Comparison of Bedside Index for Severity in Acute Pancreatitis and Emergency Department SpO2, Age and Systemic Inflammatory Response Syndrome Scores in Predicting Severe Acute Pancreatitis in Patients with Acute Pancreatitis in the Emergency Department.

BACKGROUND: As the mortality of severe acute pancreatitis (SAP) is significantly higher than those with mild or moderate severity, it is of clinical significance to identify patients most likely to develop SAP at the time of emergency department (ED) presentation. OBJECTIVES: The aim of this study was to compare the performance of the Bedside Index for Severity in Acute Pancreatitis (BISAP) and the Emergency Department SpO2, Age and SIRS (ED-SAS) scoring systems as early risk assessment tools for identifying patients at high-risk of developing SAP. METHODS: We retrospectively reviewed adult patients with AP presented to ED between January 2019-September 2022. We calculated the scores of each patient with the parameters of the initial data. The primary outcome was SAP. The secondary outcomes were 30-day mortality, intensive care admission, and identifying low-risk patients without complications. RESULTS: Of 415 patients, 34 (8.2%) developed SAP and 15 (3.6%) died. With regard to predicting SAP, BISAP and ED-SAS scores had similar discriminative ability with area under the curves (AUCs) of 0.84 (95% confidence interval [CI]:0.80-0.88) and 0.83 (95% CI:0.79-0.86), respectively (p = 0.642). At a cut-off score of ≥2 for SAP, sensitivity/specificity values were 73.5%/82.4% for BISAP, 76.5%/83.2% for ED-SAS. BISAP and ED-SAS scores of ≥3, yielded sensitivity/specificity values of 50%/95.8% and 35.3%/95.5%, respectively. BISAP and ED-SAS were also similar in predicting mortality (AUCs of 0.92 vs. 0.90, respectively) and intensive care unit admission (AUCs 0.91 vs. 0.91). CONCLUSION: The BISAP and ED-SAS scores performed similarly in predicting SAP, mortality, and intensive care unit admission. As an easily calculated tool early in the ED, ED-SAS may be helpful in disposition decisions for emergency physicians.

Prognostic value of early warning scores in patients presenting to the emergency department with exacerbation of COPD.

OBJECTIVE: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a condition that frequently presents to the emergency department (ED) and its prognosis is not very well understood. Risk tools that can be used rapidly in the ED are needed to predict the prognosis of these patients. METHODS: This study comprised a retrospective cohort of AECOPD patients presenting to a single center between 2015 and 2022. The prognostic accuracy of several clinical early warning scoring systems, Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), NEWS­2, Systemic Inflammatory Response Syndrome (SIRS) and the quick Sepsis-related Organ Failure Assessment (qSOFA), were compared. The outcome variable was determined as one-month mortality. RESULTS: Of the 598 patients, 63 (10.5%) had died within 1 month after presenting to the ED. Patients who died had more often congestive heart failure, altered mental status, and admission to intensive care, and they were older. Although the MEWS, NEWS, NEWS­2, and qSOFA scores of those who died were higher than those who survived, there was no difference between the SIRS scores of these two groups. The score with the highest positive likelihood ratio for mortality estimation was qSOFA (8.5, 95% confidence interval [CI] 3.7-19.6). The negative likelihood ratios of the scores were similar, the NEWS score had a negative likelihood ratio of 0.4 (95% CI 0.2-0.8) with the highest negative predictive value of 96.0%. CONCLUSION: In AECOPD patients, most of the early warning scores that are frequently used in the ED were found to have a moderate ability to exclude mortality and a low ability to predict mortality.

Adherence to Clinical Practice Guidelines for Non-ST Elevation Acute Coronary Syndrome in the Emergency Department: Exploring the Role of Social, Healthcare-system, and Clinical Determinants.

