Exploring the effective elements on the personal and professional development among health-care providers: A qualitative study.

BACKGROUND: A new domain of "personal and professional development" was introduced as a core competency of health-care providers. This study aimed to explore the experiences of learners and faculty members about what competencies or skills were essential for the professional development and success of health-care providers. MATERIALS AND METHODS: This is a qualitative study using an inductive content analysis approach in 2019-2020. In the present study, 58 academic faculty members participated by purposeful sampling including ten associate professors (17.24%) and 24 assistance professors (41.37%), in addition to 23-year medical residents (20.65%) and 4th-year nursing students (20.65%). Individual and group interviews were conducted. Data were analyzed by the inductive content analysis approach introduced by Graneheim and Lundman. RESULTS: The qualitative data were classified in 953 open codes and eight categories, which were further divided into four main categories: "socio-emotional skills," "life-long learning skills," "coping skills," and "well-being strategies." CONCLUSIONS: The present results showed socioemotional and coping skills affect interpersonal and professional interactions that contributed to their improved health-care providers' capabilities. Participants also considered lifelong learning as influential in developing professional capabilities and keeping their knowledge and skills up-to-date for accountability to duties. Moreover, using well-being strategies protects the mental and physical health of health-care providers. These skills are synergistic, and their combination can have a significant role in improving the personal and professional capabilities.

Exploring the challenges of professional identity formation in clinical education environment: A qualitative study.

INTRODUCTION: This study aimed to explore the challenges of professional identity formation at clinical education environments from the faculty members' viewpoints. METHODS: This is a qualitative study. The population consisted of clinical faculty members of Tehran University of Medical Sciences. In this study, 39 faculty members participated in an in-depth semi-structured interview. To analyze the data, conventional content analysis approach was used. Open coding was extracted from the participants' statements that represented their experiences. Then, based on their similarities, the codes were classified. Subcategories were emerged and after arranging, they were classified into categories based on their relationships. RESULTS: Instability of professional commitment, patient-centeredness as the missing loop care and treatment, and inappropriate conductive context were explored as the challenges of professional identity in clinical educational environment. CONCLUSION: According to the results of the study, the formation of professional identity among the providers is not an easy task because many factors affect the formation of professional identity. Therefore, a comprehensive shift towards forming the professional identity at individual and organizational level should be planned.

Point-of-care ultrasound modalities in terms of diagnosing acute decompensated heart failure in emergency department; a diagnostic accuracy study.

This study aimed to compare the diagnostic accuracy of heart, lung and inferior vena cava (IVC) ultrasonography modalities, alone and combined, for possible added accuracy in diagnosing acute decompensated heart failure (ADHF), in a group of patients with the final diagnosis of ADHF based on plasma level of B-type natriuretic peptide (BNP) as the standard. The present study is a diagnostic accuracy study, which was carried out in the emergency department of Imam Khomeini hospital, affiliated to Tehran University of Medical Sciences, in 2014-2015. All patients over 18 years old, who were referred to emergency department with complaint of acute dyspnea were regarded as eligible and no exclusion criteria were considered. All ultrasounds were performed by a trained emergency medicine resident and then saved and classified for each patient, separately, and reviewed by the attending emergency medicine physician. In this study, patients with BNP levels higher than 500 pg/ml were considered positive for dyspnea caused by heart failure. A total of 120 patients with an average age of 60.83 ± 16.528 years were studied, 64 (53%) of which were male. In total, 47.5% of patients had a BNP level over 500 pg/ml. Among patients with positive ultrasound, 94.7% were true positive and among those with a negative ultrasound, 61.4% were true negative. Based on the findings, B-line ≥ 10 has the highest specificity and left ventricular ejection fraction (LVEF) < 45% has the highest sensitivity. The combination of LVEF and IVC collapsibility index (IVC-CI), LVEF and BLC, IVC-CI and BLC, and IVC-CI and BBPC had a higher specificity rate and combination of LVEF and BBPC and BLC and BBPC had the highest sensitivity. Sensitivity, specificity, positive predictive value and negative predictive value of all three ultrasounds combined were 31.6%, 98.4%, 94.7% and 61.4%, respectively. In this study, the diagnostic accuracy of double and triple ultrasonography of heart, lung and IVC in the diagnosis of ADHF was very high, among which triple ultrasonography was more preferable.

