RESUMO
Objective@#Helicopter emergency medical services (HEMS) have been used for prompt and appropriate transport of trauma patients. South Korea operates a dual HEMS system consisting of the Doctor-HEMS and the EMS-HEMS. This study compared the relevance of evaluation and treatment during transport using the two HEMS systems. @*Methods@#This was a retrospective, single-center cohort study, and 180 trauma patients transported via HEMS from July 2013 to June 2021 were enrolled in the analysis. We compared the appropriateness of evaluation and management between the Doctor-HEMS and the EMS-HEMS using a newly developed checklist based on Advanced Trauma Life Support protocol. @*Results@#In terms of the performance score, the EMS-HEMS was higher with respect to basic management at the scene, especially cervical immobilization and warming (P<0.001). On the other hand, the Doctor-HEMS showed a higher score with respect to monitoring and procedures during transport (P<0.001). The total performance score was higher in the Doctor-HEMS group than in the EMS-HEMS group (P=0.022). @*Conclusion@#The Doctor-HEMS generally showed better performance in the transport of trauma patients, although it showed relatively lower performance with respect to basic care at the scene. The EMS-HEMS displayed a lower performance in monitoring and management during air transport. It is necessary to develop a common checklist for both the Doctor-HEMS and the EMS-HEMS. Through continuous efforts and feedback, the transportation of trauma patients can be improved.
RESUMO
Background@#We conducted a comprehensive meta-analysis of prospective cohort studies to analyze the effect of circulating vitamin D level on the risk of sudden cardiac death (SCD) and cardiovascular disease (CVD) mortality. @*Methods@#Prospective cohort studies evaluating the association between circulating vitamin D and risk of SCD and CVD mortality were systematically searched in the PubMed and Embase. Extracted data were analyzed using a random effects model and results were expressed in terms of hazard ratio (HR) and 95% confidence interval (CI). Restricted cubic spline analysis was used to estimate the dose-response relationships. @*Results@#Of the 1,321 records identified using the search strategy, a total of 19 cohort studies were included in the final meta-analysis. The pooled estimate of HR (95% CI) for low vs. high circulating vitamin D level was 1.75 (1.49–2.06) with I 2 value of 30.4%. In subgroup analysis, strong effects of circulating vitamin D were observed in healthy general population (pooled HR, 1.84; 95% CI, 1.43–2.38) and the clinical endpoint of SCD (pooled HRs, 2.68; 95% CI, 1.48– 4.83). The dose-response analysis at the reference level of < 50 nmol/L showed a significant negative association between circulating vitamin D and risk of SCD and CVD mortality. @*Conclusion@#Our meta-analysis of prospective cohort studies showed that lower circulating vitamin D level significantly increased the risk of SCD and CVD mortality.
RESUMO
Considerable evidence has been published since the 2020 Korean Cardiopulmonary Resuscitation Guidelines were reported. The International Liaison Committee on Resuscitation (ILCOR) also publishes the Consensus on CPR and Emergency Cardiovascular Care Science with Treatment Recommendations (CoSTR) summary annually. This review provides expert opinions by reviewing the recent evidence on CPR and ILCOR treatment recommendations. The authors reviewed the CoSTR summary published by ILCOR in 2021 and 2022. PICO (population, intervention, comparator, outcome) questions for each topic were reviewed using a systemic or scoping review methodology. Two experts were appointed for each question and reviewed the topic independently. Topics suggested by the reviewers for revision or additional description of the guidelines were discussed at a consensus conference. Forty-three questions were reviewed, including 15 on basic life support, seven on advanced life support, two on pediatric life support, 11 on neonatal life support, six on education and teams, one on first aid, and one related to coronavirus disease 2019 (COVID-19). Finally, the current Korean CPR Guideline was maintained for 28 questions, and expert opinions were suggested for 15 questions.