OBJECTIVES: The aim of this study was to assess adherence to the European Society of Cardiology 2020 non-ST elevation acute coronary syndrome (NST-ACS) guidelines, identify factors affecting this compliance, and explore the link between adherence and adverse cardiac outcomes. METHODS: This prospective cohort study was conducted in a tertiary-level academic hospital between January 2022 and January 2023. Patients diagnosed with NST-ACS in the emergency department (ED) were included. The primary outcome measured was the rate of adherence to the guidelines, and secondary outcomes were factors affecting this adherence in the ED and its association with 28-day adverse cardiac outcomes. RESULTS: Of the 298 patients included, guideline adherence was achieved in 32.2% in the ED. The highest compliance was observed in performing a 12-lead electrocardiogram (ECG) within 10 minutes (99.7%), while the lowest was found for obtaining additional right and posterior ECG leads when ongoing ischemia was suspected (42.3%). Factors associated with better adherence included the experience level of the treating physician, the presence of cardiac-quality chest pain, initial ischemic ECG findings, higher initial troponin levels, and advanced history, electrocardiogram, age, risk factors, and troponin score and Charlson comorbidity index. Complete guideline adherence over 28 days was achieved in 19.1% of patients and was found to be significantly associated with lower rates of adverse cardiac outcomes. CONCLUSIONS: Adherence to NST-ACS guidelines was generally low but was associated with improved patient outcomes. This study highlighted the importance of various factors associated with guideline adherence. Future research should explore further barriers to guideline adherence and develop targeted interventions.

Elderly-onset pulmonary sarcoidosis: A radiological approach to diagnosis.

BACKGROUND AND AIM: The aim was to compare the radiological and clinical characteristics of sarcoidosis between elderly and non-elderly patients. METHODS: This retrospective observational study was carried out in patients with sarcoidosis. Elderly-onset sarcoidosis was defined as sarcoidosis diagnosed in patients ≥65 years-old. Patients were stratified by age (≥65 years versus <65 years) and radiological and clinical data were compared between age groups. RESULTS: Of the 163 patients, 38 (23.3%) were in the elderly group and 125 (76.7%) were in the non-elderly group. Elderly patients more frequently demonstrated arthralgia (50% vs. 12.8%, p<0.001), coronary artery disease  (15.8% vs. 2.4%, p=0.005), congestive heart failure (13.2% vs. 0.8%, p=0.003), pneumonia (7.9% vs. 0.8%, p=0.04), and pleural fluid (18.4% vs. 0.0%, p<0.001). Clinical remission was significantly more likely in younger patients than in the elderly (76.8% vs. 55.3%, p=0.01). The clinical course to chronic-progressive disease was similar in both groups (p=0.635). Radiologically, lymph nodes measuring 10-25 mm in the short axis (89.5% vs. 72.6%, p=0.032), usual interstitial pneumonia pattern (10.5% vs. 0.8%, p=0.011), and main pulmonary artery diameter above 30 mm (34.2% vs. 16.0%, p=0.014) were significantly more frequent in the elderly group. Elderly patients tended to demonstrate Scadding stage I and II sarcoidosis (39.5% and 31.6%). CONCLUSIONS: Presentation of elderly-onset sarcoidosis appears to differ from young-onset sarcoidosis. Radiologically, lymph node enlargement and the pattern of fibrosis may be distinctive.

Impact of COVID-19 pneumonia on interstitial lung disease: semi-quantitative evaluation with computed tomography.

OBJECTIVES: To evaluate the CT scores and fibrotic pattern changes in interstitial lung disease (ILD) patients, with and without previous COVID-19 pneumonia. METHODS: Patients with ILD (idiopathic pulmonary fibrosis (IPF) and connective tissue disease-associated ILD (CTD-ILD)) were retrospectively enrolled in the study which consisted of patients who had COVID-19 pneumonia while the control group had not. All patients had two CT scans, initial and follow-up, which were evaluated semi-quantitatively for severity, extent, and total CT scores, fibrosis patterns, and traction bronchiectasis. RESULTS: A total of 102 patients (pneumonia group n = 48; control group n = 54) were enrolled in the study. For both groups, baseline characteristics were similar and CT scores were increased. While there was a 4.5 ± 4.6 point change in the total CT score of the COVID-19 group, there was a 1.2 ± 2.7 point change in the control group (p < 0.001). In the IPF subgroup, the change in total CT score was 7.0 points (95% CI: 4.1 to 9.9) in the COVID-19 group and 2.1 points (95% CI: 0.8 to 3.4) in the control group. Seven patients (14.6%) in the COVID-19 group progressed to a higher fibrosis pattern, but none in the control group. CONCLUSIONS: Semi-quantitative chest CT scores in ILD patients demonstrated a significant increase after having COVID-19 pneumonia compared to ILD patients who had not had COVID-19 pneumonia. The increase in CT scores was more prominent in the IPF subgroup. There was also a worsening in the fibrosis pattern in the COVID-19 group. KEY POINTS: • The impact of COVID-19 pneumonia on existing interstitial lung diseases and fibrosis is unclear. • COVID-19 pneumonia may worsen existing interstitial lung involvement with direct lung damage and indirect inflammatory effect. • COVID-19 pneumonia may affect existing lung fibrosis by triggering inflammatory pathways.

