Furthermore, they need to be aware of the principles of ethical analysis and clinical decision-making in order to provide quality care. This study aimed to propose professional ethics codes in the emergency medicine department.</p> <p><strong>Method:</strong> This is a qualitative study, which was performed using narrative review and expert panel, and was conducted in three steps, including: literature review and preparation of the initial draft of the ethical concepts, obtaining expert opinions on this initial draft and its validation, and finalizing main ethical components in emergency medicine. In this study, we received the opinions of an expert panel including 10 medical ethicists and 12 emergency medicine specialists using a survey form.</p> <p><strong>Results:</strong> The ethical guide to emergency medicine can be formulated in 34 key ethical concepts, 6 sub-components, and 5 main components including emergency physician-patient relationship, and emergency physicians’ relationships with other professionals, students, researchers, and community.</p> <p><strong>Conclusion:</strong> Emergency care providers need to be familiar with ethical guidelines in order to improve quality of care in emergency departments. The findings of this study suggest that a guideline on patient-physician relationship as well as the emergency physicians’ ethical obligations for other professionals, students, researchers, and community should be developed in line with ethical norms.</p> 2022-01-01T00:00:00+00:00 Copyright (c) 2021 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1399 Remote Analysis and Transmission System of Electrocardiogram in Prehospital Setting; a Diagnostic Accuracy Study 2021-12-12T14:20:47+00:00 Elmira Almukhambetova murel_61@mail.ru Murat Almukhambetov murel_61@mail.ru Abdugani Musayev musaev.dr56@gmail.com Ainur Yeshmanova ayeshmanova@yandex.ru Vildan Indershiyev vildanindershiyev@gmail.com Zhadira Kalhodzhaeva zhadira_ka@mail.ru <p><strong>Introduction:</strong> One of the trends in the development of medical technologies is considered to be telemedicine. This study aimed to evaluate the accuracy of a remote electrocardiogram (ECG) analysis and transmission system in prehospital setting.</p> <p><strong>Methods:</strong> In this cross-sectional study, the data of 19,265 ECGs was gathered from emergency medical service (EMS) database of Almaty city, Kazakhstan, from 2015 to 2019. All ECGs were recorded in the prehospital setting by a paramedic, using "Poly-Spectrum" ECG recording device. Subsequently, all ECGs were sent to the cardiologist for interpretation and the findings were compared between software and cardiologist.</p> <p><strong>Results: </strong>19,265 ECGs were registered. The average time from taking ECGs to receiving an expert’s conclusion was 9.2 ± 2.5 minutes.&nbsp;The medical teams were called in 17.9% of cases after paramedic ECG recording; however, in the rest of the cases there was no need to call those teams. Using the device reduced the number of visits of specialist teams.</p> <p>The overall sensitivity, specificity, and accuracy of ECG analysis device in diagnosis of ECG abnormalities were 83.8% (95%CI: 82.6 – 84.9), 95.5% (95%CI: 95.1 – 95.8), and 93.3% (95%CI: 92.9 – 93.7), respectively.</p> <p><strong>Conclusion:</strong> The findings of this study showed the 93.3% accuracy of automatic ECG analysis device in interpretation of ECG abnormalities in prehospital setting compared with the cardiologist interpretations. Using the device causes a decrease in the number of cardiologist visits needed as well as reduction in cost and elapsed time.</p> 2022-01-01T00:00:00+00:00 Copyright (c) 2021 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1425 Nifekalant versus Amiodarone for Out-Of-Hospital Cardiac Arrest with Refractory Shockable Rhythms; a Post Hoc Analysis 2021-12-21T14:31:45+00:00 Hiraku Funakoshi hirakufunakoshi@gmail.com Shotaro Aso notelalie@gmail.com Yosuke Homma jazz.dr.homma@gmail.com Ryuta Onodera yes.onodera@gmail.com Yoshio Tahara tahara@ncvc.go.jp <p><strong>Introduction: </strong>It is still unclear that which anti-arrhythmics are adequate for treating refractory dysrhythmia. This study aimed to compare amiodarone and nifekalant in management of out-of-hospital cardiac arrest cases with refractory shockable rhythm.</p> <p><strong>Methods: </strong>This was a post hoc analysis of cases registered in a nationwide, multicentre, prospective registry that includes 288 critical care medical centres in Japan. From June 2014 to December 2017, we included all out-of-hospital cardiac arrest patients aged ≥18 years who presented with refractory arrhythmia (sustained ventricular fibrillation or ventricular tachycardia following delivery of at least two defibrillator shocks) and treated with nifekalant or amiodarone after arrival to hospital. Overlap weight was performed to address potential confounding factors.</p> <p><strong>Results: </strong>1,317 out-of-hospital cardiac arrest patients with refractory arrhythmia were enrolled and categorized into amiodarone (n = 1,275) and nifekalant (n = 42) groups. After overlap weight was performed, there were no significant intergroup differences in increased the rate of admission after return of spontaneous circulation [–5.9% (95%CI: –7.1 to 22.4); p = 0.57], 30-day favourable neurological outcome [0.1% (95%CI: –14 to 13.9); p = 0.99], and 30-day survival [–3.9% (95% CI: –19.8 to 12.0); p = 0.63].</p> <p><strong>Conclusion: </strong>This nationwide study showed that nifekalant was not associated with improved outcomes regarding admission after return of spontaneous circulation, 30-day survival, and 30-day favourable neurological outcome compared with amiodarone.</p> 2022-01-01T00:00:00+00:00 Copyright (c) 2021 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1472 Association of CT Scan Parameters with the Risk of Renal Angiomyolipoma Rupture; a Brief Report 2021-12-22T14:37:36+00:00 Razieh Heidari dr.razieh.heidari86@gmail.com Mostafa Ghadamzadeh Ghadamzadeh.m@iums.ac.ir Mansour Bahardoust mansourbahari93@gmail.com Forugh Khezrian Forugh.k67@gmail.com Afrooz Moradkhani Afroozmoradkhani@gmail.com Parmida Ghadimi parmidadm@yahoo.com Seyed Morteza Bagheri Bagheri.m@iums.ac.ir <p><strong>Introduction: </strong>Rupture of renal angiomyolipoma (AML) is an emergency and life-threatening complication. This study aimed to evaluate the association of computed tomography (CT) scan parameters with the risk of rupture in renal AMLs.</p> <p><strong>Methods: </strong>In this retrospective cross-sectional study, patients who were referred to a referral university hospital with diagnosis of AML, between 2007 and 2019, were included. Patients were divided into ruptured and non-ruptured cases based on surgery and CT scan findings and the baseline characteristics as well as CT scan parameters were compared between the two groups.</p> <p><strong>Results:</strong> 20 AML patients with the mean age of 39.6 ± 12.5 years were included (75% female). The lesion was ruptured in 8 (40%) patients. The mean size of the lesion was ‎97.0 ± 15.9 mm‎‏ in the ruptured and ‏‎72.0 ± 29.4‎‏ in the non‎-‎ruptured AML ‏‎(‎p ‎= ‎‏0.045).

