Diagnostic tools in emergency medicine have been widely studied. As a non-invasive and quick tool, ultrasound plays a role in the field of emergency medicine. Thus, it is significant to understand the global scientific output of this topic. An analysis of publications on the use of ultrasound in emergency medicine over the past decade was performed and summarized to track the current hotspots and highlight future directions. Globally relevant publications on ultrasound in emergency medicine from 2009 to 2020 were extracted from the Web of Science collection database. VOSviewer software and CiteSpace were employed to visualize and predict the trends in the research on the topic. The overall volume of global publications is on the rise furthermore, the United States published the most publications in this field and had the most citations and H-index. in the United States has most publications in terms of institutions. published the most papers related to ultrasound in emergency medicine in terms of journals. Pulmonary embolism was once the main research direction, and importantly, "point-of-care ultrasound" was determined to be a new research hotspot. Altogether, the number of publications on ultrasound in emergency medicine will rise in the future. In addition, the findings reported here shed new light on the major progress on ultrasound in emergency medicine, which may be mutually cooperative in various fields. Moreover, this bibliometric study provides further indications for the topic of "point-of-care ultrasound".

Background: Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based practice that can identify adolescents who use alcohol and other drugs and support proper referral to treatment. Despite an American College of Surgeons mandate to deliver SBIRT in pediatric trauma care, trauma centers throughout the United States have faced numerous patient, provider, and organizational level barriers to SBIRT implementation. The Implementing Alcohol Misuse Screening, Brief Intervention, and Referral to Treatment Study (IAMSBIRT) aimed to implement SBIRT across 10 pediatric trauma centers using the Science-to-Service Laboratory (SSL), an empirically supported implementation strategy.

Background: Effective interventions to reduce drowning incidents require accurate and reliable data for scientific analysis. However, the lack of high-quality evidence and the variability in drowning terminology, definitions, and outcomes present significant challenges in assessing studies to inform drowning guidelines. Many drowning reports use inappropriate classifications for drowning incidents, which significantly contributes to the underreporting of drowning.

The coronavirus disease 2019 (COVID-19) interventions in interrupting transmission have paid heavy losses politically and economically. The Chinese government has replaced scaling up testing with monitoring focus groups and randomly supervising sampling, encouraging scientific research on the COVID-19 transmission curve to be confirmed by constructing epidemiological models, which include statistical models, computer simulations, mathematical illustrations of the pathogen and its effects, and several other methodologies. Although predicting and forecasting the propagation of COVID-19 are valuable, they nevertheless present an enormous challenge.