Relationship between clinical anxiety and patient outcomes in patients with chronic obstructive lung disease exacerbation in the emergency department.

PURPOSE: Anxiety is a comorbidity that is not routinely addressed in patients with chronic obstructive lung disease (COPD) exacerbation in the emergency department (ED). Anxiety in patients with COPD exacerbation can be related with negative outcomes. The Generalized Anxiety Disorder 7 (GAD-7) score is an easy-to-use tool to determine anxiety. This study aimed to investigate the relationship between GAD­7 score and patient outcomes in patients with COPD exacerbation in the ED. METHODS: A prospective, cross-sectional study was conducted in a tertiary academic ED between July 2019 and January 2021. Patients admitted to the ED with COPD exacerbation were included. A GAD­7 score of ≥ 10 was defined as clinically significant anxiety. Negative outcomes were defined as a composite outcome that included recurrent ED visits, intensive care unit admission, and mortality. The relationship between clinically significant anxiety and negative outcomes within 30 days was determined. RESULTS: A total of 92 patients were assessed for eligibility and 80 were included in the study. Thirty-seven patients (46.3%) experienced negative outcomes. Although no significant difference was detected in median GAD­7 scores between patients with positive and negative outcomes, negative outcomes were significantly higher in patients who had a GAD­7 score of ≥ 10 (n = 25, p = 0.03). A sensitivity of 43.2%, specificity of 79.1%, positive likelihood ratio of 2.1 and negative likelihood ratio of 0.7 were determined for GAD­7 score in predicting negative outcome. CONCLUSION: In patients with COPD exacerbation in the ED, a GAD­7 score of ≥ 10 was associated with 30-day negative outcomes.

Comparison of PECARN clinical decision rule and clinician suspicion in predicting intra-abdominal injury in children with blunt torso trauma in the emergency department.

BACKGROUND: The Pediatric Emergency Care Applied Research Network (PECARN) developed a clinical decision rule to identify children at low risk for intra-abdominal injury requiring acute intervention (IAI-I) for reducing unnecessary radiation exposure of ab-dominal computed tomography (CT) after blunt torso trauma. This study aimed to compare the PECARN decision rule with clinician suspicion in identifying children at low risk of intra-abdominal injuries that an abdominal CT scan can be safely avoided. METHODS: This study is a retrospective review of children with blunt torso trauma in an academic emergency department (ED) between 2011 and 2019. Patients were considered positive for the PECARN rule if they exhibited any of the variables. Clinician suspi-cion was defined as actual CT ordering of the treating physician. The primary outcome was IAI-I detected by imaging or surgery within 1 month after the trauma, and the secondary outcome was any intra-abdominal injury (IAI) presence. RESULTS: Among the 768 children included, 48 (6.25%) had intra-abdominal injuries and 21 (2.73%) of whom underwent acute in-tervention. Four hundred and fifty-three (59%) children underwent abdominal CT scanning. If the PECARN rule had been applied, 232 patients would have undergone abdominal CT. The rule revealed 90.48% (95% CI=68.17-98.33%) sensitivity for IAI-I and 81.25% (95% CI=66.9-90.56%) for IAI. Clinician suspicion revealed sensitivities of 100% (95% CI=80.76-00%) and 93.75% (95% CI=81.79-98.37%) for IAI-I and IAI, respectively. Sensitivities of the rule and clinician suspicion were statistically similar for both IAI-I (p=0.5) and IAI (p=0.146). CONCLUSION: In this study, the PECARN abdominal rule and clinician suspicion performed similarly in identifying intra-abdominal injuries in children with blunt torso trauma. However, our study supports the use of PECARN abdominal rule in addition to clinical judgment to limit unnecessary abdominal CT use in pediatric patients with blunt torso trauma in the ED.