This study aimed to evaluated the accuracy of serum pro-BNP and troponin I levels in PTE diagnosis.</p> <p><strong>Methods:</strong> This cross-sectional study was implemented on 267 patients with suspected PTE (sudden chest pain or sudden dyspnea) in Imam Reza Hospital in Mashhad, Iran. All patients underwent pulmonary computed tomography (CT) angiography (as the gold standard test) and their serum levels of troponin I and pro-BNP were measured. The screening performance characteristics of pro-BNP in detection of PTE cases were measured and reported using receiver operating characteristic (ROC) curve analysis.</p> <p><strong>Results:</strong> Two-hundred-sixty-seven patients with a mean age of 67.7 ±11.5 years were evaluated (60.1% male). PTE was confirmed via CT angiography in 121 patients. The area under the ROC curve of troponin I and pro-BNP in detection of PTE was 0.501 ng/mL and 0.972 pg/mL, respectively. The sensitivity and specificity of proBNP at the best cut-off point (100 pg/ml) were 85.4% and 80.2%, respectively. The sensitivity and specificity of troponin I at the best cut-off point (0.005 ng/ml) were 65.5% and 42%, respectively.</p> <p><strong>Conclusion:</strong> Due to the comparatively good sensitivity and specificity of proBNP in diagnosis of pulmonary thromboembolism, it can be employed as a diagnostic determinant in patients with suspected pulmonary thromboembolism along with other laboratory tests.</p> 2022-01-08T05:21:34+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1484 Clinical Predictors of Testicular Torsion in Patients with Acute Scrotum; a Cross-Sectional Study 2022-01-11T15:03:33+00:00 Mohammad Sazgar msazgar2000@yahoo.com Seyed Hossein Montazer hmontazer66@yahoo.com Seyed Mohammad Hosseininejad drhoseininejad@yahoo.com Fatemeh Jahanian autumnalroja@yahoo.com Behkam Rezaimehr hamedaminiahidashti@gmail.com Mohammad Behbohaninia sina.behbahani1991@yahoo.com Hamed Aminiahidashti hamedaminiahidashti@yahoo.com <p><strong>Introduction: </strong>Testicular torsion is an important and critical issue in patients with acute scrotum referring to emergency department (ED). Early detection is very important to save the testicles. This study aimed to determine the diagnostic accuracy of clinical variables in predicting the presence of testicular torsion.</p> <p><strong>Methods:</strong> This prospective cross-sectional study was done using the information of patients hospitalized from September 2015 to September 2020, with complaint of acute scrotum (ICD 10 code: N50.8), referring to ED for evaluation of the clinical predictors of testicular torsions, which were confirmed by surgery.</p> <p><strong>Results: </strong>81 patients with the mean age of 20.07 ± 9.64 (3- 45) years were studied. After surgical exploration, 70 patients (86.4%) had testicular torsion. Patients with torsion had lower age (p &lt; 0.0001), lower time from symptom to ED visit (p &lt; 0.0001), sudden onset pain (p = 0.003), left side pain (p &lt; 0.0001), and lower white blood cell (WBC) count (p = 0.001). The frequency of dysuria (p = 0.032), diarrhea/vomiting (p = 0.005), and fever (p = 0.002) was significantly lower in patients with torsion. The cremasteric reflex was absent in 57 (81.4%) cases who suffered from testicular torsion (p = 0.001). Based on the results of binary logistic regression analysis, age (B = -0.175, SE = 0.45; p &lt; 0.0001) was the sole independent predictor of testicular torsion. The highest area under the receiver operating characteristics (ROC) curve in predicting the presence of torsion belonged to lower age [91.0 (95%CI: 83.2 – 98.7)], pain in left testis [0.931 (95%CI: 0.828-0.987)], and lower WBC count [0.805 (95%CI: 0.684-0.926)], respectively.</p> <p><strong>Conclusion: </strong>It seems that clinical variables are not accurate enough to be considered as the sole predictor of testicular torsion and they should be used with caution and in combination with other available screening tools like Doppler ultrasonography in this regard.&nbsp;&nbsp;</p> 2022-01-11T08:11:11+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1507 Clinical, Laboratory and Imaging Characteristics of Hospitalized COVID-19 Patients with Neurologic Involvement; a Cross-Sectional Study 2022-01-30T15:43:15+00:00 Ali Zare Dehnavi alizared9494@gmail.com Mohammadreza Salehi mr-salehi@sina.tums.ac.ir Mehran Arab Ahmadi Mehran_arabahmadi@yahoo.com Mohammad Hossein Asgardoon Mh_asgardoon@yahoo.com Farzad Ashrafi farzad.ashrafi@gmail.com Nasrin Ahmadinejad nahmadinejad@tums.ac.ir Atefeh Behkar atefehbehkar@gmail.com Ramin Hamidi Farahani rgsramin@yahoo.com Hassan Hashemi dehghani.abs@gmail.com Abbas Tafakhori abbas.tafakhori@gmail.com Hamze Shahali hamze.shahali@ajaums.ac.ir Mohammad Rahmani mohammad.rahmanisar@gmail.com Alireza Ranjbar Naeini a.ranjbar.naeini@ajaums.ac.ir <p><strong>Introduction:</strong> Although neurologic involvement and neuroimaging abnormalities have been frequently identified in COVID-19 patients, the underlying factors remain unclear. In this study, we assessed the association of the neurological manifestations and neuroimaging features of hospitalized COVID-19 patients with their clinical, laboratory, and imaging characteristics.