RESUMO
Objective@#Out-of-hospital cardiac arrest (OHCA) is a common cause of death and serious neurological morbidity. Efforts to reduce the mortality due to OHCA focus on the “chain of survival.” The survival rates of OHCA patients are known to be related to prehospital conditions. @*Methods@#Helicopter emergency medical services (HEMS) provide a variety of procedures, such as cardiopulmonary resuscitation (CPR) and other advanced interventions that may improve the prognosis of OHCA patients. HEMS can respond quickly to long-distance or difficult-to-access places. This study attempted to investigate the characteristics of OHCA patients who had utilized inter-hospital air transport. The study was an observational cohort study using prospective data from a single suburban tertiary care hospital over a period of 7 years. The study data were analyzed using the SPSS version 28 software. @*Results@#In the survival group, the cause was more cardiac-related than in the death group (54% vs. 23.4%; P<0.001). CPR by bystanders and defibrillation by the emergency medical technicians were more frequent than in the death group. Also, the initial rhythm of the survivors was mainly VT or VF (48.0% vs. 14.9%; P<0.003). @*Conclusion@#In the HEMS mission with OHCA arrest, the patients with a cardiac origin, witnessed arrest, those with a shockable rhythm and shorter CPR time had a trend towards better survival and neurological outcomes in this study.
RESUMO
Purpose@#Sleep apnea (SA) is a risk factor for coronary artery disease (CAD), and SA and CAD increase the incidence of sudden cardiac arrest (SCA). This study aimed to investigate the effect of SA on the incidence of SCA and explore the effect of varying degrees of SA with or without CAD on the incidence of SCA. @*Materials and Methods@#This prospective multi-center, case-control study was performed using the phase II Cardiac Arrest Pursuit Trial with Unique Registry and Epidemiologic Surveillance (CAPTURES-II) database for SCA cases and community-based controls in Korea. The matching ratio of cases to controls was 1:1, and they were randomly matched within demographics, including age, sex, and residence. The primary variable was a history of SA, and the second variable was a history of CAD. We conducted a conditional logistic regression analysis to estimate the effect of SA and CAD on the SCA risk, and an interaction analysis between SA and CAD. @*Results@#SA was associated with an increased risk of SCA [adjusted odds ratio (AOR) (95% confidence interval, CI): 1.54 (1.16–2.03)], and CAD was associated with an increased risk of SCA [AOR (95% CI): 3.94 (2.50–6.18)]. SA was a risk factor for SCA in patients without CAD [AOR (95% CI): 1.62 (1.21–2.17)], but not in patients with CAD [AOR (95% CI): 0.56 (0.20–1.53)]. @*Conclusion@#In the general population, SA is risk factor for SCA only in patients without CAD. Early medical intervention for SA, especially in populations without pre-existing CAD, may reduce the SCA risk.ClinicalTrials.gov (NCT03700203)
RESUMO
Objective@#Diagnosis of pulmonary thromboembolism (PTE) is essential for preventing serious complications in the emergency department (ED) or intensive care unit. Contrast computed tomography (CT) of the chest is used for confirming pulmonary embolism, but there is a low specificity and radiation- or contrast-related side effects. We developed a novel nomogram to facilitate decision-making for performing contrast CT of the chest in the ED. @*Methods@#A retrospective observational study was conducted to develop a prediction model of PTE. The prediction model was derived from demographic characteristics, clinical history data and results of laboratory tests, ultrasonography and echocardiography. A nomogram was constructed from the variables of the prediction model and validated. @*Results@#A total of 326 patients were analyzed (a training cohort, 260; a validation cohort, 66). Wells’ score, D-dimer level>1,100 ng/dL, positive McConnell’s sign and D-shaped left ventricle were associated with the occurrence of PTE. The overall predictive accuracy of the prediction model was 0.802 (0.748-0.849) (area under the curve with 95% confidence interval). The calibration plots for the probability of PTE showed good agreement between the nomogram prediction and actual probability among cohorts. @*Conclusion@#A novel nomogram using risk stratification, laboratory test and sonographic examination findings is a good screening tool for predicting PTE, and it can be helpful to decide whether an ED physician should perform a contrastenhanced chest CT in the ED.
