An observational study in All Emergency Department Visits Meeting Eligibility Criteria, sponsored by Yonsei University. Recruiting at 1 site in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2026-09-22.
Sponsored by Yonsei University · Observational
This single-center prospective observational study evaluates whether an on-premise, large language model-based tool (EDnote) that generates a draft history of present illness (HPI) from real-time transcription of the patient-physician encounter produces documentation of higher quality than conventional physician-written HPI in the emergency department. The treating physician writes the conventional HPI blinded to the AI draft. Unedited AI-generated HPI drafts and conventional HPI are compared through blinded review by independent emergency physicians.

Exclusion Criteria:
Adult emergency department patients whose initial encounter was recorded by EDnote. While the treating physician conducts usual care and writes the conventional HPI, EDnote generates an AI HPI draft in the background; the physician remains blinded to the draft. Both HPIs are evaluated by independent raters blinded to document source.
Other: EDnote HPI (AI-generated HPI draft) · Other: Conventional physician HPI
On-premise large language model-based tool that transcribes the patient-physician encounter in real time and generates an unedited HPI draft. The treating physician is blinded to the AI HPI draft.
HPI written by the treating emergency physician according to usual practice, blinded to the EDnote-generated HPI draft.
Encounter-level clinical fact capture rate
Time frame: At blinded review, within 6 months after each index ED visit
Modified PDQI-9 score
Modified Physician Documentation Quality Instrument-9 (Modified PDQI-9) score. The modified instrument consists of 10 items, each rated from 1 to 5, yielding a total score ranging from 10 to 50. Higher scores indicate better documentation quality.
