A nationwide analysis of emergency medicine residents' CT interpretation in trauma: The Tract-EM study.

OBJECTIVE: To evaluate the accuracy and determine the factors influencing trauma CT interpretation proficiency among emergency medicine (EM) residents in Turkey through the TraCT-EM study (Interpretation of Trauma CT by EMergency Physicians). METHODS: This nationwide, multicenter, cross-sectional study was conducted in 29 academic emergency departments (EDs) from April 2023 to March 2024. A total of 401 senior EM residents participated in the study, each interpreting a standardized set of 42 trauma CT series (cranial, maxillofacial, and cervical) derived from seven patients. Interpretation accuracy was assessed, and factors predicting interpretation failure were analyzed using univariate and multivariate regression models. RESULTS: The median accuracy rate of residents was 64.9 %, with higher accuracy in normal CT findings. Using the Angoff method, 14 % of residents scored below the passing threshold. Factors associated with interpretation failure included shorter interpretation times (OR, 0.97; 95 % CI, 0.95-0.99), lower self-confidence in detecting serious pathologies (OR, 2.50; 95 % CI, 1.42-4.42), reliance on in-hospital radiology department reports (OR, 3.45; 95 % CI, 1.47-8.05), and receiving final radiology reports for CT scans (OR, 3.30; 95 % CI, 1.67-6.52), and lack of in-department training programs (OR, 2.51; 95 % CI, 1.34-4.70). CONCLUSION: The TraCT-EM study highlighted a 65 % accuracy rate for senior EM residents in trauma CT interpretation, with specific predictors of failure identified. These findings suggest a need for tailored radiology education strategies to enhance training and competency in trauma CT interpretation for EM residents. Further optimization of educational programs could address these gaps, ultimately improving patient outcomes in trauma care.

Does IV fentanyl, frequently used in emergency departments, change QTC value? A prospective observational study.

BACKGROUND: Fentanyl is an opioid analgesic frequently used in the emergency department (ED) and is usually administered without knowing the QTC values of the patients or being monitored. However, the effect of fentanyl on QTC, prolongation or shortening, has not been elucidated. This study aimed to determine the effect of fentanyl on QTC. METHODS: This is a prospective observational study in the ED of a tertiary hospital on patients who received intravenous fentanyl for procedures other than intubation. ECG was performed before and at 1, 5, 15, 30, and 60 min after the initiation of fentanyl administration, and QTC value was calculated. Primary outcomes were QTC prolongation, defined as an increase in the QTC to ≥ 500 ms or any increase in QTC by ≥ 60 ms. RESULTS: The study included 109 patients. Of these, 60 patients were male, and the median age was 40. Compared with the baseline QTC value, statistically significant prolongation was detected at the 5th, 15th, 30th, and 60th minutes, with the maximum prolongation at 30 min, and the median was 13.08 ms. Most patients with QTC prolongation were female and over 40 years of age. Clinically, none of these patients developed malignant arrhythmias during the 60-minute monitored observation period. CONCLUSION: Fentanyl prolonged the QTC value statistically significantly. Although no patient developed malignant arrhythmia clinically, our results suggest that this QTC-prolonging effect should be considered when using fentanyl in patients at risk of torsades.

Diagnostic accuracy of venous system ultrasound for subtypes of acute kidney injury.

