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.

The diagnostic value of laboratory tests in detecting solid organ injuries in pediatric patients with blunt abdominal trauma.

BACKGROUND: Computed tomography of the abdomen (CT) is used as the gold standard for detecting solid organ injuries (SOI) after blunt abdominal trauma (BAT). However, patient selection for CT is still controversial due to its potential risks. In this study, we aimed to investigate the usefulness of laboratory tests in the detection or exclusion of SOI in pediatric patients evaluated in the emergency department due to BAT. METHODS: The study was planned as a prospective, observational study and was conducted in the emergency department of a university hospital between February 2018 and February 2019. Patients under the age of 18 who were evaluated for BAT in the emergency department were included in the study. In the study, the diagnostic value of abnormal laboratory tests in detecting SOI was calculated by accepting CT results as the gold standard. RESULTS: Of the 323 patients included in the study, 118 (36%) were male. There were 283 patients who underwent CT. SOI was detected in 18 (6%) patients. Abnormal alanine aminotransferase, aspartate aminotransferase, amylase and lipase tests were found to be statistically significant in predicting SOI (p < 0.05). However, none of the tests were found to have sufficient sensitivity and specificity. Hemoglobin, hematocrit, lactate and base excess values were not found to be statistically significant in predicting SOI (p > 0.005). CONCLUSIONS: The hematologic laboratory tests are insufficient to rule out solid organ injury in pediatric patient with BAT.

Comparison of manual and mechanical chest compression techniques using cerebral oximetry in witnessed cardiac arrests at the emergency department: A prospective, randomized clinical study.

AIM: We aimed to compare regional cerebral oxygen saturation (rSO2) levels during cardiopulmonary resuscitation (CPR), performed either manually or using a mechanical chest compression device (MCCD), in witnessed cardiac arrest cases in the emergency department (ED), and to evaluate the effects of both the CPR methods and perfusion levels on patient survival and neurological outcomes. METHODS: This single-center, randomized study recruited patients aged ≥18 years who had witnessed a cardiopulmonary arrest in the ED. According to the relevant guidelines, CPR was performed either manually or using an MCCD. Simultaneously, rSO2 levels were continually measured with near-infrared spectroscopy. RESULTS: Seventy-five cases were randomly distributed between the MCCD (n = 40) and manual CPR (n = 35) groups. No significant difference in mean rSO2 levels was found between the MCCD and manual CPR groups (46.35 ± 14.04 and 46.60 ± 12.09, respectively; p = 0.541). However, a significant difference in rSO2 levels was found between patients without return of spontaneous circulation (ROSC) and those with ROSC (40.35 ± 10.05 and 50.50 ± 13.44, respectively; p < 0.001). In predicting ROSC, rSO2 levels ≥24% provided 100% sensitivity (95% confidence interval [CI] 92-100), and rSO2 levels ≥64% provided 100% specificity (95% CI 88-100). The area under the curve for ROSC prediction using rSO2 levels during CPR was 0.74 (95% CI 0.62-0.83). CONCLUSION: A relationship between ROSC and high rSO2 levels in witnessed cardiac arrests exists. Monitoring rSO2 levels during CPR would be useful in CPR management and ROSC prediction. During CPR, MCCD or manual chest compression has no distinct effect on oxygen delivery to the brain. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT03238287.

Comparison of Endotracheal Intubation Skills With Video Laryngoscopy and Direct Laryngoscopy in Providing Airway Patency in a Moving Ambulance.

BACKGROUND: Early and successful management of the airway in the prehospital and hospital settings is critical in life-threatening situations. OBJECTIVE: We aimed to perform endotracheal intubation (ETI) by direct laryngoscopy (DL) and video laryngoscopy (VL) on airway manikins on a moving track and to compare the properties of intubation attempts. METHODS: Overall, 79 participants with no previous VL experience were given 4 h of ETI training with DL and VL using a standard airway manikin. ETI skill was tested inside a moving ambulance. The number of attempts until successful ETI, ETI attempt times, time needed to see the vocal cords, and the degree of convenience of both ETI methods were recorded. RESULTS: Overall, 22 of 79 individuals were men; mean age was 30.3 ± 4.5 years. No difference was found in the comparison of the two methods (p = 0.708). Time needed to see the vocal cords for those who were successful in their first attempt were between 1 and 8 s in both methods. In the VL method, time needed to see the vocal cords (p = 0.001) and the intubation time (p < 0.001) in the first attempt were shorter than in the DL method. The VL method was easier (p < 0.001). The success rate was 97.5% in DL and 93.7% in VL. CONCLUSIONS: The VL method is rapid and easier to see the vocal cords and perform successful ETI. Therefore, it might be preferred in out-of-hospital ETI applications.