</p> <p><strong>Methods: </strong>This multicenter cross-sectional study was conducted between September 2020 and March 2021 at two large academic hospitals in Tehran, Iran. We used census sampling from medical records to enroll hospitalized patients with a positive COVID-19 Polymerase chain reaction (PCR) test who underwent brain imaging due to presenting any acute neurologic symptom during hospital stay.</p> <p><strong>Results: </strong>Of the 4372 hospitalized patients with COVID-19, only 211 met the inclusion criteria (35.5% with severe infection). Central nervous system and psychiatric manifestations were significantly more common in severe cases (p ≤ 0.044). Approximately, 30% had a new abnormality on their neuroimaging, with ischemic (38/63) and hemorrhagic (16/63) insults being the most common. The most frequent reasons that provoked cranial imaging were headache (27%), altered consciousness (25.6%), focal neurologic signs (19.9%), and delirium (18%). Analysis revealed a positive correlation for age, neutrophilia, lymphopenia, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) with the emergence of neuroimaging abnormalities (p ≤ 0.018). In addition, patients with new neuroimaging abnormalities had a significantly higher lung CT score than those without any pathologic findings (11.1 ± 4.8 vs. 5.9 ± 4.8, p &lt; 0.001).</p> <p><strong>Conclusion: </strong>Approximately 30% of the study population had various acute neuroimaging findings.

The main purpose of this study was to investigate the relationship between income level and hospitalization rate of COVID-19 patients‌.</p> <p><strong>Methods: </strong>A cross-sectional study was performed on 198,944 hospitalized COVID-19 patients in Tehran province between March 2020 and March 2021. Data of hospitalized COVID-19 patients was obtained from the Hospital Intelligent Management System (HIM). The income data of patients were obtained from the Iranian Database on Targeted Subsidies belonging to the Ministry of Cooperatives, Labor, and Social Welfare. Data analyses were performed using SPSS software.</p> <p><strong>Results: </strong>About 2.5% of the inpatients were from the first decile, while 20.6% were from the tenth. The share of the lower three deciles of total hospitalization was about 11%, while the share of the upper three deciles was 50%. There was a big difference between the upper- and lower-income deciles regarding death rates. In the first decile, 30% of inpatients died, while the proportion was 10% in the tenth decile.

Therefore, the present study aimed to compare the value of Glasgow coma scale (GCS) and physiologic scoring systems in predicting mortality and poor outcome of trauma patients.</p> <p><strong>Methods:</strong> This diagnostic accuracy study was conducted on multiple trauma patients admitted to the intensive care units of two hospitals in Tehran, Iran, from 21 November 2020 to 22 May 2021. The patients' demographic characteristics, length of stay in the intensive care unit (ICU), the vital signs, and the GCS on admission were recorded. Finally, the mortality, disability, and complete recovery of patients at the time of discharge were evaluated and receiver operating characteristics (ROC) curve analysis was used to compare the performance of physiologic scoring systems with GCS.</p> <p><strong>Results:</strong> 200 trauma patients with the mean age of 43.53±19.84 years were evaluated (74% male). The area under the ROC curve for New Trauma Score (NTS), Revised Trauma Score (RTS), Worthing Physiological Scoring System (WPSS), Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), Modified Early Warning Score (MEWS), National Early Warning&nbsp; Score (NEWS), Glasgow Coma Scale (GCS), Age, and Systolic Blood Pressure (GAPS) in prediction of mortality were 0.95, 0.95, 0.83, 0.89, 0.91, 0.84, 0.77, 0.98, and 0.97 respectively. The performance of GCS was statistically superior to RTS (P=0.005), WPSS (P=0.0001), RAPS (P=0.0002), REMS (P=0.002), MEWS (P&lt;0.0001), and NEWS (P&lt;0.0001). However, the performance of GCS, NTS (P=0.146), and GAPS (P=0.513) were not significantly different. Also, in prediction of poor outcomes, the AUC of GCS (0.98) was significantly higher than RTS (0.95), RAPS (0.85), REMS (0.85), MEWS (0.84), NEWS (0.77), and WPSS (0.75).</p> <p><strong>Conclusion:</strong> The GCS score seems to be a better instrument to predict mortality and poor outcome in trauma patients compared to other tools due to its high accuracy, wide application, and easy calculation.