    What is RI Witness?

    RI Witness uses Radio Frequency Identification(RFID) to detect and monitor all activity in the IVF Laboratory.  The system helps mitigate the risk of human error every time samples are moved from one dish or tube to another, and safeguards every stop of the IVF cycle.

    Throughout the lab, RI Witness readers are situated wherever work is undertaken, critically where samples are handled. Embryology heated or unheated plates with in-built RFID readers can be integrated into  a worktop.

    They are active all day, every day, so a check cannot be overlooked.

    An RI Witness work area has a tablet computer connected to the server, integrated with your clinic’s patient database*.  Thanks to self-adhesive RFID tags attached to all the laboratory plasticware, it is possible to ensure protocols are followed and only compatible samples are worked on at any one time.

    The system is automatic, so it does not require additional steps by embryologists to identify samples, which are necessary with human double witnessing or barcode witnessing systems.

    By automatically tracking, monitoring and recording across all your work areas, RI Witness frees up your time, energy and expertise.

    This secured process fills everyone with total confidence2.

    *Subject to compatibility, some programming may be required

    Why Do I Need RI Witness?

    What if you had a mix-up?

    Many embryologists tell us this concerns them, and from time to time, the media reports an error which has wide-reaching effects; not only on the family but also the embryologists, the lab and the wider community’s perception of IVF practices. Primarily, RI Witness was designed to mitigate this risk. Through constant monitoring it reduces the chance of human error associated with repetitive tasks and misperception1,3.

    Compared to other witnessing protocols it involves less disruption and accelerates the speed of witnessing which can reduce the time an embryo is out of the incubator3.

    In response to ongoing customer feedback, RI Witness has been developed to include many time-saving features to make laboratory work easier. RI Witness does the work of many people, potentially freeing up staff members to carry out more procedures, increasing overall laboratory efficiency. It can also be used as a quality management tool ensuring consistent adoption of laboratory protocols and monitoring staff performance and simplifying audits.

    Using RI Witness, provides your clinic with a competitive advantage while offering a secure, patient-orientated service.

    “RI Witness has improved efficiency by streamlining our working practice – laboratory procedures are performed at the optimum time with a real-time witness.  

    The ease of operation is great and the system has proved to be a versatile audit tool.”

    Sophie Jewitt, Senior Clinical Embryologist
    Gateshead Fertility Unit, England

    How Does It Work?

    RFID versus Barcodes

    RI Witness uses RFID technology instead of barcodes to constantly safeguard the IVF process, from start to finish.  Only RI Witness can monitor every procedure with no workflow interruptions.

    Multiple Dishes

    RFID

    RI Witness reads all dishes simultaneously and automatically allowing the operator to work uninterrupted.

    Barcodes

    Barcodes need to read each each dish, lined up or individually in the line of sight for the scanner to verify that they are compatible.

    Samples will need to be taken out of the work area to be checked, which can be disruptive.

    Recording Activities

    RFID

    RI Witness monitors the work area under the microscope constantly. Giving 24/7 protection, a check cannot be unintentionally overlooked.

    Barcodes

    Barcodes security relies on the operator remembering to do checks.  In fact, a procedure can be performed without the activity being logged int he system, no alert or action will be instigated.  The IVF cycle’s security could be compromised.

    Mismatches

    RFID

    RI Witness will alert the operator immediately, before samples are manipulated, if incompatible samples are in the same work area. This allows corrective action to be taken while the security of the sample is intact.

    Barcodes

    Using a human or barcode witnessing system, two unrelated samples can be in the same work area, and may even be manipulated, without the operator being aware that the samples are incompatible.

    Perceptual blindness, tiredness, involuntary automaticity5, ambiguous accountability, conscious automaticity and interrupted workflow can all lead to potential mistakes.

    Safety of RFID and RI Witness

    We understand it is imperative the conditions in your laboratory are optimized for ART procedures.  There is no room for compromise. That is why we use technology that does not harm embryos or humans.

    Tested

    We asked an independant test centre, the University of Liège, Belgium, to devise a comprehensive experiment to prove out theories about the safe use of RFID with gametes and embryos.