Comparison of exogenous melatonin versus placebo on sleep efficiency in emergency medicine residents working night shifts: A randomized trial.

BACKGROUND: Sleep deprivation resulting from night shifts, is a major cause of burnout among physicians. Exogenous melatonin may improve sleep quality in night-shift workers. The study aims to compare the effectiveness of melatonin versus placebo on sleep efficiency in emergency medicine (EM) residents. METHODS: A randomized, double-blind, replicated crossover trial was performed on EM residents. This study consisted of 4 phases within a month with intervention periods of 2 nights and washouts of 6 days. In our study, EM residents had nine-hour shifts on 6 consecutive days, 2 mornings, 2 evenings and 2 nights and then 2 days off. At the end of shifts' cycle, 24 EM residents were given 3 mg melatonin or placebo (12 in each arm of the study) for 2 consecutive nights after the second night shift with crossover to the other arm after a six-day off drug. This crossover intervention was repeated for two more another time. Finally, we created 48 cases and comparisons in each arm. Different items related to sleep quality were assessed and compared both within the same group and between the two groups. RESULTS: In the melatonin group, daytime sleepiness (calculated by Karolinska Sleep Scale) had a significant reduction after taking the second dose of drug (P=0.003) but the same result was not observed when comparing the 2 groups. Mood status (calculated by Profile of Mood States) showed no remarkable difference between the 2 groups. CONCLUSION: Melatonin might have a limited benefit on sleep quality in EM residents working night shifts.

Pain management of acute limb trauma patients with intravenous lidocaine in emergency department.

INTRODUCTION: This study was designed to assess the possible superiority of intravenous lidocaine to morphine for pain management. METHODS: This was a randomized double blind controlled superiority trial, carried on in the emergency department (ED). Traumatic patients older than 18-year-old with the complaint of acute pain greater than 4 on a numeric rating scale (NRS) from 0 to 10 on their extremities were eligible. One group received IV lidocaine (1.5 mg/kg), and the other received IV morphine (0.1mg/kg). Pain scores and adverse effects were assessed at 15, 30, 45 and 60 minutes and patients' satisfaction was evaluated two hours later. A minimum pain score reduction of 1.3 from baseline was considered clinically significant. RESULTS: Fifty patients with the mean age of 31.28±8.7 were enrolled (78% male). The demographic characteristics and pain scores of the two groups was similar. The on-arrival mean pain scores in two groups were, lidocaine: 7.9±1.4 and morphine: 8.0±1.4 (p=0.57) and after 1 hour were, lidocaine: 2.28±1.2 and morphine: 3.2±1.7. Although the pain score decreased significantly in both group (p=0.027), there were not any clinically and statistically significant difference between the two groups (p=0.77). Patients' satisfaction with pain management in both groups were almost similar (p=0.49). CONCLUSION: The reduction in pain score using IV lidocaine is not superior to IV morphine in adult ED patients with traumatic limb pain.

Pain Management Using Acupuncture Method in Migraine Headache Patients; A Single Blinded Randomized Clinical Trial.

BACKGROUND: There were numerous studies using acupuncture for pain relief and in most, the effect of this technique on preventing migraine attacks has been investigated. In those several studies that surveyed the effect of acupuncture on treatment of migraine headaches, the conclusion was not completely persuaded and they suggested further researches on this topic. OBJECTIVES: The purpose of this study is to examine the effect of acupuncture on controlling acute migraine attacks. METHODS: This study was a single blinded randomized clinical trial that was conducted on patients with a diagnosis of acute migraine attacks. At the time of reference, the patient's pain intensity was measured and recorded in a written checklist. Acupuncture was done in the intervention group with thin metallic needles, which enter certain points in the ear's skin; including shen men, autonomic, thalamus, frontal, and temple. In the placebo group, similar needles were used, however, they were inserted into unusual points. Thereafter, in 30 minutes, one, two, and four hours after the treatment, the pain intensity was also asked and compared with the reference time's score. RESULTS: A total of 60 patients with the mean age of 31.4 ± 7.6 years were enrolled and 83.3% of them were women. There was no significant difference between two groups in terms of the baseline characteristics of participants including age, sex and pain duration before admission (P > 0.05). According to the results, there was a significant difference between the two groups on the checkpoints of 15, 30, 45, and 60 minutes after acupuncture (P < 0.05); however, the pain scores were not statistically different between the two groups on two, three, and four hours after intervention (P > 0.05). CONCLUSIONS: Based on the findings of our study, although the pain score was lower in the intervention group than the control group during first hour after the acupuncture, there was no significant change in pain score thereafter. Comparison of the two groups showed no differences between acupuncture and placebo acupuncture on decreasing the mean pain score.

