RFID Automates Witness Program for Narcotics Disposal

Intelliguard's Waste Witness software and anesthesia station enable hospitals to capture an automatic record of when narcotics were used on a patient, by which health-care provider and, if a drug was discarded, who witnessed that event.

Hospitals buy the cabinets outright and can use IntelliGuard's cloud-based software via a software-as-service (SaaS) model. As hospital personnel place medications within the cabinet, IntelliGuard's UHF reader and antenna array, built into the cabinet, capture the unique ID numbers and forward that information to the software, where it is linked to each medication's data. That information is then available on a dashboard to hospital management, pharmacists and anesthesiologists.

To access the cabinet, an anesthesiologist uses a touch screen key pad, a fingerprint reader and a contactless ID badge. "The provider logs in through a simple process," Claudepierre states. The hospital can assign access requirements for system users, depending on the security requirements and authorization protocols in place. If the software confirms that a specific user is authorized, the station's drawer will unlock. The worker can then open the cabinet drawer, remove the tagged medication and close the drawer.

Anesthesiologists typically remove multiple medications for a particular patient's procedure. Therefore, the cabinet captures the IDs of any drugs that are removed. An employee can return any unopened containers, at which time their tag IDs will be read once more, and each drug's status is thus updated in the software as being ready for use.

However, if a container has been opened but not completely administered, it needs to be discarded. The cabinet features a touch-screen function that allows that process. Before an individual can discard a medication, he or she requires a witness to provide a digital signature on the touch screen, thereby creating a record of what occurred. The user places the drug on the tray on top of the cabinet and selects the "Waste Witness" option on the touchscreen. The witness then uses his or her own ID badge or PIN to indicate that he or she has witnessed the disposal, and to officially sign the digital document of that event.

All of the station's data is forwarded to IntelliGuard's enterprise software, which identifies what has been removed and by which practitioner. The hospital can then view the cabinet's contents in real time via a dashboard, in order to confirm which products are available in each operating room, as well as when a given product needs to be restocked, or if an expiration date is imminent.

IntelliGuard manufactures the cabinets, including the RFID reader and antenna hardware, at the company's Carlsbad facility. Its customers most often apply off-the-shelf RFID tags to the medications as they receive them, then go through the encoding process. But in the future, Claudepierre says, the firm expects many products to arrive at the hospital already tagged, as pharmaceutical companies are either compelled to tag goods for customers or find value in the technology themselves for the purpose of supply chain management.

The cabinet can also be used for historical analytics. For instance, if a hospital wants to view trends, such as which medications are being used, as well as how often and when, it can analyze the data from the cabinet. "There are a couple of problems that we solve when it comes to inventory management" Claudepierre states, "but the primary benefits to the hospital or pharmacy are safety and security." IntelliGuard's station is now being validated for use with saline products, she adds, or for tracking other bags of liquids used in the health-care environment.
