Does Inclusion of Emergency Medicine (EM) Residents in ECG Screening for STEMI Change the Time to Catheterization Lab Activation?

BACKGROUND: Emergency medicine physicians must rapidly obtain and interpret an electrocardiogram (ECG) to quickly identify life-threatening cardiac emergencies such as ST-elevation myocardial infarction (STEMI). Although ECG interpretation is a critical component of residency education, few high-powered studies exploring the accuracy of resident ECG interpretation exist. OBJECTIVES: This study aims to evaluate whether or not the inclusion of Third Year Emergency Medicine Resident ECG interpretations is noninferior to attending-only ECG interpretations in regard to time to STEMI activation. METHODS: This was a retrospective noninferiority study of STEMI activation times before and after the inclusion of Third Year Emergency Medicine Resident resident ECG interpretations into the workflow at an academic, urban tertiary care center between November 2020 and April 2022, excluding prehospital activations. The primary outcome was the proportion of successful STEMI activations initiated within 5 minutes of ECG completion. An absolute decrease of 10% between groups was chosen as the noninferiority margin. RESULTS: In the attending-only group, 26 (66.7%) cases resulted in successful STEMI activations compared to 31 cases (77.5%) in the combined group. The proportion of successful STEMI activations did not differ with resident screening, X 2 = 1.15, P = 0.28. The absolute difference between groups' successful activations was an increase of 11%, which lies within the noninferiority margin (+11%, 95% confidence interval, -8.68% to 30.7%). Average times to STEMI activation in the attending-only and combined groups were 7.59 minutes (Standard Deviation [SD], 10.19) and 5.13 minutes (SD, 6.95), respectively. Average door-to-balloon times for those undergoing Percutaneous Coronary Intervention were 72.74 minutes (SD, 20.76) in the attending-only group and 89.90 minutes (SD, 67.74) in the combination group. Two sample t-test showed no statistically significant difference between the 2 groups for average time to STEMI activation (difference = 2.46 minutes, 95% CI, -1.46 to 6.38) and average door-to-balloon time (difference = 17.16, 95% CI, -39.73 to 5.41). CONCLUSION: The inclusion of emergency medicine PGY-3 residents in the ECG screening workflow is noninferior to attending-only interpretation of ECGs with regard to STEMI activation time.

Does the Electrocardiogram Machine Interpretation Affect the Ability to Accurately Diagnose ST-Elevation Myocardial Infarction by Emergency Physicians?

INTRODUCTION: An ST-elevation myocardial infarction (STEMI) can portend significant morbidity and mortality to the patient and therefore must be rapidly diagnosed by an emergency medicine (EM) physician. The primary aim of this study is to determine whether EM physicians are more or less likely to accurately diagnose STEMI on an electrocardiogram (ECG) if they are blinded to the ECG machine interpretation as opposed to if they are provided the ECG machine interpretation. METHODS: We performed a retrospective chart review of adult patients over 18 years of age admitted to our large, urban tertiary care center with a diagnosis of STEMI from January 1, 2016, to December 31, 2017. From these patients' charts, we selected 31 ECGs to create a quiz that was presented twice to a group of emergency physicians. The first quiz contained the 31 ECGs without the computer interpretations revealed. The second quiz, presented to the same physicians 2 weeks later, contained the same set of ECGs with the computer interpretations revealed. Physicians were asked "Based on the ECG above, is there a blocked coronary artery present causing a STEMI?" RESULTS: Twenty-five EM physicians completed two 31-question ECG quizzes for a total of 1550 ECG interpretations. On the first quiz with computer interpretations blinded, the overall sensitivity in identifying a "true STEMI" was 67.2% with an overall accuracy of 65.6%. On the second quiz in which the ECG machine interpretation was revealed, the overall sensitivity was 66.4% with an accuracy of 65.8 % in correctly identifying a STEMI. The differences in sensitivity and accuracy were not statistically significant. CONCLUSION: This study demonstrated no significant difference in physicians blinded versus those unblinded to computer interpretations of possible STEMI.

Emergency department management of acute asthma exacerbations.

