RÉSUMÉ

Objective@#Coronavirus disease 2019 (COVID-19) has notably altered the emergency department isolation protocol, imposing stricter requirements on probable infectious disease patients that enter the department. This has caused adverse effects, such as an increased rate of leave without being seen (LWBS). This study describes the effect of fever/respiratory symptoms as the main cause of isolation regarding LWBS after the COVID-19 pandemic. @*Methods@#We retrospectively analyzed emergency department visits before (March to July 2019) and after (March to July 2020) the COVID-19 pandemic. Patients were grouped based on existing fever or respiratory symptoms, with the LWBS rate as the primary outcome. Logistic regression analysis was used to identify the risk factors of LWBS. Logistic regression was performed using interaction terminology (fever/respiratory symptom patient [FRP] × post–COVID-19) to determine the interaction between patients with FRPs and the COVID-19 pandemic period. @*Results@#A total of 60,290 patients were included (34,492 in the pre–COVID-19, and 25,298 in the post–COVID-19 group). The proportion of FRPs decreased significantly after the pandemic (P < 0.001), while the LWBS rate in FRPs significantly increased from 2.8% to 19.2% (P < 0.001). Both FRPs (odds ratio, 1.76; 95% confidence interval, 1.59–1.84 (P < 0.001) and the COVID-19 period (odds ratio, 2.29; 95% confidence interval, 2.15–2.44; P < 0.001) were significantly associated with increased LWBS. Additionally, there was a significant interaction between the incidence of LWBS in FRPs and the COVID-19 pandemic period (P < 0.001). @*Conclusion@#The LWBS rate has increased in FRPs after the COVID-19 pandemic; additionally, the effect observed was disproportionate compared with that of nonfever/respiratory symptom patients.

RÉSUMÉ

Objective@#As the cycling population grows, the lack of public awareness about the dangers of cycling while under the influence of alcohol is a signifant problem. The purpose of this study was to investigate the association between alcohol consumption and bicycle-related injuries such as traumatic brain injuries (TBI) and excess mortality ratio-adjusted injury severity score (EMR-ISS). @*Methods@#We conducted a retrospective analysis using data collected from the Korean Emergency Department-based Injury In-depth Surveillance (EDIIS) database from 20 emergency departments during the period 2011-2016. The study subjects who had sustained bicycle-related injuries were over 18 years of age. The covariates included the mechanism, place, and time of injury. The outcomes were TBI incidence and severe and critical injury of EMR-ISS≥25. The effects of alcohol consumption on these outcomes were analyzed, and the variations in effects were determined using logistic regression. @*Results@#Of the 24,297 individuals studied, 1,912 had alcohol-related bicycle injuries, which led to a higher proportion of single-vehicle injury incidents (alcohol 63.7% vs. non-alcohol 46.4%, P<0.001). The alcohol group had a higher rate of TBI (alcohol 11.5% vs. non-alcohol 4.6%, P<0.001) and severe and critical injury of EMR-ISS (alcohol 23.1% vs. nonalcohol 11.7%, P<0.001). TBI (odds ratio [OR], 2.72; 95% confidence interval [CI], 2.33-3.16) and severe and critical injury of EMR-ISS (OR, 2.26; 95% CI, 2.01-2.53) showed a significant association with alcohol. @*Conclusion@#Our study showed an association of alcohol consumption with a higher incidence of TBI and severe and critical EMR-ISS. Education should focus more on the association between cycling under alcohol influence and injury severity.