Performance of qSOFA, SIRS, and the qSOFA + SIRS combinations for predicting 30-day adverse outcomes in patients with suspected infection.

BACKGROUND: The use of the quick sequential organ failure assessment score (qSOFA) score and systemic inflammatory response syndrome (SIRS) criteria to identify patients at high risk for adverse outcomes in the emergency department (ED) remains controversial due to their low predictive performance and lack of supporting evidence. This study aimed to determine the predictive performance of qSOFA, SIRS, and the qSOFA + SIRS combinations for adverse outcomes. METHODS: All adult patients admitted to the ED with suspected infection were prospectively included. qSOFA scores ≥ 2, SIRS score ≥ 2 were defined as risk-positive for adverse outcome. Furthermore, combination­1, which was defined as either qSOFA or SIRS positivity, and combination­2, which was defined as both qSOFA and SIRS positivity, were also considered as risk-positive for adverse outcome. The predictive performance of qSOFA, SIRS, combination­1, and combination­2 for a composite adverse outcome within 30 days, including mortality, intensive care unit (ICU) admission, and non-ICU hospitalization, were determined. RESULTS: A total of 350 patients were included in the analysis. The composite outcome occurred in 211 (60.3%) patients within 30 days: mortality in 84 (24%), ICU admission in 78 (22.3%), and non-ICU hospitalization in 154 (44%). The sensitivity and specificity, respectively, were determined in predicting composite outcome as 0.34 and 0.93 for qSOFA, 0.81 and 0.31 for SIRS, 0.84 and 0.28 for combination­1, and 0.31 and 0.96 for combination­2. CONCLUSION: The study results suggest that qSOFA and combination­2 could be a useful tool for confirming patients at high risk for adverse outcomes. Although SIRS and combination­1 could be helpful for excluding high-risk patients, the requirement of white blood cell counts limits their utilization for screening.

Predictors of prolonged hospitalization in patients with mild and moderate pancreatitis presenting to the emergency department.

BACKGROUND: Patients with acute pancreatitis often present to the emergency department (ED) and usually require hospital admission. The aim of this study was to determine predictors of prolonged hospital stays in patients with mild forms of acute pancreatitis. METHODS: This retrospective cohort study was conducted in patients diagnosed in the ED with mild and moderate acute pancreatitis according to the revised Atlanta classification. Patients with available data between 2007 and 2017 were included and were divided based on their admission duration. Eight days or more was considered a long hospitalization. A multivariate logistic regression model was constructed to determine the independent predictors of prolonged hospital stays. RESULTS: Of the 485 evaluated patients, 335 were included in the analysis. Baseline characteristics, determined by vital signs and laboratory parameters, were similar between the short and long hospitalization groups. However, the long hospitalization group received more intravenous crystalloid in the ED, and this group used more diuretics and more angiotensin-converting enzyme inhibitor and angiotensin-receptor blocker (ACEI/ARB) drugs than the other group. Diuretic use was present in 8 patients (4.8%) in the short hospital length of stay group and in 26 patients (15.3%) in the long hospital length of stay group. Age, gender, ACEI/ARB use, diuretic use, total amount of intravenous crystalloid administered in the ED, aPTT, BUN, creatinine, and presence of biliary pathology were included in the multivariate analysis. Regarding the final analysis, diuretic use was an independent predictor of prolonged hospitalization (odds ratio 2.89, 95% confidence interval 1.05-8.00, p = 0.041). CONCLUSION: Diuretic use is an independent predictor of long hospitalization in patients with mild and moderate pancreatitis. Drugs affecting total volume balance may prolong hospital stays in these patients.

2021 Guideline for the Management of COPD Exacerbations: Emergency Medicine Association of Turkey (EMAT) / Turkish Thoracic Society (TTS) Clinical Practice Guideline Task Force.

Chronic obstructive pulmonary disease (COPD) is an important public health problem that manifests with exacerbations and causes serious mortality and morbidity in both developed and developing countries. COPD exacerbations usually present to emergency departments, where these patients are diagnosed and treated. Therefore, the Emergency Medicine Association of Turkey and the Turkish Thoracic Society jointly wanted to implement a guideline that evaluates the management of COPD exacerbations according to the current literature and provides evidence-based recommendations. In the management of COPD exacerbations, we aim to support the decision-making process of clinicians dealing with these patients in the emergency setting.

