The most common precipitants are infections (viral or bacterial), rib infarction, and fat emboli.1,2,4 Patients commonly present with fever, dyspnea, cough, chills, chest pain, or hemoptysis.

In one study, 33% of abused children had a previous visit with a medical provider in which the abuse was found to have been missed.2 Many voices in the healthcare community have advocated for the implementation of routine screening, and studies have demonstrated the implementation of such screening in the emergency department (ED) increases the detection of child maltreatment.3-7 Child maltreatment screening tools are increasingly utilized in primary care and ED settings, but one has yet to be adapted or designed for universal use by emergency medical services (EMS) professionals in the prehospital care context. Because EMS providers are uniquely positioned to assess for maltreatment, they have traditionally been the only provider to interact with families in the home environment. Unfortunately, EMS rates of documentation of maltreatment is quite low. A recent study using the National Emergency Medical Services Information System database to evaluate EMS documentation of child maltreatment in patients ≤3 years of age compared to the national incidence of known maltreatment found an almost 15-fold discrepancy.8 There have been several attempts to elucidate the difficulties of and barriers to reporting by EMS providers. Markenson et al and Tiyyagura et al outlined several areas that potentially contribute to a lack of reporting: minimal continuing medical education (CME) on child maltreatment, knowledge of physical and historical details suspicious for abuse, knowledge of child development, limited clinical evaluation time in a fast-paced work environment, understanding of how to appropriately interact with families, and fear of being wrong.9,10 This class/escape room activity was developed to directly address several of these areas. Emergency medical service providers participate in traditional didactics (in the form of a short lecture), followed by an escape room activity in which they further explore and reinforce learning in a fun and memorable environment.

The traditional approach to ECG interpretation in medical school is primarily didactic, teaching: \"rate, rhythm, axis,\" etc. Throughout residency, EM residents continue to receive lectures and practical ECG teaching to independently interpret ECGs with accuracy and efficiency. In addition to basic rhythm interpretation, physicians must be able to identify cardiac ischemia, abnormal rhythms, and subtle ECG findings that could herald sudden death.1 Life-threatening diagnoses such as digitalis toxicity or hyperkalemia can be made promptly through ECG evaluation and catastrophic if missed. If correctly diagnosed through ECG, many channelopathies can be treated and cardiac events can be prevented.2,3 Lecture-based learning is a necessary part of medical education, but there is a need to supplement the traditional teaching approach with online learning modules. Online learning modules provide learners with an accessible and efficient tool that allows them to improve their ECG skills on their own time.</p><p><strong>Educational objectives: </strong>After completion of the module learners should be able to: 1) correctly recognize and identify ECG abnormalities including but not limited to abnormal or absent P waves, widened QRS intervals, ST elevations, abnormal QT intervals, and dysrhythmias that can lead to sudden cardiac death; and 2) synthesize findings into a succinct but accurate interpretation of the ECG findings.</p><p><strong>Educational methods: </strong>An online module was developed using Articulate 360 and was implemented with EM residents. The module covers common ECG findings seen in the emergency department including ischemia, atrioventricular blocks, and bundle branch blocks. The module uniquely emphasizes ECG findings of arrythmias that could lead to sudden cardiac death and highlights that diagnosing sudden cardiac death syndromes relies on both clinical presentation and specific ECG findings. Online modules have proven to be as effective as lecture-based learning at improving ECG interpretation among healthcare professionals and are convenient and easily accessible to the busy EM resident.4,5 Additionally, the module is self-paced, can be completed at any time, and includes elements of active learning by incorporating knowledge checks throughout. This allows learners in real time to see where individualized improvement is needed. The ease of embedment of self-paced questions into the module is one of the salient reasons why module-based learning can be superior to lecture-based learning. This allows for real time retrieval practice, feedback, and repetition, all of which can be powerful and effective tools for learning.6.</p><p><strong>Research methods: </strong>This module was offered at a ","PeriodicalId":73721,"journal":{"name":"Journal of education & teaching in emergency medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10332672/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9827263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction Ophthalmology is characteristically a weak area in both medical school and resident education. Medical students are rarely given formal didactic education on the use of the slit lamp or a systematic approach to examining the eye. For EM residents, this leads to inefficient and uncomfortable encounters with patients with eye complaints. We sought to develop a comprehensive emergency ophthalmology tutorial utilizing asynchronous learning followed by a hands-on skill session that would address this need. Educational Objectives By the end of this small group didactic, learners will be able to: 1) demonstrate ability to focus on the various components of the slit lamp exam 2) demonstrate understanding of a systematic approach to the eye exam 3) demonstrate appropriate use of the Diaton, iCare, and Tonopen tonometers. Educational Methods This two-hour small group didactic combines hands-on learning sessions to learn the slit lamp exam and tonometry measurement, with a systematic review of the eye exam to help learners better organize their exams and understand the use of necessary tools. Research Methods The emergency ophthalmology tutorial was initially designed as an education project in which we collected pre- and post-participation surveys regarding resident comfort with various components of the emergency eye exam. After the course residents received a post-course survey to complete. Given the positive feedback we received from our residents regarding the tutorial, we applied for Institutional Review Board (IRB) approval to publish our retrospective survey data. Our IRB waived the need for participant consent. Results Twelve emergency medicine residents including 11 interns and one post-graduate year (PGY) 2 resident participated in the emergency ophthalmology tutorial as part of our intern boot camp in July of 2021. Twelve PGY-1 residents initially signed up for the course and filled out the pre-participation survey but one of them was not able to attend their scheduled class, so a PGY-2 resident requested to attend. Prior to the course, we used a Likert scale from 1–7, finding that 61.5% (8/13) of participants felt very uncomfortable with performing slit lamp exams, 84.6% (11/13) felt very uncomfortable with using the Diaton tonometer, 76.9% (10/13) felt very uncomfortable with using the iCare tonometer, and 69.3% (9/13) felt uncomfortable or very uncomfortable with using a systematic approach to examining the eye.