    For the test they:

    • Increased the output power of the reader by 10x
    • Increased the time that the embryos were in the radio frequency field by 70 times what would be expected in an IVF cycle
    • In the experiment total exposure was 700x what would be expected in an IVF lab

    Results:

    • Normal development to mouse blastocyst compared to the control group
    • Normal live birth rate (LBR) compared to the control group
    • Normal fertility in the female pups with normal 2nd generation LBR

    RFID

    Every day, we are surrounded by radio frequency emissions from modern technology.

    The potential effects radio frequencies have on cells and tissues depend on the frequency and power density to which they are exposed.

    The facts:

    • RI Witness RFID tags do not emit or receive radio waves when they are not on a reader or in the incubator
    • The tags are passive, with no internal energy source, so they are only activated when in a 1-5cm range of an RI Witness reader
    • Embryos and gametes are only exposed to the radio frequency fields for short time periods

    Statistical Evidence

    A four-year statistical analysis in one clinic looked at more than 10,000 live birth, before and after the introduction of  RI Witness.  The analysis showed no changes to results in both live births and malformations over the two periods7.

    Certified

    Our embryology heated plates are CE marked as medical devices (GB98/13044) and FDA cleared.  They offer highly stable heating across the reader.

    Our tags and labels are batch tested to MEA >80% survival to blastocyst stage6.

    “Numerous patients have informed us that they feel better knowing that this safeguard, RI Witness, is in place.”

    Laboratory Director, Overlake Reproductive Health, USA

    A Proven and Validated System

    Thanks to widespread clinical use of our Electronic Witnessing System (EWS) for over 10 years, multiple posters and papers have been published that cover and discuss questions often raised about RI Witness.

    The Real Risk of Human Error

    What is the actual risk of mismatches, for labs relying on human double witnessing, without an electronic system to ensure the cycle is secure?

    Using RI Witness, several laboratories analysed data from witnessed steps to establish a “true rate of human error”. The studies found their mismatch rate was up to 0.11%1 of witnessed actions. A true mismatch involves mistaking an identity check, other errors, such as administration errors, were discounted.

    This is the first time true errors rates have been studied in an IVF laboratory1.

    Efficiency In The Lab

    How can RI Witness make my lab more efficient?

    Human double witnessing means a colleague must double check the identity of patient samples at critical points. This has been mandatory in the UK since 2004.

    Since then, extensive comparisons have been undertaken to compare human, barcode and the RI Witness RFID systems. The evidence concluded that RI Witness was faster, more efficient, and ensured samples were out of the incubator for less time overall4 when compared to human double witnessing.

    Staff and Patients’ Considerations

    Assessing how the implementation of an Electronic Witnessing System might affect your patients and embryologists is very important. Evidence shows they feel the benefits of using the system in a short space of time.

    Patient Reassurance

    How might my patients feel about the use of an electronic witnessing system?

    One study found that patients and embryology teams felt reassured when using RI Witness, and that it could be used as a trusted strategy to decrease patient stress concerning mismatches; 97.1% of patients confirmed they were more reassured if an Electronic Witnessing System was used in their clinic8.

    Key Staff Concerns

    Will the installation of an Electronic Witnessing System be disruptive?

    The installation of RI Witness and the staff training required takes less than a week to complete, under normal circumstances. A testing and validation phase of one month follows, after installation. A study conducted in an Italian clinic found system users were 96% satisfied with its performance immediately after validation3.

    Bespoke Protocol Management

    As part of the installations, a bespoke flow chart (Witness Point Diagram) is created with the assistance of a CooperSurgical installation specialist.

    It is designed by you and works in line with your existing Standard Operating Procedures (SOPs). Each critical step carried out by every operator, wherever they are in the laboratory, is logged in a manner compatible with your working practices.

    The Witness Point Diagram is then tested step by step.

    The easy-to-use software interface allow you to amend the diagram as your SOPs and needs evolve.

    You are in control, so there are no delays such as waiting for outside assistance.

    Whole Lab Integration

    Every process in every part of the lab is automatically detected, logged and protected.

    Before installation, together we create a plan that outlines your exact requirements including the mapping out of locations for readers and server connections.

    Integration

    We can fit embryology heated plates into all workstations from major suppliers; flush fitted integration is possible with K-Systems and ORIGIO cabinets.

    Work areas can be connected through Wi-Fi or LAN cables to a central server which means everything works together and data updates in real time.

    Our software works with leading patient management databases.

    We also work closely with clinics and their database administrators on an individual basis to ensure smooth integration with RI Witness.