Use of noninvasive volume assessment methods to predict acute blood loss in spontaneously breathing volunteers.

OBJECTIVE: The use of noninvasive volume assessment methods to predict acute blood loss in spontaneously breathing patients remains unclear. We aimed to investigate changes in the pleth variability index (PVI), vena cava collapsibility index (VCCI), end-tidal carbon dioxide (EtCO2), pulse pressure (PP), and mean arterial pressure (MAP) in spontaneously breathing volunteers after acute loss of 450 mL blood and passive leg raise (PLR). METHODS: This prospective observational study enrolled healthy volunteers in the blood donation center of an academic hospital. We measured the PVI, EtCO2, VCCI, MAP, and PP before blood donation; at the 0th and 10th minute of blood donation; and after PLR. The primary outcome was the changes in PVI, EtCO2, VCCI, MAP, and PP. RESULTS: We enrolled thirty volunteers. There were significant differences among the four obtained measurements of the PVI, EtCO2, and MAP (P<0.001, P<0.001, P<0.001, respectively). Compared to the predonation values, post-hoc analysis revealed an increase in the PVI at the 0th min postdonation (mean difference [MD], 5.4±5.9; 95% confidence interval [CI], -7.6 to -3.1; P<0.001); a decrease in the EtCO2 and MAP at the 0th and 10th minute postdonation, respectively (MD, 2.4±4.6; 95% CI, 0.019 to 4.84; P=0.008 and MD, 6.4±6.4; 95% CI, 3 to 9.7; P<0.001, respectively). Compared with EtCO2 at the 10th minute, the value increased after PLR (MD, 1.8±3.2; 95% CI, 0.074 to 4.44; P=0.006). CONCLUSION: The PVI and EtCO2 could detect early hemodynamic changes after acute blood loss. However, it remains unclear whether they can determine volume status in spontaneously breathing patients.

Clinical characteristics of neutrophilic, eosinophilic and mixed-type exacerbation phenotypes of COPD.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) comprises a significant number of emergency department (ED) presentations, and hematological phenotypes may have prognostic significance. The aim of this study was to investigate the effect of hematological phenotypes on serious outcomes in COPD exacerbations. METHODS: A prospective cohort study was carried out in patients with COPD exacerbation presenting to the ED. The patients were classified into three groups, including neutrophilic, eosinophilic, and mixed-type (including neutrophilic and eosinophilic features) COPD exacerbation. Outcome measures were defined as mortality, hospitalization, and need for intensive care unit (ICU) care within three months, and these outcomes were compared among groups. RESULTS: A total of 173 COPD patients were assessed for eligibility, and 147 of them were included in the final analysis. The study population consisted of 90 patients with neutrophilic exacerbation (61.2%), 26 patients with eosinophilic exacerbation (17.7%), and 31 patients with mixed-type exacerbation (21.1%). The neutrophilic exacerbation group was older, was more often tachycardic and desaturated, and had more sputum production compared with the eosinophilic exacerbation group. Mortality was seen in 35 patients in the neutrophilic exacerbation group (38.9%), whereas 5 patients in the eosinophilic group (19.2%) and 6 patients in the mixed-type group (19.4%) died (p = .044). No difference was observed among groups in terms of hospital and ICU admission. CONCLUSION: COPD exacerbations with neutrophilic phenotypes presented to the ED with more serious clinical findings compared with eosinophilic exacerbations. This may also have a possible effect on mortality.

Reliability of chest pain risk scores in cancer patients with suspected acute coronary syndrome.