Asthma is a disease of the airways characterized by inflammation, hyperresponsiveness, and bronchoconstriction. The diagnosis is primarily a clinical one, based on a focused history and physical examination, to differentiate from other entities such as heart failure, pneumonia, and pulmonary embolism. Radiographs, laboratory studies, and blood gases are not routinely recommended, except in atypical or refractory cases, or if there is diagnostic uncertainty. The cornerstone of acute asthma treatment includes short-acting beta agonists, anticholinergics, and systemic corticosteroids. This issue reviews the latest evidence in diagnostic and treatment strategies, including other pharmacologic treatments and newer management strategies to avoid intubation.

A Case of a Missing Proximal Humerus.

CASE PRESENTATION: In this case, we demonstrate how a small radiolucency in the proximal humerus can progress to an even larger problem within a few months in a patient without follow-up. Our patient's ultimate diagnosis was renal cell carcinoma with metastasis to the right proximal humerus, completely obliterating the affected bone. DISCUSSION: In many underserved communities, patients have limited access to medical care, particularly specialty care. These patients often present to the emergency department and are unable to acquire appropriate follow-up. This situation illustrates the social issues that our patients face every day affecting their access to healthcare and ultimately necessary medical treatment.

Does the Removal of Textbook Reading from Emergency Medicine Resident Education Negatively Affect In-Service Scores?

INTRODUCTION: In-service exam scores are used by residency programs as a marker for progress and success on board exams. Conference curriculum helps residents prepare for these exams. At our institution, due to resident feedback a change in curriculum was initiated. Our objective was to determine whether assigned Evidence-Based Medicine (EBM) articles and Rosh Review questions were non-inferior to Tintinalli textbook readings. We further hypothesized that the non-textbook assigned curriculum would lead to higher resident satisfaction, greater utilization, and a preference over the old curriculum. METHODS: We collected scores from both the allopathic In-training Examination (ITE) and osteopathic Emergency Medicine Residency In-service Exam (RISE) scores taken by our program's residents from both the 2015-2016 and 2016-2017 residency years. We compared scores pre-curriculum change (pre-CC) to scores post-curriculum change (post-CC). A five-question survey was sent to the residents regarding their satisfaction, preference, and utilization of the two curricula. RESULTS: Resident scores post-CC were shown to be non-inferior to their scores pre-CC for both exams. There was also no significant difference when we compared scores from each class post-CC to their respective class year pre-CC for both exams. Our survey showed significantly more satisfaction, utilization, and preference for this new curriculum among residents. CONCLUSION: We found question-based learning and Evidence-Based Medicine articles non-inferior to textbook readings. This study provides evidence to support a move away from textbook readings without sacrificing scores on examinations.

Professionalism Milestones Assessments Used by Emergency Medicine Residency Programs: A Cross-sectional Survey.

INTRODUCTION: Professionalism is a vital component of quality patient care. While competency in professionalism is Accreditation Council for Graduate Medical Education (ACGME)-mandated, the methods used to evaluate professionalism are not standardized, calling into question the validity of reported measurements. We aimed to determine the type and frequency of methods used by United States (US) -based emergency medicine (EM) residencies to assess accountability (Acc) and professional values (PV), as well as how often graduating residents achieve competency in these areas. METHODS: We created a cross-sectional survey exploring assessment and perceived competency in Acc and PV, and then modified the survey for content and clarity through feedback from emergency physicians not involved in the study. The final survey was sent to the clinical competency committee (CCC) chair or program director (PD) of the 185 US-based ACGME-accredited EM residencies. We summarized results using descriptive statistics and Fisher's exact testing. RESULTS: A total of 121 programs (65.4%) completed the survey. The most frequently used methods of assessment were faculty shift evaluation (89.7%), CCC opinion (86.8%), and faculty summative evaluation (76.4%). Overall, 37% and 42% of residency programs stated that nearly all (greater than 95%) of their graduating residents achieve mastery of Acc and PV non-technical skills, respectively. Only 11.2% of respondents felt their programs were very effective at determining mastery of non-technical skills. CONCLUSION: EM residency programs relied heavily on faculty shift evaluations and summative opinions to determine resident competency in professionalism, with feedback from peers, administrators, and other staff less frequently incorporated. Few residency programs felt their current methods of evaluating professionalism were very effective.

Effectiveness of 2-hour Troponin in High-risk Patients With Suspected Acute Coronary Syndrome.

