Project description:BackgroundPediatric sedation in the emergency department (ED) is widely performed in Korea; thus exploring the trends of its use is necessary. This study aimed to investigate the characteristics of patients and sedatives use in the ED and verify their changes over recent years.MethodsA nationwide population-based retrospective study was conducted including pediatric patients aged ≤ 15 years who received sedative medication in the ED and were discharged during 2007-2018, using the Korean Health Insurance Review and Assessment Service database. Patient characteristics (age, sex, level of ED, and diagnosis) and type of sedative used were analyzed.ResultsSedation was performed in total 468,221 visits during 2007-2018 (399,320 visits, at least 3.8% of overall ED visits during 2009-2018). Among these, 71.0% were children aged 1-3 years and 93.5% were sedated to support diagnosis of injury. An increase in total sedation was observed in patients aged 4-6 years during the study period (from 13.8% to 21.8%). A gradual decrease in the use of chloral hydrate (CH) compared with an increase in ketamine use was observed (CH, from 70.6% to 28.6%; ketamine, from 23.8% to 60.7%). Therefore, ketamine was the most used sedative since 2014. The most frequently used sedatives over the study period differed according to age groups (CH in <1 year and 1-3 years; ketamine in 4-6 years and 7-10 years; and midazolam in 11-15 years).ConclusionsThe characteristics of patients related to sedatives use in the ED have changed over time. These changes should be considered in the development of future Korean guidelines regarding pediatric sedation in the ED.

Project description:ObjectivesCocaine use (CU) related chest pain (CP) is a common cause of emergency department (ED) visits in the United States. However, information on disposition and outcomes in these patients is scarce. We conducted a nationwide study to assess disposition from ED, hospitalization rates, in-hospital outcomes, and health care costs in patients with history of CU who presented to the ED with CP.MethodsWe queried the Nationwide Emergency Department Sample database from 2016-2018 for adult patients with CU presenting to the ED with CP. International Classification of Diseases, Tenth Revision codes were used to identify study patients.ResultsWe identified 149,372 patients. The majority were male (76%), presented to metropolitan centers (91.3%), and had a high prevalence of cardiovascular risk factors (48.1% with hypertension, 24.4% with coronary artery disease, 18.2% with diabetes) and psychiatric illnesses (21%). Overall, 21.4% of patients were hospitalized, 68.6% were discharged from ED and 6.6% left against medical advice. Patients requiring admission were older (51.8 vs 45.0; P < 0.0001) and had a higher prevalence of coronary artery disease, peripheral arterial disease, hypertension, diabetes, and chronic kidney disease. Of those admitted, 45.7% were diagnosed with myocardial infarction (MI), constituting 9.7% of the total study population. Over 80% of these patients underwent coronary angiography and 38.6% had coronary intervention. Mortality was 1.2%.ConclusionCU patients who present to ED are predominantly male, are from lower economic strata, and have significant comorbidity burden. One in 5 patients requires hospitalization and has more prevalent cardiovascular risk factors and comorbidities. In-hospital mortality is low, but incidence of MI and subsequent invasive procedures is high. CU may be considered a cardiac risk factor as it is associated with high rates of in-hospital MI.

Project description:Studies show that young children are vulnerable to burn injuries. We aimed to investigate the characteristics of thermal injuries in this population. We included children below 6 years of age who visited the emergency department (ED) after thermal injuries who were registered in the Korean Emergency Department-based Injury In-Depth Surveillance (2011-2016) database. Demographic characteristics, injury-related factors, and factors associated with ED treatment were gathered from the data. Then, we divided all children into two groups according to the ED discharge status: discharge versus admission (including cases transferred to other hospitals). The characteristics of the two groups were compared, and factors associated with admission were investigated. During the study period, 11,667 children with thermal injuries visited the ED. The number of boys was higher than the number of girls, and children aged 1 year accounted for the largest proportion. Most cases occurred in spring and indoors; the home was found to be the most common place. The most common type of burn was scald burns (69%), followed by contact burns (25.9%), and the most commonly burnt body area was the upper limbs (43.7%), followed by the lower limbs (16.8%). Most children (95.8%) were discharged home. The odds for hospital admission were lower for 2-3 and 4-5 year olds than for 0-1 year olds. The odds for hospital admission for contact burns were lower and those for electrical burns were higher than odds for hospital admission for scald burns. In summary, those aged 0-1 showed the largest incidence of thermal injuries and the most common burn mechanism was scald burns. Upper limbs were the most commonly affected body area, but their odds for requiring admission was lowest. Our results could be used as baseline data for prospective interventional studies investigating ways to reduce the incidence of childhood thermal injuries.