Abdominal and pelvic CT scan interpretation of emergency medicine physicians compared with radiologists' report and its impact on patients' outcome.

PURPOSE: In this study, the impact of contrast-enhanced abdominopelvic CT scan interpretations by emergency medicine team on patients' morbidity and mortality was evaluated and their interpretations were compared to radiologists' reports. METHODS: During a 3-month period, all patients who had undergone a contrast-enhanced abdominopelvic CT scan at the emergency department enrolled in this study. All CT scans were interpreted blindly by the emergency medicine (ED) attending physicians and the patients were treated accordingly. Radiologists reported all the CT scans within 12 h. Radiologists' reports were put into the agreement or disagreement group retrospectively. A panel of experts further evaluated the disagreement groups' medical charts and placed them in clinically significant or insignificant group based on the follow-up for 28 days. RESULTS: In this study, 170 CT scans were interpreted. The agreement rate was 68.2%. In the clinically significant disagreement group, eight patients did not receive the required treatment and three patients were over treated. Although the overall mortality rate was 5, none could have been prevented by a prompt radiologist's report. The disagreement group had longer hospital stay (p = 0.006) and transfer to other wards (p = 0.035). The inter-rater reliability between emergency medicine attending physicians and attending radiologists was substantial (kappa = 0.77) and statistically significant (p < 0.0001). CONCLUSION: Our findings support the cautious use of ED physicians' CT scan interpretations for patients' management. Ideally, the ED physicians should utilize a real-time radiologist interpretation in critical patients. This collaboration will result in better patient management.

Vapocoolant Spray Effectiveness on Arterial Puncture Pain: A Randomized Controlled Clinical Trial.

Arterial blood gas (ABG) sampling is a painful procedure with no perfect technique for quelling the discomfort. An ideal local anesthesia should be rapid, easy to learn, inexpensive, and noninvasive. This study was aimed to compare pain levels from ABG sampling performed with vapocoolant spray in comparison to placebo. We hypothesized that pretreatment with the vapocoolant would reduce the pain of arterial puncture by at least 1 point on a 10 point verbal numeric scale. We have evaluated the effectiveness of a vapocoolant spray in achieving satisfactory pain control in patients undergoing ABG sampling in this randomized placebo controlled trial. Eighty patients were randomized to 2 groups: group A, who received vapocoolant spray, and group B, who received water spray as placebo (Control group). Puncture and spray application pain was assessed with numerical rating scale (0, the absence of pain; 10, greatest imaginable pain) and number of attempts was recorded. The pain score during ABG sampling was not lower in group A compared with group B significantly (4.78±1.761 vs. 4.90±1.837; P:0.945). This study showed that while the spray exerts more application pain, the number of attempts required for ABG sampling was not significantly lower in group A compared with group B (1.38±0.54 vs. 1.53±0.68; P=0.372). Vapocoolant spray was not effective in ABG pain reduction, had milder application pain compared to placebo (P<0.05), but did not reduce sampling attempts. At present, this spray cannot be recommended for arterial puncture anesthesia, and further study on different timing is necessary.

Preferred view and transducer in lumbar ultrasound in overweight and obese patients.