BACKGROUND: Management of acute kidney injury (AKI) in the ED can be difficult due to uncertainty regarding the aetiology. This study investigated the diagnostic value of venous system ultrasound for determining the aetiological subtypes of AKI in the ED. METHODS: This multidisciplinary prospective cohort study was conducted in a single academic ED over the course of a year. Adult patients with AKI were evaluated using the venous excess ultrasound (VExUS) score, which is a four-step ultrasound protocol. The protocol begins with the inferior vena cava (IVC) measurement and examines organ flow patterns, including portal, hepatic and renal veins in the presence of dilated IVC. The AKI subtypes (hypovolaemia, cardiorenal, systemic vasodilatation and renal) were adjudicated by nephrologists and emergency physicians, considering data that became available during the hospitalisation. We determined the diagnostic test characteristics of VExUS for identifying each of the four AKI aetiological subtypes. RESULTS: 150 patients with AKI were included in the study. Hypovolaemia was the most frequent finally adjudicated cause of AKI (66%), followed by cardiorenal (18%), systemic vasodilatation (8.7%) and renal (7.3%). In diagnosing the cardiorenal subtype, the area under the curve (AUC) for VExUS grade >0 was 0.819, with 77.8% sensitivity and 80.5% specificity, and the AUC for IVC maximum diameter >20.4 mm was 0.865, with 74.1% sensitivity and 86.2% specificity. For the hypovolaemia subtype, the AUC for VExUS grade ≤0 was 0.711, with 83.8% sensitivity and 56.9% specificity, and the AUC for IVC maximum diameter ≤16.8 mm was 0.736, with 73.7% sensitivity and 68.6% specificity. None of the parameters achieved adequate test characteristics for renal and systemic vasodilatation subtypes. CONCLUSION: The VExUS score has good diagnostic accuracy for cardiorenal AKI and fair accuracy for hypovolaemic AKI but cannot identify renal and systemic vasodilatation subtypes. It should not therefore be used in isolation to determine the cause of AKI in the ED. TRIAL REGISTRATION NUMBER: NCT04948710.

Diagnostic Accuracy of Early Systolic Notching in Pulmonary Embolism.

OBJECTIVE: Recently, a cardiac sonography finding, early systolic notching (ESN), was reported with high sensitivity and specificity for the diagnosis of pulmonary embolism (PE) in a limited population. The aim of this study was to determine the diagnostic accuracy of ESN finding for PE in emergency department (ED) patients. METHOD: This prospective multicenter study was conducted in 4 academic EDs. All patients who underwent computed tomography angiography for suspected PE were included in the study. After inclusion, cardiac ultrasound including the right ventricular outflow tract Doppler signal was performed. The diagnostic tests of ESN finding were used for PE and its subgroups. RESULTS: In the study, 183 of 201 patients met the study criteria. Of all patients, 52.5% had PE (n = 96), and 19.7% (n = 36) had ESN finding. In all ED patients, the sensitivity of ESN for PE was 34% (95% CI 25-45), and the specificity was 97% (95% CI 90-99). In the subgroup analysis, the sensitivity of ESN for PE with high or intermediate-high risk was 69% (95% CI 49-85), and the specificity was 90% (95% CI 84-94). Inter-rater reliability for ESN finding between the cardiologist and emergency physician was strong with a kappa statistic of 0.87. CONCLUSION: The pulmonary Doppler flow of ESN was moderate to high specific but low sensitive for PE in all ED patients. In the subgroup analysis, this finding was moderate specific and low sensitive.

Pandemic hospitals and reorganizing emergency departments

Emergency departments have always been the first point of contact for hospitals in many situations, including man-made and natural disasters. The first places where patients with symptoms of COVID-19 were met in health institutions were also emergency departments. Emergency departments play an important role in diagnosing the disease and isolating patients (by hospitalization if necessary). The process, which starts with the triage of outpatients admitted to the emergency department and brought by ambulance, continues as isolation of the patients in appropriate areas including physical evaluation, management of laboratory and scanning processes and, if necessary, providing cardiopulmonary resuscitation with airway support. Afterwards, patients can be treated as an outpatient, or hospitalized, or treated at the intensive care unit in line with their preliminary diagnosis and clinical conditions. Disruptions that may occur in one or more of these stages can lead to crowds and lengthy queues in the emergency department by prolonging the follow-up period of the patients. One of the strengths of Turkey at this point is that emergency departments are accustomed to the heavy patient load. The experiences gained from these conditions have facilitated the organization of pre-hospital emergency medical services, pandemic hospitals, and their emergency departments. In this organization, the main goal should be to provide uninterrupted and high-quality patient care through personnel training, personal protection measures, and the creation of physical conditions. Turkey's emergency departments are accustomed to managing the intensive patient flow, as they work at full capacity during normal times. Thanks to the experiences of emergency healthcare workers, health service was provided without any patient being turned away from the door of the emergency departments during the COVID-19 pandemic. In this review, we aimed to present the organization of pandemic hospitals and emergency departments during the COVID-19 pandemic. We made a schematic representation of the architectural areas through the emergency department of Ankara City Hospital, which has a bed capacity of 4200 with 256 beds in emergency department.

