 200 proceeds to another decision state 225 where it is determined whether the problem has been resolved or reconciled. If the answer is No, the process 200 proceeds to operation 227 in which an order status information indicating the problem encountered with the medication order (e.g., “Out of Stock”) is generated, and the medication database 45 is updated accordingly, and the process 200 ends at end state 229.
On the other hand, if the answer to the determination at the decision state 220 or at the decision state 225 is No (no problem with the medication order or the problem has been resolved), the process 200 proceeds to operation 230 in which the pharmacy 1 prepares the patient-specific medication. In the assumed example of the IV solution, the preparation can include taking a drug (e.g., bupivicanine) and a fluid (e.g., a saline solution) from the medication storage area 10 to the prep/fill area 20, preparing an IV solution comprising the drug and the fluid, and filling a package (an IV bag) with the IV solution. After the preparing and filling, a patient/medication ID device (e.g., a barcode label 72) is provided on the package 70 at the prep/fill area 20.
The process 200 proceeds to operation 235 in which the patient/medication information in the barcode label 72 is read by the barcode scanner 24 at the pharmacy prep/fill area 20 and sent to the processor 40. The processor 40 generates delivery progress information from the patient/medication information received from the barcode scanner 24, and updates (e.g., stores) the medication database 45 with the delivery progress information. If the care provider 4 were to make a medication track request after this point (but before the package 70 is delivered to the delivery pickup area 30 (operation 240)), the tracking device 120, 130 would indicate the prep/fill area 20 as the last-known read location.
The process 200 proceeds to operation 240 in which the package 70 containing the patient-specific medication is moved to the deliver pickup area 30. At the delivery pickup area 30, the patient/medication information in the barcode label 72 is read by the barcode scanner 34 and sent to the processor 40. The processor 40 generates new delivery progress information from the patient/medication received from the barcode scanner 34, and updates (e.g., stores) the medication database 45 with the new delivery progress information. If the care provider 4 were to make a medication track request after this point (but before the package 70 is loaded onto the delivery cart 90 (operation 250)), the tracking device 120, 130 would indicate the delivery pickup area 30 as the last-known read location for the package 70. Additionally, an optional location barcode label may be provided in the delivery pickup area 30 that can be read by the barcode scanner 34 or an optional handheld barcode scanner located in the delivery pickup area 30 to furnish the location information of the package 70.
In certain embodiments, before the package 70 containing the patient-specific medication is moved to the delivery pick-up area 30, a pharmacist at a pharmacist location in the pharmacy 1 performs a check of the content of the package 70 to ensure that the package 70 contains the right medication.
The process 200 proceeds to operation 250 in which the package 70 containing the patient-specific medication is loaded onto the delivery cart 90 by, e.g., the delivery person 2. The patient/medication information in the barcode label 72 of the package 70 and the location ID information in the barcode label 92 are read by the barcode scanner 84 carried by the delivery person 2 and sent to the processor 40. The processor 40 generates new delivery progress information from the patient/medication received and the location ID information from the barcode scanner 84, and updates (e.g., stores) the medication database 45 with the new delivery progress information. If the care provider 4 were to make a medication track request after this point, the tracking device 120, 130 would indicate the delivery cart 90 as the last-known read location.
The process 200 proceeds to operation 260 in which the delivery cart 90 carrying the package 70 arrives at the intermediate stop location 50, e.g., for delivering another package containing another patient-specific medication for a different patient. In that case, other patient/medication information associated with the other patient-specific medication and the location information in the location barcode label 52 provided at the location 50 are read by the barcode scanner 84 and sent to the processor 40 to indicate the delivery of the other package at the intermediate stop location 50. The processor 40 generates delivery progress information for the other patient-specific medication from the other patient/medication information and the location information received from the barcode scanner 84, and updates (e.g., stores) the medication database 45 with the delivery progress information for the other patient-specific medication. In some embodiments, the system 1 can also track the location of the cart 90 containing the package 70 by using the delivery information for the other patient-specific medication even though the package 70 is not delivered to the intermediate stop location 50. By tracking the intermediate stop location(s) of the cart 90, the system 1 can provide more updated current location(s) of the patient-specific medication. For example, if the care provider 4 were to make a medication track request after this point (but before the cart 90 arrives at the delivery location 60 (operation 270)), the tracking device 120, 130 would indicate the intermediate stop location 50 as the last-known location of the cart 90 carrying the package 70 (and hence the patient-specific medication). However, the cart 90 is a mobile location. The scheduled delivery location 60 is considered a “stationary” location. Tracking items on a delivery cart is more readily achievable than once the items have been delivered to a stationary location using conventional technology. This may be due to the relative control that a caregiver has over items being transported though a hospital or other health care facility. By comparison, once the item is removed from the mobile cart and provided at a stationary location, there has not been a tracking of that item at that stationary location. There is no record therefore, of the item location once removed from the mobile cart. The embodiments of the present disclosure address such concerns regarding stationary locations.
