Hvordan vi evaluerer risiko for hallusinasjoner i klinisk AI

Notats bevishistorie er ikke en magisk nøyaktighetsprosent. Det er en transparent metodikk: ekstraher kliniske fakta først, generer notater fra disse faktaene, vis den rå konteksten til klinikeren, og gjennomgå hvert resultat mot bevisene.

Evalueringsmetode

1. Build the reference facts

A reviewer reads the encounter material and creates a reference set of clinical facts: symptoms, negatives, medication changes, assessment, plan, safety-netting, and coding-relevant details.

2. Compare transcript-direct output

We generate a note from transcript-style input and mark unsupported statements, missing high-salience facts, incorrect attribution, and invented certainty.

3. Compare FactsContext output

We generate documentation from extracted facts and review whether each sentence is supported by a visible fact. The clinician-facing fact list is evaluated as part of the output, not hidden.

4. Record limits, not magic numbers

We do not publish fake accuracy percentages. Each evaluation note includes dataset scope, review date, known limitations, and examples of what the system still requires clinicians to verify.

Hva gjennomgangspersoner markerer

Unsupported clinical assertion

Wrong medication, dose, frequency, or route

Missing red-flag negative or safety-net advice

Wrong diagnosis certainty: possible vs established

Wrong speaker attribution

Unsupported ICD-10 suggestion

Clinician-visible evidence for each key statement

Facts reusable for notes, codes, referrals, and patient instructions

Datert internt notat

Gjeldende evalueringsnotat, 2026-07-01: denne siden dokumenterer metoden og kvalitative eksempler brukt til å evaluere FactsContext-arkitekturen. Den hevder ikke ekstern validering eller universell nøyaktighet. Det neste bevismilepælet bør være en blindet, spesialitetsstratifisert gjennomgang med datasettstørrelse, gjennomgangspersonenes enighet og rate for ustøttede utsagn rapportert åpent.

Faktaekstrahering vs. transkripsjonsdirekte generering

Medication change discussed twice

Transkripsjonsdirekte risiko

“Increase amlodipine to 10 mg and stop lisinopril.” The transcript contained a correction: the clinician first considered stopping lisinopril, then decided to continue it after reviewing renal function.

FactsContext-resultat

Facts: amlodipine increased to 10 mg daily; lisinopril continued; renal function normal; review in 6 weeks. Note generated from those facts only.

Hvorfor det er viktig

Transcript-direct generation can smooth over corrections. FactsContext preserves the final decision as a discrete fact before writing.

Negative finding matters

Transkripsjonsdirekte risiko

“No neurological symptoms.” The actual encounter only documented no saddle anesthesia and no bladder symptoms; leg radiation was present.

FactsContext-resultat

Facts: left leg radiation to calf; SLR positive left; no saddle anesthesia; no bladder or bowel symptoms. Note keeps the negatives specific.

Hvorfor det er viktig

Broad negative statements are risky. The fact list keeps the clinical context granular and reviewable.

Code suggestion requires evidence

Transkripsjonsdirekte risiko

Suggested J44.1 for COPD exacerbation without showing the symptom or treatment evidence.

FactsContext-resultat

Facts: increased breathlessness, purulent sputum, prednisolone burst, antibiotics started. Suggested J44.1 with those facts as evidence.

Hvorfor det er viktig

The code is easier to verify because the reason for the suggestion is visible, not buried in prose.

Kjente begrensninger

Clinician review remains mandatory. Notat drafts; clinicians verify and sign.

The method reduces unsupported statements by architecture, but no clinical AI should claim zero hallucinations.

Small internal evaluations are useful for engineering direction, not a substitute for external clinical validation.

Specialty, language, audio quality, speaker overlap, and local coding rules can change performance.

Les bevisene, og inspiser deretter dine egne fakta.

Evalueringsmetoden er enkel fordi produktet er designet for å kunne inspiseres: fakta først, notat andre, klinisk gjennomgang alltid.
