RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic resulted in significant disruptions to critical care systems globally. However, research on the impact of the COVID-19 pandemic on intensive care unit (ICU) admissions via the emergency department (ED) is limited. Therefore, this study evaluated the changes in the number of ED-to-ICU admissions and clinical outcomes in the periods before and during the pandemic. METHODS: We identified all adult patients admitted to the ICU through level 1 or 2 EDs in Korea between February 2018 and January 2021. February 2020 was considered the onset point of the COVID-19 pandemic. The monthly changes in the number of ED-to-ICU admissions and the in-hospital mortality rates before and during the COVID-19 pandemic were evaluated using interrupted time-series analysis. RESULTS: Among the 555,793 adult ED-to-ICU admissions, the number of ED-to-ICU admissions during the pandemic decreased compared to that before the pandemic (step change, 0.916; 95% confidence interval [CI] 0.869-0.966], although the trend did not attain statistical significance (slope change, 0.997; 95% CI 0.991-1.003). The proportion of patients who arrived by emergency medical services, those transferred from other hospitals, and those with injuries declined significantly among the number of ED-to-ICU admissions during the pandemic. The proportion of in-hospital deaths significantly increased during the pandemic (step change, 1.054; 95% CI 1.003-1.108); however, the trend did not attain statistical significance (slope change, 1.001; 95% CI 0.996-1.007). Mortality rates in patients with an ED length of stay of ≥ 6 h until admission to the ICU rose abruptly following the onset of the pandemic (step change, 1.169; 95% CI 1.021-1.339). CONCLUSIONS: The COVID-19 pandemic significantly affected ED-to-ICU admission and in-hospital mortality rates in Korea. This study's findings have important implications for healthcare providers and policymakers planning the management of future outbreaks of infectious diseases. Strategies are needed to address the challenges posed by pandemics and improve the outcomes in critically ill patients.

Trauma with prolonged shock can cause systemic capillary leak syndrome regardless of the site of injury and a transfusion can aggravate it. The systemic capillary leak induces both an abdominal compartment syndrome and pulmonary edema, and a transfusion can aggra-vate these sequelae within hours. In our case, 21-year-old man with a penetrating injury in his left thorax experienced delay in rescue and definitive surgery. To manage life-threatening shock, massive blood transfusion and crystalloids had been infused. Cardiopulmonary cerebral resuscitations were performed 2 times during the surgery. Massive amount of pulmonary secretions emitted from his airways with severe hypoxia along with development of massive ascites causing abdominal compartment syndrome, while the surgery was underway. After temporary abdominal closure, he was moved to the intensive care unit and underwent venovenous extracorporeal membranous oxygenation. He recovered without any notable complications. It is important to prevent and correct the shock rapidly by appropriate rescue, controlling the source and infusing less amount of crystalloid and transfusion.

BACKGROUND: Trauma centers with dedicated trauma intensive care units (TICUs) have recently been developed in South Korea. It is hypothesized that TICU nurse staffing is driven not only by the number of patients but also by the work intensity. This study aims to compare nursing workload characteristics between TICUs and non-TICUs. METHODS: A 1-year retrospective study was performed in one TICU and five non-TICUs in a single trauma center from September 2014 to August 2015. Demographic data were collected along with nursing workload characteristics using the Workload Management System of Critical Care Nurses (WMSCN) score. RESULTS: A total of 332 trauma patients in the TICU and 2,346 nontrauma patients in non-TICUs were studied. TICU patients were younger (49.27 vs. 60.44, p < .001) and more frequently male (75.6% vs. 24.4%, p < .001). The most common admission reasons were motor vehicle crash (38.6%) and cardiovascular conditions (24.9%). Both intensive care unit and hospital length of stay were longer in TICU patients (12.72 vs. 5.43, p < .001; and 35.61 vs. 18.16, p < .001), whereas the mortality rates in the TICU were lower (11.1% vs. 15.1%, p < .001). Total WMSCN scores were significantly higher in the TICU (115.99 vs. 110.19; p < .001). CONCLUSIONS: This study found that nursing workload or work intensity was significantly higher in the TICU than in non-TICUs. Further multicenter studies using objective medical severity scores are warranted.