Objective@#Elevated levels of cardiac troponin in chronic kidney disease (CKD) patients admitted to the emergency department (ED) is not well understood and is often ignored. This study aimed to investigate the impact of cardiac troponin I (TnI) levels on the clinical outcome of patients visiting the ED with or without CKD. @*Methods@#In this retrospective single-center cohort study, we enrolled patients visiting the ED without a diagnosis of coronary artery disease (CAD). Elevated cardiac TnI was defined as being ≥99th percentile of the normal population (Siemens ADVIA Centaur TnI-Ultra≥0.040 ng/mL). The clinical outcomes of patients with CKD stage≤2 and CKD stage ≥3 were compared. The primary endpoint was the 180-day all-cause death, including cardiovascular and non-cardiovascular deaths. @*Results@#Among a total of 30,472 patients (median age, 61 years; male sex, 54.3%), elevated TnI was found in 4,377 patients (14.4%). There were 3,634 deaths (11.9%) including 584 cardiovascular (1.9%) and 3,050 non-cardiovascular deaths (10.0%). The risk of all-cause death increased in patients with elevated TnI in both CKD stage≤2 (hazard ratio [HR], 2.1; 95% confidence interval [CI], 1.9-2.3) and CKD stage≥3 (HR, 1.5; 95% CI, 1.4-1.7), and so did the risks of cardiovascular and non-cardiovascular death (HR, 1.2-4.7) (P<0.05, all). The association of elevated TnI with death risk was consistent in multivariate analyses and in most clinical subgroup analyses. @*Conclusion@#Elevated TnI was associated with higher 180-day mortality irrespective of renal function among patients visiting the ED without documented CAD. CKD patients visiting the ED with elevated TnI may warrant additional evaluation or careful follow-up even without the presence of CAD.

Objective@#The utilization of emergency medical services (EMS) varies widely among communities. In this study, we aimed to evaluate the relationship between the use of EMS by patients with ST-elevation myocardial infarction (STEMI) and the individual and neighborhood characteristics of these patients. @*Methods@#We performed a secondary analysis of data from the Cardiovascular Disease Surveillance project, which included patients diagnosed with STEMI at 29 emergency centers in South Korea. Our analysis included only patients living in Seoul, and the primary outcome measured was the use of EMS. While the clinical variables of the patients were collected from the Cardiovascular Disease Surveillance registry, the 2010 National Census data was used to identify neighborhood variables such as population density, income, age, and residence type. We used a 3-level hierarchical logistic regression to estimate the effects of neighborhood-level factors on EMS use by individual patients. @*Results@#We evaluated 1,634 patients with STEMI from 2007 to 2012. The neighborhoods were grouped into 25 counties. The regional rates of EMS use varied from 18.3% to 46.5%. The final adjusted logistic model revealed that the use of EMS was significantly associated with the average number of households (neighborhood level factor) and symptoms of syncope, cardiac arrest, and history of cardiovascular disease (individual level factors). @*Conclusion@#The individual levels factors had a greater influence on the use of EMS compared to the neighborhood-level factors.

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.

Objective@#This study aimed to confirm the accuracy of a machine-learning-based model in predicting the 30-day mortality of patients with pneumonia and evaluating whether they were required to be admitted to the intensive care unit (ICU). @*Methods@#The study conducted a retrospective analysis of pneumonia patients at an emergency department (ED) in Seoul, Korea, from January 1, 2016 to December 31, 2017. Patients aged 18 years or older with a pneumonia registry designation on their electronic medical record were enrolled. We collected their demographic information, mental status, and laboratory findings. Three models were used: the pre-existing CURB-65 model, and the CURB-RF and Extensive CURB-RF models, which were machine-learning models that used a random forest algorithm. The primary outcomes were ICU admission from the ED or 30-day mortality. Receiver operating characteristic curves were constructed for the models, and the areas under these curves were compared. @*Results@#Out of the 1,974 pneumonia patients, 1,732 patients were eligible to be included in the study; from these, 473 patients died within 30 days or were initially admitted to the ICU from the ED. The area under receiver operating characteristic curves of CURB-65, CURB-RF, and extensive-CURB-RF were 0.615 (0.614–0.616), 0.701 (0.700–0.702), and 0.844 (0.843–0.845), respectively. @*Conclusion@#The proposed machine-learning models could predict the mortality of patients with pneumonia more accurately than the pre-existing CURB-65 model and can help decide whether the patient should be admitted to the ICU.