RESUMO
Purpose@#Acute decompensated heart failure (ADHF) caused by ischemic heart disease is associated with higher mortality and requires immediate diagnosis. Recently, novel methods to diagnose non-ST elevation myocardial infarction (NSTEMI) using high-sensitivity cardiac troponin have been applied. We compared the clinical utility of high-sensitivity troponin I (hS-TnI), delta troponin I, and other traditional methods to diagnose NSTEMI in patients with ADHF. @*Materials and Methods@#This retrospective cross-sectional study was conducted to analyze patients with ADHF who underwent hS-TnI evaluation of 0–2-h protocol in our emergency department. Patients were grouped according to a diagnosis of NSTEMI. @*Results@#A total of 524 ADHF [ADHF with NSTEMI, n=109 (20.8%)] patients were enrolled in this analysis. The mean values of hS-TnI (ng/mL) in the ADHF with and without NSTEMI groups were 2.44±5.60 and 0.25±0.91, respectively. Multivariable analysis revealed that regional wall-motion abnormality, T-wave inversion/hyperacute T wave, and initial and delta hS-TnI were predictive factors for NSTEMI. Laboratory values related to cardiac biomarkers, including hS-TnI [odds ratio (OR) (95% confidence interval, CI): 2.18], and the delta hS-TnI [OR (95% CI): 1.55] were significant predictors of NSTEMI. Moreover, receiver operating characteristic analysis showed that the areas under receiver operating characteristic curves for electrocardiographic abnormalities, initial hS-TnI, and delta hS-TnI were 0.794, 0.802, and 0.773, respectively. @*Conclusion@#For diagnosis of suspected NSTEMI in patients with ADHF, initial hS-TnI assay has similar predictive value as ischemic changes on electrocardiogram and superior predictive value than delta hS-TnI calculated by the 0–2-h protocol.
RESUMO
Background@#It is difficult to diagnose patients with poisoning and determine the causative agent in the emergency room. Usually, the diagnosis of such patients is based on their medical history and physical examination findings. We aimed to confirm clinical diagnoses using systematic toxicological analysis (STA) and investigate changes in the diagnosis of poisoning. @*Methods@#The Intoxication Analysis Service was launched in June 2017 at our hospital with the National Forensic Service to diagnose intoxication and identify toxic substances by conducting STA. Data were collected and compared between two time periods: before and after the initiation of the project, i.e., from June 2014 to May 2017 and from June 2017 to May 2020. @*Results@#A total of 492 and 588 patients were enrolled before and after the service, respectively. Among the 588 after-service patients, 446 underwent STA. Among the 492 before-service patients, 69.9% were diagnosed clinically, whereas the causative agent could not be identified in 35 patients. After starting the service, a diagnosis was confirmed in 84.4% of patients by performing a hospital-available toxicological analysis or STA.Among patients diagnosed with poisoning by toxins identified based on history taking, only 83.6% matched the STA results, whereas 8.4% did not report any toxin, including known substances. The substance that the emergency physician suspected after a physical examination was accurate in 49.3% of cases, and 12% of cases were not actually poisoned. In 13.4% of patients who visited the emergency room owing to poisoning of unknown cause, poisoning could be excluded after STA. Poisoning was determined to be the cause of altered mental status in 31.5% of patients for whom the cause could not be determined in the emergency room. @*Conclusion@#A diagnosis may change depending on the STA results of intoxicated patients.Therefore, appropriate STA can increase the accuracy of diagnosis and help in making treatment decisions.

