Objective: We investigated the effects of a quick Sequential Organ Failure Assessment (qSOFA)–negative result (qSOFA score <2 points) at triage on the compliance with sepsis bundles among patients with sepsis who presented to the emergency department (ED). Methods: Prospective sepsis registry data from 11 urban tertiary hospital EDs between October 2015 and April 2018 were retrospectively reviewed. Patients who met the Third International Consensus Definitions for Sepsis and Septic Shock criteria were included. Primary exposure was defined as a qSOFA score ≥2 points at ED triage. The primary outcome was defined as 3-hour bundle compliance, including lactate measurement, blood culture, broad-spectrum antibiotics administration, and 30 mL/kg crystalloid administration. Multivariate logistic regression analysis to predict 3-hour bundle compliance was performed. Results: Among the 2,250 patients enrolled in the registry, 2,087 fulfilled the sepsis criteria. Only 31.4% (656/2,087) of the sepsis patients had qSOFA scores ≥2 points at triage. Patients with qSOFA scores <2 points had lower lactate levels, lower SOFA scores, and a lower 28-day mortality rate. Rates of compliance with lactate measurement (adjusted odds ratio [aOR], 0.47; 95% confidence interval [CI], 0.29–0.75), antibiotics administration (aOR, 0.64; 95% CI, 0.52–0.78), and 30 mL/kg crystalloid administration (aOR, 0.62; 95% CI, 0.49–0.77) within 3 hours from triage were significantly lower in patients with qSOFA scores <2 points. However, the rate of compliance with blood culture within 3 hours from triage (aOR, 1.66; 95% CI, 1.33–2.08) was higher in patients with qSOFA scores <2 points. Conclusion A qSOFA-negative result at ED triage is associated with low compliance with lactate measurement, broad-spectrum antibiotics administration, and 30 mL/kg crystalloid administration within 3 hours in sepsis patients.

Purpose: Since 2012, acetaminophen can be accessed easily not only at pharmacies but also at convenience stores. The relationship between the easy access of acetaminophen and the risk of poisoning has been controversial. Several studies also reported different results regarding the risk of acetaminophen poisoning after access to acetaminophen was relaxed. This study examined the long-term effects on the risk of acetaminophen poisoning after easy access to acetaminophen was implemented. Methods: This was a retrospective analysis of an emergency department (ED)-based in-depth Injury Surveillance Cohort by the Korea Center for Disease Control and prevention from 2011 to 2018. Poisoning cases were selected from the Cohort, and the incidence of acetaminophen poisoning and the characteristics of the cases of acetaminophen poisoning were analyzed. The purchase path and the amount of ingestion in acetaminophen poisoning were sub-analyzed from data of six EDs. Results: Of 57,326 poisoning cases, 4.0% (2,272 cases) were acetaminophen poisoning. Of 2,272 cases of acetaminophen poisoning, 42.8% (974 cases) required in-patient care after ED management. Two hundred and sixty-four of these 964 cases required intensive care. The rates of cases that required in-patient treatment and the rates of cases that required intensive care increased from 29.4% in 2011 to 48.1% in 2018, and from 3.1% in 2011 to 15.2% in 2018, respectively (p<0.001, p<0.001). In the poisoning group with in-depth toxic surveillance (n=15,908), the incidence and proportion of acetaminophen (AAP) poisoning increased from 55 cases per year to 187 cases per year and 4.9% to 6.1%, respectively (p=0.009, p<0.001, respectively). The most common age group of acetaminophen poisoning was teenagers, which is different from the most common age group of other pharmaceutical agents: the middle age group of 40-49 years (p<0.001). Of 15,908 in-depth toxic surveillance patients, 693 patients had AAP poisoning, of whom 377 cases (54.2%) purchased acetaminophen from a non-pharmacy. The proportions of the purchase path from non-pharmacy were 41.4% at 2011-12 and 56.4% (2013-18) (p=0.004). The amount of acetaminophen ingestion was 13.5±14.3 g at 2011-12 and 13.9±15.1 g at 2013-18 (p=0.794). Conclusion Although the incidence of acetaminophen poisoning did not increase remarkably in the short term after the implementation of the new regulation, the incidence of acetaminophen poisoning has increased slightly during the study period of 2017-18. In addition, the proportion of the purchase path from non-pharmacies has increased since the emergence of new regulations for the easy access of acetaminophen in 2012. The incidence of acetaminophen poisoning might have been affected after the increasing accessibility of acetaminophen in convenience stores. Continuous control of acetaminophen poisoning is required. Furthermore, the prevention of acetaminophen poisoning should be focused on teenagers with specialized school education programs.