Diagnostic Value of Hounsfield Unit and Hematocrit Levels in Cerebral Vein Thrombosis in the Emergency Department.

BACKGROUND: Unenhanced computed tomography (CT) is a frequently used imaging method in patients who are evaluated in the emergency department with suspected cerebral vein thrombosis (CVT). OBJECTIVES: The aim of this study was to investigate the usefulness of the Hounsfield unit (HU) value determined by CT and its ratio to the patient's hematocrit (Htc) value in the diagnosis of cerebral vein thrombosis. METHODS: This retrospective study evaluated 41 patients with acute cerebral venous sinus thrombosis and 41 age- and sex-matched control participants. Two experienced observers independently evaluated the CT scan and measured the attenuation of the dural sinuses. RESULTS: There was no significant difference in age, gender, hemoglobin, and Htc values between the two groups. The mean HU value was 75 ± 7 HU in the CVT group and 52 ± 6 HU in the control group (p < 0.001). The mean HU/Htc ratio was 1.9 ± 0.3 in the CVT group and 1.3 ± 0.1 in the control group (p < 0.001). The optimal threshold value for HU was determined as 66, and sensitivity at this value was 93%, and specificity was 98%. The optimal threshold value for HU/Htc was determined as 1.64, and the sensitivity at this value was 90% and the specificity was 100%. CONCLUSION: Hyperattenuation in the dural sinuses and the HU/Htc ratio in unenhanced brain CT scans have high diagnostic value in detecting CVT.

Diagnostic value of point-of-care ultrasound in deep vein thrombosis in the emergency department.

PURPOSE: Point-of-care ultrasound (POCUS) has been demonstrated as one of the primary diagnostic tools for deep vein thrombosis (DVT) screening in the emergency department, but there are quite different results in the literature regarding its diagnostic value. The aim of this study is to assess the diagnostic value of POCUS in DVT diagnosis. METHODS: Patients with a clinical suspicion of DVT who underwent POCUS and were monitored by the radiology department via ultrasonography (US) or venography for DVT were retrospectively examined. POCUS examination for DVT was performed in the femoral and popliteal regions by a two-point compression technique. The inclusion criteria were age >18 years and patients with both a POCUS report and venography or US examinations performed by the radiology department (RUS) and reported by the radiology clinic. RUS and venography were considered as the gold standards. RESULTS: The study included 266 patients. POCUS had a sensitivity of 93% (95% CI: 84-98) and specificity of 93% (95% CI: 89-96). Its positive likelihood ratio (LR+ ) was 14 (95% CI: 8-24), and its negative likelihood ratio (LR- ) was 0.08 (95% CI: 0.03-0.19). POCUS also had a positive predictive value (PPV) of 83% (95% CI: 74-89) and a negative predictive value (NPV) of 97% (95% CI: 94-99). CONCLUSIONS: Our study verifies that POCUS has high specificity and sensitivity for the examination of the popliteal and femoral veins by an emergency physician to evaluate patients with a preliminary diagnosis of DVT.

Rapid Improvement of Pulmonary Functions in Children After Transcatheter Closure of an Atrial Septal Defect.

There are very few studies in the literature on respiratory system functions and complications of children with an atrial septal defect (ASD). The aim of this study is to investigate the pulmonary functions and pulmonary complications before and after transcatheter closure in children with an ASD. In this study, pulmonary function test parameters of 30 ASD patients between 5 and 18 years of age who were eligible to be treated by transcatheter ASD closure were compared with 30 healthy children. The patients undergoing transcatheter ASD closure received pulmonary function tests (PFT) at baseline (1 day before ASD closure), and 3 months after the procedure. Forced vital capacity (FVC), forced expired volume in 1 s (FEV1), peak expiratory flow, and mean forced expiratory flow during the middle half of FVC were measured. The mean age of the 30 ASD patients was 9.59 ± 3.1 years; and 20 (66.6%) were female and 10 (33.3%) were male. The mean age of the control group was 10.15 ± 2.21 years, and 19 (63.3%) were girls and 11 (36.6%) were males. ASD patients had significantly reduced FVC (73.11 ± 24.6%; 86.05 ± 26.1; p = 0.001, respectively), and FEV1 (81.34 ± 26.2% and 99.2 ± 19.6%; p = 0.001; respectively) at baseline. But significant improvement was observed in FVC values in the 3rd-month post-closure comparison of the patient group with the control group (73.11 ± 24.6%; and 88.36 ± 14.5%; p = 0.01, respectively); FEV1 values (81.34 ± 26% and 99.54 ± 18.2%; p = 0.005, respectively) and mean forced expiratory flow between 25 and 75% of vital capacity (MEF25-75) values (94.6 ± 33.4% and 124.2 ± -24.1%; p = 0.01, respectively) were also improved. There was no statistically significant relationship between the PFT measurements at baseline and after closure of the defect and age at transcatheter closure, gender, body height, body weight, ASD diameter, Q p/Q s, right ventricle systolic pressure, or mean pulmonary artery pressure values. At the 3rd month of ASD closure, there was no significant difference in the comparison of the PFT values of the patient and control group. Disturbance in the significant flow limitation of the peripheral airway of ASD patients was observed with PFT. Better pulmonary outcomes were observed in ASD patients after transcatheter closure.

