TL;DR: Patient misidentification is driving preventable medical errors, denied claims, duplicate records, and avoidable care costs, with research cited by Imprivata showing 63% of respondents point to registration errors as the main cause and 35% of denied claims tied to inaccurate identification. The governance lesson is that identity proofing at the first touchpoint is a safety control, not an administrative convenience.
NHIMG editorial — based on content published by Imprivata: patient misidentification, duplicate records, and biometric patient access
By the numbers:
- 63% of respondents cited registration errors as the primary cause of misidentification.
- 35% of denied claims result from inaccurate patient identification.
- 84% of respondents agreed that patient misidentification leads to adverse events.
Questions worth separating out
Q: How should healthcare organisations prevent patient misidentification at registration?
A: Healthcare organisations should treat registration as an identity assurance checkpoint, not a form-filling task.
Q: Why do duplicate patient records create both safety and financial risk?
A: Duplicate records split one person across multiple charts, which can delay care, misroute results, and trigger repeat tests.
Q: What do hospitals get wrong about patient identity matching?
A: The common mistake is assuming demographic data is strong enough to bind a patient to one record.
Practitioner guidance
- Strengthen registration identity proofing Require a higher-assurance match at the first point of patient entry so names and dates of birth are not the only binding factors.
- Deploy biometrics where duplicate creation is highest Place biometric verification into registration and repeat encounters where manual matching errors are most common.
- Track identity integrity as a governance metric Measure duplicate records, overlay errors, reconciliation time, and denied claims tied to patient matching so the programme can show risk reduction rather than just cleanup activity.
What's in the full article
Imprivata's full article covers the operational detail this post intentionally leaves for the source:
- Clinical workflow examples showing how registration errors propagate into lab, treatment, and billing systems.
- A closer look at biometric patient matching and how it is applied at the point of registration.
- The cost breakdown behind duplicate records, denied claims, and manual reconciliation work.
- Why patient-facing self-service check-in can improve identity capture in healthcare settings.

Patient misidentification is not a data cleanup problem, it is an identity assurance failure. The article correctly shows that once the wrong record is created or selected, every downstream workflow inherits that error. That makes registration the decisive control point, because later correction cannot fully undo clinical or financial harm. Practitioners should treat patient identity as a governed assurance boundary, not a clerical form field.
A few things that frame the scale:
- 35% of denied claims result from inaccurate patient identification, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap.
A question worth separating out:
Q: How do biometric checks improve patient identity governance?
A: Biometric checks improve governance by adding a higher-assurance identity factor at the moment the record is established or confirmed. They reduce dependence on manually entered demographics and make it harder for duplicate or mismatched records to form. The control works best when tied to registration and repeat encounters, not used as a late correction step.
