Based on the success of its bar code identification system for prescription drugs, the FDA is developing a protocol for tracking and identifying medical devices, which is designed to reduce medical errors, facilitate device recalls, improve adverse event reporting, and help spot incompatibility between devices. The FDA has gathered preliminary information from device manufacturers, hospital associations, and federal health agencies. The unique identification (UDI) system likely could include the manufacturer's name and device specific information (including make, model, lot and serial numbers, size, and software version). The FDA hopes to begin drawing up specific recommendations for a UDI system in the next few months.
