Faculty Evaluations Correlate Poorly with Medical Student Examination Performance in a Fourth-Year Emergency Medicine Clerkship.

BACKGROUND: Clerkship directors routinely evaluate medical students using multiple modalities, including faculty assessment of clinical performance and written examinations. Both forms of evaluation often play a prominent role in final clerkship grade. The degree to which these modalities correlate in an emergency medicine (EM) clerkship is unclear. OBJECTIVE: We sought to correlate faculty clinical evaluations with medical student performance on a written, standardized EM examination of medical knowledge. METHODS: This is a retrospective study of fourth-year medical students in a 4-week EM elective at one academic medical center. EM faculty performed end of shift evaluations of students via a blinded online system using a 5-point Likert scale for 8 domains: data acquisition, data interpretation, medical knowledge base, professionalism, patient care and communication, initiative/reliability/dependability, procedural skills, and overall evaluation. All students completed the National EM M4 Examination in EM. Means, medians, and standard deviations for end of shift evaluation scores were calculated, and correlations with examination scores were assessed using a Spearman's rank correlation coefficient. RESULTS: Thirty-nine medical students with 224 discrete faculty evaluations were included. The median number of evaluations completed per student was 6. The mean score (±SD) on the examination was 78.6% ± 6.1%. The examination score correlated poorly with faculty evaluations across all 8 domains (ρ 0.074-0.316). CONCLUSION: Faculty evaluations of medical students across multiple domains of competency correlate poorly with written examination performance during an EM clerkship. Educators need to consider the limitations of examination score in assessing students' ability to provide quality patient clinical care.

Impact of an end-of-fourth-year emergency medicine bootcamp.

BACKGROUND: The final months of the fourth-year of medical school are variable in educational and clinical experience, and the effect on clinical knowledge and preparedness for residency is unclear. Specialty-specific "bootcamps" are a growing trend in medical education aimed at increasing clinical knowledge, procedural skills, and confidence prior to the start of residency. METHODS: We developed a 4-week Emergency Medicine (EM) bootcamp offered during the final month of medical school. At the conclusion of the course, participants evaluated its impact. EM residency-matched participants and non-participants were asked to self-evaluate their clinical knowledge, procedural skills and confidence 1 month into the start of residency. Program directors were surveyed to assess participants and non-participants across the same domains. A Fisher's exact test was performed to test whether responses between participants and non-participants were statistically different. RESULTS: From 2015 to 2018, 22 students participated in the bootcamp. The majority reported improved confidence, competence, and procedural skills upon completion of the course. Self-assessed confidence was significantly higher in EM-matched participants 1 month into residency compared to EM-matched non-participants (p = 0.009). Self-assessed clinical knowledge and procedural skill competency was higher in participants than non-participants but did not reach statistical significance. Program directors rated EM-matched participants higher in all domains but this difference was also not statistically significant. CONCLUSIONS: Participation in an EM bootcamp increases self-confidence at the start of residency among EM-matched residents. EM bootcamps and other specialty-specific courses at the end of medical school may ease the transition from student to clinician and may improve clinical knowledge and procedural skills.

A Simulation-Based Prospective Cohort Study on Teaching Best Practices in Firearms Safety.

BACKGROUND: Gun violence in the United States is a significant public health concern. The high rate of weapons carriage by Americans places medical providers at risk for exposure to firearms in the workplace and provides an opportunity for patient safety counseling. Few curricular interventions have been published on teaching firearms safety principles to medical providers. Given the risk of encountering firearms in the workplace and the opportunity to engage patients in firearms safety counseling, providers may benefit from dedicated training on safely handling firearms. METHODS: This was a prospective cohort pilot study of a simulation-based educational intervention for third- and fourth-year medical students enrolled in an emergency medicine subinternship and emergency medicine bootcamp elective. Before undergoing the educational intervention, students completed a preintervention simulation case during which they discovered a model firearm in the patient's belongings and were asked to remove it. Students then received the intervention that included a discussion and demonstration on how to safely remove a firearm in the clinical setting. Two weeks later, the students were presented with a model firearm in a different simulation case, which they needed to remove. During the preintervention and postintervention simulations, students were evaluated on their performance of the critical actions in firearm removal using an 8-item checklist. Students' scores on this checklist were compared. RESULTS: Fifty-three students participated in the study, 25 of whom completed the postintervention assessment. The median number of correctly performed critical actions preintervention was 5 (interquartile range = 4-6) and postintervention was 7 (interquartile range = 6-8, P < 0.001). Students showed particular improvement in 4 steps: holding the firearm by the grip only, pointing the firearm in a safe direction at all times, removing the firearm from the immediate patient care area and placing it in a safe area, and ensuring that the firearm is monitored and untouched until police or security personnel arrive to secure it. CONCLUSIONS: This educational intervention is the first to formally teach students about the safe handling of firearms found in the clinical care space. This low-cost pilot project is easily transferrable to other training centers for teaching principles of safe firearms handling.