RÉSUMÉ

Background@#Characteristics of coronary vasospasm-related sudden cardiac death are not well understood. We aimed to compare the characteristics and clinical outcomes between coronary vasospasm and stenosis, in out-of-hospital cardiac arrest (OHCA) survivors, who underwent coronary angiogram (CAG). @*Methods@#We conducted a multicenter retrospective observational registry-based study at 8 Korean tertiary care centers. Data of OHCA survivors undergoing CAG between 2010 and 2015 were extracted. Patients were divided into vasospasm and stenosis (stenosis > 50%) groups based on CAG findings. The primary and the secondary outcomes were survival and a good neurologic outcome at 30 days after OHCA. Patients in the vasospasm and stenosis groups were propensity score matched. @*Results@#Of the 413 included patients, vasospasm and stenosis groups comprised 87 and 326 patients, respectively. There were 279 (66.7%) survivors and 206 (49.3%) patients with good neurologic outcomes. The vasospasm group had better clinical characteristics for outcome (younger age, less diabetes and hypertension, more prehospital restoration of spontaneous circulation, higher Glasgow Coma Scale, less ST segment elevation, and less requirement of circulatory support). The vasospasm group had better survival (75/87 vs. 204/326, P < 0.001) and good neurologic outcomes (62/87 vs. 144/326, P < 0.001). However, vasospasm was not independently associated with survival (odds ratio [OR], 0.980; 95% confidence interval [CI], 0.400–2.406) or neurologic outcomes (OR, 0.870; 95% CI, 0.359–2.108) after adjustment and vasospasm was not associated with survival and neurologic outcome in propensity score-matched cohorts. @*Conclusion@#Our analysis of propensity score-matched cohorts finds that vasospasm OHCA survivors have survival and neurologic outcomes comparable with those of stenotic OHCA survivors.

RÉSUMÉ

OBJECTIVES: The aim of this study was to test the applicability of haptic feedback using a smartwatch to the delivery of cardiac compression (CC) by professional healthcare providers. METHODS: A prospective, randomized, controlled, case-crossover, standardized simulation study of 20 medical professionals was conducted. The participants were randomly assigned into haptic-first and non-haptic-first groups. The primary outcome was an adequate rate of 100–120/min of CC. The secondary outcome was a comparison of CC rate and adequate duration between the good and bad performance groups. RESULTS: The mean interval between CCs and the number of haptic and non-haptic feedback-assisted CCs with an adequate duration were insignificant. In the subgroup analysis, both the good and bad performance groups showed a significant difference in the mean CC interval between the haptic and non-haptic feedback-assisted CC groups—good: haptic feedback-assisted (0.57–0.06) vs. non-haptic feedback-assisted (0.54–0.03), p < 0.001; bad: haptic feedback-assisted (0.57–0.07) vs. non-haptic feedback-assisted (0.58–0.18), p = 0.005—and the adequate chest compression number showed significant differences— good: haptic feedback-assisted (1,597/75.1%) vs. non-haptic feedback-assisted (1,951/92.2%), p < 0.001; bad: haptic feedbackassisted (1,341/63.5%) vs. non-haptic feedback-assisted (523/25.4%), p < 0.001. CONCLUSIONS: A smartwatch cardiopulmonary resuscitation feedback system could not improve rescuers' CC rate. According to our subgroup analysis, participants might be aided by the device to increase the percentage of adequate compressions after one minute.