OBJECTIVE: The history, electrocardiogram, age, risk factors, troponin (HEART), the thrombolysis in myocardial infarction (TIMI), and Global Registry of Acute Coronary Events (GRACE) scores are useful risk stratification tools in the emergency department (ED). However, the accuracy of these scores in the cancer population is not well known. This study aimed to compare the performance of cardiac risk stratification scores in cancer patients with suspected acute coronary syndrome (ACS) in the ED. METHODS: This prospective cohort study recruited patients with cancer who visited the ED because of suspected ACS. The development of any major adverse cardiac events (MACE) within 6 weeks was recorded, with the study outcome being a MACE within 6 weeks of ED admission. RESULTS: A total of 178 patients participated in this study, of whom 5.6% developed a MACE. Statistically significant differences were found between the mean HEART and TIMI scores in predicting MACE. The HEART score had the highest area under the curve (0.64; 95% confidence interval, 0.48-0.81), highest sensitivity (80%), and highest negative predictive value (97.5) in patients with cancer. CONCLUSION: We found a similar rate of MACE in cancer patients with low-risk chest pain compared to that in the general population. However, the HEART, TIMI, and GRACE scores had a lower performance in cancer patients with MACE compared to that in the general population.

A randomized controlled trial of the effects of local tranexamic acid on mortality, rebleeding, and recurrent endoscopy need in patients with upper gastrointestinal hemorrhage.

OBJECTIVE: Tranexamic acid (TXA) is an antifibrinolytic agent used to control bleeding in different circumstances. We conducted a randomized controlled trial to assess the efficacy and safety of locally administered TXA in upper gastrointestinal hemorrhage. METHODS: This single-center, double-blind, randomized controlled trial was performed in a tertiary emergency department (ED) in patients presenting with upper gastrointestinal bleeding symptoms between 2016 and 2018. The patients received either 2000 mg of 5% TXA in 100 mL of isotonic saline solution or 100 mL isotonic saline (control group) via the nasogastric route. As a composite outcome, recurrent endoscopy need, rebleeding, surgery need, recurrent admission to the ED, and mortality parameters were evaluated at the end of a one-month period. RESULTS: During the study period, 78 patients were randomized into the TXA group, and 79 patients were randomized into the isotonic saline group. The majority of the bleedings (61%) were in Forrest class 3, and the most frequent cause was peptic ulcer disease. The composite outcome occurred in 25 of the TXA patients (32.1%) and 23 of the isotonic saline patients (29.1%); no statistically significant difference was found between the groups (P = 0.690). In addition, no statistically significant differences were observed between the TXA and control groups regarding mortality (10.3 vs 12.7%; P = 0.637), recurrent ED admission (17.9 vs 12.7%; P = 0.357), or thromboembolic complications (3.8 vs 1.3%; P = 0.367). CONCLUSION: Locally administered TXA confers no additional benefit over standard care in patients with upper gastrointestinal hemorrhage.

Role of Electrocardiographic Manifestations in Admission Decision in Patients with Chronic Obstructive Pulmonary Disease Exacerbation.

OBJECTIVE: To determine the ECG manifestations of COPD exacerbations and their roles in the decision making process in admission. STUDY DESIGN: A descriptive cross-sectional study. PLACE AND DURATION OF STUDY: Emergency Department (ED) of Kocaeli University, Turkey, from November 2016 to December 2017. METHODOLOGY: All COPD patients who presented with exacerbation symptoms and agreed to participate in the study were enrolled, and the exacerbation characteristics were recorded in the standardised charts. Patients were excluded if they refused to participate in the study, if they presented repetitively to the ED with the same presentation, and if the ECG strip at the presentation could not be obtained. A binary logistic regression model was constructed to assess the factors predicting hospital admission, including the ECG features. RESULTS: A total of 146 patients were included in the final analysis. Upon presentation, 122 patients (83.6%) exhibited sinus rhythm, 21 exhibited atrial fibrillation (14.4%), and 3 of them were multifocal atrial tachycardia and junctional rhythm. Thirty-four admitted patients (41.0%) and 22 of the discharged patients (34.9%) exhibited ST and T wave changes in their ECGs (p=0.457). No statistically significant differences were found regarding the rhythms, axes, P wave characteristics, PR interval durations, QRS interval durations, corrected QT(QTc) durations, and bundle branch block occurrences between the admitted and discharged patients. Although the QTc dispersion was more prominent in the admitted group in the univariate analysis (p=0.035), the multivariate analysis revealed that only hypoxemia, older age, increased dyspnea scores, and sputum purulence were independent predictors of hospital admission. CONCLUSION: None of the ECG findings were determined to be successful in predicting the admission needs in COPD exacerbations.