Diagnostic error, quality assurance, and medical malpractice/risk management education in emergency medicine residency training programs.

Background Diagnostic errors in emergency medicine (EM) can lead to patient harm as well as potential malpractice claims and quality assurance (QA) reviews. It is therefore essential that these topics are part of the core education of trainees. The methods training programs use to educate residents on these topics are unknown. The goal of this study was to identify the current methods used to teach EM residents about diagnostic errors, QA, and malpractice/risk management and determine the amount of educational teaching time EM programs dedicate to these topics. Methods An 11-item questionnaire pertaining to resident education on diagnostic errors, QA, and malpractice was sent through the Council of Emergency Medicine Residency Directors (CORD) listserv. Differences in the proportions of responses by duration of training program were analyzed using chi-squared or Fisher's exact tests. Results Fifty-four percent (91/168) of the EM programs responded. There was no difference in prevalence of formal education on these topics among 3- and 4-year programs. The majority of programs (59.5%) offer fewer than 4 h per year of additional QA education beyond morbidity and mortality rounds; a minority of the programs (18.8%) offer more than 4 h per year of medical malpractice/risk management education. Conclusions This needs assessment demonstrated that there is a lack of dedicated educational time devoted to these topics. A more formalized and standard curricular approach with increased time allotment may enhance EM resident education about diagnostic errors, QA, and malpractice/risk management.

A Multimodal Curriculum With Patient Feedback to Improve Medical Student Communication: Pilot Study.

INTRODUCTION: Despite the extraordinary amount of time physicians spend communicating with patients, dedicated education strategies on this topic are lacking. The objective of this study was to develop a multimodal curriculum including direct patient feedback and assess whether it improves communication skills as measured by the Communication Assessment Tool (CAT) in fourth-year medical students during an emergency medicine (EM) clerkship. METHODS: This was a prospective, randomized trial of fourth-year students in an EM clerkship at an academic medical center from 2016-2017. We developed a multimodal curriculum to teach communication skills consisting of 1) an asynchronous video on communication skills, and 2) direct patient feedback from the CAT, a 15-question tool with validity evidence in the emergency department setting. The intervention group received the curriculum at the clerkship midpoint. The control group received the curriculum at the clerkship's end. We calculated proportions and odds ratios (OR) of students achieving maximum CAT score in the first and second half of the clerkship. RESULTS: A total of 64 students were enrolled: 37 in the control group and 27 in the intervention group. The percentage of students achieving the maximum CAT score was similar between groups during the first half (OR 0.70, p = 0.15). Following the intervention, students in the intervention group achieved a maximum score more often than the control group (OR 1.65, p = 0.008). CONCLUSION: Students exposed to the curriculum early had higher patient ratings on communication compared to the control group. A multimodal curriculum involving direct patient feedback may be an effective means of teaching communication skills.

Fourth-year medical students do not perform a focused physical examination during a case-based simulation scenario.