The factors predicting pneumonia in COVID-19 patients: preliminary results from a university hospital in Turkey

Background/aim: Pneumonia is the most serious clinical presentation of COVID-19. This study aimed to determine the demographic, clinical, and laboratory findings that can properly predict COVID-19 pneumonia. Materials and methods: This study was conducted in the Gazi University hospital. All hospitalized patients with confirmed and suspected SARS-CoV-2 infection between 16 March 2020 and 30 April 2020 were analyzed retrospectively. COVID-19 patients were separated into two groups, pneumonia and nonpneumonia, and then compared to determine predicting factors for COVID-19 pneumonia. Variables that had a P-value of less than 0.20 and were not correlated with each other were included in the logistic regression model. Results: Of the 247 patients included in the study 58% were female, and the median age was 40. COVID-19 was confirmed in 70.9% of these patients. Among the confirmed COVID-19 cases, 21.4% had pneumonia. In the multivariate analysis male sex (P = 0.028), hypertension (P = 0.022), and shortness of breath on hospital admission (P = 0.025) were significant factors predicting COVID-19 pneumonia. Conclusion: Shortness of breath, male sex, and hypertension were significant for predicting COVID-19 pneumonia on admission. Patients with these factors should be evaluated more carefully for diagnostic procedures, such as thorax CT.

BLUE protocol ultrasonography in Emergency Department patients presenting with acute dyspnea.

OBJECTIVE: Dyspnea is a common Emergency Department (ED) symptom requiring prompt diagnosis and treatment. The bedside lung ultrasonography in emergency (BLUE) protocol is defined as a bedside diagnostic tool in intensive care units. The aim of this study was to investigate the test performance characteristics of the BLUE-protocol ultrasonography in ED patients presenting with acute dyspnea. METHOD: This study was performed as a prospective observational study at the ED of a tertiary care university hospital over a 3-month period. The BLUE-protocol was applied to all consecutive dyspneic patients admitted to the ED by 5 emergency physicians who were certified for advanced ultrasonography. In addition to the BLUE-protocol, the patients were also evaluated for pleural and pericardial effusion. RESULTS: A total of 383 patients were included in this study (mean age, 65.5 ±â€¯15.5 years, 183 (47.8%) female and 200 (52.2%) male). According to the BLUE-protocol algorithm, the sensitivities and specificities of the BLUE-protocol are, respectively, 87.6% and 96.2% for pulmonary edema, 85.7% and 99.0% for pneumonia, 98.2% and 67.3% for asthma/COPD, 46.2% and 100% for pulmonary embolism, and 71.4% and 100% for pneumothorax. Although not included in the BLUE-protocol algorithm, pleural or pericardial effusion was detected in 82 (21.4%) of the patients. CONCLUSION: The BLUE-protocol can be used confidently in acute dyspneic ED patients. For better diagnostic utility of the BLUE-protocol in EDs, it is recommended that the BLUE-protocol be modified for the assessment of pleural and pericardial effusion. Further diagnostic evaluations are needed in asthma/COPD groups in terms of the BLUE-protocol.

Evaluation of the general characteristics of patients aged 85 years and above admitted to a university hospital emergency department