RESUMO
Objective@#High-quality intensive care, including targeted temperature management (TTM) for patients with postcardiac arrest syndrome, is a key element for improving outcomes after out-of-hospital cardiac arrest (OHCA). We aimed to assess the status of postcardiac arrest syndrome care, including TTM and 6-month survival with neurologically favorable outcomes, after adult OHCA patients were treated with TTM, using data from the Korean Hypothermia Network prospective registry. @*Methods@#We used the Korean Hypothermia Network prospective registry, a web-based multicenter registry that includes data from 22 participating hospitals throughout the Republic of Korea. Adult comatose OHCA survivors treated with TTM between October 2015 and December 2018 were included. The primary outcome was neurological outcome at 6 months. @*Results@#Of the 1,354 registered OHCA survivors treated with TTM, 550 (40.6%) survived 6 months, and 413 (30.5%) had good neurological outcomes. We identified 839 (62.0%) patients with preClinsumed cardiac etiology. A total of 937 (69.2%) collapses were witnessed, shockable rhythms were demonstrated in 482 (35.6%) patients, and 421 (31.1%) patients arrived at the emergency department with prehospital return of spontaneous circulation. The most common target temperature was 33°C, and the most common target duration was 24 hours. @*Conclusion@#The survival and good neurologic outcome rates of this prospective registry show great improvements compared with those of an earlier registry. While the optimal target temperature and duration are still unknown, the most common target temperature was 33°C, and the most common target duration was 24 hours.

RESUMO
OBJECTIVE: We conducted a study to validate the effectiveness of the Korean criteria for trauma team activation (TTA) and compared its results with a two-tiered system. METHODS: This observational study was based on data from the Korean Trauma Data Bank. Within the study period, 1,628 trauma patients visited our emergency department, and 739 satisfied the criteria for TTA. The rates of overtriage and undertriage in the Korean one-tiered system were compared with the two-tiered system recommended by the American College of Surgery-Committee on Trauma. RESULTS: Most of the patient’s physiologic factors reflected trauma severity levels, but anatomical factors and mechanism of injury did not show consistent results. In addition, while the rate of overtriage (64.4%) was above the recommended range according to the Korean criteria, the rate of undertriage (4.0%) was within the recommended range. In the simulated two-tiered system, the rate of overtriage was reduced by 5.5%, while undertriage was increased by 1.8% compared to the Korean activation system. CONCLUSION: The Korean criteria for TTA showed higher rates of overtriage and similar undertriage rates compared to the simulated two-tier system. Modification of the current criteria to a two-tier system with special considerations would be more effective for providing optimum patient care and medical resource utilization.

PURPOSE: Recent basic life support (BLS) guidelines recommend a 30:2 compression-to-ventilation ratio (CV2) or chest compression-only cardiopulmonary resuscitation (CC); however, there are inevitable risks of interruption of high-quality cardiopulmonary resuscitation (CPR) in CV2 and hypoxemia in CC. In this study, we compared the short-term outcomes among CC, CV2, and 30:1 CV ratio (CV1). MATERIALS AND METHODS: In total, 42 pigs were randomly assigned to CC, CV1, or CV2 groups. After induction of ventricular fibrillation (VF), we observed pigs for 2 minutes without any intervention. Thereafter, BLS was started according to the assigned method and performed for 8 minutes. Defibrillation was performed after BLS and repeated every 2 minutes, followed by rhythm analysis. Advanced cardiac life support, including continuous chest compression with ventilation every 6 seconds and intravenous injection of 1 mg epinephrine every 4 minutes, was performed until the return of spontaneous circulation (ROSC) or 22 minutes after VF induction. Hemodynamic parameters and arterial blood gas profiles were compared among groups. ROSC, 24-hour survival, and neurologic outcomes were evaluated at 24 hours. RESULTS: The hemodynamic parameters during CPR did not differ among the study groups. Partial pressure of oxygen in arterial blood and arterial oxygen saturation were lowest in the CC group, compared to those in the other groups, during the BLS period (p=0.002 and p < 0.001, respectively). The CV1 groups showed a significantly higher rate of favorable neurologic outcome (swine CPC 1 or 2) than the other groups (p=0.044). CONCLUSION: CPR with CV1 could promote better neurologic outcome than CV2 and CC.