BACKGROUND: The art of physical examination is one of the most valuable diagnostic tools bestowed upon new generations of medical students. Despite traditional educational techniques and significant attention on a national level, both trainees and educators have noticed a decrease in physical examination proficiency. Simulation has been identified as a potential way to improve physical examination techniques within undergraduate medical education. We sought to determine the utility of a cardiac case-based simulation scenario to assess physical examination performance of fourth-year medical students during an emergency medicine (EM) clerkship. MATERIALS AND METHODS: Fourth-year medical students enrolled in a 4-week EM clerkship were prospectively evaluated during a case-based scenario using a simulation mannequin (Laerdal SimMan®). The case involved a patient presenting with chest pain that evolved into cardiac arrest. All simulations were video recorded and two emergency physicians reviewed each video. The reviewers recorded whether or not each student completed the essential components of a focused physical examination. RESULTS: Twenty-seven students participated in the simulation. The percentage of students completing each of the four components of the physical examination was as follows: cardiac auscultation 33.3% (95% CI 18.5-52.3), lung auscultation 29.6% (95% CI 15.7-48.7), pulse and extremity examination 55.6% (95% CI 37.3-72.4), and abdominal examination 3.70% (95% CI 0-19.8). None of the students completed all four of these components. CONCLUSION: Our study showed that fourth-year medical students did not uniformly perform components of a focused physical examination during a high-acuity chest pain simulation scenario. Although our study showed limited physical examination performance, simulation allows evaluators to observe and provide constructive feedback and may lead to an improvement in these skills. These findings call for improved technology to increase authenticity of simulators and continued faculty development for more creative, meaningful integration of physical examination skills into high-acuity simulation cases.

Physician Variability in Management of Emergency Department Patients with Chest Pain.

INTRODUCTION: Chest pain is a common emergency department (ED) presentation accounting for 8-10 million visits per year in the United States. Physician-level factors such as risk tolerance are predictive of admission rates. The recent advent of accelerated diagnostic pathways and ED observation units may have an impact in reducing variation in admission rates on the individual physician level. METHODS: We conducted a single-institution retrospective observational study of ED patients with a diagnosis of chest pain as determined by diagnostic code from our hospital administrative database. We included ED visits from 2012 and 2013. Patients with an elevated troponin or an electrocardiogram (ECG) demonstrating an ST elevation myocardial infarction were excluded. Patients were divided into two groups: "admission" (this included observation and inpatients) and "discharged." We stratified physicians by age, gender, residency location, and years since medical school. We controlled for patient- and hospital-related factors including age, gender, race, insurance status, daily ED volume, and lab values. RESULTS: Of 4,577 patients with documented dispositions, 3,252 (70.9%) were either admitted to the hospital or into observation (in an ED observation unit or in the hospital), while 1,333 (29.1%) were discharged. Median number of patients per physician was 132 (interquartile range 89-172). Average admission rate was 73.7±9.5% ranging from 54% to 96%. Of the 3,252 admissions, 2,638 (81.1%) were to observation. There was significant variation in the admission rate at the individual physician level with adjusted odds ratio ranging from 0.42 to 5.8 as compared to the average admission. Among physicians' characteristics, years elapsed since finishing medical school demonstrated a trend towards association with a higher admission probability. CONCLUSION: There is substantial variation among physicians in the management of patients presenting with chest pain, with physician experience playing a role.

Pulmonary trauma emergency department evaluation and management.

Pulmonary trauma is a significant cause of morbidity and mortality in the United States. It is imperative for the emergency physician to identify promptly patients who require immediate therapy. In patients who have limited injuries, literature shows that often conservative management provides improved outcome. As the exposure to automobiles and firearms continues to increase in the setting of improved prehospital management, the emergency physician will encounter an increasing amount of pulmonary trauma. This rise in respiratory injuries will require a more aggressive approach of patients with minimal morbidity and mortality. A systematic approach to respiratory injuries is crucial to improving patient outcomes.

Myocarditis: emergency department recognition and management.

Myocarditis is an acute inflammatory syndrome involving the heart and related structures. In many instances, the presentation is obvious, and appropriate treatment and disposition follow accordingly. In other situations, patients present with viral illness of the respiratory or gastrointestinal tracts (or both) or nonspecific symptoms such as fatigue and weakness,leading the clinician astray. Management is largely supportive, including aggressive cardiorespiratory support.

Acute complications associated with shoulder dislocation at an academic Emergency Department.

