Information Extraction and Database Construction for Emergent Patients Based on Voice and Image Recognition Technology
An observational study of Emergencies, run by Seoul National University Hospital at 1 site in South Korea.
Trial summary
Video and audio data of the triage process of emergency department (ED) patients will be collected to build a database. Clinical information retrieved from the database with voice and image technology will be used to determine the triage level of each patient and will be compared with the actual triage level.

About this study
Official title: Triage Information Extraction Technology Development and Database Construction for Emergent Patients Based on Voice and Image Recognition Technology
Video and audio data of the triage process of emergency department (ED) patients will be collected to build a database. Clinical information retrieved from the database with voice and image technology will be used to determine the triage level of each patient and will be compared with the actual triage level.
Read the detailed description
Study Objectives:
- To develop a platform to record video and audio data of the ED triage process.
- To retrieve clinical information using voice and image technology.
- To develop a tool to determine ED triage level using voice and image technology.
- To build a clinical database using video and audio data using voice and image technology.
Study design: Single center observational study (tertiary hospital emergency department in Korea).
A platform to record video and audio data of the ED triage process will be developed. The camera and microphone will be installed at an optimal location to retrieve video and audio data in the ED triage area.
Voice and image technology will be used to retrieve clinical information including demographic information, chief complaint, type and onset of symptoms, past medical history, and physical examination results to build a database. Clinical information including examination notes, diagnosis, patient vital signs, test results, and ED results will be retrieved from the hospital database.

What is being measured
The primary outcome is the main question the study is designed to answer.
The degree of agreement between emergency department triage level retrieved using voice/image technology and by nurses/physicians.
Korean triage and acuity scale (KTAS) which was developed based on Canadian triage and acuity scale (CTAS) is used in Korea. KTAS is composed of 5 levels: level 1, resuscitation; level 2, emergent; level 3, urgent; level 4, less urgent; level 5, non-urgent. Emergency department triage level will be assessed by using voice/image technology and will be compared with the triage level assessed by nurses/physicians. The triage level will be assessed during emergency department triage.
Measured: At the time of study completion (May 2022 anticipated).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Video and audio data of the triage process of emergency department (ED) patients will be collected to build a database. Clinical information retrieved from the database with voice and image technology will be used to determine the triage level of each patient and will be compared with the actual triage level.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The degree of agreement between emergency department triage level retrieved using voice/image technology and by nurses/physicians. (time frame: At the time of study completion (May 2022 anticipated).). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
