The goal of this clinical trial is to test giving all medical/non-medical information in the pediatric emergency room(ER).

• Does providing medical/non-medical information to parents of patients visiting the emergency room lower the workload of medical staff?

  60 participants will be randomly assigned to treatment group and control group. Both groups will communicate freely with the researchers through mobile chat service. Treatment group will get information of medical/non-medical information in emergency room and control group will get information if they need. Before leaving the emergency room, both group will fill out a questionnaire related to satisfaction with the emergency room visits. 5 out of 30 participants of each group will be interviewed about their satisfaction with service.

  10 nurses in charge of patients participating in the study record the number of questions directly received and 5 out of 10 nurse will be interviewed about their nursing experience for participants using mobile chatbot service.