The process 200 proceeds to operation 270 in which the delivery cart 90 carrying the package 70 arrives at the scheduled delivery location 60. At the delivery location 60, the patient/medication information in the barcode label 72 and the location information in the location barcode label 62 are read by the barcode scanner 84 and sent to the processor 40. The computer 40 generates new delivery progress information from the patient/medication and location information received from the barcode scanner 84, and updates (e.g., stores) the medication database 45 with the new delivery progress information. If the care provider 4 were to make a medication track request after this point, the tracking device 120, 130 would indicate the delivery location 60 as the last-known read location. The process 200 ends at state 299.
FIG. 3 is a flowchart illustrating an exemplary process 300 for monitoring delivery of a patient-specific medication from the perspective of a tracking device (e.g., 120, 130) according to certain aspects of the present disclosure. As with the process 200 of FIG. 2, for the ease of illustration, the process 300 will be described with reference to the system 100 of FIG. 1. A person skilled in the art shall appreciate that the process 300 can be implemented in a system that is different from the system 100 without departing from the scope of the present disclosure.
The process 300 begins at start state 301 and proceeds to operation 310 in which a tracking request for the patient-specific medication is received by the tracking device 120, 130 from the care provider 4. Assuming that the tracking device from which the tracking request is made is the ADM 120 shown in FIG. 1, the tracking request can be made by the care provider 4 entering request data, such as the patient's name and/or a medication order number, using the keyboard 123 of the ADM 120.
The process 300 proceeds to operation 320 in which, after receiving the tracking request, the tracking device 120, 130 accesses the medication database 45 and retrieves the delivery progress information stored therein. In certain embodiments, the database 45 is accessed directly by the tracking device 120, 130. In other embodiments, the database 45 is accessed via the processor 40. In some embodiments, the tracking device 120, 130 retrieves the order status information in addition to the delivery progress information. For example, when the tracking device 120, 130 determines that the delivery progress information indicates that the patient-specific medication has not been prepared and filled (e.g., by lack of an ID reading at the prep/fill area 20), the tracking device 120, 130 can retrieve the order status information also stored in the database 45 to determine whether there is any problem with the medication order.
The process 300 proceeds to operation 330 in which the tracking device 120, 130, upon retrieving the delivery progress information, determines, based the retrieved information, a delivery progress of the patient-specific medication. The delivery progress can include, but is not limited to, the last-known read location where the patient/medication ID device 72 and/or a location ID device 52, 62, 92 was read, time of the reading, and a delivery status (e.g., whether the patient-specific medication has been delivered to the scheduled delivery location 60).
The process 300 proceeds to operation 340 in which the delivery progress so determined is indicated to the care provider 4 who made the medication tracking request. In those embodiments in which the tracking device 120, 130 also retrieves the order status information from the medication database 45, a problem, if any, that was encountered with the medication order can also be indicated. In certain embodiments, the delivery progress and/or the order status can be displayed on the display 121, 131 of the respective tracking device 120, 130. In those embodiments in which delivery information associated with another package may be used for tracking the cart 90 as described above with respect to the operation 260, the last-known cart location may also be indicated. Examples of such a display of the delivery progress information are provided in FIGS. 4A and 4B. After completion of operation 340, the process 300 proceed to an end state 309.
For instance, FIG. 4A depicts an exemplary display 400A that provides a delivery progress indication in response to a tracking request made at a first time (11:03 am). The display 400A includes a header section 410A that indicates the patient (“Jane Smith”), the medication (“bupivicanine IV solution”), the delivery location (“Medication Storage (#307)”), the delivery person (“Kevin Doe”), the tracking request time (11:03 am), and the delivery status (“In-transit”). The display 400A also includes a read list 420A that indicates read locations where readings of the patient/medication ID and/or the location ID were made by the reader device 84, 24, 34, and times of the readings. The list 420A indicates that the last-known read location is Operating Room 1 (#305), corresponding to the intermediate stop location 50 (FIG. 1).
FIG. 4B depicts an exemplary display 400B that provides a delivery progress indication in response to a tracking request made at a second time (11:15 am). The display 400B includes header 410B and read list 420B. The header list 410B indicates that the latest tracking request was made at 11:15 am and that the delivery status is indicated as “Completed” reflecting the fact that the package 70 was delivered to the delivery location 60 at 11:10 am, as indicated in the read list 420B.
In some embodiments, in lieu of or in addition to presenting the read locations in such a text format as in FIGS. 4A and 4B, the read locations can be indicated (e.g., juxtaposed) on a map of the healthcare facility. FIG. 5 depicts an exemplary display 500 of a hospital map with read locations with corresponding read locations indicated thereon as of the first time (11:03 am).