Project description:ObjectiveThis study aimed to examine trends in the incidence and outcomes of bicycle-related injuries in emergency departments (ED) in South Korea.MethodsWe analysed data from the National Emergency Department Information System database for adult patients (?20 years) with bicycle-related injuries presenting to EDs in South Korea between January 2012 and December 2014. Riders and bicycle passengers whose injuries were associated with bicycle use were included. Serious outcomes were defined as death at the ED, need for emergency operation, or intensive care unit admission.ResultsThe number of people who commute to work by bicycle increased by 36% from 205,100 in 2005 to 279,544 in 2015. Of 529,278 traffic-related trauma cases, 58,352 (11.0%) were bicycle-related, which increased from 7,894 (10.2%) in the first half of 2012 to 12,882 (12.2%) in the second half of 2014 (p < 0.001). However, the proportion of serious outcomes decreased from 5.0% to 4.2% during the study period (p < 0.001). Serious outcomes were most frequent in the elderly (65-74 years) and older elderly (?75 years) groups and decreased for all but the elderly age group from 10.3% to 9.8% (p = 0.204). The helmet use rate increased from 14.2% to 20.3% (p < 0.001) but was the lowest in the older elderly group (3.6%) without change during the study period (from 4.7% to 3.7%, p = 0.656). A lack of helmet use was significantly associated with serious outcomes (odds ratio, 1.811; 95% confidence interval, 1.576-2.082).ConclusionsAlthough the incidence of bicycle-related injuries increased, the proportion of serious outcomes decreased, possibly due to increased helmet use. Public education on safety equipment use is required, especially in elderly populations.

Project description:BackgroundThe use of topical antibiotics (TA) for prophylactic purposes after clean dermatologic procedures (CDP) is generally not recommended, and the prescription of TA needs to be individualized in consideration of each patient's situation and underlying disease. The aim of this study was to determine the proportion of patients who underwent CDP in outpatient settings and were prescribed TA inappropriately, as well as the factors that may affect the prescription of TA.MethodsOutpatient visits coded for CDP were selected using claims data from the Health Insurance Review and Assessment Service in 2018. Of these, patients receiving TA prescriptions were classified as having inappropriate TA use, and the proportion was estimated through technical analysis. A logistic regression analysis was used to identify factors influencing inappropriate prescriptions.ResultsData were analyzed using 423,651 visits, and TA was prescribed for approximately 1.9% of the visits. TA usage was higher among women (2.0%), 0-19 years of age (2.2%), medical aid (2.2%), clinic settings (2.4%), and metropolitan areas (2.0%). TA was prescribed more frequently in urology (8.6%), pediatrics (5.0%), and dermatology (4.2%) than in other specialties.ConclusionThe prescription rate of TA after CDP was 1.9% using the 1.4 million patient sample from the national health insurance claims data in Korea, which is equally weighted to represent 50 million people. Although the proportion of inappropriate TA prescriptions in Korea is lower than that in other nations, it cannot be overlooked because of the large number of cases. Efforts to improve quality are required to reduce the number of inappropriate prescriptions.

Project description:BACKGROUND:A national Helicopter Emergency Medical Service (HEMS) was introduced in Denmark in 2014 to ensure the availability of physician-led critical care for all patients regardless of location. Appropriate dispatch of HEMS is known to be complex, and resource utilisation is a highly relevant topic. Population-based studies on patient characteristics are fundamental when evaluating and optimising a system. The aim of this study was to describe the patient population treated by the Danish HEMS in terms of demographics, pre-hospital diagnostics, severity of illness or injury, and the critical care interventions performed. METHOD:The study is a retrospective nationwide population-based study based on data gathered from the Danish HEMS database. We included primary missions resulting in a patient encounter registered between October 1st 2014 and April 30th 2018. RESULTS:Of 13.391 dispatches registered in the study period we included 7133 (53%) primary missions with patient encounter: 4639 patients were air lifted to hospital, 174 patients were escorted to hospital by the HEMS physician in an ambulance, and in 2320 cases HEMS assisted the ground crew on scene but did not escort the patient to hospital. Patient age ranged from 0-99 years and 64% of the population were men. The median age was 60 years. The main diagnostic groups were cardio-vascular emergencies (41%), trauma (23%) and neurological emergencies (16%). In 61% of the cases, the patient was critically ill/injured corresponding to a NACA (National Advisory Committee for Aeronautics) score between 4 and 7 (both included). In more than one third of the missions a critical care intervention was performed. Ultrasound examination and endo-tracheal intubation were the critical care interventions most frequently performed (21% and 20%, respectively). CONCLUSION:The national Danish HEMS primarily attends severely ill or injured patients and often perform critical care interventions. In addition, the Danish HEMS provides rapid transport to highly specialised treatment for patients in the more rural parts of the country. Patients with cardio-vascular emergencies, trauma and neurological emergencies are among those patient groups most commonly seen. We conclude that the overall dispatch profile appears appropriate but emphasise that continuous development and refinement is essential.

