Medical student education simulation competitions.

BACKGROUND: Sim Wars is a simulation-based competition wherein teams of medical trainees are presented a clinical scenario and provide patient care in front of a live audience. This non-traditional educational offering is a form of serious games in medical education and allows for experiential learning via direct observation. Although a well-described educational modality within graduate medical education, there is a dearth of literature regarding Sim Wars as an educational tool within undergraduate medical education. In this paper, we aim to share student perspectives after participating in Sim Wars. APPROACH: The Sim Wars competition was designed as a double-elimination bracket tournament with arena-style direct observation to maximise student engagement. Teams were provided formative feedback in areas of medical knowledge, clinical management and communication skills. A total of 64 students participated in a regional Sim Wars tournament over the course of 2 years. EVALUATION: A total of 36 students completed Likert-based surveys immediately after the Sim Wars competition. Quantitative data and open-ended responses were analysed. Fourteen students participated in focus groups held a few months after Sim Wars regarding their experiences during the competition. Thematic analysis was systematically performed on the qualitative data. IMPLICATION: Participation in Sim Wars was viewed by students as a high-yield learning experience that increased competence on subsequent clinical rotations. We conclude that this form of serious game can be a highly beneficial educational format for medical students especially if they spend time preparing for the competition and receive structured feedback on their performance.

A Scoping Literature Review of Simulation Training Program Curriculum Standards.

SUMMARY STATEMENT: Simulation educator training is well supported in the literature and endorsed by the Society of Simulation in Healthcare as well as the International Nursing Association for Clinical Simulation and Learning. Despite growth of domestic and international training programs, there is a lack of consensus regarding curriculum standards. Our aim was to identify core curricular components of comprehensive simulation training programs. A scoping literature review of all relevant publications from 2000 to 2020 was conducted using a 6-step design. A team of 10 multidisciplinary, international simulation educators independently reviewed all citations with discrepancies resolved by third-person review. Of the initial 320 identified unique publications, a total of 15 articles were included, all published within the last 6 years. Four themes were identified: domains (n = 6), competencies (n = 3), objectives (n = 8), and other characteristics (n = 3). The findings support a greater understanding of the core curricular content across simulation training programs to support standardization.

Diagnostic and prognostic capabilities of a biomarker and EMR-based machine learning algorithm for sepsis.

Sepsis is a major cause of mortality among hospitalized patients worldwide. Shorter time to administration of broad-spectrum antibiotics is associated with improved outcomes, but early recognition of sepsis remains a major challenge. In a two-center cohort study with prospective sample collection from 1400 adult patients in emergency departments suspected of sepsis, we sought to determine the diagnostic and prognostic capabilities of a machine-learning algorithm based on clinical data and a set of uncommonly measured biomarkers. Specifically, we demonstrate that a machine-learning model developed using this dataset outputs a score with not only diagnostic capability but also prognostic power with respect to hospital length of stay (LOS), 30-day mortality, and 3-day inpatient re-admission both in our entire testing cohort and various subpopulations. The area under the receiver operating curve (AUROC) for diagnosis of sepsis was 0.83. Predicted risk scores for patients with septic shock were higher compared with patients with sepsis but without shock (p < 0.0001). Scores for patients with infection and organ dysfunction were higher compared with those without either condition (p < 0.0001). Stratification based on predicted scores of the patients into low, medium, and high-risk groups showed significant differences in LOS (p < 0.0001), 30-day mortality (p < 0.0001), and 30-day inpatient readmission (p < 0.0001). In conclusion, a machine-learning algorithm based on electronic medical record (EMR) data and three nonroutinely measured biomarkers demonstrated good diagnostic and prognostic capability at the time of initial blood culture.

Notes From the Field: Automatic Item Generation, Standard Setting, and Learner Performance in Mastery Multiple-Choice Tests.

