Delivering patient safety and quality of care has become an increasingly technology-reliant process for healthcare providers.
Besides Electronic Medical Records (EMRs), automated administration systems, hospitals are turning to automatic identification technology such as RFID to track assets, medical devices, and surgical instruments.
Tracking for Operational Efficiency
Automating hospital equipment tracking helps improve efficiency and save costs for hospitals, which are tasked with managing hundreds of pieces of equipment across large facilities. Nurses may waste precious minutes searching for a wheelchair or IV pump. Surgeries may be delayed because a critical piece of equipment can't be found. Automated tracking saves time and helps organizations avoid unnecessary purchases to replace hard-to-locate equipment.
But this type of tracking also improves patient safety. Because of human error, it can be difficult to accurately account for all of the required surgical instruments before, during, and after a procedure. Accuracy can also be compromised by incorrect instrument lists, untrained personnel, or time constraints. Hand counting these instruments can affect the turn-over time for the operating room, and compromise the quality of care.
Tracking for Accreditation and Compliance
Accurate medical device tracking also plays a role in accreditation and compliance with government regulations. For instance, in an effort to improve patient safety, the Joint Commission (JCAHO) developed the Universal Protocol to avoid wrong-site, wrong-procedure, and wrong-person surgery errors. Part of the protocol includes verifying the items and surgical sets required for the procedure using a standardized list.
Those items should be checked before and after the procedure to ensure that everything necessary is already in the operating room before the procedure starts, and to make sure that no surgical instrumentation is lost or left inside the patient after surgery. To prevent these types of errors, all surgical items are recounted and inventoried after a procedure. If an item is missing, nurses must locate it before the procedure can be completed, at a cost of hundreds of dollars per minute of clinical time.
Tracking Medical Devices
In the case of medical device manufacturers, automatic identification technology can help meet the U.S. FDA's Unique Device Identification (UDI) tracking requirements in a matter of seconds. The UDI program was developed to provide more accurate tracking of medical devices in the healthcare industry in order to speed product recalls and improve patient safety. Starting in 2014, different classes of medical devices are required to include a permanent mark containing a unique identifier and manufacturing information. The number of devices that fall under UDI will be expanded each year through the 2020s.
Information on device labels will be centrally managed via the Global Unique Device Identification Database (GUDID), making it available to stakeholders across the healthcare supply chain. In addition to improving safety, UDI can help manufacturers better manage and track inventory. Healthcare organizations such as hospitals could also use the UDI to manage inventory or to track devices internally.
The UDI identification and information are encoded on the device using barcodes, direct part marking, or via RFID tagging. RFID tags are wireless, contactless, and long-range, making them particularly well suited for the automation of aspects of the Joint Commission's Universal Protocol, as well as meeting FDA UDI requirements. They are designed to withstand the rigors of the healthcare environment, as well as harsh sterilization processes.
Medical device manufacturers use RFID tags to identify each device uniquely. More importantly, RFID does not require line-of-sight scanning (like barcode labels or direct marks would), so items can easily be scanned even when the UDI tag or label is not visible. The information collected can be shared with other stakeholders in the lifecycle and workflow of medical devices.
Starting a Surgical Tracking System
RFID systems have been specifically designed to solve instrument tracking and identification challenges and help healthcare organizations achieve automated, accurate surgical counts and billing for surgical services, as well as complete inventory tracking of instrumentation. They are interoperable with an institution's existing systems and meet UDI requirements.
The core of a surgical instrument tracking system lies in the unique RFID tagging of instrumentation, trays, containers, and other devices. The Xerafy RFID tags used for the application are unique for their ability to withstand the decontamination and sterilization processes with no damage to the RFID tag. An easy-to-use handheld scanner is utilized to identify and view the instruments individually or in groups (sets/trays) within seconds on a screen rather than only by an individual’s visual assessment. After scanning, the user can find additional information for each instrument in the operating room, decontamination area, central sterile supply, or throughout the facility as needed by multiple departments. For customers that are already utilizing a 2D scanner system, the company offers an RFID scanner with a 2D bar code scanning option to list the items on the screen in the same way, making the transition to RFID very easy and simple.
The implementation of a surgical tracking system begins with the attachment of an RFID tag to each item. This is accomplished using an FDA-compliant method that does not compromise the function of the device. As each item is tagged and counted, a master list called the repository is created. Instrument lists for sets/trays are built from the repository. Instruments can be grouped together or listed separately with the required level of specificity. For example, the instrument list requirement for compliance with the Joint Commission can be fulfilled by including the correct number and generic type of instruments, rather than the specific instrument(s).
Tracking in SPD/CSSD and OR
Prior to sterilization, a nurse scans the instruments within a set/tray to confirm 100 percent accuracy of the list and actual instrument match. Any instruments not present would be highlighted in red on the screen of the handheld reader until the discrepancy is corrected.
Once instrument trays/sets are built and sterilized, a scanner is used by OR nurses to complete required counts instead of requiring the staff to visually match instruments against a list.
Scanning over the instruments provides a visual count on the screen as well as documentation of the time and place of the count. Again, missing instruments would be highlighted in red. The count is verified as complete or incomplete in seconds instead of minutes. Completing rapid, correct, and well-documented surgical counts provides immeasurable patient safety improvements, as well as cost savings related to turnover time. Another component of the system allows non-scannable items to also be tracked in the OR suite for preference list building, counting, re-stocking of supplies, pricing, and billing purposes.
Post-procedure, an institution may also choose to account for instruments at various stages of decontamination and set assembly prior to re-sterilization by scanning. Utilizing this feature may further assist with loss prevention cost savings. The system can also provide staff with the ability to immediately locate instruments within a facility. A further consideration for implementation is the capability of tracking the life cycle of an instrument. This feature includes tracking when an instrument is sent for repair or when sets/trays are loaned out. Additionally, when instruments are retired, all information necessary for replacement is readily available.
By utilizing RFID tags and surgical tracking management solutions designed for the healthcare environment, institutions can automatically track critical equipment, ensure the correct sets are available for each procedure within seconds instead of hours and improve patient safety and outcomes. Medical device manufacturers can also meet the requirements of the FDA UDI program via RFID, in addition to providing a means to enable additional tracking applications up and down the supply chain — including within the hospital.