Project description:Purpose:To evaluate the clinical characteristics and prognostic factors in patients with adrenocortical carcinoma (ACC) in South Korea. Methods:A nationwide, registry-based survey was conducted to identify pathologically proven ACC at 25 tertiary care centers in South Korea between 2000 and 2014. Cox proportional hazard model and log-rank test were adopted for survival analysis. Results:Two hundred four patients with ACC were identified, with a median follow-up duration of 20 months (IQR 5-52 months). The median age at diagnosis was 51.5 years (IQR 40-65.8 years), and ACC was prevalent in women (n = 110, 53.9%). Abdominal pain was the most common clinical symptom (n = 70, 40.2%), and ENSAT stage 2 was most common (n = 62, 30.4%) at the time of diagnosis. One hundred sixty-nine patients underwent operation, while 17 were treated with other modalities. The remission rate was 48%, and median recurrence-free survival time was 46 months. Estimated 5-year recurrence-free rate was 44.7%. There were more women, large tumor, atypical mitosis, venous invasion, and higher mitotic count in cancer recurrence group. Estimated 5-year overall survival and disease-specific survival rates were 64.5 and 70.6%, respectively. Higher ENSAT stage and advanced pathologic characteristics were risk factors for all-cause mortality of ACC. Large tumor size and cortisol-secreting tumor were additional risk factors for ACC-specific death. Conclusions:We report the first epidemiologic study regarding ACC in an Asian population. ENSAT stage 4; lymph node involvement; non-operative group; and invasion of vein, sinusoid, or capsule were associated with an increased risk for all-cause mortality.

Project description:OBJECTIVE:Rotavirus remains the main causative agent of gastroenteritis in young children in countries that have not yet introduced the vaccine. In Benin, rotavirus vaccine was introduced late December 2019 into the EPI. This study aims to provide pre-vaccination era rotavirus genotyping data in Benin. These data can supplement data from the surveillance system of Ministry of Health of Benin which is supported by the World Health Organization (WHO). RESULTS:Of the 420 diarrheal stool samples, actively collected in southern Benin from July 2016 through November 2018 from children under 5 years old and suffering from gastroenteritis, 167 (39.8%) samples were rotavirus EIA positive. 186 (44.3%) samples contained amplifiable rotavirus RNA detected by qRT-PCR method and were genotyped using one-step RT-PCR multiplex genotyping method. G1P[8] represents the predominant genotype (32%) followed by the G2P[4] (26%), G3P[6] (16%), G12P[8] (13%) and mixed G and P types (1%). Four samples (2%) could not be assigned both G and P type specificity.

Project description:OBJECTIVE:This study aims to provide basic data on the types and frequency of chemical ingestions and the clinical outcomes of chemical ingestion injury. METHODS:This study retrospectively analyzed the data obtained from the Emergency Department-Based Injury In-depth Surveillance of the Korea Centers for Disease Control and Prevention (South Korea) from 2011 to 2016. Patients ingesting chemicals aged ? 18 years were included, but those ingesting unknown chemical substances or with unknown clinical outcomes were excluded. RESULTS:This study included 2,712 (47.2% were men and 52.8% were women, mean age, 47.05 years) patients ingesting chemicals. Unintentional and intentional ingestions were reported in 1,673 (61.7%) and 1,039 (38.3%), respectively. The most commonly ingested chemical substances were hypochlorites, detergents, ethanol, and acetic acid. In the unintentional ingestion group, the most common chemicals upon admission were hypochlorites (74), glacial acetic acid (60), and detergent (33). The admission rates were 60% for glacial acetic acid, 58.3% ethylene glycol, and 30.4% other alkali agents. In the intentional ingestion group, the most common chemicals upon admission were hypochlorites (242), glacial acetic acid (79), ethylene glycol (42), and detergent (41). The admission rates were 91.9% for glacial acetic acid, 87.5% ethylene glycol, 85.7% potassium cyanide, and 81.4% hydrochloric acid. In total, 79 deaths (10 unintentional ingestions, 69 intentional ingestion) were reported, and glacial acetic acid had an odds ratio of 9.299 for mortality. CONCLUSION:We compared the intentional and unintentional ingestion groups, and analyzed the factors affecting hospital admission and mortality in each group. The types and clinical outcomes of chemical ingestion varied depending on the purpose of chemical ingestion. The findings are considered beneficial in establishing treatment policies for patients ingesting chemicals.

Project description:BackgroundAlthough Korea ranks first in the suicide rate of elderly individuals, there is limited research on those who attempt suicide, with preventive measures largely based on population-based studies. We compared the demographic and clinical characteristics of elderly individuals who attempted suicide with those of younger adults who visited the emergency department after suicide attempts and identified the factors associated with lethality in the former group.MethodsIndividuals who visited the emergency department after a suicide attempt from April 1, 2017, to January 31, 2020, were included. Participants were classified into two groups according to age (elderly, ≥65 years; adult, 18-64 years). Among the 779 adult patients, 123 were elderly. We conducted a chi-square test to compare the demographic and clinical features between these groups and a logistic regression analysis to identify the risk factors for lethality in the elderly group.ResultsMost elderly participants were men, with no prior psychiatric history or suicide attempts, and had a higher prevalence of underlying medical conditions and attributed their attempts to physical illnesses. Being sober and planning suicide occurred more frequently in this group. In the elderly group, factors that increased the mortality rate were biological male sex (p<0.05), being accompanied by family members (p<0.05), and poisoning as a suicide method (p<0.01).ConclusionSuicide attempts in elderly individuals have different characteristics from those in younger adults and are associated with physical illness. Suicides in the former group are unpredictable, deliberate, and fatal. Therefore, tailored prevention and intervention strategies addressing the characteristics of those who are elderly and attempt suicide are required.