    “The integration of RI Witness into our daily routine was fast and simple and allowed for an improvement in system usage after a short period of time”

    Dr Roberts Maggiulli, Biologist Laboratory Coordinator, Clinica Genera, Italy

    Additional Functionality

    Use RI Witness to its full potential*

    On top of the security advantages with RI Witness, the bespoke infrastructure can also be used to improve other aspects of your laboratory’s daily work load.

    *Some of these features require additional purchases

    Workflow Management Tool

    You can look at the activity being done in the lab, how long it takes, where it takes place and who performed it. This information may indicate that staff training is needed, that there are bottle necks in the process or that equipment requires upgrading or replacing. All of this data allows you to make informed decisions about laboratory work improvements.

    Procedure data can be explored in detail or summarized into pie or bar charts.

    Cryopreservation Tracking

    Patient samples can be tracked as they enter and leave cryo storage.

    The RI Witness RFID system converts data to cryo-suitable barcode identification labels. Durable, laboratory-proven Brady labels are used to identify the vials or vitrification straws.

    On thawing/warming, the barcode information is linked automatically with the embryo thaw dish.

    Paperless Data Capture

    You can enter data directly into patient records using small touch screen displays or a keyboard and mouse interface installed at your work areas.

    By inputting directly, transcription errors are minimized and multiple data handling is avoided.

    Data can be accessed and analyzed immediately.

    Daily Overview Board

    Using a Cycles Overview Display you can view active cycles in the lab.  or each cycle the last procedure and current status for the day is shown, for example, in progress, finished or not started.

    This information is displayed on a big screen fixed to the lab wall and can be accessed from any networked PC.

    The entire team gains an overview of the lab’s daily activities and how the day’s work is progressing.

    Materials Traceability

    You can record which products are used for each cycle type.

    Records can be sorted and filtered in various ways to cross-reference patient cycles and material batches.

    It allows you to keep a full record of consumables used in the laboratory, which is often a requirement of regulatory authorities.

    Imaging Function

    Capture images and videos from every microscope in the laboratory, at any stage of the patient cycle. Information and images for each patient’s cycle can be saved in the patient’s file and accessed immediately from any networked PC.

    Patient Display Screen

    Show the patient their embryo pre-transfer while checking it against their patient ID card in the transfer room. This enables the patient to be directly involved.

    Q: What is RFID? 
    A. RFID (Radio Frequency Identification) is a generic term for technologies that use radio waves to automatically identify objects. Labels with tiny microchips embedded in them are attached to all plasticware such culture dishes, test tubes and patient identity cards before being assigned to a patient. These microchips are read by the RI Witness readers. There is no need to directly scan the labels, the whole process is automatic and many tags can be read simultaneously.

    Q: How does the RFID label transmit the information? 
    A: RI Witness uses RFID tags and a reader. The reader sends out electromagnetic waves and the tag receives these waves. The RFID tag draws power from the field created by the reader and uses it to power the microchip’s circuits. The microchip then modulates the waves that the tag sends back to the reader and the reader converts the new waves into digital data.

    Q: Are there any health risks associated with RFID and radio waves?
    A: RI Witness uses a radio frequency similar to the signals received by your car radio. We have organised exhaustive independent Mouse Embryo Assay (MEA) studies to demonstrate that RI Witness RFID does not have any detrimental effect on the development of embryos. These tests used radio waves which are 700 times stronger than those used by the actual product.

    Q: Why is RFID better than using barcodes? 
    A: The most significant difference is that barcodes use line-of-sight technology. That is, a scanner has to “see” the barcode to read it, which means it is necessary to orientate the barcode towards a scanner for it to be read. Barcode systems therefore rely on the user remembering to confirm patients’ sperm, oocytes and embryos match. This can be prone to human error, and if not done correctly, can give a false record.

    RFID, by contrast, doesn’t require line-of-sight. Tags can be read as long as they are within range of a reader. In addition, multiple RFID tags can be read at the same time, meaning that several items can be identified together. RI Witness uses this ability to automatically check everything that is brought into the working area.

    RFID technology provides a level of security that can eliminate human identification errors. It monitors everything in every work area, every second of every day. It also offers an extremely large number of unique identities (UID). This means that each sample container can has its own UID and that procedures can be tracked in detail. The system knows exactly what has happened to the samples and which containers were used. The communication between tag and reader is very secure.
