The objective of this review is to document global clinical and nonclinical research priorities. The Emergency Medicine Education and Research by Global Experts network, consisting of 22 sites across six continents, conducted a mapping review of publications on emergency medicine research priorities (2000-2022) across seven databases. We included studies with replicable methodologies for determining research priorities, excluding those limited to individual diseases. Three reviewers independently screened, selected, and categorized results into clinical and nonclinical topics. Discrepancies were resolved by an independent investigator and consensus. Outcomes measures and analysis include descriptive analysis of research priorities grouped into clinical and nonclinical topics, characteristics of publications including countries represented in the author list, target audience (such as researchers or policy makers), participants (e.g. patients), and methods (e.g. Delphi) of priority setting. Among 968 screened papers, 57 publications from all WHO regions were included. Most (36, 63%) had authors from only a single country, primarily in North America and Europe. Patient representatives were included in only 10 (18%). Clinical research priorities clustered into resuscitation, cardiology, central nervous system, emergency medical services, infectious disease, mental health, respiratory disease, and trauma. Distribution was broad in North America and Europe but focused on infectious diseases and resuscitation in Africa and Asia. Eleven nonclinical topics included access to care, health policy, screening/triage, social determinants of health, staffing, technology/simulation, shared decision making, cross-sectoral collaboration, education, patient-centered care, and research networks. Nonclinical topics were broad in Europe and America, focused on access to care and health screening in Africa, and mostly absent in other WHO regions. Published research priorities in emergency medicine are heterogeneous and geographically limited, mostly containing groups of authors from the same country. The majority of publications in global research priority setting stem from Western countries, covering a broad spectrum of clinical and nonclinical topics. Research priorities from Africa and Asia tend to focus on specific issues more prevalent in those regions of the world.</p>","PeriodicalId":11893,"journal":{"name":"European Journal of Emergency Medicine","volume":" ","pages":"12-21"},"PeriodicalIF":3.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142282366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
