STUDY OBJECTIVE Few investigations have been performed that address why emergency department (ED) crowding is associated with an increase in hospital mortality for emergency patients. The purpose of this study was to evaluate whether ED crowding is associated with delayed resuscitation efforts (DREs) that resulted in hospital mortality. METHODS This is a(More)
BACKGROUND The goal of this study is to better understand the trend in epidemiological features and the outcomes of emergency medical service (EMS)-assessed out-of-hospital cardiac arrest (OHCA) according to the community urbanization level: metropolitan, urban, and rural. METHODS This study was performed within a nationwide EMS system with a(More)
OBJECTIVE It is unclear whether advanced airway management during ambulance transport is associated with improved out-of-hospital cardiac arrest (OHCA) outcomes compared with bag-valve mask ventilation (BVM). This study aimed to determine whether EMT-intermediate ETI or LMA is associated with improved OHCA outcomes in Korea. METHODS We used a Korean(More)
OBJECTIVES The objective was to compare the predictive performance of three previously derived cranial computed tomography (CT) rules, the Canadian CT Head Rule (CCHR), the New Orleans Criteria (NOC), and National Emergency X-Ray Utilization Study (NEXUS)-II, for detecting clinically important traumatic brain injury (TBI) and the need for neurosurgical(More)
OBJECTIVE This study aimed to determine whether active post-resuscitation care (APRC) was associated with improved out-of-hospital cardiac arrest (OHCA) outcomes on a nationwide level. METHODS AND RESULTS We used a national OHCA cohort database consisting of hospital and ambulance data. We included all survivors of OHCA, excluding patients with(More)
BACKGROUND It has been previously established that the incidence of burn is higher in lower socioeconomic (SES) groups. What is not clear, however, is whether or not the severity of burn is also higher in lower SES groups. The purpose of this study is to establish a relationship between household-level socioeconomic status (SES) and severity-based incidence(More)
OBJECTIVE This study aims to know if the level of S100B protein at the initiation of cardiopulmonary resuscitation (CPR) and immediately after return of spontaneous circulation (ROSC) can predict clinical outcome. MATERIALS AND METHODS A prospective observational study from December 2004 to October 2006 was conducted in an urban tertiary hospital(More)
PURPOSE Our study compared clinical decision time between patients managed with a point-of-care chemistry test (POCT) and patients managed with the traditional central laboratory test (CLT). BASIC PROCEDURE This was a randomized controlled multicenter trial in the emergency departments (EDs) of 5 academic teaching hospitals. We randomly assigned patients(More)
We developed a hands-free portable device which can provide two-way, real-time audio and video communication between hospital doctors and emergency medical technicians (EMTs) providing pre-hospital care. The device was based on an ultra mobile PC with a camera, a microphone/earphone set and a WIBRO modem for wireless Internet connection at an average data(More)
BACKGROUND The Pan Asian Resuscitation Outcomes Study (PAROS) Clinical Research Network (CRN) was established in collaboration with emergency medical services (EMS) agencies and academic centers in Japan, Singapore, South Korea, Malaysia, Taiwan, Thailand, and UAE-Dubai and aims to report out-of-hospital cardiac arrests (OHCA) and provide a better(More)
