UDI Adoption

UDIs are unique identifiers for a medical device that are required on the device label and packaging of both human and machine-readable forms. These are required on the medical devices that are intended for more than one use and intended to be reprocessed before each use. The U.S. FDA mandated the UDI system in September 2013.

The BUILD Initiative (Building UDI into Longitudinal Data for Medical Device Evaluation) supports MDEpiNet by developing the infrastructure and methodology for robust post-market surveillance, research, and innovation through a system of automated capture of clinical data from EHRs and UDI associated device data, all of which are linked to national registries. The focus of the BUILD initiative is to:

  • Implement an UDI system at the point of clinical care and leverage UDI to connect data sources

  • Access the global unique device identification database)

  • Move information on devices to clinicians for patient care,

  • Allow researchers to assess device effectiveness and safety

  • Support device innovation across the device product life cycle

The BUILD Initiative has three complementary components:

  • Extension of the UDI Implementation Pilot: The Mercy Health coronary stent UDI demonstration project was extended to production status at two additional health systems, Geisinger and Intermountain Healthcare.

  • Medical Device Data Capture and Exchange: Leading Practices and Future Directions: Leadership interviews were performed in hospital systems that have implemented UDI for implantable devices to rigorously assess leading practices and gaps; a multi-stakeholder consortium of hospital system and manufacturer leaders in UDI was formed (BUILD Consortium); a BUILD website was created and maintained for education and information sharing.

  • Electrophysiology structured reporting Providing UDI for Leads and devices using industry Standards to EHRs and CVIS systems:The use and utility of UDI across multiple dimensions of health care (including patient engagement) will be demonstrated for cardiac implantable electronic devices (CIED) such as pacemakers, cardioverter defibrillators, and CIED leads.

Unique Device Identifier (UDI) Implementation in the Electronic Information of a Single Health System: An MDEpiNet Demonstration

Principal Investigator: Joseph P. Drozda, Jr., M.D.

Brief Description

The U.S. Food and Drug Administration (FDA) envisions strengthening the system of medical device postmarket surveillance through the use of electronic health information gathered in the course of care and sees unique device identifiers (UDIs) as keys enabling linking of disparate systems. To this end, the FDA supported a demonstration performed by Mercy Health (a 4-state regional health system headquartered in St. Louis, Missouri) that had 3 aims:

  • to implement a coronary stent surveillance system in its electronic health record (EHR),

  • to identify the obstacles for creating such a system along with potential solutions, and

  • to assess the usefulness of the EHR data in device safety surveillance.

Mercy designed and implemented a system for capturing prototype coronary stent UDIs by means of barcode scanning in its cardiac catheterization laboratories (cath labs) and incorporating them in its supply chain management, inventory management, billing, and cath lab clinical systems. The UDI was used to link the specific coronary stent with the patient in whom it was implanted. This resulted in creation of a database that included pertinent UDI-related device information and clinical data obtained from the EHR thus enabling assessment of coronary stent safety and effectiveness over time.

This “proof of concept” pilot demonstrated that EHR data can be useful in evaluating implanted medical devices in the postmarket setting. The next step would be to work with a national device registry to obtain this same information in de-identified format from multiple health systems in order to assess large numbers of devices nationally and create a clearer picture of device performance and safety in the real world.

Project Partners

Mercy is a member of the Healthcare Transformation Group (HTG)—an alliance of 5 large health systems that includes Geisinger, Intermountain Healthcare, Kaiser Permanente, and Mayo Clinic. HTG is advocating for supply chain standardization aimed at reducing costs while improving healthcare quality and safety and actively supported the Mercy UDI demonstration. In conjunction with its HTG partners, Mercy assembled an expert panel of interventional cardiologists to help in refining the project design and to select meaningful coronary stent attributes for inclusion in the surveillance database. The expert panel accomplished this task by working with a broader group of stakeholders that included representatives of HTG health systems, professional societies (American College of Cardiology and Society for Cardiovascular Angiography and Interventions), and industry (Abbott, Boston Scientific, and Medtronic) as well as FDA.

The Mercy team was multidisciplinary; it was led by a senior health services researcher, and was a combined effort of a number of departments: Cath Lab, research, information technology, supply chain, and operational optimization.

Sources of Funding

The UDI implementation pilot was a part of the MDEpiNet Methodology Center of Harvard Medical School. This work was supported by contract DHHS/FDA-22320172C from the Center for Devices and Radiological Health, USA Food and Drug Administration.

Data Source

The major product of this initiative was a dynamic database (the UDI Research database or UDIR) that is a dataset generated from Mercy’s data warehouse, that contains UDI-associated coronary stent attribute data and clinical data, and that receives clinical data extracted from the EHR on a weekly basis to enable long term patient follow up. The UDIR, then, provides information that can be used in assessment of device safety and effectiveness.