OBJECTIVE: Clinically, consumptive coagulopathy, such as disseminated intravascular coagulopathy (DIC), is the most important among the common venomous snakebite complications owing to the serious hemorrhage risk associated with this condition. We evaluated the predictive value of the delta neutrophil index (DNI)—a new indicator for immature granulocytes—for DIC diagnosis. METHODS: This retrospective observational study consecutively assessed adult patients with venomous snakebites for over 51 months. Patients were categorized into the no DIC and DIC groups. DNI values were measured within 24 hours after snakebite. RESULTS: Thirty patients (26.3%) developed DIC. The DIC group had significantly higher median initial DNI than the no DIC group (0% vs. 0.2%, P < 0.001). When the DIC group was divided into early and late groups (within and over 24 hours after snakebite, respectively), the DNI of the former was significantly higher than that of the latter and no DIC group. The late DIC group had significantly higher DNI than the no DIC group. Furthermore, DNI positively correlated with the DIC score (r=0.548, P < 0.001). The initial DNI (odds ratio, 4.449; 95% confidence interval, 1.738 to 11.388; P=0.002) was an early DIC predictor. The area under the curve based on the initial DNI’s receiver operating characteristic curve was 0.724. CONCLUSION: DNI values were significantly higher in the DIC group. Additionally, DNI was an early predictor of DIC development in patients with venomous snakebites in the emergency department.

Recent evidence has demonstrated the survival benefits of helicopter transport for trauma patients. The purpose of this study was to evaluate the effectiveness of hospital-based helicopter emergency medical services (H-HEMS) in comparison with ground ambulance transport in improving mortality outcomes in patients with major trauma. Study participants were divided into 2 groups according to type of transport to the trauma center; that is, either via ground emergency medical services (GEMS) or via H-HEMS. The study was conducted from October 2013 to July 2015. Mortality outcomes in the H-HEMS group were compared with those in the GEMS group by using the Trauma and Injury Severity Score (TRISS) analysis. The number of participants finally included in the study was 312. Among these patients, 63 were adult major trauma patients transported via H-HEMS, and 47.6% were involved in traffic accidents. For interhospital transport, the Z and W statistics revealed significantly higher scores in the H-HEMS group than in the GEMS group (Z statistic, 2.02 vs. 1.16; P = 0.043 vs. 0.246; W statistic, 8.87 vs. 2.85), and 6.02 more patients could be saved per 100 patients when H-HEMS was used for transportation. TRISS analysis revealed that the use of H-HEMS for transporting adult major trauma patients was associated with significantly improved survival compared to the use of GEMS.

The objective of this study was to compare the efficacy of cardiopulmonary resuscitation (CPR) with 120 compressions per minute (CPM) to CPR with 100 CPM in patients with non-traumatic out-of-hospital cardiac arrest. We randomly assigned patients with non-traumatic out-of-hospital cardiac arrest into two groups upon arrival to the emergency department (ED). The patients received manual CPR either with 100 CPM (CPR-100 group) or 120 CPM (CPR-120 group). The primary outcome measure was sustained restoration of spontaneous circulation (ROSC). The secondary outcome measures were survival discharge from the hospital, one-month survival, and one-month survival with good functional status. Of 470 patients with cardiac arrest, 136 patients in the CPR-100 group and 156 patients in the CPR-120 group were included in the final analysis. A total of 69 patients (50.7%) in the CPR-100 group and 67 patients (42.9%) in the CPR-120 group had ROSC (absolute difference, 7.8% points; 95% confidence interval [CI], -3.7 to 19.2%; P = 0.183). The rates of survival discharge from the hospital, one-month survival, and one-month survival with good functional status were not different between the two groups (16.9% vs. 12.8%, P = 0.325; 12.5% vs. 6.4%, P = 0.073; 5.9% vs. 2.6%, P = 0.154, respectively). We did not find differences in the resuscitation outcomes between those who received CPR with 100 CPM and those with 120 CPM. However, a large trial is warranted, with adequate power to confirm a statistically non-significant trend toward superiority of CPR with 100 CPM.