Coronavirus disease was first reported in December 2019, and the World Health Organization declared it as a pandemic on March 11, 2020. The virus is known to attack various vital organs, including the respiratory system. Patients sometimes require positive pressure ventilation and tracheostomy. Because tracheostomy is a droplet-spreading procedure, medical staff should protect themselves against the risk of transmission of this contagious viral disease. In our case, we performed tracheostomy for a 70-year-old man with coronavirus disease 2019 (COVID-19) who had required more oxygen with gradual weakness of respiratory muscle to maintain his arterial oxygen saturation. We focused on the risks of the medical staffs and patients, and minimized them at the same time using temporary balloon over-inflation, pre-operative adjustment of endotracheal tube position, and attachment of a transparent film dressing to the surgical field without stopping the ventilator while following routine safety measures. Fourteen days after the tracheostomy, all participating medical staff members were healthy and asymptomatic. The patient was discharged 105 days after the COVID-19 diagnosis.

RESUMEN
The aim of this study was to investigate the efficiency of domestic physician-staffed helicopter emergency medical service (HEMS) for the transport of patients with severe trauma to a hospital. The study included patients with blunt trauma who were transported to our hospital by physician-staffed HEMS (Group P; n = 100) or nonphysician-staffed HEMS (Group NP; n = 80). Basic patient characteristics, transport time, treatment procedures, and medical treatment outcomes assessed using the Trauma and Injury Severity Score (TRISS) were compared between groups. We also assessed patients who were transported to the hospital within 3 h of injury in Groups P (Group P3; n = 50) and NP (Group NP3; n = 74). The severity of injury was higher, transport time was longer, and time from hospital arrival to operation room transfer was shorter for Group P than for Group NP (P < 0.001). Although Group P patients exhibited better medical treatment outcomes compared with Group NP, the difference was not statistically significant (P = 0.134 vs. 0.730). However, the difference in outcomes was statistically significant between Groups P3 and NP3 (P = 0.035 vs. 0.546). Under the current domestic trauma patient transport system in South Korea, physician-staffed HEMS are expected to increase the survival of patients with severe trauma. In particular, better treatment outcomes are expected if dedicated trauma resuscitation teams actively intervene in the medical treatment process from the transport stage and if patients are transported to a hospital to receive definitive care within 3 hours of injury.

PURPOSE: The purpose of this study was to verify the utility of existing Trauma and Injury Severity Score (TRISS) coefficients and to propose a new prediction model with a new set of TRISS coefficients or predictors. MATERIALS AND METHODS: Of the blunt adult trauma patients who were admitted to our hospital in 2014, those eligible for Korea Trauma Data Bank entry were selected to collect the TRISS predictors. The study data were input into the TRISS formula to obtain "probability of survival" values, which were examined for consistency with actual patient survival status. For TRISS coefficients, Major Trauma Outcome Study-derived values revised in 1995 and National Trauma Data Bank-derived and National Sample Project-derived coefficients revised in 2009 were used. Additionally, using a logistic regression method, a new set of coefficients was derived from our medical center's database. Areas under the receiver operating characteristic (ROC) curve (AUC) for each prediction ability were obtained, and a pairwise comparison of ROC curves was performed. RESULTS: In the statistical analysis, the AUCs (0.879-0.899) for predicting outcomes were lower than those of other countries. However, by adjusting the TRISS score using a continuous variable rather than a code for age, we were able to achieve higher AUCs [0.913 (95% confidence interval, 0.899 to 0.926)]. CONCLUSION: These results support further studies that will allow a more accurate prediction of prognosis for trauma patients. Furthermore, Korean TRISS coefficients or a new prediction model suited for Korea needs to be developed using a sufficiently sized sample.