In certain embodiments, the system 100 allows the care provider 4 to receive an electronic message when the package 70 is delivered to the delivery location 60. For example, the processor 40 can be configured to send, upon determining the delivery, a phone-, e-mail-, and/or pager-message to the mobile communication device 130 carried by the care provider 4. By way of example, a monitoring software running on the processor 40 can be programmed such that when the location ID information received from the reader device 84 indicates that the last-known read location corresponds to the scheduled delivery location 60, the software causes the processor 40 to automatically send an electronic message to the mobile communication device 130 via the network 107, an Internet, or a cellular network. In some embodiments, the processor 40 is configured to send an electronic notification when a medication order is not filled within a predetermined time (e.g., 2 hours) after the pharmacy 1 receives the order. Such automatic notification features further provide further operational efficiencies by eliminating the need for the care provider 4 to repeatedly check for the medication fill and/or delivery status.
In certain embodiments, various aspects of the present disclosure can be utilized to implement an inventory control system in an acute care facility that tracks a patient-specific medication through a supply chain (e.g., from a pharmacy to a delivery location). In such a system, information (e.g., medication/patient information and location IDs) can be collected from various locations in the acute care facility and stored in real time in a database with a web/agent front end. The web/agent can aggregate the information in context of a patient's needs. A caregiver (e.g., a nurse) in the acute care facility assigned to the patient can be automatically notified of an availability status of the patient-specific medication. For instance, the caregiver can receive a notification when the medication has become unavailable or about to be stocked out in the pharmacy or in a medication dispensing device (e.g., ADM). The caregiver can also be notified of a status of orders pertaining to the caregiver's patients such as when the orders are in queue, what the length of the queue is, and/or if the orders are cleared. The automatic notification can be received through cell phone text messaging, e-mail messages, or Windows live alerts, for example. Alternatively or additionally, a medication storage device (e.g., ADM) that is configured to store the patient-specific medication can receive and display an automatic notification such as what orders are ready in the queue or what items will be stocked and how soon. Through such automatic notification features, the caregiver can receive timely notification of medication availability in the context of the patient's need. An inventory control system with such features avoids the need for the caregiver to call a pharmacy to check the status of the medication and delays and inefficiencies associated with such checking.
It shall be appreciated that various embodiments of the present disclosure described above are exemplary only and many changes including additions, deletions, and modifications may be made to the embodiments without departing from the scope of the present disclosure. For example, all or some of the read locations 50, 60 and the cart 90 may be provided with respective barcode scanners that are attached to a fixed device (e.g., a computer or a storage cabinet) at the locations. In such embodiments, there is no need to provide for and scan the location barcodes 52, 62, 92 since the respective fixed barcode scanner would “know” where it is located. The patient/medication ID device 72 and/or the location ID devices 52, 62, 92 may be RFID tags instead of the barcode labels, and the reader device 24, 34, 84 may be an RFID reader. The medication database 45 comprising the delivery progress information may reside inside the processor 40 (e.g., pharmacy server). The delivery progress information may be stored in a database that is located outside the pharmacy 1. The package 70 may be hand-carried by the delivery person 4 to the delivery location 60 instead of being carried on the delivery cart 90. The delivery location 60 may be another ADM. The patient-specific medication may already be stored in a pre-labeled container in the pharmacy medication storage area 10 and may not need to be separately prepared and filled at the prep/fill area 20. There may be multiple intermediate stop locations or no intermediate stop location between the pharmacy 1 and the delivery location 60.
FIG. 6 is a schematic block diagram depicting a computing system 600 that may be employed as the processor 40 of FIG. 1. The computing system 600 may be a standard computer server connected to the hospital communication network 107 and located in the pharmacy 1 as shown in FIG. 1 or in a hospital data center or computer room outside the pharmacy 1, although other locations may be employed.

The memory 670 external to the processor 660 or alternatively, the memory 662 internal to the processor 660 may include such an medication database.
Certain aspects of delivery monitoring systems and methods described herein can be performed by the processor 660 executing one or more sequences of one or more instructions contained in an internal machine-readable medium such as the internal memory 662 or the memory 670. For example, the processor 660 can receive the patient/medication information and the location information from the reader device 24, 34, 84 via the network interface 690, generate the delivery progress information based on the received information, and store and retrieve the delivery progress information to and from the medication database 45.
The processor 660 may also send messages to the mobile communication device 130, such as cell phones, PDAs, and pagers, over a mobile device link 105 via the wireless network interface 692 to send an automatic electronic notification when the delivery is completed. The mobile device link 105 may include the hospital network 107 and internal or external wireless communication systems that are capable of sending messages that can be received by mobile device 130.
Such instructions and/or information may be read into the memory 662, 670 from another machine-readable medium, such as a CD, flash memory, or a wireless transmission. Execution of the sequences of instructions contained in the memory 662 causes the processor 660 perform the process steps described herein. One or more processors in a multi-processing arrangement may also be employed to execute the sequences of instructions contained in memory 662. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement various embodiments. Thus, embodiments are not limited to any specific combination of hardware circuitry and software.
The term “machine-readable medium” as used herein refers to any medium that participates in providing instructions to processor 660 for execution or storing results of or parameters (e.g., variables or constants) for computations such as for the determination of the last-known read locations and whether to send an automatic electronic notification. Such a medium may take many forms, including, but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as data storage device. Volatile media include dynamic memory, such as the memory 670.