RÉSUMÉ

OBJECTIVE@#Research on calcium use as an adjunctive rescue therapy for refractory septic shock is limited. In this study, we aimed to investigate the short-term hemodynamic response after calcium supplementation in patients with refractory septic shock.@*METHODS@#This was a single-center, retrospective study of patients who presented to the Emergency Department from October 2014 through February 2018. Patients with refractory septic shock requiring norepinephrine-equivalent (NE) dose ≥ 0.5 µg/kg/min and receiving calcium supplementation, were included in the analysis. Patients were categorized into response group and no-response group, based on the changes in NE doses and mean arterial pressure after calcium administration. A multivariable logistic regression model was used to evaluate the association between hemodynamic response and 28-day survival.@*RESULTS@#A total of 66 patients were included in the study. Of these, 34 patients (52%) were classified as the response group, and 32 patients (48%) encompassed the no-response group (17 patients who deteriorated and 15 patients who had no significant changes in the clinical status). The 28-day mortality was determined to be 44% in the response group and 63% in the no-response group (P=0.14). Multivariable analysis revealed that the response group had a significant association with lower 28-day mortality (adjusted odds ratio, 0.23; 95% confidence interval, 0.06–0.89; P=0.03).@*CONCLUSION@#Short-term hemodynamic changes after calcium administration were variable in patients with refractory septic shock. Hemodynamic improvement after calcium supplementation may be associated with better survival. Further studies are required to determine when calcium supplementation needs to be considered, and how it impacts patientcentered outcomes in refractory septic shock.

OBJECTIVE: The benefits of targeted temperature management (TTM) for resuscitated out of hospital cardiac arrest (OHCA) with an initial non-shockable rhythm are still unclear. This study examined whether TTM reduces the mortality and improves the neurological outcomes of OHCA with a non-shockable initial rhythm. METHODS: This study analyzed the clinical outcome of 401 resuscitated patients with an initial non-shockable rhythm among a total of 1,616 OHCA patients who were registered in Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance. The impact of TTM was investigated after accounting for the patients' propensity for TTM. The primary outcome was a 30-day in-hospital course with a neurologically favorable outcome defined by a cerebral performance categories scale ≤2. RESULTS: TTM was performed in 89 patients (22%) with an initial non-shockable rhythm. Patients who has received TTM had a tendency to be younger, more likely to be female, and more likely to undergo percutaneous coronary intervention. The clinical outcome of the patients in the initial non-shockable rhythm treated by TTM was superior to those without TTM (hazard ratio [HR], 0.36; 95% confidence interval [CI], 0.27–0.46). Further analysis after propensity score matching or inverse probability of treatment weighting (IPTW) showed consistent findings (propensity score matching: HR, 0.32; 95% CI, 0.22–0.45; IPTW: HR, 0.40; 95% CI, 0.31–0.52; P<0.001, all). CONCLUSION: In this nationwide OHCA registry, TTM was related to an approximately three-fold better 30-day neurologically favorable survival of resuscitated patients with TTM treatment than patients without TTM in the initial non-shockable rhythm.

RÉSUMÉ

BACKGROUND: Recent studies have reported the association of knee osteoarthritis (KOA) with metabolic risk factors. The objective of this study was to evaluate the association between KOA and metabolic syndrome (MetS).METHODS: The study subjects were 966 Korean adults aged ≥50 years who participated in a free-of-charge health examination provided to residents of a non-urban area. We ascertained KOA and MetS on the basis of the clinical diagnostic criteria of the American Rheumatism Association and the modified National Cholesterol Education Program's Adult Treatment Panel III, respectively. The association between KOA and MetS was evaluated using a multiple logistic regression analysis after adjusting for covariates.RESULTS: The overall prevalence rates of KOA and MetS were 34.9% and 48.7%, respectively, with higher prevalence rates in the women than in the men (P < 0.001). The risk of MetS was significantly higher in the subjects with KOA than in those without KOA (odds ratio [OR], 1.35; 95% confidence interval [CI], 1.03–1.77). Among the components of MetS, only abdominal obesity showed a significant association with KOA (OR, 1.48; 95% CI, 1.12–1.95). When the analyses were repeated to determine sex-specific relationships, the associations of KOA with MetS (P=0.069) and abdominal obesity (P=0.022) were evident in the women, but not in the men.CONCLUSION: The findings of this study suggest that women with KOA must be evaluated and managed for MetS, with special attention to abdominal obesity.