BACKGROUND: Ultrasound can be used to facilitate lumbar puncture, especially in obese patients. METHODS: In this study, midline and paramedian approaches with curved and linear transducers were compared in patients with Body Mass Index (BMI) above 25 kg/m2 for the identification of spinal landmarks. In each view, six major landmarks, including spinous process, ligamentum flavum, laminae, epidural space, subarachnoid space and posterior longitudinal ligament, were detected by emergency medicine residents and were then reviewed by radiologists. RESULTS: Sixty patients with a mean BMI of 29.18 enrolled in the study. This study showed that a curved transducer detected major landmarks more accurately compared to a linear transducer. There was also a poor kappa correlation between these transducers in the midline and paramedian approaches. CONCLUSION: This study showed that ultrasound can detect lumbar landmarks in overweight and obese patients, with the paramedian approach and a curved transducer being superior to the midline approach and a linear transducer in detecting these landmarks.

Artificial Intelligence-Based Triage for Patients with Acute Abdominal Pain in Emergency Department; a Diagnostic Accuracy Study.

INTRODUCTION: Artificial intelligence (AI) is the development of computer systems which are capable of doing human intelligence tasks such as decision making and problem solving. AI-based tools have been used for predicting various factors in medicine including risk stratification, diagnosis and choice of treatment. AI can also be of considerable help in emergency departments, especially patients' triage. OBJECTIVE: This study was undertaken to evaluate the application of AI in patients presenting with acute abdominal pain to estimate emergency severity index version 4 (ESI-4) score without the estimate of the required resources. METHODS: A mixed-model approach was used for predicting the ESI-4 score. Seventy percent of the patient cases were used for training the models and the remaining 30% for testing the accuracy of the models. During the training phase, patients were randomly selected and were given to systems for analysis. The output, which was the level of triage, was compared with the gold standard (emergency medicine physician). During the test phase of the study, another group of randomly selected patients were evaluated by the systems and the results were then compared with the gold standard. RESULTS: Totally, 215 patients who were triaged by the emergency medicine specialist were enrolled in the study. Triage Levels 1 and 5 were omitted due to low number of cases. In triage Level 2, all systems showed fair level of prediction with Neural Network being the highest. In Level 3, all systems again showed fair level of prediction. However, in triage Level 4, decision tree was the only system with fair prediction. CONCLUSION: The application of AI in triage of patients with acute abdominal pain resulted in a model with acceptable level of accuracy. The model works with optimized number of input variables for quick assessment.

Distance Learning Can Be as Effective as Traditional Learning for Medical Students in the Initial Assessment of Trauma Patients.

Distance learning is expanding and replacing the traditional academic medical settings. Managing trauma patients seems to be a prerequisite skill for medical students. This study has been done to evaluate the efficiency of distance learning on performing the initial assessment and management in trauma patients, compared with the traditional learning among senior medical students. One hundred and twenty senior medical students enrolled in this single-blind quasi-experimental study and were equally divided into the experimental (distance learning) and control group (traditional learning). All participants did a written MCQ before the study. The control group attended a workshop with a 50-minute lecture on initial management of trauma patients and a case simulation scenario followed by a hands-on session. On the other hand, the experimental group was given a DVD with a similar 50-minute lecture and a case simulation scenario, and they also attended a hands-on session to practice the skills. Both groups were evaluated by a trauma station in an objective structured clinical examination (OSCE) after a month. The performance in the experimental group was statistically better (P=0.001) in OSCE. Distance learning seems to be an appropriate adjunct to traditional learning.

Diagnostic accuracy of emergency-performed focused assessment with sonography for trauma (FAST) in blunt abdominal trauma.

INTRODUCTION: Intra-abdominal hemorrhage due to blunt abdominal trauma is a major cause of trauma-related mortality. Therefore, any action taken for facilitating the diagnosis of intra-abdominal hemorrhage could save the lives of patients more effectively. The aim of this study was to determine the accuracy of focused assessment with sonography for trauma (FAST) performed by emergency physicians. METHODS: In this cross-sectional study from February 2011 to January 2012 at 7th Tir Hospital in Tehran (Iran), 120 patients with abdominal blunt trauma were chosen and evaluated for abdominal fluid. FAST sonography was performed for all the subjects by emergency residents and radiologists while they were blind to the other tests. Abdominal CTs, which is the gold standard, were done for all of the cases. SPSS 20.0 was used to analyze the results. RESULTS: During the study, 120 patients with abdominal blunt trauma were evaluated; the mean age of the patients was 33.0 ± 16.6 and the gender ratio was 3/1 (M/F). The results of FAST sonography by emergency physicians showed free fluid in the abdomen or pelvic spaces in 33 patients (27.5%), but this was not observed by the results of CT scans of six patients; sensitivity and specificity were 93.1 and 93.4%, respectively. As for tests performed by radiology residents, sensitivity was a bit higher (96.5%) with lower specificity (92.3%). CONCLUSION: The results suggested that emergency physicians can use ultrasonography as a safe and reliable method in evaluating blunt abdominal trauma.