</p> 2022-04-09T13:36:24+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1567 Potential Impact of 3% Hypertonic Saline Infusion on Tramadol Poisoning-Induced Electrocardiogram Changes; a Randomized Clinical Trial 2022-04-14T12:25:56+00:00 Ali Omraninava ebrahimkarimi86@gmail.com Ahmad Mehdizade ebrahimkarimi86@gmail.com Ebrahim Karimi ebrahimkarimi86@gmail.com Amir Ghabousian ebrahimkarimi86@gmail.com <p><strong>Introduction: </strong>Tramadol is a synthetic analgesic with weak mu-opioid receptor agonist activity. Tramadol overdose is associated with adverse cardiac effects due to inhibiting cardiac Na+ and K+ channels. This study aimed to investigate the potential ameliorative role of 3% hypertonic saline on the electrocardiogram (ECG) changes in patients presenting with tramadol poisoning.</p> <p><strong>Methods: </strong>This was a single-center, controlled, randomized, single-blind clinical trial. Patients were randomized into the case (received hypertonic saline) and control (received placebo) groups. ECG was obtained twice in each group (upon arrival and following the intervention). Response to therapeutic interventions was evaluated using Wilcoxon Signed Ranks Test.</p> <p><strong>Results: </strong>A total of 76 patients were included. The mean age of patients was 24.88 ± 4.29 years, and 62 (81.6%) were male. The mean ingested dose of tramadol was 1673.68 ± 608.85 (range: 550-2750) mg. The number needed to treat and the absolute risk reduction of 3% hypertonic saline in the treatment of wide QRS were 1 (95% CI: 1.00 – 1.00) and 100%, respectively. In the treatment of long QTc, these measures were 1.9 (95%CI: 1.2 – 4.5) and 53.85% (95%CI: 22.00 – 85.69), respectively.</p> <p><strong>Conclusion: </strong>Given that hypertonic saline infusion can significantly ameliorate tramadol-mediated ECG changes, including QRS prolongation and QT lengthening, it can be regarded as a potential therapeutic strategy to prevent the development of life-threatening ventricular arrhythmias caused by tramadol toxicity.</p> 2022-04-13T00:00:00+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1510 Efficacy of Sumatriptan/Placebo versus Sumatriptan/Propofol Combination in Acute Migraine; a Randomized Clinical Trial 2022-04-14T12:25:55+00:00 Reza Farahmand Rad r-farahmandrad@kums.ac.ir Akram Zolfaghari Sadrabad a-zolfagharisa@kums.ac.ir Mohammadali Jafari malijafari@ssu.ac.ir Marzieh Ghilian marziehghilian@yahoo.com <p><strong>Introduction:</strong> Migraine headaches can cause severe pain for patients and lead them to multiple visits to the emergency department (ED). This study aimed to evaluate the efficacy of propofol + sumatriptan combination in comparison with sumatriptan alone in the management of acute migraine headaches.</p> <p><strong>Methods:</strong> This triple-blind clinical trial involved patients who referred to two emergency departments with acute migraine headaches. Patients were randomly assigned to control (sumatriptan and placebo) or intervention (propofol and sumatriptan) groups for comparison of the efficacy and side effects of treatment.</p> <p><strong>Results: </strong>In this study, 60 patients were included whose mean age was 31±8.8 years, and headaches were more common among women. After 30 and 60 minutes from the beginning of treatment, the mean pain score reduction in the intervention group was significantly greater than that in the control group (p=0.012, p=0.024). In addition, the rate of chest tightness in the control group was significantly higher than the intervention group. The&nbsp;absolute risk reduction of adverse events (Chest tightness, Bradycardia, hypotension, and etc.), in patients with acute migraine headache taking propofol and sumatriptan treatment, was 32.18% (95% CI: 8.02 – 56.35).</p> <p><strong>Conclusions:</strong> This study supports the use of propofol for treatment of acute migraine headaches and shows that combining sumatriptan with propofol is more effective in relieving migraine headaches and the associated symptoms than using sumatriptan alone.

This prospective cohort study aimed to determine factors associated with the 24-hour clinical outcome of emergency patients.</p> <p><strong>Methods:</strong> The sample included 1,630 patients, randomly selected through multi-stage stratified sampling from 13 hospitals in 13 provinces of Thailand. Data were collected during January-November 2018. Clinical outcome was determined using pre-arrest sign score. Data were analyzed via ordinal multivariate regression analysis.</p> <p><strong>Results:</strong> Factors influencing 24-hour clinical outcome of emergency patients were age (OR: 0.965; 95% CI: 0.96-0.97), having coronary vascular disease (CAD) (OR: 1.41; 95% CI: 1.05-1.88), and severity of illness based on Rapid Emergency Medical Score (REMS) (OR:1.09; 95% CI: 1.05-1.15). Self-transportation and being transported by emergency medical service ambulance with non-advanced life support (EMS-Non-ALS) did not influence clinical outcome when compared to EMS-ALS transport. Being transported from a community hospital increased pre-arrest sign score 1.78 times when compared to EMS-ALS (OR: 1.78; 95% CI: 1.17-2.72). Increased transportation distance increased the risk of poor clinical outcome (OR: 1.01; 95% CI: 1.002-1.011).

