AI scribe hallucinations — and how Notat prevents them
Why AI medical scribes hallucinate, what it means for patient safety, and how Notat’s patent-pending FactsContext™ engine combats hallucination by generating notes only from verified clinical facts.
What hallucination looks like in a clinical note
A medication dose that was never said. A negative finding that was never examined. A follow-up plan the patient never heard. Language models are trained to produce fluent, plausible text — and in clinical documentation, plausible-but-wrong is the most dangerous failure mode there is.
Why transcript-direct scribes are exposed
When the note is generated straight from a transcript, the model is free to smooth over gaps, merge similar statements, and "complete" patterns it has seen in training data. Review helps, but a clinician re-reading fluent text tends to confirm it — that is exactly how automation bias works.
FactsContext™: understanding before writing
Notat separates the two steps. First, the patent-pending FactsContext™ engine extracts structured clinical facts from the encounter — symptoms, findings, medications, decisions — each anchored to what was actually said. Then the note is generated from those facts alone. A statement without a supporting fact is designed not to appear.
Radical transparency closes the loop
Notat shows the raw extracted medical facts to the clinician alongside the note. Instead of trusting fluent prose, you verify sentences against structured facts — and reuse those facts for coding, referrals, or anything else. You review and sign every note; the difference is that verification is finally practical.
Häufig gestellte Fragen
Can any AI scribe guarantee zero hallucinations?
No system should claim that, and clinician review remains mandatory everywhere. What architecture changes is the failure surface: generating only from extracted, visible clinical facts is designed to reduce unsupported statements and — critically — makes the remaining ones easy to catch.
What is the FactsContext™ engine?
Notat’s patent-pending extraction engine. It turns the clinical conversation into structured, verifiable clinical facts before any documentation is written, and exposes those facts to the clinician.
Does this slow down documentation?
No — the note still appears in seconds. What changes is review: instead of re-listening or guessing, you check the note against the extracted facts and sign.
