View Article and Find Full Text PDFIntroduction: The day of the week or time of day that surgery is performed may influence postoperative mortality or complications. We aimed to examine whether surgery under general anaesthesia performed after-hours was associated with increased rates of mortality and morbidity, compared with surgery performed in-hours.
Methods: This population-based cohort study obtained data for patients who underwent surgery under general anaesthesia from the National Health Insurance Service of South Korea.
Background: In this population-based cohort study involving a nationwide database from South Korea, we aimed to determine whether rapid response system (RRS) implementation is associated with mortality and morbidity after surgery under general anesthesia.
Methods: Patients who underwent surgery under general anesthesia at the hospital between January 1, 2021, and December 31, 2021. Patients admitted to hospitals with an RRS were categorized into the RRS group, whereas those without an RRS were categorized into the non-RRS group.
Background: Spinal cord stimulators (SCSs) are used to reduce pain and improve quality of life in patients with complex regional pain syndrome (CRPS). However, many patients opt for device removal after SCS implantation due to diminished effect or complications. There is limited research on the actual duration of SCS use in CRPS patients, and no nationwide population-based studies exist.

Methods: This nationwide, retrospective, population-based cohort study included patients who underwent cranial neurosurgery under general anesthesia between January 1, 2016, and December 31, 2021. The two study endpoints were 90-day mortality and postoperative complications.
Article Synopsis
- Hospitals use rapid response systems (RRSs) to quickly address patients whose health worsens post-admission, but their effectiveness in cranial neurosurgery had not been studied until now.
- This study analyzed data from over 73,000 patients who underwent cranial neurosurgery in South Korea between 2019 and 2021, comparing outcomes between those treated in hospitals with RRSs and those without.
- Findings indicated that RRS deployment significantly reduced in-hospital mortality rates and one-year all-cause mortality rates, suggesting improved survival outcomes for cranial neurosurgery patients.
Article Synopsis
- The study examined the impact of Rapid Response Systems (RRS) on patient outcomes in orthopedic surgery, focusing on mortality and complications.
- The analysis included over 931,000 patients in South Korea, comparing those in hospitals with RRS to those in hospitals without it.
- While RRS implementation showed no significant effect on in-hospital mortality, it was linked to a 14% reduction in postoperative complications.
Background: A careful approach is required when providing nutritional support to patients with acute respiratory distress syndrome (ARDS). This study investigated whether implementing a multidisciplinary nutritional support team (NST) is associated with improved survival outcomes in patients with ARDS.
Methods: In a nationwide population-based cohort study, all adult patients admitted to the intensive care unit (ICU) in South Korea with a primary diagnosis of ARDS from January 1, 2017, to December 31, 2021, were included.
Purpose: This study aimed to determine the prevalence of malnutrition and associated risk factors among intensive care unit (ICU) survivors and to investigate whether malnutrition after ICU admission is associated with long-term survival outcomes.
Materials And Methods: We collected data from a National Health Insurance Service database in South Korea. Adults admitted to the ICU between January 1, 2017, and December 31, 2017, who survived >1 year after the date of ICU admission were included.
Rapid response system and mortality in intensive care unit: a nationwide cohort study in South Korea.

September 2024
The beneficial effects of a rapid response system (RRS) on clinical outcomes in patients admitted to a ward have been established. However, the relationship between RRS implementation and clinical outcomes in patients in the intensive care unit (ICU) has not yet been established. Therefore, we aimed to investigate whether the RRS affects clinical outcomes in critically ill patients admitted to the ICU.