Objective: Emergency department (ED) overcrowding is a global trend that has negative impacts on the clinical outcomes, especially on critically ill patients. Reducing the portion of these critical patients by limiting the ED length of stay (LOS) to less than 6 hours has become one of the most crucial targets of government policy. This could be valuable for resolving overcrowding, but the clinical impacts and applicability had not been evaluated. Methods: Consecutive emergency patients registered on the National Emergency Department Information System from January 2016 to December 2017 were analyzed. This study included critically ill patients who had a severe illness code, as defined by the government. The in-hospital mortality rate was compared by under or over six hours of ED LOS, in patients with a severe illness code, and intensive care unit (ICU) patients. Results: Among 18,217,034 patients, 436,219 patients had a severe illness code. The ED LOS in the less than six hours group showed a higher in-hospital mortality rate than that of more than six-hours group (7.1% vs. 6.5%, respectively). When the rule for the severe illness code to ICU admission was changed, the in-hospital mortality rate showed a remarkable difference between the under and over six-hour group (12.8% vs. 15.0%, respectively). The proportion of critically ill patients admitted within six hours increased when the standard for outlier removal was set higher than the current. Conclusion A more suitable quality indicator or criterion for severe illness code is required for improving the clinical outcomes.

BACKGROUND/AIMS: This study aimed to investigate whether the apolipoprotein (Apo) B/ApoA-I ratio is associated with carotid intima-media thickness (CIMT) in type 2 diabetes mellitus (T2DM) subjects with low density lipoprotein cholesterol (LDL-C) levels less than 100 mg/dL. METHODS: This cross-sectional study included 845 subjects aged with T2DM 40 to 75 years who had visited Huh's Diabetes Center in Seoul, Republic of Korea for CIMT measurement. Traditional fasting lipid profiles, ApoB and ApoA-I levels were examined. CIMT was measured at three points on the far wall of 1 cm long section of the common carotid artery in the proximity of the carotid bulb. The mean value of six measurements from right and left carotid arteries were used as the mean CIMT. In this study, carotid atherosclerosis was defined as having a focal plaque or diffuse thickening of the carotid wall (mean CIMT ≥ 1.0 mm). RESULTS: The prevalence of carotid atherosclerosis increased with ApoB/ApoA-I ratio. The ApoB/ApoA-I ratio, expressed as both quartiles (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.21 to 3.79; p for trend = 0.014) and continuous values (OR, 10.05; 95% CI, 3.26 to 30.97; p < 0.001), was significantly associated with a higher risk for carotid atherosclerosis, regardless of conventional cardiovascular disease risk factors. The optimal ApoB/ApoA-I ratio cutoff value for detecting carotid atherosclerosis was 0.57, based on receiver operating characteristic curve analysis with a sensitivity of 58.0% and a specificity of 55.1%. CONCLUSIONS A high ApoB/ApoA-I ratio was significantly associated with carotid atherosclerosis in T2DM patients with LDL-C levels less than 100 mg/dL.

