Methods: Following PRISMA-ScR guidelines, we searched MEDLINE, PsycINFO, CINAHL Complete, and EMBASE from inception to May 2025 for empirical studies examining ED frequent attendance with alcohol involvement. Definitions had high heterogeneity; therefore, narrative synthesis was conducted. Results: A total of 73 studies were included, most retrospective (57.5%), encompassing sample sizes from 14 to over 4.1 million participants: 59 frequent attender (FA) studies with alcohol subgroup analyses and 14 pure ARFA studies. Research was concentrated in North America and Europe (56\/73, 76.7%), with limited Asia-Pacific representation (21.9%). Seven distinct definition threshold categories were identified (\u22652 to \u226520 visits annually); 31.5% utilised different definitions. Qualitative studies (n = 6) identified push factors (dependence, mental health crises, housing instability, fragmented services) and pull factors (24\/7 access, crisis care model, immediate service) driving frequent attendance. Eight studies evaluated interventions; all employed non-randomised designs examining case management, integrated pathways, and community-based treatments. Conclusions: Critical gaps include the absence of standardised definitions for comparison across studies, a concentration of research in Western settings limiting global applicability, and insufficient rigorous intervention evidence. Priorities include developing empirically validated definitions, expanding non-Western research, and conducting randomised controlled trials with adequate follow-up.<\/jats:p>","DOI":"10.3390\/jcm15134892","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T03:09:17Z","timestamp":1782270557000},"page":"4892","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Alcohol-Related Frequent Attenders to Emergency Departments: A Scoping Review with Implications for Singapore"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9401-4715","authenticated-orcid":false,"given":"Juntian","family":"Wu","sequence":"first","affiliation":[{"name":"Pre-Hospital and Emergency Research Centre (PERC), Duke-NUS Medical School, 8 College Road, Singapore 169857, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7874-7612","authenticated-orcid":false,"given":"Marcus Eng Hock","family":"Ong","sequence":"additional","affiliation":[{"name":"Emergency Department, Singapore General Hospital, Outram Road, Singapore 169608, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Desmond Renhao","family":"Mao","sequence":"additional","affiliation":[{"name":"Acute And Emergency Care, Khoo Teck Puat Hospital, 90 Yishun Central, Singapore 768828, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5726-9965","authenticated-orcid":false,"given":"Mikael","family":"Hartman","sequence":"additional","affiliation":[{"name":"Division of General Surgery (Breast Surgery), Department of Surgery, National University Hospital, 5 Lower Kent Ridge Road, Singapore 119074, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1233-7642","authenticated-orcid":false,"given":"Xueling","family":"Sim","sequence":"additional","affiliation":[{"name":"Saw Swee Hock School of Public Health, National University of Singapore, 21 Lower Kent Ridge Road, Singapore 119077, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1403-8993","authenticated-orcid":false,"given":"Benjamin Sieu-Hon","family":"Leong","sequence":"additional","affiliation":[{"name":"Emergency Medicine Department, National University Hospital, 5 Lower Kent Ridge Road, Singapore 119074, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3512-2950","authenticated-orcid":false,"given":"Rachel Siying","family":"Lee","sequence":"additional","affiliation":[{"name":"Saw Swee Hock School of Public Health, National University of Singapore, 21 Lower Kent Ridge Road, Singapore 119077, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9046-5105","authenticated-orcid":false,"given":"Fahad Javaid","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Pre-Hospital and Emergency Research Centre (PERC), Duke-NUS Medical School, 8 College Road, Singapore 169857, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1016\/j.annemergmed.2010.01.032","article-title":"Frequent users of emergency departments: The myths, the data, and the policy implications","volume":"56","author":"LaCalle","year":"2010","journal-title":"Ann.
