Patient Reassurance

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

Patients can be reassured throughout their time at a clinic through accessible literature, up-to-date technology and a record of their cycle including images and videos captured from every microscope used.

Additionally, prior to transfer they can be shown their embryo, linked to their patient ID, demonstrating how seriously a clinic takes their security.

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.

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.

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.

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.

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.
