This single-center, single-blind, randomized controlled trial evaluates whether the use of a conversational large language model (LLM)-based AI agent, used by caregivers during the waiting period before physician consultation in a pediatric emergency department (ED), affects the caregiver-perceived effectiveness of clinical information delivery compared with standard care. The AI agent collects and summarizes the child's symptoms via voice before the consultation and does not participate in any diagnostic, prescribing, or treatment decisions. A total of 34 caregivers were enrolled at Samsung Medical Center.
Caregivers (aged 19 years or older) of children (younger than 18 years) presenting to the Samsung Medical Center pediatric emergency department (ED) were randomized 1:1 (computerized block randomization, block size 4) to an intervention or control group after providing written informed consent. The intervention group used the AI agent on a study tablet for approximately 5 to 10 minutes during the pre-consultation waiting period; the control group received standard care. All outcomes were assessed once by electronic questionnaire after the ED visit. The primary outcome was the caregiver-perceived effectiveness of clinical information delivery (a 5-item, 5-point Likert instrument). Secondary outcomes included ED physician consultation experience and communication/service experience, AI agent evaluation (intervention group only), ED length of stay, and AI agent usage logs. The outcome assessor (data analyst) was blinded to group allocation; participants could not be blinded due to the nature of the intervention. The AI agent was developed as part of the Ministry of Health and Welfare "Life Careverse" project and functions solely as a pre-consultation history-taking support tool; all clinical decisions were made by the treating physicians.

Exclusion Criteria:
Caregivers used the LLM-based AI agent on a study tablet for approximately 5 to 10 minutes during the pre-consultation waiting period, before the physician consultation.
Other: AI Agent (conversational LLM pre-consultation history-taking tool)
Caregivers received usual pediatric emergency department care without using the AI agent.
A conversational large language model (LLM)-based AI agent used by caregivers on a study tablet before the physician consultation to collect and summarize the child's symptoms. It functions as a pre-consultation history-taking support tool and does not make diagnostic, prescribing, or treatment decisions.
Caregiver-perceived effectiveness of clinical information delivery (PART 2-1)
Caregiver-perceived effectiveness of clinical information delivery, measured with an investigator-developed exploratory instrument (PART 2-1). Five items on a 5-point Likert scale (total score range 5 to 25); higher scores indicate better perceived information delivery.
Time frame: Once, after completion of the index emergency department visit (assessed within approximately 1 hour after ED discharge)
ED communication and service experience (PART 1 and PART 2-2 to 2-9)
Caregiver-reported emergency department physician consultation experience and communication/service experience, assessed in both groups using an 11-item questionnaire (PART 1 plus PART 2-2 to 2-9) rated on a 5-point scale; higher scores indicate a better experience.
Time frame: Within 1 hour after emergency department discharge
Emergency department length of stay
Total emergency department length of stay (in minutes), calculated from the arrival time to the discharge time extracted from the electronic medical record.
Time frame: From emergency department arrival to discharge, assessed up to 24 hours
