BACKGROUND: We investigated the diagnostic and prognostic value of presepsin among patients with organ failure, including sepsis, in accordance with the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). METHODS: This prospective observational study included 420 patients divided into three groups: non-infectious organ failure (n = 142), sepsis (n = 141), and septic shock (n = 137). Optimal cut-off values of presepsin to discriminate between the three groups were ev

STUDY OBJECTIVE: We aimed to determine if there are differences in bystander cardiopulmonary resuscitation (BCPR) provision and survival to hospital discharge from out-of-hospital cardiac arrest (OHCA) occurring in Hispanic neighborhoods in Arizona. METHODS: We analyzed a prospectively collected, statewide Utstein-compliant OHCA database between January 1, 2010, and December 31, 2012. Cases of OHCA were geocoded to determine their census tract of event location, and their neighborhood main ethni

Vasoactive and inotropic medications are essential for sepsis management; however, the association between the maximum Vasoactive-Inotropic score (VISmax) and clinical outcomes is unknown in adult patients with sepsis. We investigated the VISmax as a predictor for mortality among such patients in the emergency department (ED) and compared its prognostic value with that of the sequential organ failure assessment (SOFA) score. This single-center retrospective study included 910 patients diagnosed

Fifteen patients underwent computed tomography (CT)-guided contrast material localization of pulmonary nodules, with barium and indigo carmine stain used in five patients, iodized oil and indigo carmine stain in five, and water-soluble contrast material and indigo carmine stain in five before fluoroscopy-assisted thoracoscopic resection. Contrast material localization was successful in all cases, and the surgeon confirmed accurate localization, CT-guided contrast material localization is simple

Implementing appropriate emergency care policies in the COVID-19 pandemic would have contributed to improving the safety of all emergency patients and reducing in-hospital mortality by preventing excessive deaths.

It is inevitable for cancer patients to visit the emergency department (ED) for symptoms of cancer itself and various treatment-related complications. As the prevalence of cancer increases along with cancer survival rates, the number of ED visits of cancer patients may increase. This study aimed to investigate the epidemiologic trends and characteristics of cancer-related ED visits. A cross-sectional study was conducted for all ED visits nationwide between 2015 and 2019. The characteristics of c

During the COVID-19 pandemic, there was excess in-hospital mortality among patients who visited EDs, and there were disparities in excess mortality depending on community socioeconomic positions.

We developed a novel computer program, the Intelligent Sepsis Management System, based on Sepsis-3 definitions and 2016 Surviving Sepsis Campaign guidelines and performed a quasi-experimental pre-post study to assess its effect on compliance with the Surviving Sepsis Campaign guidelines and outcomes in patients with sepsis and septic shock. During the pre-period, patients were managed with usual care. During the post-period, patients were managed using the Intelligent Sepsis Management System up

OBJECTIVES: To evaluate the effects of social distancing on the incidence and characteristics of injuries during the COVID-19 pandemic. DESIGN AND SETTING: This cross-sectional study used the National Emergency Department Information System (NEDIS) database. PARTICIPANTS: Injured patients who visited all 402 emergency departments (EDs) between 29 February and 29 May 2020 (after-distancing), and in the corresponding period in 2019 (before distancing) to control for seasonal influences. OUTCOME ME

Detecting sepsis patients who are at a high-risk of mechanical ventilation is important in emergency departments (ED). The respiratory rate oxygenation (ROX) index is the ratio of tissue oxygen saturation/fraction of inspired oxygen to the respiratory rate. This study aimed to investigate whether the ROX index could predict mechanical ventilator use in sepsis patients in an ED. This retrospective observational study included quick sequential organ failure assessment (qSOFA) ≥ 2 sepsis patients t
