Pharmaceutical RFID

The Future of RFID for the Pharmaceutical RFID Supply Chain: According to many of its proponents, RFID promises to save billions and radically change the way the supply chain works. For those in the pharmaceutical and health care industries, the anticipated benefits from implementing RFID go beyond just more efficient supply chains.

Efficiency: The primary reason that Wal-Mart and other major firms are interested in RFID is that they believe it can save them money by making their distribution operations more efficient. These companies already employ sophisticated systems that utilize bar codes. They require their suppliers to apply bar coded labels on shipments and transmit Advance Shipping Notices (ASNs) so that they can streamline their receiving operations. Even though they effectively utilize bar codes, these organizations believe that RFID can allow them to make their distribution operations more efficient. A typical pharmaceutical warehouse receives pallet loads of expensive products and quickly ships cases and eaches in Pharmaceutical RFID.

In addition, the organization needs to be able to track product down to the lot or even unit level after it is shipped. This has traditionally been accomplished using bar code labels, tying cases to pallets and eaches to cases, and a large amount of bar code scanning and manual data recording. RFID will permit the receipt of product by case or unit and will provide automatic tracking of the products throughout the supply chain. This has the potential of greatly reducing both direct and indirect labor.

Accuracy: The high cost of pharmaceutical products and the need to track material by lot or unit make tracking particularly important for the pharmaceutical industry using Pharmaceutical RFID. Using current technology and methods tracking is an expensive and time-consuming part of a Pharmaceutical RFID operation. Pharmaceutical RFID can provide an inventory tracking mechanism that is not dependent on human initiated scans. Transactions can be automatically recorded as product is moved within the warehouse.

Given enough tags and readers, RFID can provide the ability to track all inventory movements within a distribution center. All physical moves could be systematically tracked without the need for an operator to record the transactions in the system. Mis-picks and erroneous putaways where the wrong bar code is confirmed could be eliminated. Cost and technological barriers currently make this level of tracking impractical for most operations, but it is a theoretical possibility that could become a reality sometime in the near future.

Visibility: The pharmaceutical industry has been a leader in creating visibility throughout the supply chain using Pharmaceutical RFID systems. While traditional EDI provides a mechanism to share information between trading partners, RFID and the Electronic Product Code (EPC) Network will provide the basis for tighter and less costly collaboration and greater visibility within the entire supply chain. An EPC Network is designed to share information over the Internet. Conceptually, it allows one organization to locate and retrieve detailed product information stored on servers maintained by another firm for any given EPC. The ONS, or object name service, provides the appropriate network address or URL for where the information is stored. PML, or physical mark-up language, provides the means for the requesting application to retrieve the information.

The EPC Network establishes a vision for RFID that goes well beyond traditional automatic identification technologies. It provides the structure to track product movement throughout the supply chain. Properly maintained and updated PML servers can provide complete item-level history from the manufacturer to the end-user. This feature will make it possible to instantly know the history and location of every item in the supply chain. Today, independent systems often report this information only in financial transactions between partners and at best, send ASNs to the next trading partner. RFID provides the ability to have all systems use and leverage a single tag that creates visibility up the chain, improving the ability to plan for future events. Once the systems are in place, there is great potential to remove billions of dollars of inventory from the supply chain, passing savings along to all trading partners and end-users.

For the pharmaceutical and health care industry, lot and unit tracking are part of traditional regulatory and compliance standards. Traceability of Pharmaceutical RFID features are an excellent example of how this extended visibility will benefit the overall supply chain. Consider the process that a pharmaceutical or diagnostic manufacturer must go through to recall a specific SKU / lot. Existing supply chain systems only identify the immediate recipient of the lot. This recipient could be a wholesaler, hospital/clinic, drug store, or retailer who in turn distributes the product to other entities in the supply chain.

An individual item could go through many intermediate destinations before ending up in the hands of the final customer. Using Pharmaceutical RFID system allows for traceability at each point to track where the drug was distributed and by whom. At the lowest reasonable point, pharmacies could track what prescriptions were filled with what lot and greatly improve recall accuracy while minimizing costs. In addition, this concept could also be used to support pedigree paper regulations that require drug wholesalers to provide a record of each entity in the supply chain that has handled the controlled item being resold.

Security and Product Authentication using Pharmaceutical RFID technology: Probably no products have higher security requirements than those in the pharmaceutical industry. Products are extremely high in value, chemical analysis is required to determine if a product is counterfeit, and many products have elicit uses and thus, high street value. There is an ongoing problem of product diversion as well as the reintroduction of expired products into the supply chain.

Because Pharmaceutical RFID can passively track the movement of an individual object, it can be used in a similar manner as sensormatic and other loss-prevention technology to help reduce theft. Product authentication is another area that may prompt enterprises to turn to RFID for greater security. If every object has a unique identifier and detailed information on the object is stored in a PML server, any purchaser can validate the object's authenticity by interrogating its RFID tag. The information contained in the RFID tag could be encrypted so that counterfeiting will become nearly impossible. This would provide pharmaceutical manufacturers a powerful tool to combat product counterfeiting and product diversion and end users/customers will be able to ensure product integrity from the manufacturers.

RFID Drivers for the Pharmaceutical Industry: Pharmaceutical RFID presents the potential to provide tremendous benefits to the pharmaceutical and health care industries. The technology's capability for individual unit tracking and overall visibility will greatly reduce product diversion, making this and counterfeiting difficult. Dispensing errors will also be decreased, thus increasing patient safety. If product diversion does occur at any point, ability of Pharmaceutical RFID to identify the security gap will allow focused efforts to prevent it in the future. By being able to track individual units, RFID tags will reduce dispensing errors thus increasing patient safety. The tracking enabled by RFID will greatly reduce product diversion, and the data coded in the RFID tag will make counterfeiting and product diversion nearly impossible.

Some of the key benefits projected with the use of Pharmaceutical RFID include:

–        The ability to identify drugs at the individual and container level.

–        Assurance that the ID on the bottle has not been forged or mislabeled.

–        The ability to track exported drugs being re-imported and resold in U.S. markets at lower costs.

–        Minimized line-of-sight requirements to read product information.

–        Remote tracking of product movement and location.

–        Increased potential for reducing clinical trial times by reducing errors and improving delivery accuracy.

The potential for improvements in tracking and visibility are crucial to the long-term supply chain success for both the pharmaceutical and medical product industries to ensure that consumers are protected, product integrity is maintained, and shrinkage is minimized to maximize revenue using Pharmaceutical RFID. In addition, full visibility of the supply chain inventory will reduce out-of-date stock and returns, further improving profitability.
