Objectives: Although medical artificial intelligence (AI) systems that assist healthcare professionals in critical care settingsare expected to improve healthcare, skepticism exists regarding whether their potential has been fully actualized. Therefore,we aimed to conduct a qualitative study with physicians and nurses to understand their needs, expectations, and concerns regardingmedical AI; explore their expected responses to recommendations by medical AI that contradicted their judgments;and d

Background: Ear-loop-type Korean Filter 94 masks (KF94 masks, equivalent to the N95 and FFP2) are broadly used in health care settings in Korea for the coronavirus disease 2019 pandemic. Methods: A prospective randomized open-label study was designed to identify differences in the fitting performance between mask wearing methods in three different types of KF94 mask with ear loops between January to March 2021. General-fitting involved wearing an earloop-type KF94 mask, and tight-fitting involve

Objectives: Smart hospitals involve the application of recent information and communications technology (ICT) innovationsto medical services; however, the concept of a smart hospital has not been rigorously defined. In this study, we aimedto derive the definition and service types of smart hospitals and investigate cases of each type. Methods: A literature reviewwas conducted regarding the background and technical characteristics of smart hospitals. On this basis, we conducted a focusgroup inter

Purpose: For patients with time-critical acute coronary syndrome, reporting electrocardiogram (ECG) findings is the most important component of the treatment process. We aimed to develop and validate an automated Fast Healthcare Interoperability Resources (FHIR)-based 12-lead ECG mobile alert system for use in an emergency department (ED). Materials and Methods: An automated FHIR-based 12-lead ECG alert system was developed in the ED of an academic tertiary care hospital. The system was aimed at

Purpose: The population of senior citizens is rapidly growing in Korea, and this would inevitably result in the increase of elder abuse. This study was designed to survey healthcare providers in the emergency department, who may have a high probability of coming into contact with abused senior citizens, on the awareness of elder abuse, and to evaluate the level of legal knowledge and standard of education amongst these care providers. Methods: This study was a descriptive, cross-sectional survey

아동학대는 최근 가장 심각한 사회 문제 중 하나이다. 아동학대에 대한 의료종사자의 역할은 매우 중요하다. 그러나 의료종사자의 실제 보고 비율은 매우 낮다. 2013년 6월, 2주 동안 실시된 이 설문조사는 응급실 근무자들의 아동학대에 대한 지식, 태도 및 경험을 조사하기 위해 시행되었다. 112명 중 103명(92.0%)의 근무자가 질문에 대답했다. 설문은 응답자의 특성 및 아동학대에 대한 교육, 인식, 지식, 태도, 의심되는 징후를 인식하는 능력을 알아보기 위한 것이다. 54.4%는 자신의 병원에서 아동학대에 관한 충분한 교육을 받지 않았음을 보고하였다. 응답자의 26.2%가 아동학대를 신고하는 방법에 대해 알고 있었다. 실제 보고한 경험이 있는 사람은 4.9%였다. 아동학대를 신고하지 않는 가장 흔한 이유(75.7%)는 아이의 부모에게 질문하는 것이 두렵기 때문이라고 하였다. 응답자의 67.9%는 아동학대를 보고하지 않는 경우, 처벌받을 수 있다는 것을 알지 못하였다. 이 연구는

Purpose: Coronary artery disease is the most commoncause of out-of-hospital cardiac arrest (OHCA). However,there are no definite indications of coronary angiography(CAG) followed by percutaneous coronary intervention(PCI) in patients with OHCA for diagnosis and treatment. The aim of this study was to determine correlation betweenECG findings and results of CAG of patients with return ofspontaneous circulation after OHCA. Methods: We collected data from January 2010 until April2014. CAG was perfo

Emergency Departments (ED) require rapid differentiation of time-sensitive critical conditions. We present a dynamic Clinical Decision Support System (CDSS) utilizing a Time-Aware Retrieval-Augmented Generation (RAG) framework. In a retrospective pilot study of 70 cases (Aortic Dissection, MI, Stroke, and Trauma Controls), the system's Top-1 diagnostic accuracy significantly improved from 69.5% (triage) to 86.7% (discharge). This validates the system's capability to integrate evolving FHIR data

Purpose: Cricothyroidotomy is a critical procedure for managing difficult airways, yet it is infrequently performed, leading to limited familiarity among medical professionals.This study explores the effectiveness of augmented reality (AR)-based training using HoloLens compared to traditional non-head mounted device (HMD) training in teaching cricothyroidotomy.This study aims to confirm the effect of technical practice using AR on participants' performance ability, performance confidence, learni

Background:Emergency Department (ED) length of stay (LOS) is a critical performance indicator in healthcare systems, influencing patient outcomes, overcrowding, and resource utilization. Predicting LOS can enhance patient flow and resource management. While traditional statistical methods have been used, the advent of machine learning (ML) has significantly improved prediction accuracy. This scoping review aims to examine the latest trends in LOS prediction using not only traditional statistical

Background: Therapeutic hypothermia has been recommended as a standard treatment of cardiac arrest patients after return of spontaneous circulation. There are various methods to drop patient’s core body temperature below 33.5oC. We compared the cooling rate of the conventional cooling method using cold saline bladder irrigation with the commercial hydrogel pad in out-of-hospital cardiac arrest (OHCA) patients. Methods: We collected data retrospectively from the Samsung Medical Center hypothermia

This scoping review aims to map the technological landscape of multimodal digital monitoring systems designed to support "aging in place" for older adults by addressing the "contextual blindness" associated with traditional single-sensor approaches. By integrating diverse data streams—including physiological, environmental, and behavioral data—this study explores the current extent and nature of systems used to assess activities of daily living (ADL) and functional health. Following the JBI meth

Objective: Elevated levels of cardiac troponin in chronic kidney disease (CKD) patients admitted to the emergency department (ED) is not well understood and is often ignored. This study aimed to investigate the impact of cardiac troponin I (TnI) levels on the clinical outcome of patients visiting the ED with or without CKD. Methods: In this retrospective single-center cohort study, we enrolled patients visiting the ED without a diagnosis of coronary artery disease (CAD). Elevated cardiac TnI was

Objective: As the cycling population grows, the lack of public awareness about the dangers of cycling while under the influence of alcohol is a signifant problem. The purpose of this study was to investigate the association between alcohol consumption and bicycle-related injuries such as traumatic brain injuries (TBI) and excess mortality ratio-adjusted injury severity score (EMR-ISS). Methods: We conducted a retrospective analysis using data collected from the Korean Emergency Department-based
