Background: Burnout among healthcare professionals is a critical factor which affects patient safety, treatment outcomes, and the quality of care. This is especially important for hospitalists who manage inpatient care, yet no studies have been conducted on this issue in Korea. This study aimed to investigate burnout and psychiatric symptoms among hospitalists in Korea, as well as to identify the risk and protective factors associated with these issues.

J Gen Intern Med
February 2025
Background: Although the roles and responsibilities of hospitalists have grown considerably in recent years, research on the current job status and satisfaction levels of Korean hospitalists is lacking.
Objective: We investigate the present state of Korean hospitalists and the factors influencing their job satisfaction 6 years after the pilot program's launch.
Design: This cross-sectional analysis was based on an online survey conducted from January 30 to February 18, 2023.
Article Synopsis
- The study investigates how age and sex influence the relationship between muscle mass and serum creatinine levels in healthy individuals, particularly among older adults.
- Researchers analyzed a total of 6,088 people from two national health surveys in Korea, measuring their muscle mass and serum creatinine using advanced imaging and analysis techniques.
- Findings reveal that older males experience a significant decrease in both muscle mass and serum creatinine levels, whereas these trends are not present in older females, highlighting a gender difference in muscle mass loss with age.
Article Synopsis
- Serum creatinine can overestimate kidney function in older patients with low muscle mass, so researchers looked at calf circumference (CC) as a possible alternative.
- A study of 271 hospitalized patients aged 65 and older found that CC measurements correlated well with the ratio of cystatin C to creatinine, which helps identify hidden renal impairment (HRI).
- The findings suggest that using specific CC cutoffs could serve as an effective and cost-efficient way to detect HRI in elderly males, potentially leading to more accurate kidney function assessments.
The prediction of corticosteroid responses in coronavirus disease 2019 (COVID-19) patients is crucial in clinical practice, and exploring the role of artificial intelligence (AI)-assisted analysis of chest radiographs (CXR) is warranted. This retrospective case-control study involving mild-to-moderate COVID-19 patients treated with corticosteroids was conducted from 4 September 2021, to 30 August 2022. The primary endpoint of the study was corticosteroid responsiveness, defined as the advancement of two or more of the eight-categories-ordinal scale.

Patients who were admitted due to COVID-19 from September 2021 to March 2022 were retrospectively included. A commercial AI-based software was used to assess CXR data for consolidation and pleural effusion scores.

J Korean Med Sci
January 2023
Article Synopsis
- The study investigated the household secondary attack rates (SAR) of the omicron and delta variants of SARS-CoV-2, focusing on how vaccination status affected transmission among household members.
- It included 92 index cases and 197 contacts, measuring variant type and antibody levels, while analyzing SAR through statistical methods.
- Results showed a higher SAR for omicron (42%) compared to delta (27%), and higher immunity (like booster doses) in vaccinated individuals helped reduce transmission rates within households.
Establishment of muscle mass-based indications for the cystatin C test in renal function evaluation.
Front Med (Lausanne)
November 2022
Background: We aimed to suggest muscle mass-based criteria for using of the cystatin C test for the accurate estimated glomerular filtration rate (eGFR).
Materials And Methods: We recruited 138 Korean subjects and evaluated eGFRcr (derived from Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) based on creatinine) was compared to eGFRcys based on cystatin C as the reference value. The skeletal muscle mass index (SMI) by bioelectrical impedance analysis (BIA) was used as representative of muscle mass.
Article Synopsis
- - The study investigates how antibody levels against the spike protein correlate with COVID-19 disease severity in vaccinated patients infected with Delta and Omicron variants in South Korea from December 2021 to February 2022.
- - Researchers found that higher antibody levels are linked to a reduced risk of symptoms like fever, hypoxia, and elevated C-reactive protein, indicating better clinical outcomes.
- - The findings suggest monitoring antibody levels may be crucial for managing COVID-19 patients, as they can predict the disease's progression, especially in those with lower antibody presence.
