Miten arvioimme kliinisten tekoälyn hallusinaatioriskiä

Notat'n todistusaineisto ei ole maaginen tarkkuusprosentti. Se on läpinäkyvä menetelmä: poimi kliiniset faktat ensin, tuota merkinnät näistä faktoista, näytä raaka konteksti kliinikolle ja tarkista jokainen tuotos todistusaineistoa vasten.

Arviointimenetelmä

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We do not publish fake accuracy percentages.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.

Mitä arvioijat merkitsevät

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

Päivätty sisäinen merkintä

Nykyinen arviointimerkintä, 2026-07-01: tämä sivu dokumentoi menetelmän ja laadulliset esimerkit, joilla FactsContext-arkkitehtuuria arvioidaan. Se ei väitä ulkoista validointia tai yleistä tarkkuutta. Seuraavan todistusvauhdinkiven tulisi olla sokkoutettu, erikoisaloittain kerrostettu arviointi, jossa tietojoukon koko, arvioijien yhteisymmärrys ja tukemattomien väitteiden osuus raportoidaan avoimesti.

Faktojen poiminta vs. suoraan transkriptiosta tuottaminen

Medication change discussed twice

Suoraan transkriptiosta -riski

“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-tuotos

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

Miksi se on tärkeää

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

Negative finding matters

Suoraan transkriptiosta -riski

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

FactsContext-tuotos

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

Miksi se on tärkeää

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

Code suggestion requires evidence

Suoraan transkriptiosta -riski

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

FactsContext-tuotos

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

Miksi se on tärkeää

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

Tunnetut rajoitukset

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.

Lue todistusaineisto ja tarkista sitten omat faktasi.

Arviointimenetelmä on yksinkertainen, koska tuote on suunniteltu tarkasteltavaksi: faktat ensin, merkintä toiseksi, kliinikon tarkistus aina.