BACKGROUND: Research has shown the safety and effectiveness of drawing a standard troponin level at presentation and again at 2 hours in only low-risk patients. Because high-sensitivity troponins are not currently approved in the United States, we studied the utility of a standard troponin that is presently in use. Our goal was to determine if 2-hour standard troponin would be safe and effective in the evaluation of a high-risk cohort of patients never studied previously. METHODS: We conducted a single-center prospective observational study of adult patients presenting to the emergency department with signs and symptoms suggestive of acute coronary syndrome. Patients were defined as high risk if the attending physician planned to admit or transfer the patient to the observation unit. History, Electrocardiography, Age, Risk factors, Troponin scores were calculated on all patients to provide verification that the individuals were high risk. The primary outcome was a composite of 30-day myocardial infarction, death, cardiac arrest with return of spontaneous circulation, or dysrhythmia. The secondary outcome was 30-day revascularization. RESULTS: We included a total of 122 patients with an average follow-up of 112 days (minimum 30 days). A total of 86% of cases had History, Electrocardiography, Age, Risk factors, Troponin scores ≥4. The primary outcome was met in 22 (18%) patients, and the secondary outcome occurred in 7 (5.7%) patients. The negative predictive value of negative 2-hour troponins along with no significant delta troponin rise was 98.7%. CONCLUSIONS: Discharging patients thought to be high risk who have negative troponins at 0 and 2 hours and no delta troponin rise appears safe. No deaths occurred in follow-up. Larger studies are warranted.

Bifrontal brain abscesses secondary to orbital cellulitis and sinusitis extension.

BACKGROUND: Intracranial abscesses are rare and life-threatening conditions that typically originate from direct extension from nearby structures, hematogenous dissemination or following penetrating cerebral trauma or neurosurgery. FINDINGS: A 36-year-old male presented to our emergency department with complaints of left eye swelling, headache and drowsiness. On physical exam, the patient was febrile and his left upper eyelid was markedly swollen with fluctuance and drainage. Maxillofacial computed tomography was obtained to evaluate for orbital pathology but revealed bifrontal brain abscesses. CONCLUSIONS: Brain abscesses should be considered in the differential diagnosis for patients who present with the classic triad of headache, fever and neurological deficit.

News media coverage of medication research: reporting pharmaceutical company funding and use of generic medication names.

CONTEXT: The news media are an important source of information about medical research for patients and even some physicians. Little is known about how frequently news articles report when medication research has received funding from pharmaceutical companies or how frequently news articles use generic vs brand medication names. OBJECTIVES: To assess the reporting of pharmaceutical company funding and generic medication name use in news articles about medication studies and to determine the views of newspaper editors about these issues. DESIGN, SETTING, AND PARTICIPANTS: We reviewed US news articles from newspaper and online sources about all pharmaceutical company-funded medication studies published in the 5 most prominent general medical journals between April 1, 2004, and April 30, 2008. We also surveyed editors at the 100 most widely circulated newspapers in the United States. MAIN OUTCOME MEASURES: The percentage of news articles indicating when studies have been pharmaceutical company-funded and the percentage that refer to medications by their generic vs brand names. Also the percentage of newspaper editors who indicate that their articles report pharmaceutical company funding; the percentage of editors who indicate that their articles refer to medications by generic names; and the percentage of newspapers with policies about these issues. RESULTS: Of the 306 news articles about medication research identified,130 (42%; 95% confidence interval [CI], 37%-48%) did not report that the research had received company funding. Of the 277 of these articles reporting on medications with both generic and brand names, 186 (67%; 95% CI, 61%-73%) referred to the study medications by their brand names in at least half of the medication references. Eighty-two of the 93 (88%) newspaper editors who responded to our survey reported that articles from their publications always or often indicated when studies had received company funding (95% CI, 80%-94%), and 71 of 92 (77%) responding editors also reported that articles from their publications always or often referred to medications by the generic names (95% CI, 67%-85%). However, only 3 of 92 newspapers (3%) had written policies stating that company funding sources of medical studies be reported (95% CI 1%-9%), and 2 of 93 (2%) newspapers had written policies stating that medications should be referred to by their generic names (95% CI 1%-8%). CONCLUSION: News articles reporting on medication studies often fail to report pharmaceutical company funding and frequently refer to medications by their brand names despite newspaper editors' contention that this is not the case.
