Abstract Background Prolonged emergency department length of stay (EDLOS) in critically ill patients leads to increased mortality. This nationwide study investigated patient and hospital characteristics associated with prolonged EDLOS in-hospital mortality adult admitted from the (ED) intensive care unit (ICU). Methods We conducted a retrospective cohort using data National Emergency Department Information System. was defined as an ≥ 6 h. constructed multivariate logistic regression models...
Acute respiratory distress syndrome (ARDS) remains a life-threatening disease. Many patients with ARDS do not recover fully, and progress to terminal lung fibrosis. Angiotensin-converting enzyme (ACE) inhibitor is known modulate the neurohormonal system reduce inflammation prevent tissue However, role of ACE in lungs well understood. We therefore conducted this study elucidate effect renin-angiotensin (RAS) blockage on prognosis ARDS.We analyzed medical records who were admitted intensive...
Although the effect of antihypertensive agents on sepsis has been studied, evidence for survival benefit was limited in literature. We investigated differences sepsis-related outcomes depending drugs given prior to patients with hypertension.Population-based cohort study.Sample Database National Health Insurance Service from 2003 2013 South Korea.Patients over 30 years old who were diagnosed after receiving hypertension treatment.None.Primary outcomes, 30-day and 90-day mortality rates,...
The frequency and clinical manifestation of lung fibrosis accompanied by coronavirus disease (COVID-19) are not well-established. We aimed to identify the factors attributed post-COVID-19 fibrosis. This single-center prospective study included patients diagnosed with COVID-19 pneumonia from 12 April 22 October 2021 in Republic Korea. primary outcome was presence pulmonary on a CT scan 3 months after discharge; risk estimated multiple logistic regression. mean patient age 55.03 ± 12.32 (range...
Negative conversion of sputum culture is a useful marker for predicting treatment outcome and relapse pulmonary tuberculosis (TB). The effect drug resistance on negative with was evaluated in this study.A total 535 patients culture-proven TB were classified into three groups: drug-susceptible (DS), other drug-resistant (ODR), multidrug-resistant/extensively (MDR/XDR). Rates at 4, 8, 12 weeks compared.At 4 treatment, the rate DS group (52.7%) higher than that ODR (30.8%, p=0.003), but not...
Takayasu arteritis is a chronic vasculitis involving the large vessels.At diagnosis, ischemic symptom are usually present in affected vessels.However, fever of unknown origin (FUO) rare as an initial presentation and renders condition difficult to diagnose.In this case report, we describe patient who presented with origin.A 68-year-old female was diagnosed after fluorodeoxyglucose (FDG) positron-emission tomography-computed tomography (PET-CT) performed at prepulseless stage.FDG PET-CT can...
Background This study aimed to evaluate the quality of surgical antibiotic prophylaxis (SAP) in a tertiary hospital. Methods Medical, anesthetic, and nursing records from 27,320 procedures conducted hospital during 2012 were retrospectively reviewed. Three clinical performance indicators SAP (selection antibiotic, timing first administration, duration prophylaxis) included as part National Hospital Evaluation Program (NHEP) Health Insurance Review Assessment Service. In addition, 2 other...
Diagnostic methods for pulmonary tuberculosis (TB) have recently advanced. The aim of this study was to evaluate the changes in TB diagnostic tests that prompted initiation anti-TB treatment over time South Korea, an industrialized country with intermediate burden.Patients diagnosed first halves 2005 and 2013 at a tertiary referral hospital were included. compared between 2 groups patients.A greater proportion patients using bronchoscopy than (26.7% vs. 6.6%, respectively; p<0.001), while...
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is widely used for the diagnosis and staging of lung cancer. However, evidence its usefulness re-biopsy in treated cancer, especially according to previous treatment, limited. We evaluated role EBUS-TBNA diagnostic values patients with different treatment histories.We reviewed medical records who underwent suspicious recurrent or progressive lesions between January 2006 December 2016 at National Cancer Center South...
<b><i>Background:</i></b> Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality, therefore the prediction mortality in COPD patients crucial. In current study, abilities different categorization systems to predict stable from prospective cohort were compared. <b><i>Methods:</i></b> The ability was compared terms discrimination by Harrell’s C (HC) index and calibration using graphical comparison among GOLD (Global...
본 연구에서는 언어 및 언어교육 전공 대학생들이 인공지능과 인공지능 교육에 대해 어떻게 생각하는지, 리터러시를 어느 정도 갖추었는지, 그리고 관련 교육을 받았고, 받는데 어떤 사항이 영향을 주는지 알아보았다. 연구를 위해 설문지를 작성하였고 대학생 112명을 대상으로 설문조사를 하였으며, 설문 응답자 중 일부를 인터뷰를 실시하였다. 연구 결과, 대부분의 응답자가 큰 관심을 보였다. 하지만, 자신의 리터러시는 낮은 것으로 평가하였고, 연령별 편차도 유의미하게 나타났다. 또한 인공지능에 대한 관심과 달리 참여자들 실제로 받은 비율은 상대적으로 낮았는데, 이런 결과에 여러 요인이 주는 이와 같은 결과를 바탕으로 대학생들의 리터러시 함양을 교양 수준에서 체계적으로 제공할 필요가 있음을 제안하고자 한다.
Background/Aims: Although the incidence and mortality of tuberculosis are decreasing in South Korea, number applications for financial assistance with cost treatment made by individuals from vulnerable groups was 3.8 times higher 2019 compared to 2017 (Tuberculosis Relief Belt Project, 2019).Methods: We analyzed data patients who received aid (in period 2014-2018) Tuberculosis which designed assist groups. This study 137 subjects, independent variables included patient factors (age, gender,...
In South Korea, there has been a continuous decrease in the incidence of tuberculosis (TB) attributable to national TB elimination program; however, still poses significant socioeconomic burden. This study aimed analyze factors associated with successful treatment and identify refractory patient groups unfavorable outcomes.
Background This study aimed to determine the proportion of organ donors suitable for donation after circulatory death and investigate current process followed by critical care physicians declaring establish donation. Methods observational involved potential who had recently died discontinuation life support. We conducted an online survey intensivists how these deaths were confirmed. Results Among 177 patients withdrawal life-sustaining treatment across 19 intensive units in 11 institutions,...
Delayed isolation of tuberculosis (TB) can cause unexpected exposure healthcare workers (HCWs). This study identified the predictive factors and clinical impact delayed isolation. We retrospectively reviewed electronic medical records index patients HCWs who underwent contact investigation after TB during hospitalization at National Medical Center, between January 2018 July 2021. Among 25 patients, 23 (92.0%) were diagnosed with based on molecular assay, 18 (72.0%) had a negative acid-fast...
Abstract Identifying additional risk factors for COVID-19 severity in numerous previously healthy patients without canonical clinical remains challenging. In this study, we investigate whether clonal hematopoiesis of indeterminate potential (CHIP), a common aging-related process that predisposes various inflammatory responses, may exert severity. We examine the impact CHIP 143 laboratory-confirmed patients. Both stratified analyses and logistic regression including interaction between show...