An analysis of patients that underwent computed tomography pulmonary angiography with the prediagnosis of pulmonary embolism in the emergency department.

INTRODUCTION: The purpose of this study is to analyze the frequency of other diagnoses and findings in patients that were diagnosed with or not diagnosed with PE following the CTPA in the ED and to analyze the relationship between diagnosis and D-dimer. INSTRUMENT AND METHOD: This study involves all patients that presented to the ED that underwent CTPA with the prediagnosis of PE. The items considered in this study were their reason for presenting to the ED and pretest clinical risks for PE, D-dimer, and CTPA results. FINDINGS: Of the 696 cases, the most common cause was shortness of breath (59.3%). The CTPA showed that 145 (20.83%) patients were suffering from PE. Among the remaining cases, 464 (66.66%) patients had pathological findings other than PE and 87 (12.5%) patients were reported as normal. The most common pathological results other than PE found in CTPA were atelectasis in 244 (39.9%) and ground glass in 165 (23.7%), as well as nonpulmonary results in 70 (10.05%) patients. The differences in D-dimer results of patients diagnosed with PE, patients diagnosed with another pathology, and patients with normal CTPA results were statistically significant (P < 0.001). CONCLUSION: CTPA scanning, performed on the basis of assessment scoring, helps in discovering other fatal pathologies in addition to PE.

Evaluation of the Relationship between Occupational Accidents and Obstructive Sleep Apnea Risk among Employees of a University Hospital.

Context: Occupational accidents are still one of the important causes of morbidity and mortality. Sleep apnea is a significant risk factor for occupational accidents in hospitals. Aims: To determine the frequency of occupational accidents and their relationship with the risk of obstructive sleep apnea (OSAS). Settings and Design: Cross-sectional study in a hospital setting. Methods and Material: This study was conducted on 331 hospital workers between 2019-2020. Accidents from the Social Security Institution records were used. The risk of OSAS was evaluated with Berlin Survey, daytime sleepiness with Epworth Sleepiness Scale, sleep quality with Pittsburg Sleep Quality Scale. Statistical Analysis: The Chi-square test was used for analysis; P < 0.05 was accepted as a statistical significance value. Results: Of the participants, 231 (69.8%) were female. Their ages ranged between 19 and 55; the mean age was 33.8 ± 8.0 years. The frequency of occupational accidents was 8.8%, 51.4% had a high risk of OSAS, 80.4% had high daytime sleepiness, and 53.5% had poor sleep quality. Conclusion: The study group had a high risk of sleep disorders. No relationship was found between sleep disorders and occupational accidents. More comprehensive studies are needed to clarify this relationship.

How Should We Approach Syncope in the Emergency Department? Current Perspectives.

Syncope is a clinical picture that can affect all age groups and has an important place in admissions to the emergency department. There is an important diagnostic challenge in cases where there are different clinical presentations and patients cannot express the situation clearly. Although the emergency department facilities for the diagnosis of syncope are limited, the diagnosis of many patients can be differentiated from life-threatening conditions with a detailed history and physical examination. High-risk patients should be identified and directed for definitive treatment by emergency medicine physicians. This review contains information about the management of the syncope patient in the emergency department.

Outcomes of Cardiopulmonary Resuscitation of Oncologic Patients in Emergency Department.