BACKGROUND: The clinical utility of ankle-brachial index (ABI) is not clear in subjects with less severe or calcified vessel. Therefore, we investigated the usefulness of color Doppler ultrasonography for diagnosing peripheral artery disease (PAD) in type 2 diabetes mellitus (T2DM) subjects. METHODS: We analyzed 324 T2DM patients who concurrently underwent ABI and carotid intima-media thickness (CIMT) measurements and color Doppler ultrasonography from 2003 to 2006. The degree of stenosis in patients with PAD was determined according to Jager's criteria, and PAD was defined as grade III (50% to 99% stenosis) or IV stenosis (100% stenosis) by color Doppler ultrasonography. Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the risk factors for PAD in patients with ABI 0.91 to 1.40. RESULTS: Among the 324 patients, 77 (23.8%) had ABI 0.91 to 1.40 but were diagnosed with PAD. Color Doppler ultrasonography demonstrated that suprapopliteal arterial stenosis, bilateral lesions, and multivessel involvement were less common in PAD patients with ABI 0.91 to 1.40 than in those with ABI ≤0.90. A multivariate logistic regression analysis demonstrated that older age, current smoking status, presence of leg symptoms, and high CIMT were significantly associated with the presence of PAD in patients with ABI 0.91 to 1.40 after adjusting for conventional risk factors. CIMT showed significant power in predicting the presence of PAD in patients with ABI 0.91 to 1.40. CONCLUSION: Color Doppler ultrasonography is a useful tool for the detection of PAD in T2DM patients with ABI 0.91 to 1.40 but a high CIMT.

PURPOSE: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. METHODS: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). RESULTS: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. CONCLUSION: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

PURPOSE: The Korean government has tried to decrease the suicide death rate over the last decade. Suicide attempts, particularly non-fatal attempts, are the most powerful known risk factor for a completed suicide. An analysis of suicide attempt methods will help establish the effective preventive action of suicide. Fit prevention according to the method of suicide attempt may decrease the incidence of suicide death. Self-poisoning is suggested as a major method of both suicide attempts and suicide death. The aim of this study was to determine if a self-poisoning patient is a suitable target for the prevention of the suicide. METHODS: This was retrospective analysis of a prospective cohort, which included patients who presented to the emergency department (ED) after a self-harm or suicide attempt from Jan 2013 to Dec 2017. The proportion of methods in suicide attempts, psychological consultation, and fatality according to the suicide attempt method were analyzed. The types of poison were also analyzed. RESULTS: Poisoning was the most common method of suicide attempts (52.1%). The rate of psychological consultations were 18.8% for all patients and 29.1% for poison patients (p < 0.001). The rate of mortality in poisoning was 0.6%. Psychological consultation was performed more frequently in admission cases than discharged cases. The most common materials of poisons was psychological medicines and sedatives that had been prescribed at clinics or hospital. CONCLUSION: Self-poisoning is a major method of suicide attempt with a high rate of psychiatric consultation, low mortality rate, versus others methods. The prevention of suicide death for suicide attempts may focus on self-poisoning, which is the major method of suicide attempts. A suitable aftercare program for self-poisoning may be an effective method for preventing suicide if an early diagnosis and management of psychiatric disorders through psychiatric consultation can be made, and early connection to social prevention program for non-fatal patients are possible.

PURPOSE: The aim of this study was to compare the toxicologic profiles and outcome of poisoned patients by comparing the data obtained through telephone counselling, each provided by emergency medical information center (1339) and emergency dispatch center (119). METHODS: We analyzed the telephone-based poison exposure data before and after Seoul 1339 merged to 119. We compared the Seoul 1339 call response data in 2008 with Seoul and Busan 119 call response data between 2014 and 2016. We analyzed the changes in the trend and quality of data obtained, as well as the quality of service provided by each center before and after this reallocation, by comparing the data each obtained through telephone counselling. RESULTS: The data was collected for a total of 2260 toxin exposure related calls made to Seoul 1339 in 2009, and 1657 calls to 119 in Seoul and Busan between 2014 and 2016. Significant difference was observed for age, sex, and reason for exposure to toxic substance between the two groups. CONCLUSION: After the integration of 1339 with 119, 119 focused on role of field dispatch and hospital transfer, lacking the consulting on drug poisoning. Moreover, data on exposure to toxic substances at the pre-hospital stage indicate that drug information and counseling are missing or unknown. In addition, first aid or follow-up instructions are not provided. Thus, systematic approach and management are required.
