BACKGROUND: The diagnosis of a sternal fracture is often difficult when the fracture site shows only minimal displacement on conventional radiography. Recently, sonography (US) has been used widely in the emergency room (ER). We investigated the diagnostic performance of US in the ER for the diagnosis of sternal fractures. METHOD: Thirty-six consecutive patients examined for pain and tenderness in the sternum after blunt chest trauma were enrolled in the study. Antero-posterior and lateral radio

BACKGROUND AND PURPOSE: We aimed to evaluate the lactate/albumin ratio (LAR) to identify its significance as a prognostic marker for favorable neurologic outcome and survival in patients with return of spontaneous circulation after out-of-hospital cardiac arrest (OHCA). Based on the LAR and multiple parameters, we developed new nomograms and externally validated the tools. METHODS: We conducted an observational study using a prospective, multicenter registry of out-of-cardiac arrest resuscitatio

BACKGROUND: The Clinical Frailty Scale (CFS) is a representative frailty assessment tool in medicine. This systematic review and meta-analysis aimed to examine whether frailty defined based on the CFS could adequately predict short-term mortality in emergency department (ED) patients. METHODS: The PubMed, EMBASE, and Cochrane libraries were searched for eligible studies until December 23, 2021. We included studies in which frailty was measured by the CFS and short-term mortality was reported for

Script-based CPR team training resulted in comparable improvements in team dynamics scores compared with conventional simulation training. Resuscitation scripts may be used as an adjunct for CPR team training.

BACKGROUND: With an aging population, the number of elderly individuals exposed to traumatic injuries is increasing. The elderly age criterion for traumatic injuries has been inconsistent in the literature. This study aimed at specifying the elderly age criterion when the traumatic mortality rate increases. METHODS: This is a multicenter retrospective cohort study that was conducted utilizing the data from the Emergency Department-based Injury In-depth Surveillance Registry of the Korea Disease

PURPOSE: Acute pulmonary embolism (PE), frequently seen in the emergency department (ED), is a leading cause of cardiovascular morbidity and mortality. The delta neutrophil index (DNI) reflects the fraction of circulating immature granulocytes as a component of the systemic inflammatory response syndrome criteria. The pathogenesis of acute PE is significantly associated with inflammation. The aim of the study was to investigate the clinical usefulness of the DNI as a marker of severity in patien

The DNI can be measured rapidly and simply at ED admission without additional cost or time burden. Increased DNI values independently predict 30-day mortality in patients with UGIH.

BACKGROUND AND PURPOSE: The early prediction of acute kidney injury (AKI) in sepsis and provision of timely treatment may improve outcomes. We investigated the efficacy of the delta neutrophil index (DNI)-which reflects the fraction of immature granulocytes-in predicting sepsis-induced AKI and 30-day mortality in cases of severe sepsis or septic shock. METHODS: This retrospective, observational cohort study was performed with patients prospectively integrated in a critical pathway of early-goal-