Shoulder dislocation is the most frequent dislocation treated in the Emergency Department (ED). Orthopedic literature cites up to a 55% incidence of fracture, vascular or neurologic injury associated with this injury, but these studies suffer from referral bias. No large ED series has been reported. This retrospective chart review was conducted in an academic ED for patients with shoulder dislocation presenting July 1, 1995-June 30, 2000. There were 263 charts identified; 73 were miscoded and 5 were lost, leaving 190 for analysis. Mean age was 34.3 years. Fifty-five patients had at least one fracture (29%), 48 of which (76%) were of the Hill-Sachs type. Despite presence of a fracture, all shoulders underwent successful ED reduction. Sensory nerve deficits were found in 24 (12.6%), which persisted after reduction in 25% of these patients. No vascular injuries were identified. The finding of fracture in 33% of patients with shoulder dislocation is in the range of rates reported in the orthopedic literature (15-55%). The finding that, despite the presence of a fracture, all underwent successful closed reduction is important, as one-third of these patients will have this condition. Neurologic deficits in 12% is significantly lower than the 21-65% reported in the orthopedic literature. Although complications associated with shoulder dislocation were relatively common, they did not significantly affect ED management.

Lack of early defibrillation capability and automated external defibrillators in nursing homes.

OBJECTIVE: To determine the availability of early defibrillation and automated external defibrillators in nursing homes in selected cities. DESIGN: A standardized telephone survey was conducted of all skilled nursing facilities to characterize early defibrillation capabilities. SETTING: The study involved nursing homes in Philadelphia, Omaha, Seattle, and Boston. PARTICIPANTS: All skilled nursing facilities not physically attached to hospitals in the selected cities based on listings from the Centers for Medicare and Medicaid Services as of January 2004. MEASUREMENTS: Each site was queried as to whether or not they had an automated external defibrillator (AED), if they were physically freestanding facilities, if a manual defibrillator was present, and if staff were present 24 hours a day to use the defibrillator. Early defibrillation was defined as the presence of either a manual defibrillator or AED in addition to 24-hour trained staff availability. RESULTS: There were 126 nursing homes identified from the Medicare listing and 81% (102) responded to our phone survey. After exclusion of non-freestanding facilities, 90 nursing homes (71.4%) were available for analysis. Overall, 16.7% (95% CI 8.8-24.5) of nursing homes reported early defibrillation capabilities via manual defibrillator or AEDs; 6.7% (95% CI 1.4-11.9) of nursing homes reported AEDs; 10.0% (95% CI 3.7-16.3) of nursing homes reported manual defibrillators. Nursing homes in Seattle had a higher rate of early defibrillation capability than the other 3 cities. CONCLUSION: Despite the fact that nursing homes have been identified as locations with multiple cardiac arrests, the early defibrillation capabilities and prevalence of AEDs in this setting remains low. AEDs may play a role in improving survival from cardiac arrest in nursing homes. The placement of AEDs in nursing homes needs further consideration and study.

Electrocardiographic ST segment elevation: a comparison of AMI and non-AMI ECG syndromes.

