The FDA’s Unique Device Identification system put a scannable identity on a vast range of medical devices. But a label is potential, not value. The value of UDI is realized only when the identifier is captured at the point of care and carried into systems that can use it — the patient record, the recall infrastructure, the inventory ledger. This last mile is where many UDI investments quietly fail.
The two parts of a UDI, briefly
A UDI combines a device identifier (DI) — the fixed code naming the make and model, and the key into the FDA’s GUDID database — with a production identifier (PI) carrying lot, serial, and expiration data. Capturing both at point of use is what lets a system answer not just “what device” but “which exact unit, from which lot.”
Where capture breaks down
Three gaps recur:
- Workflow. If scanning a device at the point of use adds steps to a busy clinical moment, it gets skipped. Capture has to be designed into the workflow, not bolted onto it — ideally a single scan that serves documentation and inventory at once.
- Documentation fields. The clinical or procedural record must have a place to put the DI and PI. If the only available field is a free-text note, the data is captured but not usable — it cannot be queried, matched to a recall, or aggregated.
- Exchange. Even well-captured UDI data is limited if it cannot travel. Standards that carry device identity between systems — into the EHR, onward to registries — determine whether the capture has reach beyond the originating department.
Why the effort pays off
When UDI capture works end to end, the downstream benefits are concrete. Recalls become targeted: a hospital can identify exactly which patients received units from an affected lot, rather than launching a broad chart review. Adverse-event reports gain precision. And supply data becomes comparable, because everyone references the same identifiers.
The barcode helps
Because GS1’s GTIN is an accepted UDI device identifier, a single GS1 DataMatrix scan can often serve both the supply chain and clinical documentation — one capture, multiple destinations. That overlap is the most promising path to making point-of-care capture sustainable rather than burdensome.
The convener’s view
Point-of-care UDI capture sits at the intersection of supply chain, clinical documentation, and exchange — three domains that rarely report to the same leader. That is exactly the kind of cross-cutting coordination a neutral health-IT body is positioned to facilitate. See our Standards and Connected Devices work areas for related plain-language coverage.