Background/aim: The number of elderly people (≥65 years old) is increasing both in Turkey and internationally due to improved living conditions and decreased mortality rates. Knowing the characteristics of elderly patients admitted to emergency departments can provide guidance for diagnosis and treatment approaches. In this study, we analyzed the characteristics of very old patients (4≥85 years old) admitted to the emergency department and put together data for use in forward planning in healthcare services.Materials and methods: This retrospective study included all patients aged ≥85 years admitted to the Adult Emergency Department of Gazi University Medical Faculty Hospital between 01.01.2014 and 31.12.2014. Data concerning the patients' age, sex, date of admission, weekday or weekend admission, reason for admission, length of stay, number of readmissions, admission from within or outside the province, and whether they were hospitalized or not were evaluated.Results: In this study, 1105 admissions of 780 patients aged ≥85 years to the emergency department were analyzed. The median age of the patients was 87 years and 59% were female. The most frequent admissions were in January (11.4%). Most patients (63.1%) were admitted only once to our emergency department within the study period. A total of 40.5% of patients were hospitalized in the clinics or intensive care units. The rate of mortality at first admission was 1.5% (12 patients). The most common complaints at admission were infection (13.3%) and soft tissue traumas (crashes, sprains, fractures, dislocations) related to the musculoskeletal system (11.8%). Readmissions were more frequent in males. It was seen that male patients were more frequently admitted due to deterioration of general health status and genitourinary system symptoms, despite pain being more common among women.Conclusion: Due to the changing population structure, emergency staff in Turkey as well as internationally encounter old and very old patients more frequently. It is now imperative that emergency departments acquire the necessary infrastructure, human resources, knowledge, and equipment needed to meet the needs of these patients.

Effects of fast-track in a university emergency department through the National Emergency Department Overcrowding Study.

OBJECTIVE: To determine the impact of a fast track area on emergency department crowding and its efficacy for non-urgent patients. METHODS: The prospective cross-sectional study was conducted in an adult emergency department of a university-affiliated hospital in Turkey from September 17 to 30, 2010. Non-urgent patients were defined as those with Canadian Triage Acuity Scale category 4/5. The fast track area was open in the emergency department for one whole week, followed by another week in which fast track area was closed. Demographic information of patients, their complaints on admission, waiting times, length of stay and revisits were recorded. Overcrowding evaluation was performed via the National Emergency Department Overcrowding Study scale. In both weeks, the results of the patients were compared and the effects of fast track on the results were analysed. Continuous variables were compared via student's t test or Mann Whitney U test. Demographic features of the groups were evaluated by chi-square test. RESULTS: A total of 249 patients were seen during the fast track week, and 239 during the non-fast track week at the emergency department. Satisfaction level was higher in the fast track group than the non-fast track group (p < 0.001). The waiting times shortened from 20 minutes to 10 minutes and length of stay shortened from 80 minutes to 42 minutes during the fast track week. Morbidity and mortality rates remained unchanged. CONCLUSION: Owing to fast track, overcrowding in the emergency department was lessened. It also improved effectiveness and quality measures.

Wells score and Pulmonary Embolism Rule Out Criteria in preventing over investigation of pulmonary embolism in emergency departments.

INTRODUCTION: Unnecessary diagnostic tests are usually ordered to most of the patients with dyspnea or pleuritic chest pain, because of the worse outcomes of missed diagnosis of pulmonary embolism (PE). To identify rates and causes of over investigation for PE and to search whether it was possible to reduce this over investigation by using Wells score and Pulmonary Embolism Rule Out Criteria (PERC). MATERIALS AND METHODS: A retrospective observational cohort study performed in an emergency department of a tertiary care university hospital. All patients who were ordered diagnostic with the suspicion of PE were included in the study. They were grouped into two as PE (+) and PE (-) and compared. RESULTS: Among 108 patients, 53 (49%) were diagnosed as PE (+) and overdiagnosis was present in 55 (51%) patients i.e., PE (-). The sensitivity of high Wells score was 43%, specificity 78%, positive predictive value 66% and negative predictive value 59%. PERC criteria found to be negative (when all of the eight criteria were fulfilled) in only five patients. The sensitivity of the test was 98%, specificity 7%, positive predictive value 50%, negative predictive value 80%. When individual parameters of PERC were evaluated solely for the exclusion of PE; "no leg swelling" and "no previous deep venous thrombosis or PE history" were found significantly negatively correlated with PE diagnosis (p= 0.001, r= -0.325 and p= 0.013, r= -0.214 respectively). CONCLUSION: Over investigation of PE in emergency departments still remains as an important problem. In order to prevent this, the clinical prediction rules must be developed further and their use in combination should be searched in future studies.