PURPOSE: Because carbon monoxide (CO)-intoxicated patients with an alert mental status and only mild cognitive dysfunction may be inadequately assessed by traditional bedside neurologic examination in the emergency department (ED), they may not receive appropriate treatment. METHODS: We retrospectively investigated the incidence and features of cognitive dysfunction using the Korean version of the Mini-Mental State Examination (MMSE-K) in ED patients with CO poisoning with alert mental status. We conducted a retrospective review of 43 consecutive mild CO poisoned patients with a Glasgow Coma Scale score of 15 based on documentation by the treating emergency physician in the ED between July 2014 and August 2015. RESULTS: Cognitive dysfunction, defined as a score of less than 24 in the MMSE-K, was diagnosed in six patients (14%) in the ED. In the MMSE-K, orientation to time, memory recall, and concentration/calculation showed greater impairments. The mean age was significantly older in the cognitive dysfunction group than the non-cognitive dysfunction group (45.3 yrs vs. 66.5 yrs, p<0.001). Among the initial symptoms, experience of a transient change in mental status before ED arrival was significantly more common in the cognitive dysfunction group (32.4% vs. 100%, p=0.003). CONCLUSION: Patients with CO poisoning and an alert mental status may experience cognitive dysfunction as assessed using the MMSE-K during the early stages of evaluation in the ED. In the MMSE-K, orientation to time, memory recall, and concentration/calculation showed the greatest impairment.

PURPOSE: Snowboarding accidents may cause severe injury due to the advanced skills required of Olympic athletes and the faster speed compared to many other sports. The aim of this study was to describe environmental characteristics of snowboarding injuries and to determine the level of medical support using injury analysis. METHODS: A descriptive epidemiology study was conducted with collection of data from the Federation Internationale de Ski (FIS) Snowboard Competition from January 14 to 24 in 2009. Data from the Competition Operation Committee records, medical records and competition regulations were selected for analysis. RESULTS: In this study, 31/524 competitors reported injuries, predominantly sprains and contusions (21 cases), including eight fractures. Analysis of the physical distribution of these injuries indicated ten injuries of an upper extremity (32%), seven of a lower extremity (23%), six in the head/neck region (19%), and five spinal injuries (16%). The majority (23/31) of these injuries occurred during the snowboard cross (SBX) events. Environmental factors including the course visibility and slope conditions impacted the frequency of injury during the competition. In addition, the arrival times of medical teams were longer for the SBX events (260+/-92 sec) than for the Parallel Giant Slalom (202+/-54 sec) and other snowboarding events (<60 sec). CONCLUSION: The frequency and severity of injuries were highest in the SBX competition. For injury prevention, we recommend increased focus on safety on the SBX course, consideration of weather and other environmental conditions, and a rapid emergency medical support response for injury management.

PURPOSE: Bystander cardiopulmonary resuscitation (CPR) and dissemination of its training are essential to improve the survival outcomes of sudden cardiac death. The purpose of this study was to investigate the tri-temporal trend analysis of the national CPR capacity variables and preparedness in a community. METHODS: This nationwide population-based study used structured questionnaire by a telephone survey for CPR in 2007 (n=1,029), in 2011 (n=1,000), and in 2015 (n=1,000). We used stratified cluster sampling to assess the impact of age, gender, and geographic regions. The contents in the questionnaire consisted of CPR awareness, self-efficacy for bystander CPR, prior training status, and willingness of public CPR training. RESULTS: The proportion of CPR awareness and its recent training experience (<2 years) increased from 89.0% and 14.6%, respectively, in 2007 to 88.5% and 18.7% in 2011, and finally to 94.8% and 30.6% in 2015 (both p for trend<0.001). More than 95% of respondents had agreed to mandatory CPR training acquiring a driver's license or CPR education in school. The awareness of Good Samaritan Law was increased from 20.5% in 2011 to 28.7% in 2015; however, the overall values were lower than the other CPR-related awareness and preparedness. CONCLUSION: In Korea, the trends of national CPR capacity index have been increasing during the past decade. However, the public awareness of the Good Samaritan Law was still low. We suggest that promoting the Good Samaritan Law should be the next step in preparing public CPR training in the future.
