The multidimensional frailty score based on comprehensive geriatric assessment is more useful than conventional methods for predicting outcomes in geriatric patients undergoing surgery.

The K-FRAIL scale is correlated with the frailty index and is a simple tool to screen for frailty in a clinical setting.

BACKGROUND: Frailty is related to adverse outcomes in the elderly. However, current status and clinical significance of frailty have not been evaluated for the Korean elderly population. We aimed to investigate the usefulness of established frailty criteria for community-dwelling Korean elderly. We also tried to develop and validate a new frailty index based on a multidimensional model. METHODS: We studied 693 participants of the Korean Longitudinal Study on Health and Aging (KLoSHA). We develop

BACKGROUND: With evaluation for physical performance, measuring muscle mass is an important step in detecting sarcopenia. However, there are no methods to estimate muscle mass from blood sampling. METHODS: To develop a new equation to estimate total-body muscle mass with serum creatinine and cystatin C level, we designed a cross-sectional study with separate derivation and validation cohorts. Total body muscle mass and fat mass were measured using dual-energy x-ray absorptiometry (DXA) in 214 ad

Frailty is a common geriatric syndrome characterized by increased risk of disability, hospitalization, and mortality. Hypertension (HTN) is one of the most common chronic medical conditions in the elderly. However, there have been few studies regarding the association between frailty and HTN prevalence, treatment, and control rates. We analyzed data of 4,352 older adults (age ≥ 65 years) from the fifth Korea National Health and Nutrition Examination Survey. We constructed a frailty index based o

OBJECTIVES: Detecting frailty in older adults scheduled for surgery is important to predict the occurrence of adverse outcomes, but because of its complexity, frailty screening is not commonly performed. The objective of the current study was to assess whether frailty can be screened for using automatically measured usual gait speed (UGS) and mid-arm circumference (MAC) in the outpatient clinic. DESIGN: Prospective, cross-sectional study. SETTING: Geriatric center of a tertiary hospital. PARTICI

Potential conflict of interest: Nothing to report. To the Editor: We read the article by Hong et al.1 with great interest because the concept of sarcopenia has been emerging as a major issue in many fields. In the study by Hong et al., sarcopenia was defined by a state of decreased percent muscle mass as skeletal muscle mass index (SMI) of 1 SD below the sex‐specific mean value. They reported that participants in the sarcopenia group had greater body mass index (BMI) as well as high body fat mas

During the past decades, the world's population has continued on its remarkable transition from a state of high birth and death rates to low birth and death rates. As a result, the number of elderly people, and particularly of the very elderly people, is increasing throughout the world. This demographic change has profound implication for medical and health care systems. As more people live to advanced old age, it is important to understand the chronic diseases and health problems which affect t

The misuse and overtreatment of antibiotics in hospitalized patients with community-acquired pneumonia (CAP) can cause multi-drug resistance and worsen clinical outcomes. We aimed to analyze the trends and appropriateness of antibiotic changes in hospitalized patients with CAP and their impact on clinical outcomes. This retrospective study enrolled patients with CAP, aged > 18 years, admitted from January 2017 to December 2021 at Seoul National University Bundang Hospital, South Korea. We examin

Background: Clinical trials are widely used to approve the efficacy and discover adverse reactions of new drugs. However, there has been much concern about the unjustified exclusion of the older adults in clinical trials. The purpose of this study was to assess ageism in clinical trials and to find solution to any discovered discrimination. Methods: An online questionnaire was completed by 1,650 experts including doctors, pharmaceutical staff, and contract research organization members. An offli

Objective: Atrial fibrillation is the common arrhythmia in the elderly, and the average age of atrial fibrillation patients is rising. Elderly patients with atrial fibrillation have high incidence of thromboembolic complication and increasing age is associated with stroke severity. Assessing CHADS-VASc score is pivotal to evaluate substantial morbidity and mortality, especially regarding the increased risk of stroke. In addition, considering bleeding risk with HAS-BLED score is important to bala

BACKGROUND: The hospitalist system has been introduced to improve the quality and safety of inpatient care. As its effectiveness has been confirmed in previous studies, the hospitalist system is spreading in various fields. However, few studies have investigated the feasibility and value of hospitalist-led care of patients with cancer in terms of quality and safety measures. This study aimed to evaluate the efficacy of the Hospitalist-Oncologist co-ManagemEnt (HOME) system. METHODS: Between Janu
