ObjectiveThe objective was to identify the most important and impactful peer-reviewed global emergency medicine (GEM) articles published in 2021. The top articles are summarized in brief narratives and accompanied by a comprehensive list of all identified articles that address the topic during the year to serve as a reference for clinicians, researchers, and policy makers.MethodsA systematic PubMed search was carried out to identify all GEM articles published in 2021. Title and abstract screening was performed by trained reviewers and editors to identify articles in one of three categories based on predefined criteria: disaster and humanitarian response (DHR), emergency care in resource-limited settings (ECRLS), and emergency medicine development (EMD). Included articles were each scored by two reviewers using established rubrics for original (OR) and review (RE) articles. The top 5% of articles overall and the top 5% of articles from each category (DHR, ECRLS, EMD, OR, and RE) were included for narrative summary.ResultsThe 2021 search identified 44,839 articles, of which 444 articles screened in for scoring, 25% and 22% increases from 2020, respectively. After removal of duplicates, 23 articles were included for narrative summary. ECRLS constituted the largest category (n = 16, 70%), followed by EMD (n = 4, 17%) and DHR (n = 3, 13%). The majority of top articles were OR (n = 14, 61%) compared to RE (n = 9, 39%).ConclusionsThe GEM peer-reviewed literature continued to grow at a fast rate in 2021, reflecting the continued expansion and maturation of this subspecialty of emergency medicine. Few high-quality articles focused on DHR and EMD, suggesting a need for further efforts in those fields. Future efforts should focus on improving the diversity of GEM research and equitable representation.© 2022 Society for Academic Emergency Medicine.