Mokdad mokdaa@uw.edu Vafa Rahimi-Movaghar v_rahimi@sina.tums.ac.ir <p><strong>Introduction</strong>: The mortality of burn injury is a serious health problem among older people. The present study aimed to determine the epidemiological characteristics of burn mortality and Years of Life Lost (YLLs) among people aged ≥ 60.</p> <p><strong>Methods</strong>: The National and Subnational Burden of Disease (NASBOD) study includes population-based cross-sectional data from the death registration system of Iran and those recorded by the cemeteries of Tehran and Esfahan were used in this study. Spatio-temporal and Gaussian process regression models were applied to estimate rates and trends of mortality and cause-specific mortality fractions. YLLs were calculated using Iranian life expectancy and the number of deaths.</p> <p><strong>Results</strong>: The mortality rate for 1990 and 2015 was 17.4 and 4.5 per 100,000, respectively. From 1990 through 2015, the annual percentage of change in burn mortality rate was -6.1% in females and -4.4% in males. During 2015, there were 326 deaths following burns in people aged 60+ with 4586 person YLLs, and in 1990 there were 523 deaths with 4862 person-YLLs. The male-female ratio for 1990 and 2015 were 0.80 and 0.88, respectively. The age-standardized mortality rate was higher than 8.5 per 100,000 in border provinces in 2015. The provinces with better socioeconomic situations, such as Tehran, had a lower mortality rate than poor provinces, such as Sistan va Baluchistan.</p> <p><strong>Conclusion</strong>: Although burn mortality in old people decreased in those 26 years, it is still high compared to high-income countries. Continued efforts to increase preventive measures and adequate access to quality care, especially in border provinces, is suggested.</p> 2022-04-27T06:17:36+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1516 Resident Productivity in the Emergency Department After Implementation of an Automated Patient Assignment System; a Brief Report 2022-04-30T12:43:09+00:00 Christian Rosenow rosenow.christian@mayo.edu Sophia Aguirre Aguirre.sophia@mayo.edu Thomas Polveroni Polveroni.thomas@mayo.edu Zachary Ginsberg Ginsberg.zachary@mayo.edu Jordan Pollock pollock.jordan@mayo.edu Stephen Traub Stephen_traub@brown.edu Douglas Rappaport Rappaport.douglas@mayo.edu <p><strong>Introduction:</strong> The clinical diversity of patients presenting to the emergency department (ED) allows emergency medicine (EM) and non-EM residents to sharpen their clinical skills. In most EDs, residents self-assign patients at their discretion. Our institution transitioned from a self-assignment-system to an automated-system, after which we sought to determine the productivity of our non-EM residents compared to the previous system.</p> <p><strong>Methods:</strong> In this retrospective cross-sectional study, resident productivity was measured as number of patient visits per hour and per 8.5-hour shift before and after the implementation of an automated patient assignment system in emergency department. The automated-system assigns one patient at the start of the shift, another 30 minutes later, and one patient every hour thereafter, throughout the shift.</p> <p><strong>Results:</strong> 28 residents performed 406 total shifts prior to implementation and 14 residents performed 252 total shifts post-implementation. The average number of patient visits per hour significantly increased from 0.52 ± 0.18 (95% CI 0.45-0.59, IQR 0.43-0.60) to 0.82 ± 0.11 (95% CI 0.75-0.88, IQR 0.74-0.89) after implementation of our assignment system (p&lt;0.00001; figure 1). Additionally, the average number of patient visits per 8.5-hour shift significantly increased from 4.46 ± 1.53 (CI 3.86-5.05, IQR 3.66-5.08) to 6.52 ± 0.86 (CI 6.02-7.02, IQR 5.90-7.09) after the implementation of our system (p&lt;0.00001; figure 1).</p> <p><strong>Conclusion: </strong>These findings warrant further evaluation of the impact of patient assignment systems on trainee education.</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1554 Demographic and Clinical Characteristics of 907 Cases with Naltrexone Intoxication; a 14-Year Cross-Sectional Study 2022-05-01T12:44:10+00:00 Mitra Rahimi mrahimi744@gmail.com Alireza Kargar alireza.kargar@yahoo.com Delara Hazegh Fetratjoo delara.hazegh@gmail.com Sayed Masoud Hosseini hoseinim902@gmail.com Arezou Mahdavinejad arezouma@yahoo.com Shahin Shadnia shahin1380@gmail.com <p><strong>Introduction:</strong> Opioids have been the leading cause of death from poisoning in Iran for several years. This study aimed to evaluate the clinical and para-clinical presentations of naltrexone intoxication, its toxic dose, and its epidemiological properties.</p> <p><strong>Methods</strong><strong>:</strong> This retrospective cross-sectional study was conducted on medical records of patients presenting to Toxicology Department of Loghman Hakim Hospital, Tehran, Iran, following naltrexone intoxication, from 2002 to 2016. Patients’ demographic and laboratory data, clinical signs, supposed ingested dose, and intent of naltrexone consumption were collected, analyzed, and then interpreted.</p> <p><strong>Results:</strong> 907 patients with the mean age of 36.6 ±11.7 years were evaluated (94.3% male).&nbsp; The mean amount of naltrexone consumed by the intoxicated patients reported in the medical records was 105.8 ± 267.8 mg. One hundred thirty patients (14.3%) used naltrexone to treat substance use disorder. Two hundred eighty-seven poisoned patients (31.6%) were current opium users who intentionally or unintentionally used naltrexone concomitantly. The most common symptoms observed in these patients were agitation (41.8%), vomiting (16.4%), and nausea (14.8%). Among patients with naltrexone poisoning, 25 patients were intubated (2.8%), and three passed away. Aspartate aminotransferase (AST) levels were significantly higher in patients intoxicated with naltrexone who needed intubation (p = 0.02).</p> <p><strong>Conclusion</strong>: The probability of intubation of cases with naltrexone intoxication was associated with AST elevation. It seems that, the number of intensive care unit (ICU) admissions and mortality rates are not high among these patients.</p> 2022-05-01T06:09:46+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1571 The Challenges of Emergency Medical Services Response to Arasbaran Twin Earthquakes; a Content Analysis 2022-05-02T12:44:32+00:00 Mahboub Pouraghaei pouraghaeim@yahoo.com Javad Babaie javad1403@yahoo.com Laleh Rad Saeed RADLALEH18@gmail.com <p><strong>Introduction:</strong> One of the most important concerns in responding to disasters is providing Basic Life Support (BLS) services.

Data were collected through Focused Group Discussions (FGD) and semi-structured in-depth interviews with purposively-selected EMS paramedics and officials in East Azerbaijan Province, Iran. To form the main categories, the interviews were encoded in three stages and the similar codes were placed under the same subcategories and merged.</p> <p><strong>Results:</strong> A total of 26 EMS paramedics participated in the study. The codes extracted from the interviews, after three stages of reduction, were placed in the top ten categories, including the lack of preparedness and coordination, dead bodies' management challenges, responders’ psychosocial support, deficiencies in supplies and ambulances, difficulty of access to rural areas, volunteer management, non-documentation of the experiences, communication challenges, recalling, and deploying of EMS responders.&nbsp;</p> <p><strong>Conclusion:</strong> Timely response of the EMS and paramedics’ sense of responsibility for providing services were positive and successful points about the emergency response operations.

