Biometric Patient Identification for Hospitals and Medical Records

The problem

How does a registration desk find the right record? Usually by name, date of birth and sometimes a card number. When two patients share a name, the wrong record opens. When the desk finds nothing, a second record is created, and the patient's history is split in two. When a patient uses someone else's card, the history of two people is mixed in one. Each of these errors ends up at the bedside or in a claim.

What you get

Identification at registration

The patient looks at a scanner, and the system returns the record. No spelling of names, no searching by date of birth, no card to forget.

No duplicate records

Every new registration is searched against all enrolled patients, so a returning patient does not get a second record by accident, and getting one on purpose becomes much harder. Existing duplicates surface as patients come back.

Checks where errors are made

The same identification before medication, transfusion, sample collection and procedures, on a tablet at the bedside or a scanner in the lab.

Verified encounters for billing

The visit record carries the biometric check, so claims to insurers and national schemes are backed by proof that the patient was there. See health insurance.

Name search returns three records, iris search returns one — The record is found by the person, not by a name, a card or a date of birth.

Why iris

A hospital needs contactless identification, and it needs it to work for the elderly, for manual workers with worn fingerprints and for patients who cannot hold a finger still. Iris is captured from a distance, changes little over adult life and separates people well enough to search a whole regional patient register. Face is available as a second modality for patients who cannot open their eyes for the scanner.

Deployment

Integration

An API and SDK for your hospital information system or EMR, including open-source systems, and an identity layer that can be shared by a network of facilities. USB scanners at desks, tablets in wards, offline mode for rural clinics with the Edge service.

Where the data lives

On hospital or ministry servers. Biometric templates are kept apart from medical records and linked by a pseudonymous identifier, so a leak of one database does not directly expose the other.

How we start

We recommend starting with the registration desks of one facility. For a few weeks returning patients are enrolled as they come, and the system reports how many of them already have more than one record. This number is a clear argument for the rest of the rollout.
