Prognostic value of frailty across age groups in emergency department patients aged 65 and above.

Background: The Clinical Frailty Scale (CFS) is widely utilized for risk stratification in emergency departments (EDs); however, its predictive value across various age groups remains unclear.

Methods: In this retrospective multicenter study, we analyzed 6,310 patients in the ED aged ≥ 65 years, categorized into young-old (65-74 years, n = 2,750), middle-old (75-84 years, n = 2,400), and old-old (≥ 85 years, n = 1,160) groups. According to CFS, patients were categorized as robust (scores 1-3), pre-frail (score 4), or frail (scores 5-9).

Impact of Medical Residency Programs on Emergency Department Efficiency.

: Medical residency programs play a crucial role in emergency departments (EDs). However, clinical processes may differ between EDs staffed with medical residents and those staffed only by attending physicians. This study aims to compare clinical process times and clinical outcomes between these two types of EDs.

Comparison of early warning scores for predicting outcomes in adult and older patients in emergency department: Multicenter study.

Background: Early Warning Scores (EWS), such as the quick Sequential Organ Failure Assessment (qSOFA), National Early Warning Score 2 (NEWS2), and Rapid Emergency Medicine Score (REMS), are widely used for risk stratification in emergency departments (EDs). However, their predictive performance in older patients remains unclear. This study aimed to evaluate and compare the predictive performance of qSOFA, NEWS2, and REMS for ICU admission and in-hospital mortality in adult (18-64 years) and older (≥65 years) ED patients.

The clinical frailty scale improves risk prediction in older emergency department patients: a comparison with qSOFA, NEWS2, and REMS.

Vital signs are essential for monitoring and prognostication in the emergency department (ED); however, they may not fully capture the complexity of frailty in older adults. In this multicenter retrospective study of 932 older patients who visited the EDs of three tertiary university hospitals between August 1 and October 31, 2023, we investigated the prognostic value of the Clinical Frailty Scale (CFS) in older patients in the ED and its potential to improve existing vital sign-based scoring systems. The primary outcomes were hospital admission, intensive care unit (ICU) admission, and in-hospital mortality.

Mobile Admission Process and Administrative Turnaround Time for Hospitalization of Outpatients: A Retrospective Study.

This study compared the time efficiency of the hospital admission process using personal mobile devices to traditional walk-in methods, thereby assessing the effectiveness of the mobile admission process.This retrospective study was conducted at Chung-Ang University Gwangmyeong Hospital in South Korea (August 2022-January 2023). Turnaround times for the walk-in and mobile admission processes were compared.

Comparison of antibiotic resistance rates and outcomes among older adult patients with urinary tract infections living in long- term care hospitals and the community.

Objective: In this study, we compared the proportion of antibiotic resistance between patients who visited the emergency department (ED) with urinary tract infection (UTI) from long-term care hospitals (LTCH), which is a type of long-term care facilities (LTCF) and the community. We assessed the resulting difference in prognosis.

Method: Older adults who visited the ED between January and December 2019 and were diagnosed with UTI were divided into community residents and LTCH residents.

Risk factors for deep neck infection in patients with sore throat and neck pain.

Background: Deep neck infection (DNI) is a potentially life-threatening disease because infections spread quickly, causing se-rious complications. Therefore, more attention is needed than other neck infections, but there are many difficulties due to isolation guidelines in the period of coronavirus disease 2019 pandemic. We investigated the early predictability of DNI through patient symptoms at the first emergency department encounter.

Validity of the Korean triage and acuity scale in older patients compared to the adult group.

Introduction: While many patients visit the emergency department (ED) for various reasons, medical resources are limited. Therefore, various triage scale systems have been used to predict patient urgency and severity. South Korea has developed and used the Korean Triage and Accuracy Scale (KTAS) based on the Canadian classification tool.

Effects of an Initial Single Dose of Intravenous Antibiotics on Emergency Department Revisits Among Elderly Patients with Urinary Tract Infections.

Purpose: Urinary tract infection (UTI) is the second most common infectious disease among older adults. It is important that the treatment strategy used for older patients with UTIs in the emergency department (ED) be adequate. The effectiveness of an initial single dose of intravenous antibiotics in the ED for treating UTIs has not been extensively studied.

The impact of COVID-19 pandemic on revisits to emergency department.

Aim: This study presents the impact of COVID-19 on revisits to the emergency department comparing revisit rates and characteristics between the pre-COVID-19 and COVID-19 periods.

Methods: This multi-center retrospective study included patients over 18 years of age who visited emergency departments during the pre-COVID-19 period and the COVID-19 pandemic. The revisit rates were analyzed according to five age groups; 18-34, 35-49, 50-64, 65-79, and ≥ 80 years, and three revisit time intervals; 3, 9, and 30 days.

A Comparison of Emergency Department Revisit Rates of Pediatric Patients between Pre-COVID-19 and COVID-19 Periods.

Unscheduled revisits to emergency departments (EDs) are important because they indicate the quality of emergency care. However, the characteristics of pediatric patients visiting EDs changed during the coronavirus disease (COVID-19) pandemic, and these changes may have affected their revisit patterns. Therefore, we aimed to compare the ED revisit patterns of pediatric patients between the pre-COVID-19 and COVID-19 periods.

Comparison of the Clinical Process and Outcomes in Patients after Coronavirus Infection 2019 Outbreak.

: The coronavirus infection 2019 (COVID-19) pandemic has affected emergency department (ED) management. Its viral transmission necessitates the use of isolation rooms and personal protective equipment for treating suspected patients, such as those with fever. This delays the time until the first encounter with the patients, thereby increasing the length of stay (LOS) in the ED.
