Two patient identifiers: designing reliable checks at the point of care

The risk is a mismatch

A correct electronic record does not ensure that the right person receives a service. WHO recommends at least two person-specific identifiers, such as name and date of birth, before care; a room number is unsuitable. The check must connect the patient with the intended service, not merely confirm that a wristband exists. ^[1]

An identifier is not its carrier

Joint Commission explains that a wristband carries identifying information; it is not itself an identifier. Organizations also need processes for people who cannot communicate or whose identity is initially unknown. ^[2] This US interpretation is useful context, rather than a statement of a particular JCI or HA clause.

An ICORP implementation proposal

Map identification checks across registration, medication administration, specimen collection and transfer. Agree the identifier pair used in each setting, then rehearse similar names, unreadable wristbands and unidentified emergency admissions. Make the escalation contact visible when information conflicts, and observe how the process works under routine workload.

Monitor the actual check

Possible local measures include observed correct matching, identity discrepancies and near misses by service area. Review why checks were bypassed and whether corrective actions changed practice. These suggested measures support improvement; they are not an accreditation pass score.