AIM: To evaluate the CVC-related infection rate according to catheter insertion site and to analyze the risk factors for catheter-related local infections (CRLI) and bloodstream infections (CRBSI) among severe trauma patients. METHODS: We reviewed the medical records of 736 severe trauma patients with an Injury Severity Score of >15. Poisson regression was used to compare the infection rates according to the catheter insertion sites. Univariate analysis of the groups with and without CVC-related infection was used to identify confounding variables for inclusion in multivariate models that were used to identify the risk factors for CRLI and CRBSI. RESULTS: We evaluated 1646 catheter insertions and their duration of insertion and found 1241 subclavian (18,461 days), 251 internal jugular (3454 days), and 154 femoral catheters (1526 days). The CRLI infection rate per 1000 catheter days was significantly lower for subclavian, compared to that for internal jugular (4.83 vs. 9.55, respectively; P < 0.001) and femoral catheters (4.83 vs. 7.93, respectively; P = 0.013). Multivariate logistic regression analysis revealed that catheter insertion duration [odds ratio (95 % confidence interval): 1.035 (1.021-1.050), P < 0.001] and subclavian access [0.532 (0.366-0.775), P < 0.001] were significantly associated with CRLI, while catheter insertion duration [1.024 (1.002-1.046), P = 0.032] was significantly associated with CRBSI. CONCLUSIONS: To reduce the rate of CVC-related infections in severe trauma patients, we suggest that catheters be shifted from the internal jugular or femoral veins to the subclavian vein as soon as possible and that the duration of catheter insertion should be minimized.

In Korea, which still lacks a well-established trauma care system, the inability to transport patients to adequate treatment sites in a timely manner is a cause of low trauma patient survival. As such, this study was conducted to serve as a basis for the establishment of a future trauma transport system. We performed a comparative analysis of the transport time, and treatment outcomes between trauma victims transported by ground ambulance (GAMB) and those transported via the helicopter emergency medical service (HEMS) through the National Emergency Management Agency's 119 reporting system, which is similar to the 911 system of the United States, from March 2011 to May 2014. The HEMS-transported patients received treatment instructions, by remote communication, from our trauma specialists from the time of accident reporting; in certain instances, members of the trauma medical staff provided treatment at the scene. A total of 1,626 patients were included in the study; the GAMB and HEMS groups had 1,547 and 79 patients, respectively. The median transport time was different between 2 groups (HEMS, 60 min vs. GAMB, 47 min, P<0.001) but for all patients was 49 min (less than the golden hour). Outcomes were significantly better in the HEMS compared to the GAMB, using the trauma and injury severity score (survival rate, 94.9% vs. 90.5%; Z score, 2.83 vs. -1.96; W score, 6.7 vs. -0.8). A unified 119 service transport system, which includes helicopter transport, and the adoption of a trauma care system that allows active initial involvement of trauma medical personnel, could improve the treatment outcome of trauma patients.

PURPOSE: The use of 18F-2-deoxy-2-fluoro-D-glucose positron emission tomography-computed tomography as a routine preoperative modality is increasing for gastric cancer despite controversy with its usefulness in preoperative staging. In this study we aimed to determine the usefulness of preoperative positron emission tomography-computed tomography scans for staging of gastric cancer. MATERIALS AND METHODS: We retrospectively analyzed 396 patients' positron emission tomography-computed tomography scans acquired for preoperative staging from January to December 2009. RESULTS: The sensitivity of positron emission tomography-computed tomography for detecting early gastric cancer was 20.7% and it was 74.2% for advanced gastric cancer. The size of the primary tumor was correlated with sensitivity, and there was a positive correlation between T stage and sensitivity. For regional lymph node metastasis, the sensitivity and specificity of the positron emission tomography-computed tomography were 30.7% and 94.7%, respectively. There was no correlation between T stage and maximum standardized uptake value or between tumor markers and maximum standardized uptake value. Fluorodeoxyglucose uptake was detected by positron emission tomography-computed tomography in 24 lesions other than the primary tumors. Among them, nine cases were found to be malignant, including double primary cancers and metastatic cancers. Only two cases were detected purely by positron emission tomography-computed tomography. CONCLUSIONS: Positron emission tomography-computed tomography could be useful in detecting metastasis or another primary cancer for preoperative staging in gastric cancer patients, but not for T or N staging. More prospective studies are needed to determine whether positron emission tomography-computed tomography scans should be considered a routine preoperative imaging modality.
