RFID Improves Tracking of Tissue and Medical Devices

Since Champion Medical Technologies added an RFID feature to its UDITracker solution, hospitals using the solution have reported that the technology has helped reduce the loss of high-value products.

Champion Medical Technologies provides hospitals with software for tracking tissue and implantable medical devices. Since the company released an RFID version of its software in late 2012, approximately 15 percent of its clients have transitioned to that product, enabling them to know where their high-value supplies and devices for surgeries and implantations are located. The RFID storage solution differs from Champion's conventional UDITracker by incorporating RFID technology into cabinets to automate the collection of location data.

Of the company's approximately 300 clients employing its UDITracker software platform for managing data about the receipt and use of implantable devices and tissues, 40 to 50 are now using RFID. About a quarter of those companies are currently in the process of adding RFID cabinets to their existing solutions, says Peter Casady, Champion Medical Technologies' CEO.

Terso's RFID-enabled cabinet
The typical client orders a single RFID-enabled freezer for storing tissues and two RFID-enabled cabinets for storing medical devices. Champion Medical's RFID-enabled cabinets, refrigerators and freezers are provided by Terso Solutions. The entire solution consists of the RFID-enabled cabinets, refrigerators and freezers, tags for products stored within them, and the UDITracker software to manage data about each item. That information can include expirations dates, serial numbers and any manufacturing information, such as the location and date of manufacture. The software can then provide users with information about what is in each cabinet, what has been removed, by whom, when this occurred, and what might need to be reordered, or may be about to expire.

Hospitals keep a certain percentage of tissues and implantable devices onsite for surgeries. Regulatory requirements are in place regarding how these items are stored, how quickly they are used and, in the case of tissues, how long they might have been exposed to room temperatures. The Joint Commission requires that hospitals maintain records for a minimum of 10 years and be able to provide those records when requested by regulators.

With the UDITracker RFID storage solution, all of this is accomplished through the use of RFID and bar codes. When an implant arrives at the hospital, a bar code on the packaging is scanned in order to enter device information, supplied by the manufacturer, into the UDITracker software. Champion provides a spool of Avery Dennison AD-317 RAIN UHF RFID tags, and users peel a sticker off the spool and attach it to that package, while also scanning the bar code on that tag in order to link it to the product in the software.

When the item is placed in a refrigerator, freezer or cabinet, an Impinj Speedway RFID reader and antennas built into the unit capture the tag ID number and store it in the software. Every time the container door is closed, it triggers the Speedway reader to capture the ID number of each UHF tag within, and forwards that data to the software via a cabled connection. That information is then compared against the previous reading event, in order to identify what has been added or removed from that container.