Mastery learning assessments have been described in simulation-based educational interventions; however, studies applying mastery learning to multiple-choice tests (MCTs) are lacking. This study investigates an approach to item generation and standard setting for mastery learning MCTs and evaluates the consistency of learner performance across sequential tests. Item models, variables for question stems, and mastery standards were established using a consensus process. Two test forms were created using item models. Tests were administered at two training programs. The primary outcome, the test-retest consistency of pass-fail decisions across versions of the test, was 94% (κ = .54). Decision-consistency classification was .85. Item-level consistency was 90% (κ = .77, SE = .03). These findings support the use of automatic item generation to create mastery MCTs which produce consistent pass-fail decisions. This technique broadens the range of assessment methods available to educators that require serial MCT testing, including mastery learning curricula.

Severe Vitamin K-dependent Coagulopathy from Rodenticide-contaminated Synthetic Cannabinoids: Emergency Department Presentations.

INTRODUCTION: Synthetic cannabinoids are a rapidly expanding subset of designer drugs widely available in the United States since 2008. In Illinois during the spring of 2018, over 160 documented cases of bleeding and prolonged coagulopathy occurred secondary to contaminated synthetic cannabinoids. METHODS: We conducted a retrospective cohort study consisting of 38 patients to describe the initial emergency department (ED) presentation, diagnosis, and treatment. RESULTS: Through serum testing we found that three long-acting anticoagulant rodenticides (LAAR) were detected in patients who had inhaled these tainted products: brodifacoum, difenacoum, and bromodialone. DISCUSSION: This study encompasses the largest ED presentation of LAAR poisoning via the inhalational route known to date. CONCLUSION: The emergency physician should be aware of the potential for tainted coingestants as the cause of undifferentiated coagulopathy.

The Equivalence of Video Self-review Versus Debriefing After Simulation: Can Faculty Resources Be Reallocated?

INTRODUCTION: Traditional simulation debriefing is both time- and resource-intensive. Shifting the degree of primary learning responsibility from the faculty to the learner through self-guided learning has received greater attention as a means of reducing this resource intensity. The aim of the study was to determine if video-assisted self-debriefing, as a form of self-guided learning, would have equivalent learning outcomes compared to standard debriefing. METHODS: This randomized cohort study consisting of 49 PGY-1 to -3 emergency medicine residents compared performance after video self-assessment utilizing an observer checklist versus standard debriefing for simulated emergency department procedural sedation (EDPS). The primary outcome measure was performance on the second EDPS scenario. RESULTS: Independent-samples t-test found that both control (standard debrief) and intervention (video self-assessment) groups demonstrated significantly increased scores on Scenario 2 (standard-t(40) = 2.20, p < 0.05; video-t(45) = 3.88, p < 0.05). There was a large and significant positive correlation between faculty and resident self-evaluation (r = 0.70, p < 0.05). There was no significant difference between faculty and residents self-assessment mean scores (t(24) = 1.90, p = 0.07). CONCLUSIONS: Residents receiving feedback on their performance via video-assisted self-debriefing improved their performance in simulated EDPS to the same degree as with standard faculty debriefing. Video-assisted self-debriefing is a promising avenue for leveraging the benefits of simulation-based training with reduced resource requirements.

Case Report of Spontaneous Thyroid Hemorrhage Following LMA Insertion.

A case of thyroid hemorrhage following laryngeal mask airway (LMA) intubation is described. A 42-year-old female presented to the emergency department (ED) with left neck pain after same day surgery with LMA intubation and was found to have a thyroid hemorrhage on imaging. The patient was ultimately discharged in stable condition with no acute interventions performed in the ED or by otorhinolaryngology (ENT). Airway implications and possible interventions based on isolated case reports are reviewed and discussed. Topics: Thyroid hemorrhage, LMA complications.

Impact of an Electronic App on Resident Responses to Simulated In-Flight Medical Emergencies: Randomized Controlled Trial.