Contextualization and validation of the interprofessional collaborator assessment rubric (ICAR) through simulation: Pilot investigation.

BACKGROUND: Simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. The aim of this study was to contextualize and assess the validity and reliability of the Interprofessional Collaborative Assessment tool (ICAR) in an Iranian context using simulation. METHODS: In this descriptive study, contextualization of the ICAR was assessed through several steps. Firstly, validity assessment was approved through expert panels and Delphi rounds. Secondly, reliability assessment was done by arranging a simulation video and assessing reproducibility, test-retest (ICC), internal consistency (Cronbach's Alpha) and inter-rater reliability (Kappa).The participants included 26 experts, 27 students and 6 staff of the Standardized Simulation Office of Teheran University of Medical Sciences. RESULTS: Contextualization and validity of the ICAR were approved in an Iranian context. The reliability of the tool was computed to be 0.71 according to Cronbach´s Alpha. The test-retest was calculated to be 0.76. CONCLUSION: The Iranian ICAR can be a useful tool for evaluating interprofessional collaborative competencies. The development of the instrument through a simulation scenario has been a positive prospect for researchers.

Emergency medicine as a growing career in Iran: an Internet-based survey.

BACKGROUND: In Iran, few studies have evaluated emergency medicine as a career option. In the present study, we aimed to find out how Iranian emergency-medicine specialists view their specialty as a career. METHODS: Following a qualitative study, a Likert-scale questionnaire was developed. Iranian emergency physician specialists who had at least two years' job experience were contacted via email. A uniform link to a Web-based survey and a cover letter that explained the survey were sent to the recipients. We used the Kruskal-Wallis test and post hoc analysis to determine the differences between demographic subgroups. RESULTS: A total of 109 eligible responses were received, a response rate of 72.63%. Of the responders, 57.8% were 30-40 years of age, 86.2% were male, 86.2% were single, 84.4% were faculty members and 90.8% had fewer than 10 years' job experience. The main problems occurring during the career of Iranian emergency physicians were: insufficient income, inadequate recognition of the specialty by the community, inadequate union support, insecurity in the emergency wards, overcrowding, job stresses and night shifts. Despite insufficiency of income, Iranian emergency physicians (EPs) did not care about the financial benefits of patient care. Academic activity had positive effects on the perspectives of Iranian emergency physicians regarding their careers. CONCLUSION: Iranian emergency physicians and leaders in emergency medicine should struggle to improve the present situation, aiming at an ideal state.

The impact of using RUSH protocol for diagnosing the type of unknown shock in the emergency department.

Clinical assessment and classification of shock is extremely difficult to conduct on critically ill patients especially upon arrival at the emergency department. Resuscitative point-of-care ultrasound could be used for rapid initial diagnosis and better management. In this study, the results of using the RUSH (Rapid Ultrasound in Shock) exam to determine the type of shock in the emergency department are compared to the final diagnosis of patients. This was a single-center prospective study in which all patients with an unknown type of shock and no prior treatment were included. Parallel to the standard resuscitative management and diagnosis of the emergency team, the RUSH exam was performed blindly on the patient by an emergency medicine staff who was not part of the patient's caregiving team. The results of the RUSH exam were then compared to the final diagnosis of the patients and the 48-h outcome. Twenty-five patients were enrolled in this study. The overall kappa correlation of the RUSH exam compared with the final diagnosis was 0.84 which is an almost perfect agreement. The overall sensitivity of the RUSH exam was 88 % and the specificity was 96 %. Although the mortality rate was 64 %, there was not a significant relationship between mortality and the protocol used for diagnosis. The RUSH exam could be used in emergency wards to detect types of shock.