RÉSUMÉ

OBJECTIVE: While the effect of typhoons on emergency medicine has been evaluated, data are scarce on their effects on the emergency medical service (EMS). This study evaluated the effect of typhoons on EMS patients and performance. METHODS: The study period was January 2010 to December 2012. Meteorological data regarding typhoons were provided by the Korean Meteorological Administration. EMS data were retrieved from the EMS database of the national emergency management agency. The database includes ambulance run sheets, which contain clinical and operational data. In this case-crossover study, the cases and controls were EMS calls on the day of typhoon warnings and calls one week prior to the typhoon warnings, respectively. RESULTS: During the study period, 11 typhoons affected Korea. A total of 14,521 cases were selected for analysis. Overall, there were no obvious differences between the case and control groups. However, there were statistically significant differences in age, place, and time requests. There were fewer patients between 0 and 15 years of age (P=0.01) and more unconscious patients (P=0.01) in the case group. The EMS operational performance, as measured by the times elapsed between call to start, call to field, and call to hospital did not differ significantly. There was also no significant difference in the time from hospital arrival between the cases (28.67, standard deviation 16.37) and controls (28.97, standard deviation 28.91) (P=0.39). CONCLUSION: Typhoons did not significantly affect the EMS system in this study. Further study is necessary to understand the reasons for this finding.

RÉSUMÉ

BACKGROUND: Suicide in young people is one of most common cause of death; and deliberate self-harm (DSH) is important indicator of suicide. It is currently unclear how old the rate begins to increase or when it reaches to the same level with adults. The purpose of this study was to find beginning age of DSH and compare their characteristics with adults. METHODS: This study retrospectively reviewed 5 years of nationwide prospective registry named Emergency Department-based Injury In-depth Surveillance (EDIIS) registry composed of all injured patients who were admitted to twenty tertiary university hospital emergency departments. Injured patients aged 29 years or younger from January 1, 2011 to December 31, 2015 were included. Incidence rate of DSH in all age was described. Patients were stratified by age: early teenage (11–15 years), late teenage (16–19 years), and early adulthood (20–29 years). Data of early teenage group were compared to those of other groups for examining their characteristics. RESULTS: Among 588,549 injury patients, 8,400 patients reported DSH. The rate began to rise at age 11 and reach at age 16 which was equivalent to that of age 20 to 29. Early teenage had significantly higher excess mortality ratio based injury severity score (EMR-ISS) and had almost same level without significant difference in operation incidence or mortality compared to late teenage and early adulthood. CONCLUSION: DSH rate began to rise at age 11, reaching adulthood level at age 16 in Korea.

RÉSUMÉ

PURPOSE: In this study, we aimed to measure the effects of emergency department (ED) expansion at a tertiary hospital on overall ED length of stay (LOS). METHODS: This study was a before and after study using data from a tertiary medical center in Seoul, a large metropolis. We used electronic medical records and administrative databases obtained from the ED. The control period (before expansion) was defined as from January 1 to April 31, 2016. The study period (after expansion) was defined as from May 1 to August 31, 2016. The number of ED beds increased from 42 to 74 after the expansion. After adjusting individual characteristics and institutional characteristics, multivariate regression analysis was carried out to evaluate the effects of expansion on overall ED LOS. RESULTS: A total of 45,632 patients visited the emergency medical center: 20,592 patients before and 25,040 after the expansion. Although the absolute number of patients increased, the portion of medical patients, portion of non-referral patients, and ambulatory patients decreased during the study period (all p<0.001). Average visit number increased from 170.2 (standard deviation [SD], 27.3) to 203.6 (SD, 21.3) (p<0.001). The overall ED LOS increased from 332.2 (SD, 473.4) to 391.0 minutes (SD, 649.5). After adjusting for potential confounders, we found that ED expansion was associated with an increase in ED LOS by 75.8 minutes (95% confidence interval, 63.5 to 88.2). CONCLUSION: We found that the ED expansion was associated with a significant increase in ED LOS.
