Background The Emergency Department (ED) plays a key role in the identification and care of acute medical conditions, including cancer. In this scoping review, we aimed to determine the role of the ED in the acute diagnosis of cancer. Methods We conducted a scoping review of articles according to Preferred Reporting Items for Systematic Review and Meta‐Analyses (PRISMA) using PubMed and Google Scholar. We screened studies of adults with a new diagnosis of cancer in the ED. We included randomized control trials, prospective, retrospective, and cross‐sectional observational studies, and case reports published in English since 2000. We grouped the articles into categories based on their objectives and findings. Results Of the 4459 articles, we included 47 in the review. The identified studies fell into three major categories: (1) studies describing the incidental diagnosis of cancer in the ED (n = 11, 23%), (2) studies characterizing the acute initial presentation of cancer in the ED (n = 19, 41%), and (3) studies describing the ED as a pathway to cancer diagnosis in the healthcare system (n = 17, 36%). Across the studies, cancer diagnoses in the ED were more likely in patients with higher comorbidities, occurred at later stages, and resulted in worse survival rates. Conclusions The ED plays a prominent role in the initial diagnosis of cancer. Efforts must be made to integrate the ED within the cancer care continuum.

Introduction: In-flight medical emergencies occur in an estimated one out of 604 flights. Responding in this environment poses a unique set of challenges unfamiliar to most emergency medicine (EM) providers, including physical space and resource limitations. We developed a novel high-fidelity in-situ training curriculum focused on frequent or high-risk in-flight medical scenarios while replicating this austere environment.Methods: Our residency program coordinated with our local airport's chief of security and an airline-specific station manager to arrange the use of a grounded Boeing 737 commercial airliner during late evening/early morning hours. Eight stations reviewing in-flight medical emergency topics were reviewed, five of which were simulation scenarios. We created medical and first-aid kits that reflect equipment used by commercial airlines. Residents' self-assessed competency and medical knowledge were assessed both initially and postcurriculum using a standardized questionnaire.Results: Forty residents attended the educational event as learners. Self-assessed competency and medical knowledge increased after curriculum participation. All tested aspects of self-assessed competency had a statistically significant increase from a mean of 15.04 to 29.20 out of a maximum score of forty. The mean medical knowledge score increased from 4.65 to 6.93 out of 10 maximum points. Conclusion:A five-hour in-situ curriculum for reviewing in-flight medical emergencies increased selfassessed competency and medical knowledge for EM and EM-internal medicine residents. The curriculum was overwhelmingly well-received by learners.
