Two million notes a week: How Abridge evaluates clinical AI at scale

Ambient documentation has scaled faster than the review process meant to check it.

Expert clinician review remains the gold standard for note quality, but it does not scale to millions of notes a week. That leaves oversight teams working from aggregate scores that flatten the distinctions clinicians actually care about — whether a patient’s words were misattributed to the clinician, whether follow-ups and referrals made it into the note, whether quality holds steady across patient groups.

The result is a widening distance between what a health system approves and what it can verify. And as documentation systems expand into orders, billing and decision support, that distance grows with them.

This whitepaper details how Abridge evaluates clinical note generation: defining granular failure modes, building internal benchmarks from de-identified examples, developing large language model judges weighted by how closely they track clinician preference, and monitoring production traffic continuously rather than at release. It also previews an evaluation dashboard giving AI governance committees and project teams visibility into those results.

What the report covers:

  • A preview of a new Abridge product dashboard that will give AI governance committees and project teams access to evaluation results
  • Why identical annotation instructions do not automatically align an automated judge with expert reviewers
  • How granular failure tracking keeps resolved issues from resurfacing
  • Reporting evaluation results by product, specialty and health system partner