OBJECTIVE: To evaluate the outcomes of cardiopulmonary resuscitation (CPR) of oncological cases versus non-oncological admitted to the emergency department as out-of-hospital cardiac arrest (OHCA) or in-hospital cardiac arrest (IHCA). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Emergency Department (ED) of Eskisehir Osmangazi University Hospital, between January 2014 to January 2020. METHODOLOGY: Victims over the age of 18 years who had OHCA and IHCA were inducted. The outcomes of 109 patients with an oncological diagnosis and 109 controls without cancer underwent CPR and were compared. RESULTS: The median age of the participants was 65 (58-76) years. Patients with an oncological diagnosis were more likely to have an IHCA [OR: 2.98 (95% CI: 1.68-5.30), p <0.001]. The IHCA and OHCA rates of patients without an oncological diagnosis were similar. Solid-organ malignancies were observed in 102 patients (93.6%). The initial rhythm of 88 patients (80.7%) in the oncological arrest group was asystole versus 77 patients (70.6%) in the control group. Pulseless electrical activity was observed in 17 patients (15.6%) in the study group and in 24 patients (22.0%) in the control group. Although the non-oncological group was found to have a longer stay. No statistically significant difference was found between the study and control groups regarding duration of stay in the intensive care unit. Only one patient (2.0%) with cancer was discharged in stable state as against 10 (21.3%) of non-oncological arrests [OR: 12.97 (95% CI: 1.59-105.93), p = 0.008]. CONCLUSION: The presence of cancer is not a favourable prognostic factor for the success of CPR. KEY WORDS: Oncology, Cardiac arrest, IHCA, OHCA, Emergency department.

Vaccine-Induced Myocarditis in Two Intern Doctors in the Same Night Shift.

The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people around the globe and vaccines against the disease have started to develop. Side effects of the vaccine have been reported in the literature, including myocarditis, which has a very low incidence and with a good prognosis. This case report aims to present two medical students' vaccine-induced myocarditis cases after the first doses of BNT162b2.These patients were young males with no previous medical history and both of them had good recovery after the disease. Both of them had their vaccine very recently before the event. These cases show that myocarditis can be seen after the first dose as well.Global vaccination is the most effective prevention method against COVID-19. Considering the fact that morbidities after the disease occur more than the side effects of the vaccine, they are still the best option against the current pandemic.

A Cross-Sectional Study: Patient Privacy According to Doctors and Nurses.

Confidentiality is fundamental in building trust between patients and healthcare professionals. This research aims at presenting healthcare professionals' opinions on patient privacy, using a 5-point Likert-type scale titled "Opinion of the Healthcare Professionals on Patient Privacy," and 262 physicians' and 231 nurses' opinions were evaluated. Results showed that nurses and doctors working at emergency services got higher mean scores than those working at other units. Results revealed that doctors had the highest mean score for the item "It is important that the patient's body is not seen by other patients and professionals during the treatment," while nurses had the highest mean score for the item "I approach with due care to protect privacy in the work environment." Results of this work highlight that patient's right to privacy constitutes one of the most significant issues to be noted by healthcare professionals.

Therapeutic Dilemmas Regarding Anticoagulation, Pulmonary Embolism, and Diffuse Alveolar Hemorrhage Due to Behçet's Disease.

The use of anticoagulants is still a matter of debate in deep venous thrombosis (DVT) and other thrombotic events in Behcet's disease (BD). Anticoagulant therapy is an integral part of treatment in cases of a pulmonary embolism (PE) that develops in other disorders. The issue of how to act when a pulmonary artery thrombosis is reported in the Behçet's patient may pose a major dilemma among emergency physicians. A 61-year-old male came to our ED with a complaint of chest pain and hemoptysis. The patient had tachypnea, dyspnea, tachycardia, a decrease of breath sounds in the basal regions of both lungs, and a few crackling rales were heard in the left lung field. Chest CT angiography showed pulmonary thromboembolism in the right middle and lower lobe segment arteries with pulmonary infarction as well as ground glass densities compatible with alveolar hemorrhage. High-dose steroid and cyclophosphamide were administered immediately without anticoagulant therapy based on pulmonary vasculitis and de novo clot formation in the pulmonary circulation. Clinical improvement was observed after four days of admission. The patient remained under observation with oral prednisolone and cyclophosphamide monthly. PE is almost non-existent in patients with BD, and signs of pulmonary artery thrombosis are associated with pulmonary vasculitis. Delaying immunosuppressive therapy may result in unwanted results in these kinds of patients. This case underlines the importance of recognizing this manifestation early to prevent potentially fatal consequences.
