About the Lab

Professor In Ae Song's research lab focuses on clinical and translational studies in critical care medicine, oncology, and infectious diseases, with a strong emphasis on population-based cohort analyses. The lab investigates the impact of socioeconomic factors, chronic comorbidities, and perioperative anesthetic strategies on clinical outcomes in conditions such as COVID-19, non-small cell lung cancer, and sepsis. Key research directions include the role of socioeconomic status in infectious disease susceptibility, the influence of anesthetic techniques on cancer recurrence, and early nutritional support in septic patients. The lab leverages large national health databases to generate evidence for public health and clinical practice.

Socioeconomic disparity and the risk of contracting COVID-19 in South Korea: an NHIS-COVID-19 database cohort study
Tak Kyu Oh, Jae-Wook Choi, In‐Ae Song
SJR Q1BMC Public HealthOA

BACKGROUND: The relationship between socioeconomic status and the risk of contracting coronavirus disease (COVID-19) remains controversial. We aimed to investigate whether socioeconomic status affected the risk of contracting COVID-19 in the South Korean population. METHODS: The NHIS-COVID-19 database cohort was used in this population-based study. We collected the data of COVID-19 patients who were diagnosed between January 1, 2020 and June 4, 2020 and those of the control population. The incom

Long-Term Oncologic Outcomes for Patients Undergoing Volatile Versus Intravenous Anesthesia for Non-Small Cell Lung Cancer Surgery

SJR Q2Cancer ControlOA

Propofol-based total intravenous anesthesia (TIVA) has been reported to improve long-term outcome following cancer surgery, when compared with inhalation agents. However, such investigational reports are still controversial, and no studies have been conducted in relation to non-small cell lung cancer (NSCLC) surgery. The present study aimed to compare the favorable effects of TIVA versus inhalation agents on recurrence-free survival and overall survival after curative resection of NSCLC. This re

SJR Q1NutrientsOA

The initial nutritional delivery policy for patients with sepsis admitted to the intensive care unit (ICU) has not been fully elucidated. We aimed to determine whether an initial adequate nutrition supply and route of nutrition delivery during the first week of sepsis onset improve clinical outcomes of critically ill patients with sepsis. We reviewed adult patients with sepsis and septic shock in the ICU in a single tertiary teaching hospital between 31 November 2013 and 20 May 2017. Poisson log

BACKGROUND: The impact of underlying chronic respiratory diseases (CRDs) on the risk and mortality of patients with coronavirus disease 2019 (COVID-19) remains controversial. We aimed to investigate the effects of CRDs on the risk of COVID-19 and mortality among the population in South Korea. METHODS: The NHIS-COVID-19 database in South Korea was used for data extraction for this population-based cohort study. Chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD),

Long-Term Glucocorticoid Use and Cancer Risk: A Population-Based Cohort Study in South Korea

SJR Q1Cancer Prevention ResearchOA

Abstract Long-term glucocorticoid (GC) exposure causes immunosuppression; therefore, the risk of cancer may be increased in long-term GC users. We investigated whether long-term GC use is associated with a higher risk of cancer in the population without cancer. A population-based cohort study using data from the National Health Insurance Service was conducted among the South Korean adult population in 2010. Long-term GC users were defined as those who were prescribed a continuous supply of oral

This retrospective cohort study investigated the association between in-hospital survival and two-dimensional (2D) echocardiography within 24 hours after the return of spontaneous circulation (ROSC) in patients who underwent in-hospital cardiopulmonary resuscitation (ICPR) after in-hospital cardiopulmonary arrest (IHCA).

Whether perioperative hyperchloremia can induce postoperative acute kidney injury (AKI) is controversial. We investigated the association between perioperative hyperchloremia and postoperative AKI in patients admitted to the intensive care unit (ICU) after surgery. We performed a retrospective observational study of patients admitted to the surgical ICU at a single tertiary care hospital between January 2011 and June 2016. Our primary objective was to determine whether hyperchloremia or an incre

OBJECTIVES: Patients with pancreatic cancer generally experience increasing pain as their disease progresses, making the titration of opioids difficult. This study aimed to determine a correlation between prescribed opioid doses and survival time in patients with unresectable pancreatic cancer. METHODS: This retrospective observational cohort study in a tertiary care institution reviewed the medical records of patients diagnosed with unresectable pancreatic cancer and treated over a 10-year peri

Effective and adequate opioid use and prevention of postoperative complications are important for enhanced recovery after surgery. We examined the effects of postoperative opioid use and postoperative complications on overall survival and recurrence-free survival after esophageal cancer surgery. This retrospective cohort study analyzed the records of patients diagnosed with esophageal cancer who underwent the Ivor Lewis operation between January 2005 and December 2011. We collected data on total
