Background: With growing elderly populations, management of patients with acute stroke is increasingly important. In South Korea, the Acute Stroke Quality Assessment Program (ASQAP) has contributed to improving the quality of stroke care and practice behavior in healthcare institutions. While the mortality of hemorrhagic stroke remains high, there are only a few assessment indices associated with hemorrhagic stroke. Considering the need to develop assessment indices to improve the actual quality of care in the field of acute stroke treatment, this study aims to investigate the current status of human resources and practices related to the treatment of patients with acute stroke through a nationwide survey. Methods: For the healthcare institutions included in the Ninth ASQAP of the Health Insurance Review and Assessment Service (HIRA), data from January 2022 to December 2022 were collected through a survey on the current status and practice of healthcare providers related to the treatment of patients with acute stroke. The questionnaire consisted of 19 items, including six items on healthcare providers involved in stroke care and 10 items on the care of patients with acute stroke. Results: In the treatment of patients with hemorrhagic stroke among patients with acute stroke, neurosurgeons were the most common providers. The contribution of neurosurgeons in the treatment of ischemic stroke has also been found to be equivalent to that of neurologists. However, a number of institutions were found to be devoid of healthcare providers who perform definitive treatments, such as intra-arterial thrombectomy for patients with ischemic stroke or cerebral aneurysm clipping for subarachnoid hemorrhage. The intensity of the workload of healthcare providers involved in the care of patients with acute stroke, especially those involved in definitive treatment, was also found to be quite high. Conclusion Currently, there are almost no assessment indices specific to hemorrhagic stroke in the ASQAP for acute stroke. Furthermore, it does not reflect the reality of the healthcare providers and practices that provide definitive treatment for acute stroke. The findings of this study suggest the need for the development of appropriate assessment indices that reflect the realities of acute stroke care.

Gastric cancer is one of the most common cancers in both Korea and worldwide. Since 2004, the Korean Practice Guidelines for Gastric Cancer have been regularly updated, with the 4th edition published in 2022. The 4th edition was the result of a collaborative work by an interdisciplinary team, including experts in gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology, and guideline development methodology. The current guideline is the 5th version, an updated version of the 4th edition. In this guideline, 6 key questions (KQs) were updated or proposed after a collaborative review by the working group, and 7 statements were developed, or revised, or discussed based on a systematic review using the MEDLINE, Embase, Cochrane Library, and KoreaMed database. Over the past 2 years, there have been significant changes in systemic treatment, leading to major updates and revisions focused on this area.Additionally, minor modifications have been made in other sections, incorporating recent research findings. The level of evidence and grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation system. Key factors for recommendation included the level of evidence, benefit, harm, and clinical applicability. The working group reviewed and discussed the recommendations to reach a consensus. The structure of this guideline remains similar to the 2022 version.Earlier sections cover general considerations, such as screening, diagnosis, and staging of endoscopy, pathology, radiology, and nuclear medicine. In the latter sections, statements are provided for each KQ based on clinical evidence, with flowcharts supporting these statements through meta-analysis and references. This multidisciplinary, evidence-based gastric cancer guideline aims to support clinicians in providing optimal care for gastric cancer patients.

Purpose: To investigate the prevalence of copper, zinc, and vitamin D deficiencies in surgical intensive care unit (SICU) patients and the associations between those deficiencies and clinical outcomes. Methods: We conducted a retrospective study of 210 patients admitted to the SICU of Asan Medical Center between June 2020 and June 2022. Micronutrient levels were measured within 7 days of SICU admission. Primary outcomes were the mortality rate, length of SICU stay, hospital stay duration, and mechanical ventilation duration. Results: Copper deficiency was found in 35% (68/193), zinc deficiency in 52% (100/193), and severe vitamin D deficiency in 46% (82/179) of patients. Copper-deficient patients showed a significantly higher mortality rate (25.0% vs. 12.8%, P=0.044), longer hospital stays (57.8±47.0 vs. 45.2±36.6 days, P=0.041), and extended mechanical ventilation duration (26.9±23.3 vs. 18.8±15.7 days, P=0.012). Zinc deficiency was associated with higher C-reactive protein levels (16.2±9.5 vs. 11.5±8.8 mg/dL, P=0.001) and lower prealbumin levels (6.5±2.8 vs. 9.9±5.6 mg/dL, P<0.001). Severe vitamin D deficiency (<10 ng/mL) was not significantly associated with mortality or other clinical outcomes (mortality:<10 ng/mL vs. ≥10 ng/mL, 13% vs. 18%, P=0.583). Conclusion Micronutrient deficiencies are prevalent in SICU patients. Copper deficiency significantly correlated with poor clinical outcomes, and zinc deficiency showed a strong association with inflammatory markers. Early assessment and supplementation of micronutrients could be beneficial for critically ill surgical patients.

Purpose: Over the past 3 years, approximately 23,000 emergency surgeries were performed annually in South Korea, accounting for >1% of all surgeries nationwide. With the growing necessity for treating these emergency cases with dedication and proficiency, acute care surgery (ACS) teams were appointed at various hospitals. Regarding the implications of the ACS team, many studies showed promising results with a shorter time from the emergency department (ED) to the operating room (OR), shorter length of stay, and fewer complications. This study aimed to demonstrate the overall effect of ACS implementation at a single institution in South Korea. Methods: This was a single-center, retrospective observational study. Patients aged >18 years who visited the emergency room and received emergency surgery between July 2014 and December 2016 (pre-ACS) and between July 2017 and December 2019 (post-ACS) were included. Results: Among 958 patients, 497 were in the pre-ACS group and 461 in the post-ACS group. After propensity score matching by age, sex, underlying disease, and Emergency Surgery Acuity Score, 405 patients remained in each group. Our analysis showed a reduction in time from ED presentation to operation (547.8 ± 401.0 minutes vs. 476.6 ± 313.2 minutes, P = 0.005) and complication rates (24.7% vs. 16.8%, P < 0.001) in the post-ACS group. There were no significant differences in total operation duration, length of hospital stay, and mortality between the groups. Conclusion As expected, time from ED to OR and complication rates were significantly reduced in the post-ACS group.Implementing an ACS team dedicated to emergency surgery provides better clinical outcomes.
