Unique Device Identifiers: Improving Patient Outcomes and Care
Medical device failures can be debilitating and life-threatening for patients, especially when faulty technologies are not quickly identified and removed from the market. A new system developed by the Food and Drug Administration, or FDA, will help patients, clinicians, and hospitals spot problems more readily and make real- time assessments on the performance of devices used in patient care.
The unique device identifier
- The unique device identifier, or UDI, is a unique code consisting of two parts: one refers to the manufacturer and model of a device, and the other identifies additional information such as lot number and expiration date.1
- Devices classified by FDA at the highest risk level (Class III) will have UDIs by the end of 2014, and all devices will receive an identifier by 2018.
- Manufacturers will input the UDI and device information into FDA’s publicly accessible catalogue of devices— the Global Unique Device Identifier Database, or GUDID—so patients and physicians can learn more about specific products.
Supply Chain Management
Hospitals, manufacturers, and distributors can achieve supply chain efficiencies by utilizing the UDI as a uniform, national identifier to track products in procurement and inventory management systems. The UDI will provide notifications of product expiration dates, limit excess product stock, and reduce the time providers need to manage inventory to increase their availability for patient care.2
In more than half of the highest-risk recalls of devices, manufacturers were unable to locate all of the products in question and were therefore unable to correct or remove all problematic items.3 Incorporating UDI into supply chain systems and electronic health records, or EHRs, will enable hospitals to track and find recalled devices in their inventory and to identify and notify affected patients.
Patients, physicians, health plans, and FDA often lack information on long-term patient outcomes associated with approved medical devices. Integrating UDI into electronic health records, adverse event reports, registries, and insurance claims would allow health plans and FDA to understand how the device performs in large numbers of patients over long periods of time.4