This study aimed to compare the accuracy of Quick Sequential Organ Failure Assessment (qSOFA), Confusion, Urea, Respiratory Rate, Blood Pressure and Age Above or Below 65 Years (CURB-65), and Systemic Inflammatory Response Syndrome (SIRS) scores in predicting the in-hospital mortality of COVID-19 patients.</p> <p><strong>Methods: </strong>This prognostic accuracy study was performed on 225 ICU-admitted patients with a definitive diagnosis of COVID-19 from July to December 2021 in Tehran, Iran. The patients' clinical characteristics were evaluated at the time of ICU admission, and they were followed up until discharge from ICU. The screening performance characteristics of CURB-65, qSOFA, and SIRS in predicting their mortality was compared.</p> <p><strong>Results:</strong> 225 patients with the mean age of 63.27±14.89 years were studied (56.89% male). The in-hospital mortality rate of this series of patients was 39.10%. The area under the curve (AUC) of SIRS, CURB-65, and qSOFA were 0.62 (95% CI: 0.55 - 0.69), 0.66 (95% CI: 0.59 - 0.73), and 0.61(95% CI: 0.54 - 0.67), respectively (p = 0.508). In cut-off ≥1, the estimated sensitivity values of SIRS, CURB-65, and qSOFA were 85.23%, 96.59%, and 78.41%, respectively.

This study aimed to evaluate the impact of this pandemic on presentation to emergency department (ED) with urologic complaint.</p> <p><strong>Method: </strong>This cross-sectional study was conducted at a tertiary urology referral center in Tehran, Iran. The data of all ED admissions were collected and the frequency of admissions with urologic complain and their outcomes were compared between two 90-day periods (before and during COVID-19 era).</p> <p><strong>Results: </strong>480 ED admissions were studied. The number of patients visiting the ED with urologic complaint during COVID-19 era was significantly lower than the same period in the pre-COVID-19 period (125 vs. 355 admissions; p = 0.01). The mean hospitalization days for patients in the pre-COVID-19 period were significantly higher (5.6 ± 4.4 vs. 3.2 ± 4.2 days; p &lt;0.001). The most common patient complaints before and during COVID-19 period were flank pain (32.7%) and gross hematuria (32.8%), respectively. The number of patients discharged against medical advice in the COVID-19 period was significantly higher than before (22 (17.6%) vs. 10(2.8%); p &lt; 0.001).

However, improper use will be just as dangerous. The present study aimed to investigate the level of nurses’ knowledge on properly using oxygen.</p> <p><strong>Method: </strong>This was a cross-sectional study with a minimum sample size of 72 nurses who were randomly selected from various wards of Masih Daneshvari Hospital, Tehran, Iran. To determine the level of knowledge about oxygen therapy, a questionnaire was used to collect data. This questionnaire consists of seven items, each of which is designed to determine the level of the individual’s knowledge about the various details of oxygen therapy.</p> <p><strong>Results:</strong> Seventy-eight nurses with the mean age of 35.80±7.42 years participated in the study (87% female). The mean knowledge score of nurses regarding oxygen therapy was 8.89 ± 2.79 out of 16 points. 84.6% of the nurses were able to differentiate various types of oxygen masks. Accordingly, 94.9% of nurses had good knowledge on oxygen humidification. Also, 50% of the nurses had sufficient knowledge about the amount of oxygen flow produced by different masks. 10.3% of the nurses could choose the most appropriate mask for different clinical conditions. 6.4% of the nurses had knowledge of working with flowmeters, and 15.4% of the nurses had sufficient information about the maximum level of oxygen required for the patient. 17.9% of the nurses were familiar with measuring the appropriate amount of oxygen for patients.

However, a statistically significant relationship was reported between nurses' related work experience and their knowledge of the proper use of oxygen (p = 0.03).</p> <p><strong>Conclusion:</strong> In general, the nurses’ knowledge at Masih Daneshvari Hospital on how to properly use oxygen is at a moderate level. Nurses' knowledge in some areas, such as working with the flowmeter, choosing the suitable mask for specific clinical conditions, and the maximum oxygen required for patients, is meager and requires training intervention.</p> 2022-05-18T08:40:24+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1421 Incidence of Pediatric Perforated Appendicitis during the COVID-19 Pandemic; a Systematic Review and Meta-Analysis 2021-11-27T13:58:02+00:00 Gholamreza Motazedian gmotazedian@gmail.com Poorya Aryanpoor Aryanpoorp@jums.ac.ir Ehsan Rahmanian ehsanrahmanian90@yahoo.com Samaneh Abiri samaneh.abiri@gmail.com Navid Kalani navidkalani@ymail.com Naser Hatami naserohatami@gmail.com Farhad Bagherian dr_f_bagherian@yahoo.com Mohammad Etezadpour EtezadpourM@mums.ac.ir Roohie Farzaneh Farzanehrh@mums.ac.ir Fatemeh Maleki maleki.f@bums.ac.ir Mahdi Foroughian foroughianmh@mums.ac.ir Mojtaba Ghaedi ghamojtaba247@gmail.com <p><strong>Introduction</strong>: COVID-19 has affected the pattern of referral to medical centers and quarantine against COVID-19 might delay referral and management of surgical emergencies. This study aimed to compare the pooled event rate of pediatric perforated appendicitis before and during the COVID-19 pandemic.</p> <p><strong>Methods</strong>: This was a systematic review and meta-analysis study based on the PRISMA guidelines.&nbsp; Scopus, Web of Sciences, and PubMed databases were searched for studies reporting the rate of perforated appendicitis based on the post-appendectomy observations or imaging methods. The Egger bias test and funnel plot were used to detect and depict publication bias.