BACKGROUND: Health care providers are often called to respond to in-flight medical emergencies, but lack familiarity with expected supplies, interventions, and ground medical control support. OBJECTIVE: The objective of this study was to determine whether a mobile phone app (airRx) improves responses to simulated in-flight medical emergencies. METHODS: This was a randomized study of volunteer, nonemergency resident physician participants who managed simulated in-flight medical emergencies with or without the app. Simulations took place in a mock-up cabin in the simulation center. Standardized participants played the patient, family member, and flight attendant roles. Live, nonblinded rating was used with occasional video review for data clarification. Participants participated in two simulated in-flight medical emergencies (shortness of breath and syncope) and were evaluated with checklists and global rating scales (GRS). Checklist item success rates, key critical action times, GRS, and pre-post simulation confidence in managing in-flight medical emergencies were compared. RESULTS: There were 29 participants in each arm (app vs control; N=58) of the study. Mean percentages of completed checklist items for the app versus control groups were mean 56.1 (SD 10.3) versus mean 49.4 (SD 7.4) for shortness of breath (P=.001) and mean 58 (SD 8.1) versus mean 49.8 (SD 7.0) for syncope (P<.001). The GRS improved with the app for the syncope case (mean 3.14, SD 0.89 versus control mean 2.6, SD 0.97; P=.003), but not the shortness of breath case (mean 2.90, SD 0.97 versus control mean 2.81, SD 0.80; P=.43). For timed checklist items, the app group contacted ground support faster for both cases, but the control group was faster to complete vitals and basic exam. Both groups indicated higher confidence in their postsimulation surveys, but the app group demonstrated a greater increase in this measure. CONCLUSIONS: Use of the airRx app prompted some actions, but delayed others. Simulated performance and feedback suggest the app is a useful adjunct for managing in-flight medical emergencies.

Simulation-based Remediation in Emergency Medicine Residency Training: A Consensus Study.

INTRODUCTION: Resident remediation is a pressing topic in emergency medicine (EM) training programs. Simulation has become a prominent educational tool in EM training and been recommended for identification of learning gaps and resident remediation. Despite the ubiquitous need for formalized remediation, there is a dearth of literature regarding best practices for simulation-based remediation (SBR). METHODS: We conducted a literature search on SBR practices using the terms "simulation," "remediation," and "simulation based remediation." We identified relevant themes and used them to develop an open-ended questionnaire that was distributed to EM programs with experience in SBR. Thematic analysis was performed on all subsequent responses and used to develop survey instruments, which were then used in a modified two-round Delphi panel to derive a set of consensus statements on the use of SBR from an aggregate of 41 experts in simulation and remediation in EM. RESULTS: Faculty representing 30 programs across North America composed the consensus group with 66% of participants identifying themselves as simulation faculty, 32% as program directors, and 2% as core faculty. The results from our study highlight a strong agreement across many areas of SBR in EM training. SBR is appropriate for a range of deficits, including procedural, medical knowledge application, clinical reasoning/decision-making, communication, teamwork, and crisis resource management. Simulation can be used both diagnostically and therapeutically in remediation, although SBR should be part of a larger remediation plan constructed by the residency leadership team or a faculty expert in remediation, and not the only component. Although summative assessment can have a role in SBR, it needs to be very clearly delineated and transparent to everyone involved. CONCLUSION: Simulation may be used for remediation purposes for certain specific kinds of competencies as long as it is carried out in a transparent manner to all those involved.

Emergency department management of priapism [digest].

Priapism is a genitourinary emergency that demands a thorough, time-sensitive evaluation. There are 3 types of priapism: ischemic, nonischemic, and recurrent ischemic priapism; ischemic priapism accounts for 95% of cases. Ischemic priapism must be treated within 4 to 6 hours to minimize morbidity, including impotence. The diagnosis of ischemic priapism relies heavily on the history and physical examination and may be facilitated by penile blood gas analysis and penile ultrasound. This issue reviews current evidence regarding emergency department treatment of ischemic priapism using a stepwise approach that begins with aspiration of cavernosal blood, cold saline irrigation, and penile injection with sympathomimetic agents. Evidence-based management and appropriate urologic follow-up of nonischemic and recurrent ischemic priapism maximizes patient outcomes and resource utilization.