Chest pain (CP) patients presenting to the ED may manifest electrocardiographic ST segment elevation (STE). AMI (acute myocardial infarction) is a less frequent cause of such abnormality and one of many patterns responsible for ST segment elevation in ED CP patients. We performed a retrospective comparative review of the electrocardiographic features of various STE syndromes, focusing on differences between AMI and non-AMI syndromes. The electrocardiograms (ECGs) of consecutive ED adult CP patients (with 3 serial troponin I determinations) were interpreted by 3 attending emergency physicians. These ECGs with STE represented the study population used for analysis. Various electrocardiographic features such as STE, ST segment depression (STD), STE morphology, anatomic distribution of STE, and the number of leads with STE were recorded; derived values such as total STE, total ST segment deviation, and average STE per lead were calculated. Interobserver reliability concerning STE morphology was determined. AMI was diagnosed by abnormal serum troponin I values (>0.1 mg/dL) followed by a rise and fall of the serum marker; STE diagnoses of non-AMI causes were determined by medical record review. Five hundred ninety-nine CP patients were entered in the study with 212 (35%) individuals showing STE, 55 (26%) with electrocardiographic AMI and 157 (74%) with non-AMI electrocardiographic syndromes. Anatomic location within the AMI group included 32 inferior and inferior variants, 18 anterior and anterior variants, and 5 lateral; non-AMI anatomic locations included 56 inferior and inferior variants, 98 anterior and anterior variants, and 3 lateral; anterior STE occurred significantly more often in non-AMI syndromes. Total STE was 15.3 mm in AMI patients and 7.4 mm in non-AMI patients (P =.0004). The number of leads with STE was not significantly different between the two groups, 3.4 mm in AMI and 4.1 in non-AMI syndromes. ST segment elevation per lead was not significantly different in the 2 groups, 4.4 mm in AMI versus 1.8 mm in non-AMI syndromes. Total ST segment deviation (sum of STE and STD) was significantly greater in AMI syndromes, 17.8 mm in AMI compared with 10.5 mm in non-AMI syndromes (P =.00009). The presence of STD occurred at statistically similar rates in both groups. The morphology of the STE occurred in significantly different rates between AMI and non-AMI patterns, concave more often in non-AMI patterns (P <.00001) and nonconcave more often in AMI (P <.00001). Non-AMI causes of STE account for the majority of electrocardiographic syndromes encountered in ED chest pain patients. These findings alone are not adequate to determine the electrocardiographic cause of the ST segment elevation in chest pain patients. When determining AMI versus non-AMI with the ECG, these various findings should be used in the consideration of the overall clinical picture (history, examination, and electrocardiogram) in chest pain patients with ST segment elevation.

Reciprocal ST segment depression: impact on the electrocardiographic diagnosis of ST segment elevation acute myocardial infarction.

Acute myocardial infarction (AMI) is one of many causes of electrocardiographic ST segment elevation (STE) in ED chest pain (CP) patients; at times, the electrocardiographic diagnosis may be difficult. Coexistent ST segment depression has been reported to assist in the differentiation of non-infarction causes of STE from AMI-related ST segment elevation. The objective was to determine the effect of AMI diagnosis on the presence of STD among ED CP patients with electrocardiographic STE. Adult CP patients with electrocardiographic STE in at least 2 anatomically distributed leads were reviewed for the presence or absence of ST segment depression in at least 1 lead and separated into 2 groups, both with and without ST segment depression. A comparison of the 2 groups was performed in 2 approaches: all STE patients and then only with STE patients who lacked confounding electrocardiographic pattern (bundle branch block [BBB], left ventricular hypertrophy [LVH], or right ventricular paced rhythm [VPR]). All patients in the study underwent prolonged observation in the ED (at least 8 hours) with 3 serial troponin T determinations and 3 electrocardiograms (ECG). AMI was diagnosed by abnormal serum troponin T values (>0.1 mg/dL); electrocardiographic STE diagnoses of non-AMI causes were determined by medical record review. There were 171 CP patients with STE were entered in the study with 112 (65.5%) individuals show ST segment depression. When considering all study patients, ST segment depression was present at statistically equal rates in AMI and non-AMI situations (P = NS). The sensitivity, specificity, positive predictive value, and negative predictive value for the electrocardiographic diagnosis of AMI were 63%, 34%, 30%, and 67%, respectively. Patients with confounding patterns (LVH 46, BBB 19, and VPR 6) were removed from the analysis group, leaving 100 patients for analysis; 38 of these patients had ST segment depression. When considering this group of study patients, ST segment depression was present significantly more often in AMI patients (P <.0001). The sensitivity, specificity, positive predictive value, and negative predictive value for the electrocardiographic diagnosis of AMI were 69%, 93%, 93%, and 71%, respectively. Clinical diagnoses were as follows: 56 AMI, 50 USAP, and 65 noncoronary syndrome. When all CP patients with electrocardiographic STE are considered, the presence of ST segment depression is not helpful in distinguishing AMI from non-AMI. If one considers only patterns which lack electrocardiographic ST segment depression caused by altered intraventricular conduction, the presence of ST segment depression strongly suggests the diagnosis of AMI. In these cases, reciprocal ST segment depression is of considerable value in establishing the electrocardiographic diagnosis of STE AMI.