However, the possible benefits of earlier decompression are unclear. Thus, the present meta-analysis aims to investigate the existing evidence regarding the efficacy of ultra-early decompression surgery (within 12 hours after SCI) in improving patients’ neurological status.</p> <p><strong>Methods: </strong>A search was performed in Medline, Embase, Scopus and Web of Science electronic databases, until the end of August 2021. Cohort studies and clinical trials were included in the present study. Exclusion criteria were absence of an early or late surgery group, failure to report neurological status based on the American spinal injury association impairment scale (AIS) grade, failure to perform the surgery within the first 12 hours after SCI, and duplicate reports and review articles. Two independent reviewers performed data collection, and risk of bias and certainty of evidence assessments. The outcome was reported as odds ratio (OR) and 95% confidence interval (CI).</p> <p><strong>Results: </strong>Data from 16 articles, which studied 868 patients, were included. Compared to early or late decompression surgery, ultra-early decompression surgery significantly improves patients’ neurological status (OR = 2.25; 95% CI: 1.41 to 3.58). However, ultra-early surgery in thoracolumbar injuries is not significantly more effective than early to late surgery. Moreover, ultra-early surgery in patients with a baseline AIS A increases the chance of neurologic resolvent up to 3.86 folds (OR=3.86; 95% CI: 1.50 to 9.91). Contrastingly, ultra-early surgery does not result in significant improvement compared to early to late surgery in patients with AIS B (OR = 1.32; 95% CI: 0.51 to 3.45), AIS C (OR = 1.83; 95% CI: 0.72 to 4.64), and AIS D (OR = 0.99; 95% CI: 0.31 to 3.17).</p> <p><strong>Conclusion: </strong>Current guidelines emphasize that spinal decompression should be performed within 24 hours after SCI, regardless of injury severity and location. However, results of the present study demonstrated that certain considerations may be taken into account when performing decompression surgery: 1) in patients with AIS A injury, decompression surgery should be performed as soon as possible, since its efficacy in neurological improvement is 3.86 folds higher in the first 12 hours after injury. 2) ultra-early decompression surgery in patients with cervical injury is more effective than in patients with thoracic or lumbar injuries. 3) postponing decompression surgery to 24 hours in SCI patients with AIS B to D does not significantly affect the neurological outcome.</p> 2022-01-31T05:14:46+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1526 Accuracy of Triage Systems in Disasters and Mass Casualty Incidents; a Systematic Review 2022-04-30T12:43:09+00:00 Jafar Bazyar bazyar.jafar@gmail.com Mehrdad Farrokhi mfarokhikhb@yahoo.com Amir Salari salaramir@gmail.com Hamid Safarpour h.safarpour@sbmu.ac.ir Hamid Reza Khankeh ha.khankeh@uswr.ac.ir <p><strong>Introduction</strong>: To prioritize patients to provide them with proper services and also manage the scarce resources in emergencies, the use of triage systems seems to be essential. The aim of this study was to evaluate the accuracy of the existing triage systems in disasters and mass casualty incidents.</p> <p><strong>Methods</strong>: The present study is a systematic review of the accuracy of all triage systems worldwide. The results of this study were based on the articles published in English language journals. In this research, all papers published from the beginning of 2000 to the end of 2021 were sought through different databases. Finally, a total of 13 articles was ultimately selected from 89 articles.</p> <p><strong>Results</strong>: 13 studies on the accuracy of triage systems were reviewed. The START, mSTART, SALT, Smart, Care Flight, ASAV, MPTT, Sieve and ESI triage systems, had an accuracy, sensitivity, and specificity of less than 90%. Only the Smart triage system had an overall accuracy of more than 90%.</p> <p><strong>Conclusion</strong>: According to the findings of the current systematic review, the performance of the existing triage systems in terms of accuracy of prioritizing the injured people and other performance indexes is not desirable. Therefore, to improve the performance and increase the precision of triage systems, the world nations are recommended to change or revise the indexes used in triage models and also identify other influential factors affecting the accuracy of triage systems.</p> 2022-04-30T06:10:57+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1573 Orthopedic Trauma During Pregnancy; a Narrative Review 2022-05-18T09:29:23+00:00 Meisam Jafari Kafiabadi dr.jafari8567@yahoo.com Amir Sabaghzadeh dramirsabbaghzadeh@gmail.com Seyyed Saeed Khabiri saeed.khabiri@gmail.com Mehrdad Sadighi mehrdad_1330@yahoo.com Amir Mehrvar drmehrvar@sbmu.ac.ir Farsad Biglari biglari.farsad@gmail.com Adel Ebrahimpour adel.ebrahimpour@yahoo.com <p><strong>Introduction:</strong> Blunt traumas, like road accidents and falls, are common causes of injuries to pregnant women, and the major risk factors are young age and low socioeconomic level. Due to physiological and anatomical changes specific to pregnancy, such as changes in blood pressure and hemoglobin drop, trauma management involves certain complexities. Physical trauma is estimated to cause at least 1 complication in every 12 pregnancies. This study aims to evaluate orthopedic trauma during pregnancy and appreciate the different approaches to circumvent the resultant challenges.</p> <p><strong>Methods: </strong>&nbsp;We reviewed 55 articles, published on orthopedic trauma during pregnancy between 2011 and 2021. The articles were identified by searching PubMed, google-scholar, Scopus, and Science-Direct. We utilized the search terms: fall in pregnancy, traumas in pregnancy, motor vehicle accident/crash in pregnancy, blunt trauma in pregnancy, pregnant trauma patient, penetrating injury during pregnancy, assault, interpersonal violence in pregnancy, and mortality and pregnancy.</p> <p><strong>Results: </strong>According to available reports, after stabilizing the pregnant patient, diagnostic procedures, including radiography, and even gadolinium-based techniques when needed, can be performed to examine extensive trauma. In contrast to elective orthopedic surgery, emergency orthopedic surgeries, including reduction of open fractures, should be performed promptly.</p> <p><strong>Conclusion:</strong> Based on our investigation, pregnant women with orthopedic injuries that are severe, or even seemingly less severe, experience significantly increased adverse pregnancy outcomes, which include preterm birth, placental abruption, poor infant condition at birth, infant death, and even maternal death.</p> 2022-05-18T00:00:00+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1430 Removal of Coin Cell Lithium Battery Lodged in the Pediatric Pharyngoesophageal Junction by Rigid Esophagoscopy; a Case Report 2021-12-12T14:20:47+00:00 Hisataka Ominato h-ominato@asahikawa-med.ac.jp Takumi Kumai t-kumai@asahikawa-med.ac.jp Yasuaki Harabuchi hyasu@asahikawa-med.ac.jp <p>A coin cell lithium battery is a common foreign body that can become lodged in the pediatric pharyngoesophageal junction. Because the voltage of such batteries is relatively high, their rapid removal is necessary to avoid mucosal necrosis. Despite being the initial choice for removal, flexible endoscopy cannot remove such foreign bodies from the esophagus. Various removal methods, including rigid esophagoscopy, should be considered for removing lithium coin cell batteries. The transcervical approach is feasible for removing esophageal foreign bodies, but it carries the risk of complications such as esophageal stenosis. Here we report a case of lithium coin battery ingestion that was successfully removed using a rigid esophagoscope. A 2-year-old girl was referred to a local doctor with cough and general fatigue. Chest X-ray and flexible endoscopy revealed a coin cell lithium battery stuck in the pharyngoesophageal junction, but it could not be removed. The foreign body was removed using Nishihata forceps through a rigid esophagoscope under general anesthesia.</p> 2022-01-01T00:00:00+00:00 Copyright (c) 2021 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1449 A 25-Year-Old Chronic Ketamine User with Urinary Symptoms; a Case Report 2022-02-01T10:38:51+00:00 Chin-Chu Wu M002001@ms.skh.org.tw Aming Chor-Ming Lin amingphd@yahoo.com.tw <p>Ketamine is mainly used for short-acting general anesthesia, chronic pain, sedation, depression, and bipolar disorder.

Closed reduction is not feasible due to entrapped volar plate and/or coexisting fractures. Various approaches and techniques have been proposed for treatment of complex MCP dislocation; however, controversies exist over which one is superior. This study describes a right-handed 14-year-old boy who fell on the outstretched hand and sustained a dorsal dislocation of the left index MCP joint. The dislocation was complicated by an epiphyseal metacarpal head fracture with dorsal-ulnar displacement of the osteochondral fragment. The patient underwent open reduction through the dorsal approach, and the metacarpal head was fixed via the two-screw technique. The patient resumed left-hand function after six weeks. At the two-year follow-up, the range of motion and grip strength were normal, the patient was pain-free, and no sign of growth disturbance or joint stiffness was detected. Dorsal surgical approach with screw fixation is a feasible technique for the treatment of complex MCP dislocation, especially when it is complicated by a large epiphyseal head fracture.</p> 2022-02-09T16:38:20+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1498 Inferior Hip Dislocation in a 60-Year-Old Man; a Case Report 2022-02-27T11:25:29+00:00 Ali Yeganeh Yeganeh.a@iums.ac.ir Nader Tavakoli tavakoli.n@iums.ac.ir Mohammad Soleimani soleimani1995m@gmail.com Seyed Nima Taheri nimat92@yahoo.com Sahand Cheraghiloohesara Sahand.cheraghi@gmail.com <p>Inferior hip dislocation or luxatio erecta femoris is among the rarest hip dislocations, which has been described in limited studies. The patients usually present with their hip in flexion, abduction, and external rotation. Hip dislocation is an orthopedic emergency, and a reduction needs to be performed promptly to avoid devastating complications such as avascular necrosis. Here, we present a rare case of inferior hip dislocation in a 60-year-old man following a car-motorcycle collision. The patient presented to the emergency department with left hip flexion, abduction, external rotation, and inability to move his leg due to pain. Closed reduction under procedural sedation was attempted in the emergency department once, which was unsuccessful. The patient was then taken to the operating room for another attempt of closed reduction under general anesthesia. The patient was discharged after two days with pin traction and double crutches. After two weeks, the pin was removed, and full weight-bearing was permitted. After 12 weeks, the patient had mild pain with unusual activity and slight limping; however, imaging revealed no signs of any complications.</p> 2022-02-27T00:00:00+00:00 Copyright (c) 2022 Archives of Academic Emergency Medicine https://journals.sbmu.ac.ir/aaem/index.php/AAEM/article/view/1535 Right Upper Quadrant Pain Following Endoscopic Retrograde Cholangiopancreatography; a Case Report 2022-03-16T11:48:32+00:00 Lan Thi Nguyen dr.nguyenlanvd@gmail.com Dang Hai Do dangsp94@gmail.com An Duc Thai thaiducan.hmu@gmail.com Hoa Thi Nguyen hoacoi2510@gmail.com <p>Endoscopic retrograde cholangiopancreatography (ERCP) is a standard for diagnosing and treating hepato-pancreatico-biliary (HPB) diseases in clinical settings. ERCP-related complications are relatively common, ranging from 4 to 30%. The most common one is acute pancreatitis. ERCP-related necrotizing pancreatitis accounts for 7.7% of ERCP-related pancreatitis cases.
